The term "wool" in the context of a porn video tag refers to a specific kink or fetish involving the use of wool, such as wearing woolen clothing or using it for bondage play. This could include scenarios where individuals derive pleasure from being wrapped, tied, or covered in woolen material, either for sensory stimulation or as part of roleplaying scenarios like shepherds and sheep, or even just due to the texture and feel of wool. In some cases, it might also indicate a preference for scenes set in rural or farm-related environments where wool is a prominent element, such as barns or pastures.
