Original Description:
 
Repost from my private gallery.  
I wanted to post it on deviantart and register there but i did find terns of use unclear. It’s a complicated topic and I shouldn’t use englisch but here we are.  
What is an original artwork?  
Characters look is based on two famous alicorns. Colors and shapes…that thing with colory lines; The idea of naughty sisters isnt new; I drew by en example of “licking” and “sweating uncomfortably”. What is really originally mine here?
