You jump from your bed, hoping the stuff didn't stick yet. Fat chance. As you stand, the latex coating your ass comes right along with you. Just great, now your butt is pink!
Unfortunately for you, it doesn't stop there. The latex begins to wobble, puffing out slightly. You know where this is going - you saw it with your foot - so you try to grab it so you can pull it off before it gets the chance. You squeeze the smooth latex with your fingers. Success! Now you just have to pull it, and as you do you feel the latex pulling with your hand... but not away from from your backside.
You let go immediately and look back, hoping you stopped yourself in time. Where there was once your human booty, there now defiantly stands a very rabbity one. The pink cheeks are noticeably bigger than the originals (though you might still be able to squeeze into your pants), and where you'd been pulling you can clearly see a nice round white latex bunny tail.
