You have another idea.

"Actually, now that you ask, I was thinking of something else."
She smiles up at you, then stands.

"Okay, sir," she begins. "Have your way."

Just what you wanted to hear. You position her on the end of your desk, turning her around and placing her hands on the wooden surface. Once she's there, you reach down and lift her skirt from the back enjoying the curves of her tight thighs and revealing a white T-bar.

"Woah," you say, "I didn't realize you wore things like this to work."

She smiles back over her shoulder. "There are a lot of things you don't realize about me," she says. "Maybe you can learn a few more of them, if you're interested in spending enough time learning..."

You smile back realizing that you'll have plenty of time to educate yourself tomorrow, and the next day, and every day you see her in the office.

You reach under her skirt, pull the T-bar down to her knees, as you kneel behind her and plant your lips on her already dampening cooch.

She gasps as your tongue separates her folds and darts inside her, exploring.

She begins to moan as you work your way to her clit, sucking it into your mouth and lapping at it with the tip of your tongue.

Once she's nice and wet -- soaked actually -- you stand up, unbutton your pants and let them fall. She backs up against you and nuzzles your bulging shorts with her ass, smiling naughtily as she grinds against you.

Why Sir, I didn't know you cared," she coos.

You grab her hips and gind back a little. "You don't know the half of it. Now get back in position." You guide her back and give her a slap on the rump. She responds with a playful shiver and arches her back in anticipation.

You carefully work your hard cock out of your briefs, dropping them as well.

Both of you properly attired, you plunge your cock into her pussy and begin to pound away at her. She moans loudly, muttering your name here and there as you fuck her. You move faster with each stroke and wonder if you'll have any energy left for your wife when you get home.

You decide that, if it comes down to it, you can always tell your wife you couldn't get away -- that the boss wouldn't give you the rest of the day.

"Oh, YEAH!" she shouts, and you begin to worry that someone might hear. She begins to moan and breath heavier, panting. You realize that she's coming and try to fuck her even deeper and harder, increasing her orgasms exponentially.

Once she finishes, she looks back at you blissfully and sighs, "Okay, you can come, but not inside me, okay?"

"No problem," you reply, already feeling it building inside you.
About thirty seconds later you pull out your cock and stroke it vigorously, launching a few quick spurts of semen on her round ass.
You catch your breath as she turns around and kisses you drunkenly.

"Got any tissues or napkins?"

"In the top drawer," you reply.

She wanders over and uses the tissues to clean herself up, then pulls her panties back up and pushes her skirt down.

"Done this before?" You ask.

She smiles and nods, "And if you're willing, I'll do it again."
With that, she saunters out.
