My wife "Rinne" and I were supposed to be a couple that everyone envied. One day, I finished work early and returned home with a feeling of having gained something, and there were unfamiliar men's shoes at the entrance. While feeling a bad premonition, I peeked into the living room, and there was my wife with a bewitching expression I had never seen before, devouring the neighbor's man's cock... I wanted to look away, but my feet were as if glued to the floor, and anger, shock at being betrayed, and an inexplicable turmoil swirled in the depths of my chest. Furthermore, in my wife's smartphone, there was a video of Rinne obeying the neighbor's commands and offering her body. Realizing that I couldn't take my eyes off my wife's figure reflected on the screen, in a mixture of self-loathing and arousal, I lied that "Today I'll be late due to overtime" and decided to investigate.
