I know you've been a good gurl for Me these last few months. Though it was a little strange and uncomfortable at first, you've really shown Me that you are willing to work hard and prove yourself. Time to further challenge My eager little sissyboi... and what better time than during your sympathy pe ri od? Already in your lacy panties like a well behaved sissy, I assume. I've decided that you are still *too* comfortable during a time where I am UNcomfortable. So, we're going to change that... using a chastity device! Listen up, Buttercup!
