Saki Oishi was seduced by the lustrous body of her mother-in-law, who aspires to be an underwear model... A week in which she drowned in her instincts over and over again.
Since this spring, the three of us have been living together with our stepmother, Saki, because of our stepfather's affair. A few days later, her mother-in-law informed me that she had applied for a job as a model for an apparel brand and had been hired because she wanted to work again. Her wife and I were both happy, but when we heard her story in detail, it seemed like she was working as an underwear model. My serious wife is completely against it, and my mother-in-law and I can't say anything back to her strong-willed wife. Her stepmom couldn't give up, so the next morning she put on some sexy underwear and started doing obscene poses in front of me to see if she would pass...
