Parker

Parker heard his sister walk off towards their brother Jason's room as he walked down the stairs. He descended slowly, taking care to avoid the steps that creaked. He peaked into the kitchen, seeing his mother still puttering about. He took a moment to really appreciate her body, her motherly hips being her best feature, curving out from her waist to form perfect hand holds. Parker felt his cock drooling at the thought and didn't bother to wait any longer. The next time his mother turned her back to the door, he rushed her.

Arielle heard something behind her and turned, thinking it was one of her children. She had barely turned around when a solid mass tackled her, sending them both to the ground. The person landed on top of her and held her arms down on either side of her head, something poked her in the thigh.

"Parker?!" she exclaimed in surprise at the sight of her more muscular son hovering over her. "Wh-what happened to you?"

"I don't know, but I don't care. I feel great, I'm sexy as hell, my dick is hard, and I want to fuck! So I'm gonna fuck you," he said, tearing at the older woman's pants. He quickly tore them apart, baring his mother's cunt. "I'm gonna fuck you, fill you with my seed, and make you pregnant. I'm going to fuck your own grandchild into you."

"No, stop this! I don't know what happened to you, but we can figure it out! Just calm down and we can talk this over." Arielle said as she struggled beneath her son's weight. Parker smiled menacingly.

"Sorry Mom, you know what they say: actions speak louder than words." He slowly pushed into his mother's vagina, making her squirm at the intrusion. Parker groaned as he slipped inside. "Oh, yeah, that's good. I can see why Dad still wants to fuck you all the time. Not as tight as Rachel, but pussy is pussy." He started to thrust into Arielle, pushing deeper and deeper with every stroke.

"W-what are you sayi-saying?" Arielle gasped out as her son pounded her, sending her sizable boobs quivering, blonde hair pooled around her head. Her son slowed his fucking for a moment.

"I'm saying I already fucked Rachel over the counter upstairs. She wasn't into it at first, but she came around until she was begging for my cock. I filled her up just like I'm going to fill you up." They heard a yell echo through the house, coming from upstairs. "Sounds like she found Jason after all. I bet he's getting the ride of his life. Rachel is a lot sexier now after all. Those little boobs of hers are fat knockers now. I can't wait to see them bounce when I fuck her again later." Parker picked up his pace again, forcing his fuckstick deeper into his mother.

"No, Parker, PLEASE! This is wrong, you have to stop," Arielle said, her voice a higher pitch than usual. "There's something wrong with you, you need help. Please!! We ca-" she choked on her next words as Parker slammed into her hard.

"I'm perfectly fine, slut," he said with a dark tone. "The only thing wrong with me is that I can't see your tits bouncing." He tore his mother's shirt off, exposing her breasts heaving in her bra. He snapped the garment off, the woman's boobs shaking as they drooped on her body. "Those are pathetic, barely tits anymore. But don't worry. Rachel got plenty big tits when I came in her, I'm sure yours will be even better, since you've got a head start. Plus, you'll need plenty of milk for our child." Arielle moaned in despair at his words, knowing she was completely helpless to stop him anymore. Worse, her son's cock, bigger than her husband's, was starting to feel good. She was ashamed that she couldn't stop herself from twisting her hips slightly, ensuring he hit a better spot inside her.

"Oh yeah, mom, get into it. It's so much better that way. Enjoy your own son fucking you deep. I'm gonna cum soon, so get those eggs ready. I'm going to fill you with so much baby batter there's no way you won't be pregnant." Parker said, grabbing his mother's rolling tits, squeezing them in time to his thrusts.

Arielle moaned more, giving in to the pleasure that was echoing in her brain. She could remember being pregnant with the twins and then with Jason, remembered loving the feeling of growing bigger and bigger with her children. Her tits had been so much more sensitive and got bigger too. And now, about to be bred by her own child, she couldn't help but look forward to those things again. She bucked into her son's thrusts, moaning like a whore as his cock swelled.

"Yeah bitch, that's right, fuck me back. Fuck your son as he drills your dirty cunt. As he breeds you. I'm going to fill you up!" Parker roared as his orgasm hit. "Take my seed and make my child, you breeding WHORE!!" He yelled loudly as he felt his cum spill out into his mother, the hot liquid filling her as he emptied his balls.

"OH FUCK YES! MAKE ME YOUR PREGNANT BITCH, PARKER!! FILL ME WITH YOUR CUM!!" Arielle screamed as she felt her son's cum shoot into her, unable to handle the pleasure of being bred. She orgasmed violently, arching her back off the floor and clenching her pussy tight around her son's spewing cock, ensuring no drop of his seed escaped her. She felt the heat of his cum spread through her body, firming flesh and stripping years away. Her flab disappeared and her breasts regained their youthful firmness before going beyond it, sitting larger and higher on her chest than they ever had before. She felt an ache within them, something she was well acquainted with. She tweaked her nipples and fresh milk flowed out, ready to nurture her children. But most of all was the swelling in her womb, stretching her abdomen out as her new pregnancy accelerated. In a mere two minutes, she went from looking like a woman past her prime to an image of fertility seven months pregnant, practically begging to be filled with new children.

Parker shot one last stream of cum into his mother before he pulled out, more than pleased with his work. He ran a hand over his mother's taunt stomach, feeling the life of his child inside her. He knew it would be perfect and built for sex, a lusty creature just like its mother and father. Arielle continued to moan on the floor, her mind reeling from the rapid changes to her body. She felt a tender affection for the child in her womb and a ravenous lust for its father's cock. Or any cock really, so long as it was in her pumping her full of more life-making seed.

"Come on then, you pregnant whore. It's time you met your changed daughter, and probably your other son. I'm sure they've been busy."
