Good son: wait until someone else tries to beat her
From Create Your Own Story
A young boy steps forward challenging her for 5 dollar. They both take their seats and start playing. The boy is pretty good and the first game is extremely close. Your sister barely pulls through and beats him. It´s a best of three, so Laura needs one more win to win the money. The first half the boy pulls ahead quite a bit. Laura being scared of losing money now is forced to use her signature move.
She leans forward and sticks her ass out. The last few times you saw her playin she was always wearing long, tight jeans. Today though she is wearing hot pants. As soon as she moves forward, not only making her ass crack at the top pop out a bit, but also make her asscheeks look out from the buttom of the pants. Nobody is any longer focusing on the game anymore and just stares at her peachy butt. Even you, her own brother now only has her perfekt back on his mind. You don´t even realise your sister won the game until a few seconds until it ended because you were fantasizing about touching her indecently.
She takes the money from the poor boy and asks if someone elses dares to try and challenge her.
