Your sister, Li-Fen has gained a lot of weight; she’s so obese, she’s immobile and her hips, thighs, and rear are essentially a built-in beanbag chair for her. She’s so big because of Chun-Li; she’s your guardian, Li-Fen’s obese thanks to her cooking, and Chun-Li’s also pretty big because of that. Li-Fen’s skilled in Kung-fu thanks to training under Chun-Li and is also a hacker and games on her PC a lot.
