Put your hand between her legs.

You reach one hand around her and find her strong, smooth thigh, then slide your fingers back up toward her body. She purrs, takes her hands off your keyboard, and leans back into you. Your touch find the inside of her thigh, close to her crotch and her skimpy shorts, and she falls silent. She continues to make no sound when you reach even further inward, drawing a fingertip over the narrow strip fabric between her legs, but she spreads her legs wider and holds your arms with hers, hanging on tightly to you.

You stroke her through her shorts while she shifts on your lap, trying to find the position that gives you the best access. ?Okay, these are coming off,? she says at last, and she stands free of you long enough to unfasten her shorts, shove them down to her ankles, and kick them away. You have enough time to note that she?s not wearing underwear before she sits back down in your lap, puts one of your hands around her waist, and puts the other back down between her legs.

She?s very wet, and your fingers slip very easily into the contours of skin between her thighs. She gives a long moan that she draws out as your fingers find the bump of her clit. She is squirming against you, dripping wetness onto your pants, rubbing her ass over the increasingly eager bulge of your cock.
