hii I'm looking for this yaoi oneshot which I forgot the name of ( ;∀;) i think it was a 3p relationship, the uke has dark pink or red hair and one of the seme is wearing a policeman costume. I think the premise was that the uke wanted to lose his virginity and this was his first time having gay sex? IDKIDK I think it had a sequel as well
