Nocumber 1st marks the half way part of the Chastity season. Chastember was the start, and the most celebrated month of Locktober is past, but that doesn't mean you should give up on your progress into a lifestyle modification journey that you are now on.
Nocumber is a month of pure devotion to the Dominant Woman in your life. Asking Her to remain locked is a sign of love and commitment. It means you have begin to learn the lessons of chastity and it's starting to deepen your submission and devotion to Her. This month will be where your D/s relationship with grow. She will begin to see the fruits of all Her energy She has put into making you something more than a lump of male clay.
Nocumber is a time to celebrate a deeper submission to Femdomination. Rejoice!
