I am looking for a yaoi manga that I forgot the name to... Basically a straight salaryman meets a gay guy at a bar and the gay guy promises the man that he can please him in bed. Curious and doubtful, the salaryman takes him up on his offer and they go to a love motel or back to his place. The gay guy then tries to please him and is very excited that he was able to give the salaryman an erection after the salaryman belittles him and tells him that there is no way he is attracted to him. The gay guy is also an uke. Please help me find this manga! Thanks
