Part Three – Well my pony slut has managed to complete this training session, and Im not satisfied with his progress. However, I have decided to allow him a reward to give him some incentive for his next session. I have him on a tight leash kneeling at my feet. His throbbing cock is under my boot, and as I tug on his leash I tell him to use that tongue of his to get licking. As I increase the pressure of my boot on his cock, he groans and gets more excited. Of course he cant cum until I tell him. Finally I give the slut permission to cum. As my boot crushes his cock, he squirts out on my throne. The filthy slut will have to lick up his mess, and finish cleaning my boots before I return him to his cage…
