The Reluctant Pony

"You think being a pony girl only involves prancing around in an outfit and hooved boots, looking pretty? Boy, are you wrong! A pony girl does whatever her handler tells her to do, or she gets the crop across her ass.
Well I'm your handler and I'm telling you to get down on your knees so I can unzip and see if that tongue of yours is good for anything other than whining."
