I would say good kill even if he was running out of the house guaranteed he will not come back and whether he was invited or not does not matter She is under an age to make that decision and he’s of age to know better I read a few cases where men had sex with underage girls even though they consented and they still went to jail
“and whether he was invited or not does not matter She is under an age to make that decision”
That may depend upon facts not stated in the question. For example, if a minor invites someone into the minors home, the person invited could be considered an invitee, authorized to be there. On the other hand, if the parent asks a person to leave and they refuse, the police could be called for help removing the trespasser
