Part 1



BEEEP BEEEP BEEEP BEEEP BEEEP

The oven timer alerted Serena that it had finished heating up...

“Great, it's ready.” :D

An adorable sheep girl comes over to open it, her enormous breasts covered by her apron and her little tail wagging happily. When she pulls out the rack, all she sees is a charred black layer on the mold.

“Ohhh, not again.” D:

After an hour of trying hard to do things right, unfortunately, the cake she was baking was ruined.

CLAP CLAP CLAP

Through the double doors, after coming down from the second floor, a dog enters that can barely fit through the doorway due to its gigantic rear end, hips, and thighs. It's Dylan Dalmatian, unusually large as a permanent effect of certain pills he took some time ago for a special occasion.

“H-hello Dylan, how...”

The dog interrupts Serena by pointing his rear end at her and letting out a loud PGPFPFPPFPFPF right in her face while her mouth is open.

Dylan yawns and rubs his eyes. “Good morning, Serena.” The storm hits mercilessly, she can't close her mouth because of the force of the wind, which pushes down her throat into her stomach, burning in every corner.

“We have a big order of donuts today, we might be here until night and...”

SNIF SNIF

“Hey, something smells burnt, were you cooking?”

Dylan's gas stops to free the girl's mouth.

GULP The gas is so thick that Serena swallows by reflex. COUGH COUGH COUGH

“Ahg, I still can't get used to your way of greeting me... *COUGH COUGH* Ah, yes, I wanted to make a cake.”

“But it didn't turn out.”

“No...” The girl looks down, embarrassed. “I don't understand what happened. I followed the recipe's instructions for time and temperature.”

“Let me see.”

The dog went to the back where the recipe books are kept and looked the only book that was open, the cake book, and immediately realized his companion's mistake.

“Haha, I see what happened. The oven is in Kelvin, the recipe is in Fahrenheit.”

“Ooohhh, I see...”

“You don't know what that means, do you?”

“No,” she said, embarrassed.

“It means you set it to almost twice the heat.”

“Oh. I ruined it again.”

Serena sat down on one of the chairs with a very sad face.

“Ah, come on, you'll get it right next time.”

The girl just responds with a sigh.

Dylan stares at her for a few seconds. She's not only his coworker, she's also his friend, so he had to think of a way to cheer her up. And the big smile that began to form on his face showed that he had a very good idea for doing so.

“Heyyyyy Sereeeeena. Look back here, look at my butt.”

Dylan turns around again, pointing his gigantic ass at her. WOBBLE WOBBLE And he starts wiggling it while saying, “I just thought of something that will make you happy.”

“Dylan, that’s always fun, but right now I'm not in the mood to watch you shake your butt.”

“No, it's not that. Open your mouth as wide as you can. You'll thank me when I'm done.”

Dylan brought his butt close to Serena's face, so close that she could smell the strong rancid stench it emitted.

Serena, very innocent, unsuspecting of Dylan's intentions, did as he said, opening her mouth without guessing what the obvious result would be.

“Good girl, here's your prize. A fart-swallowing session just for you.”

Dylan pressed his butt against Serena's face again and the farts returned.

PPPPPPPPPTTTTTTTTTTTTTTTTFFFFFFFFFFFFF!

Now, with all the gas entering her mouth, Dylan pushed his butt even further, pushing Serena's head deep between his buttocks, which, combined with her opening her mouth as wide as she could, caused her lips to seal Dylan's anus perfectly.

