Rui Tsukimi, a former baseball girl leading the extreme side of the "kierotic" (clothed erotic) world, releases a new challenge work pushing the boundaries of NG limits: "Out? Safe? Rui Tsukimi"! As one scene after another is thrown her way, is it out or safe? Even slightly "out" scenes become barely "safe" depending on the flow of the moment! First, the camera infinitely focuses on the one part of her ass she says is most embarrassing to have seen! Phone masturbation? Checking the shape of her pussy? Tortoise-shell bondage? Facials? Cervix play? The entire shoot is a tug-of-war over whether it's "out or safe," and Rui-chan is just too cute as she's driven to climax every time! Despite blushing and saying "That's out!", her generous service spirit means she accepts everything in the end. You won't be able to stop your excitement watching her reach pleasure in outrageous poses while tied up! This is Rui-chan's further evolved challenge, pushing the limits of clothed erotica with "HENTAI Level MAX"!
