I was inspired to write this after talking with @preggome93 about his mom's pregnancies, and used some of his descriptions. This is obviously an incest story. I hope you all enjoy it!
Nobody was surprised that Mom was pregnant again. Even though most people would think she was too old to have any more kids. Her last baby, my little brother, was born three years ago when she was 41, and she swore that was her last one even though she loved being pregnant. I'm the oldest of seven, soon to be eight. My mom doesn't believe in birth control and was with child pretty much my whole life. I don't know if that's why I have a fetish for pregnant women but I always liked looking at Mom while her belly swelled up. Eight pregnancies have taken their toll on her body. I've seen pictures of her before she had kids and she looked almost skinny, but with each baby she got bigger and rounder and never dropped much of the weight after. You could probably describe her as an SSBBW. I already thought she was hot with her big sagging tits, huge ass, and thick thighs, but seeing her pregnant was something else. I have many great memories of cuddling up with her on the couch, feeling my next little sibling squirming around in her massive belly, and as I got older I realized I was sexually interested in both pregnant women and my mother.
This was at best an open secret between me and my mom. I had never said anything about it to her but she knew how obsessed I got with her boobs and belly whenever she had a bun in her oven, and she had once seen my internet history full of searches for pregnant porn. She's not a shy woman. She let me cuddle her, rub her bare belly and kiss it, lay with my head on her chest. I got to see her naked in her third trimester because she was so big she couldn't cover herself with a towel after a shower. She saw the way I looked at her and made no effort to cover up. When she sat on the sofa with her top open on her belly feeling my sibling move I got so horny a few times that I left the room and even went into the bathroom to have a wank to it. I wonder if she knew what was happening. There were a lot of us in a small space and privacy wasn't always possible.
So her previous pregnancies were already exciting to me, but this one is different. Not just because Mom is well into middle age, with her hair going gray and wrinkles forming around her mouth and forehead. Not just because she's bigger than ever, having put on maybe fifty pounds in the last nine months. The thing is, the baby girl in Mom's womb wasn't put there by my dad. I'm her father.
Being the oldest of so many kids, I got used to helping my mom around the house, especially when Dad wasn't there. Even as a little kid I liked taking this role as the "man of the house." Last year I was tasked with helping Mom plan my youngest brother's birthday party while my dad was away on business. I think I did a great job, and everyone had fun, especially all the kids' parents with the booze I provided. Mom was able to relax while I took care of everything, and she ended up getting quite drunk. I was tipsy too, and once the guests were gone and my siblings were in bed Mom hugged me and praised me and kissed me right on the lips. We'd always been very affectionate with one another, and not shy about our bodies, so that wasn't the biggest surprise, nor was the way she stripped in front of me while preparing for bed. But when I got in bed beside her, just as naked, things changed. She teased me at first, making fun of my hard-on, asking why I was hot for my fat old mom. I just kept telling her she was beautiful and reaching out to touch her and before we could think better of it I was on top of her, sinking into all that soft lovely flesh. I wish my memory of that night was clearer, given how important it became. I remember Mom's big fat titties in my face, bouncing under me as I thrusted. I remember her groaning like a stuck pig and me having to cover her mouth because I was worried my brothers and sisters would hear her. I remember how hot and wet her pussy was, even if it wasn't very tight, and the excitement of finally getting inside her after years of lusting after her making it so I didn't last long. I remember how amazing it felt to cum in my mother, and how immediately I wanted to do it again.
I tried to talk to her about it the day after and she pretended like it didn't happen. I was devastated that I'd achieved my dream but would never get to do it again. My dad came home from business, my mom told him about the great party I'd thrown, and not long after I heard them fucking upstairs. I burned with jealousy.
Mom has been pregnant so many times we all know the telltale signs. She doesn't get morning sickness. Maybe she did with the first one or two babies, but her body is so used to pregnancy it doesn't seem to have that effect on her. What happens first is she gets really tired for a few weeks. She's a busy woman, with so many kids and a husband to take care of, but she doesn't fall asleep snoring on the couch watching TV unless she's knocked up, or take naps during the day. So when she started dozing off a lot late last year I got suspicious. My siblings would make jokes about it; even they were old enough to know what it meant. I was shocked. I assumed Mom was far too old to have another baby, and hadn't even considered that possibility after we'd fucked. But the next sign came when she got her energy back and started eating everything in the house. The craving stage would start at the end of her first trimester and not really let up until the very end. By New Year's Mom's belly was noticeably swollen, earlier than in any of her other pregnancies, I later found out. We just had to wait for the announcement.
Nobody was surprised when Mom and Dad sat us all down and explained that we would have a new baby brother or sister by the summer. My brothers and sisters congratulated her and swarmed her and rubbed her already quite sizable tummy, and Mom seemed happy enough even if she looked far too old to be having a baby. The surprise came when, later that night, Mom knocked on my door and sat on my bed, giving me a little talk in private.
"The baby's yours," she whispered, the first time she acknowledged that we'd had sex all those months ago. "We weren't careful." She didn't seem happy about it now.
I had been wondering if this was the case but it still shocked me to hear her say it. A pit opened in my stomach. I couldn't believe I'd knocked up my own mother. I felt ill but also excited. I was hard under my blankets, thinking about Mom growing my baby inside her. "Does Dad know?" I asked, and she shook her head.
"Thank God," she told me. "He's upset enough we have another mouth to feed. We thought I was done. You can't ever say anything to him about this, okay?"
I nodded and reached out to touch Mom. But she wasn't as excited about this as I was.
"You're going to need to pitch in," she told me. "We can't really afford another baby. I can't believe this is happening."
"I thought you liked being pregnant." I said.
"That's not the point. But we share responsibility for this mistake," Mom said, her hand on her tummy. "Just promise me you'll act normal. We have to treat the baby the same as all the rest of you kids. You know I'm going to love it just as much, okay?" She took my hand and assured me she wasn't mad, but it was a one-time mistake and it wouldn't be happening again. I didn't like that but I was too focused on her pregnancy to care too much.
After she got up and waddled out of the room, I jerked off imagining Mom's belly growing with my baby inside. I was going to get to witness it first hand.
It wasn't my imagination, Mom grew bigger and faster than she ever had before. She was eating a lot, as normal, but by six months she looked "ready to pop." I wondered if I had put twins in her, but eventually she told us she was having one girl, a big girl. It didn't take long for Mom to reach the point where she was struggling to get around the house, which I loved. Her age and the size of my child were slowing her down, and every time I saw her out of breath coming up the stairs or having trouble getting dressed I knew all the waddling and struggling was my fault. I was always there to help her off the couch or into her car, and she needed me more and more to help take care of the other kids and do household chores. I did as I was told and got a part time job to bring in more money for my baby, but I wanted to be at home with Mom as much as possible.
