PKPD-335 Half inside half outside half girlfriend Machi Ikinono Machi

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. They have sex inside whenever they have free time. But they're not saying they want to go out, and in reality, they're also sleeping with other girls. But I don't want them to cheat, and when we meet, it's loving raw sex. Is this a friends-with-benefits situation? A girlfriend?
