I was sitting at my desk and my cock was throbbing for the naked pussy of my wife’s best friend. She was laying just a few strides away from me, on the couch which she’d slept on, in the room adjacent to my office.

I was looking down at my cock which was poking out from underneath the waistband of my pajamas, when I heard a soft knock at the door. In my desperation not to be discovered in such an aroused state, I jumped up and opened the smallest crack in the door. It was her.

"I just wanted to thank you for having me last night before I take off" she whispered through the crack in the door.

Based on her softly spoken words, and my assumption she had agreed to a muted goodbye, I was taken aback when she pushed open the door. She stood at the threshold. We were now face-to-face, and I was hoping we could conclude our goodbyes without her seeing what I had going on down below.

She opened her arms and leant into a hug. As we hugged, I could feel my semi-erect penis press against her waist. This was bad enough, but the warmth of her body and the softness of her breasts hardened me even more. She stepped back with her mouth open, then slowly closed her lips to present a smirk. All I could say verbally was sorry, but the redness in my face spoke volumes.

"Wow!" she said, and then asked if she could let me in on a secret.

Apparently, my wife had shared private pics in the past and this wasn’t the first time she had seen my erect cock—albeit in my current state, it remained hidden underneath cotton.

"Take it out!" she demanded.

At this point you’re probably wondering what went through my head, wondering how I dealt with a million thoughts all at once, but surprisingly, when I think back, I didn’t hesitate for a second and simply pulled down my pants to reveal my thick, burgeoning cock. It was so easy to comply.

Our lips met as she leaned into me, and we began to kiss. As we did so, I slowly traced my fingertips up the back of her inner thigh to her ass cheeks, then used my finger to trace the crack downwards to her anus. I lingered there as our kisses got deeper and sloppier, then delved just a little further and gasped as my fingertips glided into her pussy with ease - she was already dripping wet. I suspected that she had as much of a restless night's sleep as I had, and that perhaps she had been aroused for god knows how many hours too.

Her breaths got deeper as I worked 2 and then 3 fingers inside her. She had a delicious cunt which felt even better than it looked. She grabbed my arm and asked me to fuck her. She looked at me wide-eyed and told me how she wanted to feel my thick cock rammed into her gaping hole. As I positioned her over my desk, I pulled her t-shirt up, and it was evident her pussy really was gaping.

Her legs were tan and her vulva presented a smooth mid-brown framing to her open and shockingly pink labia. The entrance to her cunt was a deeper pink, which glistened with her juices. As visuals go, it would be difficult to imagine a more sexually intoxicating view. It seemed like all my senses were stimulated to the extreme, as my cock squelched into her from the rear. She gasped and placed the side of her face down on the desk. I began thrusting myself deep into her as I held tightly onto her hips. The desk rocked with us. She was looking up at me from the very corner of her eye, not pressed against the desk and her mouth lolled open as if to say “Oh!”.

She commanded me to fuck her harder, to fuck her deeper, to fuck her faster, to fuck her until she couldn’t take any more. She pushed her pussy back onto the full length of my shaft, and for a couple of minutes, I thought I might ascend to heaven. I was inside her to the absolute hilt and we fucked with such a perfect rhythm that each stroke seemed to meld us closer and closer together. The squelching continued in unison with my thrusts, she was breathing heavily and her saliva was all over the desk, her face was covered in sweat and her clit was swollen.

As she pushed back into me and let out a groan that threatened to wake up my wife, I pulled out and took a step back, she positioned herself seemingly aware that my eyes were fixated on her perfect teardrop breasts, I covered them with spurt after spurt of my hot, creamy load. As I was ejaculating, she was writhing and using her fingers to further stimulate her soaking-wet sex. She was trembling to the sensations I imagined were deep inside her. For a while she seemed in a daze, but then raised her arms above her head, smiled and let me know that we were far from finished.

