FJIN-141 Brainwashing Mindfucker: Cumsquirt Metamorphosis with Niece Licking and Multiplication for 7 Days ~The Stinky Old Man's Multiples of Seven Make You Stupid or Feel Good~ Yura Kana

Due to her parents' trip, a lazy student and virgin cousin named Kana-chan was left at the rundown house of an unemployed NEET with 48 years of virginity for 7 days. Locked in a dim, rotting room, she had 'the seven times table' whispered in her ear endlessly every day and was forced to watch porn... At first, all she could say was 'Eww! Stop it!' 」As Kana-chan's eyes became increasingly vacant… "Everything the old man says is right..." Her brain melted away, her resistance and reason vanished, until she lifted her own skirt and moved her panties aside to expose her young slit. On the seventh night, complete collapse.