“See?” FFFFFFTTTTTTTTTTTTTTTTTTPPPPP “What did I tell you?” PPPPPPPPPPFFFFFFFFFFFFFTTTTTTTTTT “You must feel so good with your mouth full of my farts.” PPPPFFFFFFFFFFFFQQQQQQQQFFFFFFFFF “Going down your throat.” BBBBBBBBBBFFFFFFFFHHHHHHHH “Until it reaches your stomach.” FSSSSSSHHHHHHHLLLPPP “I told you this would make you feel better.” BBBTTTTRRRLLLLLLSSSSS “Here, have another one.” PPPPPRRRRRRRRRPPPPPPPPPP “Yes, no one can be sad when they're my gas filter.” FFFFFFFFRRRRRRRRRRRQQQQQQQ “Ahhhg, get comfortable because there's more coming, much, much more.” BBBBBBRRRRRRRRAAAAAAAPPPPPP “Serena, you'll swallow my farts and feel great.” PPPPPPPPPPFFFFFFFFFFFFTTTTTTTT “Don't be embarrassed to swallow my farts, you're a very good partner, you deserve to swallow all my gas.”

This constant storm lasted about 20 minutes, with Serena being forced to swallow almost 500 BLASTS.

“I think that's enough... Wait, one last one and that's it. A big one, you're going to love it.”

FFFFFFFRRRRRRRRRRRRRTTTTTTTTTTTPPPPPPPPPPGGGGGGGGGBBBBBBBBBB!!!

“Ahhh! That was a good one, I'm going to let out another one just like it, you know, for you.”

BBBBBBBRRRRRRRRRRRRAAAAAAAAAAAAAAAAPPPPPPPPPPPPPPPPPP!!!

“Ohhh yes... Now for real, one last one, I want to let out another one.”

PPPPPPPPPPPPPPPPPPLLLLTTTTTTTTTUUUUUUUUUUUUUUUGGGGGGGG!!!!

The dog took a step forward, leaving Serena free from his rear end, sitting with her mouth open, a column of dense, toxic gas coming out of her mouth, and her eyes rolled back.

“So tell me, my new living gas filter, did swallowing my farts make you feel better?”

GULP, Serena swallowed what was left of the gas in her mouth and shook her head.

“Well...”

“Admit it, it was nice being my fart filter. You even want to swallow more.”

“I...”

Dylan puts his ass back on Serena's face, leaving enough space for her to speak, and says, “Just say it, you want to swallow my farts, say it.”

The girl obeys and says in a playful tone what Dylan ordered her to say.

“I want to swallow more farts.”

“That's right. I know you'd rather use your mouth to swallow my farts. You're a very pretty girl, pretty girls love my farts.”

Serena giggles.

“That's what I like, seeing my friend smile. You're my pretty little gas-swallowing sheep.”

“Okay, okay, *sigh* you always know how to cheer me up. Thank you.”

“Thanks for... You know what I want to hear.”

“Haha, okay, okay, thanks Dylan for making me swallow your farts.”

“Very good! Good girl.”

Dylan moves his butt away from Serena.

“So why were you so sad? It's not the first time you've burned something.”

“I know... I just wanted to make something special... It is for my birthday, and ever since I was a kid, I've always had chocolate cake for my birthday. It's today.”

“Really!? Why didn't you tell us? We would have prepared something for you.”

“I, um, well...”

“Didn't you think of it, or did you forget?”

Serena looks away, blushing, and Dylan covers his mouth to keep from laughing out loud.

“Don't make fun of me!”

“Haha, sorry, sorry, it's just that sometimes you are a little silly.” The dog goes to the oven. “I have an idea. Let's do our work, and when we're done, I'll give you lots of presents.”

Serena stands up, “Okay, let's do it.”



Part 2



After several hours of work, about 200 donuts were baked, glazed, and packaged.

CLINK

The notification on Serena's phone announced that it was lunchtime.

Serena finishes taking out the last tray they had made. “Just in time.” She removes her tablecloth. “Do you think we'll be done by the afternoon?”

Dylan puts the ingredients aside and stores the donuts they had already made. “There aren't many left, we'll probably be done by 3 or 4.”

“Wow, we have a lot of work to do today.”

“Yeah. But we'll worry about that after we eat.”

“Where are we going today? How about some pizza?”

“We're not going anywhere. I made lunch. I made something special for your birthday.”

“Ooooh, cool.” ^o^

The girl goes to the second floor of the bakery. There is her room, Dylan's room, and a large balcony with a great view where they often eat from time to time at the table that is fixed in the center.

