The blue lighted faded away from around Saber, revealing where she had been summoned to. Her heart swelled with excitement, but her face remained stoic to hide her excitement. She was back in the potion room. “Hello Master, I suppose you have more potions for me to test?” She said.
“Yes I do, only five this time and here’s the first one.” The voice said, getting straight to work. A blood red potion slid out of a compartment, which Saber quickly picked up and drank down. She slid the potion back in as her muscles started tensing up, reminding Saber of the previous potions she tested. Her skin started turning red as her clothes began to tighten on her, her hair growing longer as it freed itself from the ribbon holding it. Her armor began to fall as her muscles became to big and stretched out the leather straps holding the armor to her body. Saber started to grind her teeth which unbeknownst to her were sharpening into fangs. Large yellow horns poked their way out of her hairline as her hair cascaded down her back. A loud ripping noise filled the room as her muscles became too big for her clothes making them fall off her body, all except her panties which still clung between her large muscled legs. Saber’s breasts had grown alongside her height, she soon reached a height of nine feet which caused her horns to start scraping the ceiling of the room. Saber reached up and fondled her large breasts when they started to shrink, her shoulders broadening out as they did. Saber’s clitours began to grow outward, her panties beginning to stretch outward. Her ovaries began to migrate out of her body, morphing into testicles as they made their exit. When they exited her body, they began to grow in size and hang down causing her panties to stretch even more. Soon, Saber’s new dick reached an impressive four feet in length, causing her panties to snap and fling forward into the wall. Saber let out a few grunts as he wrapped his hand around his cock.
“I probably should’ve told you to take your clothes off first… but where’s the fun in that.” The voice said to the Oni.
-----------------------------------------------------------------------------------------------
Saber drank down some water after turning back to normal, she needed to hydrate after going nuts with her cock. “What’s next master?” She asked, watching another potion slide through the compartment. She picked it up and drank its contents without a second guess. She put the beaker down as her hands began to go numb along with her mouth. She looked down at her hands, watching them turn black and merge into hooves until her mouth blocked her view. Her teeth began to get thicker as her nose and mouth connected to form a snout. Her hair fell out leaving only a long blonde mane in its absence while white fur covered Saber’s body. Her body began to fill out into the appropriate size for a horse, her arms getting bigger while her feet shifted to hooves while a long blonde tail covered her asshole. Saber looked at her body and tried to speak but only able to let out a whine.
“What can I say, a knight needs a steed.” The voice says with a chuckle.
Saber let out another whine and stomped her hooves.
“Hey! Don’t be like that, I’m your master and you’ll accept that you’re a horse right now. Here, I’ll make it so you can enjoy it.” He said, making a gas spray into horse Saber’s face.
Her genitals began to change as a decent sized equine penis grew out while her balls dangled between his legs. Saber whined again.
“Bigger? I mean sure, but it won’t do you any good.” The voice replied with another spray to the face. His cock began to shoot forward, dripping with precum and quickly poked between his front legs. Saber let out another whine, so close to a climax.
“One last should do the- Oh shit! That one was for a bull!” The voice said with panic as gas sprayed Saber in face.
Horns sprouted from Saber’s forehead as his snout changed to a shorter and more square one, his stomach began to bulge out with the weight of a bull as his cock surged forward reaching an insane twenty feet length. Saber let out a large moo as he came, shooting his seed all over the wall in front of him. His snout began to shrink, returning to a human form as the effects were wearing off due to two serums not mixing well. “I’m… one sexy… bull,” was the last thing Saber said before passing out, her form starting to revert as he laid there.
----------------------------------------------------------------------------------------------
Saber woke up after taking a good long rest, she lifted her head and stared at the cumstain she created on the wall. “Damn, that’s a big stain.” Saber thought to herself as she lifted herself off the ground. Saber turned around to face an outfit fit for a geisha.
“I’d like for you to put that on before we get started with the next potion Saber.” The voice replied.
