It is an acronym that refers to the practice known as “Jerk Off Instructions,” which can be translated as instructions for masturbation. This practice is usually carried out by two people—the one who masturbates and the one giving orders and instructions—and is often framed within the context of BDSM.
During this experience, the person in charge of giving instructions or the Mistress verbally controls not only the stimulation but also the orgasm of the one following the instructions. Although this practice is often associated with the online sphere, in this case, we are focusing exclusively on the in-person experience.
