John awoke with a start, the wall slowly coming into focus as his eyes adjusted to having newly been opened. As had been happening all of the past week, he had an erection, thanks to his dream. This dream was different however, as this time he dreamt of when Henry fucked him yesterday, instead of the first time.
Yesterday had been substantially more pleasurable than the first time. It didn't hurt as much, he wasn't as scared as he knew what to expect, he was ravenously horny, and Henry hadn't worn a condom, so John had experienced the full bliss of skin on skin contact.
He looked over his shoulder to make sure Henry was still asleep so he could masturbate, and was surprised to see him standing right next to John's bed, completely naked, and fully erect.
John rolled over fully and sat up in shock, but Henry didn't move an inch. He just stood there in silence, his cock occasionally bouncing as it throbbed. The movement caught John's eyes, and he stared at it, knowing exactly how good it felt to have it inside him. He tried to look away, to not give in to Henry, but he couldn't.
Henry finally spoke. "You want it don't you? You can't even take your eyes off it. Admit it and it's yours. Ask me, and I'll fuck you better than I have before. You'd be on your knees begging for it if you knew how good it'll be." He leaned forward, until he was a few inches from John's face. "But you don't get it until you ask. I got other people I can fuck, so it doesn't bother me. You're the only one missing out here." He stood back up and stared at John, waiting for an answer.
John was still yet to tear his gaze away from the bouncing cock. He knew Henry was waiting for his answer, but he said nothing. He could no longer deny it to himself; he wanted it. He wanted Henry to bend him over and fuck him like he had before. He wanted to know how much better it could possibly be. But all the arousal in the world couldn't make him admit it out loud. After a painful internal struggle, he managed to shake his head no.
Henry smirked. "Fair enough. But you seemed to have trouble, so I'll ask again tomorrow." He went back to his bed and put his clothes back on, just in time for the morning alarm to go off and the cell door to open. "I'll see you later", Henry said casually, then walked out the door.

John lay awake at night, waiting until he could hear Henry's snoring. He'd been desperate to masturbate all day. He couldn't understand why he was so turned on by all this. He was completely ashamed of himself at how much he enjoyed being this man's sex toy, but the shame and humiliation only seemed to turn him on even more. What made it worse was that Henry seemed to enjoy having this sexual power over him.
It was the next night, and Henry had asked again that morning. John had managed to say no again, but Henry's arrogant smirking as well as flexing his hard-on while standing right in front of John had almost caused John to give in and admit that he wanted it.
He listened out for Henry's breathing, but it sounded like he was still awake, and John was getting tired, so he gave up waiting, and went to sleep.

The next morning, Henry didn't try to make John ask him, but he was awake first, meaning John didn't get to masturbate again, leaving John to spend the whole day on edge, just like yesterday and the day before.
The only time he saw him that day was at lunch, when he was sitting a few tables away. Henry spent the entire time just staring at John with that cocky smirk that made him feel small, helpless, used, and desperately horny.
It wasn't until that night that he saw Henry again. John was sitting on his bed reading when Henry came in just before curfew, and without saying a word, he disrobed, and stood before John completely naked, and harder than steel.
John dropped his book in surprise, and gasped when he saw Henry's cock. As per usual, his eyes were instantly glued to it. Henry knew he had John right where he wanted him, so he began to flex his cock. Holding the flex for a few seconds, then letting it go. Repeating the process again and again, while John looked on helplessly, almost becoming hypnotised.
Try as he might, he was unable to look away. Even if he were gay, he wouldn't have thought it would be considered an attractive penis, but he knew the ability the owner of it had, and what he could do with it. His own dick grew until it matched the hardness. He sat there, watching it slowly rise and fall from being flexed, until Henry spoke.
