"Come on," Bettina hissed. "Fuck him. You know you want to."

"No – no – no!" Lauralee insisted, struggling to free herself.

Then she felt Robbie against her from behind, felt the warm touch of his body, the very hard length of her son's prick nestling into the cleft of her buttocks. She tried to roll away, to wiggle from beneath his weight. But he slid off only to take a from grip upon her ankles, and she knew terror as he pulled her legs apart.

"Don't – oh, don't do this," she begged. "Robbie – Bettina – think what you're doing! Oh please, please…"

The girl's face was intent, the green eyes fixed upon her. "Don't fight it, Lauralee. If you'll admit it, you want to be fucked by him as much as he want to put his meat to you."

"NO!" Lauralee fought as best she could, her long legs flailing, jerking at her trapped wrists and hissing between clenched teeth. "B-bettina! He's your husband, and my-my own son! You can't HELP him do this – Robbie, Robbie! It's rape-rape; you're trying to rape your mother, Robbie!"

"Yeah," he grunted from behind her. "I'll take that sweet pussy any way I have to get it. Just relax, Mom. Bettina – help me roll her over onto her back."

They wheeled her, whipped her over, and Lauralee was staring up into her son's face as he smiled down at her, as his knee slid between her thighs and forced them apart, as one hand pressed down upon her heaving belly. Robbie held his prick tightly in the other hand, and was steering the distended bulb toward her crotch. She could see a droplet of clear fluid shining upon the blunt red tip, and shuddered.

Her hands were drawn above her head, and even though she rolled her hips frantically, Lauralee realized that she wasn't going to be able to stop it, that her son was about to force his bulging cockhead into his mother's quivering vulva.

When it touched her pubic hair, she lunged and bucked, but that only helped Robbie settle the head of his eager shaft into her cunt lips. With a single, fierce thrust, the boy crammed his meat into her, and Lauralee knew a hot, electric shock as her son's knob penetrated her vagina.
