[Draft] Sibling Shenanigans (Eirika TG) (Patreon)

Ephraim sighed as he relaxed, looking over the village and land that was lit up by the flames down below. For the first time in a long time feeling as if he could relax without worrying about something going wrong. He almost couldn’t recall how long it had been exactly. It seems like another lifetime ago that he had been fighting for his country, his people, and his friends and family to save their nation. Seeing the joy and hearing the music in the castle and the celebration from the village down below, he could tell that the future would indeed be brighter.

When the Grado Empire first invaded he didn’t think that it would lead to the adventure that it did. He had been prepared for many things, from seeing people die, places he loved getting destroyed, and losing people he cared for along the way. He had neever thought that it would lead to all of them having to fight the Demon King and sealing him away. That last battle he had never felt so terrified, but with his friends beside him he was sure that they would be able to come out the victor.

Still, he was happy for the adventure that he had with the friends he had made on the way. It might not all have been happy, but he would be lying if he said he didn’t have fun along the way. He would look back on those memories fondly for the rest of his life.

Now that the war was over the next step would be rebuilding the nation with his sister. There was so much stuff to do, that he almost wasn’t sure where to begin. The troops would need to be retrained, the land would need to be restored, the economy, and many other things. Thankfully he had his sister and many other people who would be able to help them figure it all out, and get it done.

“Brother,” a softer female voice said that made him smile.

He turned and saw his sister Eirika standing there. He saw his sister standing there in a nice white dress that complimented her natural beauty. She wore a bracelet round her wrist and a necklace that rested above her chest that complimented her beauty. She looked radiant, and for a moment he saw their mother next to her instead of her.

“I saw you leave the party, how are you feeling?” Eririka asked.

“Good,” Ephraim said. “Just taking a moment to myself for the night. It’s had to believe that it is finally over and that we can start rebuilding.”

Tomorrow their friends would be heading back to their respective countries to do their duties to their own nations. It was a sad thought, but one that he understood. If he could, he would have them all stay here so they were always close by and make more memories, but it would be selfish of him if he did. They all had their own things to do and their own people to help.

“It feels so similar to how everything was, but at the same time it’s all different,” the young man said.

“I know what you mean,” she sighed. “It feels strange to be back here after so long and what we have been through. I still remember what it had been like when we first left.”

The young man frowned, as he remembered what happened the day he left. The news when his home had been destroyed and he had been worried about his family. Every day after the news of the capital falling he had worried about what had happened to her. He was grateful for any distraction he could get no matter how small it was, but his fears would return the moment after. As if it was waiting to whisper into his ear to destroy his spirit. He had clung onto the hope that she was safe and alright. It was the only thing he could do at the time to not let himself get crushed by despair. Especially when he had his own friends nearby who needed him.

The joy that he had on seeing his sister alive had been a balm for his soul that he needed. The second time they had separated ways, it had been hard, but he wasn’t as worried. The whispers that had plagued his mind didn’t bother him as much as they had before. The simple fact of the matter was he knew that his sister would make it now, but even so as her sibling he couldn’t help but worry. She had grown stronger, and much to his joy she had emerged the victor.

“I long for the days when we were younger and everything was so simple,” Erika smiled sadly.

Ephraim smiled sadly as he thought over those days, longing for the simplicity of them. Back when they didn’t have to worry so much about and just worry about getting in trouble for running and playing around or not doing what they were supposed to.

“I understand. There’s a part of me that longs for those days too. Where we could play with each other as much as we want,” Ephraim said. “Those were fun times. I still remember that time we stole sweets from the kitchen and we got trouble in trouble because we didn’t get all the crumbs on your clothes.”

“Hey I thought that we got them all! And lets not forget there was some chocolate on your clothes to,” Eirika said.

The two shared a laugh with one another as memories of their youths started springing forth. They talked about all of the good times they had, the embarrassing memories, and even the sad ones. He was glad that it was just the two of them here. It would feel weird if someone else and heard them. Not to mention that it could lead to some teasing from some of their friends. A silence came over them that he wasn’t sure what to do next.

“You know I always wanted a sister, I didn’t care if they were all older-younger but I always fancied the thought. Sometimes I would imagine what life would be like if I had one,” his sister admitted. “The things we could do together, like playing dress-up, having cake together. Some stuff like that.”

Ephraim nodded in understanding, though it had been having another brother for him. He always wondered what it would be like to have a brother. It made him question what the relationship would be like. Would it be similar to what he had with his sister? Or would it be more in competitive nature? He hoped that they would have gotten along as well as he did with his sister.

