Irritatedly.

The servant effortlessly rolls it into place and you grunt as it constricts around your cock and balls. You spend the next few minutes searching, hobbling slightly, for someplace out of sight where you can take the damned ring off. You suppose you should count yourself lucky it wasn't the kind that locked.

Regardless, it's a painful procedure and you feel somewhat less aroused than when you stepped up to the wheel. You don't know how the attendant managed to pop it on so effortlessly. You toss the ring into an expensive looking vase, feeling irreverent after your humiliation.
