The day she arrived home with her child, the doorbell rang. Opening the front door, I saw her standing there holding a trunk case. She smiled and said, "I got here a bit early," then introduced the child: "This is my daughter from my previous marriage, Chinami." Behind her stood little Chinami, fidgeting nervously. She urged her, "Come on, they're letting us stay here, so say hello properly." Trembling, Chinami stammered, "P-p-please take care of me from today." That night, I had sex with her—right next to her stepdaughter. The next day, the child curiously asked, "Hey, what were you and Mom doing last night?" She replied, "I saw everything." Chinami whispered, "I've never seen Mom make that face before... I want to try it too." Her mother responded, "Is it okay...?" giving permission. Chinami said, "Last night, this part got really big," and asked, "How do you make it grow like that?" Her mother answered, "Last night, Mom was licking it, right? I want to do it too." The girl began licking her mother's cock. "I want to do it just like Mom did..." she murmured. As her mother touched her wet pussy, she said, "It tingles, like I need to pee." Chinami panted, "Haa, haa, haa... move just like Mom did, more, please," and her mother whispered, "Mom's selfish... it feels this good, huh?" Gazing into each other's eyes, they engaged in intense, adult sex. In missionary and cowgirl positions, focusing on deep connection and sensation, their relationship deepened.