My bedroom is underneath my parents', so I know that Mom gets horny during her pregnancies, especially the second trimester. She definitely moans louder when she's expecting. I wonder if that's why she liked being pregnant. Usually it was exciting to me to hear her bed creaking above me, the headboard smacking against the wall, Mom's moans and gasps. I used to masturbate to those sounds. But now it just made me mad. It was my baby in Mom's belly, I should have been the one fucking her instead of Dad. I so badly wanted to take his place, making Mom scream, pounding her big fat pregnant body as hard as I could. I wanted to grab and suck those milky tits as she rode me and rub the big belly I gave her. It drove me crazy that I couldn't. I dreamt about it almost every night.
I tried hard to get back in Mom's bed. I didn't hide my interest in her pregnant body anymore, giving her compliments and openly checking her out, especially when she walked naked back to her bedroom after a shower or wore an undersized t-shirt that her bump hung out of and her big hard nipples showed through. When nobody else could hear I would tell her she looked sexy with my baby in her belly, and I would be happy to help with all her hormonal needs. I told her I could fuck her longer and harder than Dad could.
Her response was always the same. She would smile and blush and say "that's not really appropriate, is it?" Then she would change the subject. But she still made no effort to hide her body from me, and didn't call me out when I stared. She didn't stop having sex when she knew I could hear. In fact she started leaving the door cracked, knowing I wouldn't be able to resist standing in the dark hallway and watching Dad fuck her, her whole body jiggling and bouncing with each thrust. My younger self would have given anything to see pregnant Mom bent over the bed, her belly resting on the sheets, her fat ass rippling with every thrust from my dad. But now I could only think about how that should be me instead. Mom still let me cuddle up next to her on the couch and rub her belly while my daughter kicked her. She told me I was sweet when I helped her off the couch or brought her snacks. Sometimes she gave me a little wink, a reminder of the secret we kept. She wasn't mad at me for knocking her up, and eventually it seemed like she was just as excited and happy she was during any of her other pregnancies.
I thought about saying I'd tell Dad the truth if she didn't give me what I wanted. Maybe it would have worked. But I couldn't do that to my sweet mom. I loved her so much and didn't want to hurt her. In fact, I just wanted to make her feel good. One night in her seventh month she and I were the last ones awake, and I rubbed her bare belly as we sat on the couch. Mom was wearing an old T-shirt bunched up under her boobs, and I knew she wasn't wearing a bra. She almost never did, and I loved her heaving tits, stretched by eight pregnancies and seven breastfed babies so far. My hand roamed around and around her massive bump, tracing her stretch marks, marveling at how huge she was already. I brushed against her tits where they rested on her tummy. First innocently, then sneaking my hand under her shirt. Mom sighed as I made contact with the undersides of her warm, heavy boobs.
"What are you doing, honey?"
"I can't help it, Mom. You just look so hot pregnant with my baby."
She sighed again, in that impatient Mom way like when a kid is whining for something silly they want. In response I crept further under her shirt and pinched her big thick nipple. I saw her bite her lip. It felt good.
"I appreciate all your help the last few months. You've brought in money for the baby and helped me so much with the kids. So I can give you something, I guess." Mom said quietly. "I'm not going to touch you, and you can't go in my pants. But you can look at me and play with yourself."
I smiled. It was better than nothing.
"Just be quiet, I don't want anyone to hear." Mom lifted her T-shirt and let her giant boobs, which soon would be feeding my daughter, fall out. They sat on top of her belly, the areolas huge and dark. I was drooling as I grabbed the nearest one and took my dick out with my other hand.
I wanted to make it last but I was already close to cumming. Mom smiled gently, seeming nervous and embarrassed but wanting to encourage me. She acted like she wasn't looking at my dick but she kept sneaking peeks as I jerked faster and faster, breathing heavily, groping her tit and staring at her belly. The belly I grew in. The belly I watched swell over and over again my whole life. Now my own child was growing in there, bigger every day. I had planted her in my mother's womb, and Mom would keep expanding until the day came and she had to push my baby out.
My head swam with these thoughts and I moaned as I started to cum. Mom shushed me while my dick sprayed potent young seed everywhere. "Not on my clothes!" She whispered, but it was too late. My cum mostly landed on me but some got on her pajama pants and her belly. She wasn't happy but she kissed my cheek as I panted she said she hoped it felt good. Then she took the rest of her clothes off and waddled to the shower.
This became a little tradition with us. Whenever we managed to be left alone, which wasn't often with seven other kids and my dad in the house, Mom would strip topless or naked in the living room (she worried my dad would hear from above if we did it in my room) and let me masturbate. I tried to take things farther, moving a hand into her pants or trying to put her hand on my dick, but she would gently shut me down. I would feel bad afterwards, wanting her to get turned on and desire me the same way I desired her. But she seemed to just be doing it to make me happy.
Meanwhile, the baby continued to grow and so did Mom, getting bigger and bigger and bigger with my baby. Some women only put on weight in their belly when they're pregnant but Mom grew all over. It was obvious she was having a baby, but she got big everywhere from her face to her butt to her legs. The constant snacking didn't help. Mom acted like she was eating for three or four. She got so wide she took up two cushions on the couch, and those cushions are still crushed. By eight months she didn't fit in anything but loose fitting muumuu type dresses. That's what she wore when she left the house, but she tried to stay home as much as possible. Around the house she wore t-shirts, pajama pants or gym shorts, or more and more often nothing at all. As the summer got closer it was hot inside, and we didn't have air conditioning. Mom felt most comfortable naked and most of my siblings were too young to be embarrassed by it. After all, they were used to her going nude while pregnant. It was the miracle of life. But to me it was torture. I could only stare at my big beautiful mother, full of my lovechild, until we got to be alone.
One night as Mom approached nine months Dad was out late drinking with his buddies and Mom gave my siblings an early bedtime. When they were all asleep she ushered me into her bedroom. I usually had to beg and whine for her to let me masturbate to her, but tonight she started it. Her hormones must have gotten to her. She took off her skimpy clothes, showing off her enormous body as she got closer to full term. Her bump hung down so low it hid her pussy and her tits were low and heavy, laying on her bump. Mom's belly looked like a beach ball, bigger and rounder than I had ever seen it. She had stretch marks everywhere and her deep bellybutton was pulled flat. As soon as she had her clothes off I took my dick out and started rubbing it. Mom couldn't stand for long so she laid down on the bed and let me jerk off over her. She watched silently as I grunted and groaned, my hard dick just inches from her bloated belly. She spread her legs and I could see her pussy, with its thick hair and floppy lips. I had came from there, eighteen years ago. And soon my daughter would be pushed out of there. I wanted so badly to go back inside, at least one time before Mom gave birth. I thought maybe she was inviting me and I climbed on the bed. I got close enough for my cock head to touch her opening and tell that it was wet and warm and I groaned when Mom told me to stop.
