Flash Sentry probably has the most boring post in the world: being the only Royal Guard for the Princess of Friendship in her own castle. Plus, she's a magical powerhouse who's defeated every major baddie Flash has ever heard about.

It's enough to give a guy an inferiority complex. And some fantasies. Fantasies that one Twilight Sparkle is more than happy to exploit!

Spoiler Contents: this story contains: really erotic dreams, getting caught having really erotic dreams, plenty of sexplay between Flash and Twilight, bimbofication, turning into a sex doll, seduction, corruption, mind control, super sexy MTF transformations, turning a straight stallion bi, living latex and being plugged into a magical dimension of pure sexual experience and bliss~!
