things that you have no business sticking your nose into…'
Then she leaned forward slightly, looking down into his eyes and added, very softly, '… although that might be kind of fun.'
Bill's cock gave a lurch at the blatant invitation in her eyes, but he swallowed hard yet again and rolled over with his back to her. 'Turn out the light when you're ready,' he gasped.
'Okay,' Gwen said, turning back to her bed and starting to unbelt the robe. She knew she had him just where she wanted him. She had seen the sudden fluttering of the sheets over his groin just before he turned away. This was going to be even easier than her biology professor had been!
'I've started sleeping in the nude since I went off to college,' she said in a casual tone. 'Hope that doesn't bother you.'
Bill's eyes opened wide with surprise, and small beads of sweat broke out on his forehead. He looked up toward the dark window and watched as if in a mirror while his sister undid the tie on her robe. 'Uh, no… no problem. I… I sleep in the raw, too. It's pretty hot at this end of the house in the Spring.'
'Yeah, I remember,' she said. Knowing he was watching her in the window, she let the belt fall to the floor, then with a slight movement of her shoulders shrugged off the robe, suddenly revealing her entire body. She had to suppress a sudden giggle when she saw his whole form stiffen under the sheets and heard his sharp gasp. Just the kind of reaction she always got from men!
Bill watched with wide eyes as Gwen proceeded to stretch her arms high over her head, pulling her lush breasts up with the motion so that they hung full and firm on her torso, the dark nipples pointing toward the ceiling as well. His eyes darted all over her exposed body as it was dimly reflected in the darkened window, his cock continuing to throb and jerk uncontrollably at the sight of his sister's bare body.
When she brought her hands down and lightly stroked her tits, then pinched the nipples up hard with her eyes closed in ecstasy, Bill thought he was going to blow his wad right there.
Gwen figured she had posed long enough without making it too obvious that she knew he was watching. She leaned over to give him a last shot at her pert ass as she turned off the lamp between their beds, then slid under the sheets of her own bed.
Bill squirmed uncomfortably in his bed, tossing and turning, his huge erection throbbing unmercifully, but also afraid to jerk off for fear his sister would hear him. God! he thought, she's incredible-looking!
In his mind's eye he could still see her beautiful body, the proud, rounded tits and long legs of this gorgeous young woman, totally nude in a bed not three feet away from him, and totally beyond his reach. It was his own sister, he berated himself over and over. He had to stop thinking about her this way – but still his cock throbbed its reminder.
Finally, after a fitful hour of shifting in his bed, Bill drifted off into a troubled sleep, his youthful cock still holding its painful erection. He was dreaming of women, all kinds of women, begging him to fuck them, throwing themselves at his feet. But everytime he reached for them, their faces would shift and melt, then change into Gwen's.
He woke up suddenly, confused and disoriented. Something felt strange.
He moved one stiff leg slightly, then suddenly froze. The pressure of warm soft flesh pressed along his thigh, and then he became aware of that same feeling pressing all along the side of his body. The room was pitch-black, but he could smell the sweet perfume of her hair, and feel a few stray strands tickling his face.
Am I still dreaming? he wondered in panic. He couldn't see a thing, but he was now aware as well of her gentle breathing but inches away. He gasped slightly at the full realization that his sister was in bed with him, totally nude and virtually in his arms. His cock, which had finally begun to droop as he slept, leaped back to full, pulsing erection.
Gwen heard his low gasp. 'Are you awake, Billy?' she asked softly, raising one hand and gently touching his cheek.
'I didn't mean to wake you,' she whispered. 'I really feel kind of silly, but I… I had a nightmare, and… well… can I hold on to you for a while? Just hug me and I'll feel okay. It's not cold, but I feel cold.' Gwen held her breath, waiting for his reaction. She had gone as far as she could now, and if he rejected her she would be crushed.
