The demon sister unleashes electric massage torture on me! The older sister has always been obsessed with electric massage, but everything changes when my childhood friend Nagae suddenly appears. Nagae used to be a playmate for both me and my sister, and it seems that twisted relationship never really ended. As Nagae passes by the park where my sister and Tamachan are talking, my sister calls her over. Frightened, Nagae is dragged back to our house, where my sister and Tamachan subject her to brutal electric massage punishment. Now, I become their next target. I try to fight back, but Tamachan and Nagae pin me down, and my sister's electric massage knocks me unconscious. Just as expected, I'm mercilessly assaulted with electric shocks by all three of them, pushed repeatedly to the brink of death!
