Description: Meet the Suruga sisters, Ryoko, Maki and Miho. Ever since their parents died they've been living together, getting by as best they can. The Suruga sisters have a secret they can't tell anyone - due to an unexplained phenomenon, whenever one of the girls becomes sexually excited, the other two will instantly feel the same emotions, no matter where they are. As they go about their daily lives, each girl never knows when she'll become sexually aroused by the emotions of the other sisters! A unique "zapping adventure" for adults in which you play the game through the eyes of the three Suruga sisters, this is an interactive hentai adventure like no other: at any time during the game you can "zap" into one of the other characters, playing the game from their point of view.
