I Touched My Stepsister

A touch-based adult minigame featuring a step-sister character. Players use various interaction points across the character's body to increase her arousal and guide her to climax, with her reactions becoming more pronounced as excitement builds. The core mechanic requires careful attention to her awakening level—in normal mode, the game ends immediately if she wakes up. Successfully completing the game unlocks a free-play mode with slightly altered character responses. Controlled entirely with keyboard and mouse: WASD for camera movement, QERT for angle adjustment, mouse wheel for zoom, left-click to trigger actions (double-click accelerates, triple-click cancels), and right-click to cancel. Clothing and sheets can be manipulated by dragging with the mouse.
