Help Please

I'm looking for one of the first yaoi I ever read. I remember that it was a collection of one shots. The first one, was about the brother trying to protect his big sister from the seme when he saw them out on a date. The brother and seme got into a fight and the police started looking for them. The both ran into an alleyway where they got into a "sticky" situation and we find out that the seme was aiming for the brother the entire time.
