A/N: Thanks to the enthusiasm of various reprehensible perverts a more proper Kuroko/MISAKA story is in the works, but as I fought writer's block last night instead of the proper story, this piece of hellspawn crack came out. Fear it!

.


Academy City's third most powerful esper had believed the worst two of her problems were respectively; the situation with her Sisters, and the constant sexual harassment from her redheaded roommate.

That was,

...until the two of them combined.

Shirai Kuroko, the infinitely lesbi-amourous and jarringly blunt-yet-polite kohai. And, Misaka 10069, just one of her numerous disarmingly ...and disturbingly literal and honest clones.

As to how they had got together she was still unsure. But together they were. Both romantically and at this very moment, geographically and, biblically too.

Now, alls fair, while it did stun her, creep her out, induced a couple of sick-in-throat incidents, and was the cause of sweat-soaked nightmares, Mikoto didn't object in principle to her stalking kohai making hot passionate love to her 'little sister', to getting all hot and bothered on a daily basis with someone only a personality transfer away from being her, to Screwing. The. Hell. Out. Of. Her. Identical. Clone. She wasn't against it in theory, yet she just couldn't help thinking it was inexcusably wrong. Regularly. Out-loud.

Earplugs had proved futile, particularly against the vibrations, sleeping tablets didn't work fast enough, and the consequences of asking her Sister if they 'could take it elsewhere' had dominated several counselling sessions.

At her wits end, and finding shocking the couple, well, counterproductive, to say the least, Mikoto switched tact and decided she would simply have to starve out Kuroko's libido. Thusly she enlisted the rest of the Misaka Network to rescue her from this secondary sexual plight, talking them, laboriously, around to her viewpoint.

Using their psychic connection they enacted what could only be described as 'the mother of all cockblocks' on 10069, preventing her from reaching climax and so trapping the couple in an eternal loop of unsatisfactory fondling. Or at least that was the plan. But weeks of sleep deprivation had eroded Mikoto's grasp on scientific basics. And like a giant e-les-trical capacitor 10069 slowly accumulated charge until even the laws of anime physics dictated she could contain no more.

"'oh oh ohhhh OHHHHH MISTRESS SHIRAI-DONO!' saayysss Miiii-saaaa-ka as sheeee cccccccc-uuuuuuuuu-mnnnn-ghjfjhgf-zzzzzzz"

The electrical explosion blacked out a 2 mile radius, left Kuroko with second degree burns on her tongue and a lifelong fear of orgasm denial play. As for Mikoto, well, her sleeping arrangement were a lot more secure, a lot lot more secure, from then on.
