To a Friend

As you leave your apartment carrying black haired Rose on your shoulder, she continues pleading with you.

"Please, John! I'll fuck you, and do anything you want me to. Just don't **** me to be a carpet muncher."

"Rose, I'll fuck you if that's what you want. But you're also going to fuck a friend of mine."

"That's fine. I don't mind fucking two dudes."

"That's interesting to know, Rose. But this friend is a chick. She's going to help me teach you the joys of sapphic love."

Who is your friend? Another teacher? A student?
