You jump back in shock at the sight of a 6’ 4” tiger standing before you, falling into the floor. With you on the floor, the furry costume, its striped tail flickering behind it, grins and chuckles. “You’re the perfect fit. You’ll make such a good tiger, don’t’cha think?”
You stumble to your feet in a hasty, clumsy motion, and try to run away from this monstrosity, but ultimately fail, and only make it 20 ft before the tigrine costume is upon you. You feel a tendril of soft, orange/black/white fur enter into the back of your shirt as the costume begins your transformation.
The costume’s arm sleeves surround your biceps in fur as it travels down to your hands and as you can only look on in horror. The feline pelt forcefully envelopes your chest and abs in its furry, muscular form. You feel an orgasmic sensation as the dildo of the costume, which you didn’t notice earlier, slid easily into your ass, making your asshole wet. As the striped, thin tail of the costume snaked out between your shirt and shorts just above your now furry ass, you felt the huge, red, barbed, tigrine cock of the costume slowly envelop your small human penis. You feel the mask of the costume, sitting in front of your face, shoot out furry tendrils at your face, pulling itself into your face despite your resistance and then sealing the costume at the head. The final part of the costume’s invasion happens as the digitigrade legs of the costume snake out from your shorts, as the smooth, lubricated interior of the hind paws of the anthro tiger attached to your real feet, and the strong hind legs finished enveloping your legs.
You stare in shock, looking down at your new clawed hand paws, thinking you had transformed into a tiger. You spot a mirror deeper into the forbidden costumes room, understanding now the forbidden nature of the costumes, and examine your clothed furry body in the full-body mirror, surprised that you can see your human mouth through the snout of the costume, full of sharp feline teeth.
“Now that I’ve trapped you,” the costume said through the snout of the costume, but not controlling your actual mouth, “there is only one simple step to transform you forever, hehehe!”
