Robin could feel the hatred in his voice, and it scared her so much she wanted to do everything she could just so he wouldn't hurt her.
'Now come over here.'
Robin moved at his command.
'Now put your pussy on my lips. Now!' he demanded. Slowly Robin squatted down to him, lowering her cunt mound to his lips. Billy could see her wet slit come down to him, and he could smell her musky sex. Then his tongue darted out into her tender folds, sending tingling sensations through her body. He sucked at his sister's box for a moment, but he wasn't satisfied.
'Let's go in your bedroom,' he said, and his hands pushed her thighs up from him so he could get up.
'But Janie will be home soon,' she protested.
'Don't you argue with me, you prick-teaser. Now get in that bedroom!'
Robin knew that by the tone of his voice she'd better move, so she softly stepped into her bedroom. Nervous, she stood in the middle of the room till he came in.
'Now get on the bed.'
Billy stood there, his long, thick cock dangling between his wonderfully strong thighs, watching his sister as she climbed onto the bed. Her magnificent tits bounced on her chest as she moved. He'd never seen such large tits, and her nipples were so inviting he could have sucked on them all day.
Robin was tense as she lay on the bed, reclining on her back and propping herself up on her elbows, so that her blonde-haired snatch pouted up at him. Her hand wandered momentarily up to her nipples, rubbing them softly, and Billy could see the tips rise and harden as she fingered them. He studied her lovely body, the shining mountain at fuzz that covered her delicious crotch, the curves of her legs down to her toes, the soft valley around her belly it all looked so inviting to him. He realized now how much of a woman his little sister really was.
Robin was looking at him now as he stood there before her. He was such a man, she thought, so masculine and well-built. She marveled at the muscles in his arms and stomach, at how solid his entire body was. And his cock! She'd never seen one bigger, never seen one more eager to please. Maybe he had been a virgin before today, but so what? She caught a final glimpse of his strong thighs and his big cock before he moved again. Billy went over to her dresser and found a pack of cigarettes. He took them over to his little sister.
'Here, light this,' he said, and stuck a cigarette in his mouth.
'I don't have any matches,' she replied.
'Then get some.'
Robin looked at him, then got up and walked over to her dresser, her ass bumping from side to side as she walked. She took a box of matches from one of the drawers, then tame back to the bed. She lit his cigarette.
'Here,' he said and stuck the cigarette out for her.
'No thanks. I don't care for one new,' she said, but Billy wouldn't take no for an answer now. He was a tower of strength as he sat next to her, knowing that he could perform any sexual act he could dream of, knowing his gorgeous cock could satisfy any woman, let alone his little sister. He stuck the cigarette in her face, and she took it, puffing on it. He raised his head to hers and sucked on her lips, drawing the smoke from her mouth into his. He moved his head away, then exhaled the smoke, smiling as he did so.
'Tell me about your boy friend,' he said.
'What do you want to know? He's just an ordinary guy, you know.' She took another drag on the cigarette, and he watched as her lips circled the white filter, picturing her lips wrapping around his throbbing prick. She blew the smoke out in his face, licking her upper lip with her moist tongue.
'Do you fuck him much?' he asked, desperately curious about her man.
'All the time!' she shot back at him. 'I really enjoy balling him.'
'What's that supposed to mean?' he asked.
'It means that I just love to feel his cock inside me. It means I can hardly wait to feel his jism on my tongue. It means I love to taste his dick.'
'Is he as good as me?'
'What?'
'I said is he as good a fuck as me?'
Robin laughed derisively. 'You don't even come close,' she said. But she was lying, for she'd never taken a cock like her brother's before, nor had she ever found a guy who could shoot so many times without stopping. She heped by prodding him he'd respond with more passion for, her youthful body.
Billy took the cigarette put of his sister's hand and crushed it in the ashtray next to the bed. He lowered his lips to her belly, sucking her navel, blowing on it, and licking it clean with his saliva.
He felt her breathing heavily again as her belly started a rotating motion. His longing hands reached up and touched her nipples, and he felt them come to life in his fingertips as he pinched and pulled at them fiercely.
Then he directed his lips farther down her belly, over her warm flesh, to the fur of her sweet box. His tongue played in her hair, and now he slid his hands under her buttcheeks, tickling her ass. Her breathing became heavier. Billy lowered his mouth, and his hungry tongue found her clitoris. He licked at her twat, filling her with desire once again.
'Fuck me again, big brother,' she sighed, but this time Robin wasn't going to get her way.
'Let's see how close I can come,' he snarled at her.
Robin's eyes opened wide as her brother stopped lapping at her oozing gash. She watched his muscular arms as they took hold of her by her slim waist and turned her on her stomach. He was brushing his fingers lightly against her pubes, just giving her the most fleeting of touches, and Robin rubbed her belly on the bed to ease some of the pressure in her unfulfilled body.
'Rape me, Billy, rape me!' she begged him.
Billy reached over to her waist again, this time hoisting her up on her knees. She spread her arms down on the bed, so that now she was resting on all fours, just the way he wanted it. Her inviting ass was stating him in the face as she wafted.
Robin was still a bit tense, wondering what he was going to do. He's going to screw me from the back, she thought to herself as she felt his hands running under her belly, down over her cunt fur, and up to her ass.
Billy grabbed her asscheeks and spread them apart, so he could see up her butthole clearly. He lowered his burning lips to her rim and started licking, furiously licking the inside of her ass, teasing her bung, and running his hot tongue up and down her rim.
Robin had never felt such a sensation before; for the first time she was experiencing a feeling she never dreamed possible. He was sucking and licking her asshole, darting his tongue up into her butt while his hand massaged her throbbing clitoris. She was getting dizzy from it all, panting and breathing hard.
Robin felt his tongue stop in her ass, then withdraw back into his mouth. He spread her cheeks even wider now, and pressed his mouth to her asshole. Then he breathed deep, and blew a sharp, cool stream of air right up her ass, stimulating every nerve in her butt. Again he shot a breath of cool air up her asshole, and the sensation drove her out of control.
'I'm coming, I'm coming again!' she exclaimed.
As she trembled in front of him; Billy moved his knees a bit closer to her, lining up his dick with her asshole.
'Fuck me, Billy, please!' she groaned as her lovely body shuddered furiously from the stream of air he had blown inside her ass.
He was getting more excited now, and his cock was pounding hard. He grabbed her waist, pulling her to him, and his pulsating prickhead found her bung. Slowly he shoved his tremendous shaft up her asshole.
'Billy!' she cried, but the ecstasy of his gigantic cock moving up her ass was too much for her. She felt her shitter stretch as he pushed his pounding rod into her tight ass. Then he began fucking her butt, pulling out and shoving back in as far as he possibly could. Billy started moaning loudly as he felt himself getting ready to climax. His hands reached under her and grabbed her nipples, and he squeezed them roughly, needing something to hold onto.
Robin, too, was on the brink of a come, and he shot into her ass, she felt sensational. Her bung tightened around his huge dick as she spasmed in sexual pleasure, her hot juices spilling out of her moist box and dripping onto the bed. Billy came with a fury, jabbing her bowels with his sword harder with every shot. She cried out in ecstasy as her tight ass ate up his swollen cock. Billy gave her one final thrust, digging deep inside her ass,
