Give her a choice (+cool +submissive): 10+, she’ll clean up the professor

“...would love to clean up your cock.” she slides to her knees and wraps her lips around your shaft again. She licks up and down your length, relishing the taste of her own pussy.

“Thank you for letting me suck your beautiful cock, professor. You taste so good!”

“That’s you tasting good Eliza. You’re cleaning your juices off my cock.”
