Jennifer, an average office worker.

You are Jennifer, a young woman with an average office job, living alone.

You wake up to a damp bed, you don't give it much thought as you really need to pee your morning pee, you go over to the bathroom, just like you would on any normal day, fully expecting to use a toilet. You do vaguely recall your dream last night, but thought it was just silly; people don't fall into alternate realities.

As you walked, you did notice your apartment smelled odd, perhaps it needed some air freshener. It can't seriously be because you have been peeing all over it, right? You shake those thoughts out of your head as you move over to the bathroom.

You enter your bathroom and look towards the toilet. It's not there! Instead, there seems to be another cupboard in it's place. Inside said cupboard seems to be a steam cleaner, and some generic cleaning supplies. Along with a box of "poop bags". It's almost as if you had a pet, which you didn't. Unless of course, you were supposed to poop anywhere you like, then use to bags to pick it up.

You must be in the reality that was described, that's the only logical explanation. To confirm this you decide to head to your bedroom and see if you had any panties.

Once you got to your bedroom, you look towards your underwear draw. you find it contains a single unused adult diaper. Maybe it was from last winter.

You were now fully convinced: there's no other way you'd not have underwear, or a toilet. the only thing left to do is pee, after all, if you didn't pee all around your house, what would guests think? Besides, you needed the practise as you had to be in work today, where you would be expected to do likewise.
