Our Rivalry Continues in Bed!? My Childhood Friend's Challenge!

Sumire is a competitive childhood friend you reunite with at university. What began as a lifelong rivalry in academics, sports, and games escalates into an intimate contest when she challenges you to a sexual encounter. The game combines narrative progression across six story chapters with strategic sexual gameplay: using directional controls, you must discover Sumire's sensitive spots while managing your own stamina and momentum. Each encounter features hand-drawn animations, dynamic character reactions tied to your performance, and multiple difficulty levels. As you progress, you earn experience points to customize your character's stats, unlock new sexual positions, and face an increasingly aggressive Sumire with higher stakes and shifting attitudes.
