What would you do if your sister was an AV actress? What would you do if she had a lewd, erotic body? This work is about a brother who ends up with such a sexy sister. Reika Otone, who loves her brother and says, "My type is my younger brother!", and her brother Kun, who has no interest in her at all. Even though she has such an erotic body, he has no interest at all! "I'll blindfold you so your face doesn't show, so why don't you try being an AV actor?" he says, blindfolded. Not realizing that his sister is giving him a blowjob, his dick is super hard! Even though he said, "I'm not interested in my sister," he even drips pre-cum!
