WAAA-579 Rima Arai, who made her girlfriend's younger sister (plain, shy, and not interested in sex) fall into a deep drowning state of ecstasy and turned her into a creampie urinal.

I met Rima, a landmine-type younger sister, at my girlfriend's house. She's a shut-in and shy. She 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! I trick her into having sex with me using contraceptives, begging for a blowjob after using an aphrodisiac-laced drink, choking me for orgasmic slutty fucking, and cuckolding her with all the aphrodisiac-filled slutty sex next to my sister (girlfriend). I'm going to have an ultra-masochistic creampie sex slave who'll orgasm with pleasure no matter what I do to her!
