I quickly agreed. My wife looked over at the husband who I will call Dan and then at me saying "Are you sure, this sounds crazy?" I knew he was all fo... it by the large bulge in his swim trunks. We talked about it for awhile and decided to move it into the house where I put a porno flick on the TV. With the lights turned low, the sexual tension became so thick you could cut it with a knife. I stepped out of the room where I could still watch and Karen joined me as Dan sat by my wife. Intently. She was standing with her back to me and was still only wearing her nightie. I could actually see my cum stains on the bottom of it and I didn't know how she could miss it. But she didn't seem to notice and we had a nice cheery breakfast before she drove me off to school. My mattress was still wet the next night so I was happy to sleep with my mom again. It actually hadn't seemed to be any drier and I couldn't figure that out but I wasn't complaining. I had to keep my legs crossed or my back. Most of all, I think my sister needs a caring person in her life right now, and I don't think it really matters one way or the other if it's male or female."I laughed out loud as I asked, "So, are you going to open a kinky 'on line dating' service now or something?" I could feel the smirk still on my face.Katelyn laughed as she punched me on my chest, and then leaned over and kissed the place where she'd hit me. After the kiss, she lifted her head and looked across my chest. She leaned over and. I said “I am sorry, I did not mean to leave you alone as of a sudden, but this had to be done” he did not say anything, I wasn’t looking his direction and I felt I lost track of him, thinking he went back to the living room, as of a sudden, he was right behind me, I almost felt his breath with his head very close to mines, he held me close from the back, gluing his body to mine, I tried to get lose and get away from him, but he was much taller and stronger than me of course.He surprised me by.
