i'm not a 'Brony' by any stretch but i do really enjoy the most recent My Little Pony, and Rarity is my favorite character. This comic came up because i was asked (i can't remember whom by) if i were to have relations with one of the ponies which would i pick. So yeah i have some weird gross friends, WHICH IS AWESOME!!
Also as a huge disclaimer: I did not draw that background it was created by the wonderful artists that create MLP. and resourced from one of the many MLP wikis. Thanks to both!
