A bully

Apparently, the girl was not here on her own will.
The guy who was opening her bra right now was a stupidly grinning boy, half a head taller than me.
"Now, let's see them titties" he said.
"Please, no Masao," the girl cried.
"I want to see your tits!" the boy said clearly louder.
The little girl did not move.
"Geez - Do I have to do everything myself here?" With these words, Masao tore girl's blouse open. Two buttons ripped off and flew across the room.
Neither of them seemed to notice me.
