My little sister 'Konatsu' has a bad personality and is insolent, pissing me off. She always looks down on me as if I'm beneath her just because I'm her brother. Her good looks and huge F-cup tits also piss me off. Over the past year, her body has been developing rapidly... I've been wanting to fuck her for so long... One day, 'Konatsu' was caught in a sudden downpour and returned home soaked to the bone... I reached my limit of enduring stress and pent-up frustration, and before I knew it, I had restrained and raped her... #ちんP
