So I normally never draw lewd and slutty clothing for anyone, but Fluttegoth made me bring an acception to this since I believe she does it well as a goth.
 
Fluttershy has invited you as a fellow Equestrian to her house to “help out” with something. Little do you know that it’s all an imminent setup. You arrive in the evening according to the time she needed you, you knock on her door, the door opens slowly, you walk in and it closes behind you and locks all Resident Evil or Scooby-Doo style.
 
You call her name as you walk upstairs to her room. You slowly open the door and see her dressed in lewd attire as Fluttergoth. The goth pegasus goads you into her room. You walk in the the door behind you closes and locks as well. Trapped in her bedroom as she planned you cannot leave until you perform a Flutter Ritual. The ritual involves her grabbing you and wrapping her large spike belt around both you and her and smothering you with her breast afterwards and starts suffocating you with them. Fluttershy’s goal was to be able to change to Flutterbat at will instead of by random chance so she can gain vampiric powers and abilities.
 
She keeps your face trapped between her breast until you black out. You later wake up on her hed where she pours tomato sauce on you because even though this is Fluttergoth, she’s still the scared and shy yellow pegasus deep inside so yeah she used tomato sauce instead of real blood cause she’s scared to use it. She licks it off of your body and starts smooching you. The magical dark energy rises in her room as it enters her, finally she can turn into a bat pony anytime…..or so it would have happened if it weren’t for one fact she ignored. She’s just too nice. Fluttershy can pull off the goth personality very well (Fluttergoth is best) and show it to everyone, but deep down she generally was never just the dark type as the dark energy saw in her heart that one shred of kindness and light that would never leave. That was the obstacle. She gets mad, unties you, unlocks all doors, and angrily says “Leave! It was a failure so get out!…..if you don’t mind.”
