When I was a young cadet I shared a cabin with the senior cadet, that was the normal arrangement. I was 16, he was 18, a big lad and strong. I was I believe what was called a pretty boy , fair hair, blue eyes , hairless body, it caused quite a few lewd remarks on board which was embarrassing. The ship was trading in the far east, hot and tropical. In the evening we would retire to the cabin and chat, smoke, play cards or listen to radio. No air con in those days cabin stifling hot, stripped down to under pants usually for coolness. Sometimes my senior would stare at my pants and foolishly I said one time do not do that it makes me hard. Well naturally he did and it became a bit of a game him staring and me curling up to conceal what was happening. One night things went further. It was time to turn in he got into his bunk, the bottom one, and I got up from the cabin settee to turn of the light. My dick was hard and quite obviously so in just my pants. I tirned of the light and went to get up to my bunk, that involved turning my back on the bunks and putting my foot on the edge of the lower bunk to climb up to mine. I had shot out and I was dragged backwards into the lower bunk bit folded because of the top bunk above and fairly helpless I did try to struggle up and out but he was much stronger an it was an awkward position. He slid his hand under the waistband of my pants, I was still hard and grabbed my cock. He fiddled with it for a bit and of course it got harder, my struggles were useless. After a short while I felt the surge of feeling and I knew what was going to happen, the sperm pumped out and he laughed. Now he said you are going to wank me, I said no. All the time he was still holding my cock and he started to tease it again well it got hard again and after a while the feelings rose and I had a second orgasm, he laughed and said ok you can go and clean up now. My pants were covered with cum. I got up took my pants off and dumped them in my laundry drawer and washed myself at the cabin basin and climbed into bed, naked. In the morning I had the usual boys morning erection and I was nude, I had to get climbing down from the top bunk, my senior could see my state of arousal, he laughed and said I think it needs some more of my attention, I washed and dressed, my mind was in a whirl about what had happened to me. All day it was in my head, I had basically been raped, the thing making me ashamed was that he has made me cum and when you cum you like it. That night we sat about talking as usual, I kept my shorts on over my pants and got into my bunk first. He put the lights out then climbed up into my top bunk and said ok now you are going to pull mine, I did. I was demoralised and that was the pattern for the next few months until I paid off in Singapore. to join another ship
