LOOKING FOR YAOI MANGA!!!!

So like i've read it b4 but i can't remember what its called, this is what its about(as far as i remember): This salaryman?(small, cute, Uke) is on the train, and the only other dude is this good looking guy(Tall, muscular?, Seme) and the Seme is watching porn(He doesn't get turned on), but he forgot to put his headphones in properly so the Uke can hear everything, and he recognises the porn actor(chihiro i think, its a female) and i'm pretty sure Seme and porn actor have same name. And the Uke gets turned on by her voice, so he gets a boner, but Seme sees that and yeah one thing leads to another and Seme kinda forces Uke to have sex with him, numerous times.
Thanks a heaples guys!!!!!!!(づ￣ ³￣)づ
