I barely remember it.
but it was about a boy who was give a massage to the boy in front of him.even in the middle of the class since he belong to a family that give massage as a medical. somehow the boy gets the boy in front of him to go to his family clinic where he had sex,
sorry i don't remember that much.
i do remember a scene where there a loud MMM or AHHH as the boy moan by the massage in the middle of class.

gosh, I remember this but can't find it either. It's a oneshot in another manga or oneshot collection. I think he was angry that he gave him massage, because he was feeling it too much and the other one was saing he have to practice. So he goes to the clinic cause he moans in class and it's embarrassing.

Sorry I can't help. Now it's bugging me too. But it should be on my list.

EDIT: I found it (if that's what you are looking for)

the oneshot in the first volume of saa koi ni ochitamae

if there is an option between "to do" and "not to do", I will always choose the latter.
