SPRD-1349 — This World Is Only For Men And Women. A Licking-Loving Old Man And His Frustrated Wife, Yuri Tadokoro

Yuri is married to her husband and lives with her father-in-law. Although sex with her husband is bland, Nao is satisfied, but as months and years pass, the number of days and times they have sex decreases. Nao's sexual desire is so strong that her husband's physical strength is at its limit, and he gives up. Yuri has no choice but to masturbate when she is alone to satisfy herself. Her father-in-law observes Nao and her married life and keeps a diary to enjoy. At one point, Nao's clothes changed. Her clothes became more revealing, and she was wearing clothes that could be mistaken for no bra or no underwear. At first, she thought it was part of her sex with her son, but when she looked back at the diary, she noticed that she had been dressing like that since the sex with her son had decreased and stopped. One day, her husband went to work and her father-in-law went out on an errand, and while she was enjoying her time masturbating alone, her father-in-law, who had been stood up, returned. Yuri's father-in-law stares in shock as she masturbates, but is turned on by her painful moans and takes her under his control. Her father-in-law's experienced caresses are intense, and he makes her cum again and again, especially with his persistent cunnilingus. Her father-in-law's penis is bigger, harder and more curved than her husband's, and the moment he penetrates her, she climaxes. A few days later, when her family has gone out, Yuri is left alone and wanders over to pick up her father-in-law's underwear from the laundry basket and gently sniffs it. Remembering her act with her father-in-law, she runs her fingers down to her crotch, and finds that Yuri's underwear is obscenely damp...
