WAAA-121 I thoroughly drowned her shy, introverted sister who has no interest in sex in brutal sex, making her climax and finish her off as a flesh toilet with internal ejaculation Eina Sakatsuki

The cold and distant younger sister, Eina-chan, whom I met at her house. A shut-in who is shy around others. This girl, who has no interest in sex, will be forced into a world of brutal sex and turned into a flesh toy! Her untouched body will instantly transform into an obscene sex monster with non-stop orgasms! Trick her with contraceptives for brutal in-out sex, make her drink aphrodisiac drinks for awakened lustful sex, squirt with toys, and beside her sister (her), lose all reason and be taken away for intense intercourse. No matter what is done to her, she will joyfully reach orgasm—a completed ultra-masochistic in-out flesh toy!
