I stood in the lab, theoretically paying attention to the monitors before me and crunching numbers. But really, I was surreptitiously checking out the various women entering and leaving Mrs. Robinson’s office.

The posting had gone out across the college for female volunteers to participate in a biology study affecting human sexuality. It was a paid study, so there were many more girls signing up than positions needed, and Mrs. Robinson was able to select only the hottest co-eds on campus.

The more the beautiful girls went in and out, wearing skimpy clothing and flashing some skin, the more I felt my blood simmering. More than once, one of the co-eds would glance at me, startled, then scurry away as if they’d gotten caught checking me out.

This was going to be fun.

Two hot blondes reclined side-by-side on the hospital bed in various states of undress, their bright blue eyes flashing in the fluorescent white lights. One’s hair fell in golden curls, the other sleek and straight. Blouses had to be opened and skirts hiked up to the waist to accommodate the electrodes and other sensors. Mrs. Robinson, clad in a clean white lab coat, used the remote control to adjust the fold in the bed until they were both comfortable.

Gabrielle and I were next door in the observation room, watching the experiment unfold through a large mirrored window and the test equipment monitors. I worried that with me in a separate room, any pheromone scent would be unable to travel to the test subjects. Gabrielle informed me that Mrs. Robinson had already dismissed that concern. My effect transcended normal senses.

Heidi and Isabelle were both members of the Delta Delta Delta Sorority. The Tri- Delt girls were some of the hottest babes on campus, but also notorious bitches. Both ladies were very pretty and they knew it. Even though they were in a closed room with no one else but a female college professor, they flexed their tanned legs and posed prettily to always ensure they looked their best. Both had huge, round breasts, unabashedly fake, barely tucked into expensive bras.

As their brief clothing shifted slightly with their every movement, I found myself becoming very interested in finding out what treasures lay hidden there. This was really going to be fun.

Mrs. Robinson told them to sit back, relax, and close their eyes, which they did obediently. She then left and joined us in the observation room. She set her clipboard down and then stood right behind me, looking into the room just over my shoulder. Then I felt a slight tickle as she brought her hands to my sides, rubbing slightly along my waist while I felt her hot breath against my neck. She had thought of everything.

Just staring at the two girls on the bed would not have been sufficient to make the experiment work. So Mrs. Robinson fell back on the most efficient way of achieving the proper effect. When I felt her hands in my crotch and her lips nibbling at my shoulders, I felt a twitch in my shorts in response. Gabrielle and I kept staring into the examination room the whole time, watching to see if there might be a reaction.

Mrs. Robinson kept up her assault on my willing body, and when she slipped her bare hand underneath my waistband and around my erection, my soft moan was matched by a louder moan from inside the examination room.

Both girls were visibly sweating, panting softly, biting their lower lips and showing all the tell-tale signs of arousal. As Mrs. Robinson kept jerking my rod, I felt the flames inside of me stoking higher while my eyes burned fire at the two blonde babes before my eyes.

Heidi and Isabelle were looking at each other, slightly confused at the feelings washing over their bodies. A girl getting horny talking to me at a social was one thing. A girl getting aroused while sitting on a hospital bed, eyes closed, with electrodes stuck to her skin was a completely different experience.

Heidi, the one with the curly hair, finally just shoved a hand down her skirt and started masturbating furiously, throwing her head back against the bed and moaning loudly. Isabelle was rubbing her own breasts and had a hand in her crotch but outside her skirt. Clearly, my effect induced general arousal, and not necessarily an attraction to me. They couldn’t even see me.

This theory was further evidenced when Isabelle just rolled over and tackled Heidi, and soon the two were exchanging sloppy kisses while trying to pull each other’s clothes off. Most of the electrodes got pulled off as well, leaving faded red circles in their skin where the adhesive had been.

Heidi got to the remote and lowered the bed to a flat position, and then the two of them moved around each other into a sixty-nine position and began to aggressively eat each other out.

Despite my focus on the examination room, my effect was not lost upon Gabrielle. She was panting herself, and had a hand in her own jeans while watching the pornographic scene before us. Mrs. Robinson, by now able to keep her hormones in check around me, motioned Gabrielle to me and moved herself away so she could study and objectively take notes on the events.

I looked away from the window briefly to kiss Gabrielle on the lips, then I moved her body in front of me, molding her against my chest and causing my crotch to press against her back side. One hand moved her jeans aside while I strummed her clit and the other hand snaked beneath her lab coat and under her shirt to cup a firm breast. And then I continued to fondle the slender lab assistant while we all watched the experiment’s success.

Of course, there was still more data to gather. I kept fingering Gabrielle until she had a quiet orgasm. And then Mrs. Robinson was motioning for me to enter the room. I let Gabrielle go, and then followed my professor through the doorway.

The two sorority sisters were still in the throes of their latest climaxes, and barely noticed our entrance. But when I stood next to the bed and started to peel off my clothing, we had their full attention.

Mrs. Robinson had a blood sample gun and calmly took quick blood samples of both girls and then left the room. The blondes submitted calmly and then returned their focus to me, more specifically, to my erection pointing into the air. Our next steps became clear.

Isabelle rolled Heidi onto her back, with legs hanging over the bed and leaving Heidi’s wet crotch at the edge of the bed. Heidi spread her legs in offering, and I stepped between her spread thighs. She cooed at me as I leaned over her and sank my shaft down her tunnel as deep as I could go. She sighed happily as I parted her folds and began to lightly thrust into her, making the globes on her chest wobble enticingly. I propelled my hips against Heidi, and she wrapped her legs around my butt and arched her back, shoving as much of her crotch against me as we moved with an easy rhythm.

Isabelle settled her hips over Heidi’s head while facing back at me, closing her eyes as she felt Heidi’s tongue spearing into her. Then she lowered herself down so she could alternately lick at my rod and the pussy I was splitting open.

