Crystal screamed at the realization that she had been, for all intent and purposes, playing with Nathan's genitals, and she pulled her hand away quickly, as a child might do after accidentally touching a hot burner.

"Who's there?" Crystal shouted as she tried to withdraw her hand.
"It's me," Nathan replied, and then he began to laugh. "Who else would be wandering the hallway with their dingus hanging out?!?!?" Crystal stopped screaming and stammered in confusion: "Prof... Professor Davis?"
"Yes," Nathan replied. "Don't be afraid it's me."
