Chapter 4: Fruition

In the light of day, Andy was feeling humiliated and ashamed. Ejaculating all over himself in front of his hugely pregnant mother had been a somewhat traumatic experience. But could anyone really blame him? Her body had exploded into a baby-making sex machine, ripe and begging to be pleased... except for the fact that she was as cold as a Catholic nun during Lent.

There was only one solution. He had to remove himself from the situation before something terrible happened. He no longer trusted himself to be alone with her. Each day was agony, watching that glorious bursting belly, those firm thighs and ass, those perky milk-filled titty balloons. He just wanted to rub all over her, grabbing handfuls of flesh and exploring her body with abandon. But of course that was out of the question. There was no doubt he needed to move out of their small apartment as quickly as possible - for both of their sakes.

Andy began packing his things one afternoon while Rachel was out running an errand. It was borderline irresponsible for her to be out and about in her advanced state, but Andy was well past the point of being able to communicate with his mother, let alone persuade her to take some rest.

After he had packed up all of his most important possessions, he stood staring at the neat stack of moving boxes placed carefully near the front door. It was a little sad how his entire life could be contained in a few unremarkable boxes. Sighing, he grabbed a large box from the top and started toward his car, awkwardly fumbling with the door knob. 

Andy was startled when the door swung suddenly open. There his mom stood, breathing heavily and holding a grocery bag in one hand while her other hand rested on her large belly. It jutted out in front of her, straining against the dress that barely contained it. The stairs had obviously tired Rachel on the way up. Andy noted the rise and fall of her large, soft breasts as she gulped down air. But her brows were also knitted in discomfort. It must have been one of the Braxton-Hicks contractions that she had been experiencing more frequently. Looking up, she finally seemed to notice Andy. An awkward moment passed as they stared at each other. Seeing the stack of boxes, Rachel's face clouded with confusion. 

"Andy, what’s going on here?" she asked, looking to him for an explanation. 

Andy hesitated, then decided he might as well tell her the truth. He owed her that much at least. 

"I'm moving out. It's better this way. After what happened yesterday... it’s just for the best."

Rachel's emotions progressed rapidly from dismay to anger. "So you're just going to walk out and leave me alone like this?" she said, her voice rising in anger. She pointed at her huge belly, which looked ready to burst. "You put these babies inside me, Andy. I don't care what kind of sick fantasies you have, you need to step up and help me take care of them. It won't be long before…"

Rachel stopped suddenly, her eyes widening comically. Andy noticed a small stream of liquid trickling down her leg.

Chapter 5: Overripe

Rachel and Andy locked eyes, a brief moment that nevertheless seemed to contain fathoms: shock at the arrival of the long awaited (and feared) event, solidarity in the ties that inexplicably bound them together, and the impassible gulf between them caused by Andy's lust for his pregnant mother. The moment was short lived, however, as a wave of cramps seized Rachel's belly, causing her to moan with discomfort and clutch at her great mass. Seeing the pain written plainly on her face, Andy guided her to the sofa, where she sat heavily down. 

Leaning backwards against the cushions and with her tight dress now further stretched, Andy could clearly see just how taut and hard her belly had become. The twins had grown large and fat in her womb, totally indifferent to the fact that they were unwanted and unwelcome. It was like they had somehow fed off of Rachel's disgust and antipathy, growing as fast as they could to spite the poor woman. Looking at the incredibly fertile and fecund figure before him, Andy realized just how young his mother was. Her body was still in the prime of health and beauty, and pregnancy had only made her more attractive. Perhaps for the first time he saw her not as "mom," but as a beautiful young woman, not much older than he. 

Even in her pain she was beautiful. Her knitted brows and flushed face couldn't hide her full cheeks, dark sensual eyes, and wide pouting lips. Taking in her exquisite figure, Andy stood paralyzed. The heavy, overripe belly that dominated her torso perfectly complimented her wide, solid hips and her full, engorged breasts. She was the absolute image of femininity and sexuality, the answer to the question that men had asked ever since they started scribbling crude pictures on cave walls. 

Andy's reverie was broken when Rachel began to attempt to stand. "Help me to the hospital," she grunted, her eyes closed to the discomfort. Andy rushed into action and grabbed her arm, helping her to her feet. It seemed as if the contraction was abating. Rachel regained some control of her senses and began waddling heavily to the door, her belly thrust out before her. 

They had barely made it to the lobby when the next wave of contractions hit. This time they came on raging, causing Rachel to cry out in pain and collapse to her knees. "Ughhhhhhughgghggghhhhh!" she wailed, oblivious to the stares of a few other tenants checking their mail. 

"Uhhhhhh huhhhhhh! Mmmmmmm!" she cried. "Ahhhhh, I don't… think… I… can… MAKE IT! GOTTA… PUSH!" 

