A little over an hour into Luce, Naomi Watts steps into the shower and we see her topless briefly. The very next scene, Naomi shows her breasts during a very dark and brief sex scene.
A few minutes later, Marsha Stephanie Blake strips off all her clothes in the school lobby and prances around during an episode. Marsha shows everything but might be wearing a merkin. We then see part of this scene again from another angle as it is shown on a laptop.
Finally, at around 97 minutes, Andrea Bang shows her right breast during a sex scene. It’s not very clear if Andrea shows nipple or not however as the scene is shown from someone else’s point of view.
