Submissann is well known with in the pony play circuit, she has done a bundle of photo sessions and educational events connected to the pony play scene. She has also done a bunch of videos, which mostly relate to animal role play in one way or the other.
Here is one in particular which I like as it shows one of the competitive events you can do when you are into pony play – The Blindfold Cart.
It simply means that the pony is blindfolded and has to navigate an obstacle course totally relying on the handler.
