Before I knew it we were slow dancing in a dark corner, feeling his strong hands caressing my ass cheeks through my mini dress. He grabbed my waist fi...mly, making me rest against his crotch. I could feel a hard erection of something really huge through his pants. I was so fucking aroused when he finally asked me if I wanted to go to a bedroom upstairs. I really couldn't even believe myself when I said "yes", biting my lips and looking at him in his eyes with lust in mine.We found an empty room. Sue was playing with herself dipping her fingers deep into her vagina and then buzzing herself with a vibrator I had a throbbing erection but she had tied my hands behind my back so that I couldnt wank myself but I hoped that she would be kind to me soon. Sue withdrew her fingers, looked at them, saw that they were coated with her juices reached across and touched them to my lips for me to suck, which I did. She was surprisingly wet and kept offering me her juicy fingers and I eagerly sucked. By now, my dick was hard as rock, so she took the soap and applied on my dick and started stroking....Dammit, it felt so good. I was fondling her boobs initially while she was stroking, then I went down to her pussy to continue from were I stopped, she stopped stroking for a moment, then suddenly started stroking a little bit aggressively, like she was just possessed (I guess with the spirits of sexual orgasm). She started buckling and I knew she was close, this time I made her cum hard on my. It was thick in the legs and rungs, made to be sat on rather than looked at. It had no arms and an unusual seat which was wide at the front and very narrow at the back. The back was straight and not the most comfortable, but functional. He drew her with him to the chair and brushed the clothes which had accumulated on it away and sat down drawing her sideways to sit on his lap. Her legs draped over his left side and she was turned half way so that her forehead settled back into that soft spot.
