[CHINESE-SUBTITLE] WAAA-371 I made my girlfriend's younger sister (plain, shy, and not interested in sex) fall into a state of drug-induced ecstasy and turned her into a creampie urinal Mei Itsukaichi

I met Mei-chan, a landmine-type younger sister at my 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! The big-breasted girl who is a real treat quickly turns into a vulgar sex monster who cums repeatedly! I'm going to trick her into taking birth control pills and have sex with her, beg for a dick mixed with aphrodisiac, get the delivery man involved in a threesome, and have sex with her next to my sister (girlfriend) with all the aphrodisiac in it! I'm going to have a super-masochistic creampie meat urinal that will accept anything, even perversion!
