Twisting your neck, you look round for the guy that is with you and see that he too is almost completely changed. Only his face, flushed and sweaty, remains human, but it looks seriously out of place at the end of a hairy donkey body. Just as your surely must!
Peering back, the lad flexes his butt muscles, splitting his white cargo shorts completely. A sharp flick of his tail sends them flying into a corner. He flashes you a toothy grin. He really loves that tail!
And then, simultaneously, both his face and yours begin to writhe and pulse, bones and flesh stretching forward, crackling horribly. Your noses start to broaden; your lips and tongues thicken; manes sprout from the backs of your necks. A long slaver of drool drips down your bristly chin.
"ERRRRGGGH!" Your teeth have begun to hurt. You can taste blood oozing out of your gums. Grimacing, you bare your teeth, licking them with your lengthening tongue. They're loose, and blood is seeping from their roots. As you toss your head in discomfort four fall to the floor at your feet! Then the rest fall out too. Wincing and spluttering you feel new teeth pushing out in their place - big, blocky teeth - which rapidly crowd your much-enlarged jaws.
"EEEEEAAARRGH!" you bray hoarsely as your new donkey muzzle finally stops growing. "EEEEEAAARRGH!"
Whipping your long tail, you feel what's left of your pants fall from your butt. Your physical transformation is now complete; only your mind remains human. But oddly, the thought that preoccupies you as you and your companion trot out of the building isn't what happens next, or going in search of a burger to turn you back (yeah, you remembered that!), or wondering if you'll ever bump into this weird young guy again, when HE's found himself some junk food. No... your one overriding thought is simply this: 'Hell, at least I don't have to shave for a while!'
