[PKPD-339] Half in, half out, half girlfriend Hinano Miki Hinano (Censored)

I don't need a girlfriend, but I want to have lovey-dovey sex. I want to go on lovey-dovey dates, but I don't want to be tied down. It's hard to find a relationship that's convenient. Hinano and I are in a relationship where we care about each other and cum inside each other whenever we have free time. But we haven't asked each other to go out, and in fact he's fucking other girls too. But I like him so much that I don't want him to cheat on me, and when we meet we have raw, lovey-dovey sex. Is this a sex friend? Or a girlfriend?
