We positioned ourselves on s rug in front of his fireplace, on our sides a hungrily got stuck into each other. Now I'm not bad at BJs , if I do say so...myself, but James....well let's just say that I had to ask him to stop from time to time, I was soooo close to losing my nut. He seemed to enjoy me too and we stopped for a breath when he asked me to stop as he was getting close to getting off too. Then of all things, we stood and had a little cock fight. Swinging dicks, grinding and again. A second or two passed, which to me felt more like a year. Then, slowly, she kissed me back. At that point, my heartbeat was as loud as a drum in my ears, and I didn’t care that both our tongues tasted like processed chicken, I didn’t care that my erection was probably visible through my pants, and I definitely didn’t care that it was my sister that I was kissing.Now would probably be a good time to explain the family situation: our ‘parents’ couldn’t have children, so they decided to adopt.. It pulled taut and I was unable to move one way or the other.She then took a pair of cuffs she had there and cuffed my hands behind me. Now sit here she said showing me a saw horse in the middle of the barn. I moved over and straddled the legs. I noticed there was a 7=8 inch dildo attached to the horse and wondered if I would have to be on top of that soon. Within minutes I got my answer.She took some oil or lotion and applied it to the dildo and onto my ass which was now wet from sweat which. In an instant I knew that I was dripping wet, and thathis cock had to be slick with my juices. I squirmed at the raw intimacyof the feeling, and spread my legs again for him. I surprised myself morein that reaction than in the fact that I was just about to really becomea woman. The aching need inside me to be filled was stronger than thestrangeness of having a cock probing between my legs. It was simple, Ineeded this!I knew he understood that as well, and after a few wet strokes along myouter.
