You laugh at the two animals wandering about your room. They had it coming! It was only fair to get back at them. But you can't help but shake your head, feeling a little guilty for having changed your friends into farm animals. "Man, I'm such an ass!" You say, smiling, the guilt passing.
"As you wish master!" The genie says, smirking at you. Flicking you with the ashes of his cigar, he grins. "You have used your last wish to become a great ass!"
"Wha? I didn't wish for anything!" You turn to the genie in shock.
"Well, technically, you don't have to say 'I wish'. I can also interpret and anticipate my Master's wish. Actually, you'll make a fine looking donkey!"
"But...but...I don't wanna be haw donkee!" The words come out awkwardly, you realize you're beginning to change. You look around in fear. Nothing can help you. You turned your ex-girlfriend into a happy cow and your friend Adam into a pig, they probably wouldn't help you even if they understood what had happened.
You 'Hee' and 'Haw' as you gain weight, and grow larger. Unlike the other two, you're going to be a full-sized donkey! Your soon massive body easily rips open your feeble clothing. But, you're not naked for long as brown fur starts to sprout everywhere on your body. You clutch your sides as your chest barrels out. You bend over in slight discomfort when your tail snakes out from behind you. A small tuft of dark brown fur grows on the tip of your ropy tail.
The odd feeling of something pulling on your ears sends your furry hands to your head. They find your ears are steadily growing longer and flatter. They soon stand up straight at two feet long. Slowly, your face pushes outward into a muzzle, your nostrils enlarging and flaring.
A sudden rush of pleasure shoots through you. You look down and see your once human cock turning black and swelling almost like a balloon. "Haw! Haw!" You pant with each inch you gain. You watch in amazement as your new donkeyhood finishes growing. It's massive! You touch it experimentally and shudder in pleasure. You can't keep your hands off of it. You stroke it and feel it harden.
Your arms and legs begin their changes. They lock into your body, letting you only move them back and forth. You fall on the floor as your hands and feet swell and harden into hooves.
You try to rub your throbbing cock, but can't reach it anymore. The thought to pleasure yourself overrides almost everything else. A small part of you realizes you can still think like a human. You wonder, momentarily, if the other two animals are like you. Still human with an animal bodies.
Then you...
