My favorite noncon flavors are ones where the victim is forced to be an active participant somehow. Humiliation is my big kink, so the victim being forced to put on a show for the rapist, to debase themselves in various ways, etc. is a good time for me.

I like it also when it starts with the rapist teasing and keying up the victim until they're close to orgasm (aphrodisiacs also slot in nicely here), and then break off and force the victim to get the rapist off first, and then the victim is allowed to get herself off by like, humping the rapist's leg or something equally humiliating.
