I recently saw a photo of a bottom whose top set out mouse traps on his naked thighs during a scene. I really like the drama and suspense of the sub not knowing if, when, or how the mouse traps will set off. It got me thinking about role-playing scenes that incorporate intense psychological drama (such as interrogation scenes).

What are some very psychological and dramatic scenes one can play out (scenes more skewed toward violent such as interrogation scenes)? Even if it's not necessarily a completely drawn out role-play scene, what are some ways to really instill suspenseful fear into the person that's bottoming?

"Mind-fcking" is another term that comes to mind in this context...
