The bus leaves the car rental station headed to the airport.  You sit across from me and I notice your hand move to your crotch under your short skirt.  We lock eyes; I can tell you’re rubbing your pussy.  You smile at me and open your legs wider.  I see you’re making your thong wet. 

Looking back into your eyes, I watch you progress from playing, to gasping, to moaning.  Then I see you shudder and quake as your orgasm washes over you.  I lock eyes with you as you come down. You leave and I pocket the wet thong.
