Bit by bit, the ironclad obstacle that is your body is giving away under your push. Your body feels lighter, as of the weights of your changes are getting lifted away. When you physically lifts onto two legs, your eyes opens in shock at the sight of your donkey features melting away for human ones. You're turning back, somehow, under the command of your will.
You hold your breath and keep your mental push up, not daring to let go in case the donkey curse snap back in place. You watch your skin retaking the donkey hide bit by bit, your ears and tail shrinking away inch by inch. You wait until you're 100 percent human, finally letting go after seeing your pleasure pole deflating back down to normal size. And just like a dream, you're a human again - No hooves, no tail, no ears. You poke your ears and butt to confirm that you aren't hallucinating, you have indeed changed back.
"Ha! Take that!"
You whoop in joy, savoring the sound of your human voice, free of any asinine influence. You swear to yourself that you're never going to another place like this again. 'It's all free on Pleasure Island' your ass, you almost ended up as one too! Nothing's ever free - You'd like to think you've learnt your lesson here.
All that is left for you to deal with, is the matter of the evidence you've bought along with you and the Island itself...
