Two innocent anime sisters, bound by blood and virtue, find themselves in a twisted eroge game. Their pure forms are violated by monstrous phalluses, the pixelated art unable to hide the sinful acts. They struggle, they cry, but their bodies betray them, lubricating for the digital debauchery. The game's final stage sees them impaled on a massive, throbbing cock, their innocence shattered as they beg for more.
