Goddess Lena needed to pass a message and she did it using her chastity humiliation fetish. She made her man wear it and once he realized how it gave her power over his sexuality, he was shocked and he was alarmed. But he also realized that he had to stop doing certain things which drove her to seek such drastic measures to control him. The message was home and the plan worked.
Goddess Lena did not like how her ex had tried to soil her good name. She knew he loved to have sex all the time and so she tricked him and got him to her house where she got him to wear a chastity device. She locked it and hid the keys then she chased him from her house. He could not use his dick for anything other than peeing and it was real torture for him.
Goddess Lena felt that this guy had to wear the chastity device she had bought for him but first of all, he had to be humiliated so that he learned to do as she said without questioning her. So the mistress made him lick her bare feet and after that, he did not ask her anything when she told him to wear the chastity device. He just wore it and went about his business.
