I just stared at her sitting in the dining chair that had been dragged over to the sitting area from the formal dining table.  She was laughing and smiling as she engaged in the usual family conversation.  Her hair was down and hung around her shoulders.  Her gray tank top clung tightly to her now swollen breasts and hugely protruding belly.  I have no idea how she was able to button the jean shorts, or if they even were.  You could clearly see her belly button poking through the tightly stretched material of her shirt.  Her legs spread just slightly to accommodate the almost comically large belly as she sat.  She was due in less than a week and even though she smiled her beautiful smile while talking with the family, you could still see how miserably uncomfortable she was. The baby was ready, and so was she.

Christina was my brother-in-law’s wife, but she always had my attention whenever we hung out together.  Otherwise petite and thin, she had a round little booty that I was always sure to catch a glimpse of, being careful that no one saw.  Her husband and my wife would both never forgive either of us if they ever found out some of the things we had done over the years.  My work lunches, out of town travel and late nights were almost always just excuses to catch up with Christina at the local Embassy suites or wherever that particular night took us.

“How are you doing?” I asked when we were finally alone in the kitchen after dinner.  The rest of the family was watching Sarah,, Christina’s first born, run around in the backyard.

“I’ve got to get this baby out of me soon.” Christina replied as she rubbed the massive full-term belly between us.  Looking over my shoulder at the door, I reached out and rubbed it along with her.  It was absolutely stretched to its limit and I could feel how taught her sink was under the thin tank top.

“Go to Kroger later.” I teased, smiling and using air quotes.

“Ryan  has to go into work tomorrow for a few hours and I’m going to drop Sarah  off at her little friend’s pizza party.” she smiled back.  “Your wife doesn't come back from Kentucky with her friend until like noon, right?”

“Correct. So if you drop off Sarah at 10, that gives us a few hours” 

“I’ll make sure she’s there by 9:45 to give me a head start.” Christina said as she gave me a risky little kiss.  

“Don't have this baby tonight” I joked back as i smacked her tight 
 little booty.

“I’ll try not to” she laughed back as she made her way toward the patio door to join the family.  Her perfect little ass still tight and firm as ever as she walked.

                                                       —-------
“Can you open the garage door?” the text read on my phone. “I’m two minutes away.”

We were always careful, never letting anyone know of our little rendezvous was key, which included parking her suv in the garage whenever she would visit alone.

My dick was already hard when I heard the car door shut and the garage door close.  I knew it was wrong, but neither of us could stop.  We had been fucking for over a year now, and this pregnancy certainly didnt slow things down at all.

“Ryan’s  going to be home in an hour.” she said, slamming her purse on the kitchen island as she entered.

“You ok?” I asked as I got off the couch and walked toward her.  She looked disheveled.  Her hair was in a loose ponytail, she wasn't wearing any makeup and her eyes were tired. 

“Yeah” she replied, sighing deeply.  One hand was on her hip and the other was rubbing the side of her big belly.  Her palm pushed hard into the tight skin as she rubbed up and down.  “I was up half the night with Braxton Hicks and this baby tumbling around like an acrobat.  That’s the last time I have anything spicy this pregnancy.”

My hand rubbed her belly with her as I stood in front of her.  She was again wearing those tight denim shorts from last night and another tank top, this one white.  She had also taken her bra off in the car.  Her once small and perky little tits were now swollen by at least two bra sizes and I could see her dark little nipples poking through the tight shirt.

“Things are better now though” she said, putting her arms around my neck, pulling me closer. The belly pushed hard into me between us.

My hand made its way to her tits as we kissed, her hands still locked around my neck.  She leaned harder into me and stood on her tippy toes as she forced her tongue into my mouth.  She was in an aggressive mood.  I like that sometimes she just wanted to get down to business and not fuck around.

“Shit!” I whispered as her tank top grew damp.  Like the belly, her perky little tits were also now at their limit and the simple pressure from my squeeze as we kissed caused milk to flood out almost immediately. 

Christina laughed out loud, her hard cute little laugh.  “Yeah, I didnt pump this morning so they would be extra full for you.”  She unclasped one hand from around my neck and grabbed the other tit, giving it a little squeeze.  Another damp spot appeared on the tank-top around her nipple.

“Fuck me!” I said under my breath in disbelief.  “That’s new, and I fucking love it!”  I grabbed her tight little ass and pulled her even harder into me.

“Oh I figured you would” Christina giggled.

“Go to the bedroom” I ordered.