"Just watch." She reached around her baby-filled belly and touched herself while I touched myself. We stared at each other, masturbating to each other. I watched, hypnotized, as my mom's wide hips rolled and her thighs jiggled, her breasts rising and falling with her breaths. She rubbed her clit with two fingers and the sound and smell of her wet pussy filled the bedroom. She moaned quietly and right in front of my eyes I saw her belly move as my baby kicked inside. That's when I lost it. I cried out and shot a huge load all over Mom's pregnant belly, her thighs, and her pussy. When my cum hit her she started to cum too. Her red face as she panted and moaned was unforgettable. We stayed like that for a few minutes, recovering in silence. Then Mom asked me to help her up. I grunted as we pulled her heavy body upright, then she waddled to the bathroom with my cum all over her and took a shower. After that she went right to bed. We didn't talk about it.
I thought that might happen again but it didn't. We were alone maybe once or twice over the next few weeks but she wouldn't even let me jerk off for her. She entered her ninth month and the happy sunny attitude she'd had for most of the pregnancy wore off. She had a growth spurt and her belly went from looking like a beach ball to looking like an overripe watermelon. She got cranky and was practically unable to get out of bed. I had to take some time off work to take care of my siblings since Mom couldn't do it. When she did get up she wouldn't put clothes on. She would just shuffle around complaining about her back and her hips and her feet. Instead of winking at me she would shoot me dirty looks. It was my fault she was so huge and uncomfortable. She hadn't planned on having a baby at 45 (her birthday had passed) but I had put one in her. This was her hardest pregnancy by far because of her weight and size, and I wondered if the incest had something to do with how big the baby was.
Her milk was coming in. I knew because she hardly ever wore a top and I would see bright drips of milk against her dark dark nipples. Sometimes they would spill over and run down her baby bump and I would have to go to my room and masturbate. I wanted to suck those tits and drink that milk. But Mom would barely look at me.
One morning her attitude changed. She knocked on my door and came in dressed in her biggest muumuu, ready to go out. She asked if I wanted to drive her to her doctor's appointment. My whole life I had been curious about pregnancy and asked Mom endless questions. When I was little I would ask to go to the doctor with her and see what happened. I wanted to see her weighed and measured, her big belly scanned to see the baby inside. Finally it was going to happen. I had to hold Mom's hand every step of the way to the car, and she barely fit inside. The car sank to one side because of her weight. We didn't talk as we drove to the doctor's office but Mom held my hand. I felt like she was sorry for the way she acted towards me.
We waited in the waiting room with other pregnant women, and Mom was the biggest one by far. She didn't even fit in the regular chairs, she had to sit on the couch. When her name was called I helped her up. People stared as she waddled back to the exam room.
Mom told her doctor that I was the man of the house today while my dad was gone, and I'd been nice enough to take her to the appointment. The doctor smiled and told me I was a good son. I stepped outside with the doctor while Mom changed into the paper gown, even though I wished I could stay behind to help her strip. When we went back in the room Mom laughed. The hospital gown wasn't anywhere near big enough for her. It only went halfway around her body, and you could see a whole side of her naked skin. She held a hand over her exposed boob. The doctor asked if she wanted me to leave and she said no, it wasn't anything I hadn't seen before.
So I watched intently as Mom stepped on the scale, one of her tits hanging out, her belly poking out from under the flimsy gown. The doctor told her she'd put on another eight pounds over the last week and needed to slow down. He was already worried about her size. This was a high risk pregnancy, he explained to me as he wrote in his chart, because of Mom's age and weight, but she had stayed mostly healthy and the baby was growing like a weed. This was Mom's last appointment, her due date was next week. The doctor said her last few births had been easy and fast, but he worried about how big this baby was.
I helped Mom get up on the table and I stared as she hiked up the gown and exposed the lower half of her body. Her belly looked even bigger here in the doctor's office under the bright lights. As the doctor measured and examined it, I just kept thinking that it was all because of me. I was the reason Mom was so big she could barely move. I was the reason I would have one more little sister. I was the reason for all those stretch marks. The doctor said everything looked good and the baby was head down, ready for birth. My daughter. My daughter in my mother's womb. I was hard as a rock as the doctor lubed up Mom's belly for the sonogram. She turned and winked at me when the doctor wasn't looking. She knew how much I liked this. I was amazed when the doctor put the wand on Mom's belly and an image of my baby came up on the screen, big and healthy and ready for Mom to push her out. She was squirming around in there and Mom groaned.
"She's still kicking like crazy even though she's out of room. But she still isn't as bad as her big brother was." Mom pointed at me. "That's right mister, you kicked me the most out of any baby. It hurt so much! And you were two weeks late to make matters worse!"
I blushed and laughed. I imagined what Mom would look like if she had the baby inside her another two weeks. "Do you think this baby will be late too?" I asked the doctor.
"We're hoping for right on time." He said. "If she gets any bigger we might have to do a c-section."
Mom shook her head. She'd had all her babies naturally. "She's coming this week, I can feel it. I can't get any bigger, she'll just have to go out." Mom rubbed her shiny belly. I was aching in my pants.
The doctor took a couple of sonogram pictures and left the room to go print them. When he was gone Mom smiled at me and invited me to come feel her belly. I rubbed all over her slick shiny bump and told her I wanted to rub my dick on it. I had my hand on my belt and Mom told me to stop. But I got another minute or two to rub that nine month belly, so full of my daughter.
"Are you ready to be a daddy?" Mom whispered. I felt dizzy thinking about that and she laughed. I had mostly been thinking about my own sexual excitement about knocking Mom up but I was also excited to have a daughter, even if it was a secret. I already loved the baby in Mom's belly. I would always know we had that special connection even if I had to act like I was just her big brother. I wondered if she would look like me.
Soon the doctor came back and teased my mom about how he hoped this was the last appointment and the last baby. He told me Mom had promised each of her last three babies were the last one.
"I can't help it. I guess I'm just made to have babies." Mom laughed as she got dressed again.
I was so horny after that and Mom knew it. Dad had stayed home with the younger kids, usually my job, and when we got back there was nobody there. He left a note saying he'd taken them all out for ice cream.
"Mom, can we go to your room?" I whined, still painfully hard.
"You were a good boy, helping me at the doctor's." She kissed my lips and had me help her up the stairs. We didn't even close the door to her room before I got my hard dick out. I needed release so badly. Mom took her muumuu off and laid down on the bed. I started jerking off in front of her just like last time, my dick pointed at that belly that was even bigger than last month. But Mom lifted her head off the pillow and looked up at me past her humongous stomach and swollen boobs.
"Do you want to go inside?" She asked.
"Yes!" My heart was hammering.
"Okay, then be quick. Before everyone comes home. And don't crush my tummy." She spread her legs wide. I stared at her wet pussy then climbed up on the bed and plunged my dick into it. It was heaven. Hotter and wetter than I remembered. I made sure not to rest my weight on Mom's very full belly, but I was still pressed up against it and it made me even more excited. Mom smiled up at me gently, happy I was feeling so good.
