SPRD-1165 In this world, there are only men and women. A father who loves licking and a frustrated wife, Nao Yuki.

Nao is married to her husband and lives with her father-in-law. - Nao was satisfied with the sex she had with her husband, although it was casual, but as each month and year passed, the number of days and times they had sex decreased. - Nao's sexual desire was so strong that her husband's physical strength reached its limit and he started making noises. - Nao had no choice but to cheat by masturbating during her alone time. - The father-in-law was enjoying their married life, observing Nao and keeping a diary. - At some point, Nao's clothes changed. - High exposure and no bra? - No panties? - He was dressed in such a way that it was easy to mistake him for it. - At first I thought it was part of her activities with her son, but when she looked back at her diary, she realized that she had been acting like that ever since her activities with her son had decreased and stopped. - One day, my husband went to work and my father-in-law went out on some errands, and when I was enjoying some solo masturbation time, my father-in-law had come back after being absent from his errands. - Her father-in-law stares at Nao, who is absorbed in masturbation, with a surprised expression, but becomes aroused by Nao's painful moans and ends up putting Nao in a handbasket. - Her father-in-law's seasoned caress is amazing, and she is made to cum over and over again by his cunnilingus, which is especially naughty. - Her father-in-law's dick was bigger and harder than her husband's, and Nao reached climax the moment he penetrated her. - A few days later, her family left and Nao, alone, wandered off to take out her father-in-law's underwear from the laundry basket and sniffed it. - Nao's underwear was obscenely damp as she ran her fingers along her crotch, remembering what she had done with her stepfather.