Doing as instructed, she turned away from me and walked across the livingroom toward the master bedroom.  My eyes were glued to her firm little ass.  She had always been slightly tall, very petite and her ass was always just a tiny bit too big for her frame.  I loved that too, and she knew it.  I watched the tight denim pull at those perfect cheeks as she continued toward the doorway.

“Sit” I demanded as we made it to the edge of the bed.

She did as instructed and I knelt to take off her flip flops, before forcing her to lay backwards across the comforter.  I reached under the mountain of belly sticking up into the air and unbuttoned the shorts, pulling them down slowly over her long silk and tanned legs before dropping them to the floor next to the bed.

Her tiny little polka dotted panties, clearly from her pre-pregnancy days, were barely visible.  The tank top had pulled up as she stretched her arms over her head, revealing the bottom of the belly and stopping just short of the painfully stretched belly button.  

“This baby must way 10 pounds” I teased as I straddled her.

“Fuck off!” she laughed back.

I licked the damp spots over her nipples on the tank top.  Her hand immediately caressed the back of my head, her slender little fingers running through my hair.  I felt the warm milk flood the material of the tank top as I took one of her perfect dark little nipples into my mouth.  They really were full and any sort of pressure caused them to drip her warm milk.

“Daddy” she whispered.  I could feel her back arching, causing her belly to push hard into me as I leaned over her still.

“Let me see you” I ordered, rolling off of her onto the bed.

Christina got up, slowly, and stood in front of me as I took down my shorts.  My dick was rock hard now and her eyes kept sneaking quick looks as she stood next to the bed.

“Take off the tank top”

“Yes, sir”

Once the shift was on the floor, I couldn't help just pause and stare for a moment as she stood there in front of me.  Her skinny little frame was barely supporting this massive belly.  I still dont quite understand the logistics to this day, but fuck it was beautiful.  Her perfect little tits, their dark little nipples, the tightly stretched skin, the poor belly button sticking out.  It was all just absolutely perfect, and I had to have it.

“Spin” I barked, stroking my big hard dick.  Her eyes watched intently with each pump.

She looked even bigger from the side as she spun.  The belly was just huge and so perfectly tight and round. Her tiny frame was meant to carry babies.  It was absolutely stunning to see at its absolute max.

“Is this ok?” she asked shyly.  

“Fuck yes.” I replied as she stopped facing away from her.  Her little polka dotted panties didnt even attempt to cover her ass cheeks anymore.  The hung out but at least two inches on each side, exposing almost half of her her tight little ass. 

Spinning to face me again, I could tell she was in pain.  Her hand rubbed the underside of the belly and I know I heard a faint little grumble under her breath.

“Contraction?” I asked.

“Yeah” she whimpered.  “Just give me a sec.”

“No” I said, jumping up from the bed and forcing her against the wall.  I took both hands and placed them flat against the wall above her head. She pulled one down and rubbed the contracting belly again.  I grabbed it, with more force this time, and placed it back on the wall above her.

“You’ll stand here and fucking take it” I whispered in her ear.  Watching her in discomfort was exhilarating and making her do as I said even more so.

“Yes, sir.” she grunted.

I smacked her little ass, hard.  Her cheek jiggled in the tiny little panties.  

“Good girl” 

I knelt behind her and buried my face in her ass cheeks.  My tongue ran across the line of the little panties and then traced the underside of each cheek, paying extra attention to the little valley where her ass met her leg.  I ran it up her crack, pulled the panties down just slightly and licked the top of the valley as well.

“Fuck” she whispered as the contraction subsided. I could feel her body loosen up a little as the pain faded.  

“You’re in labor, arent you?”

“I dont know.  I think maybe, sir”

“I dont give a fuck” I said, standing up behind her, smacking her little ass again. “You’re going to do what I fucking say you’re going to do.  Isnt that right?”

“Yes, sir” she replied as I turned her around again from the wall to face me.

“Get on all fours” I said, as I pointed to the bed.

Christina obeyed and I immediately stood behind her.  Her tincy little panties struggling even harder to contain her ass as she crouched there in front of me.

“Slow please, sir.” she said as I approached her from behind, grabbing her hips and pulling her toward me at the edge of the bed. “Its a lot for me to take in this position.”

I knelt behind her again and slowly traced the panty line over her cheeks.  Leaning up under her, I slowly licked the inside of each thigh.  I made my way closer and closer to her pussy, barely hidden by the polka dotted panties.  I could see the belly hanging down as I licked over the panties, teasing her swollen lips.

“Ugh” she whispered to herself.  Her little whispers made me crazy and that was all it took.

