I met Nanaka-chan, a landmine-type younger sister at her girlfriend’s house. She’s shy, talkative, and has a cold attitude. I’m going to drug this girl, who has no interest in sex, and turn her into a sex toy! In no time, the unsociable gloomy girl has transformed into a vulgar sex monster who orgasms repeatedly! I’m going to drug her and have sex with her, begging for a dick, get the delivery man involved in a threesome, and have sex with her while I’m drugging her and cuckolding her next to my sister (girlfriend)! She’s a super-masochistic creampie urinal who enjoys anything erotic and accepts even hardcore perversion with a smile!