A few minutes later, Dylan also came up with the food. A large bowl with 3 kilos of spaghetti with lots of cheese on top, a cat-sized plate of caprese, 2 kilos of risotto, 30-layer lasagna, and about 15 pizzas with different meats. He had to go up and down a few times, as he couldn't carry everything in one trip, especially with paws instead of hands.

After putting the food on the table, Dylan also climbs onto it so he can serve the food. On his plate, 90% of the food, and on Serena's, the rest. And it's still more than anyone else eats. Serena is lucky that almost everything is distributed very well where it suits her best.

“It looks delicious... Hey Dylan, you didn't bring any cutlery.”

Dylan uses his paws to spread his buttocks apart. “You won't need it today.” He sits on Serena's plate.

BRAAAAAAAAAAAAAAAAAAAAAAP

The food would have flown off the table if the dog's big, fat ass hadn't been on top of it. When he got up, there was no food left, it was all between the dog's soft buttocks.

“You'll have to eat from here.” Dylan slaps his butt and lies down on the table, putting his fat ass like buns to eat. “This is another one of your gifts. Just open your mouth, and I'll push the food in.”

The hungry girl didn't hesitate to obey, sinking her head back into the dog's rear end, her mouth open.

PPPLLLLLFFFFFFRRRRRRRPPPPPPP

The food tasted completely different, the toxic gas completely combining with each morsel.

She felt Serena moving her mouth to chew and swallow on her buttocks, and as soon as she opened her mouth again, FFFFRRRRRRTTTTDFRDFFFDDDDDDD to put more gas and food in her mouth.

“And when you're done, I have two more gifts for you.”

In that position, Dylan farts and eats equally.

PPPPPPPPPRRRRRRRRFFFFFFFFFFFFF

FFFFFFHHHHHHHSSSSSSSTTTTTTTTTT

LLLLLLPPPPPPPPPUUUUUURRRRRRRR

The farts continued even when there was no more food. Dylan just kept farting in Serena's face nonstop. And she, with her mouth open, unable to close it because of the force of the farts.

BBBBBLLLLLLLLLAAAAAAAAAAAAAAAAASSSSSSSSSSTTTTTTTTTT!!!!!

One last fart knocked the sheep out from between his buttocks, throwing it onto the balcony floor. Dylan turned and leaned over the table.

“Now that you've finished your meal, are you ready for your first gift?”

GULP “Ah... Uh, sure.”

Before she could get up, Serena saw Dylan move back, out of her sight, and then reappear, jumping straight on top of her.

SLAM

Dylan fell sitting on her face, causing a crash that, by pure luck, didn't break the floor. Perhaps thanks to the softness of his butt.

Once again, Serena's mouth was sealed against Dylan's anus.

“You loved the first one, so I'm going to give you another session of swallowing my farts. Be a good girl and swallow them all.”

The humor in that sentence was its irony, because as soon as the next PPPPPPPPPPFFFFFFFFRRRRRRRRRRRR came out, no one has enough strength in their mouth to resist.

BBBVFVVVVVVVFFFFFFFBB “And this time, I'll let out a lot more.” SSSHHHHRRRRRUUUUOOOOPPP “Isn't that great news!?” PPPPPPPLLLLTTTUUUUUUGG “You're going to swallow a lot more farts.” FFFFFFRRRRRRRTTTTTTTTT “Like this one.” TTTTTRRRFFFFQQQQQQ “Or this one.” TTTOOOOOOOOOOOTTTTT “And especially a lot like this one.”

Dylan leaned over, WOBBLE WOBBLE his butt a little to get ready.

BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA ASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT!!!!!

That was the strongest and longest fart Dylan had let out in months. Ten uninterrupted minutes, enough toxicity to poison an entire lake, and enough force to destroy several blocks of buildings.

“Wuah... Hehe... that felt amazing. And I bet you loved getting it too.” SLAP Dylan slapped himself on the butt. "I bet you didn't know my ass could do that, I think it's the first one you've ever gotten... Anyway, let's keep going, you still have a lot more farts to swallow.

BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBRRRRRRRRERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP!!!!!

The second fart-swallowing session lasted about three hours. That much gas would have been enough to cover the entire planet, but instead it ended up concentrated inside Serena, swelling her stomach a few centimeters.

Without wasting any time, Dylan climbed back onto the table, leaving Serena on the floor, her mouth once again like the crater of a volcano, releasing a dense cloud, breathing somewhat heavily.

Every time she exhaled, more gas came out.

“Don't just lie there, come and get your second gift.”

“Give me *COF* a second. *COF COF COF*”

GULP, as she swallowed, all of Dylan's farts remained in her stomach, their burning and stench permeating her system.

Dizzy, she tried to get up, staggering and stumbling, the farts frying her brain as if she had drunk several glasses of wine.

“It's time for dessert, a chocolate cake just like you wanted.”

“You really made one for me!? Awesome!”

The sheep's tail wagged happily again. She held onto the table to get up and, with a push, made her way to the chair to sit down and eat her cake.

When she looked up, what she saw was Dylan's butt again, pointing at her.

“Sure, chocolate cake is on its way.”

PUSH

The dog began to poop, letting out a giant log onto the plate. It's thicker than Serena's entire body, and as it falls, the sound it makes shows that it's quite heavy, and it looks very hard, so much so that it hasn't even stained the tablecloth.

Dylan stopped pooping without pulling it out completely. Only a meter of the log is on the table.

“Here you go, I pooped a slice of chocolate cake just for you.”

Without a candle, that would be dangerous.

“Awwww, thank you so much Dylan, it looks delicious.”

“Of course it is, come on birthday girl, eat my poop.”

“But Dylan, you didn't bring any cutlery, how am I going to eat your cake?”

“Same as my farts, just open your mouth and let it in. You've had plenty of practice.”

“Okay.” :D

With her mouth open, the sheep brings Dylan's poop close to her face, putting as much of the log as she can in her mouth. She tries to push, stuffing as much as she can inside, but it's just too big.

“I'd better help you a little.”

HHHGGG

Dylan pushes harder, shoving more of the log in, finally getting it into Serena's mouth, stretching her mouth, marking a direct path that bulges and stretches to make its way to her stomach, where only the tip of the log leaves it completely full.

But a full stomach won't stop this dog's ass, he keeps shitting, stretching Serena's stomach with more and more chocolate cake.

“Maybe you want to get on the table too.”

He stops shitting, leaving the trunk of his ass at Serena's mouth motionless, like a bridge that cannot be cut.

She, with all the weight of the poop inside, gets up with difficulty, puts one leg on the table, leans on her arms, then the other knee, and stays there on her knees.

“Remember that trick you tried to teach me? Down.”

Even with the log in her mouth, Serena leans down until her head is on the table, pushing the log in a little further and lying face down.

“Perfect, much more comfortable.”

Dylan shits again, pushing his log further into Serena.

For a long time, the sheep was internally devastated with tons of hard waste that she couldn't even chew, only swallow and enjoy the taste.

Finally, she saw the big butt from which this dessert came out approaching her. And with her mouth already open from the log, it wasn't very difficult to put her anus in the sheep's mouth. This was the end of the log.

It seemed endless, half an hour just for a single log of poop that kept coming out and stretching her stomach. Serena now had a mountain of waste inside her, which meant that her stomach looked about 15 centimeters bigger on the outside.

“How did you like that slice of cake, birthday girl?”

BBBBBBBLLLLLLLLLAAAAAAASSSSSTTTTT

A fart in her mouth prevented her from responding immediately.

“Oh, it got away from me.”

PPPPPPPPFFFFFFFFFFTTTTTTTRRRRRRRRR

“And another one. You know what? That moved my bowels. I hope you want more cake.”

Dylan pooped again, a second log of chocolate cake pushing the first one in and taking its place in her mouth and throat.

