The Ganguro Bitch Mating Slut That Is My Imouto

"This depraved ganguro slut, my little sister..." - this is a game rip of a game by studio Wild Flower, which was released in 2012. 

The action of the hentai takes place in the present time somewhere in Japan. The main character's little sister was always cute and fluffy, but recently something happened and her character and habits changed drastically. She became a wild ganguro slut! The hero tried to understand what happened to her, because he saw that deep down she was still his charming little sister. However, all his attempts were futile, the girl with a "tsundere" personality wouldn't let him near her, and he had no choice but to just fuck her. Which he did, by the way...
