Everything was fine until it was time for me to leave. With a three-hour drive ahead of me and work the next morning, I started to realize the reality... ahead of me. As we kissed goodbye she placed her hand on the device, claiming it as her property. She then placed a sealed envelope in my pocket asking me not to read it until I was home. As soon as I walked through the doors, I had a raging urge to pee. Then it sunk in. Sitting to pee, every time. I managed and after I cleaned myself up I called. As I re-applied my make up using a small mirror, Patty pulled from her purse a short squat rubber device shaped somewhat like a cock, cut in half and rounded smooth. "Kythe the real reason that I brought you back here was to give you this, from Marilyn." While Patty was moving to bend me over to insert the dildo in my ass, she was explaining that "This is a special training dildo, which you will wear for the entire evening, except when your ass is otherwise disposed." "There is a small. I would love to give myself to you but I’m not sure if I can really offer you what you want since I don’t have a pussy.” “The way I see it,” I told him as I slipped my fingers back inside his ass, “you do have one that I’d very much love to be inside.” He smiled with relief and longing and soon was on his knees in front of me asking me to be gentle. I didn’t have any condoms but decided it was safe since he was a virgin. I lathered a lot of lube on my cock and his ass and he teasingly squeezed. It was hard though, because my brother Andy shared a room with me. We were twins and so my parents didn't think we really needed our own rooms because we were so close growing up. Except now we were teenage boys who wanted to masturbate as much as possible. I'd usually wait a while until I thought he was asleep then I'd go to work on myself. A few times though I'd stay up and before I started I'd here the shuffle of sheets on the bed across from me and I could tell he was masturbating. I didn't.
