Marina is a very submissive slut. She wears a collar and sucks a cock. We learn that she was won in a poker game. She sucks him off with great enthusiasm till he cums in her mouth. She is delighted with the treat and says "thank you step-daddy" and then plays with the cum till she drinks the last of it. She begs for water as she sucks the last of his cum off her fingers. She is slapped in the face twice and is grateful for that as well. Whew!
