“It won’t go down!” I said.
“I really think I need to go to the hospital.”

~~~

We had conducted several clinical trials, and the serum was safe. We were getting everything ready to submit our results for approval to progress to a larger test group, until tonight. Dr. Brandt and I were still in the lab, writing our reports well past midnight, excited to present what we had found.

I was a third-year research assistant for a leading pharmaceutical company. We were working on a new product that would increase the libido in both male and female consumers. One product in the form of a lubricant that would benefit both partners within seconds of application.

To keep an impartial perspective, Dr. Brandt and I did not participate in the trials. We wanted to remain objective, observing and documenting the results. We were very optimistic about what we had seen. Participants, both male and female, showed signs of arousal almost immediately following application. They reported sustained effects lasting from between fifteen and sixty minutes, depending on the amount used. We ran trials of individuals using it alone, which led to some intense masturbation sessions, and couples using it together with “mind-blowing success” as one couple reported.

“Shit!” exclaimed Dr. Brandt.

I looked up from my laptop and saw her across the lab, staring down at a pile of broken glass on the floor. She was wearing all the PPE required when working in the lab, so I felt sure she had not been exposed. She had been labeling samples and categorizing them when she dropped one. She was standing near the fume extractor, which wasn’t necessary as our tests only showed effectiveness with direct skin contact.

My concern increased when I heard the extractor power down. As the exhaust fans came to a stop, we remained motionless, looking at each other. Dr. Brandt stared at me through her face shield and N95 mask, and I could see the panic in her eyes. I ran to the shelf and quickly put on my own mask.

“We should be ok.” I said.

“We tested the serum, and it is only effective with direct skin contact or when aerosolized, right?” asked Dr. Brandt.

I didn’t answer.

“RIGHT!?” She almost yelled with panic rising in her voice.

“We tested direct skin contact and aerosolized particulates. We never tested if the fumes or odors created airborne contamination, but it is possible in these concentrated samples.”

Knowing the effects usually took seconds to show symptoms, we stood still, staring at each other, counting the seconds, fearing we were exposed.

I first felt my skin flush, and sweat began to bead on my forehead. I thought it could have been a result of my own panic, but then everything went wonky. I felt like I was suddenly at the bottom of a swimming pool. I felt pressure around my head, and sounds were muffled as if someone had their hands over my ears. Then just as suddenly, everything became crisp and clear. Colors were more vibrant, sounds were sharper, and I could smell Dr. Brandt from across the room. It wasn’t her perfume, lotion, or the detergent smell from her clothes. It was her. Her scent, or more precisely, her pheromones. My scalp began to tingle.

Dr. Brandt leaned forward with her head down, palms flat on the lab table. I assumed that I was exposed since I had not been wearing any PPE when she dropped the vial, but I wasn’t sure if Dr. Brandt had been exposed. She was closer to the spill but was wearing a mask. I watched her for a moment and noticed her breathing was rapid and she was shaking her head slowly.

“Stupid, stupid mistake.” She was saying over and over to herself.

I grabbed bleach spray, nitrile gloves, and other cleaning supplies and approached Dr. Brandt. She was still standing above the broken glass and the small puddle of liquid on the floor. When she noticed me cleaning the floor, she widened her stance and moved back half a step to give me more room.

After I cleaned the floor, I looked up and saw that she was staring down at me with wide eyes.

“We are medical professionals, research scientists, we can do this,” she said in a low husky voice.

As I slowly stood, I could feel the heat radiating from Dr. Brandt. I could smell her, I could taste her in the air, and it was intoxicating. There was an electricity between us that made me want to touch her to ground the charge. I had to be careful as I wasn’t sure if her PPE protected her, and maybe she wasn’t exposed.

“Are you O.K., Doctor?” I asked.

“I think so,” replied Dr. Brandt. “Are you?”

“I believe so,” I replied, ignoring the symptoms I was feeling.

“Are you sure?” Dr. Brandt said as she looked down, below my waist.

I looked down as well and was surprised by the outline of my erection in my pants. I was wearing a pair of loose-fitting hospital scrubs that were clearly tented and straining to contain my penis. I had no idea that I was so erect. Embarrassed, I tried to cover it and turn away.

“Fascinating,” said Dr. Brandt.

“Are you feeling symptoms? Obviously, you are feeling something.”

I definitely felt strange. I had this overwhelming urge to release my erection from my pants and rub it on something, anything. Like a maddening itch that needed scratching, and I couldn’t think about anything else. I tried to reposition my cock vertically under my waistband so it wouldn’t be so obvious as Dr. Brandt continued asking me questions. It appeared that her N95 and face shield had protected her, or at least it seemed that way.

“This is an amazing discovery. We need to take notes and document this.” Said the doctor.

“Tell me what you are feeling.” She continued as she picked up a notebook and pen.

Touching my penis through my pants felt too good to stop. Repositioning my throbbing member turned into a prolonged touch. With my back to the doctor, I lowered my waistband and released my cock.

“Please talk to me.” I heard Dr. Brandt say as I felt her hand on my shoulder, lightly turning me to face her.

