I do these kind of sessions on cam cooing at them like they're a baby and telling them how I would change their dirty nappy or rock them to sleep, however I'm normally laughing so hard off screen I wouldn't be able to do those kind of booking in person even for a ton of cash. But then I can't do any domination without laughing because it's so far from my natural personality.
But the guys into the fetish will pay verrrrrry well if they like your technique because it's so hard for them to find a competent woman to indulge their fetish. Probably best to keep it virtual though.