“I guess at this point, you'll love being my toilet. Yeah, it's a good idea, I know, when you finish your cake, I'll give you another present.”

A muffled, choking sound came out.

“Oh, didn't I tell you? I made you a whole cake. I'll poop out every slice for you. You'll be a good log-swallowing toilet.”

Saying that, Dylan turned to look back over his shoulder. Serena was wagging her tail at the thought of getting more chocolate cake.

“That's right, good girl. Swallow all your cake.”

Each log was a slice of this delicious cake served by the dog's intestine. To eat the whole cake, Serena spent five full hours lying on that table, receiving tons of poop nonstop.

“Aaaaggg, I feel lighter, how about you?”

BBBBRBBBRBRRRRRRRRTTTTTTLLLLL

Dylan got up after letting out the last fart to make sure he pushed the last log and that it stayed inside Serena's stomach.

Serena couldn't respond, she was on the verge of passing out. Her mouth was open in a smile, her tail wouldn't stop wagging, her legs and arms were shaking, and her eyes were completely white with tears falling.

Seeing this, Dylan blushed and let out a small laugh.

“Awww, what an adorable toilet.”

Once again, Dylan settled his big butt on Serena's face, but this time not with his anus in her mouth, but in her nose.

“Wake up, sleepyhead, you still have a lot more poop to swallow.”

BBBBBBRRRRRRRRRRAAAAAAAAAAPPPPPPPPPP

The toxic gas entered her system again through a different place, calling out and burning her lungs. This was the equivalent of a full-body shock, bringing the girl back to consciousness with a jolt, and the first thing she saw was Dylan's butt rising from her face.

“Ahh! Dylan, what happened?” She increasingly notices the taste of poop in her mouth and the burning of the gas in her lungs. “Oh, haha, I remember now.”

With difficulty, Serena gets off the table, and standing up, she can see how her stomach ends up inflated just enough to lift her shirt halfway up her belly.

“Wow, that was a lot of cake, it was delicious. Too bad it's all gone.”

“You think so? I saved the best gift for last.”

Dylan also gets off the table and, wiggling his fat butt, starts walking inside. “Follow me.”

“Sure.”

The dog led Serena to his room.

“All right, lie down on my bed.”

Serena blushes deeply. “Wait! Dylan, you and I aren't even dating.”

“What? Oh, no, we're not going to have sex.”

“Oh, *sigh* I was worried.”

“Hey!”

“Sorry, I didn't mean that. I meant we've never been on a date or anything, I mean, as friends, since we've only worked together for a long time and I...”

PFFPPPPPPPPPPPPFFFFFFFFTTTTRRRRRR

A fart right in her face stopped Serena before she spent several minutes trying to explain herself.

“Relax, I understand what you're saying, now let's get to your gift.”

“Okay.”

She lies down under the sheets as if she were going to sleep.

“Not like that, up there, like you were before on the floor.”

“Oh, right.”

She turns around and pulls back the sheets.

“Like this?”

“Perfect.”

For the last time today, Dylan gets on top of Serena, pointing her butt toward her face, with her hind legs on either side of her head and her front legs standing on her large breasts.

“Guess what your gift will be.”

“Mmm...”

“Let me give you a hint.”

PPPRRRRRRRRFFFFFFFFFFTTRRRRRRR

“Dylan, your noisy butt didn't let me hear the hint.”

“Maybe you need another hint. Open your mouth.”

“Okay, aaaahhhhh.”

PPPPPPPPPPPFFFFFFFFFFFFFFTTTTTTTTTTTTT

“I think I get it. You're shooting farts in my face on purpose.”

“Very good, see, you're not so silly after all? Here's a prize.”

“Yay, a prize!”

PPPPPPPPPPPPPPPPPPFFFFFFFFFTTTTTTTTTTTTTTT

COF COF

“So... My prize is one last session of swallowing your farts?”

“Nope. I'd love to give you another one, but right now, there's something else on the way.”

“My gift?”

“Yes, you're very close.”

