Mag was fully occupied with her exercise bicycle when her hubby Jim came in. the sight of his cycling wife got him horny. He loved the position and the look from behind so he decided to get the advantage from her favorite position. He had to do it quick so he wouldn't interrupt her physical exercises for long. He just showed her a few more exercises with his own device and she loved these pushing and pulling and cock jumping. It seemed her training machine was doomed to gather just dust from now on.
