You feel the swelling in your behind again along with a pressing need to bend over. Clenching as hard as you can you hold it back. "You need to snap out of it." You say to the boy. You have the ears and tail of a donkey. An animal! Do you really want to be an animal?"
The boy thought for a moment. "Yes! It feels too good to be bad! Seriously man, feel your ears. Don't they feel nice?"
You again run your hands up and down the length of your own donkey ears. They feel so strong, and your hearing is better than it has ever been."
"Oh man! I feel it coming!" The boy said as he began to pant. "Huh huh hehuh heehuh heehawuh HEEEEE HAW!!!!!!!!!!!!!!!!!"
The sound made your ears twitch, and seemed to stimulate you. You really, really want to bend over.
