You Will Be My Pony

Down on your knees with you! Mistress Mercedes wants to rail. How fortunate that her little pony is such a subjugated man, willing to be used by her the way she wants it. Mercedes very much likes railing her pony, but she is angry because the pony cant trot as swift and as persistent as she would like it to and requests. Well, then, she is dealing out blows to get it going!
