So, I gave in once again and used Tinder, which is of course incredibly stressful and frustrating, but you know. Needed it.

Matched with a cute girl, texted her, got number and met up (I would have bet she would flake from the apparent disinterest in the text messages, but here we are).

Long story short, I chat with her for an hour or so on a park bench, I am flirty, a little pushing and pulling a few touches here and there, we go to my place and we fuck all night, 5 rounds of really good, passionate sex.
I almost wanna share the convo right before we started making out, cause I thought it was really good (and funny), but I don't wanna get ahead of myself.

So we spend the night cuddling, kissing and fucking. I don't think she planned on getting laid that night, but she seemed pretty satisfied by the end of it.

We agree to meet up again in the future, kiss goodbye and off she goes.

Next day, I text her, that the night together was really pleasurable, she agrees. I tell her if she wants to meet up again, she can text me and left it at that.

Lo and behold, she is now texting me, wanting to meet up and asking if she "did anything wrong" (wtf is up with that)

Now, I am not really interested in getting into a relationship with this girl, I do want to have some more sex with her though, cause it was pretty good.

What steps should I take and what pit falls should I avoid to not "accidentally" get into a relationship? I am pretty unfamiliar with this territory, as almost all ONSs I had up until now have been very strictly a "one time thing" just by the very nature of them. But with this, I am unsure.
