Af with Karina was an unexpected experience. She invited me in with little to no preparation and because of that it was slower, sensual and more serious.
Even if she is grimacing she will keep trying so long as you respect her when she tells you to pause or slow down. Because of this, if you are expecting fun, quick, smiley gfe af it may be better to book a different girl. However, this experience with Karina tickled my brain in a different way and I'd return to see her again if I'm in a certain mood.
Her head game is phenomenonal as well. 10 out of 10 there.
