Two years ago, I decided my life needed a complete reset. My marriage had fallen apart, and despite a great MCAT score, I did not feel ready to take the plunge into medical school just yet. Finally single, I moved across the state and took an overnight shift in a small phlebotomy lab that ran tests for local clinics. Not only did keeping late hours pay better, the graveyard shift basically guaranteed peace and quiet. But I’ll admit it could get lonely sometimes.

But with the machines humming softly in the background, it was easy to achieve a perfect kind of concentration, in which I focused so hard I floated out my head. I was doing exactly that one night after loading some vials into the centrifuge, when the phone rang at 3 a.m.

I practically jumped out of my skin, and I hurried to grab the receiver.

“Hello?” I practically squeaked.

“Hi, it’s Cindy, right?” said the male voice on the other end of the line.

“That’s my name,” I replied. “Who’s this?”

“I’m Geoff, the guy in charge of the cold stuff. I just wanted to introduce myself.”

“So, you’re in the cryo unit?”

“Yup, I’m up to my eyeballs in frozen pee and semen over here.”

I laughed and said, “Well, Geoff, welcome to the team.”

“Thank you,” he said sincerely. “Look, I hope I didn’t startle you, but it was either a phone call or surprise you in the hallway. At least you know you’re not working all alone here anymore.”

“I really appreciate the heads-up, Geoff.” I paused, suddenly not wanting the conversation to end. I enjoyed the sound of Geoff’s voice — his deep timbre and playful nature drew me right in. I found myself wondering what he looked like. I cleared my throat and shifted the receiver to my other ear. “Hey, if you aren’t too slammed, do you want to meet me in ten in the lounge for coffee? I could use the extra boost for the homestretch.”

“Oh sure! That way you’ll know how to tell me apart from any skulking serial killers.”

I laughed out loud and told him, “OK, see you soon.”

On the heels of my divorce, I really wasn’t in the mood to date or start another serious relationship. But my cynicism was suddenly swept aside by a wave of hopeful thoughts, all triggered by that unexpected phone call.

Maybe Geoff was single. Maybe Geoff was good-looking. Maybe we’d hit it off. At the very least, I reasoned, I wouldn’t mind making a friend in my new city, one who also kept similar hours. It could be fun to explore new places with a pal.

Deep breath, Cindy,I thought to myself.There’s no reason to get all wound up — until there is.

But I didn’t have to wait long for Geoff to wind me up and leave me breathless with excitement. Our meeting was one of those rare and lucky moments where two people connect and experience that intangible but thrilling click. When I walked into the lounge and we locked eyes, I think we both felt it. But of course, we’re both socially awkward scientists, so at first all we did was smile and stare into our coffee cups.

I’ll start with the obvious, though: Geoff is a gorgeous man, with a full head of thick black hair, dark brown eyes and rich bronzed skin. Even that first time seeing him with baggy scrubs on, the obvious muscle tone in his arms and chest made me salivate a little — obviously the man worked out.

In fact, that was how we broke the ice and moved beyond just smiling and staring. I asked what gym he went to because I, being new in town, was looking for one.

“Oh, I train at the university gym, but also I’m in a running group and intermural rugby. I’m trying to do a triathlon this year.”

“Wow,” I said with a genuine smile. “That takes dedication.”

“Discipline, actually.” Geoff took a sip of his coffee. “Dedication, devotion — those are nice, but it’s discipline that really keeps things going over time.”

The way he said “discipline” sent an indecent thrill through me. Something about his tone made me imagine him as a stern taskmaster — one I wanted to obey.

I cleared my throat and brought myself back to the conversation by asking, “Is it like mind over matter?”

“It feels that way sometimes.”

Geoff’s eyes met mine again, and then they roved over my body. I felt myself blush hotly.

“Good training is really about being present in your body, moment to moment,” he explained. “Do you know what I mean, Cindy?”

