To Clean the Cum off her face.

Amy was sorely tempted to jill herself to an orgasm immediately., her pussy ached for it after her humiliation at the hands of this sexy college professor, but then she'd have had to leave here completely naked with cum all over her face. Anybody who saw her would immediately know what she'd done.

"Clo..." she started to say, but then immediately changed her mind when she remembered what she'd been wearing. They wouldn't do much to cover her up anyway and she'd still have cum all over her face. "No...I mean...I choose to clean the cum off my face." Then, on a whim she added, "sir."

Bradely smiled. He said, "Okay, go ahead."

Amy looked around for something to use, and eventually dug her clothes out of the wastepaper basket and used them to wipe her face as well as she could before, with a mild sigh of regret, throwing them away again.

When she finished, Bradley walked over to her and ran his hand up and down her body, before kissing her again and whispering in her hear, "can wait to see you next class, dress even more daring if you can."

Then he opened his door, looked out both ways, and gestured that the coast was clear. Amy, completely naked and highly aroused, made a run for it out into the hallway.
