John's eyes slowly opened. He had been dreaming. Like every night for the past week, it was the same dream - the recollection of when Henry took his anal virginity. And just like every other night, he was sporting an erection so hard it was almost painful. And also just like every other night, the first thing he did was to make sure Henry was still asleep, then masturbate, thinking of his dream.
The first 2 mornings he had cried afterwards at the shame of what he was doing, and while there were no more tears, the shame was still there. He couldn't help it though. There was nothing that turned him on more than the memory of how good it felt to have another man's penis inside him. How amazing it felt to have his prostate stimulated. How intense it was to cum purely from being fucked in the arse. Recalling the memories made him cum with 30 seconds of starting to masturbate. He caught it in his hand and quietly got out of bed to throw it down the sink in the corner of the cell.
Sitting down on the toilet to recover, he put his head in his hands, disgusted with himself once again. It had been 5 days since, and Henry hadn't made the slightest recognition that it had even happened. He said that it would happen again, because he knew John liked it, but it hadn't. John didn't know how he felt about that. On one hand, he didn't want it to happen again as he wasn't gay, and being the bottom for another man was humiliating, but on the other hand, he was already starting to feel himself grow hard again at thinking about it. He certainly wasn't going to let Henry do it without a condom, as he had recommended. He shook the thought out of his head, and tried to keep it out. Henry was starting to wake up, which meant it would be time for whatever work they were assigned that day.

Staring at the ceiling, John waited until sleep came. Despite working hard all day, he wasn't very tired. A noise made him look up, and the source made him sit up in shock. It was Henry, completely naked.
"Come on, pants off. You know what time it is."
John sat in silence, his mouth moving but no words coming out. He had been completely by surprise, and didn't know how to react. His body apparently did, as within seconds he was completely hard. Hoping the thin blanket covered this, as he didn't want Henry to see his arousal, he stammered. "Uh, you...what? I don't-"
Henry held up a hand and John fell silent. "Stop talking, take your pants off, and turn around." There was no aggression, no violence or anger in his voice. It was completely calm. It wasn't so much a demand as it was an instruction on what to do next.
