Chastity Contracts

There are examples all over the place. I think it's an excellent start point, and essential, if you're going to hire the services of a professional. However, I think they lack a certain spontaneity.

I think the best approach is to start slow. Talk over what turns you both on. Then when some rules have been established, then go for the full-on roll play. I think if you rush those first steps of discovery, you are going to miss out on oportunities for some fun times.
