Personal Gym NTR - A shocking cheating video of a wife who is addicted to the strength of a trainer

This year marks three years since I married my wife Haruka. Haruka has been going to the gym for three months now, worrying about her body shape. We went there together at first, but I retired after a week, and only my wife continued to attend. The gym is run by a private company and is alone with a muscular male trainer for training. There's no way I can't help but feel anxious about the distance between my wife and my trainer as she gradually gets closer... And as I became more suspicious of my wife's exposure increasing day by day, I put a recorder in my wife's bag.
