I was satisfied with my sex life with my wife, yet I couldn't help but worry about my declining stamina. Koka was a young, sensitive wife, but the truth was she wasn't fully satisfied. One day, I discovered a mysterious SD card and, out of curiosity, decided to check it. To my shock, it showed my wife Yua wildly losing control—gazing longingly at a man's thick, erect cock, sucking it meticulously, and affectionately swallowing every drop of his semen. I didn't feel anger, but instead, an intense jealousy mixed with an unprecedented arousal surged within me. In that moment, I realized my wife was a woman deeply drawn to perverted acts.
