Please help me fine this yaoi manga title

Hi, I once read a yaoi manga a few years ago that I really wanna re read, but I can’t remember the name. I clearly remember a 18+ scene that could maybe help in the search. It was a couple having sex on a bed while the home owner goes into the room and kisses the bottom as “tax” or something like that. And if I remember correctly the home owner had long hair, not sure tho. Please if anyone can help me find the title I’d really appreciate it.
