@FreakyJester He gave consent under false pretenses, so yes it's abusive . And considering that black hair is actively sabotaging MCs career; you could consider it to be financial abuse as well.
@F.B.I. Tokyo He's under the impression that his friend wants to help him train to be an incubus; which is 100% a lie. His friend doesn't want him to pass, and is hoping that by having s**, he can manipulate him into being a stay at home husband. Most manipulative tactics have a grain of truth in them, but don't make sense if you really think about it
