PKPD-339 - Half-Japanese, half-foreign, half-girlfriend Hinano Miki Hinano

I don't need a girlfriend, but I want loving sex. I want affectionate dates, but I don't want to be controlled. It's difficult to find such a convenient relationship. Hinano and I have a relationship where we care about each other and have intercourse whenever we have time. But she doesn't say let's date, and she's actually messing around with other girls too. But I like her enough that I don't want her to cheat, and when we meet, we have loving sex. Is this a friends-with-benefits situation? A girlfriend?