I jumped back to my feet and slapped her ass with my cock.  I then slid it between her legs until the tip bumped into the bottom of the hanging belly.  She reached for it and grabbed my girth with her delicate little hands, pulled aside the panties and slid me inside of her.

The first entry was long and slow.  I wanted her to feel every single inch of me as I slid inside of her tight little pussy.  She really was very petite and it was incredibly satisfying to feel her stretch and struggle a little as the last inch of me went in.  It was clear that she really wasn't designed to take a dick this big, which just made it all the hotter.  

The second pump was a little harder.  The third a little harder still.  My hands gripped her hips tightly as I continued to force myself inside of her again and again.  I watched as her hands squeezed the comforter tighter and tighter every time I slammed into her.  It was a struggle for her when she wasn't gigantically pregnant, so I can only imagine the focus it took to take all of me now.

“Daddy!” she gasped as her cheeks made that slapping sound against me that every man on earth absolutely fucking loves to hear.
“Yes, Daddy!  Yes!”

The slams continued.  Over and over.  Harder and harder.  I wanted her to scream for me.  I grabbed her hips and kept forcing myself into her, over and over.  Deeper and deeper. Her little gasps making me insane as we fucked.  

Suddenly, I felt her tighten around my shaft and begin to swell, tighter and tighter.  She was already getting close.  

“Yeah?” I growled.  “Is that what my girl wants?”

“Fuck, Daddy. Just like that.  Dont stop!”

I didnt.  I continued to pound her from behind, just like she wanted.  My big cock slamming deeper and deeper into her.  She continued to get tighter and tighter, swelling more and more with each slam.

“I’m cumming!” she whispered as she brought her hand up to instinctively squeeze her tits.  

Forgetting that she was due any second, she squeezed them hard as she came, milk dribbling down onto the blanket.  Her body twitched and she tightened around my shaft for one last earth-shattering orgasm before she had this baby.

I paused for a minute, my dick still deep inside of her, my hand still gripping her hips and holding her into me.  I could feel her twitch and throb.

“Fuck, Daddy! Fuck!” she said as I pulled out.  She quickly dropped to one side and rolled over onto her back to give her legs and arms some much needed relief.  

“You’re not done.” I whispered as I leaned over her.  I could hear how hard she was breathing, trying to collect herself.  

“Get on top of me.  Now.” I demanded.

“Yes, sir” she said as she struggled to get up from her back.  I layed on the bed next to her and helped push her to her feet.  She didnt hesitate for a second and was immediately on top of me.

“Good girl” 

I was inside of her again before I knew it.  Her long legs straddled me with ease and she wasted no time guiding my dick back inside of her.  I grabbed her fat little booty and forced myself deep inside.  

Moving my hands up her back, I forced her as far forward as the huge belly would allow.  My mouth quickly finding its way to her tits, I took her perfect little nipple inside, flicking it with my tongue..  Her sweet, warm milk flooded my mouth immediately.  I had never sucked a tit so full and ready for birth before and it was absolutely awesome.  Quickly, I moved to the other tit and sucked as well, swallowing mouth fulls of the warm liquid.  Her hands gripped my hair as I sucked.  

“God, they’re so full” she said as she pushed my head back into her tits for another round.  “That feels so good, Daddy.”

Her nipples continued to drip as I pushed her back upright to ride me.  I watched them drip even more as she bounced on top of me.

“Play with them” I instructed. 

She grabbed them and squeezed them while she rode.  Even more milk dribbled out and down across the top of her belly.  Faster she rode.

“I’m going to have this baby tonight.” she said as she leaned back further, resting her hands on my thighs.  She knew this was my favorite.  It forced the belly out and towards me.  I rested my hand on top of it as she continued to ride me.  

“Are you coming again?!” I asked, a little surprised.  Her head rolled back as she rode.  I could feel her swelling around my shaft again.  She was into it and I was loving it!

“”Put me into labor, Josh!” she almost yelled, her head still back, her back arched and her heavy belly bouncing as she rode me even harder. “I need this!” 

Before I even knew what was happening she exploded on me again.  Christina was a lot of things, but a twice in one night girl she was not.  I have no idea what made that night so different, but I didnt ask. 

Watching her bounce on top of me, her tits dripping, feeling her grip tighten as she came, it was more than I take.  I stopped holding back and released my load deep inside of her.  My hand was still on her stomach and I pushed hard into it, forcing her down hard onto me.  

When it was over, we both just laid there for a minute, sweaty and breathing hard.

“Thank you” Christina exhaled.  “I fucking needed this more than you know.” 

(Side note:  Less than 9 hours later, Christina gave birth to an 8 pound 7 ounce baby boy.)
