During summer vacation, I use hypnosis to turn my little sister into a lewd bitch, who hungrily mounts and rides my cock until she drains me dry.

The story follows the male protagonist who accidentally masters hypnosis during summer vacation. After using it on his cute little sister, he transforms her into a completely lewd bitch. The sister evolves from an innocent girl into a lustful sex beast, eagerly mounting and riding the protagonist's cock in wild positions to milk every drop of semen until he is utterly drained. The work features exaggerated H-scenes in a 3D adult anime style, exploring taboo brother-sister relations and hypnosis training themes.
