I was seduced by my cabin mate when I was a 16 year old cadet at sea, or possibly I seduced him I do not know. Ship was trading in the tropics in the far east, very hot, no aircon in those days. Off duty we would sit around in just underpants or with a towel wrapped round. to keep cool We chatted read books or magazines listened to the radio. I was I believe what would be called a pretty boy, fair hair, blue eyes and a hairless body, my mate was a couple of years older. Sometimes that chat would be about sex, on the first occasion when anything of a sexual nature occurred, My cabin mate saw because i was only wearing underpants that my dick had become stiff and he remarked on it and told me to stand up so he could see better, I refused and tried to hide my erection. After tha it became a bit of a game with him trying to make me hard. he discovered that if he started hard at my crotch I would get stiff. If I needed to get something I had to stand up and what was inside my pants or towel was very apparent, It it became a bit of a game with us both. One time, I was wearing a towel and he asked me to stand up , I did and he pulled the towel off , so there i was with cock pointing at the deckhead stark naked. Nothing really happened for a while. One night my mate had turned in, he had the lower bunk. I got up to turn in and put off the cabin light then went to get into my upper bunk. To do that I had to put a foot on the edge of his bunk to climb up. A hand shot out grabbed me round the waist and hauled me into his bunk in a semi crouched sitting position. It was not a good position to struggle in and he was bigger and stronger than I was. He tod me to masturbate him, I refused. He shoved his hand down inside my pants and played with my cock wich despite my best efforts became hard and then excited and then I shot my load. he laughed and again told me to jerk him off but I refused again, so he resumed fiddling with my dick which had only partially shrunk and he soon had it hard again and after a while he made me cum again. The he told me to go and wash up my pnats were soaking. so I dumped them washed and turned in. In the morning , naked and with the usual morning erection of the teenager I just got out of my bunk and washed at the cabin basin with the erection in full view. After that as you can imagine I was his bitch, but no sodomy and I refused to fellate him. We would jerk each other off. Sometimes he made me stand naked in the middle of the cabin and masturbate in front of him.
