Tall and lovely mature beauty Kasumi Shirakawa makes her debut in cervical stimulation! To begin, a dildo is inserted to locate her deep-lying cervix. She quickly feels pleasure from within and reaches orgasm. Penetrated even deeper, she moans and twists her body in ecstasy. Addicted to the sensation, she continues thrusting and cums again. When a man's fingers reach her cervix and stimulate her with manual penetration, she involuntarily urinates while convulsing. As her fingers pinch the "uterine opening" deep within the cervix, her breathing turns ragged, her body writhes uncontrollably, and she thrashes in overwhelming agony. On all fours, with fingers driven deep inside, she arches her hips upward, trembling violently—now completely lost in sensation. Even before a large cock is inserted, she gasps in anticipation, her body craving penetration. The moment it enters, her lower abdomen is slowly pressed, and despite a nervous expression from the unfamiliar sensation, she cums almost instantly. In the crawling position, overwhelmed by this first-time pleasure, her body screams in ecstasy, collapsing forward onto her elbows as she climaxes. Shaken repeatedly in her womb, she sobs and orgasms uncontrollably, hyperventilating and surrendering completely. Terrified by the approaching pleasure, she is entirely dominated from cervix to body. This release includes an exclusive making-of video, capturing behind-the-scenes moments from the shoot. In the making-of, Kasumi uses massage oil, filling the room with a pleasant fragrance. When signing a polaroid, the tall Kasumi sits slightly hunched in a chair, giving off an unexpectedly cute impression. The making-of is packed with special content for fans and is definitely worth watching.
