Futaba tapped her fingers on her legs while all the scientists were behind the one way mirror, getting things ready for the tests she was about to go through. She had a lot of fun using the store bought transformations and saw that they would allow you to test some of their newer serums and they would pay the testers for it, that’s why Futaba was here. A speaker flared to life as the scientists began speaking into the mic.
“We just have a couple precautions before we begin. You are Futaba Sakura, correct?” They began. Futaba answered with a nod. “You understand that we will be changing your physical form and putting experimental serums to the test?” Another nod came from the redhead. “We will be able to change you back if anything goes wrong anyway, final question. You are okay with any change we give even if it changes your gender, species, age, or is sexual in nature?”
Futaba faltered for a second before responding, “I’m alright. Let’s do this!” She said, standing up.
The staff went silent again before speaking up again. “Alright, for this first serum. Is there any hair color you’d like to see on yourself?
Futaba thought to herself for a second before responding, “Platinum Blonde, my friend’s hair is that color and I wanna see how it looks.” She said to the staff.
A couple seconds passed before they slipped out a vial with a platinum blonde serum and a very skimpy bikini. Futaba picked it up and held it at a distance. “Excuse me but what the hell is this!?!” She asked, a little distraught.
The microphone flared back to life with the voice of a staff member. “ Your current attire will makes changing into your first form very difficult. That is to give yourself as little restriction to the growing process. Don’t worry, only medical professionals will see you in it. You can slide us your clothes and we’ll hold onto them.”
Futaba hesitated but slowly took off her clothes and swapped them with the bikini. She tied it off, with a little trouble, in a way that when her body grew, the bikini would still stay on. She took the vial and drank down the contents. She set down the vial as her orange hair began to dull to a platinum blonde. A piercing headache rang through Futaba’s head as she began to grow taller, her budding chest starting to rise with each breath along with her lower curves. All her computer knowledge began to fade away, only leaving her being able to operate a phone. The tiny bikini began to strain against her now massive chest, which was nearly as large as her head. “Like, now I’m totally hotter than the other girls… wait. Did I, like, talk like this before?” Futaba wondered aloud. Her hips, thighs, and ass had swelled up considerably as the bikini’s string strained. Futaba finally caught a glimpse of herself in the one way mirror. “Damn, I like totally look hot! There’s no way Ren can resist me now.” She said, feeling her new form. She kept trying to get a better look at herself but kept getting blocked by her hair. On the table in front of the one way mirror were different items that might come in handy, in this case she picked up two scrunchies. She quickly put her hair up into two ponytails, which she couldn’t do on her own before, unintentionally making her look like Ann. “That’s totally better!” She said, going back to her reflection. She couldn’t hear it but the staff was busy writing notes as she kept checking out her body.
Futaba’s intelligence began to return as her body shrank back to it’s normal proportions. She felt meek, watching her body shrink back to normal. The bikini nearly slipped off before she tightened it back to her normal form. “Should I keep this on?” She asked to the mirror.
“Yes, it helps because that can easily snap off if need be.” A staff member responding before putting through another vial with an orange serum in it this time. “This time we took the color from your normal hair color. We believe you’ll enjoy this one.” They said before shutting off the microphone. Futaba took it and drank it down.
Futaba’s whole body began to pulse with strength as she began to grow taller. Her small chest began to shrink back into her body as her shoulders began to broaden out. A heat encased Futaba’s entire body, sweat dripping down her less and less feminine body. Futaba was surprised with the newfound strength filling her body after being so used to being small and weak. Her train of thought derailed as her crotch began to warm up and something began pushing at the bottom piece of her bikini. Her hand hesitated around the string of the bikini before unteing it. The bikini bottom fell away to reveal Futaba’s privates changing. Her clit was pushing itself out and forming into penis, her ovaries had pushed out and were currently swelling into testicles while her vagina sealed itself up. Futaba reached down to feel it when something on his arm caught his eye. Orange scales were beginning to push out of his body. He took his eyes away from his scales and noticed that he was almost as big as the room he was in. Futaba got down onto all fours which felt natural as his scales overtook skin. His nails began to sharpen into razor sharp talons while two large bulges began to form on his back. Futaba’s neck began to extend while his face began to morph into a strong muzzle. The bulges on his back grew into wings as Futaba finally filled the room as a large dragon. The staff had moved to the upper observation deck as if they stayed, all they’d be able to see would be Futaba’s large dragon cock. They took their notes and moved back into the original room as Futaba shrank down to her normal size. Before she was completely changed back, she was able to feel what her cock felt like before it returned to being a clit.
