Characters have visible tattoos on their skin, like sleeves, chest pieces, tramp stamps, or small symbols on the hip, neck, or hands. The ink often gets framed in close-ups during sex scenes, with sweat and body heat making the lines pop while bodies grind together. It can also sell a specific vibe, like rough biker/gang energy, punk confidence, or an “owned” marking that gets shown off while someone is getting fucked.
