Crap, Sofia Su could really use some extra cash right now. Turns out her stepbrother is a bit of a gambler and she decides to take advantage of that. She wins a few times and perhaps gets a bit too confident. She takes on a big wager and loses. She tries to bargain to get out of it and that's when her stepbrother suggests they get down and dirty. Sofia is hesitant at first but she doesn't want to give him the money. Turns out this was a great solution since they both enjoy fucking each other a lot!
