Masturbating With Another Boy Under the School Desk

The first time I touched another guys cock was at school when I was 15. For a few lessons a week we went into a classroom that had double desks and I had to share one with a boy called Jamie. He had the reputation of being one for the girls and certainly he was popular with them. I had never had much to do with him as he wasn't in my circle of friends. The double desk we shared was a bit isolated from the rest of the class by a large built-in cupboard. I wasn't too keen on sharing the desk with him as I'd rather be near my own friends but I had no choice and it was only a few times a week. During one boring lesson I suddenly noticed that he had his hand nearest to me in his pocket and it seemed to be moving rhythmically. At first I though I was mistaken until I looked down again out of the corner of my eye and realised that the hand was making definite movements. I kept looking without letting him know and after a while I saw his body tense and then shake a little and his breathing became ragged. I knew without any doubt that he'd been rubbing himself off and had just had an orgasm! The next time we sat together I watched to see if he'd do it again and sure enough he did. This time I nudged him and indicated that I knew what he was doing. To my surprise he just grinned at me and grabbed his bulging trousers with his free hand so I could see the outline of his hard cock. Then he took the hand nearest to me out of his pocket and to my surprise grabbed my hand and pushed it into the pocket. I soon realised that the bottom of the pocket was cut away and my hand went directly onto his hard cock. It felt so hot. He whispered "Go on, wank me but keep it in my underwear". I slowly rubbed him but he wouldn't let me take it out and insisted that it stayed inside his boxers. Nobody could see what we were doing because of the position of the desk but we had to be careful and pretend to be taking notes and listening to the teacher droning on. He got me to unzip my flies and slid his hand inside and then pulled my cock out. I was quite nervous even though it was under the desk and nobody could see. We wanked one another for a while and he whispered that he was about to cum. I made sure his cock was covered inside his boxers and felt it jerk and heard his sharp intake of breath as his juice spurted out. His cock jerked in my hand and he gasped very quietly and his whole body shook and his face was flushed. Even before he'd finished I whispered that I was cumming and I shot my load onto the classroom floor, later to be rubbed in by my shoe. Luckily he was careful not to get any cream on my school trousers. I pulled my hand out of his trousers and put my cock back and we acted as if nothing unusual had happened. After that experience, most times when we sat together we played with one anothers cocks not always to orgasm but if it was safe to do so we repeated the first experience. Strangely I never did see his cock as he refused to take it out of his trousers even though he always got mine out. At the end of the term we stopped using that classroom and he started going around with a steady girl so those hot sessions ceased. We barely acknowledged one another as we had different sets of friends. But it was very exciting though in retrospect quite stupid as we might have been so easily caught.
