Second, whenever you have the money, I want you to set aside a small allowance. It shouldn't be too big, just enough to cut into your leisure funds. You will pick something you don't need, and go without it, every month.
This money goes into purchasing toys for yourself. I want you to always be thinking about the next thing you're going to subject yourself to, whether it's a painful set of spikes for your cage or a frilly pair of panties, a gag and collar for wearing around the house or a plug for wearing around the office. I want you to use each and every thing you buy at least once. I want you to always feel like your life is getting kinkier and kinkier as the items pile up. You can save half of it each month if you want a really big item - I want you to anticipate that.
