JUR-781 | I was caught by my father-in-law, who had returned from a tuna fishing boat after three months of abstinence. - Ichino Aoi

Urged by her husband, Makoto, Aoi visits her father-in-law's house alone. There, her father-in-law, Ryōzō, returns home after a three-month tuna fishing trip, having been in a state of abstinence. Mistaken for a housekeeper, Aoi is unable to resist Ryōzō's insatiable desires and is forcibly embraced by him. Aoi is captivated by her father-in-law's wild strength, which her husband lacks, and by his attentiveness as he serves her freshly caught fish. Taking advantage of Makoto's absence, she sinks into a sea of ​​depravity, and three months later, she returns without hesitation to her father-in-law, where her desires await her once again.
