JUR-378 My mother-in-law will teach you an adult kiss… A voluptuous stepmother who takes the innocent lips and first experience of her husband’s young son Mariko Koto

Mariko decided to marry a man who had a son, Yusuke, who was refusing to go to school. Yusuke, her husband’s child from a previous marriage, could not accept Mariko as his mother and kept his distance even while they lived together. Wanting to grow closer to Yusuke, Mariko gently told him that she wanted to support him as family and as a mother, and Yusuke gradually began to open up. However, his school refusal did not change, and when Mariko listened to him, she learned that he had struggled because of a relationship with a woman. In response to Yusuke’s request to understand a woman’s body, Mariko softly guided him, saying, Mom will start by teaching you about an adult kiss.
