Replying to Is this wrong?

okay so today in school during end of the day Home Room my friend jacked off to our math teacher(shes pretty hot) while she was in the room like 20 feet away. he then proceded to wipe his jizz on my friend right next to him. She then called him up becasue he was laughing so he does the 12 o clock tuck or the school boy tuck while she was talking to him she kept looking down at his pants like she knew what he just did. I think its pretty perverted what do u guys think?
