There was one years ago, a shonen, that was uncomfortable and not this open in sex, it was just for sm. When it is sm with a contract and not just "let's be violent", they tend to have spoken rules and stop words.
I know that all of the sm don't have to be painful, but it was good to understand the "good part" of this SM world. Then you can find those who prefer no rules and just have hardcore sex
When you think they touched the basics, they come with something you already forgot. And all the good SM things done with the right amount of pain.
Let's go daddy.
