[Kaeru Douhu] Akane Aoi Futanari Shokushu Bote Ero Trap Dungeon (VOICEROID) [desudesu]

Akane and Aoi Kotonoha wander into an ero trap dungeon where grasping tentacles strip them bare and hold them open before they can run. What begins as a fight for survival curdles into something far more twisted when Aoi—sporting devil horns and a lashing tail—mounts her sister, purrs praise for swallowing every drop, and pumps Akane's ass until her belly balloons into a taut, dripping sphere. Relentless tentacle restraint, sister-on-sister dominance, and a stomach-deforming cumflation climax make this a dungeon crawl with no safe way out.
