NSFW: Kinky sex ideas?

Me and my girlfriend are very open to exploring new fetishes and types of kinky sex. It’s the first time in both of our lives that we’ve found someone else just as freaky as ourselves, so we are eager to try any and everything (except including other people).

We already tie each other up and blindfold each other on a regular basis. We’ve played with ice and penetration with different objects. We tease each other to the edge of orgasm then stop multiple times almost every time we make love.

So, we are looking for new and exciting ideas. Anyone have any suggestions?

Also, my favorite kinky thing is sex slave roleplay, but since I never got to experience it with anyone before, I am lost on ideas of how to play it right. Other than being dominated and talked down to during sex, how else can we incorporate the slave/master roleplay into our sex life?
