From Senpai to Kouhai (Mash Kyrielight TG)

This was an RP by me and LosANgelesD-14 on Deviantart they are a budding writer with a lot of potential.

I strongly recommend checking them out.

Kyle sighed as he lounged on his couch with his computer on his lap, eager to discuss ideas with another user on the server he created known as Mashing. He was easily one of the most active users on the server he had made and was grateful that he was there to give it life. His server needed all of the active people it could get.

The two of them had been discussing Self-TG’s last night and who they would want to turn into. It was fun and they had brought up all sorts of different characters from different franchises, like Caenis from Fate/Grand Order, Tier Harribel from Bleach, and Yuna from Final Fantasy. It had caused other members of the server to join in and saw who they would want to be and the ideas had flowed from there.

During their discussion, a small phrase sparked an idea that he was sure that his friend would love. The phrase was from senpai to kouhai. It sounded perfect in his mind for a Mash Kyrielight transformation. He knew that his online friend adored the lavender-haired kouhai so he was sure his interest would be piqued.

He threw it out there, and much to his glee, his friend did enjoy it and they did talk about where they could go with it and several ideas they had and where they could go with it. One thing they had, was where Caenis got turned into her twin. Before they got too deep into it though, his buddy asked where they should do the RP, and he decided that it would be best if they kept it on discord so they would be alerted.

“Alright keep calm, and don’t go crazy or pushy,” Kyle said to himself. He still had thoughts from it last night and the last few days about things they could do. The last thing he wanted to do was push his friend away, especially since this would be their first collab. He remembered months ago when he first joined said he had seen him as an inspiration and he didn’t want to disappoint him.

“So are you free for a while?” Kyle muttered as he typed the message and sent it off.

“Absolutely,” Idris responded. This is the first he has ever got involved in such an active project, especially something like an RP. Kyle has been his inspiration for starting his own stories, so to be able to interact with him in a way like this flutters his heart. And it’s not like he didn’t wish for this. Watching for a Mash Kyrielight TG is a far in-between in most stories he read, and it wasn’t satisfying enough for him to truly enjoy it. So, why didn't he just make it himself alongside his favorite writer? He switched away to Kyle’s private server.

“So, where do we start?” the first text appeared, seemingly waiting for the other person to reply.

“Immediately,” he received just a second later. One text is enough to convey their intention right there. Before their passion fade away to the background of a myriad of ideas, better to light it now before it dwindled.

His blood pumping, eager to showcase all of his dormant ideas up until now. “So, here, what do you think we need to do first with her?” Since this is his first time, it’s better to discuss it before they start writing. Learning is a lifetime experience after all.

They talked about ideas, setting, and plot while creating more ideas on the run. From outfit to personality, they’re going all out in this session to finally visualize the thought they had in mind for ages. And who could blame them? As passionate writers of the TG arena, it’s simply something that must have been done. Since it can’t happen in real life, then why can’t they imagine it in this virtual world instead?

If only BB existed, in real life, Idris thought, then it would have been better. He didn’t wish to sacrifice anyone for this, but maybe a little miracle is enough.

Unbeknownst to both of them, a third party merrily observes the passionate writers replying to each other, grinning madly in the idea that has suddenly afloat her mind in that instant.

“Oho, now I can’t reject that wish, can I?”

The third-party watched inside the web, their long purple hair flowing behind them as she watched the conversation play out. She had been following their conversation ever since it had happened to the guy who went by Warden on their server. The young woman had just been going through looking for something to kill her boredom when her name came up. She hadn’t put much into it at the time but decided to keep watching for curiosity’s sake to see. It had been a shock to find out what they had thought about using her for in full context, but it had certainly caught her attention.

Ever since then, she had been going through the logs, to see what else she could glean about the two while following the conversation. To normal humans, it might have been a little troublesome, but to her, the great BB, it was as simple as moving her fingers. She double-checked to make sure that they weren’t randomly going to change what they decided to do.

“You two better not change how it happens, or else I’ll be insulted,” BB said as she dug further through the old logs, looking for any other good material that she could. “There you are wanting to use me for a special project like this only to toss me aside. I would need to get back  at you two if you did.”

“Ohh,” BB mused with a grin as she read over one of the oldest logs. The other one who went by Mashing had quite the admiration for their senpai and had asked for feedback for ideas and their work before, and much like a good senpai, Warden was there to help him out and refine his work. “Well as one kouhai to another I’ll make sure that you receive the best help possible.”

A ping on the conversation caught her attention and she turned to see that they had decided to stick with her being the cause, making her smirk. A mischievous giggle left her mouth and she rubbed her hands eagerly. A clipboard appeared in her hands that contained all the notes for what they decided upon.

“Well it does seem like they want me to be the cause of the transformation,” the girl laughed. “It seems like they are finally going to start figuring out the rest of the details. Don’t keep me in suspense boys. Let me know how I can help you two.”

Back in their server, Idris and Kyle have already started. Beginning with a constructed interaction, they slowly but surely moved the story forward. They have already put in BB the plot device, and the events that are about to ensue are simply the endpoint of the dominoes they’re building up for.

“Now before we got to the main transformation, why don’t we start with some low tiers first?” Idris asked about the tiers already planned by both of them. Like all TGs, they had to start with smaller parts like hair, nails, and skin to prep up the larger parts.

As Kyle waited for his next response, he thought to himself. Being a writer himself, he understands the struggle of continuing the next paragraph, abandoning certain ideas for the sake of the story and better ones. Such is the struggle of writers. Besides that, he was also thinking about what would his character’s reaction be when Mashing’s paragraph is finished. Will he expect him to be shocked, embarrassed, or something more? He smiled in his mind, eager for what it might be.

Several strands of his hair, black in complexion, began changing to violet purple in its stead, replacing his natural black hair color one strand at a time. He couldn’t notice it as he continues to ponder the possibility, lost in his mind with the imagination of Mash.

But, it wouldn’t last for long. As his hair began to cloud his eyes and enter his vision.

“Huh,” Kyle said at having something enter his vision, wondering what it could be. He was thrown off by the unique strand of lavender, wondering where it could have possibly come from. There was no way that it was his hair. He had gotten his hair cut a few days ago and it would take much time before it could enter his vision again. He shrugged and moved to move it out of the way.

