Touch her.

Once again, you reach a finger down between her thighs, and trace the line of her pussy up to the cleft of her buttocks. She shivers this time, and you do it again, downward this time, exploring her warmth. You stroke, and tease a little, and when you start to hear little noises of desire from under the desk, you slip a finger into her wetness, finding her clit.

This time she gives a short, sharp moan, and she pushes her hips back toward you. You take this for the encouragement that it is, and start to play with her clit, stroking slowly up, down, and around. ?Ohhhh,? she groans, ?I swear I?m going to make sure your computer breaks every day.?

She?s thoroughly wet now, and you take the opportunity to slip your finger back to her cunt, and then inside. You slide your index finger into her a bit at a time, and she draws a long, shuddering breath. You start to give her long, deliberate strokes. Her hips move in time with your thrusts, pushing toward you, urging you deeper.

?I don?t suppose you could do that for the next six to eight hours,? she says.
