Most of the time our office Christmas parties are a drag.

On the rare occasion when they have turned out to be fun, you may look back and wonder why you did what you did.

This last one was one of those you’d wonder about. Gina has worked in our office for two or three years and seemed kind of quiet and reserved, maybe because she wasn’t the slimmest girl in town. Since the staff dresses mostly in scrubs, no one had noticed that over time Gina had transformed herself into a hot piece of work.

For the event she had poured herself into a very revealing dress, showing just what workouts and healthy eating can do. She’d always had a cute face with a great smile, and piled-up long hair that she let down that night. But the shocker was the deep cleavage-revealing V in the front of her dress. The snug dress flared just slightly to show off her shapely ass and long legs atop sling-back “fuck me” high heels. Usually she came to these parties conservatively dressed and with her dorky boyfriend in tow, but not this night. He’d been called out of town on business, or so Gina said.

The evening started out slowly, but things heated up. Gina, usually a sideliner, was attracting quite a bit of attention — but it seemed she was only interested in me, even though she was dancing with every guy who asked her. A couple of the girls got a little pissed because they thought Gina was flirting with their dates, something she never would have done in the past. Meantime, I couldn’t take my eyes off her. Between numbers, we moved toward each other, and she was the first to speak, saying that she had worked very hard to get in shape and hoped that I’d noticed the improvements. Not to worry. I’d noticed her as much as she now noticed the bulge in my pants.

She and I danced a few dances, and we got more than a few glances when I cupped her ass and pulled her toward me, grinding my cock into her crotch. I reached under her dress, only to find just a stringy thong. It was pretty apparent that we were already the talk of the party, so I suggested that at the next break I take her home. Out in the air I took her car keys and headed with her for her car.

She reached down to unzip my fly as I drove. As soon as my rod was free, she went down on it, deep-throating as much as she could. She kept at it, licking and sucking and driving me to distraction. When we reached her house it was dark, with only the garage-door light to illuminate the way in. Gina led me upstairs to the bedroom, which must have been her plan all along.

She took off her dress, sank back on the bed, spread her legs wide, and told me to take her any way I wanted. Glad to oblige, I mounted her pussy and began thrusting in and out, hard and fast. With all the moaning and yelling, I was oblivious to the bedroom door opening. Moments later I discovered our visitor was her naked boyfriend; not the best specimen of manhood. A little taken aback, I slowed down until I heard him whisper to Gina that now she could get some of the fucking she’d only dreamed of.

Sensing that I was part of the plan, I went back to pounding her now soaking cunt, while the boyfriend began fucking first her mouth, then her tits.

We switched positions, with my rod now fucking her melonlike creamy tits while the boyfriend made the best of her wet pussy. I was so busy after that, working up to getting a great blowjob, that I didn’t even notice when he raised her legs over his shoulder to ream her tight ass.

Between moans, Gina begged for us to spew our loads in her mouth so she could taste the sperm of two men at once. We waited until just the right moment to pull out and aim our dicks at her open lips, jetting out the jizz simultaneously. She had her tongue out, a great target. Some of the spunk made it into her mouth, some all around her lips, and the rest streamed down her chin. Drenched and satisfied, we all fell asleep until morning.

I can only hope that the rest of the staff was too wasted at the party to remember our blatant mating ritual on the dance floor.
