Don't care and instead turn the nerdette over for one more banging

"What? Didn't you... oomph!"

You silence the nerdette by smothering her mouth with yours. The excitement of not knowing where you are heading makes you stiff as a pole again, and as luck would have it, a bump in the road helps you spear the nerdette to the hilt in one great thrust. She promptly forgets all about her speech.

As she raises her hips to meet your thrusts, you scrape your belly over her clit, and soon she digs her fingers once more into your back as she explodes again into orgasm. Sweat drips from your nose into her eye and you see stars and cum and cum and cum.

As you come to, you hear noise outside the car. City noise. And you're slowing to a stop.

"For heavens sake, don't just keep fucking me! Do something!" you hear the whimpering nerdette say.
