"When I snap my fingers, you will think you are a chicken!"
The hypnotism fetish is one I'm not familiar with, so the first thing that came to mind was the typical "You are now a chicken!" trope, followed by "Ok, how do I sexualise that?"
And what came to mind was ping-pong shows and egg-laying.
So here we have a hermaphrodite 'laying' golden Ben Wa eggs. Enjoy!
