One good thing when you're doing it with a masochist is that you dont need her permission to try stuff
NEWS FLASH: CONSENT IS ABOUT AS IN AS IT GETS! ALWAYS MAKE SURE YOU GET YOUR PARTNER'S PERMISSION BEFORE TRYING ANYTHING NEW!!!
You're going to do double penetration!?Well, no...Um... this was supposed to be a joke...That's fine now hurry up and give it to me, my master-!D-Don't be ridiculous!Huh?
Your ass!?There's no way that will fit!
If you think I'm lying go ahead and try it!There's no way it's going to fit in my ass!That's way too big to possibly fit!
