Play it safe and quickly get yourself off.

You know the difference between being a perv and a ****, and while you'd love to have your cock as deeply buried inside her as your finger currently is, you know there are limits.

Pushing another finger up into her intimate warmth, you begin to finger fuck her in long slow strokes, you thumb lightly rubbing over the hood of her clit. You stroke your own cock with the same deliberate pace, curious to see how long you can draw this out, and if you can make her all wet and loose inside before you give in to your inevitable climax.

Indeed, it isn't very long before you can feel her moisture on your fingers, and the way her breathing intensifies gives evidence of the effect you are having. You lean closer, eyes flitting from her vacant face to her pussy and your buried fingers, hand working your erection with increasing urgency. You're so close to can practically kiss her, and can smell the whiskey wafting from her breath. At the same time, you can detect the musk of her excited sex beginning to fill the interior of the car, and small wet sounds now accompany the movement of your digits within her.

Your own arousal has overtaken hers, however, and as your balls go tight and the pre-cum coats the surface of your reddened glans, you can feel the moment of no return is at hand. Teeth gritting and body tight, there is nothing you can do but remain in that awkward pose, holding your breath as the first wave of orgasm hits you. The first jet of warm semen lands directly on her naked thigh, and you are powerless to restrain yourself as each successive pulse smears itself on her skin and track pants, trickling wetly onto the car seat.

Even after your orgasm has passed, you remain in that pose, half elated and half horrified at what you've done. Removing your fingers from her cunt, you swallow hard, thankful that she hasn't woken up from your selfish adventure. The last drops of your emission are draining from your softening cock, coating your hand just as it now coat's Miki's lap and leg. Dazed but recovering, you quickly put yourself right -well, as best you can anyway. Biting your lip, you have to decide what to do about Miki. You're going to have to wake her up to get her inside her home, but how exactly do you want to play this off? Trust that she won't notice what you've done to her, or try to explain yourself as best you can?