"Don't go too hard, okay, honey?" I nodded and started thrusting into her. The bed creaked and groaned under our weight and the headboard slammed against the wall, just like when Dad was fucking her. Mom moaned and closed her eyes. She held on to her boobs so they wouldn't bounce too much, but they still flopped back and forth with each thrust. I saw milk leaking out, dripping between her fingers. Her tits were so full I could see the veins under her skin. There was a slapping sound each time my flat stomach slapped against Mom's pregnant belly. My baby was inside, I reminded myself. I had put her there just like this, by fucking my own mother. After a few minutes Mom seemed to be in pain.
"Are you OK?"
"Yes, honey, it's just that everything is uncomfortable at nine months. Just finish up when you can."
I grabbed hold of Mom's belly and pushed myself as deep in her pussy as I could go. I felt the cum bubbling up and I thrusted faster and harder until I was almost screaming, emptying my full balls into my mother's nine month pregnant body. It was the best orgasm I ever had. When I finally pulled out cum immediately leaked out of her. I had filled her up.
"Was that good, honey?" Mom asked, relaxing a bit now that I was off of her. I just nodded.
"Alright, when you're ready help me up. We need to change these sheets."
That was the only time I got to have sex with Mom while she was pregnant. Her mood changed again after her due date passed, getting cranky again. A week passed with no signs of labor. The doctor told her he'd induce her if she made it to 42 weeks. She was fully confined to bed by this point. Dad and I had to bring her all her meals and help her to the bathroom. Mom was so uncomfortable she would cry. There wasn't much she could do to get labor going while she was stuck in bed. She just had to wait. Every day I marveled at how big she was. It really looked like she was having twins or even triplets. Her belly reached down to her knees. Her tits were the size of her head and always leaking. She could barely breathe or sleep. I saw her clutching her belly and shaking it, telling my baby to get out already. I felt guilty at what I'd done to Mom, but I was also so turned on that I had to masturbate after every time I saw her.
We were two days away from Mom having to get induced. I was asleep, probably dreaming of fucking her again. Then I woke up and Mom was standing in the dark in my room. I don't know how she managed to get out of bed on her own. She could barely even stand. She looked sweaty and tired.
"Mom, what's wrong?"
She waddled closer to me, taking tiny little steps. "My water broke. You're going to be a daddy." She whispered. Then she pointed down to her nightgown, which was soaked from the waist down.
I gasped and started to get out of bed. Mom laughed. "No, we don't have to run to the hospital. We have to wait until the contractions are closer. It might take a few hours."
I settled back into bed and she could see my erection through my shorts.
"Can I take it out?" I asked.
"Well, it's not going inside me. But if you want to look, this is the last time you're going to see your old mom pregnant." She pulled the nightgown off and stood there naked over my bed. She looked like a Hollywood special effect. Her belly was so big it looked fake. My baby had made her bigger than she had ever been before. I took my dick out and started masturbating.
Mom could only move slowly. She wiggled her belly in my face and held her swollen breasts, jiggling them for me. Then she rubbed her belly all over. She couldn't even reach all of it. "I can't believe this is happening. I'm going to have your baby." A contraction started. Mom huffed and puffed through it and had to pace around. Seeing her in labor pushed me over the edge. I groaned and shot my load all over myself. The same sperm that had made my mother pregnant nine months and two weeks ago, right here in this bed.
I caught my breath and got up, my still hard and sticky cock poking Mom as I held her hand and helped her keep upright through the contraction. I stared lustfully as everything on her soft round body jiggled with her swaying movements but I didn't try anything else. I had to be here for Mom, especially because this was my fault. One night of drunken fun had led to this. Mom's 45 year old body was getting ready to push out my baby. I didn't know how she was going to do it. She looked exhausted already. I worried that she was too old. I helped her through her contractions until the sun came up. Sometimes she wanted to walk around. Sometimes she wanted to lay in bed or bend over. The pains were getting closer together. I put some clothes on before anybody else could wake up.
Once morning came the house was full of excitement. Dad took over helping my mom and I had to deal with my excited siblings, making them breakfast while they babbled about the new baby. They crowded around Mom and rubbed her belly between contractions. She was still naked. I wondered if anyone noticed the dried cum I had accidentally smeared on her. The day went on and Dad timed Mom's contractions and called the doctor. At one point when nobody was looking Mom gave me a secretive smile. Only we knew the secret in her belly. My sister was actually my daughter. I had fathered a child inside my mom, and she and I would have to live with that forever.
When the contractions got close enough together Dad piled the whole family into the car. He held Mom's hand and she moaned with pain as we rushed to the hospital. She gave me one last look as we got to the entrance. I had to park the car while Dad pulled Mom out of the car and got a special wheelchair for her. None of us kids were allowed in the delivery room. I watched out the car window as Dad wheeled Mom inside, her gigantic laboring belly full of her son's baby on full display since all she was wearing was a tiny t-shirt and shorts.
The hours went by slowly as I sat in the waiting room and watched my little brothers and sisters. I had to keep them occupied and fed while Dad texted me updates. I had done this before, when my youngest brother was born, but this was different. My child was being born behind those doors. I was so nervous. And this was not a fast easy labor the way the last few babies had been. I worried that the baby would get stuck or something would happen to her or Mom. I worried it would be my fault. I should have never gotten into Mom's bed.
My siblings fell asleep, and eventually so did I. It was the next morning by the time Dad came out and invited us all into the delivery room, reminding the little ones to be quiet. I stood in the back of the group as we came in.
Mom was sitting in bed, looking totally spent. She had barely slept in three days and she looked closer to 55 than 45. But she was smiling wide and holding a very large sleeping baby to her breasts. My daughter was almost eleven pounds, the biggest baby Mom ever had by far. It had looked like they might have to give her a c-section for a while but she had managed to push my baby out the natural way. I was silent as my siblings chattered and cooed over the baby, and Mom offered to let me hold her first. My head spun as I took her in my arms. I was a father.
The rest of the day was kind of a blur but I know at some point Mom whispered "thank you" in my ear.
A few days later Mom and the baby came home. The next few months weren't easy. We all knew the drill. The baby was loud, nobody got any sleep, the house was a mess. Friends and neighbors and family visited to meet Mom's last baby. When we didn't have visitors Mom didn't bother putting on clothes, needing to nurse on demand. Her already enormous tits grew even bigger with her milk really in, and every day I watched her feed my baby with them. It was rare for the two of us to get a moment alone, but occasionally it would happen. And that's when Mom would make my dreams come true. She would let me lay in her lap, my head against her soft belly that still looked six or seven months pregnant, and suckle her huge brown nipples until her milk flowed. She makes way too much for one baby, and my daughter is happy to share. Sometimes Mom even feeds both of us at the same time.
When we know we have privacy for a little bit Mom will let me take my dick out while I nurse and she or I will rub it until I cum. It never takes long, I'm so turned on by drinking Mom's milk and knowing I'm the reason she has it again. Our relationship has changed forever. I hope we'll have sex again when she's healed up. I dream about giving her another baby, but she insists this was her last one and she's too old now. We'll see.
