A stunningly beautiful older sister, known for her extremely sadistic personality that even drove away her boyfriends. Her daily routine involves relentlessly teasing her younger brother's testicles every morning—not just for fun, but as part of a cruel ritual: checking his morning wood, then skillfully edging him without allowing release, keeping him on the brink all day. By evening, the built-up semen is violently unleashed through intense creampie sex, finally satisfying his pent-up desire. When her brother, unable to endure the torment, peeks at her in the bath, she punishes him with an even harsher titty fuck, pushing him to his absolute limit. This extreme scenario is depicted in full POV, letting you fully experience the sister's obsessive, dominating presence.
