Hazuki Wakamiya controls the viewer's ejaculation through detailed instructions on genital touching, masturbation speed, techniques, timing, and whether or not they can cum—all directed at her cohabiting partner. This is a fully subjective, immersive experience where Hazuki issues explicit verbal commands, and the viewer obeys, creating a virtual world of complete ejaculation control. Alone together, you follow her orders step by step, progressing through challenges and ultimately being led to ultimate pleasure.
