WAAA-621 Karin Kitaoka, who made her girlfriend's younger sister (plain, shy, and not interested in sex) fall into a state of drowning in drug-induced sex and turned her into a creampie urinal.

At her house, I met her younger sister, Karin, who is a shut-in and shy. This girl has no interest in sex, so I'm going to get her addicted to drugs and turn her into a sex slave! Her undeveloped, slender body quickly transforms into a vulgar sex monster with instant orgasms! She's tricked into having sex with him under the pretense of birth control, begging for a blowjob after being given an aphrodisiac-laced drink, choking him for orgasmic slutty fucking, and cuckolding him with all the aphrodisiac-filled slutty sex right next to her older sister (girlfriend). She's an ultra-masochistic sex slave who'll orgasm with pleasure no matter what you do to her!
