I was not long out of university and working in an office. There were several late-thirties, married women working there too and they had taken to using me if they were feeling horny. So far, this had been confined to kissing and some harmless groping in the office kitchen.

My name is John and I was the office junior, so was asked to decorate the office for the annual Christmas party. One of the ladies, Karen, a beautiful woman with long sexy legs, who always dressed sexily, volunteered to help me and joined me in the store room to collect the decorations. She had a sexy glint in her eyes as she closed the door behind us.

“Hold the ladder while I get them,” she told me and I did as I was told but, when she got to the top, I gasped as I saw that she wasn’t wearing any panties, and I could clearly see her smooth, shaved, married pussy under her short skirt.

“Don’t just stand there, help me down and fuck me, we don’t have long,” she hissed sexily.

As soon as she was down, I pushed her against the wall and drove my hand up her skirt roughly, sliding two fingers easily into her sopping wet pussy. Meanwhile, she tore at my trousers and released my rock-hard uncut cock, which she proceeded to stroke urgently.

Within seconds her skirt was up around her waist and she turned and bent over, pressing her hands against the wall to steady herself, and to give me easy access to her slippery hole. We groaned as my cock slid between the hot, wet folds of her soft, smooth labia and then found the entrance to her unprotected cunt.

Karen put one hand over her mouth to stifle a loud moan as I pushed forward and slid deep inside her, then almost hit her head on the store room wall when I withdrew and slammed back into her. I was soon fucking her urgently with hard, fast strokes as she pushed back against me, and could feel my cock touching her cervix with each thrust.

I reached underneath and pulled at her blouse, which tore open giving me access to her tits, I grabbed one as I held her hips with my other hand and Karen moaned as I tweaked her stiff nipple.

We were so consumed with lust that I knew we would not last long and, suddenly, Karen’s legs buckled as she came. This was too much for me and, holding her hips to hold her up, I grunted and started to spurt my warm potent semen inside her spasming, unprotected pussy. We both shuddered as we came together, letting the waves of orgasm crash over us.

“Oh my, I’ve never cheated on my husband before, but I really needed that,” she said quietly once our orgasms had subsided, I withdrew and watched her clean her spunk soaked pussy as best she could, before lowering her skirt and buttoning her blouse.

“Thank fuck you didn’t rip this, otherwise it would be too obvious what we’ve been doing in here,” she said as she climbed the ladder again to retrieve the decorations, I could smell the sex in the room as we finished adjusting our clothes and got ready to leave. Before leaving, I leaned forward and kissed her, and she responded passionately, as I held and squeezed her ass over the short skirt, that had only just been re-positioned.

“When can I fuck you again?” I asked softly.

“There’s always the Christmas party, I’m planning on staying in a hotel, so we’ll have all night if you want,” she said slowly and sexily.

“Mmmm, I want to take more time, next time, and perhaps get to taste that married pussy,” I whispered.

“Christmas is a time for getting what you desire,” she giggled and left the store room with a sexy wiggle of her ass.

“Fuck, I can’t wait,” I said quietly and followed her back to the office.
