Jay was both excited and furious. There was no question about it... Sean had pinned Jay down, and taken control, and that was unacceptable. Sean had to be taken down a peg.
Jay got the Chronovac and programmed it, this time so Sean would notice his changes, and accept them without questioning too much. And the changes were set to happen the next time they had sex. Next time, Sean wouldn't do any pinning down... his muscles would get smaller, and his frame would get more girly. In fact, Jay decided to have a little more fun with him, and when these new changes kicked in, Sean would also have a strong desire to please Jay and think of Jay as his boyfriend, and himself as Jay's girlfriend, even though his body was male, outside of having a pussy. Jay decided that Sean would act more like a girl too, but not like a gay guy acting like a girl. It would be natural. And Sean's hear would rapidly grow out long and pretty too when this all took effect.
Sean would be aware of all of these changes, but would be so horny to please his boyfriend, that he would only question for so long before giving up and enjoying being submissive to Jay.
"There, that fixes that," Jay said, pushing the button to make the changes happen next time they had sex. "Nobody dominates me."
Jay left the room and rejoined Sean. Too bad he was so engaged in conversation with Sean, or he would have noticed he hadn't been alone in his bedroom.