“Mmmmmm... I know! More cake. You still have some left.”

“Very close, but no.”

“Okay, I give up, just tell me.”

“Okay, but first you have to open your mouth.”

“Ahhhh.”

“Perfect.”

Dylan lowers her ass further, leaving her anus almost touching Serena's mouth. Her posture is like a dog shitting, but much sexier as she arches her back. With an ass like that, it's instinctive to show it off.

“I used you as a filter for my farts before, my last gift will be to turn you into something even better. You're going to be my personal toilet. Get ready!”

In the short time it took Dylan to lift his ass to gain momentum and give a hard thump on the sheep's face, she stuck out her tongue, sticking it into Dylan's anus. With hours of experience swallowing poop, she learned that doing that would help the poop go down more easily.

“You already ate the chocolate cake I pooped for you, as my toilet, you will eat all my poop.”

FLOSH GURK STRECH

A giant log came out, kicking off this trip to the bathroom for the dog and the best gift Serena had ever received.

The poop hits with greater brutality, the log is 10 times thicker, heavier, and harder, and it comes out much faster, so much so that from start to finish, it only takes about 3 seconds. But that doesn't mean it was any shorter; on the contrary, it was 100 times longer than before.

And the next one wasn't long in coming; there's no rest for Serena.

“Aaaaahhhhhhh, I haven't pooped like this in a long time. You're going to eat a lot until I empty 
myself.”

Those words were not enough to give the girl the slightest idea of how much poop she was about to swallow at that moment. Each log followed without pause, pushing the previous one, stretching the mouth, throat, and stomach that were in its path.

So much poop made Serena's stomach grow visibly. This ability to compress waste inside their bodies that many furries have seemed to be failing with such an extreme amount.

The hours kept passing, until night fell, at which point Dylan simply lay down, using Serena's breasts as a pillow, and fell asleep right there.

But that was the end of her gift. Even asleep, his intestines continued to discharge, all night long, until morning, when the sun woke Dylan up. He stretched, but was still sitting there pooping.

*Yawn* “Aaaaahhhhhhwwwww, I slept so well. Good morning, Serena... I guess I can't greet you with a fart in your face today, haha. My anus is too busy feeding you.”

The girl, for her part, also had a good night's sleep. With her body being used to store so much poop, she was very tired, so when she closed her eyes, it didn't take her long to fall asleep.

And when she woke up, she could feel the impact of all the poop she had swallowed while they slept. The feeling of her stomach touching the ceiling was remarkable, it was so inflated.

“Hey, I feel like there's not much left, about 3 or 4 hours and you'll be done swallowing my poop... Although I feel like I'm forgetting something.”

After thinking about it for a while, he decided not to worry about it and made himself comfortable again to poop more comfortably.

Finally, at 9 a.m., for the first time in a long time, Dylan felt his intestines were completely empty. She noticed this too when she stopped receiving more logs down her throat.

“Well, birthday girl, that was your present. *Sigh of relief* Ugh, I'd been saving that for weeks for a special occasion, it feels so good to have unloaded it.”

Dylan got up, SLUSH a very wet and sticky noise was heard as he separated his anus from the living toilet.

He got out of bed, and with his ass wiggling happily like his tail, he left the room as if nothing had happened.

“I'm going to take a shower, when you're ready, come down to work.”

The girl remained in the room, lying down and devastated. Dylan had really destroyed this toilet. She couldn't move; she felt as if she had exercised all afternoon yesterday and now her body wasn't responding. And even if she could move, so much poop in her stomach would prevent her from getting out of bed because of its weight.

The last log was still in his mouth, with the end sticking out, since there was no one to push it in, and Dylan didn't push it in himself with a fart. This log, obviously, also got stuck in his throat, so Serna had to finish pushing it down, swallowing again and again.

GULP GULP GULP GULP GULP GULP GULP GULP

It's going down, but it will take several hours because of how big and thick it is.

After his shower and going down to the first floor, Dylan ran into a customer asking about his order. They had both forgotten to finish the donuts.
