It was going to be a long night.I was told it was time to go and mistress handed me my purse. At the doorshe told me she had a couple of rules for me ...onight. Firstly I was notallowed to talk. I was to obey Karen as well as herself. And if I couldget through the night without messing my diapers I could take it off whenI got home and use the toilet. If not I would spend the next 3 days withno toilet privilege at all. You can think about that as you drive toKaren's. I will see you there later.. We looked at each other, and I saw her staring at my cock. she kept staring, then kinda stuttered saying sorry and ran out. I got a little turned on. I exited, and proceeded to the living room where the other 2 were sitting. I sat with them, me and my buddy on the outside with her inbetween. I nudged her, and when she looked over, I pulled my cock out. her eyes widened, and she stared again. I see my buddy peek over, and immediately decided to pull his cock out too. he was already hard, and wow. Then, looking through and not being able to see much, I gradually widened the hole on my side without affecting the pinhole on the other, until I could see perfectly! Nobody ever opened the curtain over that window, I reasoned, as there was nothing to see, and, as far as I know, no one ever noticed it.I must have spent hundreds of hours, all told, masturbating in that dark bathroom, as I watched my three sisters' young figures develop into womanhood. They were all very attractive and had nice. Well knowing both my parents would be at work I rode my bike back home I loved jerking off while wearing my mother's panties on this day I got a little more daring knowing I had 4 hours alone I stripped down went to her panty drawer and looked thru it I found a white lace teddy I got hard just looking at it thinking about how it would feel on my cock it had a high cut thong back I stepped in to it and pulled it up it felt funny with the material running thru my smooth ass crack but I liked it.