A faint tug on his head made him stop. He ran his hand through his hair, wondering if there was something in there that he hadn’t noticed, hoping that it wasn’t a spider or some form of insect. That would have made some sense at least. As he did he noticed that his hair felt a bit shaggier than it did before, as if it had been much longer since his last haircut.

“Nah there’s no way it’s really growing,” Kyle said to himself.

After his failed attempt at finding something off, he pulled again, only to feel the same tugging he had when he first tried. More strands of the same lavender color entered his eye’s view and were the same shade of lavender as they first entered. He pulled at them and it felt like he was pulling on his own.

“What the hell,” Kyle muttered.

Something tickled the tips of his ears, making him shiver. He reached around and could feel soft locks of hair around his head that were seemingly growing longer in his hand. He grabbed a handful and breathed in and out as he tried to calm his beating heart. Much to his horror, the growing strands of hair he felt didn’t cease and continued to grow. He pulled it into view and saw more of the same lavender fabric enter his vision.

“What?” Kyle muttered as he pulled, feeling the same tugging sensation as when he pulled the lavender-looking strands earlier. “This can’t be my hair. There’s just no way.”

Luckily for him, his hair’s growth stopped once it reached the shoulder blades, leaving behind a short, lush violet hair in its wake. He sighed in relief. Should it be any longer, and he might have to deal with a new issue. Slowly, he touched his newly-made hair. Soft like a fresh pillow, and smoother than silk. That’s the first two descriptions he could make from his observation of his new hair. Somehow the shape and shade of it looked familiar as if he had seen it before.

“Why is this happening to me?” Kyle wondered. His head is spinning with questions. Is this really happening? He has made several self-TGs before but never thought that it would happen in real life. What was the cause? He hadn’t done anything special that would stand out. All they had done was discuss a TG story idea. He considered more outlandish ideas and stopped when a thought came to him. BB…..his head came up with one of the possibilities but it was rejected outright. No way, no way. BB isn’t real. She can’t just appear out of nowhere!

But what else could the answer be?

Kyle stopped thinking and breathed. Calm down. Calm down. There must have been an answer somewhere. He remembers back the few moments before it started changing. And one of the clues is……

The now violet-haired boy looked at his computer and stared at MashingGun’s paragraph. He had written the transformation of his hair first and the reaction that follows, although he got the wrong idea for his reaction. Does it mean it’s really happening to him? He’s going to turn into Mash? He doesn’t know why, but the idea of it somehow intrigues him, enough to cover up the anxiety earlier.

He needed to prove this and make sure that it wasn’t just a theory. And thus, he began writing the following paragraph, detailing the reactions afterward and the thought process behind it. The new hair obstructs his vision at times, but he was adamant to see it through.

ANNDD….

CLICK!

His new paragraph was now uploaded. All he needed to do was wait for Mashing to respond, and he would finally get the answer if it was the cause of it. Sweat began to flow profusely from him, in the coming minutes as he waited for his response.

One minute.

Two minutes.

His legs started shaking. His mind is on the verge of taking another direction and asked him to cancel this whole RP. The part of the mind which feared the idea of transforming is becoming more evident, nearly enough to overtake the minor curiosity he once had.

‘Mashing, hurry up please,’ he thought.

It was only before he took another step, that a response was made. He read through it, his mind focused intently on the next transforming parts. Body hair and hands.

The young man felt a chill throughout his body. He hugs his body, his sensual organ all react before the freezing sensation that has occurred. Please wait! Please wait!-

SCHIIKKK!

“Oof!”

All of his body hair, from face to toe, immediately reacted, pulling itself in all at once. Kyle fell back to his couch, understandably shocked by the transformation. His body went straight into spasm, shaking uncontrollably from the suddenness of it all as if ice had been poured down his back until he finally calmed down. And with it, his thoughts began to resume.

Kyle breathed through his nose and looked down at his softening hands. The neatly trimmed nails were cleaner than he normally would ever have them be. He would have just taken a pair of nail trimmers and used them to clean them up. The changing young man breathed as he turned his hands over as if he was looking at something new. They looked different, but they still felt as if they were his, despite the changes happening to them.

He curled his slimming digits, shivering at the touch of them against the palm of his hand. When his hands finished changing they were unrecognizable to him. His new hands would have looked like they didn’t belong at all on his body if it wasn’t for the hair that he had lost on the rest of his arms

The thought of the rest of his body made him let out a hesitant sigh as he pulled at the bottom of his pajama pants to look at his legs and saw the hair on them was gone as well. He let out a breath and let go of them. That was all the proof that he needed to know the rest of his body was just as clean as his arms and legs. The lack of body hair made his clothes feel slightly off as if they were older than they were. Even the soft silky pajama pants felt different.

His mind was still abuzz with activity and he could hear his heart pounding as if it was right next to his ears as his mind went over the changes to him. The young man felt his new skin and shivered from the softness of it all. It was softer than it had been for years. He was no expert on women’s skin, but it had a natural softness and cleanliness that he knew many would kill to have. The fair skin added a charm that would have drawn people to him like moths to a flame. Now that he had it for himself, he could see the appeal, even though he wanted his skin back.

“Ok I think I need to call this off,” Kyle said and moved to type it out, but stopped. From what he knew of the Moon Cell Sakura AI she was a little imp who loved to have fun, like an impish trickster. He gulped and said. “BB if you are causing this. Please stop.”

“Ehe.” She put out a small smile. Honestly, this is getting more interesting by the second. These two humans are simply too amusing to watch. Another one is an ignorant idiot, while the other simply wants to stop. It only serves to inflate her curiosity with them and the result later.

But…...is it time for her to reveal herself? If she would, she could have just revealed herself in all of her glory and hounds all of their attention to her. This is what she has always done in all of her appearances. However, this one is an exception.

She took another bite of the crackers EMIYA made. This is her lazy period. She won’t waste her time appearing on somebody else’s computer, especially to humans she doesn't care enough. Most of what she would do is just messing with them indirectly and led them go to their own conclusion. When thinking back about it, isn’t it a more entertaining outcome?

And so, with nothing to do and nothing to lose, she continued her interference, completely devoid of interaction with her playtoys as she observed their behavior.

.

.

.

.

Alright, maybe there is a little. But it won’t be so big, not at all.

“NO~”

A sing-songy voice rattled through his head, one familiar enough to gain an answer to. And with it, confirms his suspicion.

