Let's check out the mirror first

There was a really huge mirror inside the bedroom, that really stood out. Naturally, Kanami did the only rational thing and posed in front of it.

“Ehehehehe! I guess I am pretty cool, huh?”

”⸮ʜυʜ ,looɔ γɈɈɘɿq mɒ I ƨƨɘυϱ I !ɘʜɘʜɘʜɘʜƎ“

Kanami made a peace sign at the mirror. “Extremely competent Ninja, Kanami is here!”

”!ɘɿɘʜ ƨi imɒnɒﻼ ,ɒįniИ ɈnɘɈɘqmoɔ γlɘmɘɿɈxƎ“

Kanami paused. Something was odd here. It took her a bit as her razor sharp mind connected the dots.

“Mirrors don't talk!”

”!ʞlɒɈ Ɉ'nob ƨɿoɿɿiM“

Ok, this was getting rather freaky here! Kanami gazed at her reflection.

This was definitely her body and her underwear. With froggy print and all. But something felt off. Perhaps the fact that her reflection was waving at her.

“Gyaahhh!”

Kanami's reflection(?) apologetically waved her hands and then put her ring-finger towards her lips.

"ɘm qlɘʜ ɘƨɒɘlԳ"

“Uh what? Can you speak normally, please? This is kinda getting annoying.”

“Please help me. I was imprisoned by the Devil Atlanta. I need you to get me out of here.”

Kanami remembered that Freya once told her about that particular Devil. Apparently that one liked to imprison girls in mirrors for all eternity. But the worst part of it all was that they where all in their underwear when it happens! Kanami couldn't even fathom how embarrassing that must be.

“Sometimes, you find a shard of them as rare monster drop. The usually fetch a pretty good price”, Freya used to say.

But this wasn't a shard, this was hundreds of shards! A whole mirror worth of shards!

Kanami couldn't believe her luck! Not only did she win a mansion! She also found a mirror-girl inside. She can sell this to some pervert and make hundreds of gold coins out of it!

“Umm..you are going to help me, right?”, asked Mirror-Kanami with a frown on her face.

“Why would I do that?”, replied Not-Mirror-Kanami.

That seemed to take Mirror-Kanami a bit aback. “Because, it is the right thing to do? You are a good person, right?”

Of course Kanami was a good person. As long as no money was involved.

“Look I get it, sucks to be you that you are stuck in a mirror, but that's not my problem. Maybe the rich, evil pervert I sell you to will release you?” Kanami shrugged.

“Do you wish for money? I have a vast fortune! If you free me you will get thousands of gold coins!”

Kaching!

Kanami couldn't wait until she get to see Freya again! Freya will be green from envy! Actually, Kanami will be so rich she can just buy Freya! Then Freya will be the one dancing on tables!

Giddy with excitement the ninja grinned. “Ehehehe! Of course I will help you! What do I have to do?”

Mirror-Kanami let out a sigh of relief at that. “I thank you from the bottom of my heart. It is simple really, all you have to do is come closer and kiss me.”

Ugh, things can never be easy with these Devils, huh? Oh well, Kanami already made out with a Kalar queen. She can surely kiss a dingy old mirror.

And so Kanami inched closer, placed her hands on the mirror and put a chaste kiss on her reflection.

Only that kiss wasn't chaste for long. With a bit of panic Kanami realized that her tongue was slipping inside her mirrored self. That should not be possible, but the ninja didn't have much time contemplating that as her tongue was quickly welcomed by another. Well, her own technically? Wow, this was weird!

Then, a large lightning strike occurred and for a few moments all Kanami could do was blink in confusion.

"⸮ʜυʜ"

There was mirror-Kanami, but she was still on the other side.

"⸮ʞɿow Ɉon Ɉi biႧ"

“Oh, it did work alright. It worked splendidly.” Mirror-Kanami was now grinning wildly, all pretenses of her former timid self gone.

"!ɘm bɘʞɔiɿɈ υoY"

“You can say that again. I was imprisoned in that cursed mirror for two millennia! All this time waiting until a gullible fool came along to trade place with me.”

"!ɘm ʜɈiw ʞɔɒd ɘbɒɿT"

Mirror-Kanami laughed haughtily at that. “I don't think so. As it happens I quite like this body.” She gave herself a slap on the butt. “Not as good as my old one, but it will suffice.”

Kanami felt a sharp pain. To her horror, her own body mimicked her actions!

“Oh yes, you better get used to that”, explained Mirror-Kanami. “Aside from speech, your body will pretty much mimic every person that comes in front of the mirror. With time you can fight it bur now...” Mirror-Kanami squeezed her breasts. “Not a chance.”

"!Ɉi qoɈƨ-Ƨ"

Not even her curse was working! Mirror-Kanami merely chuckled and walked over to the bed. “If you would have helped me nicely, I would have left you alone as a reward. But you had to be a greedy fool about it, didn't you? I think a bit of punishment is in order for this insolence.”

Mirror-Kanami stretched herself on the bed and slowly let her hand slip into her panties. “Hmm, very sensitive, I like it.”

Kanami didn't like it at all! But no matter how hard she tried there was nothing she could do as her body mimicked the movements. It didn't help that her mirror-self was actually really good at it! So good in fact that Kanami was brought close to climax after just a bit of touching.

“Now, now, let's not get too hasty.” Mirror-Kanami chuckled and slowed her caressing just a tad.

Kanami let out a soft whine at that. Her evil self was in full control and seemed to know everything about her. Soon enough the desire to cum was unbearable.

Mirror-Kanami gently traced the outside of her vagina, teasing her to an insane degree. “Beg me to cum, slut.”

“!ɿɘvɘn-И”

Kanami will never give in!

Her evil self let out a chuckle. “Fool, I love to dominate girls like you. I can do this all night.” One hand shut upwards towards Kanami's boobs and started to fondle herself. Kanami inhaled sharply at that.

Kanami decided to give in.

”.mυɔ...ɘm Ɉɘl ɘƨɒɘlq-Գ“

“Oh, please. That hardly counts as begging.”

Ugh!

”.mɒ I ,Ɉυlƨ ɘʜɈ ɘʞil mυɔ ɘm Ɉɘ⅃ .Ɉnɒw υoγ ϱniʜɈγnɒ ob I...I...ɘƨɒɘlq...υoγ ϱɘd....I....mυɔ ɘm Ɉɘl..ɘƨɒɘlq γɈɈɘɿԳ“

Mirror-Kanami seemed to genuinely consider it for a moment, then she intensified her movement once again, bringing Kanami just completely to the edge, before abruptly halting again.

“No.”

"!TAHW"

Instead Mirror-Kanami got up from the bed and stretched herself. “I think I much prefer you to go mad with frustration.”

"!ooɈ γnɿoʜ ɘd lliw υoγ Ɉυઘ"

“I am quite accustomed to this feeling. Besides I will soon have someone to alleviate this.”

Wow, Kanami never hated herself more then right now.

“Now then, I have places to go and things to do. Enjoy your stay her, girl.” Mirror-Kanami flipped her hair and walked out of the frame. Kanami followed for a bit, before she hit the edge of the mirror and was unable to move.

This could be bad.
