I've been trying to locate the title of a hentai, after coming upon a scene from it long ago. I know it's not much to go by, but the scene in particular is one where a woman (think with brown hair) is kidnapped and tied to a swing set in the middle of a playground. Then gangbanged by a group of men. The scene was very memorable due to not seeing it in a hentai before, so I've been trying to find the full episode.
