Auftauchen (2006)

Auftauchen (2006), also known as Breaking the Surface, is the brainchild of German director Felicitas Korn. It tells the story of a young woman named Nadja, a photography student who just landed a freelance gig at a popular magazine. She goes out to a club to celebrate and ends up meeting a younger man (atta girl), a skateboarder named Darius (Golo Euler). Though he's initially reluctant, the two launch into a hot and heavy affair, when things get immediately complicated. The two have tons of sex, and we see plently of bare buns from Golo Euler when he bends his woman over in the bathroom!