It didn’t matter at this point. It was impossible for them to get another sibling. Their parents were dead now. They could only look to the future and grow their family with whatever partners they had in the future.

Still, that didn’t mean he could think about what it would be like to have one as well and how different things could have been. He was somewhat happy that he didn’t have to worry about another sibling during the war and something happening to them, especially another sweet little sister, or younger brother. That would have been another worry that could have broken him.

“Maybe in another life, we would have another brother and sister,” Ephraim said. “But we can’t in this one. It’s to late now.”

“Maybe we could in another life, but it isn’t too late for me to have a sister in this one,” Eirika said.

“What?” Ephraim frowned, wondering what his sister could mean by that.

The young woman raised her hand as if she was going to take his hand, however, a faint light came off of it. A pink and a purple bolt of energy flew and hit him, before he could even consider moving. He stumbled from the blow and held himself. He didn’t feel any pain, but the mere shock of it all threw him off. The young man felt off and held himself. His eyes burned and his mouth dried as if he had tried to eat a handful of sand.

“Eirika what was that? What did you do? What’s wrong with you?” Ephraim said quickly. He refused to believe that there was something wrong with his sister. There was no way she would just attack him like this.

The prince didn’t receive an answer as he noticed the faint strands of dark green hair that he could see started to brighten as if he was running hair dye through it. He watched in awe, wondering what sort of magic could do this. He tried to recall from his many royal lessons if there was any sort of magic that could cause the sort of changes like these, but he couldn't. As far as he knew there was no magic that could do any cosmetic change.

After a few seconds that seemed like hours, his hair finished changing into a bright teal color that looked like shimmering water. It took him a moment to realize that it had become the exact same shade of hair as his sister’s. He pulled as if doing so would somehow cause it to revert back to its previous, but it didn’t.

The moment it finished changing color it felt off again as if someone was pulling on it. Suddenly it’s starting to grow out as if months were passing by in minutes. He could feel each little thread of his new hair travel down his body, making him shiver as if insects were crawling down his chest. He shivered and reacted on instinct grabbing the new brighter teal licks and bunched them up. A strange unfamiliar weight that he wasn’t quite used to pulling on his head and knew it was his hair If he had a knife he would have grabbed it and used it to cut it off. His new mane of hair finished growing when it reached down his back and rested just above his butt.

The initial panic and gear that he had at the start of the transformation ceased. He forced himself to look at his sister who seemed visibly pleased from what was happening by the smile on her face. He moved closer to her, and she didn’t seem at all shocked or worried by his reaction, as if he was no threat at all.

“Ericka what is going?” Ephraim demanded, but still, he received no response from his sibling.

He glared at her, and she covered her mouth, as a small faint giggle that sounded like chimes on the wind came from her. He forced himself to remain calm, lest he find out what happened if he felt threatened or worried.

“Don’t worry brother, I’m simply getting a little sister,” Eirika said. “It’s just going to take some time before she arrives.”

“That doesn’t explain anything to me about how you are doing this,” Ephraim said.

The young woman laughed again, and again he had to restrain himself from doing something he would regret later.

He shivered as if a cold draft had come over him. The young man forced himself to remain still

He pulled back on the sleeves of his top and breathed out as he looked and saw the hair there was disappearing. Each and every little strand of hair there glowed as if had caught alight. A second after the light would vanish and the hair would vanish as if it had been burned away. He raised his leg and pulled it up to see that his leg hair was going through the same procedure. The young man breathed through his nose and tried to keep calm, but the sheer strangeness was getting to him. Which said a lot considering all that he had been through with the war.

He breathed out and pulled the front of his shirt to see if the same change was happening to his body. He could see the chest hair that was on his body was getting smaller, disappearing into a void to never be seen from again. He felt the same thing happened to his butt and the area right above his crotch and shivered at the sheer awkwardness of it all. All over his body hair was disappearing, and his body was cleaning, leaving no trace that it had been there previously.

It wasn’t just his body that was changing, to his awe, the scars on his chest that he had earned from battles were cleaning. Long jagged scars from swords, spears, axes, and magical burns were disappearing. Even marks from his childhood were disappearing. Soon his body was free of even the slightest hint of harm that had been done to it over the years.

Ephraim looked at his sister again wondering what could’ve caused this sudden change in demeanor. A small faint glow on her chest that came from a necklace they were made in blink.

