At first glance, "Kokoro," who looks like a strong woman, is approached by a suspicious man while drinking alone at a bar, and he buys her a drink, but as soon as she drinks it, she loses consciousness and is taken away. When she wakes up, she is tied up behind her back in a room she has never seen before. And then she is surrounded by suspicious men. They are members of the "Female Fall Torture Research Institute." They don't care about the means, they just play with the target's body, use all means to perform pleasure torture, and plunge her into a world of pleasure she has never experienced before. In a sense, they are a despicable group. "Kokoro" actually became their test subject and was tortured. Although she resists with words, her body reacts sensitively due to the effect of the aphrodisiac, and her clitoris becomes hard in an instant! Even with anal sex, she cums like crazy many times!! The words she was resisting with a strong tone eventually change into screams begging for forgiveness, and screams of pleasure and climax…
