Jen took a look at the pill lying in her hand. “Actually, wait! There's something I want to do first.” She looked at the two girls who became her closest friends many years/about 30 minutes ago. And she wanted to become even closer. Instead of trying to explain her idea she just transmitted her intentions to them via mind link.
Audrey’s face practically began to glow red, while she broke into a massive smile. “J-Jenny, I– You– Yes, YES! I’d love to be part of this!”
Laura's reaction was similar. “Of course I’m in. But can this actually work?”
“You were the ones who pointed it out. It seems like I can at least influence the transformation with my thoughts. When I transformed the principal, I wanted her to become less stuck-up. When I gave you, Audrey, the pill, I was thinking about how everyone seems to be attracted to you. Not to mention, I’ve got some ideas on how to further affect the transformation,” Jen said as she slid down her pants.
“You know me, I love doing things the scientific way,” Laura commented as she started to undress as well. When she turned to Audrey she was surprised to see said girl already completely naked. And judging by the state of her clothes on the ground she might very well have just ripped them straight off. Especially if you consider she still had two tongues stuck in her vagina.
Laura couldn't help but check out the other girl. She was rather small and slightly pudgy with the expected pale complexion of someone who tends to avoid being outdoors. While her B-cup chest was rather modest, her waist made up for that with a generous butt and fitting thighs. Her pussy was shaved clean, probably to accommodate for its attractiveness. A cute face with big, blue eyes and heavy eye bags, that can only be the result of long gaming nights, was framed by long and unkempt black hair.
Once finished, Laura revealed a body that was nearly the exact opposite, fairly tall and with the typical tan of a farm worker (and some freckles). While often described as skinny, especially in regards to her A-cup chest and small waist, she was actually hiding some subtle muscle under her clothes. Also, unlike Audrey, it seems to have been some time since she last shaved her pussy. Her short, blonde hair was kept in a side-ponytail and she decided to keep wearing her thick, round glasses.
Jen’s body was pretty much in the middle between Audrey and Laura in regards to most of her body sizes, the only exception being her C-cup breasts. She had a pretty normal skin tone and kept her body just fit enough to continue being a cheerleader. She had shoulder-length red-brown hair on her head and a small neatly trimmed triangle of short pubic hair in the same color decorated her vagina.
After another moment of appreciating each others’ nude bodies Jen popped in the pill and the girls hugged, rubbing their chests and waists together to create as much skin contact as possible. Getting completely caught up in the pleasure of that act they started to sloppily kiss each other. Jen could feel a tingling starting in her chest and once the other two’s thoughts told her they felt the same, they knew their plan was going to work.
I want us to share everything.
Suddenly a mysterious force turned them around so they were standing back-to-back-to-back in a triangle-formation, their respective shoulders and butts touching. Huge waves of pleasure overcame the girls, causing them to moan throughout the whole ordeal. Jen and Audrey felt their bodies growing or rather being stretched until all three girls were around the same size. They were all pulled backwards and their bodies started to overlap. Jen watched her right side, shoulder, hip and leg, merge with Audrey’s left side, only their arms staying separate. The same happened between Jen’s left side and Laura’s right side, as well as Audrey's right and Laura's left. The flesh of their backs expanded to fill the empty space and the three spines combined into a shared one in the middle of their body, also connecting their nerves in the process. Finally they felt their buttholes connect and fuse into one, which forced their standing body into a permanent sitting position. Jen couldn't remember any transformation being this sexual or arousing to anyone. Maybe it was due to her sensations being multiplied by three, maybe she subconsciously wanted it this way, but as the transformation finished their body was rocked by three orgasms that amplified each other through mind link and shared nerves.
The girls stood there panting for a minute. Once they managed to collect their bearings enough they shuffled over to the nearest mirror, careful not to slide in one of the many puddles they created, to admire their new shared body.
