A very nice update! It's nice for Karina to be able to claim her desired reward if she wins. There's some grammar errors in the scene, but that aside, a very enjoyable update.
Any hints as to what might be next?
While I'm not any kind of professional, I could try and give it a look over to correct some things? From what I recall, the weirdest parts of the dialogue for Karina's victory, is just her saying she presses the female MC to her bosom - when she's clearly pushing her down into her womanly bit!
And oooh, interesting indeed!
