To my pleasant surprise she was wearing a thong made of some sort of metallic looking fabric reflected all the colors of the rainbow. I sat here trans...fixed staring at her panties. The way the small scrap of cloth covered her and concealed her. The way it cupped her sex, the way her pubic hair made a soft mound under the iridescent cloth... My breathing was getting a little heavier now. I let her skirt fall back on to her stomach giving me a hands free view of her panties.I had the sudden urge. "Have you ever played with bondage?" she asked."Yes," he said."As dom or sub?" There was a twinkle in her eye."Dom usually. Sub occasionally." Mike's always been the dom, but tonight I am tying him to a chair. Come with me," she said.Bill followed her down the hall to the master bedroom where Mike stood at attention by a large and imposing straight chair. He was naked except for briefs and leather restraints buckled around his ankles and wrists. Short chains dangled from the D-rings on the. Hearing Nick say these words and watch Mike the clerk check out at my body again was crazy exciting. Mike didn’t at first believe what he was hearing, but when I assured him that I had lost the bet so if he wanted me to, I would show him my boobs. "OK… I’ll call your bluff, show me your tits. It's been a real slow night and I’ve been bored to death so a little excitement might be fun.” I then experienced wild erotic excitement like I had never felt before. I was so scared, but I slowly. I stood straight up and retreated to the edge of the pool to sit on the deck. As Kelly was approaching, I adjusted my trunks leg to make sure there would be no restrictions on my dick, and that it could be seen by looking up my trunks leg from where Kelly would be positioned. She got in front of me and hopped on my foot without the usual chit chat, but I didn’t mind. And was hard. She started rubbing as before and I immediately picked up her cadence. I couldn’t tell if her bikini material.
