Mizuki returns for her seventh appearance in "Otona no Vinyl Book." Every day, she takes care of her father in the morning and her older brother at night, tending to their cocks. That evening, she straddled her brother, letting him play with her nipples, bringing him to the edge with handjob after handjob until precum leaked out, and grinding her pussy against his face while riding it. She then allowed intense bareback sex deep inside her vagina, receiving a creampie deep in her womb. Afterward, she happily took a second cumshot all over her cute face.
