So, this is an idea I totally just got off one of my favorite hentai's: Saimin Seishidou
This is the story about how a school counselor held an assembly where he mind controlled all the students to thinking that if they were going to pursue any form of intimate relationship, then they would need to talk to the school's counselor about sexual conduct.
What the students don't realize is they are being raped and fucked senseless while their boyfriend watches thinking that it's what they should be doing all along. Feel free to have your character be anyone from the school and we can craft their "lover", however you want.
I'd like my character to be in his late 20's. Let me know if this interests you.