BB…… The imp really does have a hand in this. And with her word, it seems like she won’t be stopping any sooner. He sighed. Not for the fact that a fictional AI character does exist, but for the idea that she’s entertaining all of this.

“I’m doomed,” Kyle muttered. She won’t appreciate him stopping at this point, and he feared what kind of repercussions he’ll get from disobeying her. Once she set her mind on something, it’s impossible to stop her except if you’re her Senpai, which he’s clearly not.

And so, he returned back to his computer, now with resigned acceptance. Instead of writing a paragraph, as usual, he texted Mashing. “Hey, Mashing, would you mind if I open the video? I got something for you.”

On the other side of the web, Idris was baffled by this sudden request. Why would he ask to open a video so casually? He didn’t think that they were friends to the point of opening up to see their real appearance, so why would he choose this?

Idris replied, confused, “Why Warden?”

Kyle simply responded, “You’ll see.” And a live feed is on.

And his first reaction?

“Whaaaaattt?”

It’s just a normal guy with dyed lavender hair. If Warden is this daring to open up his live feed, then he must have been so bored. Ah, so Warden is that kind of person. It comforted him. To be able to know him and his face as they interact with each other. Maybe he should do this as well.

Before he opens up the camera as well though, he mentioned something. “BTW, Warden, what do you want to show me?”

“You’ll see,” Kyle sighed shakily. There was no way that he would be able to just open up and say it. At least not without any proof backing him up. It would be insane to say that he was being bullied by a fictional character. Something like that was only supposed to happen in fiction. “You won’t believe me unless you see it for yourself. Just put up with it, at least for now please.”

Kyle breathed in and out, typing out the reactions for the story, finding some peace in doing so. In his mind, he could envision what would happen next in the story clearly. The pounding of his heart eased and the storm in his stomach wasn’t as prominent. Still in the back of his mind, he could feel the worries that he had about what might happen.

He wondered if BB was watching in the cyberverse reading his work right now with a devious smirk, waiting for him to finish so that Mashing could start the next part of the story. A part of him wanted to just turn the computer off and walk away, but there was no guarantee that it would stop her. She would probably give him a punishment that would make everything worse for him and more fun for her. And her definition of what would be fun was no doubt very different from his.

A thought struck him and she wondered if she had seen the artwork dedicated to her and what she thought about it. He wasn’t sure how he would feel if there was so much art on all ends of the spectrum from tame cute ones to lewds. Especially the comics and doujins that featured her in a variety of situations.

“She probably doesn’t mind them,” Kyle sighed since the world wasn’t overrun with hundreds if not dozens of BB’s. When he was finished he pressed sent and breathed out. “Alright now it’s your turn. When you’re done writing and send it. Just watch me.”

Idris is confused at first but decides to ignore it under the pretext of him being bored. Immediately after, he covered the video with the writing board and began to return back to writing the next paragraph. Within each writing prose, he was getting far more passionate than ever. He may not be the best writer, but nobody could deny the riveting sense he’s feeling right now.

He wondered which he wanted to change next. Imagining the change was easy, but to portray it? That was another matter entirely. For the body, it could be easy. All that needs to be done is to just slim and heighten it, right? From the shoulders, hips, and legs, all of it will change as well. A hell of work, but not too hard for him. But, just before he started writing, another part also came to mind.

What about the face?

Although Kyle changes physically, it wouldn’t be as prominent as the one on the face. In-story, he will be more reactive to him if his face and voice become similar to that of Mash’s. It would also mean he got Mash to speak normally from her original position in-game. A rise came from his heart. His thought raced. It will be so cute, finally got to see her face-to-face.

Idris was pumped up now after that train of thought. It completely replaced his original idea, he began to write the face transformation first before finishing on the body. It’s a hell of work, but the thought that stayed in his mind continually pushed him forward. For her sake! For her sake! He can’t wait to see her real form when they were done finished writing. This might be the only time he has the opportunity to write this together, so he has put his all into it. His writing is like that of lightning. Only in a few minutes, the text reaches its completion.

“Hooray!” he shouted, though not too hard as to be noticed by anyone else. He silently celebrated in his heart, before finally sending it to the message board.

“How’s that, Warden?” Idris asked.

On Kyle’s side, he gave out a small sigh. So it has come to this. In all honesty, turning into a girl, especially a cute heartfelt girl like Mash wasn’t so bad, but as long as he didn’t try to change his memories or shifting reality, he’s pretty much screwed at all fronts. What would his parents react to him-then-her after this? His colleagues won’t recognize, nor the registry. All the real-life consequences will diminish all the short-lived happiness and be replaced with a cold reality.

CREEAKK!

The first signs of his transformation are beginning. His expunges all of the troubling thoughts and bear with it. No matter what he thinks, it will be all the same. This is a real-life TG, after all. Better to make the best of it.

And with it, it began to change. His masculine jawline, one that he has had so long, became curvier and rounder as his chin softened. Alongside his jawline, his cheek and skin change as well. From the rough, rectangular, sunken shape as it is, it’s changing to a more rounded and softer complexion, befitting the cute figure he’s becoming. His nose is also no exception. With little pressure, it sunken down quickly and become cuter in an instant. In a blink of an eye, his eye color is now violet-purple from the hazel brown it once was.

During the transformation, he let out nothing more but a grunt with all the changes in his bones and skin. Yet, even he feels as if his tone is becoming much higher. The Adam’s apple that has been a male’s trait for so long is losing its definition, becoming smaller and smaller in the process. He knows it felt uncomfortable in some of the TG’s he’s written, but to feel it himself is nothing short but a discomforting experience. By the end of it, there’s nothing left of the organ, only the bare neck of his.

“......Testing, testing….” A feminine voice came out of his mouth. No surprise there. Now that he’s voicing Rie Takahashi’s voice (in English nonetheless), he has to admit, it does sound cute as hell. Ritsuka over there, you’re blessed, man.

He stopped wandering off his mind and returned his eyes to the screen. He spoke clearly, proving to the other side about his earlier request. “....See?”

Idris couldn't say anything as he stared and make sure that he wasn’t seeing things. He pinched himself and yet he didn’t look any different at all. He didn’t want to believe it was happening, but he had seen for himself that it was true.

