To say that the day shift had been a rough one would be putting it lightly, tech students were worming their way around the labs unsupervised and it drove me crazy! I preferred working alone, in silence! It seemed no matter where I went, I just couldn’t get away from it. That’s why I agreed to cover the night shift when Susan called in sick that evening.

The thought of doing the night shift alone eased the tension in my shoulders. I watched people starting to leave the lab and I smiled to myself, thinking the less people around the better! I began my shift be walking the now quiet corridors, spotting one of two people but no one in particular. I hadn’t expected to see many people, that's why finding Sofia in the break room came as a surprise.

I entered and headed straight for the coffee machine but not without being noticed, as I'd hoped.

“Hey, nice to see I’m not alone on the graveyard shift!” she smirked and flicked through some paper work whilst clicking her pen.

“I like alone, especially after the day I‘ve had” I quipped and pleaded with the coffee machine to hurry up.

“Who else is on tonight?” she ignored my hints and continued to ask pointless questions.

“No idea!” I said bluntly, believing that would put an end to it but I was wrong.

“I’m only here to finish Doug’s paper work, anyone would think I‘m his secretary!” she complained and clicked the pen again in frustration.

I remained quiet, reaching for a stirrer while she continued to mumbled about how she didn't have her own office and that it must be bad for herhealth and safetybecause she was sat next to a chocolate vending machine and a large pot of ‘help yourself’ caffeine.

“Right, well, that’s just perfect!” I snorted and chucked the stirrer in the bin on way out. It was hard tolerating her for more than a few minutes, butif I'd thought about it Ihad nothing to complain about because if she was in here then I would have no distractions out there!

The first few hours past relatively quickly and the silence that haunted most people during the night shift only warmed me, I enjoyed my own company. But I knew I wasn’t alone, I’d noticed Sofia passing the lab window. The first time I saw her I thought nothing of it, until came the second time, a third and then a forth.

“Sofia, what was happening in the corridor earlier?” I asked as I moved inside.

“Huh?” she looked up, bemused by that fact I was actually asking her a question and not the other way around.

“No!” she slapped the air playfully “I was taking a break, from the break room.”

I laughed avertedly at her and she shrugged it off. I could tell she was amused by it. She told me that she had seen me in the lab, alone, but that I looked too busy for her idle conversation. It was my turn to shrug it off, I hated idle conversation and she knew it. I couldn't deny the truth in what she'd said, it was enough knowing that she was walking the corridor outside the lab let alone talking to me!

I left it at that and disappeared from the staffroom again. It must have only been about a half hour later when I heard the door blinds click against the glass as the door opened and closed. I knew it would be her, I didn’t even have to look up.

“Sofia? Does Doug know how many breaks you‘re having?” I said dryly, the irritation written all over my face and I buried my head back into the large microscope.

“Let me assure you, this isn’t a break, and this isn’t just idle conversation either!” she began, the smirk on her face evident in her voice.

“No actually, I need your help” she sighed to herself, like she had no choice but to ask me.

“What kind of help?” I asked witha tease in the tone of my voice.

“It’s for an experiment!” she replied and seemed to hesitate on her feet while waiting for me to answer.

“Hmm, Ok!” I accepted, though with an unconvincing smile. I didn't want her thinking she'd befriended me that easily.

Smiling at her successesshe led me down the corridor to the break room where she asked me to sit down, all the while telling me about the murder case that she was working on. Everything seemed genuine until she knelt down in front of me.

“… You see, the suspect had been sitting like this, and the girl, the escort, she had been kneeling in front of him like this” she looked up at me to catch my reaction, I nodded and then she continued “…and I was so wrapped up in thinking that he’d killed her that I hadn't considered something. Something that would clear him.”

“What?” I shook my head at her.

She raised an eyebrow at me and bitting her lip she pushed my legs openand adjusted herself between them. As if that wasn't enough, she lent forward so that her mouth was only inches away from my crutch.

“In most cases, if I guy was getting…”

I nodded before she could explain in detail. She could tell I was embarrassed by her position but she was enjoying it all too much to stop.

“The guy would most likely hold her head, right?” She said and reached for both my hands placing them on her head. For the sake of the experiment I obliged, allowing my fingers to run through her mousey blonde hair.

She shuffled her knees closer to me and I added pressure with my hands, making it clear I wanted something more. Her eyes looked up and she smiled devilishly before taking her hand to my waistband, unbuttoning my jeans and then pulling down the zipper.

I watched as she tilted her head closer again until she was only a few centimetres away and when her fingers pried at the waistband of my lace underwear I inhaled sharply. Almost instantly she sat up with a look of satisfaction on her face. I was completely baffled, and of course turned on!

She stood abruptly. “Thanks for your help” she said and acted as if nothing had happened.

“Sofia?” I insisted, I wanted to know what just happened.

“Well, you just proved my point. The suspect would've been too busy to strike her over the head, at least not until she was finished, right? And that’s the reason he had her hair caught in his ring, not because he had fought her in the struggle but because he was holding her head down, wanting more of her, like you were” she finished with a wink.

I smiled weakly and I stood trying to hide the blush in my cheeks as I headed for the door, though the sexual frustration in my walk was harder to mask as I scampered past her.

“Hey!” she called out and I looked back. “Next time we’re on a night shift together you might decide on some idle conversation after all, maybe join me for a coffee, or maybe, another experiment?”
