WOW. and i thought i was kinky. why don't you just choke her while you slam her or something normal. hold her upside down standing and do your thing.. you can get safer and better if she isn't dead
oh and don't tell her you love her if you don't that will jsut cause problems for you she will always want you to say it infront of your friends and blah blah big ugly mess is my guess.. if she can't give you what you need and you dont love her.... MOVE ON
