She wants to play hard, I can play hard.I use my two hands and get her nipples, rolling them forcefully in my hands, pinching them, flicking them. Her...eyes open wider at the assault, but she knows that she has me in a tight position, with my lower lip stuck between her teeth. I can’t move, I can’t fuck her, it will hurt if I do, I’m not ready to make that sacrifice yet. But, I haven’t played my last card yet. I move my left hand to her clit and play rough with her. I see that she wavers a. I said "But, your my sister, and, and, you already have watched me, and, and, your my fucking sister!!" She tells me to relax, and that it's ok. She sits back in the chair and pouts, folding her arms across her chest. That's when I notice, for the first time, that all she is wearing is one of my old white tee shirts. Worn and almost in tatters, I can see her two huge nipples poking up under it. It is short, so short, I can also see that it barley covers her, well, it doesn't. I can tell. Desire turns to need as the realisation of you fills me. I draw closer as I start the slow seduction of your desire.I kiss the back of your neck, softly, almost invisibly and your breathing alters, I watch in the dark as your body arouses slowly. More kisses to your neck, behind your ear, and you moan as without realising it, your back arches almost imperceptively as my cock gets embraced in increasing sensual pressure by your gorgeous ass. I feel the ache of emerging desire light your nerves. Getting stuck up in these mountains in the summer wasn't fun, in winter it was nasty. And I had my "find-me". It was a transceiver skiers could wear, with the idea if they got trapped by a falling mountain of snow, the searchers would have a good idea of where to find the body. I'd never met anyone who had ever needed it, but my parents and I had an agreement. If I was going to be completely stupid, I had to be prepared.I'd found two of the overhangs I'd wanted, and gotten some great pictures,.
