Sex Trainer's Diary: Hidden Kink

A stealth-based adult simulation game where you play as a professional sexual trainer hired to pursue Mio, a woman who works at a convenience store. The game blends covert stalking mechanics with sexual content—you must follow Mio through residential areas, trains, and parks without being spotted, using environmental hiding spots and items to avoid detection. Once captured, intimate 3D scenes unlock. Between encounters, you can interact with Mio at her workplace, purchase items, and play minigames to earn money. The game features an affection system where sexual performance ratings unlock additional scenes and artwork. Multiple explorable maps and fully voice-acted sequences create a simulation-focused experience centered on fulfilling the protagonist's submissive desires.
