The story of three art-school grads realizing that their degrees and artistic ambitions haven't necessarily prepared them for the real world and putting themselves in positions to confirm that darkness and pain are necessary to produce great art.
"Just 'cause she's your mother doesn't mean that she's not a hot MILF to someone else..."
Dan wants his mom to pose nude for him so that he can paint her, but she doesn't want to because she feels weird about it. So Dan asks his friend to photograph her naked and then he will just draw her nude portraits based on the photographs that his friend will take later. Dan's mom and his friend end up fucking on the day of the photoshoot. The seduction part while Dan's friend shoots his mom is quite sexy. We see the mom's tits and we see them kiss after sex but there's no pumping scene.
Dan's ex-girlfriend Stephanie is also cheating on her husband with him. She usually comes to his apartment to fuck him but we only see their kissing parts. At the end part of the movie, Stephanie's husband sees Dan kiss her during an art show in a gallery.