Kyle squirmed slightly from the look he was getting on the other hand. A nervous blush adorned his face. Now that he knew what was wrong, he couldn’t help but feel like he was under a microscope.

“How could this happen?” Idris said, his mind trying to make some sense.

“For a moment, I heard her, BB,” Kyle said quietly. He was unnerved by the voice that left his mouth. It sounded so strange to hear it come out of himself. “I just asked her if she would stop it, but all she said was no, and that was proof enough.”

“That can’t be,” Idris said, his mind desperately wanted to say that it was a prank. “But she...she isn’t real. She can’t be real.”

“Oh but I am,” a woman’s voice resounded through his head that made him jump.

Idris looked around the room, expecting to see someone in the room. He looked down at his computer, expecting to see something off about it, but it looked normal.

“Oh you won’t see me down there,” BB said. “I don’t need to affect your computer.”

“It’s really you isn’t it?” Idris questioned, pale at the thought of her being real.

“Yes, it is I, the great BB,” the AI said happily, and the young man could easily imagine her doing a little twirl wherever she was.

Idris gulped, wondering what he should do. Her voice sounded exactly like it had Fate/Grand Order. There was no way they would be able to do anything about her. She could do so much to this world and there wouldn’t be anything that could stop her.

“You just heard her?” Kyle asked though it sounded more like a statement.

“Yes,” Idris sent back, his fingers feeling heavier. His heart felt like BB had it in a vice grip. He ran his hand off his brow, trying to think of what they could do. “You heard her too?”

“Yeah,” Kyle confirmed.

An uneasy silence came over them, Neither were sure what they should say or do. With her watching and causing the changes. The two doubted that they could just turn off their computers and everything would be fine.

“Should we stop?” Idris asked fearfully. As much as he didn’t want to break off the story, especially with one of his favorite writers when it comes to TG there was no way he wanted it to happen, especially when he considered the full consequences. “If this story is causing the changes then if we stop now then they should stop the changes.”

“You can’t stop now,” Kyle quickly said in a panic. He looked down at the screen, half expecting BB to appear on it and looking angry at the two of them for even considering the idea. Much to his relief, the last thing he needed was for her to get angry. “We have to continue the story. What if she gets angry and decides to change both of us?”

“I know what you mean, but I can’t just continue knowing what’s going to happen to you,” Idris said.

“Do you want to suffer a punishment from BB?” Kyle asked. “Just keep going. This way at least one of us is fine.”

Unknown to the two, BB smiled in her little domain in the cyberverse.

“Oh,” BB sighed happily. “He is a good senpai with how worried he is for his little kouhai. Oh, he’ll make a perfect kouhai for him when he’s all done.”

Idris breathed heavily, all the thoughts he had on continuing the story all up in smoke. He looked at Kyle. She...he, Idris corrected himself, was beautiful. He always wondered what Mash would look like in the real world, and now he was seeing it for real. Now though he wished that he would be able to see it under far better circumstances.

“I don’t think I can continue knowing what might happen to you,” Idris sighed.

“I’ll do the next one then,” Kyle breathed out.

He started to write what came to his mind and found himself relaxing again as he did. So focused on his work, that he almost could ignore the hair brushing against him. A smile came to his lips despite the situation. The heaviness in his heart lessened and the pressure on his stomach as well. He tried to think of how he could make the sentences unique and interesting, thinking them in his head.

Far sooner than he expected he finished the next bit describing the waist. The changing young man took a deep breath and braced himself for the change to come. He breathed heavily and forced himself to send it.

“And now to give you that waist!” BB cheered.

Kyle jumped in his seat as if he had been shocked, and then as if someone was pushing down on the sides of his waist and his stomach. He hugged himself, but still, the feeling persisted as it grew in tenacity. He squealed as if he had been shocked as his waist started to cave in, his face warming up as his body started to heat up. The flabby stomach that he had hardened and he pressed down on it as it did. He mewled and shivered in his seat as it continued to get worse. The changing young man rubbed his stomach and flinched as a shock went through him that made his body heat up slightly. When the change finally finished, he let out a breath and noticed how much further his arms pressed into his sides and how much leaner his stomach was.

The lavender-haired young man raised his shirt, exposing his slender waist and smooth flat toned stomach. He blushed at the sight of it as his heart went cold. It was so strange to see it, and his mind stalled at how different it was.

But that wasn’t the end of it.

“Hey! Who said the passage’s over. We got more to finish with!” BB mockingly complained.

Before he got another chance to reply, something else changed in his body. Following on his waist, his entire torso contorts with the proportions, becoming slimmer and smaller as his muscles begin to lose weight. He tries to calm his body down, hugging it with all he got. Yet, it’s only something inevitable as the transformation happens somewhere else. As it's getting slimmer, it’s also begun to grow. He could feel his body stretching out beyond what’s allowed, yet he couldn’t feel any pain from it, just mere discomfort like an acrobatic master. He might not notice it, but if one looked closely, one can see the heightening and slimming body no longer looks like it’s regressing to the figure of that of a petite, young girl to that of a mature, slender lady. There is no way for her to care what kind of figure she’s turning into because, in a second, all of that will be thrown away with the most impactful change he has ever felt for now.

CREEAAKKK!!!

“Gaaaaahhhhh!” Kyle squealed in pain. It wasn’t the skin changing, it wasn't his hips changing. It is the spine. For the other parts that changed, it simply shrunk down or has a little modification to its position. But for the spine, the big one that controls all of his body, a slight change might as well feel like a boulder hitting the back. He pulled back to the couch, laying down while his body squirmed. The elongation of the spine was not like the other change. It wasn’t reforming anything, shrinking down or modified. It’s creating new bones in its stretch. Despite the reforming bones and nerves with the newly-made backbone, it couldn’t stop the burden of its stretching that comes from its elongation. If only for a few moments, minutes(?), should the ordeal end.

“Aaahhhh…” he released a voice of relief. It’s over. It’s over. With his shaking hands, he wakes up to his sitting position, focusing more on trying to comfort the nervous Idris. He didn’t close the video, after all.

“Are...are you alright?” Idris begged, already fearful of the grunt Warden’s making.

“I’ve been better,” Kyle said, a little touched by the concern that he had for him. His body was warm and he knew it wasn't from the heat. His cheeks burned and he breathed in and out as he tried to help his body relax. This was the kind of waist and stomach that he would have dreamed about on a girl. He prodded his stomach and gulped, it had a hard tone that it never had before and the pleasing warmth grew.

