Anyone?

So uhm im looking for this manga where the uke is a univ student, then he always lend his apartment to his friend to use when friend and his gf want to fuck. Then he has a neighbor that uhm idk i forgot but seme (neighbor) knows that the uke liked his friend (the one w/ gf). Then they become fubu coz the uke is pent up and seme helped him. And uhm at the end, the friend and gf knew that the uke is gay bcos they listen to them when seme and uke is doing it. Im sorry if its confusing, idk how to storytell XD
