Shit, it's just too much to ignore. You use both hands to grip the thick, black foreskin that covers your draft horse cock and start to slide it up and down. The sensations make you gasp and shiver, and the pre gets thicker. Curious, you lick the sticky fluid from the flat glans, finding it to be almost like salty mucus. However, your mouth starts to tingle, lips twitching. Startled, you pull back. You reach up and feel your lips - they have gotten much thicker, and the lower part of your face seems to be pushed out some. Huh? Looking back at your cock puts the head in contact with your mouth before you realize it, and your muscular, flexible equine lips slide around it as more pre gets pumped out.
"Mmmphh... no!" You twist your head away from the spurting horse cock and stumble to look in the mirror. The face looking back at you isn't familiar, unless you think of Budweiser commercials. You are developing the muzzle of a Clydesdale horse,a nd as you watch your eyes get bigger and start to change into liquid brown animal orbs.
How is this possible? The horse cock bobs in front of your chest, and you can feel the huge testicles pulsing beneath it. If a little pre did this, what would happen if you swallowed a load of the real stuff? Even as you think that, you find yourself lipping the huge flare. And why not? You can't stay like this! You are a huge freak, your body starting to swell and get muscular, but also become more bestial. A mature Clydesdale stallion - somehow you know that's what you'll be soon if you don;t stop... and you feel the pressure suddenly build as your horse balls suddenly release the flood of horse semen that will make you a real animal!
