Showed my co-worker my pussy to calm him down…

Sooooo after that first time in the supply closet, I couldn't stop thinking about it. Like, all week. It replayed in my mind at the most inappropriate times. Meetings, whilst typing up reports, even while trying to make small talk by the coffee machine.

Three times that week I'd found myself in bed, panties around my ankles, remembering the look on Tom's face when I'd exposed myself to him.

One week later and he was looking better, more like his old self. He'd even joined in with some office banter that morning. But now, midway through Friday, he was looking at me earnestly.

"Hey Sarah," he said, his voice casual. "I need to grab some supplies from the closet. You know where the good pens are, right?"

I felt a blush creeping up my neck. I glanced around the office, and once again, everyone was absorbed in their work, no one paying us any attention.

"Sure," I said, trying to sound equally casual. "I can show you, if you want?"

“That would be perfect.”

We stood up almost simultaneously, and I led the way down the hallway, my heart thumping hard. I could feel his eyes on my back, on the sway of my hips in my pencil skirt. I fought the urge to exaggerate my step, to swing my hips from size to size and allow him to observe the jiggle of my ass.

At the supply closet door, I entered without looking at him, too ashamed and embarrassed to make eye contact. Instead, I simply made my way to the pens and bent at the waist to pick them up.

But not before pulling my skirt up around my hips.

I heard the sharp intake of breath behind me, and I didn't have to turn around to know he was staring, the sheer mesh of my panties disappearing between my cheeks.

“Fuck,” Tom whispered from somewhere behind me. “Your ass is even better than I’ve been picturing it…”

“You’ve been picturing it?” I asked, feeling the flush creep higher up my neck. “That’s interesting…”

I began to gyrate my hips slightly from side to side, my heartbeat loud in my ears, the thrill of having my ass exposed to him immediately making me wet.

“Why don’t you come and feel it?”

It was a terrible idea, and we both knew it.

"You...you're serious?" he stammered.

“I said I’d help you…” I arched my back deeper, pushing out my ass, popping my pussy. I looked back at him, a few strands of hair falling across my face. “That’s why you wanted me to come here, isn’t it?”

He nodded wordlessly. I turned away from him again, my vision filled with rows of pens, highlighters, and calculators. I smiled.

“Then fucking do it.”

He slipped under the fabric of my skirt, lifting it higher, exposing more of my panties, his warm palms making contact with the cool, smooth skin of my lower back. I let out a soft sigh as his hands began to explore, moving downward, caressing me, squeezing the soft flesh of my ass.

I felt like such a slut.

"You're so soft," he murmured, his confidence growing as he squeezed. He kneaded my cheeks, pulling them apart, his knuckles brushing against the soaked fabric of my panties. I wondered how often he had thought about this moment since the last time we spoke, and I couldn't help but let out a low moan.

"Do it," I commanded, my voice filled with a desperation I didn't know was going to be audible. "Pull my panties down."

His hands fumbled with the delicate fabric for a moment before he managed to hook his fingers into the waistband. He pulled my panties down slowly, exposing my bare ass. I shivered as I felt the fabric fall loose around my knees, then down to my ankles. I stepped out of them.

“Pick them up,” I said with a slight gasp.

“W-what?”

“You heard me,” I said, gyrating again. “Put them in your pocket for later.”

I felt him drop to one knee, doing as he was told, and I knew that for a split second he was eye-level with my dripping pussy, and I wondered if he was considering sticking his face between my cheeks. The thought of twerking my ass and pussy on his open mouth made me shiver, but no sooner had he dropped to pick up my panties than I heard him stand again.

I opened my mouth to speak but his hands were on me again immediately, this time without any barriers between us. He squeezed my cheeks, his thumbs pressing into me, pulling my cheeks apart.

"Take it out," I moaned, my hands gripping the shelves for support. “I want to feel it.”

This time, he needed no clarification, and I heard him unbuckle his belt behind me. My heart hammered against my ribs, but I forced myself to stay bent over, my palms pressed flat against the cool metal of the shelving unit.

Then I felt it. The hot, hard length of his cock nestled between my ass cheeks. He felt big, thicker than I'd expected, and once again a soft groan escaped my lips as he just held himself there, letting me feel the weight of him against me.

"Fuck," I whispered. “This is so wrong.”

“I know,” he said, his cock twitching as he said the words, the thrill and the naughtiness obviously getting us both off.

“No sex,” I said, pushing my hips back slightly, beginning to move in a slow, deliberate rocking motion. “I’m not like that. I’m a good girl.”

“Okay…” he said as he began to move with me, his hips thrusting gently in time with my rocking. His grip on my hips tightened, his fingers digging into my flesh, holding me in place as he established a rhythm. I could feel my own arousal dripping down my inner thighs, my clit throbbing with every movement.

We started to speed up, his thrusts becoming more urgent, more desperate. I knew what he wanted. What we both wanted.

"Sarah," he grunted, his voice strained. "I need to be inside you. Please."

I looked back over my shoulder, my hair a messy curtain around my face.

"No sex,” I repeated. “Not here.”

I didn't give him a chance to argue. I started moving again, faster this time, my hips rocking back and forth with renewed purpose. I was in control. I was the one setting the rules. And the rule was that I was going to make him cum with my ass.

I reached back with one hand, placing it over his where it gripped my hip. "Just enjoy this, Tom. I want you to use me."

His thrusts became frantic, his breathing ragged. I could feel him pulsing against me, getting harder, closer. I squeezed my cheeks together as tightly as I could, creating a hot, tight channel for him to fuck.

“Show me how much you like it."

With a final, guttural moan, he did, and I felt hot thick spurts of his cum hitting my lower back, immediately regretting my decision, immediately filled with horror at the thought of walking around the office with cum on my shirt. At least it was Friday…

I continued to gyrate him through it, milking him with my ass, rocking slowly until his body shuddered and he was still, spent and panting behind me.

Slowly, carefully, he pulled away. I felt the cool air hit my wet, cum-covered skin, and I shivered.

His face was flushed, his eyes wide with a mixture of awe and disbelief.

“Now, let's get back to work. And don't forget my panties…”

[Once again, there is more if you wanna hear it!]
