The car has started moving again and the girl is down on her knees braying at you, still crying for you to help her.
Suddenly her hips pop, flinging her down onto her hands and causing her dress to split by the seams. You look at the naked half donkey on all fours before you and notice you are starting to become aroused.
You can see her large breasts hanging down between her arms and wobbling with every movement. You reach down into your underwear to start playing with yourself at this sight.
The girl has noticed you playing with herself and has turned to present her behind to you. She lifts her tail allowing you to see her still human pussy. She makes a sound between a bray and a moan and you see her labia starting to grow. Her lips were darkening and her sparse pubic hair was starting to grow thick and turn into fur.
You pull down your underwear revealing your genitalia and she pushes her ass up towards you.
