Rico Marlon. Allen King. I believe it's from Sharing Allen King's Hole. Here's another shot of them kissing:

This is what a good day at the office looks like ....
No idea who that is smiling, but the butt belongs to Kostja Ullmann, and its a scene from a 2015 German film called 3 Türken und ein Baby.
