My sister Ami ruled the neighborhood as the tough girl boss. I was just her little brother, and we got along well. Among her targets was a shy girl named Nagi. One summer day, while Ami and her friend Tamachan were chatting on a park bench, Nagi happened to walk by. "Found something fun," Ami smirked, clearly plotting something. She invited Nagi with a smile, "Hey, why don't you come over to my place?" Nagi looked uneasy but, too timid to refuse, followed them home. Once inside, Nagi was shoved down and pinned over. It turned out Ami and Tamachan had picked Nagi as their plaything for the day. They pinned her down, applied electric massage devices, twisted her into a tight twist, and mercilessly tickled and tormented her without mercy.