Nobody was surprised that Mom was pregnant again. Even though most people would think she was too old to have any more kids. Her last baby, my little brother, was born three years ago when she was 41, and she swore that was her last one even though she loved being pregnant. I'm the oldest of seven, soon to be eight. My mom doesn't believe in birth control and was with child pretty much my whole life. I don't know if that's why I have a fetish for pregnant women but I always liked looking at Mom while her belly swelled up. Eight pregnancies have taken their toll on her body. I've seen pictures of her before she had kids and she looked almost skinny, but with each baby she got bigger and rounder and never dropped much of the weight after. You could probably describe her as an SSBBW. I already thought she was hot with her big sagging tits, huge ass, and thick thighs, but seeing her pregnant was something else. I have many great memories of cuddling up with her on the couch, feeling my next little sibling squirming around in her massive belly, and as I got older I realized I was sexually interested in both pregnant women and my mother.
This was at best an open secret between me and my mom. I had never said anything about it to her but she knew how obsessed I got with her boobs and belly whenever she had a bun in her oven, and she had once seen my internet history full of searches for pregnant porn. She's not a shy woman. She let me cuddle her, rub her bare belly and kiss it, lay with my head on her chest. I got to see her naked in her third trimester because she was so big she couldn't cover herself with a towel after a shower. She saw the way I looked at her and made no effort to cover up. When she sat on the sofa with her top open on her belly feeling my sibling move I got so horny a few times that I left the room and even went into the bathroom to have a wank to it. I wonder if she knew what was happening. There were a lot of us in a small space and privacy wasn't always possible.
So her previous pregnancies were already exciting to me, but this one is different. Not just because Mom is well into middle age, with her hair going gray and wrinkles forming around her mouth and forehead. Not just because she's bigger than ever, having put on maybe fifty pounds in the last nine months. The thing is, the baby girl in Mom's womb wasn't put there by my dad. I'm her father.
Being the oldest of so many kids, I got used to helping my mom around the house, especially when Dad wasn't there. Even as a little kid I liked taking this role as the "man of the house." Last year I was tasked with helping Mom plan my youngest brother's birthday party while my dad was away on business. I think I did a great job, and everyone had fun, especially all the kids' parents with the booze I provided. Mom was able to relax while I took care of everything, and she ended up getting quite drunk. I was tipsy too, and once the guests were gone and my siblings were in bed Mom hugged me and praised me and kissed me right on the lips. We'd always been very affectionate with one another, and not shy about our bodies, so that wasn't the biggest surprise, nor was the way she stripped in front of me while preparing for bed. But when I got in bed beside her, just as naked, things changed. She teased me at first, making fun of my hard-on, asking why I was hot for my fat old mom. I just kept telling her she was beautiful and reaching out to touch her and before we could think better of it I was on top of her, sinking into all that soft lovely flesh. I wish my memory of that night was clearer, given how important it became. I remember Mom's big fat titties in my face, bouncing under me as I thrusted. I remember her groaning like a stuck pig and me having to cover her mouth because I was worried my brothers and sisters would hear her. I remember how hot and wet her pussy was, even if it wasn't very tight, and the excitement of finally getting inside her after years of lusting after her making it so I didn't last long. I remember how amazing it felt to cum in my mother, and how immediately I wanted to do it again.
I tried to talk to her about it the day after and she pretended like it didn't happen. I was devastated that I'd achieved my dream but would never get to do it again. My dad came home from business, my mom told him about the great party I'd thrown, and not long after I heard them fucking upstairs. I burned with jealousy.
Mom has been pregnant so many times we all know the telltale signs. She doesn't get morning sickness. Maybe she did with the first one or two babies, but her body is so used to pregnancy it doesn't seem to have that effect on her. What happens first is she gets really tired for a few weeks. She's a busy woman, with so many kids and a husband to take care of, but she doesn't fall asleep snoring on the couch watching TV unless she's knocked up, or take naps during the day. So when she started dozing off a lot late last year I got suspicious. My siblings would make jokes about it; even they were old enough to know what it meant. I was shocked. I assumed Mom was far too old to have another baby, and hadn't even considered that possibility after we'd fucked. But the next sign came when she got her energy back and started eating everything in the house. The craving stage would start at the end of her first trimester and not really let up until the very end. By New Year's Mom's belly was noticeably swollen, earlier than in any of her other pregnancies, I later found out. We just had to wait for the announcement.
Nobody was surprised when Mom and Dad sat us all down and explained that we would have a new baby brother or sister by the summer. My brothers and sisters congratulated her and swarmed her and rubbed her already quite sizable tummy, and Mom seemed happy enough even if she looked far too old to be having a baby. The surprise came when, later that night, Mom knocked on my door and sat on my bed, giving me a little talk in private.
"The baby's yours," she whispered, the first time she acknowledged that we'd had sex all those months ago. "We weren't careful." She didn't seem happy about it now.
I had been wondering if this was the case but it still shocked me to hear her say it. A pit opened in my stomach. I couldn't believe I'd knocked up my own mother. I felt ill but also excited. I was hard under my blankets, thinking about Mom growing my baby inside her. "Does Dad know?" I asked, and she shook her head.
"Thank God," she told me. "He's upset enough we have another mouth to feed. We thought I was done. You can't ever say anything to him about this, okay?"
I nodded and reached out to touch Mom. But she wasn't as excited about this as I was.
"You're going to need to pitch in," she told me. "We can't really afford another baby. I can't believe this is happening."
"I thought you liked being pregnant." I said.
"That's not the point. But we share responsibility for this mistake," Mom said, her hand on her tummy. "Just promise me you'll act normal. We have to treat the baby the same as all the rest of you kids. You know I'm going to love it just as much, okay?" She took my hand and assured me she wasn't mad, but it was a one-time mistake and it wouldn't be happening again. I didn't like that but I was too focused on her pregnancy to care too much.
After she got up and waddled out of the room, I jerked off imagining Mom's belly growing with my baby inside. I was going to get to witness it first hand.
It wasn't my imagination, Mom grew bigger and faster than she ever had before. She was eating a lot, as normal, but by six months she looked "ready to pop." I wondered if I had put twins in her, but eventually she told us she was having one girl, a big girl. It didn't take long for Mom to reach the point where she was struggling to get around the house, which I loved. Her age and the size of my child were slowing her down, and every time I saw her out of breath coming up the stairs or having trouble getting dressed I knew all the waddling and struggling was my fault. I was always there to help her off the couch or into her car, and she needed me more and more to help take care of the other kids and do household chores. I did as I was told and got a part time job to bring in more money for my baby, but I wanted to be at home with Mom as much as possible.
