After days of playing with her stepsister's nipples, who is a hot but extremely introverted girl, she becomes hypersensitive and prone to premature orgasms! A perverted woman displaying lewd expressions during her orgasms. Saito Amiri ROYD-136

My incredibly shy stepsister has been having her nipples played with for days, resulting in her becoming hypersensitive and prone to premature ejaculation, constantly experiencing orgasms! She even said, "Hmm? Why am I...feeling so lewdly excited?" She's become a perverted girl! Influenced by those around her, my stepsister, who was too weak to stand up for herself, completely obeys me! She even lets herself drool freely, and in the end, she even actively caters to me—what an extremely lewd girl!!
