to dress themselves. Billy sipped at a cold Coke as he sat there, wondering about his sisters, if they'd ever tell their parents, if he'd ever be able to spend another weekend with them. Then a great fear overtook him, fear that these moments would never come again. It had just so happened that both of their boy friends were gone this weekend, that he had to stay with them – it all seemed coincidental to him. He looked at the wall that separated the girls' bedroom from where he was, imagining their lovely bodies behind it. He wanted to spend the whole day in bed with them, to fuck them till they were sore, till he couldn't get a hard-on any more. He had twenty-one years of waiting, and now that he'd had a taste, he never wanted to go thirsty again.
He could feel his prick become erect as he sat there dreaming about what was behind those two walls. His trunks swelled, and he had to adjust his cock in a different position because it was very uncomfortable as he sat there. He wished he could convey his thoughts to his sisters, and all that prevented him from doing so was his own mind. All he had to do was walk into their bedroom. He eyed the closed door that led to their room, thinking a moment. He realized how short time was and started towards the bedroom.
As he opened the door, he could hear the shower water running, so he knew one of them must be in there. He walked to the bedroom, and he could see Robin dressing herself, her back to him, standing only in her silky white lace panties as she threw a robe around herself. Her gorgeous body was covered now as Billy neared her.
'What all do you have to do today?' he blurted out. She turned to him, surprised that he was there.
'Someone really ought to teach you to knock,' she told him, then walked to the dresser, taking the brush and running it through her streaming hair. 'Aren't you going to get dressed and come with us, big brother?'
'Well, where exactly are we going?'
'Janie and I have some things to do – the laundry, pick some clothes up. Then we have to go see the family tonight. They're making dinner for all of us.'
'Who? Mother?'
'Of course. We're supposed to be there at six.'
Billy sat down. He pondered a minute, thinking how they could avoid such an invitation. He was having too much fun right here in the apartment. He could feel his erect cock aching for his sisters now. He just wanted to see their lovely bodies again, to run his hands over their soft skin, then slip his cock into the twitching cunts. He wanted to go over to Robin and slip the bathrobe off her, but he knew he had to use more sense than that. But he could feel himself losing control as he watched Robin comb her lovely hair.
'I don't want to go over there tonight. Do you?'
'It's not whether we want to, it's that we have to, Billy. Besides, they want to see you while you're in town.'
Billy knew he was trapped. He knew he wouldn't get another chance to ball his sisters unless he acted quickly. He walked over to Robin, standing behind her, and placed his strong hands on her waist.
'What axe you doing?' she asked, startled by his move. 'Can't you ever think about anything except sex?'
The words struck a hard note in Billy's ear, and as his hands tightened around Robin's slender waist, he knew she was right. All he ever did think about was sex! But he didn't know what to do about it; he just couldn't control himself. When he got around a pretty girl, he wanted to take her pants off and stick his cock inside her, fuck her all night long. Maybe it was because he'd always been too scared to try to lay a girl, maybe because he'd never screwed all these years. But now he knew what fucking was like and how to do it. And he wanted to do it some more. But Robin was getting annoyed with him as he pinched her waist through her robe.
'Look, leave me alone for a while, all right?' she said, thinking he was only playing. He wasn't. His head lowered to her neck and he began kissing her soft skin.
'You don't want to go out today, do you?'
Robin was really getting annoyed now as she jerked her head, frying to pull away from him.
'You're really crazy, you know that?'
Billy ignored her words, his mind bent on slipping the robe off her back and feeling her soft warm flesh again.
'Wouldn't you much rather feel my big cock inside your pussy, sister dear?'
Robin stopped brushing her hair as the very sound of the words 'cock' and 'pussy' started to arouse her. When he said the word 'cock', she could imagine his tremendous dick sticking up in front of her, then inside of her, his powerful rod massaging her aching cunt. The dream was exciting her, and she could feel his hands tighten around her waist as he kissed her neck hotly again. She could feel herself losing control now, but she felt she had to stop him.
'We really shouldn't, Billy,' she whispered, but he paid no heed to her and continued working away at her neck. His hands reached up to her neck and pushed the collar of her robe down, so now he could kiss the nape of her neck and the top of her soft back. Her tender flesh quivered when his tongue reached her dry skin, and she could feel his heat reaching her body now.
'Billy!' she cried faintly, but now she was aroused, the fluids in her cunt beginning to stir as he ran his hands over her delicate back, caressing her buttcheeks through the cotton robe. She whispered 'Billy' one more time as he turned her to him, his hands resting on her shoulders. Then his mouth drew up to hers, and soon their hot tongues were racing inside of each other's mouths, kindling hot passion within both of them now.
His hands slid down to the belt that closed her robe over her lovely body, his fingers pulling at the ties. The robe hung open, revealing the rise of her tits and the white lacy panties that she had on. The smell of perfume filled his nostrils as her supple body came within his reach now. Billy could feel his prick swelling to enormous proportions as he admired his sister's lovely body, and as his eyes looked up at her, he could see her looking at his bulging trunks, her mouth hanging open as she marveled at his hugely pulsing boner.
His finger traced over her soft panties, running down to the triangular muff that showed through the silken panties, then up in a circle to her belly, ending in the valley between her ripe nipples. His sister was so beautiful as she stood, before him, waiting now to be taken by his strong, powerful hands. He reached inside her robe, touching her shoulders lightly, and as his mouth sucked at her lips again, he slipped the robe over her shoulders, down her arms, letting the garment fall to the floor. She stood before him now only in her white panties as he kissed her hard.
Robin could feel herself losing control now as her hands reached around him. Her arms held him tight to her, her mouth kissing him hard as his hands clawed at her tender back. Her breathing increased rapidly now as he smothered her with his kisses as his hands slid down to caress her butt. Her ass was swaying now, grinding away at his touch as his fingers inched inside the lace that covered her. He stretched the material back a bit, his hands dipping down into her crack, then his hands ran back up the sides of her rib cage, setting her soft flesh afire with each touch.
She could feel her body weaken as his fingers touched her taut nipples, pinching them in his demanding fingers, titillating her knobs and sending wild vibrations through her boobs. She could feel her cunt throbbing in excitement now, and her juice was moistening the panties that touched her silken crotch.
'Billy, Billy!' her voice echoed, and he knew that he had her now, that it was just a matter of time before he would stick his colossal cock inside her meaty pussy. Bat be wanted to get Janie into it, too, because two was always better than one. He could hear the shower stop as he continued to run his hot fingers over Robin's supple body, bringing beads of sweat to her forehead again, and he knew that in a moment Janie, too, would be there.
He put his hands around the lace-covered buttcheeks of his little sister again, rubbing her very gently, and pulled her over to the bed. Turning her, he gently eased her down to the bed, so that she was lying on her back, her eyes closed and head bobbing, waiting for him to fuck her.
The bathroom door opened and out walked Janie. She was protected only by a towel she had wrapped around her wet body, her hair wet and stringy as she jumped at the sight of Robin and her brother.
'I thought we were going out!' she said, standing there, not knowing whether to join them or leave them. She turned to go, but Billy stopped her.
'Don't leave. Come join us,' he said, trying to catch his breath.
Janie hesitated a moment, uncertain of what to do.
'Come on,' Robin added, and this made Janie feel better. Her eyes caught sight of Billy's swollen trunks, his rod sticking out clearly against the soft material. Her sister was panting, and the sound of her breath and the sight of Billy's enormous hard-on made her stay. She moved cautiously towards the bed, not knowing what to expect or
