I know there is plenty of “kinkPies” already (search it).  
But with my Pie I gave her some distinction which shoud make her look different from being just a perv version of Pinkie Pie.
 
Kinky Pie is Pinkie’s cousin in the fourth degree.  
She lives in VanHoover.  
They look almost the same expect tone of the their fur and mane is reversed, when Pinkie’s fur is lighter then her mane Kinky’s mane is lighter than her fur.  
And her cutie mark shows one air balloon instead of three like on Pinkie’s flank.  
Kinkie’s CM symbolise here kinky/fetish nature (the balloon represents ‘balloon fetish’ but it actually about sexual fetichism in general).  
Also, Kinky is open Pansexual, which makes her life is a bit complex.
 
Not sure wha to do with this character.  
Maybe I will come back to her or she will stay as a simple doodle in my gallery.
 
P.S. If you find her colors simular to Scootaloo’s, yes, I notesed it too. I just was slacking with colors.
