Imagine, A and B both go to a carnival right? As a cute little date, a kinky date. because of A's horrible potty track record they're wearing a diaper. B is the one who had them wear it, and A being the person they are, keep getting distracted by this ride and this game and keep getting sodas and waters from the food court.
The two are on a carousel, and even though A is in a diaper they're embarrassed at the fact they can't hold it for long, so they tried to hold it as long as they could so they could prove to B that they didn't need the diapers.
But on the carousel, A's need just hits an all time 10. The way it keeps moving, they're Lover (B) right on the horse next to them, the fishbowl game that A can see.
It's all too much, and suddenly a small spurt of pee jets out into they're diaper, being absorbed by the padding.
A makes a small whimpering sound, they're face flushed a bright red.
They feel another squirt jet out.
The way the now slightly damp diaper feels against they're lower parts, the way the carousel is moving. The way that they have to go so bad.
A in there Desperation starts to subtly grind on the carousel horse, rocking they're hips back and forth slowly, trying not to go to fast because they are in public, but also trying they're damned hardest to hold it.
"You okay A? You keep squirming" B said thoughtfully as they stare at A, gripping the horse so tightly that they're knuckles are white
"M-mhm!" A said as they blushed, they're need ever growing. Another spurt into they're diaper, the grinding intensified.
B stared at them again, running their brain through the possibilitys.
A was squirming, blushing, had drank a lot, hadent been to the bathroom-
B smirked slightly, this was gonna be fun.
Soon the ride stopped, A kept on slowly grinding on the horse, wanting more. Feeling themself get aroused at the grinding an wetness in they're diaper.
B grabbed A's hand and tugged them off the ride and along to wherever B was going, but the sudden movement caused A to leak again, a longer leak this time.
A stopped suddenly and whimpered, they're face red as the crouched down slightly, trying to subtly hold themselves.
B knelt down to them and lightly tilted A's head so they were looking at them.
"A. I know you have to go, but just hold it a few minutes longer okay? Can you do that? Can you make it a few more minutes?" B asked as they looked A in the eyes.
A reluctantly nodded, their eyes teary and their cheeks pink. They slowly stood up, and as soon as they did, B took them and the two started speed walking down too.... Somewhere
B took A to an area behind a building, it was private. They're was no one around.
As soon as the two were back there, A immediately slammed their hand to their crotch, bouncing up an down as they did their best to hold it all in. Whimpering and moaning.
B sat down on a nearby chair, spreading their legs an bringing A over to sit on their lap.
A wasn't dumb, they knew what B was doing. But boy oh boy they didn't mind. Not one bit.
A wrapped their arms around B's neck, grinding quickly and hardly into B's thigh.
"Mm~ fuck babe~" B whispered as they started biting and licking A's neck.
B's toungue didn't make it any easier to hold.
"I- I hav to go- so badly B, so badly." A said as they whimpered agasint B.
"Hold it doll, keep it all in." B whispered into A's ear before going back to kissing their neck.
A grinded harder into them, faster, the friction causing them to be wet in two ways.
Another spurt of pee leaked out, and another, and another, soon, A was full on pissing their pants, still grinding.
The diaper swelled agasint A's nether regions, yellow tinted and warm.
The warmth felt so good. A kept grinding.
The accident they just had was enough to turn them on so much that they came, cumming straight into their soaking diaper, they're body tensing and releasing as they moaned.
A panted lightly as they diaper squished agasint their parts, leaking a small dribble into their pants.
B smiled and kissed A's forehead.
"Wanna head on home hun?" B asked them.
A nodded, they're blushy, wet, sticky, teary, horny self wanting nothing more than to be home with B.
"Y-yes please." they said as they got up, the diaper leaking into their pants more, a noticeable dark patch on their inner thighs.
"Good. Make sure to play with yourself in the car too, I don't want to stop seeing you like this." B said as the two started the walk to the car.
A nodded an followed behind, wet sticky and horny.
