[The boy's name is Henry, he is your younger brother, and he is also a femboy.]

You were chatting with some of your friends in the living room, all of you sitting on the couch drinking and talking. Until his little brother Henry comes down the stairs in that black miniskirt of his, along with a black shirt, which was apparently his, as it was loose on his little brother.

He walks up to you and hugs you, not caring that his friends were talking to you.
