My estranged adult son returned home in financial trouble and asked to move back in, bringing along his new wife, Ryo. I reluctantly let them stay but hated everything she did, constantly mocking and criticizing her whenever she handled the housework. Once Ryo reached her limit, she summoned me to a dark room. Waiting there was not merely my daughter-in-law, but the most terrifying and skilled dominatrix at the SM club I had visited for years—the mistress who knew me by my humiliating slave name, “Bald Baby Toru,” and was ready to put me back under her control.
