[Request] Looking for a comic

I can't remember the artist or character names, but it opens with a female feline (I think, can't remember,) at home. Her sister enters and tells first girl that her bf is coming by in a minute, but she has to step out for a bit. She gets in girl 1's face and says "Don't touch him! I think he might be the one, don't you dare!" or something like that. Girl 1 is like "chill, it's fine." Bf shows up. Girl 1 meets him at the door and she's dressed in something way skimpier than she was earlier. She lets him in. They sit on the couch, he tries to play it cool, but she almost immediately propositions him for sex. He's into it. They go at it all over the place. She claws his back which kinda feels like foreshadowing, because it's visible later. They hear the sister coming and panic but manage to reset before she arrives to pick up her bf.

I can't remember much else. I think it was black and white. I think the bf was a cat too. I remember claws. I think girl 1 wore glasses or maybe braces, I can't remember. I think I read it on e621. Thanks in advance.
