Former baseball girl and leading figure in the extreme side of the costume erotic world, Rui Tsukimi, has released a new challenge work pushing the boundaries of her limits, titled 【Out? Safe? Rui Tsukimi】. As one provocative direction after another is thrown at her, is it out or safe? Even slightly out-of-bounds scenarios barely pass as safe in the heat of the moment! First, there's an endless focus on the part Rui-chan says she's most embarrassed to have seen—her anal hole. Phone masturbation? Checking the shape of her crotch? Turtle shell bondage? Facial cumshots? The P-spot? Throughout, a back-and-forth battle over "out or safe" unfolds, and each time, Rui-chan, driven to climax, is just too cute. Blushing and saying, "That's out, right?!" yet ultimately accepting everything with an overflowing spirit of service, her bound body in outrageous poses as she welcomes pleasure is irresistibly exciting. This is an evolved challenge work from Rui-chan, whose 【HENTAI Level MAX】 repeatedly surpasses the limits of costume erotica.
