Futanari Reverse! Futanari Succubus and Office Lady

An ichaicha (intimate romance) puzzle-solving RPG set in a fantasy world. Lala, a blonde office worker with bob-cut hair and glasses, is summoned to another world where she meets Lulu, a carefree futanari succubus with an open sexual appetite. The two quickly become close and team up to explore the fantasy world together, solving puzzles and uncovering secrets. Gameplay involves conversation commands where Lulu offers advice and hints, magic spells that transform Lala (such as into a cat to access new areas), and exploration. The game features multiple H-scenes across two playthroughs, with different content and variations between the first and second runs, rewarding replay.
