" Don't be disgusting - you find your own place away from mine." Mum replied."Please." I begged, "I've never seen a woman peeing and I thought after l...st night that you wouldn't mind. Please." I told you that there was going to be no more of that and I meant it!" she said."I don't see why not - I promised you that I wouldn't tell anyone and we didn't hurt anybody. Please let me watch," I entreated. I could see her wavering"Please let me' I continued."I think it absolutely disgusting" she said,. Ireally do. Now, sweetie, just sit tight and I'll be back."With that, she arose and went into her bedroom. I shifted,trying not to make any noise, lest I arouse her ire. I took afew breaths through my nose and tried, like I often do in crisessituations, to piece together the events of the last half our.Nicole, my best friend's girlfriend, a sweetheart from PuertoRico, who had been so supportive and so excited about my cross-dressing and with whom I had never exchanged an ill word hadgone crazy.. It was just Lyn and I.I knew what would happen because this orgasm was bigger and better than our last one and I had passed our then so…….. I could feel her contractions trying to pull sperm out of my empty balls and my cock was trying to help. When I started to feel pain I knew that I would black out soon and I did.My mind was telling me that nothing could ever be better than this. I was with the most beautiful woman in the world. She had the the most beautiful body and the most beautiful. She couldn’t have sex with her stepbrother, but maybe she could do something... ?Thinking that part of the problem was that she could see Cam’s face, she turned the side table lamp off and, careful of her sprained ankle, she pushed Cam onto his back and straddled his hips, facing him. She was being so naughty! She settled the crotch of her panties onto the underside of his cock shaft so that she could feel her pussy lips parting slightly around it through the fabric. Then she started to move.
