The Second Husband — Carmenica Diaz

Rika Ishikawa and her assistant Pamela Staines are hired by wealthy women to either punish or train the wayward or non-performing husbands of their clients.
Rika and Pamela convince Claire's husband Gary, he has been in an accident and is now in hospital. Much humiliation and teasing follows in order to “persuade” Gary to properly serve on his frustrated wife.
Using hypnosis, trigger phrases are embedded in Gary's subconscious to control his sexual performance. Gary soon learns his place and how to serve Claire.
Claire decides that isn't enough and increases her control until she is very happy with her second husband.
