In the middle of the empty office after everyone else had gone home, she leaned back against me. I sucked hard on her neck and grabbed her tits, rolling her nipples between my fingers. My cock throbbed, nestled between her cheeks, and she swiveled her hips, grinding against me.

Her dress and lacey bra lay discarded on the floor next to my pants and shirt. My boxers had been flung across the room. She was still wearing a mesh thong and fishnets with garters. She knew the garters drove me crazy.

She gasped as I pushed her down in front of me. The desk was exactly the right height for her bend over. Excited, she reached forward to grip the far edge. Her breasts and stomach were flat against the desktop. I gripped her hips and pulled her roughly against me. My cock pressed against the already damp mesh of her underwear, straining at the thin fabric separating us.

I grabbed the back of her thong and tugged up so it pulled tight against her clit. I was rewarded with a surprised cry of pleasure. I loosened my grip and pressed my cock against her again, and then pulled once more on her underwear. I kept tightening and loosening my grip, rhythmically tightening the fabric against her. My cock still pressed against her, and as the fabric rubbed against the sensitive tip of my head, I could feel her get more and more wet.

Her breathing was short and shallow with anticipation when I finally pulled her thong to one side and rubbed the head of my cock between her lips. She was dripping wet, and parted easily around me. I pushed forward and felt the length of my cock easily slip into her. She gripped the edge of the desk even tighter and bit her lip as I pushed deeper and then started to fuck her.

It felt like her pussy was sucking on me. Her hot lips wrapped around my shaft, unwilling to release me when I pulled out and gripping tight when I pushed deeper. After a few minutes, she got up onto her elbows, grunting with each thrust into her soaking wet cunt.

Her breath came faster and faster until she suddenly cried out and arched her back.

The sudden motion caused me to pop out on my backstroke. Eagerly, I thrust forward, but with her back arched the angle wasn't quite right. My cock pressed firmly against something unyielding before slipping back into position. I felt a moment of resistance and then groaned as I slid slowly back into her enveloping heat.

She seemed even tighter now, and the sensation as I pushed into her was incredible. She was grunting and crying out in pleasure as I began to fuck her more quickly. She shifted her weight to one arm, and I felt her reach between our legs to rub her clit. Her hand moved faster and faster, in tight little circles until her entire body tensed. I could feel her fingertips brushing against my balls, and the extra sensation sent a surge through my system. I felt my cock swell inside her, and suddenly she swore loudly, her body shaking until she collapsed on the table, breathing heavily.

I didn't stop or slow down. I keep a tight grip on her hips and continued to thrust into the enveloping heat of her body. As I built towards my own orgasm, my breath became ragged, and I started to moan. She was gripping the edge of the desk with white knuckles. I was moving frantically now, and the wet sound of my body against hers seemed to fill the room. Nearly there, I gave her a quick slap on the ass and called her name. It gave me exactly the result I wanted as the surprise caused her to tense up and tighten around me. I felt my cock throbbing as I pumped my cum deep inside her.

After a few moments of truly intense orgasm, my vision cleared. I found she had relaxed and was breathing deeply, arms spread at her sides. I looked down to enjoy the sight of my cock in her pussy, only to discover that without realizing it, I had plunged my cock into her ass.

We had never had anal sex before, and the realization caused my cock to swell, eliciting a deep groan from her.

"If you ever do that without warning me again, you're fired... But damn. That felt incredible."
