Someone has a camera or phone out while the sex is happening, turning the scene into a porn shoot or a deliberate homemade recording. You usually see angles framed like a behind-the-scenes set, with characters posing, spreading, and fucking with an eye toward the lens, and sometimes a director vibe calling shots. The focus leans into exhibitionism and voyeurism, with close-ups of penetration, cumshots, and the extra thrill of being watched and documented.
