DLDSS-521 From the time my husband leaves for work at 9 AM until he returns at 6 PM… I’m having ‘making a grandson’ sex with my father-in-law. Yoda Rin

Caring for her father-in-law, who lost her mother-in-law and was left alone, Rin decided to move in with her husband Akira at her parents’ house. Although her husband was caring and kind, he was also serious and methodical, and he hated having his routine disrupted more than anything. Of course, she doesn’t spend the night with her husband, and one night she feels a pain in her body, and her father-in-law spies on her as she comforts herself. The next morning, when her husband goes to work, her father-in-law reveals his hidden desires to Rin and devours Rin’s body… At first Rin refuses, but gradually her body becomes honest.