“So these next ones are based around video games, we selected them because in your application you stated that you liked them.” The staff said pushing through another vial, this time containing a color that Futaba couldn’t really put a finger on. She shrugged and drank the contents as usual. Futaba began to grow again, this time in size and heft. Fat began to fill her body as she grew taller, her breasts rose along with her small gut. When her body seem equally rounded out, her breasts kept growing while her hair began to grow out. She cupped her hands around her blooming breast that kept growing while jewels and plant life adorned her body. Her hair had gotten so long it piled up on the floor before being tied up into a large updo adorned with jewels to keep it in place. Futaba began to float off the ground when her breasts finally stopped growing, she let out a hearty laugh and floated for the staff to observe. They jotted down notes and let her return to normal.
“Man, being a great fairy was so cool! That body and all those jewels were awesome!” She said, notably excited. The next vial had a pink liquid with black spots in it. The staff didn’t say anything this time around, which confused Futaba but she drank down the serum. The feeling of change enveloped Futaba as something began poking through her hairline. Two horns poked through her hair that was currently falling out. Her ears began to elongate and moved to the top of her head. Her skin began to turn to a pink hue while her mouth grew out into a small snout. Futaba started shrinking down as fat began to fill her body. Her fingers merged into two small tips that hardened into hooves. Her stomach turned tan when four very large teats grew out of her new udder. Her feet became hooves while a long tail grew out, completing her transformation into a Miltank. The floor under Futaba seemed to be getting wet, causing her to look down. Coming out of her new udders was milk, and a lot of it. Futaba began to panic which caused her to grow more teats and starts spewing more milk. “What the hell is this?!?” Futaba said, panicking.
“Don’t worry, this is all a part of the tests.” A staff member answered quickly.
“Well, I don’t want this! I’m done!” Miltank Futaba said, waddling towards the door. She didn’t make it far before a dart was launched into her. A serum was injected into her body, causing her to change again. Orange fur started covering her growing body, curly orange hair growing out of where her mane would be. Her snout grew a little bigger with a giant pair of lips adorning the end of them as she gained more heft. Her udder began to disappear as a large bull cock replaced it. Futaba shuddered to a stop. “What did you do to me!?!”
“You agreed to five transformations. You signed contracts and will not be able to leave until you complete your testing.” The staff said
“What if I say no?” Futaba said, trying to test their bluff. Another dart hit him, this time making his balls start to grow. His dick was growing as well, nearly as long as his whole body, but not as much as his balls. They were so big that his back hooves were off the ground and Futaba was laying on them. “...alright. I’ll finish the tests. He said meekly.
The staff shot a third dart into Futaba, this time changing her back to normal. “Don’t worry, this is the last test we have for you. After this, you can go home with your pay.” They said, pushing through a vial with a peach colored serum. Futaba took the vial and drank it instantly, wanting to get this over with.
