Sph Porn Videos
SPH stands for "sounding with a penis" in the context of BDSM and kink. In a porn video, it refers to an act where one partner inserts a sound into their urethra. A sound is typically a hollow tube that can be inserted into the urethral opening at the tip of the penis for sexual pleasure or as part of BDSM practices. The term SPH is used to categorize video content that includes this specific activity.
