The next day when she came in from work, she had a bundle of clothes for me. They were obviously used and clean, and not a bad fit although a little o...d fashioned. She mentioned taking me to where I wanted to go on the Wednesday evening. I was disappointed to hear that, as I’d come to enjoy her hospitality very much. That evening I excused myself to go to bed early, and thought about what I could do to get her to change her mind. One thing I thought was obvious, she was a lesbian and I was. My heart was racing with anticipation about going in there. What would i be able to bring myself to do? I put my dollar in and noticed the size of the hole in the wall. It wasn't long before a beautiful looking cock came through that hole. God, i was so turned on. I grabbed it and started stroking it while stroking myself. I felt so hot and thought i was going to shoot my load immediately. I had waited so long for this moment and fuck, i was hard. The mystery cock got harder as i stroked it. I. I mean real fucking. Cmon, sis, how bout it? We both need to know how to do it and we can teach each other. I know a website called XNXX where we can learn a bunch, too. Cmon, lets do it. Cassidy stared at the first grown cock shed ever seen. Every time she blinked, it seemed as if it grew longer and fatter. In addition, she discovered her hand was on her own mound, her fingers seeking her slit, through the fabric of her underwear. But, Billy, youre my brother. I dont think brothers are. By now, my cock was rock hard and nuzzled up against her soft, virgin pussy. She rolled over to face me and put her arms around my neck. Looking at me, she said, "Donny, I love you so much. I want to be with you forever.". I smiled and said, "Ging, your my sister and you always will be. And someday, you will find someone you will fall in love with and want to be with forever.". She looked into my eyes and softly said, "I've already found someone. You!" And as she kissed me, I couldn't help.
