Terran Cummando: A Gay Science Fiction Novel

When fledgling commando Lou Angelino is transfered to the starship Vindication, he doesn't realize he is about to be made a sex slave to the entire crew. From the text: "Our friendship grew during the first weeks. Brad had been the last new guy into the squad, so we tended to stick together. One night, about two weeks after transferring in, I awoke in the middle of the night, an unusual occurrence for me. It took me a few seconds to realize what had aroused me. At first it was a slight movement, and I realized that Brad was shaking the bunks. I was then fully aware that he was jerking off! I lay quietly and listened to the slight movements and his breathing. When his breath caught in his throat, I knew that he had just cum, and I was even more aroused. What did his member look like? I wondered. Brad rolled over and I listened as his breathing indicated he was asleep. My own arousal needed to be dealt with, and I slipped my boxer shorts down below my balls, and very carefully began to rub and stroke myself to orgasm. It was difficult to be quiet, but I managed to keep my groans down as I shot all over my tummy. It was more powerful than usual, which confused me."