She now positioned herself sitting on the desk with her legs apart. She had positioned herself strategically in front of my office chair, and this was an invitation I couldn’t deny. Despite the softening of my previously rod-like cock, I was still incredibly aroused when she began playing with herself again, parting her labia to reveal a budlike swollen clitoris. I began kissing the insides of her thighs, and slowly made my way in between her legs. She tasted of sex. My mouth and chin were dripping in an instant, and my cock felt the first spring to attention as my tongue discovered her burgeoning clit. She pulled her legs back to afford me better access, and I probed at her until she dug her nails into my back.

Her nails generated a strange sensation somewhere between pleasure and pain. This feeling ignited an idea inside of me, in my desk drawer just to her left was the Birthday present I had planned to give my wife in just a few weeks. It was one of those vibrating massage wands that everyone understands the real purpose of. Talk about synchronicity - the sex gods where definitely smiling down on us!

I quickly removed the wand from it’s packaging and plugged it in. I twisted the dial which controlled the intensity of vibration and lightly placed it against her clit. Ohhhh more, more, she instructed as I turned up the dial. Her utterance of ooohhh fuuckkk during a deep exhalation was my confirmation that I had found the optimal vibration. I stood to get a better vantage point, and this afforded us the ability to re-position a little. I held one of her legs almost totally vertical against my torso, her other leg was tucked into her body with her thigh squashed against her breast.

I pressed the top of the wand harder against her clit and was able to position it so that it was partially inserted too. I worked my wrist up to a good rhythm and it was clear the intensity was to her liking. Her eyes rolled back in her head and she bit her lip in ecstasy. I continued working the tip of the vibrating wand inside, aiming it towards her g-spot. That’s when things went to the next level for her. She grabbed my arm tightly, appeared to stop breathing as if suspended in some other-worldly realm, then let out a huge moan! I stepped back, a little shocked by the loudness of her moan.

As I looked at her splendid shaking body, she began squirting huge gushes of liquid from her urethra, the first one hit my thighs, then my waist. She squirmed on the desk but kept squirting, destroying the paperwork I had last been reviewing based on a request from my boss. The desk was a total mess, covered now in a combination of our ejaculations. "Fuuuuucck me," she mumbled. After a few deep breaths, she climbed down off the desk and pressed her salty lips against mine.

We repositioned ourselves on the rug, and fucked as our tongues intertwined. This time we had adopted the simple missionary position. We took it slow, enjoying each other's every breath. I felt every millimeter of movement as my once again steel-like shaft penetrated her to the hilt. She was trembling and covered in sweat, her mascara was smudged and her mouth was agape. She was breathing hard and yet continued to grind down on me, appearing desperate to wring out my every last drop. Her nails dug into my skin. I rolled her left nipple between my fingertips and continued with our rhythm. We moved in unison, as if bound together like the mechanical parts of a steam train.

We reached our destination with one final orgasmic gush. It felt wrong, but so satisfying as I filled her up with my cum. I pulled out and watched as she deposited a large slimy pool onto the rug beneath us. She used her finger as if scooping the icing from a cake, and took a large glob up to her lips. Looking directly at me with panda-like eyes, she licked the wam silky ejaculate from her well-manicured digit.

We lay wrapped in each other's arms, totally removed from normal reality, and apparently oblivious to the fact that her best friend and my wife were lying just a flight of stairs above us. I only came out of our shared trance-like state when I felt like holding her in my arms til sunset. This caused me to jolt upright. I realized this could be the end of me...and definitely the end of us.

It took a while to clean up my rug. It took even longer to clean up the desk. As we slowly regained our composure, we shot each other occasional glances of disbelief at what had just happened. I have to admit that the sight of her did cause a late twitch in my spent cock, but I managed to dampen down the urge to act on it.

All was well with the world as I walked her out of the house to her car.

She opened her car door and asked me to let my wife know that she’d had such a great time and wanted to do it all again soon - I responded that my wife’s birthday would present the perfect opportunity, then grinned.

Before driving off into the distance, she looked at me with wide eyes and a smile of complete satisfaction.

Although it was still early morning, I knew it was going to be a great day!
