[Ahemaru] Ane o Uragiri Iinazuke Uwaki Honki Ecchi | Betraying her sister and having an affair with her fiancé

A desperate sister, Fumine, is seized by a ravenous succubus while her fiancé Kyousuke attempts a futile rescue, plunging the scene into intense bondage and explicit sexual conflict. The tension peaks as the creature's massive tentacles overwhelm her, culminating in a climactic nakadashi that underscores the betrayal and netorare themes. The album delivers a heated mix of tentacle erotica and miko's voluptuous body, making the story both provocative and gripping.
