Make him beg

Johnnie drives you around the neighborhood, but you pay more attention to him than what's outside the window. He really is quite good looking with a nice jawline, strong hands, and frindly eyes, and though he's a bit bumbling you find that rather endearing. From the glances he keeps shooting your way when he thinks you're not looking it's also clear the attraction is mutual.

You change your position from time to time to keep things interesting for him, and when you're going along a road without any houses nearby and little traffic you put your hand on his thigh. He jumps at first, then forces himself to relax but the occasional babbling dries up.

"You've been so kind to show me around", you say with a smile. "Is there anything I can do to thank you?" You slide your hand up to his crotch, brushing your fingers against the tent his hard-on is making in his cargo shorts. "I'm so very grateful, I'll gladly do anything you'd like. Anything."
