An extreme series where we invade the "sanctuary" of a beautiful girl and drive her wild! Today's target is Shimatani Yumina, who arouses desire with her innocent smile and big ass! Yumina shyly exposes her beautiful skin and fidgets, but we tease, massage, and caress her erogenous zones, or sacred areas, until she climaxes! Yumina is so cute, playing with her own pleasurable spots and becoming unable to resist with a vibrating toy, and obediently accepting the pleasure and feeling good, so our mischievous hands escalate more and more! You'll definitely be satisfied with your climax together with this beautiful girl who is honest about her desires!