My bedroom is underneath my parents', so I know that Mom gets horny during her pregnancies, especially the second trimester. She definitely moans louder when she's expecting. I wonder if that's why she liked being pregnant. Usually it was exciting to me to hear her bed creaking above me, the headboard smacking against the wall, Mom's moans and gasps. I used to masturbate to those sounds. But now it just made me mad. It was my baby in Mom's belly, I should have been the one fucking her instead of Dad. I so badly wanted to take his place, making Mom scream, pounding her big fat pregnant body as hard as I could. I wanted to grab and suck those milky tits as she rode me and rub the big belly I gave her. It drove me crazy that I couldn't. I dreamt about it almost every night.
I tried hard to get back in Mom's bed. I didn't hide my interest in her pregnant body anymore, giving her compliments and openly checking her out, especially when she walked naked back to her bedroom after a shower or wore an undersized t-shirt that her bump hung out of and her big hard nipples showed through. When nobody else could hear I would tell her she looked sexy with my baby in her belly, and I would be happy to help with all her hormonal needs. I told her I could fuck her longer and harder than Dad could.
Her response was always the same. She would smile and blush and say "that's not really appropriate, is it?" Then she would change the subject. But she still made no effort to hide her body from me, and didn't call me out when I stared. She didn't stop having sex when she knew I could hear. In fact she started leaving the door cracked, knowing I wouldn't be able to resist standing in the dark hallway and watching Dad fuck her, her whole body jiggling and bouncing with each thrust. My younger self would have given anything to see pregnant Mom bent over the bed, her belly resting on the sheets, her fat ass rippling with every thrust from my dad. But now I could only think about how that should be me instead. Mom still let me cuddle up next to her on the couch and rub her belly while my daughter kicked her. She told me I was sweet when I helped her off the couch or brought her snacks. Sometimes she gave me a little wink, a reminder of the secret we kept. She wasn't mad at me for knocking her up, and eventually it seemed like she was just as excited and happy she was during any of her other pregnancies.
I thought about saying I'd tell Dad the truth if she didn't give me what I wanted. Maybe it would have worked. But I couldn't do that to my sweet mom. I loved her so much and didn't want to hurt her. In fact, I just wanted to make her feel good. One night in her seventh month she and I were the last ones awake, and I rubbed her bare belly as we sat on the couch. Mom was wearing an old T-shirt bunched up under her boobs, and I knew she wasn't wearing a bra. She almost never did, and I loved her heaving tits, stretched by eight pregnancies and seven breastfed babies so far. My hand roamed around and around her massive bump, tracing her stretch marks, marveling at how huge she was already. I brushed against her tits where they rested on her tummy. First innocently, then sneaking my hand under her shirt. Mom sighed as I made contact with the undersides of her warm, heavy boobs.
"What are you doing, honey?"
"I can't help it, Mom. You just look so hot pregnant with my baby."
She sighed again, in that impatient Mom way like when a kid is whining for something silly they want. In response I crept further under her shirt and pinched her big thick nipple. I saw her bite her lip. It felt good.
"I appreciate all your help the last few months. You've brought in money for the baby and helped me so much with the kids. So I can give you something, I guess." Mom said quietly. "I'm not going to touch you, and you can't go in my pants. But you can look at me and play with yourself."
I smiled. It was better than nothing.
"Just be quiet, I don't want anyone to hear." Mom lifted her T-shirt and let her giant boobs, which soon would be feeding my daughter, fall out. They sat on top of her belly, the areolas huge and dark. I was drooling as I grabbed the nearest one and took my dick out with my other hand.
I wanted to make it last but I was already close to cumming. Mom smiled gently, seeming nervous and embarrassed but wanting to encourage me. She acted like she wasn't looking at my dick but she kept sneaking peeks as I jerked faster and faster, breathing heavily, groping her tit and staring at her belly. The belly I grew in. The belly I watched swell over and over again my whole life. Now my own child was growing in there, bigger every day. I had planted her in my mother's womb, and Mom would keep expanding until the day came and she had to push my baby out.
My head swam with these thoughts and I moaned as I started to cum. Mom shushed me while my dick sprayed potent young seed everywhere. "Not on my clothes!" She whispered, but it was too late. My cum mostly landed on me but some got on her pajama pants and her belly. She wasn't happy but she kissed my cheek as I panted she said she hoped it felt good. Then she took the rest of her clothes off and waddled to the shower.
This became a little tradition with us. Whenever we managed to be left alone, which wasn't often with seven other kids and my dad in the house, Mom would strip topless or naked in the living room (she worried my dad would hear from above if we did it in my room) and let me masturbate. I tried to take things farther, moving a hand into her pants or trying to put her hand on my dick, but she would gently shut me down. I would feel bad afterwards, wanting her to get turned on and desire me the same way I desired her. But she seemed to just be doing it to make me happy.
Meanwhile, the baby continued to grow and so did Mom, getting bigger and bigger and bigger with my baby. Some women only put on weight in their belly when they're pregnant but Mom grew all over. It was obvious she was having a baby, but she got big everywhere from her face to her butt to her legs. The constant snacking didn't help. Mom acted like she was eating for three or four. She got so wide she took up two cushions on the couch, and those cushions are still crushed. By eight months she didn't fit in anything but loose fitting muumuu type dresses. That's what she wore when she left the house, but she tried to stay home as much as possible. Around the house she wore t-shirts, pajama pants or gym shorts, or more and more often nothing at all. As the summer got closer it was hot inside, and we didn't have air conditioning. Mom felt most comfortable naked and most of my siblings were too young to be embarrassed by it. After all, they were used to her going nude while pregnant. It was the miracle of life. But to me it was torture. I could only stare at my big beautiful mother, full of my lovechild, until we got to be alone.
One night as Mom approached nine months Dad was out late drinking with his buddies and Mom gave my siblings an early bedtime. When they were all asleep she ushered me into her bedroom. I usually had to beg and whine for her to let me masturbate to her, but tonight she started it. Her hormones must have gotten to her. She took off her skimpy clothes, showing off her enormous body as she got closer to full term. Her bump hung down so low it hid her pussy and her tits were low and heavy, laying on her bump. Mom's belly looked like a beach ball, bigger and rounder than I had ever seen it. She had stretch marks everywhere and her deep bellybutton was pulled flat. As soon as she had her clothes off I took my dick out and started rubbing it. Mom couldn't stand for long so she laid down on the bed and let me jerk off over her. She watched silently as I grunted and groaned, my hard dick just inches from her bloated belly. She spread her legs and I could see her pussy, with its thick hair and floppy lips. I had came from there, eighteen years ago. And soon my daughter would be pushed out of there. I wanted so badly to go back inside, at least one time before Mom gave birth. I thought maybe she was inviting me and I climbed on the bed. I got close enough for my cock head to touch her opening and tell that it was wet and warm and I groaned when Mom told me to stop.