By that point, my brain had shut off. I was only aware of my body: my stiff nipples grazing the cotton cups of my bra and the hot warmth growing between my legs. I inhaled sharply and realized I was still blushing.

“I think so.” I chuckled nervously. “I’m certainly not going for a triathlon, though.”

Geoff gently touched my arm and said, “No, no. I didn’t mean it like that. I hope you don’t think I’m one of those like super-crazy fitness nuts. I just do it to feel good.”

“I get it, and maybe you’re onto something anyway — all endorphins, minimal drama.”

“Exactly.” Geoff nodded. “But you know, drama’s not always a bad thing.”

I smirked and replied, “On that note, there will be a backlog of tests and plenty of drama if I don’t get back to work.”

“Of course.” Geoff stood up and held open the door for me as we left the lounge. “But if you feel like it, turn on your webcam. We’ve got Zoom. We can still talk, if you want company.”

“I’d like that,” I told him, making a point to “accidentally” brush against him on my way past. Hell, he was cute and sexy — it couldn’t hurt to flirt. “I could be the first-ever cam girl to broadcast from a lab.”

Geoff laughed, but from the way he looked at me, I could tell my flirty comment had sparked a compelling mental image. But there was something in his stare that told me Geoff likely had a kinky streak, and I hoped I’d learn more about it.

By the time I got back to my lab, Geoff’s Zoom invite was waiting on the screen. I clicked “connect” and waved into the camera as I said, “Hi again!”

Geoff waved back and said, “Wow, I love your backdrop. It’s so sci-fi in there.”

I had a nerdy spaceship pic, while his was a colorful nebula.

“Yours is great, too.”

“Hey, don’t sue me for harassment, but I gotta say something.”

“Uh-oh,” I teased. “Should I get my smelling salts?”

Geoff smirked and said, “No, but you’re like the sum of all my geeky fantasies right now.”

“What, me in my lab coat?”

“Yeah. A gorgeous redhead with bubble gum-pink lips, who is also a scientist. I mean, there’s no Marvel heroine ever drawn that could compare.”

“Hmm, maybe Dr. Jean Grey from The X-Men?”

“No, you’re definitely hotter, and please don’t get me fired for saying so!”

“I won’t,” I promised, and I meant it. All of our playful banter was turning me on, so his attention was definitely welcome.

“Good. Then … are you in the mood for a little fun?”

“Tomorrow night,” I said. “I really will catch hell if these tests aren’t finished.”

“OK. But for making me wait, there’ll be consequences,” Geoff replied, his voice a little husky. The sound gave me a thrill.

“I look forward to it.”

I ended the call and switched off my camera — and exhaled long and slow. I hadn’t felt so aroused in years. It was all I could do to stay focused, finish up my work and drive home to a hot shower and my vibrator. I masturbated while imagining Geoff delivering stern orders and disciplining me if I dared disobey.

The next night, an hour into my shift, another Zoom invite popped up on my screen. When the web cam flicked on, I saw Geoff seated in his swivel chair, with his lab coat on and his hands folded. He looked very, very serious.

“Good evening, Cindy.”

“Well, hello there.”

“Thank you for agreeing to participate in my study,” he replied in a business-like manner.

“Oh, and what study would this be?”

“I’m researching sexual arousal on the night shift.”

Instantly, my clit pinged with anticipation. We’d just met, and he already knew how to push my buttons.

“Oh?”

“Yes, but first there are a few preliminary questions.”

“Go on.”

“Did you masturbate last night?”

I licked my lower lip nervously and replied, “Yes, I did.”

“Why?”

“I believe … I was turned on. By you.”

“Do you think you might still be?”

“Yes, can confirm.” I smiled, but Geoff’s expression remained rather firm.

“Good. So we can proceed. Stand up and stay in view of the camera.”

“OK.”

“I want you to undress for me slowly, and as you do so, please point out your erogenous zones — the parts of your body that create the most arousal.”

