Debby made little moaning sounds as Kevin continued to force his cock into her silky crotch. Through the fog of sleep the girl felt something hard and hot poking her between the legs and instinctively opened them, lifting and bending her knee at the same time. Kevin moved toward her the same time and felt the tip of his cock pop between his sister's tight, elastic little cuntlips. Debby's eyes flicked open, but before she could say or do anything, Kevin hunched his hips forward and buried his massive boner to the hilt in his sister's hot little cunt. Debby moaned low in her throat, grinding her cunt against the long, thick incestuous invader.
God, it felt so good. She always felt horny in the mornings, and at home she often brought herself off with her fingers a couple of times before breakfast. Now, she had a big, hard cock… her brother's cock… and it was much more satisfying than her fingers. She didn't mind fucking him, now that her father had shown her how much fun it was. Hell, she'd even let that punk, Bobby, fuck her if he wanted. Her mother had sure squealed for more when he stuffed that big fat prick of his into her cunt. Her mind reeled with the possibilities, but right now all she cared about was getting more of her big brother's prick into her horny pussy. The ropes that bound them were a bit of a hindrance, but where there's a prick there's a way, Debby thought.
She opened her thighs as far apart as the ropes would allow and began to hunch her ass in time with her brother's eager cock-thrusts, but it still wasn't satisfying. She longed for the deep hard thrusts her father had given her the night before, but Kevin's bonds kept him from moving his hips much. His cock was fully into her cunt, but movement was severely restricted. Debby began to rock her hips and moan in frustration as her brother's cock filled and tantalized her young horny pussy. Kevin too, was beginning to feel the strain, it was agonizing to feel his cock finally inside his sister's tight, wet little cunt and not be able to pound away at her the way he wanted to. He was just about to try and wriggle out of the ropes when he felt the cold steel of a gun barrel against his neck.
"Well, well, well! What have we here?" grinned Bobby, running the gun barrel down over Debby's tightly clenched ass. "A little friendly brother and sister good-morning fuck?"
Kevin and Debby froze as Bobby ran the gun barrel over their naked bodies. He kicked Dick and Lisa who were still asleep at his feet. Dick awoke with a start and gave his wife a gentle pat on the ass to wake her.
"Hey, Red!" Bobby snickered, pointing at Lisa's tied son and daughter. "Looks like your kids wanna play a little house too. And, if I'm not mistaken, hero here has his wiener well and truly stuffed up sweetcheek's hot little fur-pie."
Lisa glared at him, casting only a fleeting sideways glance at her two bound children.
"What do you expect, after the things you made us do last night and the way you tied them up together!" spat Lisa.
"Whoa, baby! Excuse me?? I didn't make you do anything! You and the rest of your hot fuckin' family were only too happy to get it on together, baby! So, don't come with this 'I made you do it' crap, 'cause you the old man here were having a hot old time with the kids last night without me forcing you to do anything!"
Lisa scowled at him, realizing shamefully that he was right. She definitely did enjoy her son's hard young cock stuffing her ass and pussy, and her husband sure as hell got a kick out of fucking their daughter, that was for sure…! What could she say?
Bobby saw the woman's downcast expression and smiled, knowing he'd won again. Now it was time for the next episode in this horny family's sexual awakening. He stood up and untied the two kids, letting them sit up. Kevin's cock slithered reluctantly from the tight confines of his sister's hot young cunt, leaving a trail of glistening pussy-juice along the girl's thigh. Debby sat with her arms folded across her teenage tits, her legs tightly clamped together.
Despite having fucked her father the night before, in the cold light of day, the young girl felt ashamed at being caught with her brother's cock up her cunt, especially in front of her parents. Bobby sat down on the sofa beside Debby, admiring her gorgeous young body. He couldn't blame Kevin for what he did. ANY brother would want to fuck a sister like that, he thought. Then, suddenly, he had an idea! He ran the gun up and down between Debby's firm young tits and grinned at her lewdly.
"Maybe sweetcheeks would prefer a real cock," he said, stroking his stiffening prick meaningfully with his other hand.
Debby could only stare speechlessly at Bobby's lengthening cock. Kevin's hard prick had felt so good up her cunt that the horny youngster was willing to do anything to finish off what her brother had started. Lisa tried to rise, fighting against the ropes that held her tied tightly to her husband. Dick held her to him, knowing that to fight against it was useless. Bobby held all the trump cards. He'd unleashed their sexuality and now, only consummation of that sexuality would leave him powerless.
It was Kevin who finally stood up and bravely confronted the gun-wielding fugitive. His cock had tasted the tight, juicy delights of his little sister's hot clinging cunt, and the boy wanted more. He was willing to do anything!
"No! Leave her alone!" he said menacingly, standing protectively before his little sister.
"Whoa! Hey, you want her all for yourself, hero?" asked Bobby, waving the gun in Kevin's face. Kevin stood his ground, staring wildly at the armed punk. Bobby lowered the gun and pointed it at Debby. "You want to fuck her bad, don't you, junior?"
Kevin looked down at his naked young sister and swallowed nervously.
"Come on, kid!" Bobby teased. "You want to fuck the horny little cunt so bad you can taste it, right?!"
Kevin licked his lips and nodded in defeat. He did want his hot, sexy little sister all to himself… to fuck whenever he wanted! Kevin was hooked, and Bobby knew it!
"Okay, junior! I'm gonna give you a break. You two kids wanna fuck so badly? Let's see what you can do… But hold on, I want Red and Daddy Dick here to take a good long look at their own kids fucking!" said Bobby, untying Lisa and Dick. He motioned for the naked parents to join Mandy and Cathy on the bed before signaling Kevin and Debby to resume their incestuous lovemaking. "Okay, hero!" he grinned. "Fuck you hot little sister stupid!"
Kevin fell upon his sister with a vengeance. Bobby had humiliated him, in front of everybody, including his parents… now he was going to show them all!! Spreading his little sister's legs wide, Kevin knelt between her thighs, draping her ankles over his shoulders. Debby's tight, moist little cuntlips glistened wetly in the morning light, gaping open as her brother positioned his fat cockhead once more into the glistening pink slit her tiny blonde pussy.
Debby moaned and looked down between her legs as her brother hunched his lean young hips forward, nudging the fat head of his cock into her tight little fuckhole. As the huge flared knob popped inside, Kevin had the urge to ram his cock down into his little sister's hot, clasping cunt to the balls, but he didn't want to appear to loose it in front of Bobby. Slowly, inch-by-inch he worked his huge, stiff prick between the slippery folds of Debby's sweet young cunt. Debby was panting hard now. She was more than eager for Kevin to fuck her. She didn't care if he was her brother or that her mother and father and three total strangers were watching. She just wanted him to shove his long hard prick into her yearning cunt and fuck her to orgasm.
"Ohhhhh, Kevin! Do it!" she pleaded, finally. "Put it in and fuck me! Fuck me hard like Daddy did last night! Ohhh, pleeeeease! Fuck me!"
His gorgeous little sister begging for his prick was the last straw. Her wanton, lustful pleading drove the excited young boy over the edge of restraint, and, with a loud cry of lust, Kevin lunged his hips forward and down, plunging the full length of his rock-hard cock way up into his sister's belly. Debby's eyes grew wide, then lidded over with lust as she felt her little cunt thrust full of long, thick prick. Her brother's cock seemed every inch as big and fat as her father's had done last night, and the girl knew that she was really going to enjoy fucking her handsome big brother a lot!
