Phoebe Tonkin has her first ever nude scene on next Sunday’s The Affair. As teased in the preview for this episode, Phoebe lowers her dress straps and shows her breasts around 42 minutes in. The scene is very brief but you get a pretty good view of Phoebe’s boobs. Around 10 minutes later, Phoebe is topless again during a sex scene. However, you don’t really get another good look at Phoebe’s breasts since the scene is dark and her breasts are usually at the bottom of the frame or partially blocked.
Phoebe is actually in the 2nd part of the episode. In part 1, Emily Browning is topless during a sex scene around 26 minutes in.
