Get what he needed

"Hmm... Ethyl Acetate, Propylene Glycol.. Thyroxine and Benzaldeyde?" she curiously asked while reading from my hand written list. "quite the shopping list you have there. Glad to see you spent at least some time learning from me and not just staring at my ass."

My eyes immediately looked up from her ass, "Aye - always the multitasker wasn't I?"

"Oh my god, you're horrible.." she said smiling ear to ear. I was certainly not used to seeing this side of Ms. Markle but I rather enjoyed it. She spoke the same language of Chemistry, her wit was always sharp and really - she wasn't bad to look at either. I figured she is enjoying the attention and a little harmless flirting never killed anyone. Except for... well, yea guess it probably has - jealous boyfriends and what not.

"OK here is the last of them. I am a little concerned with your intentions however - its against my better judgement to give you access to all these hormone compounds but... I feel like I can trust you Michael. What is it that you're working on exactly?"

While I had told myself earlier to keep the Axe spray a secret if she asks, I was just too proud of my work not to share the success with the mentor who had started me down this road.

"It's really fantastic Ms. Markle. I resynthesized a base compound designed to deactivate an enzyme blocker in certain receptors. Here..." I started to explain while loading my backpack with my supplies before showing her the Axe spray.

"But Michael - Deactivating? Normally you want to activate blockers..." she pressed.

"I know, thats whats so great about it. Think about how the brain naturally blocks some amount of pain. A pain killer just helps block even more pain receptors. This will do the opposite, allowing 100% reception and not blocking anything at all - but instead of pain receptors its the receiving receptor for... um, other things..."

"So these other receptors would become uninhibited? Free to fully experience a perfect chemical reaction, with no dilution?"

"Exactly!" I explained as my excited hands fished around my backpack to show her the product. But to my shock, all I felt was a slippery and wet pool at the bottom, slightly leaking out. The wetness on my pants, now it's covering my hands...

Fuck! The Axe can is leaking!

I turned around to explain that I needed to leave, but now Ms. Markle was standing inches away from me, her neck and face flush red. She had grabbed ahold of my wet wrist, lifting it up inbetween us. Bold eyes examined me thoroughly and in wonder.

"If that worked - it could be a pure synaptic channel for serotonin, dopamine - pleasure... Michael, the things someone might do to get this... the things that someone's brain might do to keep it. Hallucinations, fantasies, memories - all could bend..." she paused under the influence as she craved a taste from the fluid dripping down my hand.

"The mind can bend what pleasure is with the right chemical demand." Her nostrils flaring at the thought.

"Please, Ms. Markle - I have to go now, really I just -" But before I could utter another word, her juicy wet lips wrapped around my index finger. Slowly sliding on up to the very top, her tongue looping around the tip as she then dragged those aroused lips down to the other side. My cock stiffened like it had just woken up from a deep slumber. Her right knee crept along my side as she greedily sucked down every drop on the next finger now.

Pulling my hand back only brought her face closer to mine, she wouldn't let go as she cherished each drop. This had to stop, but I was dealing with a chemical override of my own now. Her head now bobbed up and down to my next finger, more aggressive and passionate now.

Lots of words to make her stop had bubbled up into my mouth - but were swallowed with each gulp.

Until she looked at my last wet pinky finger, and then looked up to me. Her eyes were a hungry hunter viciously determined, cornering her prey. My last defense was to submit. I locked eyes with her as I brought the axe soaked digit up to my mouth, just inches from hers. Defiantly, I smeared the remaining juices across my lips as she pounced.

We began violently kissing, her colored fingernails clawed at the back of my head to press even harder into her lips. It felt amazing as she tried to suck the energy out of me. I felt her skirt being pulled up to bunch around her hips, her body's momentum pressing desperately on my hard cock. I could barely breathe as she fought to get me inside of her, my full erection raging out over my boxers now, somehow only pulled down over one of my butt cheeks.

Glass beakers and samples began to fall and some even shatter as we shook the shelves. Her legs wrapped around my waist as she lifted her hips into the air, pressing into my belly and begging me to meet her just another inch into her swollen body.

