Female led relationships discussion

We came across a thread discussing a slave boy experiencing something akin to a menstrual cycle. Mistress Julie and her coach, Mistress Sherri, are no strangers to this phenomenon. My pet Toni and I share the same experience, but with a twist that bites hard. The Mistress keeps a coffee can filled with tags numbered 1 through 31. She kicks off the game by drawing one tag from it. If the date on that drawn tag coincides with a day my “cycle” deems completely safe for intercourse, I get tied up and remain so until that specific date arrives, at which point I am released and permitted to climax. The catch? Toni has to perform the deed without using her hands. By the way, when Toni pulls a lucky “safe” tag, it becomes my turn again. However, if the drawn date falls on an unsafe day for sex or corresponds to a non-existent date in our calendar (like the 31st appearing during a month with only thirty days) according to my “cycle,” then another tag is pulled from the can for the following month. My luck hasn’t been great lately; I might win every block in a football pool except one and still lose all four quarters. Unfortunately, it seems Toni has good fortune riding shotgun.
