Jon picked up the ARD, god this was it, he was really going to do it, he was nearing climax, he was at his peak of wanting it. Speaking to the device, Jon said
"Make me a equestrian pegasus mare" The device beeped but it kept beeping longer this time, for several seconds. The changes were sudden but slower than what he had expected. He was still at the edge of his climax, desperately wanting to put himself into the mare he had just been looking at. He started to feel weird like his hands were cramping up his penis more sensitive, his skin itchy, Oh god what did he just do he started to panic, his scrotum began to tighten, tighter and tighter like an iron fist, It hurt, but it also felt strangely good. He couldn't stop himself he had to climax and continued to masterbate.
"Ahh," he cried out his penis was too sensitive it hurt to touch, and it was getting smaller, and his hand was continuing to feel like it was cramping up. He pulled his hand away briefly as he notice that his three fingers were fused together at tip. He took hold of his fading manhood once again, increasing pace, he shouldn't have done this, he shouldn't have made this change to reality, he increased his pace determined to reach his male climax before losing it to this mare hood he foolishly had set in motion. His scrotum tightened again, and then with a pop, the pressure was gone. He looked down to see what had happened, his balls were gone, the now empty scrotum continuing to contract, He watched still stroking what was left of his man hood, as his scrotum dissipated until it was stretched flat, he could see its seam, right in the middle of his body. There was a warmth coming from the area now, and he realized where his balls had gone as he felt them move around inside of him.
Shit this was starting to feel good, he looked at his off hand, His thumb and pinky had begun to move away from the other 3 fingers, well what was his 3 fingers, they had fused together and had started to elongate, forming the foundation for his forehoof. He still can't believe he had done this, It was clear the device was doing exactly what he had asked it to do. He started to notice a tugging at his ears like they were being pulled on. He reached up and touched one, it had started to elongate, it felt different, and after a few seconds he became aware that his sisters moans they had become louder.
"Ahh, Ahhh," he cried, his penis hurt, he stopped stroking, he had almost forgotten he was doing it. It was too much, he couldn't continue, he thought he better get out of this chair anyways before the big changes as he stood up out of his chair, only to find his balance was off.
"Its ok he muttered, its ok" and sat down on the ground, and then laying down on his back, and then to his side. In the process of moving his now 1/4 sized penis had rubbed up against his pants, it was too much. and he winced in pain. He should have taken off his cloths. He looked at his hands, they were almost hooves at this point but did they still have enough fine motor control to remove his cloths, he set out and did the easiest first, taking his feet he kicked off both of his shoes, the shocks would have to stay he guessed. He could tell by the shape of his sock that his feet had also began to change. Taking his two forehooves he pushed off his pants and wiggled free of them, sending jolt through his whole body as his now 1/8th size penis was shaken, He didn't think he could get the shirt off so he opted to just leave it be. His chest had already started to expand and the shirt had already started to stretch anyways.
"ohhh" he felt something, down where his scrotum was, he reached down and found that his scrotum had split, and was now starting to build up around the opening. There were so many changes happening now Jon couldn't keep track of them all. His face had started to push out into his new equine muzzle, his neck had begun to stretch to accommodate being a grazer species, His feet had fused similar to his hands and were elongating becoming his fetlocks. He looked for what was left of his penis, it was gone, only a small female mound was left. As the changes continued his sister grew louder and louder, or maybe it was that he could hear her better with his new ears. A stabbing pain came from his back and two bony objects appeared, he wasn't sure what they were at first, then he realized they were wings without feathers. He tried to flex them but found he had no control over them. He was still close to climax, his body wanted him to continue, this is gross he thought as he reached his forehoof down to where his scrotum had split, and touched it. When in rome, crossed his mind as he started to rub it. He could feel himself inching to climaxing again, but it was different somehow he wasn't sure how yet but it was different.
POP CRACK
It didn't hurt but it didn't feel good either, it was disturbing, his legs had been inching up closer to being in font of him and then had just powered through his pelvis locking him as a quadruped. At the same time his back had changed shape to help handle the new gate. His thighs were enlarging, fulfilling the equine form around his rear. He also noticed a rat like tail sticking out of him that had gone unnoticed. Fuck this really turned him on now, the doubts he had about this were starting to fade, he was almost through this, he started to rub his new vagina harder, He looked down and could see that he had a muzzle, it was still growing but was almost complete, with his off hoof he reached up and touched his ear, and then his face, he was almost a complete pony, but he had this weird human skin and no fur, or feathers. Almost like it could tell what he was thinking his skin turned pink and started to itch like he had never felt. After only a second he looked over himself, he was covered in pink fur. Oh right mare, how did I forget that. The shirt he had been wearing ripped with a sicking sound and exposed more of the pink fur sea. His wings itched too, and when he turned to look at them found them now full of feathers. A yellow or blond mane fell into his vision. This was it he was a mare. He had still been continuing to rub himself, he couldn't take it anymore he was about the climax, the idea that he was now a mare, was turning him on even more. Oh yes please fill me, he thought, I want to be filled, and he felt the familiar muscle spasms in his feet, and a new one from inside of him. He was shaking but he had reached his climax and it felt wonderful. He basked in the afterglow for a moment before crashing back down to earth.
"Wait what the hell was I just thinking" "I want to be filled" he thought about it, it was true, he imaged himself being the mare again, he still didn't like it, so why the hell had the thought that. He dragged himself up onto his new hooves. This was weird, if he hadn't made the device so that he remembered to the old reality this wouldn't be weird at all, but he had done that, he attempted to take a step forward only to trip over himself and fall back into the floor biting his tongue.
"well shit" He said trying to stand again, "I can do this, humans can move on 4 limbs and baby horses can walk without hours this shouldn't be any problem" He slowly moved inch by inch to his bed room mirror, except is wasn't his room anymore, it was more a girls room, with paper flowers in cyan and pink on the walls, posters of flying ponies in formation, and what appeared to be popular colt bands. But there was also some human boy bands that also were hung alongside but not nearly as prominently. Jon didn't notice any of this, he was to busy, looking at a very cute mare looking back at him in the mirror. She did everything he did. She smiled at him, and it took Jon a second to realize he was the one smiling. It was then he noticed it had gotten quite, his sister and her boyfriend must be done. He looked at this mare very closely in the mirror, no sign that there was a human boy in her mind clearly a mare her whole life. Wait thats it Jon thought, that is why I thought that, this body is a mare, its been a mare its whole life, I might have the same memories, but I have a mares developed brain that is why I wanted to be filled. Jon thought about it, when he was a guy, he couldn't explain why he wanted to put his penis in a girl, he just did. It was instinct, now that he was a mare, he had mare instincts, things that were hard coded that he couldn't change. Being aroused as a mare must trigger a similar instinct, he stared off into space deep in thought. If a stallion had been there right then would I have let him... his thought trailed off the answer Jon knew was yes but he also would have taken anything that would have filled him. The idea of a stallion still kind grossed him out, but simply knowing that he would allow it freaked him out.
Well he thought I'm a mare, besides what I just did what do mare's do for fun, he looked at the ARD, did he want to invite Karyn over, have girls day, or reset everything he wasn't sure what to do next. He decided to
