Slide over and give them a show

Seeing Alexis's tight g-stringed ass spilling out from under her skirt as she jiggled her massive fake tits at the car next to you sends you over the edge with the desire to fuck her now instead of waiting for her to pull over. You suddenly stand up, grabbing alexis by her waist while shaking her to add some extra jiggle to her tits and lift her up over your lap as you sit down in the driver's seat. You pull her down on your lap, grinding her ass up and down your bulge eliciting a "oh" from alexis interrupting her chuckling at the car of onlookers as you place your left hand on the front of her panties and the other on her ass. Alexis leans back against you, placing her head next to yours and moans "fuck me". You slide your pants down, pressing your cock against her g-string as you move it out of the way ready to show the car full of losers how to fuck.
