SONE-664 Even after 30 years of marriage, my wife Odaka Saki starts to get horny over my dad's relentless dick that fucks mom every night like a monkey.

Due to her husband's transfer, Saki ended up living with her in-laws. No matter how old she got, Saki was happy to see her in-laws getting along well. However, she soon faced a shocking situation. Her father-in-law, despite his age, had a terrifyingly strong sex drive and would vigorously have sex with her mother-in-law every night. The lewd moans and obscene sounds that echoed through the nights made Saki's crotch tingle, leading her to spy on her in-laws' affairs and masturbate. I want to be hugged like an animal too... So she decided to go seek her father-in-law herself. 'I want my father-in-law's super hard dick.' The aroused daughter-in-law couldn't hold back any longer and initiated a reverse night crawl. Her bland sex life with her husband left her unsatisfied, and Saki indulged in intense sex with her father-in-law.