Rachel fell onto her side and then rolled onto her back. Andy was shocked to notice that she wasn't even wearing panties. He couldn't have known that she had long since abandoned these garments after it became too exhausting to pull them up and off every day. Her pussy lips peeked out from behind her sturdy thighs, pink, swollen, and glistening with her spilled waters. Andy could feel his member rising and engorging. The sight was too much for his body to resist. Trying to do something, anything, Andy removed his hoodie, wadded it, and placed it delicately under her head. Rachel seemed oblivious, only focusing on some inward reserve of strength and breathing deeply. 

"It's coming… help me!" she moaned and pulled her dress up over her great womb, which towered over her like a mountain peak. The grotesquely bloated belly shone with sweat as Rachel spread her creamy white thighs apart. Andy could just barely see her darkened areolas and nipples peeking out from below the folds of the rumpled dress. They looked so juicy and tempting, full of milk waiting to trickle out. He thought it would only take a stroke or two from his finger on one of those beautiful nipples to release the pressure. His hand itched at his side. Now he too was breaking out into sweat. 

But that was nothing compared to the glories of her now fully exposed cunt. The pink, plump lips were spread wide, revealing the luxuriously soft, darker pink flesh of Rachel's vagina. It was slick and glistening. Andy noticed her pronounced clitorous, neglected for so long. He desperately desired to place his mouth over it and tenderly caress it with his tongue. He could only imagine what it would feel like to bring her to orgasm, to feel her shudder and convulse as he licked and pleasured her. Andy thrilled at the thought that his big babies would also be sliding through those vaginal walls any minute, stretching Rachel's body to impossible degrees. He imagined one of those large heads, settling inevitably into position, traveling down and down, against her will, centimeter by centimeter, as her muscles cramped and forced the child along.

She would cry and protest, but her body would be in control, fulfilling its ultimate purpose. Modern society, Feminism, and gender equality wouldn't stand a chance against millions of years of evolution. It was Andy's job to plant his seed and Rachel's job to become the vessel. He loved how she had transformed over these few short months, becoming little more than a living womb. She was livestock, bred against her will and changed into a mindless birthing machine. He reveled in how absent minded she had become of late, brainlessly stroking her hugely pregnant belly and staring off into space. If only she could stay like that, Andy thought with regret. It was beautiful. She could grow, grow, and grow. Child after child. Accepting his seed, allowing him to fill her with his manhood endlessly. Surely that would be God's plan. Otherwise why had he created such a divine and tempting creature as his mother? 

Caught up in these thoughts, Andy ventured to feel Rachel's taut stomach. It was enormous, tight as a drum, and he could feel movement from within. Deep inside, his children were growing restless. He knew they longed to meet their father. Rachel hardly noticed, lost as she was in the pain. She was no longer in control, he thought with excitement. Her body has taken over. Andy's cock strained against the fly of his jeans. He was rock hard. This was the closest he had been to the object of his obsession and it was almost too much to take. 

Rachel's contractions had become incredibly strong and it was all she could do to keep up. She was now pushing with each one; there was no point in resisting anymore. She had to get these babies out. She was burning and her stomach felt like it was on fire. Feeling another strong contraction, she groaned and pushed. She immediately felt a new sensation. It was like she was being torn apart. The pain was incredible. She realized one of the babies' heads must be coming down her birth canal. It had been so long since she had given birth to Andy that she had forgotten what it felt like. Even so, this felt worse than she remembered. 

"Hhhrruuunngghhhhhhhhhh!!" Out came a gutteral grunt as she pushed again. The head was just too big. What kind of children had he put into her? 

"Aaahhhrrrgggh! I don't want it! GET THEM OUT OF ME!" she screamed. 

Andy looked down between her legs, deep into her vagina. He couldn't even see a trace of the babies' head. There was still time. It would be a little while before she would be able to push one out. He imagined sliding his cock into that velvety opening and fucking her in the final moments. He would run his hands all over her glistening belly, feeling her body squirm. She would protest, but she would be completely helpless to put up a fight. 

He shuddered and involuntarily released a huge sticky load into his boxers. His cock pulses, sending cum trickling down his thigh and dampening his pants. In his mind he was coating the walls of her cunt with large ropey blasts of semen, that sacred space his unnatural offspring would soon pass through. 

Rachel's pushed again, screaming. "It's too big! I can't do it!"

Andy took in a ragged breath, feeling the endorphins rush through his brain. Now calmed a bit, he tried to reason with his mother. 

"You've got to push it out, Mom. We don't have time to get to the hospital. You can do this. You were made for it."

Rachel felt another contraction right on the heels of the last one. 

"AAAHHHHHH! FUCK YOU! YOU FUCKING DID THIS TO ME YOU LITTLE PERVERT! HHHHUUUUUNNNNNNGGGGGGGGHHHH"

Still looking down between her legs, Andy caught a brief glimpse of the head before it slid back into her body. He wasn't a doctor, but that head looked way too big to fit through her small opening. It would be interesting to see how she would push it out. 

"Keep going. I saw the head for a second. Your body is amazing, mom!" 

