Sliced by my claws

You are the subject of a new experiment of Euryale. She locks you up in a tiny chastity cage full of metal spikes, before injecting you an unclear solution will a long syringe... Everything gets foggy after that... You think you are seeing her hand turning into a giant metal claw, while she is telling you that even with a cage, your testicles are perfectly exposed to her... The next step suddenly wakes you up, as she starts slicing your testicles with her claws. The pain is unbearable, but not as much as the pain you will feel when Euryale decides to practice her skills with a scalpel, slowly dissecting the pathetic sack of your masculinity...
