Have to get inside her.

She lets you shove your pants and shorts down to your ankles before she straddles you again. She braces one hand on your desk and reaches down between her thighs with the other hand as she starts to lower herself. You guide your cock into her hand, and she carefully positions it where she wants it. You feel the wetness of her pussy, and then pressure as she starts to sit down.

You can tell immediately that you?re not quite at the right angle, or your cock isn?t slippery enough, or both. The head of your shaft enters her, and then stops. ?Hang on,? she says, shifting her hips slightly. After a little more tantalizing wiggling, she takes her hand away from you and sits all the way down, her pussy gripping you tightly as it slides down your cock. You and Rebecca both groan in unison.

She?s leaning forward against your desk, knees spread wide, panting as if she?s just taken a run around the building. You are equally breathless, holding her bare hips, marveling at the way her cunt twitches and throbs around your cock. Once she has collected herself a little, she tenses her legs, drawing herself up a little so that she can sit back down again, and then again, and then again. Wet, warm pressure massages your cock, sending waves of pleasure and need through your body.

You rock in your chair, bringing your hips to meet her whenever she comes down on you. ?Uhh!? she cries, the first time you thrust against her, and then, ?Oh! ... yeah ... yes ... yes ... ohh ...?

You know that you?re ahead of her, but you can?t slow down. You feel your cock starting to swell, and so does she. Her gasps start to get wilder, and her motions get faster. She bobs up and down on you, smacking her ass against your thighs, driving you up inside her. You hang onto her hips, pull her toward you, thrust and thrust - and explode.

She draws a sharp, high-pitched breath as you slam into her, filling her with surge after surge of wet, **** orgasm. You swallow a shout, turning it instead into a long teeth-clenched groan. While you you buck against her hips, she hangs on tightly to your desk, riding out the **** of your climax.

When you start to slow down, she makes a hungry, needy sound, takes one hand off your desk and plunges it between her thighs. From the sounds and sensations that follow, it?s clear that she?s fiddling rapidly with her clit, propelling herself toward her own explosion. ?Ahhhh ...? she moans, ?ohhhh nnnnngggg godddd ...?

Her head tosses. Her body trembles, setting off a cascade of stimulation in your still-tender cock. You bite your lip to keep from yelling, and hold onto her hips. Her fingers flicker and flutter. Then her chin jerks up, and she is silent for a long, trembling moment as her hand blurs between her legs, and then at last, she lets out a loud, ecstatic, victorious gasp.

You gasp right along with her when her cunt takes firm hold of you, squeezing you as she orgasms. Both of her hands are back on the desk now, and she shoves her hips down against you, forcing you into her as deeply as she can. She throws out her chest, sucking in air, moaning and quaking in your lap.

Her head droops when she finally comes to rest atop you, panting softly. You feel as if the building might have exploded under you, tossing you into orbit, where you remain, drifting and spinning. You feel as if you might stay this way for days, but she interrupts your mutual bliss by saying, ?We either need to figure out how to wheel this chair back to my bedroom, or you need to help me stand up.?
