Once she locks your cock, there is no going back. When she unlocks it is her decision and hers alone. two days, two weeks, two months, or never, it doesn’t matter. She has taken control and your only duty is to accept and adapt. The key that she proudly displays around her neck serves multiple purposes.
First, it shows others that she is in control and has made the bold decision to strengthen your relationship by taking away your ability to orgasm or even get hard. It will serve as a launching point for conversation with other women who she will encourage to do the same.
Second, it is a constant reminder to you that she is now in charge of your marriage and that the cock that defined your virility and manhood is no more. It has been reduced to a little limp appendage that is constantly craving her. Each time she looks in the mirror and sees it in the reflection, she will be reminded that you are no longer her equal. Her sense of pride and power will grow each time, while yours will diminish. It will reinforce to her that she made the right decision. What this does to you cannot be undone. It cannot be forgotten or erased. You will eventually come to accept this as normal and soon enough forget the past when you had the ability to masturbate and make yourself cum whenever you want. You will realize you took that freedom for granted.
