The harder I sucked and licked the harder it became to keep control over her body as her hips bucked and thrust; I had my hands wrapped around behind her, squeezing hard on her butt cheeks to try to keep her still so that I didn't lose contact with my tongue.
She dug the fingers of her left hand deep into my hair, pressing hard on the back of my head to hold my face tight up against her pussy while her other hand clamped down over her mouth to keep her whimpering breaths from turning into moans or screams. The sounds of people still milling about the office and occasionally walking up and down the corridor, right on the other side of the door, were a clear reminder of how much of a risk we were taking; something that excited us both even more.
Her eyes were squeezed tightly shut and I could feel her legs giving way as her knees tried to clamp in together but were held firmly apart by me crouching between them. Her thighs shook as I worked harder and faster with my tongue, praying for her to cum soon to alleviate some of the pain growing in my jaw from the constant work.
My prayers were answered after only a few more seconds. Her entire body convulsed and quivered as she let out a barely stifled squeak that, had it not been for her hand clamped tightly over her mouth, would have been a full blown howl. I felt the muscles in her pussy spasm and contract, forcing out a small jet of creamy fluid that trickled down my chin and dripped onto the carpet.
Her body continued to convulse as I continued to lick furiously until she couldn't take any more and she dragged back on my hair to pull my tongue away from her clit that was now too sensitive to touch. I sat back on my heels and simply looked up to admire the view as she tried to regain her composure, her whole body still twitching. I focussed on the view of her perfect pussy, flushed pink and glowing as the mixture of her juices and my saliva shone in the light.
When her eyes finally fluttered open again her hands massaged their way down her stomach and thighs as she leaned down to pull her jeans and thong off over her shoes. She straightened back up with a look of deep satisfaction shining out from her striking blue-green eyes. That look quickly gave way to one of fiery, animal passion as she leaned down and dragged me back up to her, ignoring the taste of herself on my lips she drew me in for another deep, ferocious kiss.
Her hands flew down and frantically worked away at my belt buckle and the buttons of my trousers. When she had them all free her hand shot into my boxers to squeeze and massage my cock. I couldn't contain myself and let out a deep moan.
"Fuck me!" It came as a desperate whisper, right in my ear, half begging half ordering.
She crouched down to pull my trousers and boxers down and over my shoes so that I could move freely, both of us now completely naked and vulnerable in the office with our colleagues wondering around just outside the door. The excitement was giving me an adrenaline rush well beyond anything I'd ever experienced before. I dragged her back up to her feet and spun us both around so that I could push her back onto the desk in the middle of the room. She sat on the edge and wrapped her legs around my waist, locking her ankles together behind my back, while I used my hand to position the tip of my cock just on the edge of the entrance to her soaking wet pussy.
As I pushed steadily forwards with my hips the tightness of her muscles wasn't enough to outweigh the wetness and I slid in with minimal resistance. She gasped and her eyes fluttered as I drove as deep as I physically could, until I could feel my balls pressing up against her butt cheeks. I pulled slowly back again, until only the tip of my cock was still inside her, before thrusting back in, over and over, getting quicker every time.
Her hips were bucking forwards to meet mine and she was using her legs to add power to my thrusts from behind. Her hands were around my back, her nails digging in deep, and her eyes were screwed tight shut as she gasped and squeaked every time my cock plunged forward into her.
I could feel my own orgasm starting to build, an overwhelming sensation forming at the base of cock and spreading out and down my legs, making it hard to keep a steady rhythm. I dug my fingers into her hair and pulled her body in tight against mine as the orgasm grew out of control, pulsing out along every nerve ending in my body. I could feel my own cum explode out of me and deep into her, a final sense of elation flooding my body and mind as we both clung to each other, gasping for air.
I have no idea how long we stayed like that, locked together in a tight embrace, still with me inside her, as our heart rates slowly returned to a safe pace and our breathing slowed down enough to speak. We pulled apart, just enough to share one final deep kiss, before she opened her legs to allow me to step backwards and slide carefully out of her, a white trickle of our mingled cum flowed out of her and dripped down onto the floor.
I picked my boxers up off the floor and used them to clean myself off while she stood up; another drop of cum flowed out and started to run down the inside of her thigh, making her giggle. I used the boxers in my hands to wipe it off, making sure to rub softly over the whole of her pussy on the way past, flashing her a cheeky grin as she twitched from the contact with her clit.
"I don't think we have time for any more."
"Pity. But you're probably right." I picked up her underwear, handing her bra up to her while I encouraged her to step into her thong so that I could pull it up over her hips for her, giving her pussy one last kiss before it disappeared from view. I passed her over the rest of her clothes and pulled on my own trousers, stuffing the cum soaked boxers into my pocket.
When we were both fully dressed and looked almost presentable she opened the door and poked her head out to check if the coast was clear. I stood behind her, waiting for the all-clear, and placed my hand on her bum, making her jump slightly at the unexpected contact.
"Oi! You've had enough of that! It's clear, let's go."
"Like I'll ever have enough! Go on then, lead the way." She stepped out into the corridor and sure enough, luckily, there was no one to be seen. She winked at me and disappeared down the corridor in the direction of her office. I took the time to appreciate the view of her toned butt in her skin-tight jeans before turning away to go back to my desk and gather the last of my things and say a final farewell to everybody before walking out of the door for the last time.
