Oppai Kunoichi Mikage No Junan -rj01278666- Link

Mikage is a skilled but voluptuous female ninja (kunoichi) who finds herself captured, defeated, or otherwise at the mercy of an enemy — likely a rival ninja, a corrupt lord, or a demonic entity. The story revolves around her "ordeal" (受難, junan ), meaning a trial or suffering she must endure. Unlike a typical action narrative, the focus is on sensory and psychological submission, using her physical assets (oppai) as a central element of the scenario.
