Help me find this manga!

So I've been looking for this yaoi manga for ages and still couldn't find it

I read it this year but I didn't add it on my list and I forgot the title!

So basically, this is a very lewd manga. It is about two highschool boys who is already in a relationship and all they do is sex! In school, in camping, they do it! I forgot what are their features but I think one of them was blond.

Idk if the title is in english or japanese, but i think it is in japanese.
