[Keep-Out] I Got My Hands on an Actual Hypnosis App, so I Used It to Turn My Onee-San Into My Toy

A pair of boys discover a forbidden hypnosis app on a cracked phone and decide to test its power on their busty older neighbor, Koharu, who goes from a normal, energetic girl-next-door with a short bob and sailor uniform to a glassy-eyed, docile toy. Their twisted seduction escalates from innocent groping on the bed to complete domination, with the dazed girl eagerly offering her mouth and her tight body to whoever commands her. The final page reveals a maid outfit and a broken chastity device, hinting that Koharu's life as their "personal cum dump" has only just begun.
