In one scene, a fully clothed married couple is kissing passionately on the couch. Occasionally, the man touches the woman's fully clothed breasts. However no nudity is shown. (Edit: this may be in an extended version. Was not in the 1 hour 42 minute version I saw.)
We see Charles's POV as he stares at Lucinda's shapely, stocking covered legs on the commuter train.
Lucinda shows a little cleavage in several scenes.
While flirting and intoxicated, Charles bets Lucinda he can kiss her without touching her. He purposefully loses, however, so that he can kiss her. We then see them outside where Charles grabs Lucinda and passionately kisses her up against a wall.
Deanne shows a little cleavage.
We see Charles in a bubble bath, but don't see anything explicit.
Winston comments that in high school there was "all the p*ssy you could imagine."
Lucinda tells Charles that "just because we didn't f*ck" doesn't mean we didn't cross the line (of impropriety)".
We briefly see a couple passionately make out.
Referring to Lucinda, Laroche comments to Charles about "When you just wanted to f*ck her." Laroche tells Charles that he's "going to f*ck with your life" and then asks if his daughter is still a virgin.
A couple make out on a bed. The man unbuttons the woman's blouse and gropes one of her breasts, which bulges in her lacy bra. No nipple seen. The woman removes the man's top, and the camera follows the woman as she moves down his chest to his crotch, where she undoes his belt.
We see a shot of Deanne in the shower in the background of the scene. We see her bare back and the very top of her butt-crack through the frosted glass shower door, but the view below that is blocked.
