PKYS-014 Half inside, half outside, half girlfriend Ranka

I don’t need love, but I do want sex! I want to cuddle, but I don’t want to be tied down! When I’m looking for that kind of convenient relationship, all I can find is a gal. Whenever I have free time, I meet up with Ranka and we cuddle and cum inside each other. We cuddle, but we’re not girlfriends; we both have other sex friends, but we get jealous sometimes. What exactly is this relationship? If it were to exist, it would be more than sex friends, and we’d cum inside each other, but it’s less than lovers.
