Fun with swings!

A couple of Friesian horses--one male, one female--tied up, gagged and buttplugged inside of a hot barn, on a hot day with no air conditioning. At a glance, they might look like they're made out of latex given how shiny their black fur is, but that sheen is just from the sweat built up from their mating. The mare's hind legs are spread to receive the only real movement the harnesses allow; the powerful, relentless thrusting of the stallion's cock into her.

My most favorite Quillu picture of all time. I was amazed it wasn't uploaded yet, so I decided to upload it myself. Enjoy *-*

Yum! Sexy horses!
