I think some people misunderstand the reason for Kurumi's jealousy, she's not just jealous because Rio is there with them (although she does seem to regret inviting her to sit down) but because Rio evidently knows a side of Ruriko that she has little to no access to. Ruriko speaks informal with her even though she still calls her own wife "Kurumi-san", she has obviously discussed romance with Rio too, which Ruriko and Kurumi haven't (for obvious reasons, as Ruriko is 100% seriously into Kurumi), etc. So I'd say its less that Kurumi believes Rio is going to snatch away her wife, but rather that she's shocked how a seeming stranger can have so much more intimate knowledge of her wife than she does
That's an interesting observation, but to play Devil's Advocate, perhaps Ruriko's use of informal language on Rio implies that she doesn't respect her the way she does Kurumi.
It may well in this particular case. But nonetheless, using someone's first name without honorifics is still usually an indication of closeness or even intimacy, so it's hardly weird for it to make Kurumi feel weird. And, the whole "finding her annoying" thing . . . let's not forget that Japanese very often treat annoyed bickering as a form, or sign, of closeness; how often have we seen a character cheesed off with another character, only for someone to say "You two sure get along well"? And how often has that in fact turned out to be a sign of things to come? Ruriko treating Rio as an annoyance is not something Kurumi can be expected to feel comforted by, even if in this particular case she doesn't actually have anything to worry about.
