I was working late a few weeks ago and figured I was alone in the office.

It was well past eight o’clock when I decided to take a break and have dinner, so I grabbed the leftover salad I’d saved from lunch, bought a soda from the vending machine, and went into the conference room to eat because there’s a TV in there.

I’d just sat down and was about to turn on the TV when I noticed some lights on in the office across the way. I had no idea what the people in the building next to ours did, but I knew that the office opposite mine always emptied out by 6 p.m., so I was surprised to see the lights on. I walked over to the window to see if anyone was in there, and at first glance, it seemed like the office was empty. Then I turned my head to the right and saw two people standing next to the copier. I thought nothing of it and started to eat, turning the television on to catch the news.

I finished my salad in maybe ten minutes, and since there was nothing good happening in the world, I clicked the TV off and went back to my office to finish my project. My window just so happens to be across from the other office’s copy machine, and when I walked in my door, I was looking directly at the people I’d spotted earlier. Only this time, they weren’t just standing next to the machine. Now, they were caught in an intense lip-lock.

I felt a little pervy watching them, but I couldn’t help myself. The few times I’d seen anyone in that office, they’d appeared pretty buttoned-up, and they certainly didn’t seem like the type to get up to after-hours shenanigans, so I was intrigued by this turn of events. And, okay, I’ll admit it, I was turned-on. I’d been working late so much that I’d been neglecting my own love life, so seeing a couple getting hot and heavy was more action than I’d had in a while.

When their make-out session went from PG-13 to NC-17, I decided I’d worked enough. I turned my full attention to the couple across the way. Sometime when I’d been collating my own copies, he’d stripped her out of her clothes, and now when I looked back, she was on her knees, sucking his cock. I couldn’t see much detail from where I was, but I could tell that he had a nice-size shaft, and I was impressed by the way she was able to deep-throat him. I didn’t hesitate to slide my hand into my pants to rub my pussy. Like I said, all those late nights had me in a bit of a rut, and I was desperately horny. As I watched, she sucked him with all she had, and I stroked my pussy in time with her movements. It was hot!

My eyes were still glued to the action when she pulled away and he dropped to the floor with her. I was glad they had full-length windows and that my office was a few feet higher, because it gave me a great view. As soon as he hit the floor, he shed what was left of his clothing and climbed on top of her. I watched as he rubbed her pussy a bit to spread around her moisture, then thrust his fingers inside to make sure she was ready before sliding his cock into her.

As he pushed his dick between her pussy lips, I impaled myself on my fingers and pressed my thumb over my clit. Then, once he started moving, I matched him stroke for stroke. Each time he swiveled his hips, I made sure to twist my fingers inside my pussy, and when he started jackhammering into her, I pushed down my pants enough to give me room to do the same with my hand. I shoved a third and then a fourth finger into my cunt, wanting to feel as full as I was sure he was making her feel.

She was bucking up against him and squeezing his ass, and I could just tell that she was a good lay. I couldn’t decide which of them I wanted to fuck more, so instead I imagined myself in a threesome with them.

As I watched, he flipped her over onto her hands and knees and thrust into her again from behind. Now she was able to play with her pussy while he fucked her, and though I couldn’t see how her hand was moving, I imagined that she was moving in sync with me, and it pushed me even closer to my climax.

I was so aroused from the sexy show in front of me that I came suddenly, almost surprised by my own orgasm. The couple across the way was still going at it.

I watched them for as long as I could, but eventually I went to the bathroom to wash up and splash some cool water on my face. When I returned, they were gone, and I had no choice but to get back to work.

Even though I stayed late every night for the next two weeks, I never saw the couple again. But now, when I’m alone in the office late at night, I have some nice fantasies to keep me from getting bored.
