The room was sparsely decorated; an impressionistic painting of a man and woman on one wall; a chair, a small table. “Some party” I said to myself...I sat on the chair and looked at the envelope the bouncer gave me. “Read me immediately!” it said so I opened and read it.“Welcome. You are about to get into an exclusive sex party. At this point, you have a choice. If you do not wish to participate, knock thrice on the door through which you entered. If you wish to proceed, undress completely and. Anything!"--- I met with Allan and explained how the boys blackmailed his wife with pictures they'd sneaked of her sunbathing nude in her back yard. I made no mention of Anna's hunger for Monster's cock and her willing, even eager, meetings with him that compromised her in the first place. I explained how they'd forced her into playing sexual games with them, showing herself naked, playing tie-up games, even more pornographic pictures, and the like. Then, as their nerve grew, their demands. I heard them both utter an audible sigh as they sat down and I filled the glasses. They almost immediately drained the first glass before relaxing a bit as I refilled them. I could tell they had been putting in a solid days work, they were both sweating and had scattered dirt smudges, but for some unknown reason I found my attraction for Shelly growing again. She was wearing a summer weight maternity top and I could clearly see her bra through the thin material. Her tits filled the cups fully. "So you mean to tell me that if we hadn't agreed to the bet that you would have been naked anyway?" That's correct," I said laughing. "But I think that the outcome for me and Loesje is much better this way."Both boys laughed and then Jan said, "Shit, I had heard something about a girl going naked to that party this evening, but I never thought it was you. You sure make us look like fools!" You two are no fools, just two guys who know how to have fun." I said smiling. "Well, we'd better walk.
