[Rurimaru] Takarabako no Himitsu | Secret of Treasure Box (2D Comic Magazine Mimic ni Ryoujoku sareru Heroine Vol. 1) [Kinsei Translations]

A dungeon map promises the 'Secret of Treasure Box,' but the treasure hunt becomes a trap when Miku, a self-described succubus, reveals a tentacled creature that can borrow a woman's body. What starts as playful competition between two women turns into a claustrophobic mix of body-sharing, transformation, and tentacle domination, with desire and helplessness tangled together in the chest chamber. Across the escalating panels, the dungeon's stone walls, lurking monster, and intertwined bodies turn a simple map search into a dark erotic fantasy about who is feeding on whom.
