Woah there!
You spy a very realistic looking horse's head, sitting atop the crumpled pile that must be the rest of the horse costume. Lifting it up, you can see it is a full sized mare costume, with a seam along the spine opening up so you could fit inside. Oddly, though, instead of having hooves on the front it has human hands.
You quickly slip your feet inside the hind legs of the costume, the skin of the costume gripping your feet tightly as they reach the bottom. With the costume now resting loosely around your waist, you suddenly feel a half-sucking, half-ballooning sensation as your legs contract lower down, and expanded upwards to fill the costume. Soon, you can feel the strength of your new muscles, as well as the cool air against what was now your own skin and hooves.
The costume seemed to be urging you in, pulling itself up and around you. Your butt expands, getting much heavier as it fills the horse's behind, followed by several 'pops' as your spine stretches outwards - soon, a tail is swishing away behind you.. Gradually, the rest of your torso follows suit, the costume wrapping around your torso, hugging it tightly, expanding some parts and contracting others. Suddenly, there is a strange flattening and churning sensation between your legs. Looking down, with some horror, you could see you were most definitely female now.
You soon find yourself putting your hands into the arms of the costume, the material hugging them tightly as your arms are given a very slender form, your hands tipped with very hard, thick, black nails. The torso of the costume finishes wrapping itself around you, giving your body a decidedly feminine (and sexy) look - one made all the more potent by the two rising breasts on your chest, forming neat mounds held firm by your new skin<span class="female">your breasts held firm by your new skin</span>.
All that is left now is the head of the costume, which you press onto your face, suddenly plunging you into near darkness - light still coming in from the eye and mouth holes ahead of you. With a sucking sensation, you feel your face begin to stretch out into the head, your jaw becoming longer and longer - as are your teeth. You neck braces itself a little, lengthening too, and bulging with a few extra muscles to support the added weight. Soon, you feel your face meet the resistance of the costume's skin, all your features aligning, new ears twitching as you finally look out of your new eyes (your vision now, irritatingly, obscured by your elongated face). You looked down now at your body: sexy, female, and equine. Foreign as it was, you quite liked it. But whatever are you going to do with yourself now?