“Well,” I began, moving aside my ponytail. “First, my neck. I really get turned on when someone kisses my neck.”

“Good, go on.”

I slipped off my scrub top and the slinky camisole beneath it, leaving myself in a bra. The cool air in the lab promptly gave me chills — and stiff nipples.

“I like it when my nipples get sucked — or pinched.”

“Show me.”

I unfastened my bra and teased him a little, playing peek-a-boo with the garment and revealing glimpses of my pale pink nipples. But Geoff reprimanded me for my cheekiness.

“This isn’t a striptease. This is a serious study. Lick and pinch your nipples. Show me how you get turned on.”

“Of course — I apologize,” I said, playing along. But his harsh tone made my pussy moisten even more.

From there, I followed his instructions, my cheeks flushing as I plucked and pinched my nipples. Under his watchful eye, I took turns lifting up each heavy boob and sucking each nub.

“Very good,” Geoff said. “Now keep going. Tell me about the rest of your body.”

Reluctantly, I stopped and traced my hands down my smooth belly. “I’m ticklish here, but I don’t mind when someone kisses me on their way down.” I pulled down my scrub bottoms to reveal my black cotton boyshorts. If they were a lighter color, the growing wetness of my flowing pussy would have been obvious.

“Keep going.”  

I kicked off my clogs and removed my undies, revealing my flaming bush. I now stood fully nude — save for my socks — in the lab. Never before had I been so turned on.

“You have a very nice pussy, Cindy,” Geoff said. “I see you’re a natural redhead, too.”

“That’s right.”

“OK, now it’s critical you follow my next instructions to the letter. Take the laptop and move over to that metal table. I want you to get on the table, spread your legs and let me see your pussy up close in the middle of my screen.”

With some careful maneuvering, I positioned the laptop between my legs and angled the screen so every inch of my soaking wet cunt was in full view.

“Good work so far, Cindy. Now, I want you to reach down and spread your lips and pleasure yourself for me. I need to see your exact process. But at no point are you permitted to bring yourself to climax. Is that clear?”

I sighed and said, “I’ll do my best.”

I parted my inner lips and let my index finger rest on the hood of my distended clit.

“I can tell you’re very turned on, but you must follow my instructions. Do as you would naturally — but do not come.”

In response, I moaned softly as my fingers stroked and manipulated the bud of my clitoris. With my other hand, I slid a finger into my pussy, teasing the sensitive opening with small butterfly strokes.

“Good,” Geoff said. “Now add another finger — show me how much you can open up your pussy.”

I obeyed, and with Geoff’s constant coaching, I soon ended up with three fingers in my cunt and a clitoris that felt like it was ready to explode.

“You’re doing great.”

As I moaned louder and louder, Geoff’s voice from the computer almost sounded far away, but just before I reached my peak, an alarm buzzer sounded and startled me.

I sat up to find Geoff smirking at me from my screen.

“Sorry, Cindy. But I knew I’d need something more harsh than my voice to keep you from straying off course.”

“I’m so fucking horny. Come on!”

“No, no, that’s enough for right now. You need to finish your work tonight.”

“But — .”

“I also insist you keep the cam on. That way you can’t cheat and make yourself come. Because I’ll be watching.”

Before I could protest further, Geoff held up his hand and said, “If you finish your work tonight without incident, I promise I’ll make it worth your while.”

And so began the longest shift of my life. It was all I could do to muster the discipline to keep my mental focus on the lab work — and on not on my soaked, throbbing pussy that kept crying out for attention. Oh, and if you’re thinking: Why not just go to the ladies’ room and come? Well, Geoff had thought of that possibility, too, and thus insisted on waiting outside the restroom and talking to me, so I had no chance of cheating.

Orgasm denial was a whole other kind of triathlon event — and while it was brutal, I’d never felt so present and alive. Not only that, but having a partner in charge of my pleasure was a total turn-on.

When the time finally came to clock out, I found Geoff waiting for me in the staff locker room. He pulled me into his muscular arms and bolted the door.

