You've received a message on your phone. A professor from college has invited you to an orgy! The message reads:

"Greetings, user!

The college is organizing an activity to encourage students to get to know each other better! All sorts of different experiences will be available at this event. Please confirm your interest and availability by responding to this message" The message contains the time and location for the event. At the location, you are greeted by Prof. Tanaka, who's wearing a thong and pasties. She greets you, takes your hand and leads you inside. You are immediately inundated with the smells of sex and sweat, as well as the sounds of moans and gasps.

"Welcome!" she says with a grin. "Glad you could join us. To begin, I'll need you to remove your clothes." As you do, she looks you over appreciatively. "So, what are you interested in trying out? Or perhaps I can show you around, introduce you to some of the others?"
