SSNI-346 The image of her fucking another man from morning till night during the two days I was away makes me sick to my stomach

"Tsukasa" seemed to have no desires, always appearing unsatisfied in a mysterious way. I was drawn to her like that and started dating, thinking I was spending happy days... One day, I left the house we were living together in and decided on a whim to set up a hidden camera. What appeared on it... A male teacher from her middle school days, a few years older, brought back home, having sex from morning till night. She wore an expression of pure pleasure, enjoying every moment.
