A perverted man spots an ordinary office lady walking down the street, kidnaps her in a deserted spot, covers her mouth with a handkerchief soaked in an aphrodisiac, puts her to sleep, and takes her to a hotel. After playing with the woman's body as she lies unconscious on the bed, the man rubs an even more powerful aphrodisiac into her pussy and begins to turn her into a sex slave. The woman continues to cum from the pleasure of the aphrodisiac and big dick sex that is given to her over and over again, and before she knows it, she is reborn as a slutty sex slave who desires the man's dick herself.
