By the time you passed out, Professor Ilene got up to answer who was at the door, and got her bathrobe back on, because it was still cold outside, and left her bedroom. Professor Ilene was expecting more people to pass the exam, as she had you with her, and as she answered the door, she found both Wendy, and your roommate Tasha on the other side.
"Ah, I've been expecting you two to come," Ilene explains. "What did you need us for, Professor?" Tasha asks. "And why are you exposing your naked body to us?" Wendy agrees. "Oh, that's actually part of the exam," Ilene explains. "Now go, and get some gloves, and boots on, because you'll be joining us this evening during this exam." As the Professor returned to the room you were in, your girlfriend, and roommate got changed, and stripped naked.
