Futakin Expansion

Futakin Expansion is a minimalist clicker game where you progressively expand a futanari character's genitalia through clicking and upgrades. The game features a "Birth" mechanic that allows you to reset progress in exchange for permanent bonuses—either increased auto-clicker speed (Assimilate) or enhanced upgrade effectiveness (Consecrate). Visually presented in 2D CG with animation, the game blends idle-game mechanics with body transformation themes. It is a spin-off in the developer's Expansion series.
