Athena has always been very protective of her stepbrother Austin. The guy is constantly bullied by David, a total douchebag from his school, but he doesn't do anything about it, and Athena has had enough. She actually heard a rumor about David leaving a classmate alone after losing a bet, so she takes action and invites David to their place for a friendly card game. David shows up and plays along, curious to see what may happen. Athena proposes a deal to him: if either she or Austin wins, he will have to leave her stepbrother alone. David loves his odds and accepts the wager, beating the step-siblings effortlessly. Athena's plan backfires and she suddenly becomes David's fuck toy. Yet, playing nice to him and sucking his dick won't be enough. David wants to fuck Athena and involve Austin in the equation to teach the step-siblings not to mess up with him.
