Fuck yourself. You know you want to.

It's not too big, but it'll do in a pinch. With a gasp, you push your middle finger inside yourself, feeling your pussy suck it in and hold it there, tightly. You push further in, slowly, keeping your lips spread wide with the other fingers of your hand as you do. One knuckle, then two, then the whole thing disappears into your wetness, and you draw it back out so that you can start pistoning it, gripping your breast with your other hand like it's the back of your lover.
