Recently, Ichika joined the family as my new stepsister. At first, she seemed like any ordinary, delicate girl, but gradually her true nature began to emerge. She started relieving stress by toying with her older brother's penis, going far beyond mere oral sex—using her tight, gripping pussy to torment his bare cock, repeatedly bringing him to the edge only to deny him release, delighting in his suffering. Though she appears sweet and gentle at first glance, in reality, she harbors a cruel, sadistic side.