The three of us kept up a fast rhythm, and I found that I was already at the edge of cumming after warming up with Mrs. Robinson and Gabrielle earlier. I held back just long enough to give Heidi a muffled orgasm, then with my pride sated, I let loose, filling this beautiful stranger’s quim with my jizz.

When I groaned and pulled myself out, still standing at the foot of the bed, Isabelle crept off of Heidi and reached out to suck on me, eager for her turn. I simply rested my hand on top of her head as she bobbed up and down on me, bringing life back to my rod.

Heidi got to the bed remote again and raised up the back so she could sit up and rest, watching her naked friend blowing me while cupping her own perfectly round tits and feeling my cum oozing out of her.

Once Isabelle was satisfied with my hardness, she turned around and got off the bed before turning and lying forward across the bed, bent forward at the waist. This put her in the perfect position to return the oral favor to Heidi while leaving her ass wriggling back at me.

Heidi simply let her head loll around, enjoying the pleasure as Isabelle lapped at her wet mound, slurping up the combined cum from her box and urging her friend to suckle harder at her clit.

I settled in behind Isabelle, holding her asscheeks in my hands as I lunged forward and speared my new erection into her dripping wetness. I thrust only a few short times before she was quaking with a new climax, her juices trickling out from our joining and dribbling down her leg.

I fucked Isabelle’s pussy for several minutes, enjoying the warmth and wetness. But then I pulled out, and with my hands holding her open to me, I pressed the head of my cock at her other hole. Isabelle lifted her head out from between Heidi’s legs and gasped as the crown popped through her sphincter, and then she moaned as my shaft descended into her ass.

Isabelle raised up her torso while I fucked her ass, bracing her hands on the bed, her arms straight with her head hanging down between her shoulders as she felt me reaming her out. I pressed my chest against her sweaty back, wrapping my arms around her waist while I raised my hands under her heavy breasts which were gyrating with our every motion.

I rested my head on Isabelle’s shoulder, my eyes locked in on Heidi’s gorgeous body while she continued to play with herself and bite on her lip seductively. Isabelle’s pants and screams sounded off in my ears while I plowed up her backside.

Eventually, I lifted Isabelle back until we were both standing fully upright, joined at our hips. Her head lolled back against my chest and I began fucking her furiously while I dropped one hand down into her crotch. She could barely stand, quivering in my arms while I simultaneously titillated her nether regions and violated her asshole.

Isabelle’s whole body began shaking as a powerful orgasm swept through her, dumping a load of her honey onto my hand as her ass muscles clenched tightly around me. Soon after I watched as Heidi, still reclining on the bed, trembled with a fresh climax spreading through her as well.

Finally, Isabelle’s sphincter unclenched and I was able to let loose, bursting a torrent of sperm into her anal chute. I roared out as my orgasm overtook me, and when I was done pumping her body full of cum, I let go of her and she collapsed forwards facedown onto the bed, her asshole still gaping wide and trickling out a little bit of white jizz.

My legs were weak, and I staggered around for a minute before the door to the observation room opened and both Mrs. Robinson and Gabrielle walked in, looking professionally scientific in their white lab coats, clipboards, and composed demeanors.

Heidi let Mrs. Robinson take a new blood sample from her, post-coital. Isabelle was still half-conscious on the bed and offered no resistance as well.

“Thank you both for coming. I hope you enjoyed the experience.” Mrs. Robinson paced the room. “We need to keep you here for one hour of observation and another blood check. But beyond that, if we need anything else further we will let you know.”

Heidi and Isabelle were not the last test subjects. We repeated the procedure with a number of beautiful and willing students: sometimes solo, sometimes not. And after a full battery of tests with dozens of girls, we had a sample size we felt we could trust given our results. The intensity would vary somewhat, but every female was affected by me, 100 percent.

One thing we DID find out was that while every female felt extremely elevated arousal levels, that did not necessarily mean they were attracted to me. In several instances, test subjects would aggressively pursue either Mrs. Robinson or Gabrielle and ignore me completely. Still, even the most hardcore lesbians (pre-exam) would eventually find themselves desperately horny and mate with me if I was the only available option.

All of this testing was physically quite enjoyable for me, but I quickly tired of the experiment routine. Also, after frequent doses of my sperm (whether oral, vaginal, or anal), both Gabrielle and Mrs. Robinson were virtually immune to my effect. Natural, unassisted attraction still led to a few encounters, but for the most part things were back to normal between the three of us.

Also, I had learned to see Mrs. Robinson as the professor, a human being, and no longer the fantasy woman of my dreams. Quite simply, the mystique of “I’m fucking Mrs. Robinson” started to lose its appeal. So I started looking for greener pastures. We had no real connection, nothing in common.

The biological research moved into more of a blood testing and chemistry phase, so we closed the intercourse experiment and my free time was back. Besides, there was still a school to attend. Classes were boring, but my social life increased dramatically.

Our experiments had zero effect on a girl’s memory, and soon dozens of gorgeous co-eds on campus were gossiping about me and the most incredible sex of their entire lives.

It was late on a Wednesday when Heidi dropped by my place. She flipped her peroxide blonde hair and giggled childishly while seductively inviting me to a Tri- Delt party they were having Friday night. It was invitation-only, and I would be one of the very few males present. It was also a lingerie party, so I was to attend ready to strip.

My eyes lit up at the thought of spreading my ?-pheremones throughout a house full of hot scantily-clad sorority chicks, and I agreed easily. That little thought was enough to get Heidi’s blue eyes darkening and her breath into a soft pant, rubbing her thighs together unconsciously, but then she shook out of her reverie and started away down the hall.

Pity, I might’ve gone for a quickie.
