She enjoys her work and currently doesn't want children. Her husband is a freelance photographer. Neither of them is restrictive, but she is dissatisfied with her husband's lack of sexual interest. Before marriage, she was addicted to sex with a married partner, but they broke up after he became serious. She wants to relive the excitement of his erotic self-portraits, craves being seen, and can't resist seeking thrills and pleasure. This is why she applied to participate in the program.
