The family I married into ran a chiropractic clinic. One day, when he sees a customer ogling Erika, her father-in-law's dormant lust awakens. His father-in-law intends to teach Erika the procedure, but he can't stand her voluptuous body, so he crosses the line and joins forces with a regular customer to rape Erika. . The daughter-in-law feels that she is being raped and quits, so she is now waiting to be raped by her father-in-law even at her home where her husband is.