"I've wanted you for so long Michael. I've always wanted you. Please. Please. Take me. Right now!!" she chanted into my ear. But before I could even decide, I felt her hungry body wrap its wet grasp around my cock.

"Holy fuck..." I said, closing my eyes and letting her begin to ride me against the shelves. Her hips began to slam against mine, wet and sloppy, fucking furious. I lifted her with each bounce, hands supporting her passionate grinding on my body. I grabbed her ass and squeezed down unapologetically hard. She was looser than girls my age, but knew exactly how she needed to move to get her off - Someone who confidently knows their own body. I stared at her mouth, at each shape and contortion it made as I plunged deeper inside of her, ramming against her g-spot.

Manicured fingers reached down and began quickly rubbing her clit, commanding me "Keep going, don't stop. That's it!" She was finding her groove, using my cock as a mounted key to unlock a hidden orgasm just outside of her reach. "Getting close, don't you fucking stop." she yelled now. I pounded away like a work horse, keeping her dirty words close to my ear.

It was getting me close, but I knew what would really get me off.

"Yes you like that baby? Yea - Ria I want you to cum. Cum for me baby." I replied in fantasy, knowing the best way to get me off. Her fingers kept going through exhaustive peaks as she furiously rubbed and clenched down on herself.

"Oh my god.. Ooh my gooooddddd!!" she pleaded out loud. "More! Oh Michael - Thats it! Thats it!" she cried out as her thrusting rhythm peaked, gripping down intensley in full orgasm before - the rhythm finally started to fall apart. Each plunge now became slower and deeper, holding me in for a few seconds each time now.

I looked at her face, her eyes were heavy and silent as she just was washed over in a pure, uninhibited rush of an orgasm over every inch of her body. Her brain soaked in a marinade of endorphins right now, a slight drool even coming from her lips. She was dumb struck from every sensational chemical reaction.

I kept up a slow steady thrusting pace, my engines were still on and taking in the pleasure from it all. After she began to gain a little control of herself, we started to pick up speed once more. It was my turn to cum.

Or wait.

Should I?

I wrestled with the thought for a second. This is amazing... but... I knew I couldn't trust myself. I need to stop right now. I've got everything I need, I told myself I cannot cum, no matter what I have to stop and wait until I can see Ria.

I slowly start sitting up my stupefied teacher as she incoherently tried to ask why I was stopping.

There wasn't a chance to answer before the knock on the door scared us both. Coming from the other side of the room away from her office - the main laboratory door was begin questioned.

"Whats going on in there? I heard noises - Ms. Markle are you in there? Open up!"

Shit - Time to go! I grabbed my backpack with all of my supplies and quickly tucked my raging boner underneath my belt and pulled it back up. I started to head towards the office door as she began pleading.

"Wait!! Michael, NO! Don't go, come back here, let me have you again! One more time, that's it I promise just for a minute!"

I looked on somewhat sympathetically, she had the eyes of an addict begging for one more hit, and it was all because of me. "I'm really sorry, I've gotta go." I responded, truly feeling bad.

But she wouldn't hear of that. Her feet held her up as she asked again through clenched teeth. "Michael.. I'm not asking you. Come here now, let me taste it again!" now coming at me like a shot tiger.

I bolted for the door as she burst into pursuit. Her stride was ravenous, nails extended out and ready to get another fix. The sound of her feet were hitting the ground harder and faster than my own as I raced for the exit. "Michael! MICHAEL!!" She began shouting as I sprinted with all of my might. Her arms lifted up into the air as her mouth opened up in a shriek - The sudden THUD! when her body slammed into the now closed door. On the other side, I breathed out and used the security lock to seal it in place.

Her fists were animals pounding away but it would only be a minute before her senses would tell her to go grab the key on the floor, so I had to move quick. Racing out the office door, thankfully I saw no one around. But that feeling didn't last long, I overheard the in-and-out voice of a walkie talkie around the corner. A hall monitor? Or worse, could they have called the police already?

Shit! I looked at the first door infront of me and blindly ran head first into whatever room happen to be on the otherside.
