Janie watched as Billy patted Robin on the stomach.
'Okay, now we're going to do it my way,' he said, and he pushed Robin to one side of the bed. 'Come here, Janie.'
Janie hesitated, but then obeyed his command. She lay on her stomach, and Billy centered her in the middle of the bed.
'Now it's your turn, sweetie,' he said, his hands caressing her back, the excitement in her body rising again. Robin watched, but she had different plans.
'I want you to fuck me, Billy like this,' and arched her cunt up to him, her weight on her elbows. Billy could see that she had a good position there; but he didn't want her to have her way. He looked down at his hands, which were now stroking Janie's soft, round buttcheeks, his fingers running up and down her crack as she squirmed.
'Oh, now let's be fair, sister dear. We must take turns.'
Billy was playing with her now, and she didn't like it a bit. Perplexed, she lay there watching Billy turn Janie on as she rubbed her belly on the bed.
He reached under Janie and cupped her large, firm boobs in his hands now, his fingers fondling the taut nipples as his prick grew. Robin reached a hand over and caught his rod, and now it grew in her hands, as if it were being inflated with a pump. Janie was sighing in pleasure, now, as Billy moved his hands from under her and slid them down the curve of her spine, over her slim waist and down to her butt. He moved his head down to her ass, and he licked her gash with his hungry tongue.
Janie was massaging her tits against the sheets she lay on, trying to take some of the ache out of her swollen nipples as Billy tongued her clit. The small bud swelled with his touch, and the juices of Janie's tight little snatch started flowing. Billy dipped a finger deep into her gash, rubbing some of the fluid on her clitoris. Then he licked the juices off her as his little sister moaned for him to fill her with his throbbing cock. Her cunt was wet now, ready for him to fuck.
With his strong hands he spread her legs apart more, so that he could enter her tight hole easily. He brought his enormous tool close to her box and with the head of his prick he touched her clitoris again, bringing great tremors of pleasure throughout her delicate body. Her nipples rubbed hard against the sheets as he entered her from behind, cautiously, for this was the first time he'd ever screwed a woman from the back. Her legs eased themselves open more as his great shaft entered the folds of her cunt, rubbing against her juicy walls as his shaft found its home inside of her.
Robin couldn't stand to watch any more; she was getting hornier by the minute. She eased herself on top of Billy, then slid back over his muscular back and found his asshole. While Billy pierced Janie's cunt from the back, Robin ran her fingers lightly over his butt and into his bung, heightening his sensations even more. He felt her fingers jam up into his hairy asshole, moving deep inside of him now, giving him a sense of what it was like to be a woman and have a cock inside.
Janie was going wild now, because she was positioned in such a way that Billy's pulsating cock was not only plunging deep inside her cunt, but was also massaging her clitoris as Billy fucked faster and faster in and out of her precious little pussy. Her hands clawed at the sheets as she felt herself being taken away into the outer spaces of sexual pleasures. She was coming now, and she screamed aloud as she climaxed, her clitoris on fire and her legs dosing around Billy's body to encompass his large prick inside her spanning twat. She'd never felt anything like it before, as he fucked her faster and faster, pressing all his might inside her cunt and moving from side to side.
But Billy wasn't near climaxing, since he'd already come many times that day, so he kept humping Janie as hard as he could while Robin licked him asshole. Her tongue was running wildly in and out of his bung as she turned his asshole into a tunnel of ecstasy.
Then Robin's hands were around his waist, squeezing him tight, feeling his muscles, as his sphincter contracted around her fingers that were jammed up into his hole. His ass muscles squeezed on her finger, then loosened, then all of a sudden she'd see his buttcheeks contract again and her fingers were again, wrapped by his sphincter.
Janie lay still now, although moaning in delight as Billy kept screwing her, rubbing his tremendous click against her clitoris, her bud becoming erect again. She began grinding her crotch once more, trying to reach that point once again when the entire world was one of sensual pleasure.
Billy fucked and fucked, the perspiration pouring down from his forehead as he kissed at the back of his little sister's neck. He wondered how long he could go on fucking her without coming. But it didn't matter, because now Janie was climaxing again, and she was screaming.
'Oh Billy, that's it! Harder! Harder!'
She was desperate for a breath. Billy could feel all the liquids in her cunt boiling over, and his dong swam in a pool of her, womanly juices. But the screams from Janie made Robin jealous, and she rammed her fingers up into his asshole as far as she could, harder now, trying to hurt him as a sort of revenge for bringing Janie to a climax but not her.
Janie was screaming like a hurt animal as she came again, her hot juices flowing out of her throbbing cunt as he kept pushing his rod deep inside her hole. Once again, she was being taken to that world where her whole body vibrated. She couldn't take it any more, and before Billy could come, she pulled herself up, denying her cunt of his anxious and swollen prick. She lay there exhausted, moaning, lying in another world apart from Robin and Billy.
Robin saw Janie's move and knew it could be her turn now. Billy's rod was enormous, waiting to be stuck into one of their tight little pussies, and Robin wanted it to be hers. She lay down on his thick back, her boobs heaving against him, her hands fucking under him and finding his pecker.
'Fuck me now,' she whispered in his ear. Then she blew a stream of air into his bar, driving him up the wall. He rolled over, Robin following him, so that now she was lying on her back. Her legs opened for him, ready to wrap themselves around his body as her snatch took his dick inside of her.
Billy kissed her for a moment, but Robin was so wet now, so ready for him, she couldn't wait. Her blind hand reached down and curled around his pounding spear, guiding it to that hole between her luscious thighs.
'Fuck me now, Billy!' she cried, holding his prick hard in her hands as he towered over her. His eyes seemed to be losing their strength now, and, after exchanging looks, her anxious hand guided the throbbing cock inside her snatch. Her knees arched as his full weight came down upon her, and she could feel his butt grinding away. He was driving his rod deeper into her cunt than he'd ever done before, just the way she wanted. She wanted his cock to become part of her body. She wanted to devour it right inside of her, to swallow it with her cunt.
'Harder!' she cried as she felt herself nearing her climax. Now she was fucking her way, on her back.
Robin propped herself up on her elbows and arched her entire crotch up to him as he dug deep into her cunt, into depths, never before reached by any cock.
'AAAAAHHHH!' she screamed, then again, and again, over and over as he pierced her twat as far as he could, his full weight upon her supple body as her aching pussy begged his dick to come in farther.
Billy could feel his juices getting ready to explode, his body shaking as he thrust into her again and again, his full weight driving into her tight pussy. He stretched from side to side, forcing a different sound from her screaming mouth every time. His body was vibrating sensationally now, his dick seemingly as big as his leg, pushing and thrusting inside her warm cunt walls.
Robin, too, was shuddering as she squeezed his cock with her cunt, letting loose as it pulled out, then tightening up on it again as he thrust.
'Help!' she cried as her juices flowed hotly. She was being fucked just the way she wanted. But her words made Billy stir his rod inside her pussy even more, for he wanted to rip her bitchy little cunt apart. He shot in her, then, thrusting forward over and over, he shot in her again, his cum bouncing off the tender walls in her cunt, each wad of cum producing electrical thrills that shook her entire body. He came in her for what seemed like hours, her delightful pussy juice now flowing hard around his prick. Finally it was over, and her elbows collapsed back onto the bed, her pelvis also falling with her, and Billy's muscular body falling on hers. Her arms reached around him, but she was too weak to even do that, and her arms fell limply to the bed.
Billy was exhausted, too, but he wanted to get Robin one last time. He gritted his teeth, moved out so that the head of his dick was just at her wet cunt mouth, then, gathering his strength, he let out a scream and thrust into her one last time.
