My Secret Kink Is So Dark...

I've been with my partner for five years now... We're solid, stable, everything you could ask for in a relationship. But there's this one thing that I've kept from him for so long... It started as just something to think about when we couldn't agree on what to do next, but it's become more and more real for me lately... My secret kink is bondage and humiliation... I want someone to take control over me completely. Someone who won't let me go until I break down into tears and beg them to stop... The thought of being utterly powerless... It turns me on in a way that nothing else can match. But it scares the hell out of me too. What if he found out? He's never been really into anything like this... We talk openly about sex, but I know this one thing will be hard to accept... Have you ever wanted something so dark and forbidden from your partner? How did you get them on board with it...?
