A few years ago, we had great chemistry, and my wife was very passionate. But lately, she doesn't seem to feel much during sex. I used to travel frequently for work, and whenever I came home, she would be very bold and aggressive—her attitude completely captivated me. Recently, though, things have changed, and I started sensing something was off. Could it be... that my wife is cheating on me? The suspicion gnawed at me until I could no longer stay calm. Driven by impulse, I decided to hide a camera and secretly monitor her.
