Karina had her motives to ambush Karla like this, yet the main thing she wanted here was to utterly destroy the redhead for the injustice she had done to Karina, which today was going to be a fierce lesson taught where Karla would never try again, or at the very least be a little more careful whom she did it too! The girl seemed pretty stunned from it all and it was time for Karina to take advantage from that, raising up enough to give Karla a glare before she hunkered low and would grab Karla by the arm and hair, tugging her up to sit, then slowly up to her feet along with Karina.
She would then tuck Karla's head closer and against her shoulder, sliding her hands down the woman's body and to the back of her knees, taking two solid handfuls of them before she push in while lifting Karla up by them, slowly pulling her up until the back of her neck was resting on Karina's shoulder while Karina's grasp went lower just to spread those legs.
Should Karla behave to that point, Karina would straight up and walk around while holding Karla like that, just hurting that neck a little more while spreading those legs wider, aiming to taunt Karla, or at the very least grant her more time to recover and realize what was going on before she would do anything else.
