Czech Soles - Card game challenge with Katty

Katty want to play cards so why not join her. What are we playing for? Ok, I have an idea: who wins can ask the other for anythig and he/she has to do it. What do you say? You agree hoping to win and at least make out with Katty but boy are you wrong. She already knows what she will make you to do...and it's not what you wanted...
