我的继坶我的性老师

Kat planted herself face first into the sheets and let out a groan. It was nearly dinner time on Friday night and Kat still hadn\'t managed to hide her wings. Kat wasn\'t even sure if it was possible anymore. Kat found that while she could move the water around, it didn\'t like to leave it\'s predetermined shape, and would snap back into place before long. Perhaps it was a safety mechanism, or just her mind worrying too much and preventing it from working as Kat willed it… but Kat was now all but certain she had failed. "I can\'t do it. I\'m not going to make it in time. I guess I have to talk to Sylvie and Callisto now," mumbled Kat. 

Kat didn\'t see the look of glee on Lily\'s face that was hidden a moment later, undetected due to the link still being closed. Kat had been trying to vanish her torso today, and succeeded… but her organs remained as organs and it was freaky to see. It didn\'t feel great either, very weird, especially around the lungs and stomach. So Lily had asked for the link to temporarily be blocked again. 

Trying her best to sound saddened by the news, and not excited to see Kat\'s reaction in a few minutes Lily said, "That\'s a shame, but I\'m sure Callisto and Sylvie will understand, or maybe they have a plan? I mean, they\'re pretty smart right?" Lily hadn\'t been able to resist giving Kat a bit of a hint…

"I guess I\'ll go see them… but I don\'t see how they would have a solution. Surely they\'d have mentioned it to me before right?" asked Kat, completely missing Lily\'s hint. Kat sighed once again into the mattress before pulling herself up and walking to Callisto\'s room. She could here Sylvie and Callisto on the other side of the door, but intentionally ignored what they were saying. Kat took a deep breath and knocked on the door. 

"Come in!" yelled Callisto. It wasn\'t strictly necessary, Kat\'s hearing was good enough for the door to be a minor issue now she was in front of it, but even Callisto was prone to habits such as this. 

Kat smiled and walked in, shocked by what she saw. Much of Callisto\'s usually tidy workspace was taken up by large posters and diagrams clearly for the science fair tomorrow. What surprised Kat, was the contents. It seemed that Sylvie had done the math, and biology researched, required to answer the question \'What if humans had wings\'. It was tackled from a few different angles with drawings representing the possibilities. 

What really drew Kat\'s attention though, was the device Sylvie had just stepped away from. Callisto was watching it all go together, but it was clear Sylvie had done most of the work, if only due to the oversized leather apron on Sylvie\'s front combined with various debris that had ended up on the small girl during her work. And what a work it was. 

Kat could see a slightly scaled up replica of her own wings sitting there on a stand. The leather on them had clearly been painted black, and the wings themselves were slightly larger then Kat\'s own, but the craftsmanship was well done. The metal supports were still clearly visible, but that didn\'t take away from the effort it took to make something like this. Their was a harness that went around the chest, arms and legs, likely to help the wearer distribute the weight evenly. It looked, to Kat at least, that Sylvie had taken her wings and try to make a copy of them… but why…

*Oh! Oh Sylvie you darling. You planned this the whole time! Why did you guys let me waste my time trying to come up with a solution when Sylvie was already twelve steps ahead and baked one into her entire project!*

"Those are for me aren\'t they?" asked Kat in a whisper. 

"Yup," said Sylvie happily. "I\'ve got my own set… but Callisto made those so technically I can\'t take them to the science fair and show them off as my work… but she used them as a guide, and I just had to follow step by step to build my own set for you!" 

Kat pulled Sylvie into a hug, disregarding the metal shavings and leather paint that was rubbing against her. She was a succubus, it wasn\'t an issue for her skin and her clothes could be resummoned. "So these fit over my wings?" asked Kat as she caught up to what was going on. 

"Yup," said Sylvie easily. "It took a lot of designing, but they work both over your wings, or someone else can put them on. The plan was, if you didn\'t make it back in time, for Vivian to wear them. They\'re a bit heavier then we planned though… and I am not entirely sure that Vivian could wear them long without issues…" 

"But of course that\'s no problem for me," continued Kat as she caught up to what Sylvie was saying. "They need to look \'real\', well, for a given definition of real. It needs to look like you made the wings, and they need to be worn by anyone and still work. Well, technically they need to only look like they should work… but I guess you both wanted to go overboard?" 

"It just was not worth the risk," said Callisto. "It is entirely possible that one of the judges would know enough about the construction of something like this to notice the impossibility if we only touched up the outward appearance. It took quite a few design variations but we were eventually able to settle on wings that look like this. In fact, designing wings with leather helped remind us that while typically we assume winged humans would have feathers, we are in fact more closely related to bats. It helped refine the other models and give us an excuse to take the demonic angle,"

"Yeah," said Sylvie with a smile. "Sadly we still can\'t say that you\'ve got a copy of working wings, that would be silly, but the model you\'ll be wearing… well… if you still want to go…" Kat gave Sylvie a look that conveyed how ridiculous that question was. "Right, well, we\'re using you to show that scientifically speaking, demons are far more likely to exist then angels, and you\'re our demon example. The wings will still be too heavy to fly, and despite the fact I know you CAN fly, we can\'t publish that sort of thing. The math doesn\'t check out," 

"Right… but angles ALSO exist," pointed out Kat. 

"True but most people think demons do not exist either so the precise truth of the matter isn\'t something we should worry about. Plus… do we know that angels even look like angels? Not all demons look like demons we think of after all. Do angels even have wings? We just do not know," said Sylvie. 

"I can\'t say… even the angel I \'met\' wasn\'t actually around at the time. Perhaps they do? I know they sound fucking weird," said Kat. 

"Indeed. As we have no proof of either, I have decided to pretend that I simply believe what the rest of the scientific community do. At least for this project. I would rather not be responsible for a complete overturning of what we know to be true, and I certainly have no desire for the attention that sort of revelation would gather," said Sylvie. 

"Yes that would be a bit much. Perhaps when you\'re older such a paper and proof might be worth publishing," said Callisto. 

"I wouldn\'t want to make things hard for Kat though…" said Sylvie. 

"It\'s not something I\'m worried about right now," said Kat. "I\'d be more concerned for you all anyway. I can survive whatever they throw at me, but you\'re all still squishy humans," 

Kat\'s mouth twitched into a smirk as she snuck her hands around Sylvie\'s apron and started to tickle the little girl. Kat delighted in the laughter she was able to gather from Sylvie, catching the young girl before she hit the ground when her legs gave out. Callisto stood off to the side, a hand covering her own amused smile. 

When Sylvie finally recovered, she said, "I\'ll just have to become stronger! If Callisto and Vivian don\'t want it I can use that token of yours and become strong!" 

Callisto shrugged, "I have no desire to outlive Vivian or you, I would not take first dibs on the token," 

Sylvie frowned at the idea, "I don\'t want you or Vivian to die though… and you\'re older than me… perhaps you should take it first?" 

Callisto shrugged, "Perhaps, but we know such treatments can be purchased, even if they will not raise us up to the extent of Lily\'s power. If Kat desires to keep us all around, she can find a way I\'m sure," 

Kat smiled, though her eyes held some sadness, "Not everyone I\'m afraid. I already made the offer to Gramps after all, but he turned me down," Callisto and Sylvie nodded in understanding. Gramps and his wife were well enough know that the answer was obvious to both.
