The chaste sex slave is a common companion of many dominant women.
A heart is engraved on the chastity device. This is to show that the male slave’s owner regards him with affection.
Permanent chastity insures his success as her sex slave. Only she experiences the joy of orgasms. Without orgasms of her own her pleasure is the totality of sex for the slave.
Her beauty and her frequent teasing keeps him aroused. He channels frustration into service of his Owner.
The more perfect his performance as lover the longer he will be allowed to serve and worship her. Thus, her kind chastity extends the happiest status a male slave can know.
