Jerk Off Instruction, often shortened to JOI, is a form of erotic direction in which one person verbally guides another through masturbation, controlling the pace, technique, and timing of the session.
JOI is popular because it lets a partner or performer hold control over an intimate act even from a distance, and it works especially well in audio, video, and live cam formats where the voice itself does the work. Many people enjoy the mix of submission, teasing, and the forced focus on sensation that comes from following someone else's commands rather than their own instincts.
Worth knowing: Because JOI involves power exchange and often edging or denial, agreeing on a safeword or check-in phrase beforehand and discussing aftercare for the drop that can follow intense sessions matters.
Also called: JOI, jack off instruction, guided masturbation, masturbation instruction, edging instruction, countdown JOI, denial play
