Inkling is a term used in the context of BDSM and kinky fetishes. It generally refers to someone who has an interest or curiosity about BDSM or kink but may not have explored it extensively, or someone who is unsure of their role or preferences within these activities. The term "inkling" implies that the person may be in the process of discovering their interests and preferences, similar to the idea of having a hunch or intuition about something. In a porn video context, this tag could indicate that the content involves individuals who are exploring BDSM or kinky activities for the first time or those who are uncertain of their role within these activities.
