Karen (Christina's name in this story) is on her way to investigate a suspicious insurance claim made by a John Carson.  She gets lost en-route to his house and battles the urge to pee in the car.  When she arrives at Carson's residence, she asks to use the bathroom.  Instead of letting her go, he grabs her and ties her up in the basement.

Carson keeps Karen bound despite her repeated requests to be allowed to use the bathroom.  She makes several attempts to get free, but her situation in hopeless.  After being made to drink water, Karen is eventually forced to wet herself.  Carson is furious about the mess, and after finding fresh clothes for Karen from his ex-wife's closet, he takes her out into the woods and ties her to a tree because he is expecting company.

Left unattended for some time, Karen eventually needs to pee again and has to let it go in the jeans she has been given to wear.

Real Estate Agent Rebecca (Christina's name in this story) is showing houses to a Mr. Smith, a rather fussy client who is very particular about the kind of property he wants to buy.  Rebecca, who needs to pee, tries to encourage Smith to at least look inside some of the properties they visit so that she can use the toilet.  Smith refuses.  After showing him several houses Rebecca drives to a mall, ostensibly to buy coffee but in reality to find a public lavatory.  When she fails to locate one, she is forced to return to the car with a full bladder.

When, finally, they arrive at a house that interests Smith, Rebecca discovers that the code she has been given for the lockbox will not work, and again she is unable to get inside to pee.  Now desperate to go, she calls her office to get the correct code for the lockbox, but no one is able to help.  Struggling not to wet herself, Rebecca starts driving to the last showing, praying that Smith will want to go inside so she can finally do something about her bursting bladder.

Before they reach the final property, Rebecca is overcome with desperation and has to pull off the road onto a woodland track.  Just before she gets out of the car, an irate Smith handcuffs one of her wrists to the steering wheel and storms off, angry that she has wasted his entire day.  Unable to wait any longer, Rebecca is forced to stand just outside the car and pee in her skirt and pantyhose.
