My ears twitched in frustration as I gazed at the computer screen.  It was already past nine o’clock.  I had stayed several hours late at work every day this week in an attempt to finish the big project we’d been working on for months.  Unfortunately, as I reviewed what I had accomplished so far, it looked like I had at least one more week of late nights ahead of me.  Even worse, I was pretty sure that I would have to work at least another hour tonight to stay on schedule.  I decided that I needed a break if I was going to keep working, so I got up from my desk to take a quick walk.

As I strolled through the cubicle farm, I assumed I was the only one left in the office.  I allowed my mind to wander as I walked.  All I could think about was how much I wanted to go home and relax.  Work had been pretty stressful lately, and I hadn’t had much opportunity to unwind.  On top of that, I was dealing with some serious sexual frustration.  No recent girlfriends, no recent bar flings, no time to masturbate – between all of that, I felt kind of pent up.  As a result, many of my thoughts of “relaxation” involved vague sexual imagery.

I was shocked back to reality when I turned a corner and ran into one of my coworkers.  I turned towards the other person to apologize.

"I'm sorry –" I stopped as I realized who I had bumped into.  "Holly?"  For a brief moment, my indistinct thoughts became very specific as I imagined throwing Holly onto my bed and humping her wildly.  I suppressed the mental image immediately.  Why did I have to run into her when I was feeling like this?  Holly was extremely attractive.  She was a fox, like me, but not just any fox.  She was easily the sexiest vixen I had ever met.  Embarrassingly, she featured prominently in more than a few of my night time fantasies.  Somehow I had never worked up the nerve to ask her out, even though I normally didn’t have trouble with that sort of thing.

"Clay!  Sorry I ran into you, I wasn’t watching where I was going."

"It’s fine; I wasn’t paying attention either.  I thought I was the only one still here."  I helped her pick up some papers she had dropped.  "I can't wait to finally finish this project."

"I know what you mean."  She paused in thought for a moment.  "Hey, if you have time, would you mind coming to my cubicle?  I want to ask you a few questions."  It may have been my imagination, but she seemed to be holding back a grin as she said that.

"Sure, I can help you."

I followed Holly to her cube, trying not to get too distracted by her swaying hips and fluffy tail.  We had worked together closely over the course of this project.  It was normal for one of us to show up at the other's desk with a list of questions.  Once we were both inside her work area, she turned to face me.  Something seemed off.  The look on her face reminded me of a predator toying with her prey before the final kill.  The next words out of her mouth made me feel like a teenage boy who had been caught with a stash of dirty magazines.

"Clay, do you find me attractive?"

"W-what?"

"Don’t pretend you didn't hear me.  Don't act like I've never caught you looking at me, either."

"Holly, I can explain..."  No I couldn't.  I had no idea what to say.  I searched her expression to try to guess if she was angry, or if she was going to lecture me about sexual harassment.  She cut me off by laughing.

"No need to be so nervous!  I'm just teasing.  Lucky for you, I find it kind of flattering.  Besides, you're pretty good looking yourself."  She gave me a cute little wink that caught me off guard.

"You think I'm good looking?"

"Yep.  Now how about you answer my question?"

"Um...well...yes.  I find you very attractive."  I felt my confidence returning as I got that secret off my chest.

"I'm glad to hear it.  Now that that's out of the way, there was something else I wanted to talk to you about."  She moved a little closer to me.  "I've been under a lot of stress lately, and I was wondering if you could help me deal with it."

I grinned at her.  "I've been under a lot of stress myself.  I'd be happy to help.  Do you have anything in mind?"

"Well, I did hear something interesting today."  She edged even closer until we were nearly touching.  "Apparently sex is one of the best stress relievers."

"That is interesting."  My inner voice of reason popped up to warn me that this was stupid.  Trying to live out a porn scenario in real life was a terrible idea.  I took that voice and stuffed it in a box in the deepest part of my mind.  "I'm willing to give it a try if you are."

As soon as I said that, she leaned forward and kissed me hard.  I kissed her back.  Our tongues explored each other's mouths, and our hands roamed over each other's backs.  All too soon, she broke away from our embrace.  She turned around and bent over her desk.  Her tail brushed against my chest, and then she raised her firm ass in the air.

"Well, Clay, what are you waiting for?" Holly asked as she turned her head to look back at me with a sultry leer.  I couldn't believe this was happening.  It was as if my dirtiest dreams were coming to life.  This sexy vixen was presenting herself to me, offering me a quick casual fling with no obligations.  As she flagged her tail, I knew I had to take advantage of her offer.