“Sister where did you get that necklace?” Epriham asked, staring at the gem. The more he looked at it the more he could feel a sinister energy come off of it that felt painstakingly familiar.

“Do you like it? I think it looks marvelous on me,” Erica said. She reached up and rubbed a gemstone on it which glowed a little brighter at hertouch.

The young man gulped willing to bet that was the reason why his sister was acting like someone else entirely.

I think you would look better without it. Why don't you take it off so we can talk about things? Besides you don't need something like that,” Ephraim said, hopimg hismsitet would agree to it.

“I don’t think so brother,” his sister said. “I quite like the way it looks on me. It would be a shame to take it off, especially since it helps complete my outfit.”

The young man held back a sigh. He had hoped that he wouldn't have to hurt his sister, but it might be the only way to save her. There was also what the spell might do to him. Maybe if he helped his sister get back to normal before it finished what it was doing then he could turn back to normal.

He leaped forward but she moved, faster then she should have been able to. He tried again to grab her, but she avoided him again, letting out a giggle as she did. Her movements were too fast, too precise to be natural. His sister’s skills with a blade had grown immensely after all that had happened, but the speed now was faster. A laugh escaped her lips, as if she was playing a game of tag just like when they were children. His hand brushed against her arm, but he couldn't grab her. For a moment, a smile formed on his face and he thought he might be able to stop this and save his sister. To his horror, the gem glowed brighter and she snapped her fingers as if it was a signal.

The prince groaned again and his arms suddenly felt heavier, as if large iron chains had been wrapped around his body. He could feel the change hit his arms. The hard muscles that he had get smaller as if age was taking them. The young man gulped as his clothes started to feel more off against his now softer skin. The former material roughly rubbed against his skin and for a moment made him want to tear it off and throw them to the side, embarrassment be damned. It continued to get worse and it was only his finely edged self-control that prevented him from giving into his baser urge.

The same power that was working his body is starting to affect his legs. His toes started to get smaller along with the rest of his feet, his leather shoes now feeling like they were several sizes too large. The changes then stop at his feet but continued up his legs, making him shiver. Felt felt like he was sinking into the ground.

When the changes reached his thighs they started to grow larger as if the lost height and muscle was returning on his body down there. He blushed at the pleasing sensation of the soft flesh building there. Despite his best efforts to ignore, his lips quivered and his hands involuntarily curled. They finished growing when they became strong feminine thighs that would have been something to gaze upon.

The young man flushed at feeling his sword rub against his femine thighs. He grabbed the he, of his trousers and tried to adjust them as best he could, but the feeling of his new soft thighs made it hard to ignore. Thoughts of being with the woman he loved filled his head and his blush darkened further. He tried to adjust his pants so his masculinity wasn’t rubbing against his thighs as much, but there was nothing he could do about it with how loose his clothing was. All he managed to do was have it rest against his other thigh.

“Don’t be so rude brother, everything will be alright soon,” Eirika said, her voice gaining a slight echo to it, as if she was speaking through a tube. “Just let the rest of the transformation happen of its own will. Once it's all over then we can have all sorts of fun together. There are so many things we can do together when its done that I can’t wait.”

The young man frowned heavily, scowling at his sister. He had no idea what all those plans were and to be frank he didn’t want to find out. The only thing he had to do right now was to save his sister from the influence of that necklace before it reached a point of no return.

The prince moved to tackle her, but she raised her hand and he rose up in the air as if he was a child being lifted up in the air by a parent. With a wave of her hand he flew into the wall and stayed there. It was as if rope had been wrapped around his waist and two strong men were holding him in place. He tried to move his limbs off of it, but despite his best efforts they stayed put, as if they refused to move.

“Let’s put you up against the wall for now,” the princess said. “Just until you have calmed down a little. It would be bad if anyone saw you lashing out and attacking your younger sister.”

“Sister stop this please!” He pleaded. “Whatever is happening to you we can defeat it. Let me help you!”

She frowned, and for a moment he thought that his words might have gotten through to her.

She lowered her head, as if she couldn’t look at him for a moment. He smiled gently at her, praying that he had finally reached her.

She looked up at him with a smile that promised that everything would be ok, but all it did was send a needle of ice through his spine that made him gulp.

“I’m sorry that we need to take some extra steps before we can finish, but it's for your own good,” Eirika said with a patient disarming smile that would have caused many to relax on a moment’s notice. “We will continue on with the next part.”

