You mind reels at the sight of a face which would be perfect for a Mule. The terrible exception is that you weren't a Mule, but now had the head of one.
Long ears covered in dark brown fur have light gray hairs covering their insides. A creast of the black stubby mane peaks between the ears and as you turn a little the mane and a broadened neck run down into your shirt.
Big round, dark eyes look into the trough. You blink big eyelids just to check if they really belong to your face, they do! Your nose and mouth are grown together reaching out as the muzzel and face of this Mule head.
Snorting your breath make the nostils open wider and flare. A mealy gray muzzel hairs give the final adding to your degraded face. As lips feel now dry a huge pink tongue slurps them with thick white strings of equine saliva.
Reaching your hands to touch and make the mind believe this horror you now have a new and more terrible fact. Hands which smeared the juicy juices about the face have themselves changed. Each hand now presents a forehoof of the Mule you might yet become. Wrists are fetocks now as the hoofs attached roll and wobble making the moves of real equine type hoofs.
Billy now tries his best to shove Salmanella away but she knows just what this nanny wants! A quick snap and the big nanny bites off the buckle holding up your jeans. As the jeans fall down piled at you ankles the nanny stuffs her muzzel into your crotch. A warm licking tongue wraps about your groin which Billy, the nanny, and you know will make this too change to Mule.
