My friend's mom caught me masturbating and offered to help

A friend's mother caught him masturbating and offered to help - filmed at home, looks like a living room, sofa, TV in the background. The guy clearly didn’t expect it, the camera twitches at the beginning, then he puts the phone on the shelf and films statically. She is an adult woman, about forty years old, in a dressing gown - she sits down next to him and takes him into her mouth without further ado. A long blowjob, then he gets on top and starts moving in a cowgirl position. The sound is alive - the creaking of the sofa, her voice. The quality is amateurish, the frame sometimes goes off to the side. He cums on her chest, she looks at the camera and smiles.
