HELPPPP finding a yaoi manga

Hey guys, i am looking for a yaoi manga. The uke is in highschool and is friends with this guy who has black hair and maybe glasses he likes motocycles. The black hair dude has a younger brother (donno if its step brother) but the black hair dude hated his younger brother coz he "stole" his gf by having sex with her. The uke is in love with the black hair dude and goes over to his house. There he mets the younger brother and the younger brother basically rapes the uke. The black hair dude find out and stuff happened but later the younger brother cries and apologises for what he did and that he loves the uke. The black hair dude finds out that his younger brother didnt actually steals his gf but his gf jumped on top of his younger brother wanting to have sex.

Extra chapter- the younger brother goes shopping with the uke and the uke recieves a call from someone. The younger brother gets jealous that person was special to the uke. But it turns out that ita the ukes dad and he is really young looking.

(Ps. The uke lives with his uncle and ran out from his dads)