I had gripped my cock with my right hand and was slowly stroking it from tip to base. I felt like I was in a dream state, unconcerned about my exposure or my self-pleasuring in front of my coworker. Dr. Brandt looked down and watched for a moment before starting to write in the notebook. I tried to speak, but it was hard to form words. I was only able to reply, “It feels so good,” but that was all.

Similarly, Dr. Brandt said only one word, “Fascinating.”

Dr. Brandt led me to a nearby table and positioned me so I was partially sitting on its edge as I continued to masturbate. I was aware of what I was doing, but my only thought was to increase my pleasure and nothing else. The doctor frantically wrote on her notepad as she connected a blood pressure cuff and the EKG leads. She settled into alternating between checking my vitals and watching me with her notepad in her lap. She would raise her eyebrows when I changed speed or technique. I heard a little breathy moan escape her lips when I dropped my pants to my ankles and started caressing my balls.

She set up a video camera beside her and started recording. Watching her bend over to tuck the power cables out of the way brought me to my first orgasm. She heard me grunting and looked at me and noticed I was staring at her ass as ropes of cum ejected from the tip of my cock. I was thrusting my hips into my grip as my cum landed on the ground near her feet and ran down my knuckles. She stood up, grabbed her notebook, and started writing again before getting out her phone to take some pictures.

I started to relax a bit after my release, but my erection did not subside. The doctor asked me for an update, but I could only continue to masturbate. Normally, after an ejaculation, I would lose my erection and feel satiated. But this was not normal. I felt even more aroused than before my orgasm, and my cock was equally erect.

The semen I was using as lube was starting to dry up and chafe me a bit. Dr. Brandt noticed my discomfort and sprinted to her desk. She returned with some lotion that she thankfully squirted on my cock as my hand worked furiously. It felt great, but I could tell that my orgasm was a long way away. I tried to stop, but every time I released my grip on my cock, I had an overwhelming desire for stimulation and started back up again.

I told Dr. Brantd that I needed more. She frantically looked around the lab for something that would add to my stimulation, but there was nothing quickly available. In the exam rooms, there were magazines and DVDs for the test subjects. but not in the research area we were in. Dr. Brandt grabbed her phone and tried to search for something pornographic to help me, but was having trouble seeing her phone screen through her plastic face shield. Without thinking, she removed her face shield and her N95 mask and tossed them to the floor.

I released my cock again and let it bob out in the open, but the way Dr. Brandt just stared at it made me feel the desire to stroke it again.

“Please help me.” I pleaded with her as I rubbed the remaining lotion into my frenulum.

Dr Brandt staggered for a moment and rubbed her temples, obviously experiencing her own symptoms. Completely distracted by my performance, she had exposed herself to residual airborne contaminants when she removed her PPE.

She held out the bottle of lotion and proceeded to squirt several pumps onto my cock. She set the bottle down and removed her glasses. She then started to unbutton her blouse. Slowly, she revealed a black lace demi cup bra that left the tops of her nipples exposed.

I felt closer to a release, but not close enough. Dr. Brandt unzipped her skirt and let it fall to the floor. With each of her actions, she created a reaction in my intensity. We played the game back and forth until she and I were both naked in the lab. She had stopped taking notes and had begun caressing her breasts as she watched me masturbate. I watched as her stoic expression faded into one of wanton lust. She was very attentive, alternating between adding lotion to my cock and touching herself, which helped me as much as the lotion did.

“I need more,” was all I could say with a look of desperation.

Dr. Brandt stepped closer to me and cupped her full breasts with both hands, lifting her nipples as if offering them to me. I kept stroking my swollen cock, but pointed it at her crotch as she widened her stance, straddling my legs. I could smell her sex, which sent my already maxed-out sex drive into a whole other gear.

I pressed forward, rubbing the tip of my cock between her legs, noticing the tip glistening with her moisture. Dr. Brandt placed her arms over my shoulders, around the back of my neck, and lifted herself onto me, wrapping her legs around my waist. She was so wet that I easily slid inside of her, causing us both to shiver.

I reached under her legs and placed a hand on each of her ass cheeks and stood, holding her fully seated on my erect member. She released a deep moan and nuzzled her face against my neck. I stepped forward until she was pressed against the laboratory wall, giving me resistance to push against. The friction and feeling she gave me as her folds accepted me was far better than what my hand provided.

My senses were heightened, and I could feel the details of her vaginal canal as I thrusted in and out of her. I could feel her cervix when I bottomed out, and I could feel her G-spot glide across the head of my cock as I pulled almost all the way out. With each thrust, I felt Dr. Brandt get wetter and wetter until I could feel her juices coating my shaft, balls, and running down my thighs. Her moans turned to screams as an explosive orgasm tore through her, urging me to plow harder into her. I ground my pelvis against her as hard as I could, trying to force myself deeper inside of her. Finally, I felt the long-awaited spasms begin as I released my cum inside of her.

I slowed my pace but kept moving in and out of her as she continued moaning and writhing on my still erect member. She did not show signs of slowing down, and I was happy to provide something for her to grind on. We continued to ride the wave, assuming that our symptoms would eventually subside, but until then, we would continue the experiment.
