I watched a work featuring the mother-in-law, Ichika, who comes to the city to support her pregnant daughter-in-law. The protagonist, forbidden from masturbation after pushing his pregnant wife too far, can't resist the beautiful Ichika, who looks like a sister to his wife, and secretly films her nude during a bath. Ichika's erotic dialogue during kissing and handjobs exudes an irresistible charm, with the beautiful silhouette of her nude body in the bath being particularly memorable. Her unexpectedly active engagement in sex and the erotically beautiful expressions during masturbation form the core of the work. Towards the end, she becomes even more proactive, with her beautiful, erotic nude body highlighted under bright lighting, complemented by her nicely shaped breasts and a slender yet plump, beautiful buttocks, enhancing her supremely erotic and beautiful face. The ending feels somewhat chaotic, but it offers ample entertainment as an AV. However, some parts feel monotonous, and incorporating elements like pubic hair grooming or SM themes could allow for harder-edged performances. For instance, hardcore SM styles such as single whips, candle wax on the genitals, pulling and twisting nipples, expanding the genitals with clips and ropes, or using drill vibrators and fisting might be more suitable. Overall, the performance of the seductive mother-in-law role shines, and the escalation from an everyday setting was enjoyable.
