You have been driving for miles, your bladder is filled to the brim, the weather is really bad outside and you're running out of gas.
You haven't peed since the night before, the whole day was such a rush and your bladder is begging for relief.
You're forced to pull over in a neighborhood and try and get some help with your car as it is breaking down in real time. (or perhaps use a restroom)
You knock on the door to the nearest house, and you are greeted by a very kind individual. They immediately invite you into their home and listen to your plight. They feel so bad for you that you have had such a bad day. They especially sympathize with your ever expanding bladder that is just waiting to empty.
As kind as this person is, they don't lead you to the bathroom, so you assume you aren't allowed to use it to be respectful. Despite your bladder about to burst, you will not pee in someone's toilet without explicit permission.
This person feeds you and gives you plenty of fluids to drink. They are so generous and give you neverending refills of your favorite drinks.
After nighttime hits, they order you to go to bed. They insist that you listen to what they say until the storm blows over.
The bedroom they put you in is a big and comfy bedroom with lots of games, books, and toys. There is also a bathroom attached to this bedroom. You instinctively thank the owner for giving you a place to stay during such a tough moment in your life.
They giggle at your appreciation and get you into comfortable pajamas. Its as creepily intimate as you think it is.
They give you a hug and a kiss and send you to bed. They close the door and lock it from the inside out so you cannot escape.
As you inspect the bathroom attached to your bedroom, you feel like you're about to explode with a presumed toilet nearby.
To your horror, this is a fake bathroom. There is no toilet in this bathroom at all. The shower is padlocked so you cannot relieve yourself in there either. The sink is practically nonfunctional. Its much too high to climb over without peeing all over yourself from the contortion you have to do. There is also no inverted dome shape on the sink, it is entirely flat and the running tap would make a mess.
Tears start welling up in your eyes as your intention to pee is halted by this fake bathroom.
You walk up to the bedroom door and jiggle the doorknob to try and open it, you unfortunately realize that you are locked in and must hold it.
Even in this helpless state, you still don't want to wet the floors or furniture of this kind person's home.
You lie on the bed and hold your crotch as tightly as you can.
You last the night and you managed to not wet yourself, but your bladder is fuller than ever. It is bulging out of your stomach and it is throbbing intensely.
You have no idea what to do and then you hear the door unlock. The kind individual returns and sees you in your vulnerable and compromised state.
"Now I don't want to freak you out, but having you here has made me the happiest I've ever been. I really do love taking care of sweet and obedient subs like you!"
You are in complete shock, why would this person outright admit this? Especially when you're so vulnerable and at their mercy.
"I'm going to be your new owner now, and life is going to be a little different!"
The person has such a sinister smile on their face while giving you the horniest gaze you've ever seen.
You don't know if you'll ever see relief again.
(Tbh i wanna make a part 2 to this lol)
