Tease her

Knowing that she's trying to hide the fact that you're under the table, and the fact that her massive cock would be visible to anyone looking under the table, you realize that you can't help yourself.

Moving to your knees, you lightly touch your tongue to her balls, which immediately causes her to jerk. "Oh, fuck!" you hear as she shudders violently.

"What was that?" her friends ask.

"I just meant, oh, fuck, I can't believe that happened!"

You see her subtly scoot closer under the table. Does that mean she wants you to keep going?
