I`d love to see you naked and masturbating". "I`ll do it but you should undress, too". I ran the film back to its` start and put it on hold then we re...turned to my lounge and undressed. I`d never before seen my sister naked and I liked what I saw. So much so that my cock, which had softend a little, swelled up again. Seeing her in the flesh was much better than seeing a naked girl on my computer screen. In fact my sister was the first naked girl I`d seen. Both naked, we went back to my computer. The clothing laid out for her today was the thin sheer french maids outfit with the kitten tail ass plug, bra with the tiny pin pricks at the nipples the kitten collar with the bell and the ears. This of course meant that she had to do all of her chores on her hands and knees...and that tonight’s session would probably keep her embarrassed and aroused for days. Crawling into the bathroom every single twist sent small sharp numbing sensations into her nipples and made the small kitten like mewls. This was the rule in these circumstances. Girls in Abi’s situation could always expect several beatings during their time in the punishment room and as knickers would be speedily removed the girl was expected to leave them in her room to save time. I reached over her shoulder and undid the buttons on her blouse. She had ignored one of the rules; her breasts were encased in a white lacy bra as I known since she had first entered the room.Without a word, I grabbed her by the hair and hauled her. "The young one behind me was throbbing hard and fast. I knew he wouldn't last much longer and he started yelling, "whore" at the top of his lungs. I love good advertising."Cum in me and know you may be knocking me up!" I screamed.Reaching under me he pinched my clit and pushed one last time deep inside of me, yelled 'whore'. As Victor predicted, this pushed me over the edge. I fell on my right side and pulled my knees to my chest, screaming for more cock as Victor pulled out to his tip and came.
