Post-sex scene, both characters are lying topless together but they strategically keep the woman's breasts covered with their arms. Later in the episode, a couple is having sex in the background, the woman is seen topless from the side, breasts visible for a few seconds. A lot of sexual dialog throughout the episode and throughout the entire series.
One scene very visibly shows two people having sex in the bed next to one of the main characters.
