You lick up the cum as she gets off her face.

"So…" You say with some pride in your voice, "How did I do?"

"Well….I say." Barbara cringes a little bit, "A C….+"

"A C+!" You yell, "But…but I made you cum!"

"Well…I cum a lot, and it didn't help you needed guidance, most people can get me off sooner then you did."

You slump your shoulders, Barbara puts her hands on your shoulders, "Aww…don't feel bad sweetie. It's a matter of life. Men don't know how to eat pussy as women can. But don't worry."

Barbara smiles, "You have plenty of time for improvement with the next workout regiment that I have in mind."
