I met Mio, a landmine-type younger sister at my girlfriend's house. She's shy and cold. I'm going to make this girl, who isn't interested in sex, addicted to drugs and turn her into a human toilet! Her undeveloped slender body quickly transforms into a vulgar sex monster with instant orgasms! I trick her into using contraception as a contraceptive and rape her with drugs, I use aphrodisiac as bait to make her beg for a dick with a blowjob, I get my classmates involved in a lewd threesome, and I give her aphrodisiac and have sex with her next to my sister (girlfriend). I'm going to happily accept anything and turn her into a super masochistic human toilet!
