You do

She surrenders entirely to your hungry, cold lips as they devour hers, moaning weakly into your mouth as your tongues meet inside. Your hand slips underneath her dress, your sharp nails making her shiver as they trail up her delicate thigh, before cupping a generous ass cheek.

You lean into her, your great bare breasts against hers, nipples hardening against the taut fabric of her dress as your kiss becomes deeper, hungrier, wetter...your lips smack as Natasha's shallow breathing quickens, your spit running down her chin.

She surprises you with her hands on your breasts, thumbs flicking your eager nipples as your cold flesh warms at her gentle groping, eliciting ripples of pleasure. You reward her initiative with a kiss on the length of her skinny throat, hearing her mewl as you sucked on the perfect skin, fangs brushing against it as you nibbled.

She twiched and withered as you teased her neck, gasping and purring while her head lay to one side, eyes closed, smiling dreamily. It was returning now...her sweet taste arousing your hunger, the loud thump of pumping veins in your ears once more. You give her long neck one last sensual lick, before opening your mouth wide, your fangs still bloody with your last meal...

Suddenly you hear the screech of brakes, and the two of you are thrown against the back of the driver's seat, before bouncing back. Natasha yelps at the shock but is fine, still held in your arms. Your face is covered by your own disheveled hair, but it does little to mask your furious expression.

You rise and give the idiot driver, likely distracted by your's and Natasha's foreplay judging by his erection, a stern slap across his head, enough to make him cry out in pain. "Eyes on the road, or I'll tear them from their sockets and hang them from the rear view mirror!" You snarl. You wouldn't, of course...far too messy. Better to just snap his neck.

He nods, too terrified to reply. You turn back to Natasha, who eyes you expectantly, her lipstick smudged. You consider carrying on, but in truth, the interruption was a blessing in disguise. As difficult as it will be to explain your nudity to any curious parties, a young girl dripping with her own blood would be far worse.

As much as it pains you, you sit back and restrain yourself to simply resting Natasha's head on your shoulder and caressing her hair. She seems as disappointed you at first, but enjoys the affectionate embrace, perhaps the first in a long while.
