Name of manga

I don't remember much but I remember the following scene:
The uke is slutty or heartbroken and he tries to hook up with a guy at the back of an alley. But the guy has brought one of his friends who wants to join in but the uke doesn't want to and they force him and hit him. Then either the seme caughts them and helps the uke or the uke goes to the seme's house covered in bruises and he's like "I didn't think there would be two of them". Do you know this?
