Naturi Naughton (Notorious) has a couple of nude scenes in the pilot episode of Power, which premieres June 7 on Starz. She shows breasts for around 3 seconds as Omari Hardwick pulls her lingerie off. There are a few more glimpses of her breasts during the sex scene afterwards. There may be some bush visible briefly, but it is difficult to tell for sure with the lighting. There is one more fully nude shot as he gets off her, but only breasts are visible. In the second scene, the top half of her breasts (including nipple) are shown as she pulls her dress down while masturbating in a back seat of a car.
At around the 10-minute mark, Nathalie Emmanuel (who plays Missandei) shows breasts while kneeling in the water washing clothes. There is some jiggling involved as she is wringing out a piece of clothing. As she realizes she is being spied upon by Grey Worm, she stands fully naked for a few seconds before covering up, although only her breasts and a close-up of her butt are shown.
At the 3:38 mark in the below teaser trailer from Immaculate Conception, Oona Chaplin's left breast is briefly visible during a sex scene. The scene is very dark, but some brightening reveals that it is there. There is also a brief butt shot a few seconds, but there is no way to know that it is her. More information (and a longer trailer) can be found here. According to the uploader the trailers were put together to create interest for the script.
