Better yet imagine if you pull up to the next station, and just as the doors open the place packed with people he starts moaning at the top of his lungs, and dumps a huge load inside you as they all stare in disgust😜
I would say as far as that goes it's the giving of dick vs the taking of dick that would define gayness, fucking a guy in the ass is gay, but far gayer is letting a man put his dick in your ass,
