I wasn't proud of that. But the truth was, it turned me on even more. On some level, I felt like I would be just as disgusting and fucked-up a person ...if I sat there and jerked off while watching my mother get tag-teamed by the twins as I would be if I went upstairs and joined in. But of course that was crazy. However weird it was to be turned on by watching it, and it was weird, there was no way that compared to participating. It wasn't guilt then that made me decide to stay at my desk, even. Nothing!On a hunch I go around the house to the back door. There, the door is open and the screen door is closed. I linger for a moment as there is a small clothes line off to one side and what to my wondering eyes should appear, but several panties hung to dry!Yummy, silky ones of different pastel colors. Lacy ones and even one thong! I tear my eyes away from the silky scene and find that she is standing in the doorway smiling! I try to recover and we go right for the areas that need. She was leggy, so feminine with wide hips and so much face surgery she didn't even look Thai... She wasn't the trophy ladyboy. By no means unattractive or manly but just not the pick of the bunchShe acted so innocently flirtatious and I could see she was a complete sissy, like putty in my hands and for the first time in my life I was gonna show a side to me that I'm still not sure now is good or bad,,,We walked in the room, she giggled and asked what we should do. I walked towards her slowly. He smacked me hard on the assand I jumped. He rubbed his hands across my ass. "Tell me you wantit," he said. I was hesitant and shaking as I did as I was told,"Please, fuck me baby." With that he pulled my panties aside, there itis again "MY" panties, and slowly slid his hard manhood into me. Icould feel it penetrating deep inside me. At first it hurt, but as hegot going..it felt so good. It felt amazing. I got lost in it. Iwanted it deep in me. I could feel my body wrapped around.
