Okay it was set at this elite school and the kids with the lowest grades are "toys" for the top scorers. Main kid was top scorer but grades fell and he became toy and they had so much sex that his hips became feminine and changed his body a bit and this made he girlfriend realize she was actually a bit of a sadist. I think it was mostly like humiliation or mind break kink. If anyone has any ideas, thank you!!