“Now I can understand why you would want to look at your body, but you have something important to do. You need to continue with the next part of the story. Don’t keep me waiting too long, or else I might start doing the rest of the transformation myself,” BB sang.

Kyle breathed out and began his work again, this time going on about the legs for the transformation. It was the only thing he could do without running away and earning the wrath of the formerly fake character. After a few sentences, he breathed out to see if he could find anything wrong with his next bit, but couldn’t find anything off.

When he finished the next bit he looked over Mashing’s work and then his in response to making sure that it made sense. A frown formed on his face. For some reason, he found it lacking as if he didn’t have enough detail in it, even though he did everything he could to try and make it unique. He shook it off and after a moment he sighed and sent the next portion.

“There we go, BB,” Kyle said. “Happy?”

“Very!” The AI cried. “And as a reward, you are getting a new pair of legs, just like the ones you wrote about.”

“Oh!” Kyle cried as the soles of his feet felt like were shoved in warm sand on the beach. His toes curled and he shivered on the couch. He breathed heavily through his nose as he watched the changes. He raised his feet to get a better look at them, unwittingly putting his full legs on display for Idris and BB to see.

The boys could only marvel as Kyle’s feet got smaller along with his ankles. They curled off their own will and despite the change in size they still felt natural, which he wasn't sure how to feel about. Soon he had small petite womanly feet that looked unnatural on his masculine-sized legs.

The changes continued up his legs and they quickly reached his thighs and they started to grow as if some of the lost mass was returning on them. His underwear strained against his changing thighs, digging tighter across his lower body. The changing young man shivered from the soft thicc flesh rubbing against his hardening wood, which only made the pleasure grow. The immense pillowy thighs rubbed against each other, his dick stuck between them as if it was caught between two walls.

“Hmm,” he whimpered in discomfort with a blush and then panted as a needing burning warmth between his legs swelled. His dick rubbed against his new thick thighs. He tried to adjust his thighs, but all it did was make the arousal more prevalent. With an embarrassed and aroused blush, he spread his legs and let out a pleased sigh when his dick was no longer stuck between two thick sexy pillows. He didn’t care that it might have shown off his new curves, he just wanted a small reprieve.

“Oh damn……” Kyle commented, already tired from the change. While it’s not over yet for some parts, he at least could be relieved that this is the end of the change for now. Before the inevitable happens.

“Warden…..d-d-don’t expose your legs like that…..” Idris said. Despite the pain he has witnessed earlier, he is slightly aroused by the figure he’s turning into. He knows what he’s feeling is wrong but, with everything that happens right now, wouldn’t it be unreasonable to gaze at those feminine features he helped create? And those legs, oh god, those legs. It was only with his half-baked self-discipline that he hadn’t wank off to this yet. Stating as his dick already hardened by the change in his torso.

“Oh, come on, Mashing. Don’t tell me you’re not into this. I can imagine you on the brink of wanking off back there,” Kyle replied, feeling a little insulted. “Sooner or later, these plump, thicc thighs, alongside those melon boobs and ass will be by your side all the time. And I won’t regret any second of it. So why are you still holding back there?”

Idris gulped. He never imagined it would come to this. All he wanted was a good, nice fantasy writing with his favorite writer and senior. How could it turn into this?

“But….what about your life? Parents, friends, career, will you be fine if you turned my…..ideal fantasy?”

Silence. He didn’t know what to say. It’s fun and all, but for him to sacrifice his friend’s life for this, wouldn’t it be horrible? BB may be on his head, but it’s only him that writes the story. The Mash he’s fantasizing will be the Mash Warden’s turning into. Will it truly be fine for him to shape even his personality to fit his dream?

“Say….”

“Huh?”

“If you’re in my shoes, what would you have done in my stead?” he questioned, pushing ahead.

“I….I’ll….” he doesn't know how to answer that. Maybe if he’s in his shoes, maybe he would enjoy it perhaps? If he’s turning into what they both agree on, then maybe the transformation would felt less alien to him. With doubt and confusion, in that moment, he would have…

“...Probably turn into a slut at that moment,” Idris answered. He won’t sugarcoat it. Turning into a female is simply too much of an allure for him to care about the long-term consequences. “Unless you write me as a pure and innocent saint of a girl, I will just blow up in all directions. At least, that’s what I’m hoping it would be.”

“Ah…...so you’re that kind of guy…,” BB commented.

“Whose fault is this in the first place?!” Idris shouted.

“I don’t think it was me though,” BB remarked with what he imagined, a smug smile.

“Well, at least you’ll be a more interesting person to TG,” Warden interjected as well.

“Warden, please shut it. Don’t give her much inspiration!”

“Ohohohoho! Is that the begging of an ignorant human over to my choice? Did you think you could stop it once it was entrenched in my mind?” BB laughed haughtily. Being the devil she is, it might be a possibility in the future.

“Okay, I’m screwed,” Idris talked to himself.

“Hah,” Warden smiled a little to himself as he watched Idris’s reaction. It’s not like he’s enjoying any of this, but maybe….he could at least scrape up some sense of fun from here.

Idris focused back on his monitor, writing something of note. “BTW, what about your answer? Your whole life right now, would you want to abandon it?”

He ignores it completely for the sake of another question. “Mashing, which part is next?”

“Eh?”

“Is it the boobies? The ass? The dick?” Warden questioned again, this time blunter.

“Wait a minute! What about my question?”

“You know what? I’ll tell you this once we got over this. For now, just see me as an unfinished sculpture, okay? Write it as beautifully as you want it and finish this.”

‘Warden’s awfully calm about this,’ Idris noted. Although he is on the verge of losing his original body, he kept on being rational and calm despite our situation. Is this what being a senior truly is?

“Okay, if you told me so,” Idris muttered. With a deep breath, he returned to writing. He doesn't have the will to write as passionately as he did now, with all that’s happening. But Warden’s expressions don’t give him the refusal he truly needed, as if he condoned and accepted his course of action. He admitted he isn't a good person, and the absence of any refusal reignited the flames that have been burning for now. At this rate, he may even go for the full experience.

And so, it began.

The last physical parts I have to write are already here for me. The final parts will define  The treasures of the female body. The object of worship for eternity, from gods, humans, and animals alike.

