Strip Baseball with Cool Older Sister

A cool, composed woman named Rena is approached on the street and invited to participate in a high-stakes photography shoot for a 100,000 yen prize. The game is strip rock-paper-scissors: she must remove clothing each time she loses, with her body photographed throughout. As she gradually loses her composure and is stripped down, the stakes escalate dramatically. The game culminates in explicit sexual content. The player's choices determine what happens next and the character's fate.
