My step-sister 'Rima,' who suddenly appeared due to my father's remarriage, is an SS-class beauty with both a stunning face and figure! She acts sweet and serious in front of our mother, but she's actually an insane bitch. Of course, I'm not exempt from her clutches, and even my father isn't safe. What's more, she's a pervert who, despite our mother being nearby, forces intense cunnilingus on me without getting caught, making herself orgasm repeatedly until she's satisfied!
