>>88357597Why? Are you trying to imagine Mori domming you? There's no one 'most extreme' thing you can do to a sub. I can give you an example a popular fetish I suppose. Fisting. Doesn't really hurt once you've worked your way up to easily taking a fist. Like, it can be a little sore, but if it hurts you're doing it wrong, and generally people who can take a fist have worked their way up to the point that it might feel tight but not be painful. I once saw a woman stick her hand up to the elbow in her man's asshole.
