Both girls are desperate to pee. Both girls are subtly shifting their positions but cannot move a lot. she is shifting positions due to desperate to pee. she kept her hands between her legs and trying to hold pee. Her hands kept holding her crotch during the whole time. Both girls are shipping and squeezing their legs together. Keep their facial expression steady, and do not over-express. Keep their eyes half closed, and showing painful and worried expression on their face. Keep the camera angle steady. One girl whispers to the other in a worried voice "我好想尿尿..". Then, the other girl whispers "我也是。。奶茶喝得太多了。。"
