Chapter 1: Studying Tania

Here is the true account of how I discovered the ‘horny drug’ tx34 while researching the effects of hormones on brain function, and why it changed my life - and even human evolution.

I was a Ph.D. student in one of the world’s top neuroscience labs (in the UK), which involved taking brain scans of female volunteers while they performed a variety of tasks, and then correlating these scans with menstrual cycle patterns. I was not quite thirty years old, physically fit and in good shape, just a bit nerdy.

My study was fairly routine research involving several hundred female subjects - statistics mattered in this kind of work. It may have been my daily exposure to these mostly young and attractive female subjects, or it may have been an overflowing libido: I was horny almost all the time, fantasizing about these young girls naked as they went about their tasks.

My gorgeous girlfriend Susan had a bubbly and upbeat temperament along with a fabulous curvy body. She maintained her shape with regular exercise. While we enjoyed long and passionate lovemaking, she was not interested in sex more than a few times a week if that. This meant that many nights I would find myself masturbating to porn on my computer or fantasizing about one of those sexy subjects.

Once at a party, Susan had suggested, only half-jokingly as she pointed to the drunk chicks making out with random guys around them: “Why don’t you screw one of these tramps to satisfy your excessive sexual needs? Just don’t let me ever hear about it.”

She giggled, but I could tell it was a serious message: Go ahead, fuck around if you have to - I don’t care if I don’t know. Aside from a handful of one-night stands with girls in my dorm, I hadn’t taken that liberty.

Most of the time, my only interaction with girls was through my research. One day, a remarkably beautiful teen named Tania was in my lab with her head inside the large magnetic resonance imaging (MRI) scanner.

Such a scanner consists of a huge magnet, the size of a car, with a small chamber in the middle, just big enough for a person. For a brain scan, the person is placed on a table, lying on their back, which is then moved into the magnet until their head is in the center. Anything below the waist is outside the magnet.

My prototype scanner was special in that it had a much higher resolution than those used in medical diagnostics and allowed me to observe changes in brain activation patterns induced by external stimuli.

I knew she was ovulating today thanks to the armbands the subjects wore as part of the study - a fact that made me even more aroused than usual. It didn’t help that her braless tits were visible through the thin fabric of her tight tank top.

Both nipples were hard and protruding from her perky breasts in a display of innocent teenage sexuality. The material of her top was so sheer that I could swear I could see the dark areolas surrounding her pert nipples.

I struggled to control my growing hard-on, but I could not stop staring at Tania’s body, trying to imagine her completely naked. Her head was buried deep inside the machine, giving me the freedom to stare as long as I wanted. As always, I aimed two webcams mounted on my lab computers at the gorgeous girl lying on the table and began recording.

I moved around the lab, lost in my daydream of ramming into her helpless body, while Tania completed the tasks the computer displayed on the VR goggles, she was wearing. Looking at her from the end of the table, I was startled to see that she was wearing nothing but a thin thong under her miniskirt. The small piece of fabric could not hide her shiny and wet pussy.

The string had even been pushed aside. Had she done this on purpose - knowing that she would be lying helplessly in front of me with her head buried in the MRI?

In fact, we even strapped the subjects to the table with their hands tied to the armrests. We did this for their protection because people had sometimes mistaken VR for reality and hurt themselves. I had probably been staring at her dripping wet pussy for an eternity when she suddenly spread her legs even wider and seductively gyrated her hips.

It was clear that this girl was playing with my mind. She obviously enjoyed exposing her young treasures in front of my eyes. Had she guessed that I would be staring at her private parts while she had her head in the big magnet? It wouldn’t have taken a genius to anticipate a guy checking out her hot young body.

Perhaps I should have been more controlled - but my dick overruled my brain. Her glistening teenage pussy was irresistible. My hard cock was out in seconds as my hands began to feverishly jerk off.

Even better, my face got as close to her pussy as possible, almost touching it with my nose. Much too close, as it turned out, as a sudden movement of her legs caught me off guard. I jerked back, but her naked thigh had brushed against my hair.

I instantly froze, realizing that I had been caught. I was racking my brain for a reasonable explanation as to why my head was between her legs when I noticed her hips doing fucking moves. She was rocking her hips up and down in a deliberate, rapid fashion.

There could be no mistake: this was an invitation! My wildest dreams were coming true. Unable to control myself, I pushed her thong aside and sank my dick into her wet teen pussy.

I slid in easily, causing a tremor in her body that made me suspect she had just had an orgasm. I slammed in hard, shaking the table she was strapped to. For ten long minutes I fucked her furiously, making her scream in ecstasy from the magnetic tube around her head, until I released a massive load into her young body.

