Investigator MAMI infiltrates the manufacturing base of the aphrodisiac Heaven Searam, but in fact the infiltration itself is a trap set by the enemy! She is restrained and interrogated by the boss of the organization, TK, about obscene aphrodisiacs, and the investigator's steely will is put to the test! MAMI, who is caught in the trap, is interrogated with the aphrodisiac and raped, then hung from the ceiling and subjected to further powerful interrogation and toy torture, and then she is tied up and subjected to more aphrodisiac sex, and finally, she is tied up with rough rope and falls into a crazy 3P sex! The magic of the rope digging into her skin brings investigator MAMI to the ground!
