According to a couple of reviews, Keri Russell showed some rear nudity on tonight's episode of The Americans. Descriptions not mine.
Tonight on The Americans, Keri Russell is naked on a bed and there is an shot of her ass from above and some side shots. Some scenes in her underwear also.
Just coming here to post about Keri. Her face and ass are visible at the same time in both the side and overhead shot. Bit more ass (mostly from the side) from Keri near the end of the episode being done doggy style.
