Sadist one. Its pretty much pure build (Karryn's desires should be minimum, especially cock desire). You need to acquire certain edicts ( you need to lower inmates chance to attack) and gear (the more, the better because of charm) to lower enemies chance to attack and acquire reality marble. (flaunt is valuable too).
Plan: 1 and 2 level-just beat up everyone, then you can start fun part.
After you get flaunt, you can start your sadistic journey:
1 turn: reality marble (cost is great, and you likely to not acquire this skill yet) and flaunt. If all goes well, inmates should be horny.
2 turn and later: keep desires low, while continue using reality marble. Use any stance skill, healing thoughts to restore energy. Inmates will jerk off, but because your desires low, they will stain the floor, instead of Karryn.
Later you will acquire skills, which will let you deny external/internal ejaculation.
