Thoroughly nipple-trained the big-titted Kansai brat sister of the girl who always mocks me, turning her into a sensitive, quick-to-cum girl who orgasms through nipple stimulation and creampie-filled masturbator. Rima Arai
My first encounter with my girlfriend's younger sister was with a bratty girl who looked down on me despite being a complete stranger. Though she had a cute face, she was arrogant and treated me like nothing. Her indifferent attitude, even with her nipples peeking out from her no-bra outfit, stirred something inside me. Growing more and more turned on and resentful of her nipples, I couldn't bring myself to touch them at first. Though she resisted initially when I suddenly started playing with her nipples, after relentless twisting and teasing, she could no longer endure and reached orgasm. Still, she refused to drop her defiant attitude, so I intensified the nipple torture until she was gasping for breath, eventually thrusting my cock inside her and creampie-fucking her. Through this experience, the bratty, nipple-sensitive, early-ejaculating little sister gradually matures and reforms through creampie sex.