"Just watch." She reached around her baby-filled belly and touched herself while I touched myself. We stared at each other, masturbating to each other. I watched, hypnotized, as my mom's wide hips rolled and her thighs jiggled, her breasts rising and falling with her breaths. She rubbed her clit with two fingers and the sound and smell of her wet pussy filled the bedroom. She moaned quietly and right in front of my eyes I saw her belly move as my baby kicked inside. That's when I lost it. I cried out and shot a huge load all over Mom's pregnant belly, her thighs, and her pussy. When my cum hit her she started to cum too. Her red face as she panted and moaned was unforgettable. We stayed like that for a few minutes, recovering in silence. Then Mom asked me to help her up. I grunted as we pulled her heavy body upright, then she waddled to the bathroom with my cum all over her and took a shower. After that she went right to bed. We didn't talk about it.
I thought that might happen again but it didn't. We were alone maybe once or twice over the next few weeks but she wouldn't even let me jerk off for her. She entered her ninth month and the happy sunny attitude she'd had for most of the pregnancy wore off. She had a growth spurt and her belly went from looking like a beach ball to looking like an overripe watermelon. She got cranky and was practically unable to get out of bed. I had to take some time off work to take care of my siblings since Mom couldn't do it. When she did get up she wouldn't put clothes on. She would just shuffle around complaining about her back and her hips and her feet. Instead of winking at me she would shoot me dirty looks. It was my fault she was so huge and uncomfortable. She hadn't planned on having a baby at 45 (her birthday had passed) but I had put one in her. This was her hardest pregnancy by far because of her weight and size, and I wondered if the incest had something to do with how big the baby was.
Her milk was coming in. I knew because she hardly ever wore a top and I would see bright drips of milk against her dark dark nipples. Sometimes they would spill over and run down her baby bump and I would have to go to my room and masturbate. I wanted to suck those tits and drink that milk. But Mom would barely look at me.
One morning her attitude changed. She knocked on my door and came in dressed in her biggest muumuu, ready to go out. She asked if I wanted to drive her to her doctor's appointment. My whole life I had been curious about pregnancy and asked Mom endless questions. When I was little I would ask to go to the doctor with her and see what happened. I wanted to see her weighed and measured, her big belly scanned to see the baby inside. Finally it was going to happen. I had to hold Mom's hand every step of the way to the car, and she barely fit inside. The car sank to one side because of her weight. We didn't talk as we drove to the doctor's office but Mom held my hand. I felt like she was sorry for the way she acted towards me.
We waited in the waiting room with other pregnant women, and Mom was the biggest one by far. She didn't even fit in the regular chairs, she had to sit on the couch. When her name was called I helped her up. People stared as she waddled back to the exam room.
Mom told her doctor that I was the man of the house today while my dad was gone, and I'd been nice enough to take her to the appointment. The doctor smiled and told me I was a good son. I stepped outside with the doctor while Mom changed into the paper gown, even though I wished I could stay behind to help her strip. When we went back in the room Mom laughed. The hospital gown wasn't anywhere near big enough for her. It only went halfway around her body, and you could see a whole side of her naked skin. She held a hand over her exposed boob. The doctor asked if she wanted me to leave and she said no, it wasn't anything I hadn't seen before.
So I watched intently as Mom stepped on the scale, one of her tits hanging out, her belly poking out from under the flimsy gown. The doctor told her she'd put on another eight pounds over the last week and needed to slow down. He was already worried about her size. This was a high risk pregnancy, he explained to me as he wrote in his chart, because of Mom's age and weight, but she had stayed mostly healthy and the baby was growing like a weed. This was Mom's last appointment, her due date was next week. The doctor said her last few births had been easy and fast, but he worried about how big this baby was.
I helped Mom get up on the table and I stared as she hiked up the gown and exposed the lower half of her body. Her belly looked even bigger here in the doctor's office under the bright lights. As the doctor measured and examined it, I just kept thinking that it was all because of me. I was the reason Mom was so big she could barely move. I was the reason I would have one more little sister. I was the reason for all those stretch marks. The doctor said everything looked good and the baby was head down, ready for birth. My daughter. My daughter in my mother's womb. I was hard as a rock as the doctor lubed up Mom's belly for the sonogram. She turned and winked at me when the doctor wasn't looking. She knew how much I liked this. I was amazed when the doctor put the wand on Mom's belly and an image of my baby came up on the screen, big and healthy and ready for Mom to push her out. She was squirming around in there and Mom groaned.
"She's still kicking like crazy even though she's out of room. But she still isn't as bad as her big brother was." Mom pointed at me. "That's right mister, you kicked me the most out of any baby. It hurt so much! And you were two weeks late to make matters worse!"
I blushed and laughed. I imagined what Mom would look like if she had the baby inside her another two weeks. "Do you think this baby will be late too?" I asked the doctor.
"We're hoping for right on time." He said. "If she gets any bigger we might have to do a c-section."
Mom shook her head. She'd had all her babies naturally. "She's coming this week, I can feel it. I can't get any bigger, she'll just have to go out." Mom rubbed her shiny belly. I was aching in my pants.
The doctor took a couple of sonogram pictures and left the room to go print them. When he was gone Mom smiled at me and invited me to come feel her belly. I rubbed all over her slick shiny bump and told her I wanted to rub my dick on it. I had my hand on my belt and Mom told me to stop. But I got another minute or two to rub that nine month belly, so full of my daughter.
"Are you ready to be a daddy?" Mom whispered. I felt dizzy thinking about that and she laughed. I had mostly been thinking about my own sexual excitement about knocking Mom up but I was also excited to have a daughter, even if it was a secret. I already loved the baby in Mom's belly. I would always know we had that special connection even if I had to act like I was just her big brother. I wondered if she would look like me.
Soon the doctor came back and teased my mom about how he hoped this was the last appointment and the last baby. He told me Mom had promised each of her last three babies were the last one.
"I can't help it. I guess I'm just made to have babies." Mom laughed as she got dressed again.
I was so horny after that and Mom knew it. Dad had stayed home with the younger kids, usually my job, and when we got back there was nobody there. He left a note saying he'd taken them all out for ice cream.
"Mom, can we go to your room?" I whined, still painfully hard.
"You were a good boy, helping me at the doctor's." She kissed my lips and had me help her up the stairs. We didn't even close the door to her room before I got my hard dick out. I needed release so badly. Mom took her muumuu off and laid down on the bed. I started jerking off in front of her just like last time, my dick pointed at that belly that was even bigger than last month. But Mom lifted her head off the pillow and looked up at me past her humongous stomach and swollen boobs.
"Do you want to go inside?" She asked.
"Yes!" My heart was hammering.
"Okay, then be quick. Before everyone comes home. And don't crush my tummy." She spread her legs wide. I stared at her wet pussy then climbed up on the bed and plunged my dick into it. It was heaven. Hotter and wetter than I remembered. I made sure not to rest my weight on Mom's very full belly, but I was still pressed up against it and it made me even more excited. Mom smiled up at me gently, happy I was feeling so good.