Rachel couldn't respond to her son's strange comment. It was all she could do to keep pace with the contractions. She pushed again, a gut wrenching exertion, and this time she felt the baby moving through her. It's huge head was now stretching her pussy lips taut in an exaggerated O shape. The pain was immense. 

"IT'S STUCK, IT'S STUCK! OH MY GOD IT HURTS. WHAT DID YOU PUT INTO ME???" 

"That's one big baby, mom! I can't believe you grew that! No wonder your belly got so big!" 

Part of Rachel's mind knew that Andy was getting some kind of sick pleasure from this, but it wasn't something she could deal with at the moment.

Feeling pressure building, she made another big push. She was certain the huge incestuous baby was going to rip her vagina. It felt like a ring of fire. After an eternity of suffering and pushing, she felt the baby's head break through. Mercifully, the rest of the baby slid smoothly out of her body. 

Andy wrapped the baby up in his flannel shirt, the umbilical cord still connected inside of Rachel's body. It was awkward holding the child. It made a cry, small but strong. Yes, Andy thought, they made good babies together. He didn't have long to ruminate on the miracle of life, however. Rachel had already begun to push the other baby out. 

Despite the pain, she was obviously set on vacating the second inhabitant from her body. Screaming, she bore down and forced the baby towards her entrance. But like the first time, the baby was having difficulty making progress. Taking a moment to gather her strength, she made another great push. 

"AAAAAARRRGHHH! WHY… WON'T…. YOU… GO!!!" she screamed in frustration and exhaustion. 

"That must be the bigger twin!" Andy said, laughing. "I read that there generally is one that's larger than the other."

That bastard is enjoying this, she thought. WHAT THE FUCK, ANDY?? WHAT THE FUCK IS WRONG WITH YOU?? 

But she was caught between a rock and a hard place now. The disgusting thing couldn't stay in her, she knew that much. She just had to pray that her body could somehow handle the monstrous child. 

"HUUUUUNGGGGGHHHH! OH JESUS!!!" she screamed as she put her whole soul into ridding herself of the shameful burden she had been forced to carry for these nine long months. It had been the worst experience of her life. Not only had she been shunned at church, but her body had completely transformed, turning her into a huge pregnant cow. She had hated that heavy, terrible belly, how it had grown and grown, pushing her clothes out further and further. She hated how her belly button poked out like another nipple. She hated how her center of balance has completely shifted, making every step awkward and obvious that she was filled with child. She loathed the movements of the growing babies and how they reminded her of their horrible source. She hated the extra attention she received from men, which had only increased as she had grown absudly big. And most of all she hated how her body had embraced this intolerable transformation, pumping her full of life until she was more pregnant than any woman she had ever met. She just wanted her regular body back. 

Her epic struggle ended abruptly when the second baby popped out of her vagina. It was a monster of a thing. There's no way that thing isn't 10 fucking pounds, she thought in a daze. She was seeing stars and sucked in oxygen greedily. After what could have been seconds or minutes, she felt a warm bundle against her breast. Opening her eyes in confusion, she saw Andy attempting to place the big baby in her arms.  It's twin was lying on the ground next to her, still wrapped in Andy's shirt. In the distance she could hear the sound of an approaching ambulance. 

Rachel glared at Andy, pure venom in her eyes. She pushed the baby back into his hands, catching him off guard. 

"Wha…?" he began to protest. 

Rachel cut him off, all of the rage she could muster in her voice. 

"Here's your son… son."

Then the red and blue ambulance lights filled her vision and she drifted off weightlessly into darkness. 

Epilogue 

Rachel woke up groggily. She had drunk too much the night before and she knew it. The last year and a half had been hell. After putting the twins up for adoption (she couldn't stand even the sight of them), she had placed a restraining order on her son. He had completely lost his mind, it seemed. Her heart broke every time she thought about it, but his obsession with her pregnancy had put them both in danger. She knew that now. Still, she had not expected how crazed he had become during the court appearance. He was demented, it seemed. 

So she had crawled into a bottle and stayed there, unwilling to face reality. Only recently had she tried to pull herself together and get back to church. Last night had been a regression, but even so she felt even more out of it than usual. 

She swung her legs out of bed and stared woodenly into space. An unusual sensation brought her back to reality. She felt something ooze lazily out of her, plopping onto the bedsheet, and then a small puff of cool air rush in to fill the vacuum. Confused, she looked down between her legs. A thick, white goo covered the sheets. Touching it with her fingers, it took only a moment for her to reach the terrible conclusion. Neurons fired across superhighways of fear, shock, and horror. 

Jumping to her feet, Rachel shouted in a hoarse, crazed voice, "ANDY!!!"

Nice, mesarocket. Baby #3 maybe on the way for Rachel? Andy envisioning Mom turned into constantly bred baby making machine.

Awesome birth scene!! Great job!

Definitely a bittersweet ending.

I personally like father/daughter over mother/son, but you are an excellent author and I've enjoyed everything you've written.

I thought the birth was great as well! Like @pokemun I prefer f/d incest.
