SONE-800 A perfect match between a girlfriend who wants to cheat and a boyfriend who wants to be cuckolded! Rei Kuroshima, driven into a gloomy self-pleasure NTR situation after being shown off to another man

She was taking a nap, and her smartphone happened to be lying beside her. We had been dating for three years, and I had never once looked through her phone. But for some reason, I felt uneasy and ended up checking it for the first time.

In the photo folder were pictures from graduation, photos from our dates, and a folder full of memories… Wait, what is this? There were photos and videos I had no memory of. What does this mean? She was with an unknown man in the videos. When was this filmed? It looked like it had been recorded fairly recently.

The modest, kind girlfriend I knew was nowhere in those videos. Instead, there was a completely different side of her, acting on raw impulse and desire. Why was this happening?

On another day, while she was asleep, I checked her phone again. The videos had been updated. And there she was, looking overwhelmed and intensely aroused in a rough, dominant scene. I felt frustrated… but before I knew it, I was aroused by the sight of her being taken by someone else, and I started pleasuring myself.

That was when I awakened to a twisted fetish. But she noticed. When I tried to check her phone as usual beside her while she pretended to be asleep, I was caught.

Was our three-year relationship over? No, that wasn’t it. This was where it was beginning.

According to her, she still liked me, but she couldn’t forget the other man. She wanted to keep loving me, too. If that’s the case, then show me that side of you… the side where you’re with someone else.

From there, our strange relationship began. I secretly watched her being overwhelmed and losing herself through live calls, and it drove me into a dark, obsessive state… That was what felt best of all.

This is a story about a couple whose desires perfectly matched: a girlfriend who wanted to cheat, and a boyfriend whose hidden desire for being left behind awakened.
