I'm looking for the name of this hentai manga:
The guy cums insane amounts.
Both his teacher and school nurse have sex with him.
One of the girls in his class is a futa.
Later there's a school inspector that is supposed to find out what's going on and ends up having sex with them.
I remember some extra manga at the end where the guy is having alot of anal sex with other students and a comment about it being good against constipation.

Would be glad if someone knew what the name of the manga is 😛
