Russian chick lost her wet pussy at cards to her neighbor

My red-haired stepsister Diana Ryder is just adorable with one small exception - she often gets bored and therefore asks me for entertainment. To fuck her right away, neither my hand, nor even my penis, rises, and therefore I propose to play cards for a point. Sensing a catch, she refuses and I go the other way, starting to play the fool and ending up on my sisters point during sex.
