It was an ordinary Saturday in Porkbelly, the sun was shining, birds were chirping, and a certain ten year old was laying across his bed.
"Ugh..Dukey...so...bored..." The boy said talking to his dog.
The dog, whome the boy had addressed, looked up from the morning paper and took a sip of his coffee. "You know Johnny, you could see what your sisters are up to in the lab. It is only 8am, this is early for you since you normally sleep until noon so it will catch them off guard."
Johnny jumped up from the bed suddenly filled the energy. "Sounds good to me, Susan and Mary will be shocked, let's go dog!" He ran to the space between his nightstand and dresser and slid a secret panel on the wall. When the panel moved it revealed a button, which he pressed already looking forward to finally getting one over on the girls. The button triggered a mechanism that moved the cabinet the television was on and there was two tubes in the new space. Johnny got in one and Dukey, once he was done with his morning cup of joe, jumped in the other. A few seconds later they were in the lab where he spotted his sisters watching something on the large monitor.
"Hey my genius sisters, whatcha watching?" Johnny said as he walked up behind them. His sisters, who's names were Susan and Mary, nearly jumped out of their skin as Mary changed the channel.
"N-no-nothing Johnny..." Susan stammered as her and Mary spun around, when they did, Johnny started snickering at what they were wearing. Mary was wearing a purple shirt with a yellow pony with a pink mane and tail surrounded by birds. Susan was wearing a green shirt with a white unicorn that had a purple mane and tail and was surrounded by diamonds.
"Is...is tha-...is that what I think it is?" Johnny said between outbursts of laughter. "You..you two watch My Little Pony!?"
Dukey deadpanned and ignored Johnny as he flipped back to the show, then shook his head when he looked at the girls. "Fluttershy and Rarity...really you two? Everyone knows Applejack is best pony."
Silence filled the room as Johnny's, Susan's, and Mary's mouths all dropped in shock. "YOU ARE A BRONY?!" They exclaimed in unison, the vibration from the shout nearly breaking the window.
"Eeyup, I am sugarcube." Dukey said in an Applejack-like manor, "have been fo' awhile now, and aft'ah all, she has a pet dog."
"That doesn't make her best pony, keep in mind Fluttershy trends to all the forest animals." Mary said fuming.
"Oh come on, Rarity knows the finer tastes like fashion." Susan added, this sparked an hour long fued between the three of them.
Johnny decided that it was best to stay out of the fight for two very justifiable reasons. The first was he knew notions about the show and the second being he felt like the show was for girls. He could have simply get up and left but didn't due to seeing the fight as entertaining, decided to stay. After awhile though he grew tired of their ranting and had enough. "You know there is a way to settle this.." Johnny said getting in between the three very pissed off debaters.
"WHAT!?" Susan, Mary, and Dukey said in unison, venting their anger by giving him an angry glare.
"Build some kind of dohicky that will turn you into them and fight it out. While you were busy bickering, the hour long special went off. I am sure Dukey will have fun as a mare, so while you three are fighting I'm going to go play the new game I got...have fun.." Johnny said chuckleing as he walked out the room and shutting the door behind him.
"Ok...new plan," Dukey said a little steamed, now more at Johnny than the sisters. "he says I am gonna have fun as a mare huh? I say we give him a taste of his own medicine."
"Not to mention he laughed at us for liking the show..." Mary added already trying to think of ways to get even.
"He likes sports, so let's build the machine and use him as a test dummy, and I know just the mare to make him into." Susan finished with a chuckle as they got to work.
-few hours later-
Most of the rest of the day Johnny kept himself busy by playing the new Smash Badger game his dad got him for his birthday. He was on his last life and on the final boss and was charging up his finishing combo when Dukey came barging through the door, making Johnny lose the game by getting distracted.
"What do you want dog?" Johnny asked a little ticked, unhappy that he was so close to winning only for it to be taken away.
Dukey shrugged as if nothing had happened. "Oh nothing much, it is just that Susan and Mary wanted me to get you back to the lab. They said they iust finished that hoverboard you wanted." Johnny failed to notice the sly smile on Dukey's face as he bolted out the door.
"BEST. BIRTHDAY. EVER! Johnny said as he jumped down the stairs, he had been asking for over a year but it kept getting delayed. The suddenness of getting it raised a mental alarm, but he was getting a hover board so he didn't care.
"Johnathan, Johnathan, Johnathan..." Dukey said with a dark chuckle when Johnny was out of earshot, "you will get the hoverboard, but something tells me you won't be needing it shortly." He finished as he went out of the bedroom and headed for the lab. Meanwhile, Johnny had just entered it.
"Dukey said you got my hoverboard, is that true sisters?" Johnny asked as when he walked over to the.
"Indeed so," Susan said as she and Mary pulled it out from behind their backs. "Happy Belated Birthday." Johnny's eyes went large as he saw it, it was identical to the design on his shirt, but had 3 cyan lightnig bolts going into the biohazard logo.
"Wow, thanks guys," He said as he spotted something out of the corner of his eye. "hey what is that thing?" He walked over to a large object covered by a tarp and pulled back the cover. Underneath was a machine pained solid black with a red lightning bolt down the middle.
A mischievous look now adorned Susan's face. "That is the Ponymatic2000... It is what is going to turn me, Dukey, and Mary into ponies for the fight if we were having it.... Although I am curious, do you like speed Johnny?"
Johnny looked confused, he knew she was aware of his likes and dislikes, and he nearly didn't answer until it hit him that she might have been exposed to something and developed a wired form of memory loss. "Of course I do, why you ask?"
"You will see why..." Mary said as she turned on the control panel and openned the module as Dukey snuck up behind Johnny and shoved him in, causing the door to automatically shut.
"What the?" Johnny's voice was panicked as he started beating on the door. "Let me out of here now!"
"You are gonna have fun...Dash." Susan said as Mary flipped the switch, lighting up the inside of the machine and zapping Johnny with electricity. When it died down, the door opened and he came out normal.
"I am normal, so the machine didn't wor-" Johnny stopped as he started screaming, his body feeling like it was on fire from the inside out. He suddenly grew a bit, making his clothes shred as cyan fur covered his body. A loud snap was heard as his spine shifted, making him quadpedial as a rainbow tail erupted from his tailbone and his hair grew and changed to match the tail. The screams hightened in pitch as his Adam's apple disappeared and his vocal cords became feminine. His fingers shrunk into his palm as it changed into a hoof and his feet became hooves as well. His muscles, skeletal system, and body fat all changed, giving him a rounded but sleek look as his face pushed out into a rounded muzzle. His eyes grew in size and changed color, becoming magenta. His back arched as a pair of strong wings erupted from his back and a tri-colored lightning bolt appeared on his flanks. Then the final phase began, he started vomiting as his boyhood receded inside him, his organs shifted to make room for her new ovaries as her vagina formed on her rear above the butthole. A few minutes later, the new pegasus finally spoke.
"Sisters...wha-...what have you done to me?" Was all the mare could say before she passed out from the physical drain she just experienced.
