性活週間 THE ANIMATION
Shuntarou is a high school student with an intense porn addiction, harboring inappropriate desires towards his younger sisters, which leads him to steal their underwear for his own gratification. His sisters despise him for his perverse actions, and he secretly yearns for the opposite: a kind and caring older sister. One day, after a solo session, he discovers a mysterious video game titled "Older Sister Week-Long Experience" on his computer, which he doesn't remember downloading.
Upon attempting to launch the game, he blacks out and wakes up the next morning to find his body has shrunk to that of an 11-year-old boy. When his sisters discover him, he introduces himself as Koharu, Shuntarou's internet friend. Instantly charmed by his innocent and adorable new appearance, his now-older sisters dote on him with the affectionate care he always craved.
