Gilda's been gone for a couple months now. Rainbow Dash just assumed she had gone home, but the excitement-stained concrete of Fluttershy's cellar tells another story.
Once Rainbow uncovers her dark little secret, Fluttershy can't just let her leave, now can she?
Gilda needs to apologize to the pony she hurt the worst, but Fluttershy's alter ego may make that a bit harder than she thinks.
Rainbow Dash has never really experienced the whole BDSM thing, but with a little help from Gilda, Fluttershy is happy to show her. Even if she isn't exactly concerned with consent.
