It had now been a full month since Henrietta Jekyll had happened upon her version of her ancestor's formula. The purple concoction had been the source of much enjoyment for her and roommate, Anna, with both of them now engaging in many sexual misadventures and further discoveries as their alter egos, Heidi and Sonya. They'd turned four more girls into sexually ravenous Amazons such as themselves and Henrietta had also discovered the effects of the Formula on men through her professor accidentally taking a large dose of it and becoming a hulking alpha lover with some very surprising side effects: bodily secretions that functioned as a powerful aphrodisiac for women around him.
Henrietta hadn't really investigated if she possessed these in her Heidi form but was beginning to get very excited about the possibilities with them. She had noticed that Heidi and the other Amazons emitted a powerful pheromone that seemed to affect men around them but she hadn't noticed any reaction to fluids or secretions. The pheromones had basically just drawn men nearby into aggressive lust and she wondered what would happen if she'd pushed that even further.
After two long nights in the lab, she'd cultivated another revised version of the Formula. The usual purple hue of the liquid was now startling light blue. She looked at her secure refrigerated vault with her backup supply in the standard form and felt confident that if there were any issues with this new batch, she would have ample reserves to fall back on. She poured her new blue version into four water bottles and placed one in her purse. She wanted to run multiple tests so she'd need more for later. She then checked her backpack and made sure she had a few changes of clothes since Heidi was prone to basically bursting out of Henrietta's outfits and leaving her with nothing to wear when she'd eventually change back. Currently she was wearing a conservative outfit of a pencil skirt and a red polo top with her lab coat over it. She looked herself over in one of the mirrored walls and shrugged. Her normal form wasn't much to look at. It's why she had become so enamored with becoming Heidi and experiencing life and pleasures as her. Sometimes she wondered where she stopped and Heidi began... if that personality had been her repressed longings, held at bay by a lack of confidence and fear. Whatever the nature of it, the results were the same: she relished everything about her liberated alternate self and so did Anna and the other girls.
Dr. Nolan, her faculty adviser who had taken the Formula by accident, had seemed wracked with guilt afterwards. He had apologized to both Henrietta and Anna after he'd finally changed back to normal (four marathon love-making sessions with the both of them later) and had complimented Henrietta on her accomplishments. However, he had encouraged her to be wary. "Other people might find this discovery as a means to corruption. Guard it and be watchful." He'd also promised her that her thesis grade was secure since he'd seen just what her discovery could do firsthand. "I'll help you write up the report myself" he'd promised. She had asked if he wanted any of the Formula for himself and while she'd noticed hesitation in his eyes, he'd eventually held fast. "No. I'm fine with just being myself for now. But I'd be lying if I said I didn't enjoy a respite as that... Thing."
Henrietta shrugged off the memories. It had been an enjoyable Friday night but now she was living in the current goal: testing out her Blue Formula. She took a deep breath and poured the contents of the bottle down her throat. The taste was similar to the purple version but had a slightly sweeter aftertaste. She moaned about as she finished the bottle off and then licked her lips. She was excited for what her experiment could produce tonight.
Grabbing her backpack, Henrietta was about to lock up when she heard a sudden thud. She looked up and didn't see anyone elsewhere in the lab. "Must be on a different floor, " she thought and gathered her backpack and her other bottles of the Formula (one more of the new batch and some of the old for Anna and herself).
The hallway of the science building was only slightly populated this evening with some students already having left for fall break. The campus would only be sparsely populated this weekend which was in part a relief and a disappointment to Henrietta. A relief since there would be less chance of discovery should Heidi and the others be unleashed on a willing populace but also disappointment because if they were, the pickings might be slim. She racked her brain to think of a proper place to try out her new creation as she walked through the halls and out into the evening. As Henrietta strolled, she reflected on more possibilities for her creation and if there was a way to make Anna permanently into Sonya. It was obvious she enjoyed being her more while Henrietta was fine with having both sides of her life. The other girls had started to treat further doses as more of a recreational activity than an addiction but Anna... she was so said being herself and would sleep for almost a full day when she'd change back. Henrietta made a note of this for later as she had finally found a possible destination: the campus gym. An evil smile crept across her face as she put a plan together.