Boobs and Butts.

Since they agreed on an Adult Mash TG, every proportion was made to make it as mature and sexy as possible. And with the display he’s seeing there, it was working better than expected, though BB still has a hand in this. And so, that means he needs to make it as big as possible to ooze out ara ara potential to its maximum level. With that kind of size and personality that follows suit, they might get the best of all possible worlds. A small satisfied smile could be made out of him.

Let's make the sexiest kouhai alive.

Idris breathed out as he tried to think of what he should start with first. Both were appealing and had their perks. The idea of seeing a pair of large heaving breasts form on Kyle’s chest was interesting and even mesmerizing to imagine. That didn’t mean the butt was any less appealing. It might be best to go with the butt for a story perspective. Stuff like the boobs was usually held off for the final point, like the grand finale.

“C’mon don’t keep me waiting,” BB whined.

“I’m thinking of how to put it to words,” Idris said as he paled, hoping it would appease the magic computer program. He quickly started thinking over what to do and allowed his fingers to begin the next stage of the story. As he did he looked back at Kyle who sat there, still with his legs spread out. It was hard to focus with how similar he looked to Mash right now.

When he finally finished he breathed in, his finger hovering over the enter button. Guilt welled within him, despite his anticipation and Kyle’s words reassuring him that it was ok. The moment he pressed enter he turned back to see the transformation begin on the other, a little excited to see it happened.

“Ahh!” Kyle cried as it felt like something had been shoved between his cheeks. He quickly stood up and grabbed his rear as it warmed up. He bit his lip as he could feel his ass warm up. The feminine young man gulped as his buttocks rumbled and then slowly swelled. The erection that he had from the transformation started to renew and tent the front of his pants. He breathed heavily at the growing tightness that only made the change to his lower body even more sexually stimulating.

Idris could see the erection that he had but didn’t mind it much. Unlike some, he didn’t mind futa as much as some people did. Granted it was a little weird to see a guy do it and the whole situation in general. Still, he was happy that his full body wasn’t on display lest he make things weird by having his hardwood on display.

Kyle moaned as his underwear pressed down tighter on his throbbing wood from his growing behind. He bit his lip and moaned lewdly at the stimulation that went through him. The small legs of underwear already strained against his thick thighs, but the strain against her underwear only worsened with her ass growing. Despite the lust that fogged his mind he still remembered that he wasn’t alone. His wood demanded his attention, and all thought of proper decorum was gone from his mind for the most part. The changing young man massaged his growing rear with one hand as the other massaged the front of his pants.

RIIIIIIIIIPPPPP!

A tearing could be heard, but he didn’t care. He continued to massage his expanding rear, despite the tear in his underwear. The tearing sound continued as his ass continued to swell to proportions that he never thought it would be in his entire life. The changing young man breathed heavily in and out, as he continued to molest his engorged rear, which was far too big for his hand to fully contain. He turned himself around so that his growing ass was on perfect display to the pair.

“Oh, that is quite the sight wouldn’t you agree?” BB giggled aloud. “Looks like someone is feeling naughty.”

Kyle wiggled his hips and started to thrust back and forth, making his developing rear bounce enticingly. The changing boy grinned at the change and continued to thrust his butt and bounce his rear, savoring the way it did. The growth soon started to slow, much to his disappointment, and the tearing noise stopped. Yet much to his glee, the surges from his molesting didn’t die down at all. If it weren’t for his pajama pants then they would have been able to the massive tears that would have exposed her fair developed buttocks.

“Warden?” Idris said warily.

Kyle turned around with the same dark excited blush that they first saw and now could see he was massaging the tent through his pants. “Yes?”

“Are you ok?”

“I’m...just,” Kyle panted heavily with an excited grin. He licked his lips. “I’m just so hot. This is amazing!”

“Why don’t you turn to the side dear and show us how big it is now?” BB said.

Kyle did as he was bid without question as he continued to fondle the hill of his masculinity, almost without a care. He looked over at his butt and smiled at the massive ass that looked like it could have been the definition of thicc. It was a huge massive round thing that would have been impossible to hide from the world. Even through the loose pajama pants, he wore it was clear how big it was.

“Oh my it looks like someone now has a dump truck of a butt,” the AI laughed.

Idris could only stare at the rear, happy with how it turned out. He knew he had described it to be big, but this was unprecedented. It certainly fit what he had in mind for ara-ara Mash. For a moment he wasn’t sure if he should thank all the deities and BB for this golden opportunity to see his waifu in all of her sexy glory.

Kyle’s mind went to the sensation between his legs. For a moment he stopped as a thought went through him. It continued to build and wondered what it would be like to have a new set of womanly lips down below. Would it be more pleasing?

“Mashing!” Kyle said eagerly, hungrily.

“Y-yes,” Idris said slowly.

“Please get rid of it!” Kyle said as he fondled the front of his pants with one hand, breathing heavily. “Make me a full woman!”

“.......Alrighty, then!” Idris quickly returned back to the writing board. He couldn’t care less anymore. Warden might be enjoying the final moments of his masculinity eagerly like a slut, BB might be the one to decide but he's the writer here. He'll be the one to decide how much he'll enjoy this. And by the looks of it, something needs to be done for him to truly reach the climax of this writing.

Heh. A smile on his face, one so devious it might be obvious to those with a better one. If this is the best you can make, then you ain’t see anything yet. He’s a goner anyway. At least, he could give the honor as a man and as a TG writer, the greatest boner of his life.

Taps began to rush. Words continue to appear side by side. Description, every single detail imaginable in his head began to rush in as the climax of the TG is in its first stage. No amount of excitement could truly be able to top off the moment he’s craving. From her moans to her awkward pacing, he has detailed it all at this moment.

And now…..

“Let’s start.”

He copy-pasted his words to the server. For a few moments there, Warden sat normally as before, spreading his legs out in anticipation. Then, soon enough, a new sensation is made.

“UUGGGGHH!!!”

His stick began to harden again, responding to the new erection this new transformation is about to do. His mind didn’t hesitate at all as he grabbed the hardened stick and rubbed it roughly, further intensifying the feeling. The effect of the transformation itself isn’t obvious enough, but if one would notice that his stick is no longer as big as it was.

“GO, GO FOR IT!”

