This wasn't how I expected tonight going

Supergirl-yeah, you heard right Supergirl, not Kara-and Lena have been having this little arrangement going for some weeks. An arrangement in which they had make out, if you know what I mean. But Lena have always wanted Kara to be there with her instead of Supergirl and sometimes had fantasies about that. It all goes wrong when she accidentally says the wrong name. Or does it? There's a revelation and some feelings are uncovered, which leads the couple to really have a romantic relationship.

It's mostly fluff, if you don't want to read smut just skip the first part. I'm telling you, most of the story is fluff anyways.