First, Henrietta went to the locker room securely stored her bag in a locker. She also took off her lab coat and hung it up. She wouldn't, however be needing to change out of her clothes. She looked around and saw one or two other girls showering and changing. They were all very attractive to her pre-Heidi libido and she was starting to feel her breathing hasten. Like before with Dr. Nolan, she focused and tried to keep the change in check so as to complete her plan.
She sat, patiently on one of the benches watching as more and more of the girls were changing into their gym clothes, but more importantly, she eyed the sauna door off to the side of the locker room. She counted almost five girls in there now, all with towels wrapped around them and conversing about trivial topics. A smile crossed her lips as she finally couldn't take it anymore. She was ready for the next phase of her plan. With that release of her self-control, she let her body complete its foremost desire and the changes were upon her in minutes. Heidi's larger, stronger body tore through hers and pushed the pencil skirt apart into an almost loin cloth. Her larger breasts pushed against the polo and Heidi's stronger hands pulled the cheap cotton apart at the front creating a cleavage and midriff revealing top. As the Amazon shook her head, Henrietta's bun cascaded apart from a blond knot into a mane of dark brown hair. Heidi stood up and slid off the now soaked and stretched underwear Henrietta had forgotten to remove. She also kicked off her heels and took a long stretch, enjoying being out of her "cage" once more.
"Now," she smiled fiendishly. "Let's see how much fun we can have."
She inhaled deeply and could smell her new musky scent coming off her body. It was a thick aroma that was more of a pleasing smell than body odor but still as pungent and permeating her surroundings. Her body was also dripping with sweat and droplets were running down her enlarged cleavage as well as her long legs. Among those droplets of sweat were also drops of vaginal secretions that were about what you'd expect from an aroused creature like Heidi. She took one of her long fingers and ran it up her inner thigh, taking a taste. It was sweet and almost like citrus.
With a confident stride, Heidi strolled towards the sauna door and opened it. The inside was a dim room with wooden paneling along the walls as well as wooden benches around the perimeter. In the center was a long double wooden bench where patrons could sit almost back to back if they'd wanted. Steam and moisture hung in the air and it was almost twice as humid as the locker room. This would do perfectly.
None of the girls noticed Heidi enter and then close the door behind her. She examined all five of the girls like prey and bit her lower lip examining their young forms, hidden semi-securely under white cotton towels. Each girl looked half asleep enjoying their sweating and relaxation. A young blonde girl in the corner was the first to notice Heidi after sniffing the air for a few seconds and then opening her eyes and looking around, settling on the stranger and her disheveled appearance. The young girl had short hair in a bob and looked longingly towards Heidi. There was no registering of shock or confusion, just hunger and lust as she drank in the smells and pheromones coming off of Heidi's body. The bob girl stood and walked across the floor, her legs slightly shaking with each step. Her towel started to become unfastened but she didn't seem to notice. As she walked towards Heidi, her balance gave way and she lowered herself to her knees. Heidi approached her and dipped two fingers into her own pussy, getting her hand good and sticky with juices. She ran them across the girls lips and watched for the results. The bob girl gasped started masturbating furiously, plunging fingers inside her wet pussy and running a hand over her sweaty chest. Her will was completely gone and the only thing she seemed focused on was pleasure as her eyes followed Heidi around the room.
The noises the bob girl started to make alerted the other girls in the sauna and they began to look around, slightly confused until the aroma hit them as well. One black girl leaned back against the wall she was sitting at and stared in still wonder at Heidi. This was Heidi's next subject and the Amazon leaned in and took the girls chin in her sticky finger. "Go on... lick my neck, my dear..." and the black girl complied, taking a long taste of the perspiration that was coming of Heidi's neck. Heidi rewarded the girl with a taste of her fingers as well and the girl took the resulting juices in like the first taste of water she'd after a week in the desert. Using her fingers as bait, she drew the black girl up off the bench and towards the bob girl on the floor. She covered her pussy in more juices and rubbed them over both girls lips and watched as they hungrily licked sweet secretions off of each other lips.
