Amazin-A

Let me answer this a little more appropriately. 

Basically, everything. 

Feet are just really really soft when they’re well taken care of. I love their soles, toes, wrinkles, the contour and arch, the heel, the whole form of a foot is just really arousing to me. 

That contour fits perfectly around a nice bulge too… Unf.

Apply all of that to hooves minus the toes.

Also hooves are just very big and floopy. 

Feet are floopy too. 

Like, big heavy feet and big heavy hooves.

They flop around a lot and unf I need to stop talking.
