Plapgasm, or simply "plap," refers to an orgasm achieved by rhythmically striking the testicles with a dildo while locked in a chastity cage. This technique is most common in sissy, chastity, and humiliation-based fetish communities.
For sissies, plapgasm turns orgasm into something that comes from endurance, submission, and sacrifice. People may enjoy that it is something that must be earned through suffering, effort, or devotion.
In chastity play, plapgasm is something that may happen despite restriction. In this case, it has an indirect, frustrating, or humiliating charge to it, which chastity lovers may get off on.
In general, plapgasm is achieved through rhythmic, repeated percussion of the testicles, although not everyone is able to orgasm this way.
