Let her be.

You decide against stripping her -come morning, she might not appreciate what you've done for her when she wakes up naked in a strangers bed. No, it's better to leave her dressed. You can offer her a shower and some of your own clothes when the morning comes.

Leaving her be, you slouch off to the living room and stretch out on the couch. There isn't a ton of room to sleep, but at least it's plush, so it will have to do. You aren't exactly all that tired, though; and more to the point, still feeling more than a little randy from the experience of having her in your car, her hand on your crotch. Normally, there's a pretty simple and easy solution to that problem, but now that you aren't alone in the apartment, are you certain you want to fire up the computer and treat yourself to some late night porn?
