Questionable Questing

Anything involving the sisters would be some crazy deadpan porn narration, though. Could be fun, but I can't see Mikoto being into it, if only because she can't be that honest. ^_^;

KokoroXMikoto Sisters then? Her dream come true

Hmm... if Kuroko knew that it wasn't Mikoto from the start she might actually display a bit of restraint, despite Mikoto's fears to the contrary. If she warmed to the idea though i could see her being turned on by the no-affect passive aggressive verbal abuse that the sisters would probably be heaping on her.

Maso

Indeed, though I could also see having her "onee-sama" at her mercy, if only in appearance, would be enticing. It does come down to how Kuroko is Mikoto-sexual, so if it's not actually Mikoto then anything they do is going to be compared to Mikoto in her head. Without the intent to write porn that disregards character agency i could see writing Kuroko x Sisters porn requiring some decent justification.

Mistaken identity and Koroko going way to far way to fast for an non-resisting Sister. Then of course, Mikoto steps in and kicks her ass as usual.

Hmm... to avoid kinks that aren't my thing, i would probably frame it as Kuroko knowing that it's not Mikoto and the sister trying to not be found out while Kuroko makes absurd insinuations about her and Mikoto's relationship to try and break the impostor's mask. If Kuroko insists that her and Mikoto do this and that all the time it can be a game of chicken until Mikoto intervenes.

"'Of course I am Misaka,' Misaka states confidently." Misaka-Imouto states confidently at the skeptical Kuroko.

"While loath am I to entertain the idea that anyone might hope to approach the magnificence of my Onee-sama, I must admit that I remain skeptical. My Onee-sama would never be so cold as to shrink from my welcoming embrace here in the sanctity of our dormitory, away from the judging eyes of the masses."

<Mikoto silently fumes under the bed as the Sister reluctantly lets Kuroko gleefully motorboat her and grab her butt>

"'While this action does not seem uncomfortable, Misaka is unsure how long Misaka is to stay still,' Misaka says questioningly," Misaka-Imouto says questioningly.

Given the Misaka Sister's trollish humour, I think they would be more likely to try to fuck with Kuroko by insinuating they are going on a date.

Or saying they are Misaka's evil sister before giving a deadpan muahaha!^^

Edit: Btw. the super skimpy swimsuits are part of the main novels, Touma gets dragged into a shopping trip once where they have one turns from a normal to a string bikini at a touch.

Hmm... It they are trying to not break cover and uncertain that they have fooled Kuroko i am not sure it is the moment for trolling. However, an alternate outcome to Kuroko trying to get some skinship with the excuse that they are all alone might indeed be to stop being alone with her immediately.

If Kuroko correctly assumes that she is running away, taking Kuroko with her on a "date" with plans to run away later is probably an acceptable alternative.

Also, i am not surprised by the broader canonicity of the swimsuits; i was never under the illusion that fanservice was a rare thing in the novels, what with some of the index character designs. ^_^;

One thing to note is that the clones have a distinct lack of common sense and zero sense of shame. i.e. one stripped in public when Touma commented about her panties working as a way to distinguish her form the original.

They may actually cause Kuroko to faint in shock when they start recopricating her "friendly skinship" thinking it is expected.

Hmm... If they actually already have that data point then Kuroko trying to touch her butt might put her guard up if only because she does know that panties can be used as an identifier somehow. In fact, she might assume that examining her panties was Kuroko's whole intent with the skinship, which could lead to trying to find valid excuses to get out of it.

Comedic frustration at thwarted sexytimes might be fuel to make Kuroko even more persistent on their "date," to the point that she starts to forget that she's actually trying to out an imposter.

There is also of course the option that the Sister brilliantly deduces that if her panties can out her and Kuroko keeps going for them then the panties must go, so she ditches them at some point on the date. Kuroko trying to cope with public nopan "Mikoto" can only be comedy gold no matter how it works out.

I could see that happening, the sister discreetly excusing herself to the toilet and throwing the panties in the trash. Then when Kuroko is stumped she gets a monotone "Oh no, I forgot to put them on in the morning"

Heh, I could actually see that being adopted by the other sisters still in Academy City since they have the highest chance to run into people Misaka knows.

Honestly, I am tempted to write something like this, if only for some oneshots... sort of like that short-series where Touma ended up in a porn movie.
