Centaur legs

You rummage around for a costume you're looking for and pulled out a horse costume, they're supposed to be the horse legs, but they're definitely too fuzzy or in this case furry, because they felt way too itch to wear for more than a few minutes at best, you brought it back to your living room and closed the blinds to make sure nobody see you, it felt a bit awkward to put together since you need to glue and tape the back part to the front from the inside, but you eventually stuck them on your legs and began the same process when you fused the fake breasts and feel them as they were yours, as mass began to manifest in your backside and when you're finished, you look behind you to see your body having fused with the costume and becoming a centaur, after of course falling to your side after realizing that you still need to teach yourself how to walk with equine legs, and the slight problem of fitting through doors...

"Well, at leat I'm a bit taller now...", you commented as you flexed the strength of your lower equine body.
