[Locked] Looking for a hentai i read long ago

Im trying to find one i read a long time ago, have been looking for it from time to time as i remember it to be pretty good.
So the MC is in highschool and ends up in the nurses office for some reason, he has sex with her (if i remember right) but another teacher barges in and she hides him under a cover, the nurse ends up tricking this other teacher into having sex with him while he is under the cover with the reason being its a "toy" or something.

Thats basically what i can remember of it, if anyone has any knowledge please help :D
