It's killing me, i need to know what this is called!!

okay guys, there was this one yoai, i believe it was the uke who basically thought boss? i think it was, was attractive but that didn't stop him from flirting/sleeping other guys. i hardly remember how it went but i do remember one scene, the uke is making out with some guy in the bathroom stalls and he's like " your such a good kissing " or sum like that. but when he try's to go further he find that he has a small pp so he leaves and on his way out he bumps into his boss. that's the last scene i remember if anyone knows what this yaoi is pleassee tell me i need to know, please and thank you.
