"You got it," Todd leered.
His ass jerked with lightning speed as he hammered his meat into her. She screwed her eyes shut and blotted out everything else, carried away by the hot pleasure he was giving her. Her face was contorted into a lusty grimace, and she clawed the bed. Matt could almost feel her gripping juicing cunt as she flew to the brink of climax.
"Unnnggghhh, baby, I'm coming, unnnggghhh!" she groaned.
"Take my load, Sis, aaaggghhh!" Todd bellowed.
Matt took advantage of all the noise they were making and groaned with frustration. He figured he might as well jack off against the door and get it over with, but then his resentment took over. Why should he have to stand out in the hall beating off like a guilty little kid? Why couldn't he fuck Terry, too? He stood there holding his drooling engorged prick and seething.
That was the position his mother found him in when she came upstairs looking for the kids. Irene had returned from her brief shopping trip and found Terry missing and the housework not finished. Annoyed, she tiptoed upstairs, expecting to find the kids goofing off. At the top of the stairs she glanced around and almost fainted. She certainly wasn't prepared for what she saw.
There was her youngest child, Matt, kneeling at Todd's bedroom door and playing with himself. He was peering through the keyhole, red-faced and panting. His jeans were tugged down, and he had his cock in his fist, pumping it. Irene was so shocked she couldn't move to scald him, couldn't even make a sound.
As she watched, Matt stopped pumping his cock and just crouched there holding it. Irene wondered what to do. It was terribly wrong of him to masturbate, of course, but the situation was so embarrasing. How could she talk to him with his naked cock hanging out? The mortified housewife just stood there and slowly turned red all over.
Then Matt got a determined look on his face, stood up, and walked into Todd's room, slamming the door behind him. Irene just had to know what was going on in there. She went quickly and quietly to the door, knelt, and looked through the keyhole. Once more her mouth dropped open and she went red with shock.
On the bed were her other two kids, Todd and Terry, and it was obvious that they'd just finished fucking. Todd was in the act of raising himself off his sister, and his cream-soaked cock was emerging from her cunt. They were both staring at Matt, who was stripping naked.
"Hey, little brother," Todd snapped, "what do you mean by busting in here without knocking?"
"I just want a turn with Sis," Matt said determinedly. "How come I have to be left out of the fun?"
"Well, who said she wanted you?" Todd replied.
"Hey, you two, take it easy," Terry said soothingly. "I like to fuck both of you, so there's no problem. Come on over, Matt, we've got time for a quickie."
"Terrific," he grinned.
He hurried over to the bed, his teenage cock so stiff and swollen that it hardly quivered with his movements. Todd looked a little pissed off, but also excited by the idea of watching his brother and sister get it on. He moved to the far side of the bed and got comfortable.
Matt slid onto the bed, and Terry grabbed greedily for his cock and started pumping it. "Mmmmmm, what a gorgeous hard-on," she purred.
Matt grinned, cupped her tits, and started playing with the hot little globes, white Todd began to grin, really getting off on the scene. The incestuous trio seemed completely uninhibited and at ease. Irene watched openmouthed, hardly believing her own eyes. She and Glen had raised the children so strictly and carefully. How could they possibly be doing something like this?
"I like to fuck both of you," Terry had said. That meant this wasn't the first time they'd done it. How long had it been going on? And what possessed the kids to do such a wicked and outrageous thing? Irene knew she ought to march in there and read them the riot act, yet she couldn't move. She felt a weird kind of fascination as she watched.
Matt had slipped his hand between Terry's thighs and was massaging her pussy. She gurgled with delight and pumped his cock. Neither one of them showed a trace of guilt as they, played with each other, and Todd didn't look guilty, either, as he grinned and watched. In fact his cock was getting stiff.
Irene felt just a touch of envy. She wished her and Glen's love-making could be so lighthearted and guiltless. But that wasn't the way they'd been brought up. They'd both had moralistic strict parents who preached to them that sex was the work of the Devil. So when she and Glen made love, they acted like they were committing a crime.
They always did it in the dark, under the covers, and they always used the same position, Glen on top. They didn't allow themselves any foreplay. It was just a quick fuck, long enough to get both of them off, and that was it. Irene secretly enjoyed even that meager ration of sex, but as she watched her kids she realized what she'd been missing. There was a whole world of pleasure that she and Glen hadn't explored.
"Here's something we haven't done yet, you guys," Terry chirped. "It's called sixty-nine. Lie on your back, Matt."
Irene found herself watching in lusty fascination as Terry crouched over her brother backs, her mouth poised right over his stiffstanding cock, her steamy pink slit almost in his face. She stuck out her tongue and began to lick up the cream that bubbled from his piss hole, and Matt gave a happy groan.
"Hey, what a terrific idea," he said.
"It sure is," Todd agreed.
Glen and Irene, of course, had never tried oral sex. It sounded like too much fun, and fun was out. Now she found herself creaming right through her panties as she watched Matt and Terry eat each other. While his sister licked his cock, Matt flicked his tongue stiffly up and down the juicy line of her slit, and she squealed with pleasure.
"Oooooo, yeah, honey, I love that," she cried, "keep doing it to me, don't stop."
Irene had a wild impulse to be in Terry's place, tasting cock cream and getting her pussy licked. It was awful of her to think such things, but she was helplessly excited. Her sex life was so limited, so boring. She and Glen had fucked the same way for twenty years, and they hadn't tried anything new since their wedding night. It would be such fun to experiment.
She shivered lustily as Terry brought her lips down around the fat head of her brother's cock and started sucking on it. Matt groaned blissfully, then returned the favor. He made his tongue long and stiff, then crammed it into his sister's cunt and started jerking it in cock-like motions. Terry gave a muffled moan of ecstasy.
Irene moaned, too, then reminded herself to keep quiet. She didn't want to be caught like this, spying on her kids and creaming through her panties. Still she couldn't ignore the blazing need in her pussy. She wondered what it would be like to suck a cock, to take a man's stiff tongue in her cunt.
Pretty soon Terry raised her head and said reluctantly, "I guess if we're gonna fuck, we better do it now, Matt. Mom's gonna be home any minute now."
"Yeah, right," Matt said.
Terry crouched in the doggy position, and Matt knelt behind her and slid his steel-hard cock up her cunt. She gurgled with pleasure and clawed the bed. He began to fuck her in quick urgent jabs. Then Todd crawled over and knelt in front of her, trailing the drooling head of his cock over her lips.
"How about getting me off, too, Sis?" he leered.
"Two cocks at the same time?" Terry grinned. "Fantastic."
She opened her lips wide and let him slide his engorged boner into her mouth. Drawing in her cheeks, she began to suck on his meat, and he groaned with excitement. Terry as wildly aroused as she took swollen cocks in her mouth and cunt. Hot cream poured from her twat and gushed down her legs.
"Mmmmm, uuummmmm," she moaned.
Irene caught herself panting as she watched. She felt so envious! Terry and her brothers had so much more experience, so much more fun, than she and Glen had ever had. She wished there was some way she could experience some of the kinky things they did, but she saw no hope of that. Glen would be furious if she even mentioned it.