If seen from top-down, their body had a triangular shape with the girls’ torsos being the sides of the triangle. The sides of the girls had merged to create the edges of the triangle. When the sides fused their arms stayed separate and settled over each other, the upper of the two arms at each edge being the respective girl’s right arm, the lower being the left arm of the other. Otherwise their front sides remained unchanged (unless you count Audrey's hair now going fully over her shared shoulders and down her front due to now lacking a proper back). Each of the edges featured only one leg that was a fusion of the respective girls’ legs. At the ankle the legs separated again into two distinct feet that formed a V-shape. Later they’d find out that the legs can freely turn around to allow comfortable walking into any direction. Due to their differing skin tones you could clearly see the seems going down the edges and the legs. On their shared underside was one big shared butthole, right where the skin tone seams met. Due to the fusion of their asses they had to walk with their legs bent, forcing them to present their respective pussies forward.
Jennifer was speechless when seeing their new body. “It’s… wow.”
Audrey was only slightly better at finding words. “I– You– We are beautiful.”
Meanwhile Laura, “Can we please turn around? I want to be flabbergasted, too.”
“Can’t you just watch it through our thoughts and memories?”
“Yeah, I can, but nothing beats seeing the real deal.”
As Laura tried to crank her head to the left, she felt a distinct click in her head. Suddenly the world blurred for a moment and when it stopped she was finally able to see the mirror, as well as felt slightly dizzy. She noticed Jen and Audrey feeling the same and when looking down she made an interesting discovery. Below her head was now the front body of Audrey (B-cup and shaved). Similarly Audrey’s head was now on the shoulders of Jen’s body and Jen got Laura's previous viewpoint towards the wall.
After overcoming the initial confusion and some testing they found out they could freely revolve their heads around an invisible axis to attach them to the different torsos. Further experimentation revealed that their torsos could also revolve around their shared spine completely independent to their heads, which allowed them to somewhat freely pick-and-choose between combinations of head, torso and lower body. Each girl had full control over the torso their head was attached to. While the same was technically also true for the lower bodies, it's much less noticeable due to the control of each leg being shared between two girls anyways. The girls could also all feel sensations from their whole body, though they felt stronger to the girl who originally owned that body part. To Laura's embarrassment they also realized that each head on its own could freely turn 360° to look into any direction and that their necks were flexible enough for the heads to reach each other. Like for kissing, Audrey thought.
After all these revelations about their new shared body Laura convinced them to also immediately test how their first transformations adapted to it. It turned out that Jen could actually cough up pills whenever she wanted and now Audrey and Laura could do the same. Audrey's pussy magnetism was now also shared between all three and could even be turned on and off, though only all at once. When activated all three girls’ tongues would stretch into the pussy that was currently under their head, no matter if it originally was their own or not.
Laura's recursion harmonized with their new body in the most interesting way. Each girl could now produce clones with each torso. The body of a clone was that of the girl who originally owned that chest pre-merge, but it was primarily controlled by the head that was on top of that chest when the clone was created. The clones also inherited all pre-merge abilities of the girls. Audrey couldn't resist creating a bunch of Jens from the C-cups that were currently resting under her head and having them makeout. When it got too crowded in the restroom, Laura also revealed to the other two that she could absorb clones back into her chest. “Do you know how expensive it would be to feed so many mes?”
On the ground they noticed their now changed clothes, designed to cover all three sides of their body at once, looking a bit like a big poncho with arm holes. The pussy area was still free due to the attraction and the only cover for their butthole was a custom stocking for all three legs. Similarly they had custom shoes for their double feet.
Laura offered to decide their body configuration randomly by spinning their heads and then stopping blindly with their tongues, but Audrey insisted on having her tongue inside Jen's pussy for the first day (they promised to try the spinning thing tomorrow). They also gave her Laura's chest. This led to Laura having Jen’s chest and Audrey's vagina and Jen got Audrey's breasts and Laura's pussy.
Once fully clothed Jen asked the others, “Has anyone already looked through our memories to see how we ended up this way in this reality?”
“Shortly after the creation of our mind link we assisted Laura in her attempt to create a cow with multiple udders, which malfunctioned and ended in our merging,” Audrey answered.
Laura just grinned. “Yeah, that sounds like me, alright.”
“It’s interesting how all our changes are simply justified through Laura's experiment,” Audrey commented.
“It's interesting how they still allow her to experiment after all these ‘accidents’,” Jen added.
“Come on, Jenny. I can't remember you ever complaining about our body and even before people already said we three were practically joined at the hip.”
“In your memories maybe,” Jen joked.
Then they ‘faced’ the exit door of the restroom, Jen in front. “Okay, what do we wanna do next?”
