Sensitive girl Kanoko has a body so sensitive that every part of her skin is an erogenous zone. Her back, neck, and even her most intimate areas react intensely to touch, and under her older brother's hands, her body opens up even further. Her small, still-developing breasts are exquisitely sensitive—once he discovers their responsiveness, her brother relentlessly teases both pink nipples with his tongue and fingers over and over. Her hairless pussy is tight, gripping tightly around the glans the moment it enters. Despite feeling pain, Kanoko's body is shaken by her brother's thick, powerful cock thrusting violently inside her. Her delicate, highly sensitive vaginal walls gradually open up, overwhelmed by her brother's forceful thrusts.
