Before this post I never knew that "Throne" was a kink website I could visit. And now you tell me not to search out your account on it. Cruel!

Far be it from me to suggest improvements to perfection. But a slow cycle fucking machine set to penetrate at random intervals might add a sense of jeopardy (happy to lend you ours). Oh and maybe a Kee Klamp device around the waist to keep it in position.
