You are browsing through many isles of the Magic Shop after your friends told you about it, they had many physical changes, some with animal instincts, others with animal speed, feet legs arms hands head noses neck chest belly tails and so on, you being a person of reality are skeptical of their claims but you have to admot that your curiosity was peaked by how they were changing, you were browsing all of them but what caught your interest the most were buttplug tails these buttplugs were made of metal, silicone, plastic, rubber, or other materials and they had fake materials that felt similar to real tails, you were curious of how anal masturbation felt but you never had the courage to try it, today that would change, all of them are cheap (as in the price not the quality) you find one you like and you bring it to the cashier. After you pay for it, you get knocked out unconscious and brought to a secret room, you are immobolized in a spread out pose and you see two mirrors one in front of you and one behind you so you can see your butthole, you have been kidnapped, the cashier appears before you and inserts the buttplug tail into your anus, your butthole eagerly accepts the intrusive material and when it is fully in your asshole dissolves the metal, silicone, plastic, rubber tip and your muscles and skin connect to the tail, not only is it flexible and prehensile, but now the thing doesn't even feel fake, it feels real like it always belonged on your body. Oh no, the Buttplug Tail is now a Real Tail and the Real Tail is now permanent and you can never remove it and you can never poop again. This means your butthole is now your tailhole. You cry tears of sadness of upon realizing you will never be a normal tailless human again but instead one with a Tail sticking out of your asshole and then faint and pass out after realizing all of this and everything that has happened to you. What tail did you buy and what animal will you become? Or will you stay a human but with a naked hairless fleshy tail coming out of your former Tailhole?