Naturally, with the amount of impulse and attraction he’s getting, it was only getting in succession to the process. Like electricity, he proceeded to rub his dick faster to enhance its stimulation and the result is astounding. He fell deeper into depravity as his stick shrank.

‘HOLY SHIT! IT FELT LIKE FUUUCKKKK!’ His mind was severely clouded from the pleasure of the experience. Even if he has masturbated multiple times before, never once it has reached this level. Is it because his receding dick is stimulating his dick this much? Have his female hormones begun to form? He couldn’t care less as he played with it even more.

The transforming man fell to the ground, preferring the free surface of the ground as the transformation began to hit on his hormones. The changing hormones, clashing with its different commands, confused the poor young man with its conflicting feeling. Yet, both of these commands followed exactly the same purpose and that is, to pleasure. And so does the man, a mind conflicted by two different natures, united in its joy.

“AHHH, this is so much fun!!!”

Idris watched from the other side, following on his action as he pleases himself with the result of his words. He is reacting as planned. It is simply the start of the transformation and he’s already fallen to the ground. Wonders how he’s going to react next with his next surprise. He realized, ‘He didn’t even read ‘till the end.’

Back on the other side, Kyle was having the time of his life. “SO HOOOTT!! SO HOOOTT!” he shouted joyously, his hardened dick already became shorter than before. Despite multiple moments at ejaculation, he never seems to be able to truly release it. His cum, which has already reached critical mass, only stopping at the tip. How frustrating it is to never cum at this point, Warden began to began her barbs.

“Ah, Mashing…..do you really want this?!” Kyle questioned in frustration.

“Yeah,” Idris answered, not even flinching. He watched as Kyle struggled to keep himself together, he sated himself with the curiosity of later events.

Kyle let out moans of perversion. By not being able to cum, all of his energy was moved instead to build up his intense masturbation. As his masculinity shortened, his femininity began to show up in the most personal parts. His mind, which has been filled with nothing but sexual thoughts, covers the transformation within.

He couldn’t understand where it’s coming from, but his state of confusion was soon replaced by a soothing sense of enjoyment, lulled by the dreams of the result. Little by little, he became softer and submissive to his impulses, shedding away the old identity he was made with.

“Ah, it’s going off….!” his(?) instinct roared, the nether began to lose all elements of masculinity. The stick, which has shriveled so much it’s as small as a pencil, yet he(?) continued to jerk off to it in the euphoria of its climax.

Kyle can’t handle it any longer. The waves in his mind, body, and heart all converge on one single spot. Desperate for it to end, s(he) moaned in her enthralled voice, “Senpai, senpai! Please!”

The unreleased body of desire, holding back all of h(er)is pent-up emotions in one go.

“Ahhhh…...AHHHHH!”

And so, it was released. The thin stick is immediately dived into the growing crevasse by the end of it, bursting out liquids of white substance out of the hole. Mash recoiled from the ecstasy of the result, laying down twitching on the floor as it continues to flow out of her nethers. With it, her physical transformation to Mash Kyrielight is over.

“Huh….huh…..” Mash gasped for air. The amount of cum released sapped out the remains of her energy throughout the change. She was so tired, but the story wasn’t over yet. There is still one more thing they have to do.

With what amounted to her energy remains, she struggled to sit back on her couch, stepping on the tainted floor in the process. The mind couldn’t care and so, after much hassle, she returned to the computer screen and confronted the still-horny Mashing at the front.

“Sa….satisfied?” The new woman eagerly questioned despite the obvious fatigue in her voice.

“You could have gone further.”

“Um...yeah. What a shame.” Mash grunted. It is once in a lifetime opportunity after all. Ah…..she could have done even more suggestive poses, but what’s done is done.

“Senpai…..” she coiled herself.

‘So she’s full-on kouhai mode, huh?’ Idris though. He could tell that satisfied couldn’t describe her happiness at the thought of this mental change.

“Um-”

“Shh, shh. You still have to do the boobs.”

“Oh, right. Wait a sec.” Idris escaped his embarrassment. The thought of being called ‘Senpai’ again, now in the real world, gives him a sense of excitement unknown before. Is this what you call….

And before he even understands the sensation he’s feeling….

“Oh, don’t worry. I’ll really work hard when it happens.”

The new woman looked down at her flat chest with an eager grin. All that was left before she was fully finished was her boobs. Once they were in, then she would be perfect for her senpai. She looked at him and smiled as if she hadn’t just played with herself and creamed her pants numerous times.

“Senpai,” the young woman said eagerly.

“Don’t worry Mash, they’re coming, just need to finish writing the scenes up,” Idris said as he started the next piece. They were so close to the end and then everything would be finished. He breathed out and braced himself for the erection he was sure to come when they started coming in.

“Ohh,” the young woman said as a sudden heat formed on her chest as if someone was pressing down on it. Her nipples burned as if someone was pulling and twisting them around painfully. Her nipples quickly perked underneath her shirt, poking through it for all to see.

The young woman blushed at the sight of her nipples, but she didn’t cover them as her boobs developed. She looked at Idris with a happy smile and fought the urge to cover her developing bosom with her hands. She shivered as if she was out in the cold wearing only what she had now. The young woman gulped and looked down at her bust as it started to rise, the cloth scratching her chest from its growth. The roundness of her bust became visible and became more prominent, filling her with glee at how big she was getting. She looked at Idris and was happy to see the blush that adorned his face.

“Oh senpai,” Mash said cupping her chest as they filled the palm of her hands. Despite fitting perfectly in her hand, they continued to grow without any sign of slowing down. She knew that she would be big since that was the point of the story. She groaned as her breasts started to get mushed together and compressed against her top. It was like her shirt was acting like a lid, trying to restrain her ballooning bosom, but it was reaching its capacity.

“Oh,” the young woman groaned as it was getting harder for her to breathe. She should have been worried, but the way her breasts were getting mushed was so good. It was as if someone else was squeezing her boobs and trying to stop their growth.

RIIIIIIIIIIPPPPP!

A tear formed in the middle of her shirt and her breasts continued to balloon outward. The tear in her shirt continued to grow larger as her breasts continued swelling. The new woman moaned lustfully as they did and fondled her bust with a gleeful perverted smile that would have thrown off many since it was on Mash’s face.

