Why not? She's asking for it

You grab her hips, pushing her back against your car, your hands running over her body. She moans, writhing against you, hooking one heel behind your knee. You tug her dress up, pushing her onto the hood of your car, one hand squeezing her breasts, the other probing her pussy. You're not surprised to find her drenched and ready. You unzip yourself and free your stiff cock, pressing between her thighs.

"Oh! Oh! Not on the car! People might come!"

"People are going to come. I'm going to come," you tell her, rubbing your cock up her wet slit, easing it in to her velvet folds. She rocks her hips against you, still protesting weakly about fucking in public, but not hesitating to cling to you, one of her slim fingered hands guiding your cock into her. You hold her tight round ass and drive yourself home, pounding her against the hood of the car, fucking her hard and greedily. She's fucking back just as hard, the frustration of the last few days finally finding release.

"I want you so much, I want your cock so much," she groans into your mouth, her legs wrapped tightly around you. "I've wanted this so long, so long, you don't know how much I wanted you."

You're getting close, holding her ass and thrusting deep into her tight wetness, uncaring of her needs but only your own hunger. The excitement of the semi-public fuck adds to your urgency, and hers to judge from her gasping eagerness. With a long groan you start to come, spurting into her, your throbbing cock pulsing with orgasm. She bites your shoulder, stifling a scream, and lets her own spasms surge through her, her shudders shaking her tiny body.

"So Good, so good, so good," she murmurs, her writhing gradually slowing. You pull out of her, and tuck your slowly softening cock away. Looking at her tousled and disheveled, sitting with her thighs open on the hood of your car, your cream starting to dribble from her pussy, you say the first thing that comes into your mind.

"So do you still need a ride, or will that one be good enough for you?"