'Okay,' he said, so softly that she almost missed it; then she felt his arms come up and move around her back, pulling her closer. Gwen wanted to cry out in triumph with her brother's arms now holding her nude body. She wanted to dive immediately for his cock, get her hands and her lips on his massive prick, but knew she had to keep moving slowly, not wanting to ruin it at all just at the last moment.
Bill's heart was beating a mile a minute as he held his naked sister.
She was trembling slightly, and smelled so sweet. Her large breasts pressed against his chest, her head resting on the pillow so close that he could feel her warm breath on his face. He felt a shiver pass through him as she moved her legs and her incredibly soft pubic hair grazed over his thigh.
She just wants comforting from me, he figured sternly to himself, but his cock was stirring, and a heavy, surging pressure was building in his balls.
Gwen kept making small, seemingly accidental brushes of her cunt hairs over his muscular thighs, knowing that her creaming pussy so close to his cock was an incredible turn-on. She kept her stomach back so as not to touch his cock, still slowly letting the seduction move along, not wanting to rush him. But she could feel little drops of sweat breaking out on her brow as she held back, her body shivering with sexual frustration.
Bill moved his hands slowly over her back and arms, feeling her shiver.
Maybe she really is cold, he thought. He tried to hold his breath and think of other things, willing his cock to shrink, but it did no good.
There was no way to ignore the sweet, female scent of her skin and hair, and as she snuggled in closer to him, he felt a slight dampness on his legs where her muff gently touched. He prayed she couldn't press in too close and feel his heavy prick, find out he was aroused. Prayed she wouldn't, but at the same time had to admit he hoped she might!
'Are… are you feeling better now, Sis?' he whispered in a voice that was more of a croak from his dry throat.
'Oh, yes,' she sighed happily. 'I feel nice and warm now.' She hugged in even closer to him, resting one hand lightly on his stomach as if by accident while she moved to get more comfortable. 'In fact,' she cooed,
'I'm almost burning up!'
And then, throwing all caution to the wind, Gwen reached straight for her brother's groin, wrapping her hand tightly around his throbbing cock.
'Oh, God, it feels so big!' she moaned, pulling on his long meat shaft.
A gasp of pleasure burst from Bill's mouth as he felt her expertly jerk and tug on his cock. His mind was filled with nothing now but the thought of sex, his head with the smell and feel of this luscious female in his arms. Sister or not, he had to fuck her!
His trembling hands grasped at her breasts, soft and lush, the nipples growing hard under his fingertips. But even as he squeezed the hot flesh he knew she needed a stronger caress. Gwen was rubbing her wet cunt against his thighs, her moist pubic hairs scrubbing his skin.
'Feel me, too, Billy!' she moaned, humping at him eagerly with her snatch. He slid his hand down to feel the soft bush of her muff, and she spread her long legs for him, pushing her groin upward. And then, Bill was fingering his sister's hot, wet pussy-flesh for the first time, playing with the forbidden portals of her cunt. Gwen moaned and pushed up against his stroking hand, and he thrust two fingers straight into her dripping twat hole.
'Fuck me! Fuck me!!' she begged him, rolling her head from side to side, riding his fucking fingers. 'I'm so fucking hot I can't stand it!
Fuck me, Billy!!'
They were both so hot and turned-on that there was no need for any foreplay. Bill's cock was close to exploding already, while Gwen's cunt was drenched with her own juices, ready for his first penetration. Bill lifted her upper leg and they rolled to face each other, his fingers sinking into her flesh, pulling her closer. Gwen tightened her grip on her brother's cock and guided the stiff, pulsing pole of meat into her wet cunt. The fat crown of his prick pried swiftly through her juicy twat lips and dug deep into her clasping pussy.
'Yeah! Oh, yeah!' Bill sighed as his cock was enveloped in his sister's hot snatch. He reached around her body and grabbed her asscheeks, pulling her in tightly to him as he slid his prick into her hot hole.
In seconds he was urgently ramming his entire eight inches of hard cock deeply in and out, and Gwen was
