This scene suffers from bad lighting. Don't get me wrong, it's a great scene but it could have been much better.
You can tell Anjelica is eager to get her butt fucked. She warms up with fingering her anus and continues with the same while blowing off her boyfriend. He sees this so he says fuck it and forgets about the blowjob and moves to her rear where he gives her a rimjob then stuffs his big pole into her brown hole. Now that he is in he won't quit, he just pounds her harder and harder making her scream out loud!