"Don't go too hard, okay, honey?" I nodded and started thrusting into her. The bed creaked and groaned under our weight and the headboard slammed against the wall, just like when Dad was fucking her. Mom moaned and closed her eyes. She held on to her boobs so they wouldn't bounce too much, but they still flopped back and forth with each thrust. I saw milk leaking out, dripping between her fingers. Her tits were so full I could see the veins under her skin. There was a slapping sound each time my flat stomach slapped against Mom's pregnant belly. My baby was inside, I reminded myself. I had put her there just like this, by fucking my own mother. After a few minutes Mom seemed to be in pain.
"Are you OK?"
"Yes, honey, it's just that everything is uncomfortable at nine months. Just finish up when you can."
I grabbed hold of Mom's belly and pushed myself as deep in her pussy as I could go. I felt the cum bubbling up and I thrusted faster and harder until I was almost screaming, emptying my full balls into my mother's nine month pregnant body. It was the best orgasm I ever had. When I finally pulled out cum immediately leaked out of her. I had filled her up.
"Was that good, honey?" Mom asked, relaxing a bit now that I was off of her. I just nodded.
"Alright, when you're ready help me up. We need to change these sheets."
That was the only time I got to have sex with Mom while she was pregnant. Her mood changed again after her due date passed, getting cranky again. A week passed with no signs of labor. The doctor told her he'd induce her if she made it to 42 weeks. She was fully confined to bed by this point. Dad and I had to bring her all her meals and help her to the bathroom. Mom was so uncomfortable she would cry. There wasn't much she could do to get labor going while she was stuck in bed. She just had to wait. Every day I marveled at how big she was. It really looked like she was having twins or even triplets. Her belly reached down to her knees. Her tits were the size of her head and always leaking. She could barely breathe or sleep. I saw her clutching her belly and shaking it, telling my baby to get out already. I felt guilty at what I'd done to Mom, but I was also so turned on that I had to masturbate after every time I saw her.
We were two days away from Mom having to get induced. I was asleep, probably dreaming of fucking her again. Then I woke up and Mom was standing in the dark in my room. I don't know how she managed to get out of bed on her own. She could barely even stand. She looked sweaty and tired.
"Mom, what's wrong?"
She waddled closer to me, taking tiny little steps. "My water broke. You're going to be a daddy." She whispered. Then she pointed down to her nightgown, which was soaked from the waist down.
I gasped and started to get out of bed. Mom laughed. "No, we don't have to run to the hospital. We have to wait until the contractions are closer. It might take a few hours."
I settled back into bed and she could see my erection through my shorts.
"Can I take it out?" I asked.
"Well, it's not going inside me. But if you want to look, this is the last time you're going to see your old mom pregnant." She pulled the nightgown off and stood there naked over my bed. She looked like a Hollywood special effect. Her belly was so big it looked fake. My baby had made her bigger than she had ever been before. I took my dick out and started masturbating.
Mom could only move slowly. She wiggled her belly in my face and held her swollen breasts, jiggling them for me. Then she rubbed her belly all over. She couldn't even reach all of it. "I can't believe this is happening. I'm going to have your baby." A contraction started. Mom huffed and puffed through it and had to pace around. Seeing her in labor pushed me over the edge. I groaned and shot my load all over myself. The same sperm that had made my mother pregnant nine months and two weeks ago, right here in this bed.
I caught my breath and got up, my still hard and sticky cock poking Mom as I held her hand and helped her keep upright through the contraction. I stared lustfully as everything on her soft round body jiggled with her swaying movements but I didn't try anything else. I had to be here for Mom, especially because this was my fault. One night of drunken fun had led to this. Mom's 45 year old body was getting ready to push out my baby. I didn't know how she was going to do it. She looked exhausted already. I worried that she was too old. I helped her through her contractions until the sun came up. Sometimes she wanted to walk around. Sometimes she wanted to lay in bed or bend over. The pains were getting closer together. I put some clothes on before anybody else could wake up.
Once morning came the house was full of excitement. Dad took over helping my mom and I had to deal with my excited siblings, making them breakfast while they babbled about the new baby. They crowded around Mom and rubbed her belly between contractions. She was still naked. I wondered if anyone noticed the dried cum I had accidentally smeared on her. The day went on and Dad timed Mom's contractions and called the doctor. At one point when nobody was looking Mom gave me a secretive smile. Only we knew the secret in her belly. My sister was actually my daughter. I had fathered a child inside my mom, and she and I would have to live with that forever.
When the contractions got close enough together Dad piled the whole family into the car. He held Mom's hand and she moaned with pain as we rushed to the hospital. She gave me one last look as we got to the entrance. I had to park the car while Dad pulled Mom out of the car and got a special wheelchair for her. None of us kids were allowed in the delivery room. I watched out the car window as Dad wheeled Mom inside, her gigantic laboring belly full of her son's baby on full display since all she was wearing was a tiny t-shirt and shorts.
The hours went by slowly as I sat in the waiting room and watched my little brothers and sisters. I had to keep them occupied and fed while Dad texted me updates. I had done this before, when my youngest brother was born, but this was different. My child was being born behind those doors. I was so nervous. And this was not a fast easy labor the way the last few babies had been. I worried that the baby would get stuck or something would happen to her or Mom. I worried it would be my fault. I should have never gotten into Mom's bed.
My siblings fell asleep, and eventually so did I. It was the next morning by the time Dad came out and invited us all into the delivery room, reminding the little ones to be quiet. I stood in the back of the group as we came in.
Mom was sitting in bed, looking totally spent. She had barely slept in three days and she looked closer to 55 than 45. But she was smiling wide and holding a very large sleeping baby to her breasts. My daughter was almost eleven pounds, the biggest baby Mom ever had by far. It had looked like they might have to give her a c-section for a while but she had managed to push my baby out the natural way. I was silent as my siblings chattered and cooed over the baby, and Mom offered to let me hold her first. My head spun as I took her in my arms. I was a father.
The rest of the day was kind of a blur but I know at some point Mom whispered "thank you" in my ear.
A few days later Mom and the baby came home. The next few months weren't easy. We all knew the drill. The baby was loud, nobody got any sleep, the house was a mess. Friends and neighbors and family visited to meet Mom's last baby. When we didn't have visitors Mom didn't bother putting on clothes, needing to nurse on demand. Her already enormous tits grew even bigger with her milk really in, and every day I watched her feed my baby with them. It was rare for the two of us to get a moment alone, but occasionally it would happen. And that's when Mom would make my dreams come true. She would let me lay in her lap, my head against her soft belly that still looked six or seven months pregnant, and suckle her huge brown nipples until her milk flowed. She makes way too much for one baby, and my daughter is happy to share. Sometimes Mom even feeds both of us at the same time.
When we know we have privacy for a little bit Mom will let me take my dick out while I nurse and she or I will rub it until I cum. It never takes long, I'm so turned on by drinking Mom's milk and knowing I'm the reason she has it again. Our relationship has changed forever. I hope we'll have sex again when she's healed up. I dream about giving her another baby, but she insists this was her last one and she's too old now. We'll see.
