Bobby's cock was almost at full erection now, and Mandy was having great difficulty in fitting it all into her tiny, sucking mouth. He reached down to the girl's crotch and began to rub his fingers up and down the hot, juicy slit between her tight cuntlips. Mandy moaned around his cock and hunched her pussy up against his hand, urging Bobby to stick his fingers in deeper. Bobby slid two fingers up her cunt and rubbed her fat little clit with his thumb. Mandy sucked his cock harder, grinding her cunt eagerly up around his poking digits.
Even after all the fucking the little thirteen-year-old had done in the last twenty-four hours, her cunt still felt as tight as the first time he'd squeezed his big cock into it, back there at the motel. Bobby suddenly had the urge to fuck the cute little kid again. He pulled Mandy's tiny mouth off his prick and lifted her up to straddle his lap, facing away from him. Now he could fuck the little slut and they could both watch his mother getting double-fucked on the bed. Bobby lowered the girl's tiny butt down over his crotch until the head of his cock slid into her tight-lipped little cuntslit.
"Put it in for me, baby," he whispered, nuzzling her creamy neck.
Mandy gripped the youth's huge throbbing erection and lifted her hips a bit, easing his mammoth prick into her eager little fuckhole. The she sat back down again, alternately lifting and lowering her hips in time with Bobby's up and down cock-thrusts. Bobby was staring at his mother's cunt as it slurped back and forth along Kevin's long prick. Kevin's eyes were on Bobby and Mandy. Although Cathy's cunt was a good tight fit around his cock, the boy wanted to try a bit of what Bobby was getting. That cute little thirteen-year-old cunt must be as tight as a fish's asshole, he thought with more than a touch of envy. Kevin stared as little Mandy bounced up and down on Bobby's huge cock, watching her tight, almost hairless little cuntlips grip the other boy's cock-shaft like a vice. 'God, I'd love a piece of that,' he thought, slamming his own cock even harder into Cathy's slurping cunt.
He thought about his sexy little sister and imagined himself fucking her just like Bobby was fucking young Mandy. He'd fucked his mother and now he was fucking this horny convict bitch, maybe he'd get a chance at Mandy or his sister later. With that evil thought, Kevin started to fuck Cathy with a vengeance, ramming his cock really deep. Her asscheeks slapped loudly up against his belly and his balls battered her clit as Kevin stepped up the pace. He wanted to bring the horny bitch off quick so he could get a chance at fucking one of the two youngsters.
Kevin's tactic worked. His extra-hard fucking quickly got Cathy's juices flowing and she was soon on the verge of orgasm. She in turn, stepped up her mouth action on Dick's pistoning prick. The massive pole of flesh was throbbing in her mouth like it was going to explode any minute. All Cathy had to do was suck a little harder and a little faster and she was sure she'd be rewarded with a nice hot load of thick, creamy cum.
She was right. Within seconds, Dick gave a loud cry and grabbed the back of her bobbing head with both hands, emptying his balls into her sucking mouth. Kevin climaxed soon after, filling Cathy's churning cunt with another load of young teenaged sperm. Feeling the two jets of cream enter her body at once was all the horny woman needed to tip her over the edge too. She grabbed Dick's ass and sucked his spurting cock like crazy, all the while grinding her ass and cunt back onto Kevin's squirting young prick.
Bobby watched them come with a smile. Mandy was still bouncing merrily up and down on his cock and the wonderful friction of her tight, slippery young cunt was quickly bringing him to his own peak. Mandy seemed to be able to come forever. He'd counted three climaxes already, now her little cunt was convulsing around his cock again, near squeezing the life out of it. Bobby grabbed her under the ass and began to raise and lower her cunt on his cock, slamming up into the tight clinging little hole at the same time. To the girl, the effect was like getting fucked at twice the normal speed, and she came again on the spot, saturating Bobby's already-glistening cock with another thick load of fragrant girly-cum.
She was whimpering almost incessantly now, her whole body quivering and her cunt convulsing in one continuous orgasm. Bobby felt his balls tighten and that old familiar feeling surge outwards from his loins. He screamed and fucked hard up into Mandy's cunt as he came. Spurt after spurt of hot, thick sperm filled the little girl's cunt and dribbled out onto the sofa forming a creamy-white puddle between Bobby's thighs.
Bobby bit her neck and nibbled her earlobe, whispering incoherent obscenities into her ear as his cock twitched and jerked inside her tightly clasping cunt-sheath. As their climaxes faded, Bobby got to his feet and walked over to where his mother lay between Dick and Kevin.
"Nice fuck, Mom?" he asked, stroking her slime-coated cuntslit.
"Ohhhh, Bobby! Yes, honey! It was wonderful!" moaned Cathy sleepily. "Next time I want you to join me. I wanna fuck three of you at once!"
"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.
