No one. She makes it back without being disturbed

When Tanya gets back to the gym, the teacher is waiting for her.

"Close your eyes and don't speak unless told to do so." he says. The second after she does this, she feels someone come up behind her. One of their hands grabs her left tit, the other begins stroking her pussy.

"Do not cum unless I say so." she hears, as the stroking becomes more intense. She feels his boner press up against her ass, and it begins rubbing against her crack. She involuntarily moans. The stroking and rubbing go faster and faster.

"Beg me to fuck you." After processing this, she begs like a bitch. She whispers, "Please just stick it inside me. Please. I will do anything, just do it."
