"Yes, Kenny!" Diane winced as she felt his big prick head pushing inside her, stretching her tightly muscled asshole around the invading thickness of his cock. "Oh Christ, so fucking good! Don't worry about hurting me, darling! Your cock's nice and wet from my cunt! Just fuck me! Fuck the shit out of my Goddamn ass!"
Kenny shifted on top of her, changing his position so that his swollen prick would fuck directly into the forbidden tunnel of her ass. Then he groaned as he started humping, bucking harder than when he'd fucked her cunt, fucking inch after inch of his aching cock into the rubbery grip of his mother's asshole.
"Yes, Kenny, oh yessss!" Diane wiggled and humped excitedly beneath him, gasping with pleasure as her tight asshole stretched to admit his cock. There was no pain as he stuffed his cock into her ass. Instead there was only pleasure… hot, burning pleasure as her asshole muscles milked his throbbing prick.
"It's so tight, Mom," Kenny groaned. "I don't know if I can get it all the way in!"
"Yes you can!" Clawing the sheets, Diane humped her ass like a bitch in heat. "Fuck me, Kenny! Fuck that whopper all the way up my ass!"
Kenny gritted his teeth and pushed down harder. Finally his balls rested against her ass cheeks, and every inch of his hard-on was in the exquisite tightness of his mother's shitter.
Kenny pulled out of her throbbing tunnel, making Diane squeal as his cock meat dragged up her asshole walls. When only the knob parted her ass lips, he bored his prick back home. Then he started to fuck her asshole with a slow, brutal rhythm, fucking his spongy cock head deeper into her ass with every stroke.
"Fuck me faster, Kenny!" Eagerly Diane worked and wiggled her rounded ass cheeks, continually flexing her asshole muscles to suck and milk the steely shaft of her boy's prick. "Your cock is so long and fat! It feels so good in my asshole! Gonna cum again, Kenny! Aw Christ, fuck the shit out of my ass!"
Kenny fucked his mother's asshole harder and harder, fucking his cock wildly between her cheeks with every stroke. Diane's asshole began to burn and pulse. Hornily she thrust her hand under her belly, groping through her pussy curls. She buried two fingers in her gurgling cunt and started to jack off as her asshole was fucked.
"Fuck me faster, Kenny!" she pleaded. "Faster, faster, fuck my ass as hard as you can! Ungghhh! Oh fuck, it's so gooooood! Awwnnngghh! Gonna cream, Kenny! I'm cumming, I'm cuuuunimmiiiinnnngggggg!"
Her asshole exploded, pulsing violently around Kenny's cock as the spasms gushed through her naked body. Again, and again Diane's asshole convulsed, contracting around the aching hardness of her boy's thick prick meat.
Kenny fucked his prick furiously into the depths of her shifter. Diane's pussy gushed cunt oil as the cum overwhelmed her body. Then she felt Kenny's hard-on growing longer deep inside her, and knew he was cumming too.
"Making it, Mom!" Kenny cried. "Ahhhhhhh…"
He came, shooting streams of hot, milky jism into the rubbery depths of his mother's asshole. Diane whimpered as he came, feeling her burning ass walls anointed by the liquid spray of cum. She flexed her shitter muscles, helping her darling Kenny squirt every drop of jism into her hungry ass.
And she didn't feel guilty at all.
CHAPTER EIGHT
It was just after two, and as she stood in the kitchen Diane could barely restrain herself from watching the second hand make its trip around the clock. Her son would be home any minute. She couldn't wait to feel his big cock fucking deep inside her.
Two days had passed, and Diane felt more sexually satisfied than at any time in her life. Kenny and she were fucking constantly, even with two other children and a husband in the house. Somehow they always found a place where Diane was sure no one would catch them.
There was no more shame. She'd given in completely and happily to her need to suck and fuck her son's magnificent prick.
Now she wore a light summer dress with a deep cleavage and a hem that barely covered her ass cheeks. Under the dress Diane wore no underwear. Her huge tits jiggled as she moved, and the stiff nipples protruded through the dark-blue fabric. Diane hoped that Kenny would be turned on by her luscious, bare thighs, and if that didn't work, she could always bend over to let him see her ass cheeks and hairy cunt. She wanted Kenny to be so horny that he would fuck his cock up her pussy as soon as he came home.
Any moment, Diane thought, watching the clock.
Kenny was already in the habit of skipping his last class so he could give his horny mother a good fucking before Mike or Penny got home. Diane smiled as she remembered how she had once insisted on a perfect attendance record. Now she would have begged Kenny to skip his last class if he hadn't thought of it first.
The front door opened and slammed shut. Diane's heart skipped a beat, and her pussy juice warmly as she heard footsteps in the hall, moving toward the kitchen. But when she turned, she didn't see the face of her second born.
Instead it was her first child, the tall, muscular, wickedly grinning Mike.
"Mi-Mi-Michael," Diane stammered. "What are you doing here so early?"
Mike wore a pair of jeans and a tight t-shirt that showed off his muscular physique. He leaned against the refrigerator, effectively blocking his mother's exit, and lifted his hand to pick his teeth.
Even before he spoke, Diane felt her lust replaced by fear. There was something in Mike's expression that told her that he was up to no good, and that the no good would be done to her.
"Oh, I just thought I'd skip my last class," Mike said breezily. "It being such a nice day and all. You don't mind, do you, Mom?"
"Well… yes, I think I do mind, Mike," Diane said defensively. "Once in awhile is all right, but your grades haven't been the best lately. I think that as long as you live in this house you should…"
"But, Mom, you don't mind if Kenny comes home from school early, do you?"
There was a long pause. Diane felt an embarrassed flush spread through her cheeks as Mike smiled at her lightly. His gaze lowered, and for the first time she became conscious of how unusual it was for her to be doing her housework without a bra on.
"Kenny… Kenny has been helping me with a little housework," Diane lied stiffly.
"He was just trying to be considerate, unlike some children I could name."
"Aw, bullshit, Mom! You are such a fucking liar!"
His rage was sudden and frightening. Diane felt herself cowering against the counter as Mike walked menacingly toward her, his expression frozen with rage. When he stopped, he was so close that their bodies almost touched.
"The only housework Kenny's helping you with around here is with your pussy! Don't try to lie to me, Mom! He's been fucking the shit out of you!"
"Mike, how… how dare you say such things to me," Diane stammered weakly. "You leave me alone. You were always such a horrible…"
"I know because I heard you, Mom! The two of you were humping so loud yesterday afternoon that I guess you didn't even hear me open the Goddamn door."
Mike stepped still closer. "And if you're wondering where he is now, you might as well forget about it until dinnertime. He's not coming anywhere near here till then. I told him if he did I'd beat the shit out of him. And you know fucking well that Kenny's so scared of me that he'll do anything I say!"
"Everybody's scared of you!" Diane retorted tearfully. "You're so mean that nobody can like you! The things you're saying to me now! I can hardly believe you're my son."
Mike seemed to hesitate for a moment, but then his smile became even thinner and crueler. "You never did give a shit about me, Mom. You always waited on Kenny hand and foot, and now you even started fucking him. Well, I think I'm going to take some of that for myself too."
Then he was all over her, pressing his body to hers and wrapping his arms tightly around her. Diane struggled to escape, but it soon became obvious that Mike was much stronger than her. Insistently he covered her with kisses, biting her neck and hungrily squeezing her ass cheeks through the dress.