“Ahh,” the changing prince cried as he could feel his stomach start to change. The hard abs that he had gained from years of training and discipline started to recede into his body. The changing prince felt like a rock was grinding against his stomach and shivered as he did. He tried to move his stomach as best he could, but sucked in his gut as if it would. It wasn’t a surprise to him that it didn’t work, but he had hoped that it would at least slow it down. The grinding against his stomach started to slow and grow less intense as if the stone they were using to do so was getting dull. It soon came to an end, much to his relief.

Ephraim didn’t have too long to ponder the change as his waist started to curve inward. He groaned as if he was being held in a tight bear hug that was crushing him. His first instinct was to reach down and try to get the ‘hugger’ to stop, but with how restrained his arms was he couldn’t do anything about it.

Another groan left his mouth and he could feel his waist start to curve. There was nothing he could do, as it got worse. It was almost pleasing, as if he was being bundled up in many furs. He was intimately aware of the centimeters that were disappearing off of his frame. His curiosity got the better of him and he looked down and watched the changes happen with a heavy frown. Even if he wasn’t watching he could feel the changes. Numerous swears entered his mind that he couldn’t bring himself to say for his sister’s sake. It wasn’t her fault, it was the gem’s fault. He would deal with it when it was over.

When the changes stopped he let out a sigh of relief, happy that it had stopped. He examined his new waist, and while it wasn’t on perfect display he could still tell how much it had changed. From how his shirt was draped on the sides of his body he knew he had a slim waist that was comparable to his sister. With how it was over his stomach he could tell that he had a slim stomach as well.

“You can feel your stomach if you want. It is your body after all,” laughed.

The pressure on his arms ceased and he quickly curled his fingers and moved his hands to test it. To his relief all of the struggle that he had mere moments ago was gone. He didn’t say anything lest his sister make his situation even worse than it already was.

Eprhaim sighed as he slowly moved his hands, testing the range of motion that he had. He pressed down on his new stomach and frowned at how different it was. There was still a tightness and strength much to his relief, but it wasn’t as prominent. It was small, but he took some solace from the fact that he didn’t have a pudgy gut. It would have been a challenge if he had to train to earn all of that muscle back after so many years of practice.

“Don’t you like your new flat stomach? It feels nice doesn't it,” his possessed sister giggled.

The changing young man held back the words that wanted to escape his mouth. It most certainly didn’t feel nice. It was strange, awkward and if he had to keep it, he doubted that he would ever get used to it.

“Oh you don’t have to be so silent. I know it is a big change, but I’m sure that you will grow to like it when it is over.”

“Sister the fact you did this without my consent is a sign that something is wrong?” Ephraim said.

“You'll thank me when it's all done,” Eirika shrugged. She stepped forward as the invisible chains that held his limbs strengthened. She stopped in front of him and her smile grew as she gently cupped his face. She tubbed

“Now then we can start with one of the most impactful changes,” his sister said.

She gently massaged his face as if she was examining a priceless gem or weapon as her hands glowed again. He gasped as the sudden sensation of his face being dunked underwater came over him. She pulled at his cheeks as if she was teasing a small child. He glared at her despite the changes. She rubbed her head, her soft hair brushing against his nose. His nose twitched and

“Eirika stop this please!” Eprhaim pleaded.

“Shh, relax,” Eirika instructed gently as she pinched his lips with one hand. With the other she continued to rub his face. The young man could feel his lips swell against her slim digits.

His face softened from the brushing locks and the massaging hands.

His nose continued to twitch he wanted

He sneeze

“Bless you,” Eirika said. “Let me help you with this real quick.”

She pinched the bridge of his and it started to get smaller against her fingers.

He tried to turn his head, but it was as if he was held in a vice grip and people were forcing him to face forward.

“And one more thing before I forget,” she said.

She gently grabbed his throat, his throat tingling. He winced from the sound that left it, and the oddness of her holding her throat. A small lighter growl involuntarily escaped his mouth. Every little grunt that escaped came out was a little higher than it had been moments before. It reached a point where his mouth opened and a soft feminine gasp came out that sounded painstakingly familiar to the young man.

“There we go, all done,” Eirika clapped happily.

Eirika pulled off one of her bracelets and with the same magic had transformed it into a mirror. She angled it up so that he could see

He gasped at the sight of the face looking back. Instead of his own visage looked back at him, the face was that of his sister’s.

“Sister this is your face,” Ephraim said.

“True, but now it is also your’s,” she giggled.

