Try to hold it in.
From Create Your Own Story
Peeing right now would surely give your position away. You decide the best thing to do is try your best to hold it in. With your knees still pressed firmly together and one hand pressing tightly against your waterhole, you lifted up your legs and put them up on the toilet seat so no one can see your shoes from outside the stall.
Bam! The loud slamming open of the bathroom door startled you as you almost wet yourself. The deliberate stomps of the pursuing guard echos off the bathroom walls. You hold your breath and try to remain perfectly still as you listen to the footsteps closing in.
As the footsteps grow louder, you press your knees tighter together, sensing the urge to urinate rising with each thump. With one hand pressing tightly to your crotch, you throw the other hand over your mouth to prevent the escape of any unconscious sounds. The footsteps stop, it sounds as if the guard is right outside your stall. You can catch a glimpse of his shadow as he reaches for the handle of the stall...
"Stanton, are you there?" A sudden static sound from his guard radio caused him to pull back before his hand can reach the door.
"Yes, what is it?" He reached for his radio and responded.
"Somebody thinks she might have gone down to the basement garage, we're heading there now. Head security ssays whoever catches her gets first dibs."
"Roger. I'm headed over now." You hear a chuckle, follow by an excited dash out of the bathroom door. The bathroom is now silent again and you drop your palm from your mouth and let out a deep breath.
Suddenly, as if on cue, a warm explosion fills your crotch area. You look down in horror as a dark stain start to form in the front of your skirt. The near escape has caused your body to spontaneously relax, unconsciously releasing the pee that you had been deliberately holding in, soaking your skirt and the hand you had placed there to resist the outburst. You jump up from the toilet seat and watch in horror as warm, yellow streams run down your bare legs and wet your shoes. You hike up your skirt to see that your white cotton panties have been completely soaked by urine. You stood there stunned as a small puddle begin to form around you. You bent down and carefully strip off your soaking wet panties. Pinching it with two fingers, you dangled it in front of you for a second before dropping it into the nearby trash can.
No choice, I still need to get out of here. Now pantie-less, you quickly wipe your legs dry with toilet paper. With a stain still on your skirt, you slowly poke your head out the stall door. Coast is clear, the bathroom is empty for sure. What should you do now?
