Im not sure if youre into noncon but are there any that would override mc's wishes, or brainwash/hypnotise them in to "consenting"?
There's definitely a few monsters who could be driven to it, but one of them that wholeheartedly takes part in it would be Aris, the tiefling puppeteer. Hypnotism is an art he's become hellbent on perfecting, and although it has its uses to make sure you don't go anywhere or leave his side for good, he also likes it when you fight him just as much as when you obey ♡
(cws: noncon, hypnosis)
Sure, at times he wants a relaxing evening with his beloved where you won't struggle or bite him or kick him away when he wants to make love, and that's when he puts you under hypnosis--but most times he likes it when he has to force you. Sometimes you need correcting, and sometimes he just needs a warm hole to sink into after a couple glasses of wine. He usually tries not to be too violent, but he might land a hefty slap across your cheek if you're getting too riled up for his mood to handle, and that usually can stun you for long enough for him to slip it in. If you just won't let him get his dick anywhere near you, then he's been known to use his tail instead if you're gonna be that much of a prude, and half the time watching the tip catch as he thrusts it in is more than enough to sate the bloodlust that flickers behind his eyes. That, and the way your body slowly goes limp in fear as you realize there's no other choice but to give in to what he wants.
Aris would also have no issue with forcing one of his puppets to accost you, including Z--the reanimation spell he used to bring him back from the dead also has its uses for putting him under hypnosis, and if it's necessary to put you in your place, he wouldn't mind watching voyeuristically as the zombie mindlessly wrestles you down to pin you under his weight. The best part is that it doesn't matter if you kick one of his legs loose or smack a few fingers off his hand, he won't stop growling and chasing your squirming heat until he manages to sink into it, all under Aris' command. He won't even remember it when he wakes up--and Aris can use him again, and again, and again to chase you down and make you give up what you should know belongs completely to him.
