I received a response so quickly to my last post, I thought I'd try again!

Uke has to work hard to keep scholarship, and seme suggests cheating, which uke actually does. Seme blackmails uke with this info to have sex, but uke starts going to seme's tutoring sessions. Tutor turns out to be seme's cousin. Hope that was descriptive enough for someone to remember!

Thanks in advance if anyone can help me!

PS-I read through other's posts to see if I recognize any plots, but everyone else who replies must have better memories than I!

Sounds like Hidoku Shinaide.

Yes, it is! Thanks so much!
