Knuckles Porn Videos
"Knuckles" in the context of a porn video tag refers to the act of stimulating a person's genitals with the knuckles, typically during a hand job. This is done by gripping the penis or labia with the palm facing outward and using the knuckles to rub against the sensitive areas instead of the fingers. It can provide a different sensation compared to using fingers, increasing pleasure for the receiving partner.
In a non-sexual context, "knuckles" could also mean gripping or holding onto something firmly with one's hands, typically clenching the fists so that the knuckles touch the surface being held. However, in the porn video tag context, it is safe to assume that it refers to the act of sexual stimulation described above.
