Firm Porn Videos
"Firm" in the context of a porn video tag generally refers to the physical attribute of being hard or taut. This can be applied to different body parts, such as nipples, penises, and buttocks. In most cases, it implies that these body parts are erect or well-defined. For example, "firm nipples" would indicate that the nipples are erect or standing out due to being stimulated. Similarly, "firm ass" would imply that the buttocks are well-toned and taut, often visually enhancing their appearance in a sexual context.
