MIAE-065 Himekawa Yuuna: I Turned the Daughter of My Wife into a Desperate Girl by Tightly Binding and Harsh Training… Kitorune Kawanoguchi, Schoolgirl, Mother Deep Throating

Yuuna, a high school girl unable to accept her mother's remarriage, becomes subjected to degrading sexual acts by her stepfather, who calls her 'mistress.' Her developing body, small budding breasts—all become targets for his sick desires. Day after day, she's tormented with tight bondage, forced into humiliating positions until she breaks. At first, she resists fiercely, but eventually, her helpless body starts craving his touch. She begins to beg, 'Please violate me,' willingly taking his cock into her mouth. This is the beginning of an obsessive, carnal life, climaxing in desperate, shuddering orgasms.
