Ditto
it's yaoi! i can remember the top helping the bottom to prep for penetration but the thing about this story is that it showed how they used an enema, they were literally inside the bathroom and the top was helping him to use it
this is the best that i could remember. can't recall their appearances or if it's manhwa/manga.
