PKPD-358 Half-in-half-out half-girlfriend Kotone Fuyuai Kotone

I don't need a girlfriend, but I want loving sex. I want a romantic date without being tied down. Finding such a convenient relationship is difficult. Koto-ne, whenever we have time, we care for each other and have unprotected sex. But we haven't said we're going out, and in reality, she's sleeping with other girls too. But I don't want her to cheat; when we meet, it's loving real-life H. What is this? A fuck buddy? A girlfriend?
