The term "jerk-off-voyeur" consists of three individual terms: jerk-off, voyeur.
1) "Jerk-off" is a slang term used to describe the act of self-pleasuring, often in the context of masturbation. This can be performed by both men and women.
2) "Voyeur" refers to someone who derives pleasure or sexual gratification from observing others, typically in intimate or private situations. This person is called a voyeur because they are secretly watching or spying on others for their own sexual satisfaction.
When combined, the tag "jerk-off-voyeur" would suggest a video where one person is masturbating while secretly observing (or being observed) by another individual who is also enjoying the act of self-pleasuring. This kind of scenario often involves elements of exhibitionism and spying, with both parties deriving pleasure from their shared experience.
