"Alright class, that's the end of today. Have a good weekend!" replies the teacher.

That was after ten minutes over the typical class schedule at Fernwood Elementary School. The students took no time at all to rush out of the 3rd grade classroom. Among those two are a cat named Katie and a dog named Molly, both best friends and around the same age of 9. Katie is a light-gray furred cat with dark-gray colored hair on her ear tips and the tip of her tail. Her tail is unusually long and curvy. On her head is a coat of light blonde hair. She is wearing typical clothing including a dark green T-shirt and some blue jeans. Molly is a dog with brown fur and small dark brown spots all around her body fur. The bottom of her face and her belly is white. She has long, droopy puppy ears and a longer than normal tongue. The canine wears a white tank top and khaki shorts with a belt on them. The shorts look like they are containing something inside of them.

"I'll see you on the bus, Katie!" replies Molly. "Okay!" replies Katie. The kitty paces around a bit in the hallway, thinking a bit about the potty since she feels a bit full down there and kind of has to do some business. Katie cannot stand the potty though; only her home "potty" is right for her. The feline suddenly realizes that she is about to miss the bus. The little time she has to take a restroom break is now gone. She has no time to go potty. All her time is now dedicated to catching the bus.

Katie rushes outside the main doors of the school, almost bumping into some students on the way there. Her bus that she needs to catch has their engine turning on. Katie panics a bit, turning into full on sprinting. Her backpack continually shakes and hits her back. The poor kitty feels constipated from the running. She should have went potty. The bus starts to move a couple feet, but Katie manages to get to the bus door, waving frantically at the bus driver. The bus driver opens the door and invites her inside. *pant* *pant* Katie feels tired from the quick after-school rush. She looks for her best canine friend, who waves to her from the middle seats of the bus. Katie walks on over as Molly stands up from her seat. Katie likes to be sitting on the inner part of the seat because she likes the window side. Katie sits on the seat first, with Molly squishing her in a bit sitting near the bus walkway. A small *crinkle* is heard as Molly sits down.

Molly talks to Katie, "Good seeing you, Katie! Was afraid for a minute that you'd miss the bus." The kitty giggles a bit. "Haha, yeah, almost missed it." Molly *sighs* a bit. "Can't believe class ended so late." "Yeah, that teacher talked *forever*." They both nod a bit in agreement. Molly looks up at Katie and asks, "So how was your day?" "Today has been fine~ Got a lot of homework done. The lunch ladies had chocolate milk today! I got so excited and bought two of them!" Molly giggles, "I know how much you like that milk~." Katie's tail wags a bit, but she is also shaking a little bit, trying to shift her seat position from time to time as to get comfortable over something bothering her. Molly gets excited. "Can't wait to go home and play my new video game! I'm glad you're coming along~." "S-Sounds like fun...," responds Katie as she squirms a bit with her hands on her crotch. The struggling kitty is feeling something hot and moist near her butt hole.

Molly starts to notice her best feline friend being strange. "You doing okay?" "Me? U-um... Yeah! Feeling great! Haha..." says Katie as she pretends to laugh, trying to shrug it off. Katie starts to sweat and blush a bit, worrying about her contents down there. As she kept worrying, she looks at her friend with an abnormal look; almost as if she was pleading to be rescued from her condition. Molly gives a smirk on her face. "Gotta go potty again?" Her friend does not reply with a word, just sitting on her furry butt nodding her head up and down like a poor, struggling kitty. "Aww..." Molly replies, starting to rub Katie's back with her paw.

Katie feels a bit of throbbing pain and pressure in her abdomen. The poor nine year old kitty thinks of anything that could ease her aching. With the distance to Molly's home, it'll take longer for her to get to any restroom. Her own home is a bit closer in distance compared to her friend's: about a couple of blocks away. That distance can really make or break the kitty's poor gut. "I wanna go..." "Huh? You wanna go potty~?" Molly questions. Katie feels a bit of aching over that. "I wanna go home meow." The puppy giggles a bit. "We are going home, silly kitty~." "No, my own home."

Molly looks a bit disappointed over that response. "Aw...  I really wanna game with you~ Hold it a bit longer?" "Um..." Katie blushes more, feeling a bit guilty over what she said. Katie looks up, seeing Molly look at her best kitty with free-hanging, droopy ears and cute puppy-dog eyes. Katie shakes a bit, sweating more over what to say. Several seconds later, the confused kitty gives in. "You know I can't resist that. Okay~." Molly gets a bit celebratory on the bus. "Yay! Thanks cutie~." Molly places her right paw on her friend's back, bringing her closer and touching their furry sides together. Molly tightens her arms a bit closer, giving a sort of friendly hug.

