Five years into marriage, the 25-year-old voluptuous big-titted wife maintains her prime feminine body. Due to diabetes, her husband increasingly suffers from dizziness and can no longer perform sexually. Overcome with guilt, he decides to ask an acquaintance to sleep with his wife. For the sake of her beloved husband, she agrees to repay a fictional debt with her body. Initially reluctant and feeling no pleasure, she gradually rediscovers feminine ecstasy as her long-neglected body is stimulated—eventually climaxing with another man's cock. Afterward, she becomes addicted to carnal pleasure, indulging in masturbation and even inviting the man herself for repeated creampie-filled encounters.