She was still not satisfied, gyrating her hips, moaning loudly, and begging to be fucked really hard. In one swift motion, I pushed her top up over her wonderfully youthful and perky tits, which still had a prominent cone below the nipples, the characteristic feature of budding teenage girls, indicating their ongoing development.

I fondled her tits, massaged them, and sucked on her puffy nipples. At the same time, I had one hand on her clit, rubbing it, causing her body to squirm in the restraints. She was completely helpless, stretched out completely exposed before me, her wrists and waist strapped to the table with heavy Velcro straps. Watching her adolescent body in a highly aroused state on the verge of release was an intoxicating spectacle.

As she reached the point of no return, her entire body bucked violently against her restraints, her legs trembling and shaking. It was difficult to keep my fingers on her clit with her hips rocking so wildly. The spectacle had made my dick hard again, so I stepped between her legs for another treat of her sweet, young, tight pussy. I slid easily into her cunt, spreading her legs as wide as humanly possible. Her pussy lips were red from the previous pounding and glistening from the sperm that had leaked out.

A stream of cum ran down her ass creek. I applied some to her clit. She let out a delightful moan as my sticky fingers touched her sensitive and tender clit, nestled beautifully against the edge of her smooth pussy. I scooped up more cum and smeared it on her erect nipples. I then blew on those nipples, making them rock hard from the evaporative cooling. I continued to breathe on her clit, making her tremble with excitement.

I continued to play with her small youthful body, getting her more and more aroused until she begged, “Please! Fuck me!!! PLEASE!!!!”

I couldn’t say no and slid my hard pole into her sloppy cunt. Since I had already shot my first load into her, I was much more restrained now and enjoyed the sensation of her soft teenage pussy as I slid in. The previous load was forced back in and lubricated her tight little tunnel.

Her tight teenage vagina pressed so hard against the sides of my shaft that I actually enjoyed the extra lubrication. I was mesmerized by the way my thick cock moved in and out of her body, stretching her pussy obscenely. I could trace the outline of my dick along her belly, watching it stretch her lower body as it was inside her, reaching beyond her belly button.

She moaned softly and gasped as I went deep. When my cock was pushed all the way in, I could feel it hitting the end of her tunnel. I maintained this slow pace for over twenty minutes, periodically flicking her clit or nipples with my finger, eliciting high-pitched cries of pleasure. I could have gone on for hours, enjoying the sensation of her tight little vagina around my dick.

It was getting late, though, and I was beginning to wonder if her mom or dad was waiting for her outside. I didn’t like the idea of getting into trouble, so I slowly started to pick up the pace. Her delicate figure was nearly split in half by the force of my thrusts. She exploded into another orgasm, but that didn’t make me slow down. I kept pumping throughout her eruption and picked up the pace even more afterwards. Her next climax followed almost immediately. I repeated the process, increasing the speed after each orgasm.

She had more than six by the time I felt my cum rising in my balls. I increased the speed of the pounding one last time. Her whole body convulsed. She begged me to stop, which I was unable to do in my highly aroused state.

She alternated between pleading, “STOP! Please, I can’t take it anymore! STOP!” and “Uuuhhh, yes! Oh my God!”

Finally, my release came. I injected another massive round of sticky cum deep into her innocent womb.

After I recovered, I took off her cum soaked thong and put it in my pocket, cleaned her pussy with some tissues, and had her finish the computer tasks. I kept her top off and admired her lovely teen titties, taking some close-ups on my phone. I had already saved the webcam videos to my personal cloud drive and deleted all evidence from the lab computers so that no evidence of my unprofessional behavior would be brought to my supervisor’s attention.

The footage would make for a great jerk-off session, I thought.

When Tania had completed her tasks, I released her from the restraints. She came out of the MRI scanner with a big grin on her face. She asked me if she had completed all her tasks to my complete satisfaction. I replied that I was very pleased with her performance today and looked forward to seeing her next week.

Despite her youth, she was already quite a sexy little vixen, I observed - her outfit a blatant demonstration of her advanced plan to seduce me, a man almost twice her age. Who could resist such temptation, I tried to rationalize, this act of cheating on my girlfriend - and besides, Susan would never know, what could be the harm?

As she danced around the room, Tania flashed her tits at me a few more times. She even scooped some cum out of her pussy, rubbed it on her tits and smiled at me. She confessed how much she had fancied me all along, how much she liked older guys. I was apparently the youngest she had ever slept with! She admitted to regularly screwing two teachers at her school, one of whom was about to retire, and all of her mother’s various partners.

