I see.If you want to you can still offer "corruption-style content" in this setting. No coercion or stupid mindbreak rape but the PC can guide the women towards more extreme, kinky or otherwise initially refused sex acts. Only instead of the usual "a good slave knows how to take a gangbang" you might have a girl with intimacy issues working the gloryhole, so you gradually (and with informed consent) teach her how to deepthroat and perform rimjobs, then PiV/anal at the gloryhole and maybe she gets used to it and eventually takes clients face to face. Getting the aunt to sleep with the PC would also require corruption of at least one of them (she can be the initiator!) unless they're both in the Alabama mindset to begin with.
I don't know what fractions of corruption fans seek which aspects, honestly most of the games with that tag aren't even remotely close to working on real humans and some are just outright rape. By definition "corruption" involves shifting someone's morality to a less socially accepted view without forcing them but in some of the discussion threads the reason people enjoy the games is phrased more as "a desire to destroy something beautiful" which rape does satisfy while consensual morality shifts mostly don't.
I always thought that corruption was a woman going over her own moral values because of some blackmail or outside influence that she couldn't deny, so she ends up giving in.
Perhaps the term has a broader meaning than that.
