Sybil finished cleaning me up, and she climbed off me. She eyed my hard cock with a grin, and said “So you’re ready for another? You’re ready to...give us more of this hot, tasty cum?” She didn’t wait for an answer, and she pushed me, rolling me off Marie. I lost contact with Marie’s pussy and the handcuffs key, and Sybil rolled me onto my stomach. “Get the strap.”God damn it! I was so close to getting the key. I had it there, right in my fingers. I was trying to figure out how the hell I was. After a long struggle, I, however, managed to send her to boys toilet. I told our instructor to directly ask for sex in the bathroom. She had no option other than accepting it coz grades in labs are very important to us. Secretly I left my phone in video mode in the toilet so as to record complete sex between our instructor and Saloni.Later, I went to the toilet to collect my phone. She felt so happy that she got best grades in bio and thanked me a lot that it wouldn’t be possible because of. For ages nothing happened, we joined sex sites, bought magazines and we just met brick walls or fakes. Then one day, we were invited to a gay night club in the area, for one of my friend’s birthdays. Evie dressed up as usual, in her sexiest outfit, looking fabulous. Her boobs, nearly hanging out of her top, her beautiful legs encased in lovely thigh length boots. The evening went well, the drinks flowed and we were all having a great time when Evie needed the toilet. She was gone quite some. " How was it? Sorry I couldn't make it."Oh, I think it's nice. Dinner was good. The course is not quite finished but looks nice. I scheduled it for April. Should be a good fund-raiser for us." Great! Pine Hurst was great for us. Big conference facilities. Just the right size dining room for our whole group. Hope we weren't too noisy for the other guests. And you oughta see the rooms. Plush! They offered you a free room, too, didn't they? Did you try it out?" Yes, I decided to go the whole.