“You did amazing tonight,” he said in a voice laced with lustful praise.

I didn’t speak — I just kissed him.

We tore off each other’s scrubs and headed right for the shower, where he lifted me easily and I wrapped my legs around his waist.

“You have no idea how badly I want this,” he said, kissing the side of my neck.

“Actually I do.” But very quickly, Geoff wiped the smirk off my face as he pushed me against the wall and impaled me with his thick cock.

I inhaled sharply — my toys could not compete with his girth — and it felt so fucking good!

“Oh yeah — show me how you use those pussy muscles,” Geoff grunted as he pumped his cock into me.

I closed my eyes and clawed at his back with my nails. I felt my body completely taken over by the sheer force of his cock. His rugged, muscular chest grazed my sensitive nipples with every thrust, while he continued to hang on to me. The standing sex position is not for the weak-limbed anyway, but I felt like I was being fucked by a gladiator.

My pussy clenched around him so tightly that it seemed like I came in under 60 seconds. But of course, my iron man was nowhere near finished.

As I stood under the spray, Geoff took his time kissing his way down my body. When he reached my pussy, he lavished my cunt with a tongue bath unlike any other.

“Mmm, you make an excellent research subject,” he said, squeezing my swollen clit with his fingers.

“Well, I can’t say I’ve ever encountered a researcher like you,” I said breathlessly.

At those words, Geoff took my clit between his lips and sucked it so hard my knees buckled.

“Oh fuck! Please don’t stop.”

I ground my pussy into his face, desperately seeking another orgasm.

Still very much in control, Geoff pulled back, determined to put me through my paces.

“Do you need to come again?” he asked.

“Oh, yes!” I nodded. “And I want your cock inside me again.”

“Good things come to those who wait,” Geoff said, sliding two fingers inside me. “Such a tight and perfectly pink pussy.”

I whimpered and squeezed my nipples as he began to finger-fuck me, while relentlessly sucking my clit.

After I came for him a second time, Geoff stood up, kissed me and made me turn around to face the wall.

“Hold still,” he said, giving my wet bottom a series of hard slaps.

I was desperate for him and gasped as I felt his dick enter me again from behind, but this time he moved slowly, tentatively — as if he might pull out and deny me pleasure all over again.

“Oh please,” I moaned. “Fuck me, Geoff!”

My begging was met with another slap.

“You don’t call the shots, Cindy. You wait for instructions.” He gently tugged on my hair and nipped my neck. “Is that clear?”

I nodded and whimpered again as he reached around and pinched my nipples.

“Good. We’re gonna go nice and slow. I want you to savor every fucking moment now, so you can dream about it later.”

Inch by inch, Geoff teased me with his incredible cock, while he used one hand to casually manipulate my clitoris. It was the most exquisite torture and pleasure all in one. However, even Geoff couldn’t contain himself. Bit by bit, his thrusts increased in intensity, and soon enough he took me over the edge.

“Oh God, don’t stop!” I moaned as my body shivered with ecstasy. For the third time that night, I felt my whole being rocked by waves of pleasure.

“Ahhh yes!” Geoff groaned. He pulled out before he came and said, “I want you to take my cream.”

I eagerly knelt down and grabbed his cock, milking his shaft with my mouth and hands until pearly strands of come splashed across my lips. I reached between my legs and fingered myself as I lapped up his load.

“That’s right. Touch yourself while you eat my come.”

I licked my lips and swallowed his cock again, determined to make the moment last.

When we finally emerged from the locker room, the morning receptionist was on her way in.

“Hey there! You two are here late — or early,” she remarked.

“I suppose that’s just the nature of night shift. It can be rather all encompassing, you know,” Geoff said, glancing back at me with a smile.

“Yeah, it has a way of becoming a 24/7 lifestyle,” I added.

And without any hint of irony, I can say now that we have been living the lifestyle 24/7 ever since that wild night.
