It's incredibly annoying me cause I remember the manga pretty well, but I can't remember the title and I also can't FIND it somehow.

The title has a guy with short hair lick his lips while showing off his muscular naked breasts. He is either a ginger or brown-haired, if I recall correctly.

The story itself is essentially that there's a club where customers can come to play with men's breasts aka groping and sucking. There were three couples over the course of the story, if I recall correctly:

A young-looking guy (let's call him A) that falls in love with a dude that only sat by the bar and drank instead of actually being a proper guest while that guys friend is getting "introduced to the club's offerings". Both of them had some sort of issue (impotence? I honestly forgot) and they work it out together as they begin to secretly date.

The "slut" of the club who was blonde, I believe. Always horny and incredibly into the entire club thing, too much even as he has to get reminded that its not allowed to have anything but the breast touched or smth. He ends up dating the security guy who always points out that he is straight; they at one point fuck on a couch.

The buff guy from the cover (he's B). He and A are childhood friends and he is a virgin, yet acts experienced. He keeps taking the unruly customers such as the friend of the guy who A ends up dating as well as a Yakuza dude as he feels protective of the other club workers. B has been in love with the club's owner who is also somewhat his adoptive father due to having been saved by him from his mother. The love goes nowhere cause not only is that guy straight, but also marries during the story and his wife ends up pregnant.
His story is the main arc of the manga. He ends up together with an architect that is equally as buff and moves into a community home with the guy, kinda. There is a scene where the club organizes an "audition" for who should date B. At some point A and B fight which leads to the club owner finding out that B is in love with him.

The manga ends with a new club being opened thats essentially just a cafe, so those that aren't actually really into the sexual part can just have a nice chill job while still being together.

Like.....I recall it quite well, but I can't frigging find it.
