Goddess Lena does not like anyone inconveniencing her and she was disappointed that this guy did it. She knew that she had to punish him for it and she did not waste any time in doing it. That is why she chose to use her chastity femdom to punish and torture him. The mistress even had huge dildos which she scared him that she would use on him if he pissed her off again.
Goddess Lena felt that her boyfriend was too idle that all he thought about was sex. She did not want him to continue being a sex addict and want to fuck her all the time. She had to make him stop and find other useful ways to pass time. So she used a chastity device to make him lessen the number of times that she had sex and it worked.
