PKYS-014 Half-in-half-out half-girlfriend Ran-ka Ran-ka

I don't need love, but I want sex! I want to be affectionate but don't want to be tied down! The only ones who can provide such a convenient relationship are gal girls. Ranka and I will meet up and have intercourse whenever we have time. We're affectionate but she's not my girlfriend; we both have other fuck buddies, but there are times when we get jealous. What kind of relationship is this? If it exists, it's more than just a fuck buddy, less than a lover
