Bored of playing games, his brother switched to "playing" my little sister

Two brothers, Sean and Kristen, played games together, the older brother playing in the living room and the younger sister lying on the bed in the bedroom. After a while, Sean began to feel bored, the boy decided to go to his sister's bedroom to announce that he was not playing this game anymore.
But then after meeting his sister wearing a sexy and cool outfit, Sean started to think of a new game and his sister was the main character.