Katie responds back with her own paw on Molly's back, but it wasn't as strongly placed as her friend's paw. She still has the hot mess in her gut to worry about. The cat rocks back and forth struggling on the bus seat. Her groin slowly becomes more and more sore, really wanting to release all of it's contents out of the garbage disposal. Her groin is getting all squishy now from the expanded pressure in her intestines. Though fun to poke at, it is becoming very difficult to struggle with. The light-gray haired kitty starts rubbing her groin with her paw. It feels a little bit better when doing that, but the filling inside her body is still too much to bear. Katie thinks to herself, "Maybe I can let some of it out now and just clean up at my friend's home…” She also thinks, “Wait a minute, that's a stupid idea..." She struggles on her ideas between the angel and devil versions of herself arguing against each other. She closes her eyes to mask away the pain of her groin. Then she thinks it over. Eventually, she decides upon herself a decision. She thought of a decent way to resolve her struggling. And that one side of her consciousness is just a lot of fun sometimes...

Her eyes squint shut as she feels something warm coming along. *frrrrrt~* *blort~* A small lump of poop excretes from the kitty's plushy anus. It feels very hot and moist on her furry butt. As the lump is pushed outward, it collides lightly into the pink cloth panties, making the panties bulge a little bit. "Ahhh~." The cute, innocent kitty feels relief and relaxation from some of her pain. It wasn't all of the pain, but it was some of it. She had a thought of letting the pain, and her rectal contents, all go right here, right now. *Gasp!* Katie wakes up in a panic and tries to snip off her lump by closing her asshole shut. The remaining waste sinks a little bit into her intestines. The small lump of shit gets a bit stuck while pushed into Katie's panties, not falling down easily like it should. Her pants have a small "blob" poking out of them where her butt hole is. It also smells a little bit like dirty clothing; probably from her panties being stained.

Katie starts to feel a bit of regret over her choice, but it did relieve some of the pain away. The bus still had ten minutes to go before getting to at least Katie's home. She still had to go poop though. She looks at Molly with a guilty look on her face. Katie knows Molly will figure out what happened eventually, so she decides she needs to tell her best friend. "Um, Molly, I w-went.." *sniff* *sniff* The feminine dog catches a whiff of something. Molly gets a bit excited with a look of glee on her face. Without thinking much, she blurts out to her. "Did you make *poopies*?" "....poop," says Katie as she finishes her sentence. A couple seconds of silence pass by as they got distracted on what the other said. A student or two on the bus overheard and looked around. "Um, Molly..." Katie says in a quiet voice as she pauses for a second while nervous, "...I went poopies."

Molly feels sympathetic for her best friend. She continues hugging Katie close to her side, telling her that everything is gonna be okay. That their houses are coming up in a few. That the poopy kitty should clench her butt for a few more minutes holding kitty poop in. Katie welled up a small amount of tears from her eyes as her friend kept comforting her over the next couple minutes. *lick~* The poor kitty grew nervous during the next couple minutes as the pain started to gradually build up from her temporary high of relief. Her lower tummy ached again. *slurp~* She really needs to go empty all of her contents in the potty. The canine feels her friend's nervousness and troubles. But one question looms on her mind...

"Why didn't you potty before getting on the bus?" asks Molly. *lick~* "Y-Yo-u kn-" Just then, Katie notices something in her mouth. She blushes a bit in embarrassment when she notices her paw inside that she sucked and slurped on the entire time. The light-gray furred kitty is known to lick and slurp her paws under heightened emotions, including in her sleep. Katie takes the paw out of her mouth, looking at it covered in kitty spit. Molly didn't giggle at this or anything since it was a common occurrence. "You know I don't want to use the toilets." "Oh yeah..." replies Molly. "Yeah... Would rather use my litter tray... or my pants~." The dog got a good chuckle out of this, laughing for a couple seconds. Katie replied back with some laughter as well. Katie stops laughing when she starts to actually consider it on the bus since she has used her pants already. Her urges feel worse when thinking about it as she feels and pokes her squishy bladder a bit. Normally, the poopy feline would just poop on the bus if there was no consequence, but she knows everyone on the bus would probably find out.

"Molly, It's painful. I'm not sure I can hold it much longer..." notes Katie. "Silly kitty, why don't ya ever wear a diaper? Then you wouldn't have to worry~." asks Molly. The stressed kitty reclines a bit in the bus seat, feeling worse thinking about garments and humiliation and places to let go in. But Katie feels really tingly around diapers and it made her upbeat thinking about it; but it also really makes her want to let go. She is also fearful of getting caught soiling or wetting in public places or wearing something usually for babies. Molly is carefree about these situations though compared to Katie. While her feline friend stays silent and afraid, Molly continues, "You look so cute when you're all embarrassed like that~. Hehe~." Katie shakes a bit more listening to her say this. "I'm just joking around; you don't have to wear a diaper if you don't want to." The dark-gray tipped kitty *sighs* a bit and replies, "I know... Part of me wants to try diapers but part of me doesn't." Molly wags her puppy tail a bit and notions her friend to come closer. The dog whispers to Katie, "I think it's cuter when you go in your pants anyways~ <3"

Katie feels really shy while looking like a cute, innocent kitty. It's almost as if her friend wants her to poop her pants. "Agh..." The kitty feels some pain in her rectum as the poop tries to escape from her intestines. The only thing against the outside world for it is her clenched butt hole. It feels really hot and moist inside, almost pleasurable even, but the pain supersedes it. Molly notes her friend having trouble and stops joking around. She starts comforting her friend again, rubbing her belly and back as she gives her a close, tender hug. Katie feels a bit off guard by Molly's tenderness, forgetting to clench her asshole as tight. Her anus starts to loosen a bit where the waste starts to make an exit. "Molly. I can't hold it..." Molly pats the kitty's back softly, "Just let it all out cutie~..." She does as instructed as she squints her eyes and starts pushing away~.