She kept trying to get me horny again, but my balls were completely drained. She finally gave up and started to leave. As she was about to open the exit door, she turned around and surprised me with an attack on my mouth, French kissing me until we were both gasping for breath.

“Only hookers fuck without kissing,” was her shockingly mature explanation before she turned and headed for the door, humming with youthful vitality, “See you next week! I’m not on the pill, you know,” she giggled before walking out, leaving me wondering if I was ready for babies.

Was she mature enough for children, being practically a child herself, not much more than half my age? My mind drifted back to the fact that she was ovulating today - the worst time in her cycle to fuck unprotected! I made a mental note to pack some condoms for the lab just in case she wanted a repeat performance next month.

When she returned the following week, I made a point of seeing her in person in the waiting room. I was scared to death that this horny teenager might get pregnant, which would have the potential to derail both of our lives.

She was with her mother, an attractive woman no more than ten years my senior. She was nursing her baby, her left breast fully exposed. I cleared my throat to introduce myself.

She looked at me happily, not at all bothered by her exposed breast, and greeted me with a big smile.

“Oh, Tania is so excited to be a part of this wonderful project!” She turned to her daughter and said, “Keep your hands off that handsome boy, will you?”

Tania replied, rolling her eyes, “Mom, I’m no baby no more!”

She jumped up and made a show of hugging me tightly with exaggerated affection, her youthful body pressed fully against mine, rubbing against my growing erection. All the while, I stared at her mother’s exposed breast as if in a trance.

“Don’t wait for me, Mom!” she yelled over her shoulder as we walked toward the lab, taking my hand in hers.

It was now her mother who rolled her eyes mockingly and replied, “Okay, sweetie! Have fun, you two!” She kept her eyes on my crotch, which was bulging from my hard-on, and unconsciously liked her lips.

I was still wondering if her mother had just given her the explicit green light to screw me when Tania held a white plastic bar in front of my face.

“Baby didn’t work out,” she giggled, waving the pregnancy test so close I could barely focus on it.

“You wouldn’t believe how good it feels when they suckle your nipples,” she cooed.

“Oh, I wish I had some milk in here,” she continued her baby fantasy, squeezing her boobs hard.

Was she toying with me, or was she serious about wanting a baby? I wasn’t against starting a family, but she was way (!!) too young to be a mother!

I couldn’t think about babies for much longer as she took off her long dress in one swift motion, revealing her topless body.

“Oh, I guess that might spoil the fun,” she said, tossing her dress aside. Once again, she hadn’t bothered to put on a bra.

Her youthful, perky breasts with their puffy nipples needed no support, but a little more concealment would have made things a lot easier for the male half of the population.

Smirking, she slipped out of her flimsy panties and tossed them over her dress: “Wouldn’t want them in the way either.”

Showing off her tantalizing body, she turned and put on a show, bending over with straight legs to undo her shoes. I watched open-mouthed as she lay down on the table and made a show of putting a finger in her wet pussy and licking it clean before disappearing into the tunnel of the big magnet.

She spread her legs wide, lifted them up in a V-shape, then moved them down until she performed a complete split. Her youthful pussy was exposed in a delightfully erotic display of youthful fertility. I shook my head to come out of my trance and stepped forward to secure her arms and torso to the table.

I took the liberty of brushing against her hard nipples, making her moan with pleasure inside the magnet. I made sure to record everything by turning on both the video cameras and the MRI machine before stepping back to admire her alluring body.

Despite her inviting demeanor, I hesitated to take her helpless teenage body right away. However, I couldn’t resist caressing her body with my hands. She moaned whenever I touched her puffy titties, and even more when I finally made my way to her pussy, which seemed to attract me like a magnet. It was perfectly smooth and surprisingly warm. As I got closer, I could sense that she must have taken a bath just before her visit, as she still smelled of body lotion.

When I caught a whiff of the sweet aroma of moisture in her pussy, I couldn’t resist putting a finger inside. She let out a moan of approval as she bucked her hips to connect with my finger. She kept gyrating her hips as if trying to get herself off on my finger. I couldn’t hold back any longer and dropped my mouth to her clit, sucking and licking around the tiny pink knob.

Her moans grew louder, her hands clenched tightly on the armrest, until she erupted in an orgasm that made her body twist and shake. I had to use all my strength to keep her hips pinned to the table so that my mouth stayed connected to her clit.

Eventually she calmed down and let me continue my oral stimulation. It was only after her third orgasm that she screamed: “FUCK ME!!!” from inside the magnet and begged me to come inside her.
