"You little shit!"
Denny froze with his shorts around his ankles, his dick in hand. He'd been enjoying peeping in on his 20-year-old sister Cora, as she rode her boyfriend Mike's dick. Her body was fucking amazing, an angelic face on a body built for sin. Those tits were at least a 36D, those hips made his dick twitch, and the way she fucked like a rabbit in spring, made his 18-year-old prick steel hard, and he'd been peeping for the last few months.
He had just watched her riding Mike's cock, shaking and shuddering, the sounds of orgasmic pleasure joining in. She'd been in a reverse cowgirl, his dick had been rock hard as he watched his sister's big milk jugs jouncing around, her hips, nice and wide, spread apart over his hips, the neat little landing strip of red pubic curls going up and down, and when she opened her eyes, she had looked right at the small space where her door was ajar.
''You pervert, get your ass in here, NOW!"
Denny meekly did so, his eyes wide as he stared at his sister, still naked and perched on Kevin's cock.
"Look down at the floor you little shit! You've already seen too much of me, creepy little perv! I thought you'd been spying, you know what Mom would say and do when she gets home and I tell her what a little snooper you are!"
Denny did indeed, their mother was a firm believer in 'spare the rod, spoil the child,' and she was not at all slow in enforcing that.
"Now, what shall we do with you?"
He could see the hint of a smile start playing around her lips, and in spite of the situation, his 7 inches stayed rock hard, refusing to deflate. She was looking right at his dick, and her smile got wider.
"Okay, Denny, time for you to pay the price!"
She got up, and the sight of her nude body coming closer made him tremble. She gripped his hand, and pulled him to the bedside, Denny meekly trailing in her wake.
"On the bed!"
He did so, wondering what was going to happen, he was not expecting any of this. Cora's next order made him tremble.
"You are going to fluff up Mike's cock, I want to see you suck his cock!"
At his wide-eyed stare, she said, "Do you prefer the alternative?"
The alternative was telling Mom what a spying pervert he was. Once she got home and heard from Cora, he'd be hauled off to the basement. He'd be stripped, his wrists cuffed to a post above his head, and Mom would take her riding crop, and really whack his bare ass, WHACK...WHACK...WHACK...WHACK... She would blister his ass with 10 very hard strokes, and his ass would be a stinging, throbbing nest of red stripes, testament to her style of discipline. He'd had that once, for mouthing off, and Mom had heard it, and he'd gotten it. Once was more than enough.
He saw Mike's cock, it was half-hard, and he steeled himself for the task at hand. He crouched over Mike, lowering his mouth until his lips touched his cock, he felt it jerk like it was beckoning him on. He closed his eyes, and pushed his mouth down, letting his mouth slide around his dick, feeling every ridge and vein of the cock in his mouth, Mike grunted as he did his best to take in as much as possible.
Knowing what to do from the blowjobs his girlfriend had given him, he made his lips a little tighter and started to slowly ride his cock. He could taste Cora's juices smeared all up and down the shaft. The knowledge that he was tasting the essence of her pussy started a dark bolt of forbidden lust ride up.
Mike felt him get better, oh yeah, his lips tightened around his shaft, the sizzling pleasure as those tight lips slid down his shaft, his cock in a hot, wet vortex of sucking as he swallowed 6 of his 8 inches. Denny got into a rhythm, riding his pole with lust-driven heat.
Cora was getting very hot, watching little brother suck Mike's cock was damn exciting, she cooed, "How is my little bro at sucking cock?"
