I would say that this is a classic, a guy who has been working the night shifts for a while now. Has got the feeling that his wife is complaining a bit to much a bout her headache. He sets up a hidden cam in the living-room and bedroom and voila the result is some great hardcore amateur action.
The full movie can be found here, where he even bangs her doggy-style in the living-room.

His college friends just knew this was about to happen. So the bought a small remote cam and glued it next to the light on the ceiling. Luckily for us you can also hear her. And she is a real screamer when he starts pounding her real deep. You really can see him how he is trying to get real deep inside! Enjoy the full gallery here!
