After a year of marriage to Naoya—a husband perpetually consumed by work—Rika finds her sexual needs reaching an unbearable peak. Feeling neglected and emotionally drained by his absence in their bedroom life,
her desire spirals into obsession. One fateful moment catching a glimpse of her father-in-law showering ignites a powerful urge: she resolves that he must be her next lover. To initiate this forbidden encounter with the distinguished elder man of the house,
she offers herself up first by helping him bathe himself.
As Rika's mesmerizing body is touched and explored by her father-in-law’s hands during this intimate ritual washdown, the tension becomes almost unbearable. The situation escalates dramatically when Naoya stumbles home slightly intoxicated; sensing the perfect opportunity, Rika seizes the moment to seduce her father-in-law.
The two then join together for intense passion right beside her oblivious husband, planting his seed deep within her core.