“So big,” the former man said as she looked at her chest, which continued to expand. The growing lumps on her chest continued to grow and reach sizes that none would have thought possible. The tear continued to expand and her shirt got tighter around her body, which made the growth easier to see. The young woman grabbed her shirt where the tear was, her fingers brushing against her fair cleavage, making her crotch burn. Her boobs finally finished growing when they became an immense G-cup that looked like they rivaled soccer balls in terms of size.

“Senpai do you like my body?” Mash asked hopefully.

It took Idris so many distractions to make sure that his nose wasn’t bleeding, and was nearing the edge of what control he had as well. He never expected it to go this well, and for having Warden to entertain him as much as possible. Inside his heart, he felt guilty that everything has worked out in his favor so far.

“Yes, absolutely, Mash,” Idris gave out an honest, bold confession.

The words hit Mash like a direct confession from her crush. What should have been a normal confirmation, now has become one that strikes her enough she might fall off her coach. Has she emotionally become Mash as well? Ah, it comes as naturally as she breathes.

Red cheeks formed on Mash’s face as she tried her best to not like a completely lovestruck idiot in front of his fri-senpai. It’s hard enough to control her desires with such a bombastic figure, now she has to deal with the emotional state of a horny 16-year old. God, she needs a bunch of tissue after this.

“Just so you know, we’re doing the clothes, okay?” Mash bluntly speaking, giving out her best in such circumstances. Any more words and this room would have been quarantined.

“Oh, right, forgot about that,” Idris replied the same way he did earlier. The clothes for them were the most contested part since both of them had an idea of what she should wear. While Warden is on the side of a swimsuit, Mashing had proposed making it an outfit that showed off her breasts instead. Though, judging by how he normally chats around it seems that something else has caught his interest. At this point, she’s fine wearing anything since the onus is on him instead. Who knows, maybe her outfit will be as fetishistic as she thought.

Idris wrote quietly as if hiding his excitement over finalizing her transformation. And as Mash eagerly waited, she starts wondering if she was going to do the thing with him. A horny mind such as hers was suggesting various ways she can entertain her clueless Senpai and maybe gain even more from it. She wasn’t satisfied with only her fingers, she needed something else to penetrate this defenseless pussy.

CREEEAKKK

The sounds on her torn shirt began to cease. And so with it, the final changes began.

“Ahh….” Mash sat wonderstruck. Her torn shirt began to ripple and slowly contort as the fabric began to wilt in certain areas. The fabric around her arms, back, and torse quickly retreats in succession as the shirt is spread thin across her body. Before she even knew it, the fabric has melted into a black latex above her boobs, conforming to the huge knockers, dangerously on the cliff of being off-put by the smallest movement. The latex ties around her neck, giving her a chance to even move without being completely naked.

“Oh shit, Senpai. This outfit….is too skimpy!” She commented on the changing fabric. Just barely inside, she’s having the fun of having her clothes turn into this. She could feel every inch of her clothes changing its position and govern with her own. Lecherously, she began to fondle the strip of latex crossing her boobs.

“Hehe, so you chose this instead, Senpai~” Mash spoke with a tone of lewdness.

And it wasn’t the best part. Her melted fabric then went to her crotch, beginning from her waist and completely avoiding the butts. She smiled awkwardly at how the changes go. Any further below and she’s not going to survive. Especially knowing whose outfit is this, she could only hope that-

“Eep!” The new woman cried out as the latex inched over and completely covered her tainted crotch. It went so over her head she couldn’t even moan to the sensation of the latex crossing over her dirty areas. Her face darkened with a blush, an underestimation of her true feelings behind the fragile smile.

And it wasn’t the end yet. The latex, now finished its form on the body, spontaneously appear from her feet and began to stretch its way to her legs. She only watched in wonder as the black substance inches away nearer to her thighs, covering her legs in its tight, gorgeous glory. Like a slime, the way it covered her legs was far too pleasing for her to ignore and so, she eagerly fondled her new stockings with her boobs continuously hitting on her nearly-covered thighs.

The latex ended on a perfectly right amount of proportion of the thighs, only nearing her hips by a few inches away. While it doesn’t have the comfort of a bodysuit, the nearly-naked outfit can make up for its rate of lewdness. And, with the transformation finished, she can boldly say that Mash Kyrielight has finally existed as of this moment!

“Tha……thank you, Senpai! This is everything I would have wanted!” The lavender-haired girl couldn’t contain the tears of joy emanating from her eyes. A far cry from her original personality, she enjoyed every moment of this transformation and with this new ego, she wanted to enjoy every moment afterward with her beloved Senpai.

“Your welcome Mash,” Idris smiled, happy that the new girl was happy, though wished the circumstances were different.

“And thus my work is done,” BB said, wiping her hands off of the imaginary dust that she had on them.

Whatever good mood that he might had died instantly. He had forgotten about the little cyber devil with what had happened, even though she had started this. Still he wouldn’t give her the satisfaction of knowing how happy he was about this.

“Now one last thing before I take my leave,” BB said chipperly.

Idris sat up straight as his eyes bugged out, wondering what the impish little AI was up to. Considering what she had done to Warden there was little that doubt that she couldn’t do something similar or worse. Was she going to change him next, or do something else to him? Either way, he doubted that it would end well for him.

Suddenly, Idris’s face collided with a pair of soft things and he was knocked off balance. He fell back and landed on the ground. He blinked and wondered where the pair of pillows had suddenly come from. There was a heavyweight on the rest of his body as if someone was on top of him. He moved his face and grabbed one of the pillows. A loud saucy moan made him stop and shudder.

The pillows moved and he looked up to see a smiling Mashu looking down at him. She gasped in surprise and her confusion turned into a happy grin.

“Senpai!” Mash said happily.

Any sense of control that he might have had over his body was shattered and he could feel his boner standing proud. He prayed that his new little kouhai didn’t notice what was happening. He wanted nothing more than for it to go away, but he couldn’t help himself. Not with her sinful body, and what she was dressed up in.

“There we go, now that the two of you are together you can get to know each other much better. I hope the two of you enjoy your new life together!” BB said.

Somehow, Idris knew that the AI disappeared and went back to wherever she went. He looked back at his kouhai who continued to beam at him happily. She moved closer to his face with the same eager grin.

“So senpai, why don’t we get to know each other now that we’re together,” Mash said.
