Unhappy, Kyoko indulges in masturbation. One night, her stepfather comes home and peeks in on Kyoko while she is bathing. The next morning, after her husband leaves for work, Kyoko has sex with her stepfather, which turns out to be pleasurable, and she gradually responds to him. A few days later, the stepfather and Kyoko give their stepson a break and the two have intense sex together. This is the work of Nagase Kyoko, a slender and beautiful MILF.
