I've been suspended from rafters, trees, tide over saw horses, stools, beds, bent over car doors, bent over knees, tired of a tables, beaten with about anything you can imagine, fucked by all size cocks and dildos. Even fucked buy dogs. All by orders of my master....
As I have told my subbies: "You may sigh, moan, groan, sob or weep, mutter, invoke deities, even imprecate but if you raise your voice, I will give you real cause to scream". I leave my marks often but quiet misery is among my favorite pleasures to watch. There are rewards for silent suffering.
