It was surprisingly easy to screen those guys. It only took one question, right after the "I won't fuck without condoms and dams, not up to negotiation"… A very simple "Are you willing to be tied up?".
And it didn't take overly complicated kinbaku, either, just a simple tie around the wrists, or a pair of handcuffs. Of course, if the mood struck, kinbaku was also an option. But mainly, once a man replied affirmatively to her little question, she knew she could start talking seriously.
They were always down for it. She could always talk them into the drill. Every bit of it. That simple reply, that "yes" made her smile, inhale and bite her lip.
The procedure was always the same; explain her style of domination, her requirements, lay down how the guy would only be an object. A toy. That always excited them. Some just wanted to experiment, so "toy" sounded harmless enough, and some were so deeply into submission, the word "toy" sounded deep enough.
