Cheerleader rape and ballbust reverse idea

[Justinian]

This is in a sci fi setting where science is a little more advanced that it is in real life. This is necessary for the role play to work. Anyway, there's a hopeless nerd who's also a jerk who gets seduced by a group of cheerleaders. He's thinking he's hit the jackpot, but the girls are really going to show him who's the boss. I'm looking for ballbusters. . .

What could turn me on is them all making fun of his "size', girth and performance while they are doing the deed.

He would repeatedly undergo extreme pain in his balls. . while recovering from it every time through the medical technology of the day.
