Shrugging you don't see any harm in trying something on so you reach in looking for something interesting to try. Just then your face contorts into a confused look as your hand grasps something soft. Pulling out the item your eyes go wide as you look at what you grabbed, it seemed to be a extremely phallic looking object made of silicon that you had no trouble identifying as a butt plug. What was interesting about it though was that attached to the phallic object was a fake tail that had a riser that you could fit between your but cheeks to have the tail in the correct position as any other tail.
Confused but also curious you ponder the situation for a moment. Thinking back you realize you always did want to try anal and you realized now could be your chance. Making sure none of the other guys notice you shove the tail back into the bag and carry it out with you as you search the house for a empty room where you can get a little privacy. Finally finding such a room you sneak in before anyone else can see you and lock the door behind you. The pink mist seeps into the room from the crack under the door with a large grin on it's ghostly face.
You then get undressed and open the bag pulling out the tail with the biggest grin you ever had. You then frown as you realize you don't have any lube but just then you notice the plug take on a shiny sheen and a questioning touch reveals that the plug is already covered in lube ready to be inserted as if by magic. Shrugging you then start pushing the plug in. It was difficult at first but you then take a deep breath as you force the plug into your ass and once it's in it fits perfectly in your entrance. You moan and begin gyrating your hips in an effort to get off.
Just then the ghost smiles as pink mist engulfs the tail. Just then you stop in your tracks as a loud and audible moan escapes your mouth as you realize the plug is vibrating. At the same time this is happening the tail attached to the plug is also wagging and you chop it up to the plug being some sort of kink toy that appeals to a certain group. You don't consider yourself to be a furry but hey a plug's a plug right? As you bask in your orgasm you fail to notice the vibration of the butt plug causing your ass and hips to balloon out as you shrink in height at the same time shrinking from your normal 5' 10" height to a much shorter 5' height.
As you lay there thoroughly enjoying the experience you fail to notice your waist shrink inward and your shoulders lose their broadness. Your arms and legs also shrink down with your hands and feet also shrinking down to small and petite hands and feet. Your feet shrink from a size 12 all the way down to a size 6. You then moan again as a pair of DD size breasts grow out on your chest. You then could swear you feel a tingling sensation on your face as your lips plump up and your nose shrinks as your jawline becomes much smaller and rounder. Your eyes become much more alluring and sultry and as you lay there in the afterglow feeling satisfied you were about to remove the butt plug when suddenly it started vibrating even faster and the tail began to wag even faster.
Just then you moan even louder only this time it's far more girly and you gasp as you realize something is off. Looking down your heart sinks as you realize what is going on far too late. You then attempt to remove the tail but then your heart stops as you realize that the object holding the tail on is gone and the tail has attached itself to your lower spine. You start moaning again but your moan then turns into a howl as you realize your fate is sealed. Your head then grows tingly with pain as your ears move to the top of your head and furry fox ears form on your head. Your hair then grows down your head turning a bright red color roughly the same shade of red as the tail and your new ears.
Finally you whimper as your manhood finally shrinks into your body forming a new clit that gives way to a fully functioning vagina. Your balls also disappear into your body taking place as your ovaries. The rest of your body loses it's body hair making your skin completely smooth and to finish off your transformation your nails all grow out into claws. Your eyes then flash an otherworldly shade of pink as your memories fade away and new ones flood your head making you lick your lips in anticipation. Just then you hear a loud knock on the door and hear the voice of someone on the other side of the door, who could it be? You giggle with anticipation as you stalk the door as if you were stalking your prey.
