My wife and I have been steadily progressing in this kink and finally put together some ‘official’ guidelines. Curious what you all think or if you have any other interesting ideas.

Turns out I also have a hotwife kink when locked, so this incorporates that for us as well.

Chastity Agreement. 1. Upon request of key holder, cage will be applied at first reasonable opportunity.
2. Except for emergencies, cage will not be removed unless directed by key holder. Removal for emergencies does not count against the 24-hours referenced below.
3. When cage has been worn for 24-hours consecutively, key holder may engage with sexual relations with others. Other sexual partners are not allowed if he is uncaged or has been caged for less than 24 hours.
4. New sexual partners are to be agreed upon by both parties. Once a partner is agreed upon, additional visits with the same partner(s) are allowed.
5. After all sexual encounters with others, he will have the opportunity (and responsibility) to bring keyholder to orgasm orally.
6. After keyholder has sex with another, a 48-hour unlock timer starts. At the end of the 48 hours, cage is to be removed until at least one sexual act is completed. This timer restarts if keyholder has sex with another partner.
7. Anal sex is not permitted unless agreed upon in advance.
8. ‘Dates’ with other partners where sex is not the primary activity (romantic dinners, etc) are not permitted unless agreed upon in advance.
9. Keyholder may, at keyholders sole discretion, allow him an orgasm through use of vibration while caged.
10. While caged, he may engage in anal play with the goal of reaching orgasm. Penile stimulation is not allowed without consent.
11. This agreement is for the mutual fun and enjoyment of both parties. If at any point it doesn’t feel “fun” for either party, things should be paused or the agreement re-negotiated.