He had a suspicion with the color of his hair, but this only confirmed his worst fears about what was happening.

“You’re almost done, and now it is time for you to enter womanhood properly,” Eirika squealed happily, as if she had received a gift that she always wanted.

“Eirika stop this! It isn’t to late to go back

“It isn’t, but I want a little sister, is that a bad thing?” his possessed sister said. “Now don’t worry I’m not going to make this awkward by touching them or anything.”

Before he could say anything, he squealed as his balls felt like

The young man squealed as he could feel the power work on his masculinity, as if a belt was over it.

“And now I really do have a little sister,” Eirika squealed happily.

All the restraints that were on the former prince’s body suddenly let loose and she could fall down the wall freely. The young woman stumbled, but didn’t have a moment to think it over as she was tackled by her sibling who was smiling happily an hugging her.

“Just a couple of things that need to be changed and then we’re done,” she said and started to roam her body. “I think taking care of your girls down below would be preferable.”

Ephraim’s butt grew against her hands, filling with muscle that made her squirm. A blush adorned Ephriam’s face from the assault of her younger sister. She vaguely noticed that her sibling’s hand was moving closer to the crack of her bum. The new woman clenched her bottom cheeks as tight as she could to prevent her sibling from doing anything naughtier than she already was. The growth of her posterior ceased despite the rubbing to her bottom and it had become a cute toned butt that would have aught quite the attention if they were in more form-fitting pants.

“Oh your butt really is nice, just like mine,” Eirika said as she continued to massage her sister’s rear through her pants.

“Eirika!” Ephraim said with a dark blush. “Stop it!”

“Oh fine you party pooper,” Eirika said. “Besides its about time we get to the climax of this.”

For a moment, Ephraim had no idea what she was talking about, until her sister pushed, and her sister’s

“Sister please no, I don’t want...breasts,” Ephraim said as she could feel her nipples erect under her top.

“Don’t worry it will be fine,” Eirika. “Just relax and enjoy yourself.

The new girls blushed heavily and mewled as her chest started to push out and gulped as it did. She squirmed trying to break away from her sister before. She breathed heavily through her nose as her nipples rubbed against the front of her rougher cloth. Two small lumps formed underneath and started to grow larger. She moaned as they swelled in size, rubbing against the confines of her clothes and making her quiver. They finished growing when they became a healthy C-cup the size of oranges.

“There we go sister,” the original woman said and hugged her new twin sister with a happy smile, forcing her twin’s arms at her sides.

Ephraim continued to struggle in her twin’s arm, but was unable to escape.

“Oh your so perfect little sister!” Eirika cried as she snuggled with renewed vigor. She stopped and frowned at the sight of her sibling’s clothes. “Oh you can’t keep wearing those rags sister. We need to get you in something more fitting for you.”

The clothes that she wore started to merge together. The dark green color of his top started to fade away and brighten.The lowest section of it merged with the top of her pants, as if it was one large article of clothing. The legs of his pants merged together, forcing her now plush thighs together, making her gasp in surprise. The sudden tightness didnt last long as the bottom half suddenly grew out. Frills formed around it and wrapped around her body ,giving it  more extravagant look. Gone was her formal dark green top and nice black pants. In their place was an extravagant white dress with ruffles and heemings that highlighted her beauty.

The new princess looked down at her clothes with a dark embarrassed blush. She had never wore these kinds of clothes before and it felt strangely right. Her clothes didn’t bother her and gently draped over her body, highlighting her soft feminine curves.

“Oh your just perfect!” Eirika squealed. “Better than I could have hoped.”

Eirike pulled her again into a hug. The necklace touched Ephraim’s chest  and another shock went through her that made her gasp. The cloud in her mind worsed and she shivered.

“Just relax it will soon be over.”

The changed young man tried desperately to fight the mental onslaught, but it was getting harder by the second. She focused more on her past, and all the happy times. The new memories grew in strength, and she desperately clung to them. New memories of events of her new body came to her and she pushed them away as best she could, but they swelled in number. The memories of the life she had was getting overwhelmed and subverted. Suddenly she had been overwhelmed and her mouth dropped.

“Beautiful,” Ephraim said in a muttered haze.

“Exactly sister, you’re beautiful,” Eirika said happily and nuzzled her face. “Now why don’t we go back to the party.”

The two new sisters went back to the party. It would look odd if the two princesses weren't there for to long. Besides this was a party and they were going to have to have fun before they had to get to work on fixing their home.
