Why?

Now, why would a no-longer-masochistic sub (i swear i'm not, He swears i am. It's a matter of contention), buy her Master implements of torment to torture her with? i keep asking myself this question. i am sure come tomorrow night, after He gets a chance to experiment with His new toys, i will just settle on the obvious answer--i'm completely nuts and secretly hate myself. For now though (since He doesn't actually have them in His possession), i can say "because He wanted them."
