A brother-sister sex scene where the brother defeats the tyrannical sister! A live-action adaptation of a rapidly rising work! "You know, you're really annoying me," "Don't talk back to me," the sister who seems soft-spoken at work, takes out all her explosive stress on her brother when she gets home. However, the brother has 'identified' an erotic selfie account on a certain social networking site. "This is...my sister, right?" The erotic account that should never be found out has been found out by someone who should never know it. The revenge of the oppressed brother begins. A collaboration with a popular doujin work!
