You push your way in between two men. Looking back you see the girl has removed her clothes revealing a body covered in brown fur. A tail. That's what was in her pants. You think as you see the furry rope pulled free. How could you have been so stupid! You don't pull a girl's tail!
Lowering your head you drink out of the trough, hoping to drown your sorrows. You feel your rear straining against your pants, a soft bulge pressing into them.
You look down at the guys next to you...to see full donkey heads drinking. You ask one and get a bray in the face before he goes back to drinking. It's clear you won't get a straight answer out of them. Your ears twitch in annoyance as a mild pleasure starts to build in the seat of your pants.
You reach back and press the swollen area....and it presses back. A ragged "HEEEE-hawwww" Burst from your lips as mind shattering pleasure shoots through you. You can feel your pants stretching both in front and back.
*Riiiiiiiiiip!!!!* Looking back you see a gray furred tail shoot into the air, your pants fall away, revealing a gray, furred rear that is way too big for a human. Your knees are held slightly off the ground now, and your feet...they are numb. You can't feel them, only your shoes sloshing around your ankles. You kick them off, revealing dull black hooves at the end of furry legs.
The rush of change was difficult to deal with. You wanted to run, to get out of here, away from the growing her of asses.
"Hello all you drunk asses! How are you doing tonight!?" The Dj yells.
A cacophony of brays and happy shouts ring back.
He points at you. "It seems we have someone that is not having fun down there! An you have such a nice ass' ass! Come up here, I'll help you out!"
The encouraging shouts and brays override your worry. You awkwardly run on your hands and knees up to the stage.
The man inspects you. "What's your name?" He asks
You think hard.
"That's ok you don't need one do you?" He says
You nod stupidly, intelligence beginning to fade. The man starts massaging your legs. You feel your muscles stretching oddly In your legs. You look back with a longer neck to see the hindquarters of a donkey. You are about to protest when mind numbing pleasure hits you. Your penis is growing. You feel it extending beneath you, the head flattening. Finally it stops, and pulls up into your blackened skin. From the waist down, you are clearly a jackass, and your head feels heavy.
