What is joi in porn?

Joi, short for "jerk off instruction," is a popular genre in porn where the performer provides verbal cues and encouragement to the viewer on how to masturbate. This can include instructions on how fast to stroke, what body parts to focus on, and what fantasies to think about. Joi videos often feature close-up shots of the performer's body and can be tailored to various preferences, such as domination, humiliation, or roleplay scenarios. The genre is popular among those who enjoy interactive and immersive experiences in their porn viewing.