*FRRRRTTtttt~* A loud fart is heard as the stinky cat poop starts to exit her anus, *squishing* together with the previous turd. *BLLOOOORT~* "Ahhhhhhh~." Her tail is sticking straight up. A giant bulge emerges in her pants, sticking away from her furry ass. It stays there for a second before being carried down below her butt due to gravity. *frrrt~* *blrrrt~* A second, but slightly smaller bulge pushes out from her butt hole, but it stays there for a few seconds, staining her pants a brown spot before being pulled down. It ended up being quite a load, almost matching the one time she willingly pooped back then before school. The smell of stinky cat poop starts to spread out of her poopy pants to the other seats of the bus. Katie looks half consciousness in relief and pleasure that the aching went away.

Some sounds of clothes rubbing are heard nearby her. *rub rub~* *pant* Molly looks like she is feeling a bit frisky over her friend unloading in her pants, rubbing her crotch back and forth. "Ahh~." *pant* Molly's tail is swagging quickly back and forth. Her mouth is open as she pants in pleasure. The bus starts to strongly smell like Katie's litter box. She really likes the smell of kitty poop around her as well. She gets off at such a young age. *slurp* Molly feels something going on down there.

*suck* *sniff* Her friend, Katie, on the other hand, stopped relaxing and came back into a conscious reality. Tears start to roll down Katie's eyes as she sucks her paw thumb like a little baby. Her face is all beet-red from the stress of holding shit in. Her pain is gone, but the fear of humiliation in her mind remains. *sniffle* Katie moves around a bit to try to get the lump of poop off of her. *squish* *smurrsh~* But that ended up making her messy situation worse; making her feel terrible as she thinks of cleaning all of that up. She couldn't take it anymore... "Wahhh!" Katie wakes up from her fapping as she heard her best friend burst into tears. She tends to her friend.

"Aw... don't cry; everything is over now... You did a good job. We're at your house meow, just one more stop." says Molly. Molly gives Katie a bear hug. *sniff...* Katie stops the waterworks and starts to calm down. *pat pat* A heavy paw is felt tapping Katie's back every second or so, as if Molly was trying to burp the baby. Molly then gives her feline friend a nice *smooch~*. The kitty's face has some saliva all over her lips, but the kitty didn't try to wipe it off. In fact, she kind of liked it being there. "Feeling better?" "Y-yeah.." Katie take some deep breaths.

"Oh man, what's that rancid smell!?" cries one of the students. The conversations on the bus start to increase in volume into an outright chatter house. Complaining is heard on the bus as the side windows were opened, letting the litter box air out a little. The bus driver in the front as he drives with one paw on the wheel and one on his nose moans "Oh no, not again..." The bus slowed down a little bit before arriving at Molly's house. "Be *QUIET*, kids. It'll go away soon." The bus *screeches* to a stop and then shortly after opens the bus doors. The students lowered in volume but not into a halt.

Molly gets out of her seat and whispers to her friend, "Stay closely in front of me". Katie is not sure what is going on, but agrees to it. They both slowly and closely walk towards the front bus exits. Katie is seen with poop stuck on the ass of her pants, but it's a bit hard to notice. Maybe that’s why Katie is in front... They almost reach the doors until a student notices the shit-stained pants. "Poor kitty is scooping her poop again~." The students start to laugh at the poor poopy kitty. This isn't the first time this has happened either: she has a reputation for this kind of thing. Katie tries to block out the humiliation as she reaches the bus exit. The hippopotamus bus driver looks at them and says, "You really should use the restroom beforehand." The bus starts to close the doors after the two friends leave the bus. Katie's poopy butt is shown towards the students in the bus as they laugh and make various funny faces towards her. The bus slowly drives off on its way.

"Don't listen to them. We're home now~ And you will always be my cute, stinky kitty friend~." Katie is faced against the licking of his canine friend giving her some slurps and dog spit on her face. "Hehe, stop that! I'm okay!" Molly smiles at Katie as they both wag their tails. "Let's go inside and get you changed in some new clothes." Katie nods her head in agreement. They walk to Molly's front house doors. *zip* Molly opens her backpack as Katie *knocks* on the door. Molly looks like she is getting something from the backpack. Molly's parents open the house doors happy to see them and invite both of them in. Katie smiles at them while slightly rubbing above her furry butt a little bit and starts to walk in. Molly giggles a little bit as she walks in behind her. As the door closes, Molly is seen with two pairs of diapers in her left paw.
