She rubbed along it for a few seconds and then pulled her hand back quickly and blinked at him.The bell rang. Lunch was over. “After school up in th... lab,” said Damon, standing and holding his tray in front of his bulging groin. “See you then.”The girls giggled and headed for their after-lunch classes. “It really is big,” whispered Vera. “Hard too.”“Mac told me he never saw a bigger one.”Damon waited for them in the chemistry lab where he had been a student assistant as a freshman. Both. I glanced up, looking across the room so that I could see her out of the corner of my eye. Seeing that she was standing side on to me and looking the other way, I relaxed and looked at her more closely.Today she was wearing a short denim skirt that hugged her hips and then flared out to about mid-thigh. Her tight-fitting white blouse showed off her curves. Thin strips of ruffle decorated the neckline and the edges of the super-short sleeves. Her long black hair was bound at the back of her neck. This was too much, I hesitated and she insisted, “ I know what guys are doing me watching me perform now I want to see it”. I knew what she meant, I’d wanked over her several times, imagining that tight young body naked.In the end my cock overruled common sense and I undid my trousers and pulled it out, semi hard but growing all the time. She seemed suitably impressed and wondering out loud if it would get bigger she pulled her T shirt off and sk** her thong off as well. That did it, my cock. Even the ones that looked like he'd been shaking too much with excitement were usable. He had been shaking so hard while shooting his naked older sister, but he wasn't too bothered about losing any shots after what had happened. Next time, he'd be more composed, he knew. He just hoped that there would be at least one more next time to match the first. He looked at the shots of his cock that Petr had taken and it finally dawned on him that, yes he did have a bigger cock than everyone he knew and.