Saber started unwrapping the bands around the center of the outfit and slowly put it on, it was a bit loose on her but she figured that was about to change. A potion slid through the compartment and Saber walked slowly over to drink it, not wanting to mess up her outfit. She drank the potion in one go, setting the glass back in the compartment. A mirror flipped so Saber could watch as her blonde hair began to grow longer, turning black as night while it lengthened. Her hair started tying itself back into three long buns with flowers and combs in it. Snow white makeup covered her face with bright red lipstick adorning her beautiful lips. Saber then felt a heat begin to rise in her chest. Her heart beat sounder louder as each beat caused her breasts to rise. Loud heart beats bounced in her head as her breasts grew out of control and hung past her waist. Surprisingly, her outfit contained the massive mounds inside it. Another heat rose inside of Saber, a heat that stirred within her loins. Her breath became hitched as thoughts of lewd acts filled her mind. She felt the telltale signs of her arousal trickling down her legs as she sat down and tried to keep her composure. She heard the sounds of a compartment opening up to reveal a man with a mask and a certainly above average bulge in his pants. Saber licked her lips and said, “Please, come sit with me.” A devilish smile on her face.
----------------------------------------------------------------------------------------------
The door slid shut just as Saber started to turn back, covered in many fluids. Saber watched as the room changed again, revealing the same patch of dirt she had became a tree in. The patch was larger and could support a much larger tree. “Am I becoming a tree again?” She asked the voice.
“Yes but I’ve made some changes to the serum so it’ll be different.” The voice replied, sending the potion her way. Saber picked up the potion and spilled it on herself as she stepped into the dirt patch once again. Her feet, which had turned to roots, dug down and instantly found an underground pool of water. Her legs flared out into a large trunk as sap began to be produced within her body. Her belly began to swell with all the sap her body was making as a bulge started growing out from her crotch. As bark covered her vagina causing sap to trickle out, her dick returned and much larger and thicker than before. Two more adjacent cocks joined the original, though a little smaller than the first one. Saber’s stomach was fit to burst, looking as if she was pregnant with eight, while her breasts sat comfortably and leaked sap across her stomach. Saber raised up her arms, branches starting to grow from them.Leaves sprouted on them as well, causing a euphoric feeling to start building up. Saber’s mouth opened up to her surprise, a tourent of sap starting to flow up and out of it. Her transformation was nearly complete as she felt her orgasm building up and her head starting to bulge. After a minute of being denied a climax, her hair morph into leaves and connected to her branches. This gave her a massive afro made of leaves and made her spew so much sap in response. Light shone on Saber as her thoughts drifted away from here.
----------------------------------------------------------------------------------------------
The bark around Saber crumbled as she crawled out of the stump that was her body. She found that the main floor was now a large pool surrounded by a large flower. “This last potion needs a conductor, hop on in when you’re ready.” The voice explained.
Saber plugged her nose and jumped in, her whole body being coated in the transformative serum. Her body began to rapidly expand within the pool, a cock growing out from her body as weight swelled inside her. Her hair grew out while heavy makeup applied itself all over her rapidly changing face. Saber felt her lips increase in size, becoming very plump and juicy. Her nose stretched out so far that she didn’t need to go cross eyed to see it. Saber’s bust also increased with her growing body which soon were covered with leaves that had fallen into her pool. Once Saber reached an enormous size, she swam towards the surface and let her new great fairy body be shown, her cock lying on the edge of the pool.
“Now don’t you look beautiful.” The voice said, turning away from the screen they were watching when they heard a laugh close to the one an actual great fairy had. They turned to find that Saber was still growing, so much that she had broken the great fairy pool. “Oh no! I need to change you back!” They said, messing with vials of serums. The voice suddenly heard a loud noise causing them to turn back to the screen. Saber had grown so large that she broke through the wall. Even worse was the fact that the wall she broke housed the Bull transformation gas, causing it to flood the room. Saber’s plump lips soon formed into a large bull snout as horns poked through her hair. Her breasts started to fade as her cock took on a more bovine look and her female sex sealed up. His hands rapidly lost its feminie looks at they morphed into bull hooves, the same happening to his feet. His gut lost any sense of beautiful body weight as it became pure beef fat. Saber began to moo loudly as his cock unleashed a tidal wave of cum. Saber shrunk down to his original size, clearly still a bull with two more cocks then he originally had and even more growing rapidly. A blue light enveloped Saber, causing him to vanish from the sea of cum, the summoning finally over.
The voice sat down and let out a large sigh. “That’s gonna be one hell of a mess to clean up… but not as much as Saber will, trying to explain why she was a bull.”
----------------------------------------------------------------------------------------------
Saber, still passed out, materialized in a field near his home. Saber thankfully looked like a normal bull so he could blend in… until somebody notices the twenty cocks he had.
