"Jesus! You mean it, Mom?!" Bobby grinned. The thought of triple fucking his mother with two other guys was a tremendous turn on.
"Sure, honey!" replied Cathy fisting her son's sticky cock. "If my poor little baby feels up to it, that is."
"Shit, Mom! I hope you don't mean right now! I just fucked Mandy!"
"Don't worry, lover," grinned Cathy, looking down at Kevin and Dick. "These two are pooped now as well, so it'll have to be later."
"Okay, Mom, you're on! Now, let's eat!"
Bobby helped his mother to her feet and they headed for the kitchen, totally ignoring Kevin and Dick who were still flaked out on the bed. Buy the time they had all eaten, exhaustion began to set in and they made plans for bed. Bobby knew that he and his mother were so tired that they couldn't take turns at guarding their prisoners, so he decided to tie them up in pairs. He paired Lisa with her husband, and Kevin with his sister. Tying them together facing each other, still naked. He placed Kevin and Debby lying on their sides on the sofa and Lisa and Dick on a spare mattress on the floor beside them.
He ignored their complaints and retired to the bed with where Mandy and his mother were already fast asleep. Crawling in between them, Bobby put the gun under his pillow and snuggled up against his mother. He remembered her promise to let him join in a four-way fuck with her and he drifted off to sleep with a sly smile on his face.
As usual, Kevin awoke next morning with a hard-on. Except this time, it was wedged firmly between his little sister's naked thighs. She was still asleep, her cute young face only inches from his own. Kevin tried to move, and found that the ropes had loosened a little during the night. He looked around and saw that all the others, even his parents were still fast asleep. He moved his hips slightly to try and relieve the pressure on his trapped prick, but as he did so, Debby lifted her leg over his in her sleep and his cock slid right against her warm little pussy.
Kevin couldn't help himself, his sister's gorgeous hard little tits were pressed tantalizingly against his chest and her young cunt against his prick felt so inviting. He moved his own hips forward and bunched his ass, running the tip of his cock along the length of his sister's hot, moist cuntslit. Debby squirmed in her sleep, but didn't move away. If anything she seemed to be trying to get more contact between her cunt and her brother's cock-tip. Then, when she lifted her leg and hunched her crotch forward against his prick, Kevin was sure she was doing it on purpose. But she looked like she was asleep.
Kevin decided to throw caution to the wind. He had a hard-on that just wasn't going to quit unless he did something about and sister or not, Debby was in the right place at the right time. He tried to reach down between her thighs, but the ropes prevented him. Instead he placed his hand on her tight little ass and ground his cock meaningfully against her cunt, hoping his sister would lift her leg a bit so he could get his cockhead wedged properly into her cunthole. Once that happened, she was as good as fucked, he thought evily.
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.
