A daughter named Riho has her small mouth and tight pussy expanded by her stepfather's huge cock several times a month. When her mother is away, she tries to avoid her stepfather as much as possible, but he demands her voluptuous body and threatens to divorce her mother if she refuses. When her stepfather uses his thick fingers to stir up her mouth and pulls out her tongue, her saliva drips and she is slurped up viciously. Furthermore, when his fingers stir up the depths of her vagina and he gives her a deep throat, her uterus throbs against her reason and she unconsciously touches her own vagina. A daughter who tries to hide her female instincts in front of her stepfather, and a stepfather who wants to impregnate her with his seed. On this day, a routine creampie sex session took place.
