Spoiled little sister "Koko." Although it's a consequence of my indulgence, her recent behavior has become too much to bear. Unable to tolerate it any longer, I've decided to try a method I've been curious about for a while— A bad friend lent me a book on "hypnosis." Skeptical about whether such a thing really works, I decided to give it a try—? This is a short visual novel about a brother's struggle to bring back his honest and adorable little sister from the past. Enjoy Koko's embarrassing yet cute moments, including wetting, enemas, diapers, etc. ■ Basic CG: 15 images (total 164 including variations) *Please note that there are many depictions of waste.
