So what exactly did you get up to? Did you peg them? Or did you just tie them up, slap them around and ride them? Also, did any of them cum too quickly? What did you do to them if they did? I've only ever talked to two sadist women before.
I used hot wax on them, I ran a knife down one's chest and put a knife to his throat during sex, I whipped them, suffocated and strangled them.
