You take off all your clothes so you don't get them wet or mess them up if you manage to transform. You dip one foot into the cold water, and shiver. You step in. You walk out a little ways. You feel ridiculous. You hope no one is going to think you look stupid staring into the water naked! At first, you try to picture the biggest and most well-endowed horse you can think of. And then, you think, if you're gonna go big, why not go huge? You could turn into an elephant--and get an elephant-sized boner!
That's if this stupid were-creature spell actually works. You're pretty sure you've read this same spell in a dozen chain emails and probably seen it on other TV shows. You fail to see how it's less superstitious than letting a were-horse bite you. Why should you believe some random drunk guy you met at a party in a town that you only moved to so you can could attend some third-rate college a few miles away? Oh well, you might as well give it a try. You focus intently on your reflection and try to imagine yourself as a large elephant. Nothing happens, so you swear under your breath and kick the water with your barefoot. Nash is probably hiding in the bushes right now, filming you on his smart phone for social media. You probably just imagined him turning into a horse!
You step out of the water, shake your feet dry, and pick up your underwear to put it back on. But you drop the garment in shock when you see that your whole body, and the water of the nearby pond, are starting to glow! The mental image of an elephant, and the inward sound of a loud trumpet, flood into your brain with such overwhelming force that you stumble back and land in a seated position on the grass. You're left panting for breath, no longer glowing, wondering what you just experienced.
An irresistible horniness fills you, and it doesn't take long for you penis to become erect. You grab it and start stroking, but it gets harder to stimulate yourself as your dick becomes longer and thicker. By the time you takes two hands to hold it, you realize this is definitely no longer a normal erection, so you reluctantly take your hands off to look at it. The skin of your dick has turned gray, and it's still growing. Eventually you realize it's almost as long as an arm! And then it starts to twitch.
* Wait, did my penis just move? On its own? *
Yes, it did. Focusing on your penis more closely and thinking back to how that felt, you manage to make it happen again. Soon your penis is slithering around under its own power while you experiment with all the different ways you can move it. Your experiments are interrupted when your left testicle gets sucked back out of your shrinking scrotum and into your body! Then your right one follows it!
"My balls!" you shout. You reach down and can no longer your ball sack any more, much less the balls that you have guarded carefully inside it your whole life. Where did they go? Did you gain a penis this large just to get magically castrated anyway? But you realize you're still horny. Your testicles are still tingling with desire, only they're tingling from inside your abdomen now. Somewhat nervously after that experience, you reach out and touch your snaking gray cock, stretching out both hands to sort of wrangle with it like some kind of eel.
"Oh, oh!" you moan and soon feel giant surges of liquid pulsing through your enormous member. You feel a twitch in your ears that causes them to lean forward and then back against your head. You want to touch them and figure out what's going on up there, but your still wrestling your penile behemoth. Once your orgasm is over you sneak over to the water to see your reflection. Wow. Your ears are bigger! And they're moving. You can flap them around as easily as you can raise your arms (or slither your cock!). You feel your lips getting pushed apart by something hard at the same time you see your top canine teeth poking out above your lips like fangs. As those teeth grow down, thicken up and curve forward, you grin widely with the realization that they look increasingly like tusks!
