Kanna, a serious adolescent little sister with big tits, had been keeping some distance from her older brother. Then, a gadget-otaku friend of her brother's brought over a mysterious "hypnosis app." Once installed, this app allows the user to forcibly summon the target regardless of where they are, and even freely manipulate their memories. Having obtained this ultimate cheat item, the brother begins summoning his sister at will, training her into a convenient sex toy for his own pleasure... Under the spell of hypnosis, the little sister exposes a vulgar ahegao face and repeatedly reaches climax through nipple stimulation. An onahole doll that can be called upon anytime, anywhere, with just a single app. #Cock
