Get her off with your tongue.

You bring your face close to her pussy, spreading her with your fingers, plunging your tongue into her as far as it will reach. She growls, pressing her ass back against you. You give the inside of her cunt a few long, deep licks, then move your attention down to her clit, and you hear a brief frantic cry that Rebecca manages to stifle before it can become a full-out shout.

The next long, lovely minutes are a haze of sensation: the taste of her pussy, the feel of her wet thighs against your cheeks, the sounds of her arousal: ?Oooh, yes. Oh, baby, yes. God ... ohhhh, yes.?

Eventually, she loses the ability to form words; her only sounds are grunts and gasps and groans. You sense that her desire is building to something, so you press your mouth firmly to her, licking her clit lightly but rapidly. She reacts to your change in pace by pushing her hips back against you. ?That?s right, just like that, oh yes, yes yes, yes, OHhhh....?

She stifles another shout, and turns it into a series of deep, **** gasps as she rocks her hips back against you. You slow down a little, trying to soothe with your tongue instead of provoke. One of her gasps turns into a long, low, moan as the tension leaves her body, and her hips sway lazily, smearing even more of her dripping wetness over your face and chin.

?On Monday,? she says, ?you can come crawl under my desk. I?ll wear a skirt.?
