about Erica's bitchiness, how she had not only been fucking around behind his back, but also doing it with one of his best friends. He launched into a long, morose, bitter, increasingly tipsy tirade, aid Mona listened dutifully, drinking along with him and nodding at the right moments.
The Scotch made her warm and tingly, but as time wore on she began to wish that her bathrobe was made out of some other fabric than satin, because it was so slippery. It was hard enough to keep the skirts over her thighs and knees, but even worse was the constantly loosening sash. Whenever she moved it loosened more, and her firm out thrusting breasts pushed against the front part of the robe until the neck-lapels were gaping wider and wider, revealing more and more of her tits.
And there was the delicious sensation of the cool slippery satin against her warm, tingling skin. It rasped softly across her sensitive nipples, rustled smoothly against her inner thighs. In front of her brother she felt vow modest, but at the same time remarkably relaxed, especially since he was so obsessed by his wife's infidelity that he hardly paid her any attention.
After a while, as Steve droned on about Erica, Mona didn't really hear him any mow. She found herself dreamily remembering herself and her brother as kids. Vague images floated in her mind. But out of them, one peculiarly exciting one emerged.
One afternoon when she was about eighteen she had walked past his bedroom and there he was, sitting on the edge of his bed, facing the open door. His thighs were spread and the long thick tube of his cock hung there in all of his glory for her to see.
Mona had stopped and stared at his large prick until it began to swell and rise and thump with blood. Then, with a nervous giggle and a very hot face, she had turned and fled down the hall.
Now Mona felt the same guilty fluttering and sharp tremors of heat in her body that she'd felt then. She squirmed and felt dazed and too warm, and she noticed that Steve's droning voice had stopped.
Then she saw his eyes. He was sunk in some kind of trance too. He was staring at her, not at her face, but lower. And she glanced down and saw that the sash of her bathrobe had come completely undone. The robe had parted, and her body was exposed from her throat to the fringe of her pubic hair.
Rushing with embarrassment, she pulled the robe shut. 'Oh, I… I don't know what happened to me!'
'Don't,' Steve said quietly.
'Steve!' Mona said, as if to shame him. But her voice was not convincing. 'Please don't.'
'Steve, I'm your sister.' Across her mind flashed the image of his thick cock thumping and filling with blood. What was his prick like now that he was a man? The thought horrified her. What am I thinking like that for! I've got to stop it! He's got to stop it!
Steve shook his bond, then he grinned at her. 'That's right, you are. I guess I almost forgot. For a minute there I… well, I was remembering that time I stole your bikini top.'
Mona blushed hotly. It was another think she had forgotten, the time he had swiped her bra in a swimming pool just to get a glimpse of her ripe young breasts.
'I'll never forget it. You were beautiful even then, but now…'
'Steve, I think we'd better change the subject.' Mona's flesh was hot and prickly, her mind in a confused whirl.
She felt so close to something dangerous that she didn't know quite what to do. The best thing, she figured, was simply to take charge right now, not to let it happen again.
She tightened the sash of her robe and stood up. 'I think I'd better change, get into something else. Don't you?'
'No.' He grinned, his eyes murky, friendly but deadly serious.
'I moan… we'll both feel better if there isn't any chance of…'
'Of what?'
'You know very well what.' She looked down at him and wondered how he could be so calm about it. She was breathing so hard that her tits were heaving, which only made him more interested in the sight of her plump nipples floating under the shiny satin.
Steve's eyes seemed to flicker. 'Tell you what. Look at it this way. If you're my sister, and I'm your brother, then we're both really the same flesh, right? We came from the same mother, we've got the same genes and tissues and…'
He fell silent, and they both laughed nervously. 'Well, I guess I've heard everything now,' Mona said, trying to match his calm irony.
'No, you haven't,' Steve said. 'Why don't you show me yourself just once more, before you change? Just for family's sake.'
'Why should it?' My God! Mona thought. What am I doing? I'm teasing him, I'm just making it worse!
'Because I want to see you. You're lovely.'
'Lovelier than Erica?' she whispered softly, growing morn ashamed of herself by the second. For the first time she let her eyes wander to the crotch of his pants and she saw the huge swelling there.
'Lovelier than anybody. I swear.'
'All you want to do is see me?'
'That's all.'
'You won't touch?'
Steve gave her a sardonic smile, as if to warn her that they weren't kids anymore. 'Promise,' he said.
'I don't believe you,' she murmured. 'I don't believe you for a minute… not for a minute…'
But her fingers were fiddling with the knot of her sash, tugging it, and pulling the slippery fabric loose. She wanted to show him her body, her whole body this time, not just a part of it. She wanted to pose before as she had earlier posed before the mirror, to show him everything.
She knew it was horribly wrong to be doing this, but the impulse was overwhelming. In the split second it took her to pull open the robe and slip it off her shoulders, showing him for the tint time every delectable inch of her supple nude body, she knew there was no going back.
They would fuck. And she would let it happen. She would invite it, though she would also fight it with every ounce of her nerve because somehow she was not supposed to let it happen, even though her cunt and tits seethed and ached for him.
Steve scrutinized her naked body, now glowing and warm and flushed with the fires of her shame and excitement. Slowly she pirouetted in front of him, showing him her ass. Her firm breasts swayed and bobbed pertly, her long puffy nipples already half-erect before his mesmerized gaze.
'You like?' she whispered, teasing him, unable to stop herself.
Steve nodded and licked his lips.
She stroked the smooth undersides of her creamy tits and raised them. Steve's harsh breath seemed to be clawing its way out of his throat. And that sound excited Mona further.
She came closer to him, closer, watching his crazed eyes devour her succulent tits. She watched his eyes so closely that she squealed with sharp surprise when she suddenly felt his hands gripping the backs of her thighs, pulling her forward strongly. He squeezed her asscheeks as he pushed his face into her stomach and his tongue dithered into her navel.
'Ohh! Ohhh?' she yelped, wriggling out of his grasp.
She jumped away from him, trying to act shocked, but the feel of his tongue in her navel and his fingers digging passionately into her ass-flesh had made her reel with hot thrills. 'Oh Steve,' she said, half mocking him, 'you promised you wouldn't touch! You promised!'
Steve managed to grin again. 'Couldn't help myself,' he said hoarsely.
'Now Steve… Steve!' she whimpered softly, backing away, as her brother stood up from his chair, bending slightly at the waist to ease the pressure on his bulging, pants-cramped prick.
God, God, she thought, I should stop it now, before it's too late! I can't let him fuck me!
Slowly, deliberately unbuckling his belt, Steve walked toward her.
'Mona… Mona, I can't stop myself,' he murmured, shaking his head, his eyes racing over her nakedness.
She kept backing any (win him. 'Steve, you know we can't.'
'Yes, we can.' He backed her against the wall. His hands cupped her feverish face, his lips came down toward him.
