Looking for bl manga (posting again)

Looking for bl manga. It's about the seme calling call girls to his apartment but instead of using his own room he has been using his roommate's room. The uke (roommate) gets pissed at this and offers the seme a toy (a cup of some kind to help him get off). The seme refuses and then the uke insists on using his hands/mouth to help him get off. The thing about the uke is that he is a germaphobe and one day when the seme and uke were out w friends he accidentally mistook the seme’s drink for his and he didn't have a disgusted reaction. Then later the uke started to develop feelings for the seme and the seme found out about this and after the whole incident w the call girls he started to mess w the uke. I hope this is enough info. Thanks in advance!!
