I figured he was enjoying the show since his glance didn't falter. At any other time, my instincts would have told me to stop what I was doing.
But you know me, I'm quite the exhibitionist so I continued on, making sure to tease him.
He finally realized that I didn't mind the company at all and rolled down his window.
There was this sexy look of relief and satisfaction in his face, making me do much more.
Ever so often I'd glance back at him and blow him a kiss. The edges of his lips form a smile right away.
