In this one, we get Kajira to wait until she is at bursting point, and when she can't hold it any longer she will lift her dress, pull down her panties and squat. At the moment Kajira decides she simply has to go, she is asked to pull her skirt back down and wait a bit longer. The look of anguish on her face betrays how she feels about that but she does it anyway. She struggles hard to control her bladder until she truly can't hold it any longer. Her pee gushes out in a fast stream when she releases.
