There are a lot of perks to being close friends with Princess Twilight Sparkle. You get to nap wherever you want, you get to brag about knowing the Princess, and you can get special royalty discounts at family restaurants when they recognize your face from the paper.

But it has some drawbacks, too. You get lectured all the time about responsible flying, you're constantly pestered to provide your schedule so she can plan get-togethers, and every week or two she'll drag you off into her castle to do some homebrew magic testing, because as much as Twilight believes in the scientific method she doesn't like it when the Equestrian Magic Committee tries to directly supervise her research.

For Rainbow Dash, friendship with Princess Twilight Sparkle is a pretty good deal. She wasn't expecting to get a mind-controlling futa cock out of it, but she's looking forwards to putting it to use.

CONTAINS: Mind control, futa, loads of cum, harem-building, gangbangs, bondage, humiliation, food play, pet play, and irresponsible science.

Several chapters planned, featuring all the M6 and some extras. Commissioned by superfun!
