Sienna - Going postal

It's her first day on the job, and Sienna does not know the delivery route at all well. In no time at all, she needs to relieve herself and calls base to ask if there are any public toilets on her route. She is told no, and that she'll have to wait until she gets back to the depot. Desperate for relief, Sienna continues working, looking for the next address to which she has to deliver a parcel.Becoming lost, Sienna keeps driving, looking for road names, anything familiar, but she can't find her way. Her desperation is becoming acute, and she tries radioing base again for help. Now there is no reception; She is entirely on her own and hopelessly lost, and her bladder is nearly bursting! Disaster strikes when she starts to wet her jeans, then struggles to hold the rest as she continues trying to find her way. Holding it is now extremely difficult, and soon she is to pull over and climb out of the vehicle before she soaks her jeans.