I flipped up her skirt to expose her white cotton panties.  With one hand I caressed her ass; with the other I reached around to finger her pussy.  She seemed to be getting wet as quickly as I was getting hard.  Her appreciative moans made me bolder.  I grabbed her underwear and pulled it down to her ankles.  From a crouching position, I lifted my muzzle to delve into her pussy with my tongue.  I explored deep into her folds, then retreated to lick across the outside of her slit and twirl the tip of my tongue around her clitoris.  Her delicious primal musk overwhelmed my nose, making me painfully aroused.  I soon grew too impatient to continue the oral ministrations.  Instead, I stood up, unzipped my pants, and parted the fly on my boxers.  My rock hard fox cock was finally free to do what it wanted.

I grabbed her hips and penetrated her vagina with a single hard thrust.  She gasped loudly.  I continued to ram my penis in and out of her in long strokes.  Her moans and gasps were music to my ears, but I figured I'd better make sure I wasn't hurting her.  "I'm not being too rough, am I, Holly?"

"No, this is great!  Keep going!"  To prove her point, she started pushing her hips back against me to meet every forward thrust.

After a few minutes, I decided to make our position a little more intimate.  I leaned forward until my chest was against her back.  My head was now next to hers, so I could give her little kisses and licks along her neck and muzzle.  I even threw in a few nibbles on her ear.  At the same time, I wrapped my arms around her and began fondling her breasts.

"Do you like this?" I asked her.

"Yes!  Oh, Clay, it feels so good!"

I smiled.  It was good for my ego to know I was giving her that much pleasure.  We soon fell into a steady rhythm.  In many ways, we gave in to pure instinct.  We stopped speaking; communicating only through feral moans and growls.  I began to imagine that we weren't in a cubicle, but out in the wild.  I was an alpha male taking his bitch.  I felt my climax slowly building, and I decided to assert my dominant position.

"I'm going to knot you," I growled at her.  She let out a high pitched whine that signaled her submission.  I started thrusting even deeper.  My swelling knot popped in and out of her hole several times before locking in place.  Once we were tied, I rutted her with short, fast thrusts.  By this point, she was panting heavily, with her tongue lolling out of her mouth.  I grasped the scruff of her neck in a mating bite and gave another deep growl as I came, releasing thick spurts of semen deep inside her.  My thrusts continued even after I finished.  A certain sense of pride made me determined to have her reach her own orgasm.  Luckily, it didn't take too long for her to catch up.  She howled as she finally climaxed, and her inner muscles clenched around my length to try to milk a few more drops.

We slumped together against the desk, breathing heavily, as we came down from our sexual high.  Once we caught our breath, I pulled her up and we shuffled over to her desk chair.  It was a bit difficult, but we managed to sit down.  I wrapped my arms around her stomach as we waited for my knot to shrink.  We didn't say anything; we only enjoyed the afterglow.  After a few minutes, the rational part of my mind started to recover, and I realized that I had to break the blissful silence to ask an important question.

"Holly, what kind of birth control do you use?"

"I'm not on birth control."

"What?"

"Don’t worry; I'm not in heat, so we'll probably be fine."

"Yeah, but there's still a chance..." I trailed off, not knowing how to respond to this development.

My knot finally receded, so we stood up and started cleaning the mess we had made in the cubicle.  I glanced at her face several times to try to judge her expression.  The fact that we had just had unprotected sex didn't seem to bother her.  I tried to calm myself with the thought that she knew much more about her body than I did, but I couldn’t shake a vague feeling of apprehension that had come over me.  Once we had removed the evidence of our tryst, we both decided it was time to start the weekend.  She gathered her things, and I returned to my cubicle in a daze to get my stuff.  We met again at the elevator.  I asked her if she wanted me to walk her to her car.  She responded that she would like that.  Our trip across the parking lot was silent until we reached her car.

She smiled at me as she said goodbye.  I tried to return the gesture, although my expression probably came out a bit lopsided.  I headed to my car as she drove off.  I had been looking forward to a peaceful weekend, but now I wasn't so sure I would be able to relax.  As I drove home, I contemplated what would happen if our little affair produced a child.  My mind ran through endless lists of questions.  Would we try to raise the kid together?  Would Holly want me to stay out of it?  Would we live together?  Would one of us stop working?  I knew at the very least that I would have to start setting aside some money to cover the possibility of child support.  I groaned as I realized that our "stress relief" session had caused me even more stress.
