anyone?

I read this manga a years ago, before I made an account in here. soI cant marked it. the plot is about a uke *actually seme* who working at i dont know if it's a gay bar, or something like prostitution office. the seme met the uke in there, actuallly that's the first time the seme come to place like that, and then the uke seducing the seme, and they have sex, actually the uke who actually a seme's want to teach the seme about sex between guys, but it ended with he is being the uke for him. I'm sorry, I kinda forget about the story.
I hope there's somebody who know about that kind of story.
thanks a bunch. arigatou :3