Futaba felt her stomach begin to gurgle as fat began to fill her body once again. Her hair began to clump up and stick together as an odor began to rise off of Futaba. Her armpit hair and pubic hair began to grow and get very bushy. Her body had fattened up immensely, her breast were very large and were lying on her large stomach. Her hips and thighs were massive and she had a very big ass at that point. Sweat began dripping down Futaba’s flabby body as she wiped her brow with her meaty arm. “I guess this is what I’d look like if all that junk food kept up with me.” She said jokingly before letting out a huge burp. “Sorry, I don’t know where- URRP” She said before another large burp pushed its way out of her mouth. A blush covered her face when her stomach gurgling again. She gained another hundred pounds, rippling out among her body. “I grew again?!? I’m so fat now.” She said to herself when she let out a large fart. “I’m sor-” was all Futaba got out before another large fart escaped her. Another embarrassed blush crossed her face causing her to grow again. “God, this is how Haru would look is she only ate from Big Bang Burger!” Futaba thought to herself before she felt her body start changing again. Her hair began to fall out and turned auburn when it reached a length around her chin. Her face rearranged itself while fat filled her cheeks and neck. Her boobs also grew in size a little more before the changes stopped. “W...why do I look like Haru?!?” Futaba screamed in confusion., which caused her to grow even more. She was so heavy at this point, she couldn’t hold herself up anymore and couldn’t move.
A couple scientists rushed into the room and started strapping medical equipment to her flab filled arms. “Ms.Sakura, do you feel alright?” One of them asked.
“Besides being over a thousand pounds, yes. What happened?” She asked, trying to stay calm.
“We don’t know, you were supposed to still look like yourself. You shouldn’t look like whoever you look like now.” One of them said, drawing some blood from her. “You’re gonna need to stay a couple of days so we can monitor you.
Futaba panicked for a second which caused her to grow again. “...Alright. Please just help me.”
-------------------------------------------------------------------------------------
Ann, Makoto, and Haru stepped into the small viewing room. A staff member stood next to the closed off window. “Thank you for coming to see Ms.Sakura, now I will warn you that she does look different,” He began, trying not to lock eyes with Haru. “She’s getting better and should be home within a week. Are you ready?” He asked.
The girls nodded and the man flipped the switch, lowering the blocker in front of the glass. All three of them gasped as Futaba was revealed, sitting down in front of the glass with Haru’s exact face.
“Futaba! What happened?” Ann said, getting close to the mirror.
“Are you alright? Makoto asked.
Haru said nothing as she was transfixed with the fat and slobby version of herself in front of her.
“Did those transformations hurt?” Ann asked.
“No, they were actually kinda fun while they lasted. I wouldn’t mind doing it again, once I’ve gotten out of here for a while.” She said.
Haru was about to ask her something when a staff member walked into Futaba’s room. “Alright, we figured out a possible solution. This spray here,” the staff member began while holding up a large aerosol can, ” will change you into a bull which should reduce the changing back time.”
Futaba nodded eagerly, “even if it won’t be shorter I’ll be able to move again, let’s do it!” She said.
The staff member began spraying the serum onto Futaba’s large body. Slowly her fat began to shrink back into her body while her face began to push out into a snout. Her hands and feet shifted to hard hooves as her genitals swapped in front of her friends. Pink fur covered her body while her hair, which still looked like Haru’s settled in where her mane would be.
Haru and Makoto were transfixed on the changing bull that they didn’t notice Ann trying to wipe something off of herself. The scientist that had sprayed Futaba noticed Ann rubbing off the liquid and the dripping liquid around the holes in the glass barrier. “Ms.Okmura and Ms.Nijima, you may want to step out of that room.” The two girls turned to see Ann, her face beginning to morph into a bull snout and her body trying to escape the confines of her clothes. The two girls got out just before there was no room left as Ann had now taken up most of it.
“Ann. Are you okay?” Haru asked.
“Physically, yes. Otherwise I’m a bull!!” She said angrily, stomping her hoof.
The scientist lowered the separation wall and brought Ann into the same room as Futaba. “We’ll alert Ms.Takamaki’s family about the mishap. Please take your leave as we don’t want any other mistakes.” The scientist said to the two remaining girls.
Haru and Makoto left, leaving Ann and Futaba alone. “At least we can stick it out together.” Futaba said with a slight smile.
“Yeah, those this dick is gonna take some getting used too.” Ann replied, brushing it with his tail.
