It was towards the middle of December… at the time when there’s not much left at work to wrap up and it’s too late in the year to start any new projects. The time when long lunches and leaving early aren’t too much of a problem.

I’d (M28) been hooking up with Michelle my FWB (F35) on and off for a while. Simply put, Michelle was an absolute MILF. Long dark hair, dark eyes, tanned skin and a figure that hid the fact that she was mom. Gorgeous legs and a tight little ass made her the perfect package!

The best thing about Michelle was her no-nonsense approach to our arrangement. She was always straight up about what she wanted when. I’d see her name pop up on my phone and I’d know I’d be balls deep in her within 24 hours… it was just that simple and easy. So when I saw her message pop up on this day, I knew I was in for a treat. On this occasion, she’d just moved into a new office, and had given the brief that it needed to be broken in.

I dashed out of the office the second my lunch break arrived and was over at her office in minutes, only for a minor disaster to have struck. A couple of staff from the neighbouring office had popped over with a glass of champagne to welcome her to the building. To be polite we chatted and did the customary small talk thing, which was taking faaar too long for my liking… so I slipped to the bathroom and sent her a photo of my dick throbbing in anticipation of what I knew lay in store… I got back, saw her briefly open and see the photo and then stammer as she tried to hide the distraction, barely a minute later excuses had been made and we were charging up the stairs…

The door had barely slammed and we were all over each other, kissing passionately as our hands roamed over each others bodies. It didn’t take long for me to her to hitch up her skirt and begin rubbing her drenched pussy through her panties. She immediately grasped at my belt and buttons on my pants, frantically clasping at them until she’d freed my cock and began stroking it. By now my hand had slipped under her underwear and I had two fingers working away inside her… she stopped us for a second, slipped off her panties, hopped onto her desk, grabbed my cock and said “just fuck me already”…

In a heartbeat I was between her thighs and had her guiding my cock into herself. She moaned out loud as she slipped over the head of my cock and I began to slide deeper into her. Moments later I was thrusting into her frantically, we’d both been so desperate to fuck each other’s brains out that we couldn’t help but get straight to hard and fast. She clutched at the edges of the desk, moaning as I pounded away, not giving a fuck if the neighbouring offices could hear us… A little slip led to her bending over her desk, and I didn’t need any more encouragement…

Sliding into her soaking pussy once more, it didn’t take us long to get right back to that same frantic rhythm. Ramming into her from behind grabbing a fistful of her hair is something that will be burned into my memory forever… I’m lucky that given the girth and curve of my cock, doggy tends to hit all the right spots and Michelle was no exception… I felt her begin to shudder a little and then felt her tighten and clench around me as she began to cum… determined to push her well and truly over the edge, I gripped her hips and pumped harder and faster. She responded by melting into a dripping mess of shaking and gasping for breath as she was overwhelmed d by her orgasm.

Needless to say, the increase in intensity and her body’s response set me off completely. I felt my balls tighten and as soon as my cock twitched for the first time I knew I was going to explode. My cock throbbed and pulsed, as it began pumping shot after shot of cum into her, ultimately leaving her a wet mess of the mix of our cum… Pulling out slowly, I made sure to let some dribble onto the desk, just to make the office warning official…

We quickly straightened ourselves up and headed downstairs, hoping our absence hadn’t been too notable. But not before I pocketed her panties, insisting that she’d be able to feel my cum easing out of her and down her thigh for the rest of the afternoon… As we made our way back to mingle among the rest of the gathering I saw her glance at me, almost purring from the combination of afterglow, our secret and the sensation of carrying my load inside her…

I had to head back to my office soon after, but she had one last twist in store for me… As I sat down at my desk, I saw a text from Michelle… when I opened it, I saw a picture of her spread pussy with my cum leaking out of it, taken in the bathroom… The caption: “I’m going to need those panties back, after party at mine later”…
