I lowered my mouth and softly licked both her nipples. I started on the left and licked the right one. She told me that if felt nice and asked if we...could continue practicing. I went back to the left one and I started licking and sucking on it, taking her whole tit into my mouth. I heard a soft moan coming from her. I continued, sucking harder and harder, switching from one to the other, knowing how much she was enjoying herself. After a while, I stopped and I told her that I bet she. The slave straightened a little, pulling the skirt up over her knees, feeling the soft rubber between her thumb and forefinger, the texture of the "fuck me" hose against her palms. Her hips began to sway back and forth, like she was imitating a snake, as she tugged and pulled the tight, rubber miniskirt up her legs, first one side, then the other. When the waistband was finally in place, over her hips, she gave a little grunt, and thrust her hips forward, totally unaware of what she was. “I don't know...”I can't say the idea didn't intrigue me. Not so much for the chance of sex or whatever, but if anything, a chance to finally see those humongous boobs out in the open—just to put an end to their mystique.“Well, it's not a terrible idea... And it's not like we're going to fuck...” she said more to herself than anything while contemplating. “Completely naked?”“Don't ask me,” I shrugged. She most definitely was serious, and I began to question whether or not I actually wanted to. There stood another twenty something year old guy. He walked in and asked '...everything ready..." The mail boy looked at me and said "...think we are crazy now..." The Mail boy started to undress as did his friend, once they were out of their clothes they both started to stroke their cocks. The Mail boy said to me "...think about it, tonight it's just the three of us. to morrow every one in the building will know your secrete..." defeated I asked "...How do I know you still want tell..." They.
