You and your girlfriend have been driving down the road for the past few hours on your way to a convention. You noticed she had put a plastic cover on your seat. You weren’t sure why exactly but you knew it must mean she had something fun in store for you. You realize that you need to use the restroom.
“Hey can you pull over at the next exit? I need to pee.”
“Yeah, of course” she responded, and you returned back to the idle chitchat. A few minutes go by and you see an exit with a gas station. She drives right past it.
“Hey, you missed that exit.”
“Oh, did I? Silly me.” She shot you a mischievous grin. Your mind started racing as you realized why the seats had plastic covers on them. You had told her about this, but only as a fantasy. You didn’t think that she would actually do it. Your heart skipped a few beats, though you weren’t sure if it was nervousness or excitement.
“Hey, vibe check?”
You briefly consider calling your safe word. But then you consider how hot it would be. You’d be giving her complete control over your bladder, and by extension your most basic of needs. Without another thought, you shout “green light”.
“Then let the fun begin. I haven’t yet decided how long I’m gonna make you wait”.
And with that, the battle starts.
The first ten minutes fly by easily, but then it gets harder. You finally start to break and ask “How long until you’ll let me use the toilet?”
“Not long now, just a little bit longer to wait”
You start to squirm as the pressure builds up. You really have to go. You ask again. She gives you the same response. This repeats for a while as the pressure builds up. Your whole body is squirming just to try and offer any recourse from your bursting bladder. You ask again and again, and again and again she tells you its just a little bit longer.
Finally, you come to a realization. She has no intention of ever letting you get out and relieve yourself properly. She is trying to make you piss your pants, and it looks like she’s about to succeed. But you’re stubborn. You are going to hold it until the very last second in the hopes that out of pity, or because she’s impressed, or just because she’s bored, she’ll save you from this embarrassment. You know that’s not going to happen, but it can’t hurt to try. You take your phone out of your pocket and set it on the dash, just in case. You beg her to pull the car over, you’d even take peeing on the side of the road. Hell, you’d be willing to piss in a bottle, exposed, right in front of her , if it meant saving your dignity. But no matter how much you beg and plead, she gives the same response. Just a little while longer.
Finally your mind gives up and your body takes over. You feel an immense relief as the pressure finally starts to go down. A wet spot forms in your pants. It grows and grows and keeps growing until your entire crotch is soaked. You feel it run down your legs and into your socks. It runs onto the weather protector on the floor and collects in the gutter. You even feel it squish up your back. She lets you soak in a puddle of your own mess while she takes her time finding an exit with a secluded gravel road to clean up on.
But before you can clean yourself up she turns to you.
“How adorable. My little slut just couldn’t hold it in. They made a huge mess all over themselves. That’s so cute. I’m gonna take a picture of my pathetic little slut and send it to all of their friends.” She was referring to a group chat that you were both in, with a couple of other kinky people in it who would love to see the pathetic piss-covered state you’re in right now. She turned to you and whispered almost silently so as not to break the mood. “Vibe check?”
All of your brainpower right now is going towards how hot it would be for the whole group chat to see you like this, a slut so pathetic they couldn’t even control their own bladder, but you just manage to recover enough brain cells to squeak out “green light”.
She takes a picture of you. You see it roll in on your phone, you in your full glory sitting in a puddle of your own piss, so horny that the look on your face makes you seem almost proud of yourself. The caption “looks like our little slut had an accident”. She strokes her cock while making you sit in your mess for just a few more minutes while the replies roll in on your phone.
“Way to show the bitch their place”
“Lmao pathetic slut”
“~~i wish that was me~~”
“worthless slut can’t even get through a roadtrip without pissing themselves”
“They enjoy it too! What a slut”
And so on. Finally, after about 10 more minutes of this, when your piss had gone cold, she tells you its time to clean up. You carefully remove the seat protector so the liquid on it falls onto the weather protector. You pour the weather protector itself into the gravel. You strip naked. You grab a towel out of the trunk and dry yourself off. You remove your sweatpants and an old black t shirt from your suitcase and put it on.
“Now” she said. “Let’s get to our hotel so we can clean you up, and then I’m gonna reward you for being such a good little slut”
