【The most intense erection and arousal in history】 'Sui', a shy younger sister I met at her house. She speaks little, is introverted, and shows a dismissive attitude. I'm trying to corrupt this girl, who has absolutely no interest in sex, by addicting her to aphrodisiacs and turning her into a sex toy! Her slender body transforms into a vulgar sex monster, violently erecting and arching her back repeatedly! Additional aphrodisiacs, coercive deep penetration, penis requests, eyes rolling back during intercourse, delivery driver penis craving, messy deep penetration, NTR sex with the sister (girlfriend) in front of her! Intense play also transforms into pleasure, heightening perversion, completing the super M deep penetration meat grinder!










So, the setup is you go to your girlfriend's place and find out she has a younger sister... and of course, a guy's brain immediately goes to 'She's cute, but her sister has bigger boobs...' haha. But Tsuki no E Sui as the younger sister? She didn't really give off 'dangan' vibes at all. Actually, she was kinda sexy. Maybe it's the girlfriend's request to awaken her sister? She gets intensely finger-stimulated by the aphrodisiac and starts cumming easily, even with big-dick piston action. Sui-chan was just... her moans were way more erotic than her movements, honestly.
