That was my former situation with my wife and her boyfriend except I either received a video or was allowed in an adjacent room to listen. I was never allowed to get that close unless he let me video the action myself.
She looks like a great fuck, those legs wrapped around that guy is hot. The guy that’s getting to fuck her, WTF is up with wearing a baseball hat while fucking a delicious blonde? And the dude off camera stroking his limp cock the entire time. She can do better than this setup.
