She was taking a nap. Suddenly, her smartphone was placed next to her. I had never looked at her smartphone in the three years since we started dating. I just had a premonition and looked at her smartphone for the first time. The image folder was filled with graduation photos, photos from when we went on dates, and a photo folder filled with many memories... What is this? Photos and videos I don't remember. What's going on? She's sucking a stranger's dick. When was this video taken? It was taken quite recently. The neat and gentle girl I knew was not in the smartphone video. There was a completely different personality of a lewd woman who was greedily moaning as per her instincts. Why? On another day, I looked at her smartphone at the moment she was sleeping. The video had been updated. Moreover, she looked like she was being treated roughly in an M play and was feeling insanely good. It was frustrating... but I got an erection watching her being cuckolded, and before I knew it, I was stroking her. I was so excited by the sight of her being cuckolded that my brain juice and penis juice couldn't stop. I was awakened to my perverted sexual tendencies. However, she noticed, and when I tried to check my phone as usual next to her while she was pretending to be asleep, I found it. Is this the end of my three years with her? No, it's just the beginning. She says that she likes me, but she can't forget the dick of the man she cheated on me with. I just want to love me. If that's the case, then show me how you're being cuckolded by me. That's when my strange relationship with her began, and I hid myself and watched her go crazy as she was cuckolded on a live call, and it made me depressed. This feels so good!
