Your only a few feet away from the now completely formed jenny, when you stop clopping forward and realized in the recesses of his changing mind what is happening.
The young man that was forced into the room earlier is now a female jackass in heat... Your clouded mind pauses on that last thought as you take in more deep breaths.
Your donkey cock is throbbing, and the jenny is clearly dismayed by your hesitation. She clops back a few steps until her rump pushes up against the end of your face. You start licking at her, and decide that as soon as your done with her you'll get back to trying to escape. You rear up and after a few tries find your mark and enter her, as soon as you begin humping the very last thoughts of escaping vanish.
One of the women captors opens a view slot in the door and chuckles as she watches what has become of the two young men.
