After the incidents in the previous day, Renato was sound asleep on his leaf bed in his hut. When he woke up, he took notice that his improvised diaper was wet. Thankfully, he didn't soak the leaf bed... He sat up and stretched, then started to think about the events prior. He felt quite ashamed about having listened to his lower urges while interacting with Marcus, but that opened a venue for challenge: maybe Renato could improve his self-control by trying to go the whole day without pooping. That would probably not be possible, since he needed his daily bowel movement, but he could try to go as long as he could. He disposed of his diaper, exposing his uncut erection, then walked to the river nearby, washing himself and quickly losing his erection once the smell of urine was no longer on his fur to tempt him. Once done, he tied a new diaper on himself and walked towards Marcus' house.
	Once there, he entered, finding Marcus asleep on his bed, wearing just a diaper and a long pink shirt to protect him from the cold. Marcus' feathers didn't protect him from the cold as well as Renato's thick mammalian fur. Renato sat down and awaited until Marcus was awake. Renato didn't a morning pee, since he wet himself that morning. Soon enough, Marcus began to wake up. He sat up with a squish. Renato's ears perked up at the sound and his nose picked the smell of urine coming from Marcus' diaper. Renato's penis began to stiffen. Marcus lewdly groped his diaper, pleasuring his penis. Then, he looked around and saw Renato sitting near his bed. Marcus smiled and reached to pet Renato with the wing he was using to grope his penis through the wet diaper. The smell of urine on Marcus' wing was felt closer to Renato's face, further arousing him, but Renato had honed himself through years of sexual deprivation. He had not masturbated in two months and wanted to remain "clean".
	- Morning - said Marcus.
	- May your morning be most pleasant - said Renato.
	- You could just say "morning" back - said Marcus, amidst giggling.
	- Apologies.
	Marcus lied down on the bed again, causing his diaper to squish. Renato glanced at Marcus' soaked diaper for one second, before averting his eyes.
	- You are so formal - said Marcus.
	- I have to be - said Renato, as politely as before.
	- What brings you to my house, Renato?
	- I was thinking about yesterday and I feel like you could help me, not only with my reading level, but also with my self-control.
	- Renato, you should chill out... - said Marcus, now with his voice with a little more concern. - You will break yourself if you continue depriving yourself of pleasure.
	- I need to be the best leader possible. I insist.
	Marcus sighed dramatically.
	- Fine - he said. - What should I do for you?
	- I need to suppress my defecation, ideally, until tomorrow - said Renato.
	- No can do! - said Marcus, shaking his head. - You are going to hurt yourself.
	- I reckon you did feel some pleasure yourself last time.
	- Yes - said Marcus, blushing. -, but it was not right. I was in a moment of weakness!
	- It is not like me to employ seduction to get what I want - said Renato, getting up and rubbing his paws on his belly. -, but nature is calling right now. Whether you help me or not, I'm not going. You have the chance of making things worse and more arousing for yourself.
	Renato pushed on his belly with one paw, causing a loud gurgle to soar. Marcus' penis stiffened and his breath became more labored.
	- You play dirty! - complained the cockatrice.
	Renato slapped his belly with the other paw, before grabbing a chunk of fat and shaking it, making the belly jiggle and give out a growl saturated with slow, shallow vibratto (effect command 445, if you are on Protracker).
	- Okay, I'm sold - said Marcus, fully aroused, pressing a wing on his diaper and humping it discreetly.
	- Good - said the skunk. - I need to keep an eye on me and not let me relieve myself, even if I need it urgently.
	- But what if you hurt yourself?
	Renato thought.
	- I won't hold it for the entire day, then - he said. - If I can hold it until lunch, I'll be satisfied.
	- Good... - said Marcus, relieved. - But it will be easy.
	- Not if we make things intense. I know you and your dad dabble with substances and edibles. You probably are aware of plants and fruits that work as laxative.
	Marcus thought with all blood available to his brain during the erectile crisis going on between his legs.
	- We can use the fart berries, a suppository and an enema for good measure - he said.
	Renato began to undo his diaper and he lied on the ground, for Marcus hut had no concrete floor, belly face-down. Marcus went to the other room, coming back with a hose, a funnel and a jar of brown, thick liquid. Renato's penis was hard the whole time and was starting to tingle fiercely. The skunk could not help, but wonder if there was a component of lust in what he was doing...
	One end of hose was stuck inside the skunk's rectum and the other end, attached to the funnel. The liquid began to be poured in. Of course, not the whole jar went in, only one third of it. Renato's stools were usually mushy due to being well-hydrated, so the enema was redundant, from a medical point of view. The goal was not to treat constipation, but to torture the skunk. Once the enema was in, Renato clenched up tightly. Marcus grabbed the suppository and stuck it into Renato's rectum.
	- Now, the berries - said Marcus.
	Renato tied his diaper back. The pressure in his belly was high, but he put on his best mean face of respectful determination and rawdogged through the discomfort. The duo leaves the hut and goes into the forest... They find the bushes where the fart berries grow. A fart berry is a succulent, very sweet, very fibery, very juicy fruit, that is as big as one's head. They picked four. And that would be Renato's breakfast. Eating a bit of one is bound to make a person gassy, but eating a whole of such berries can turn them into a great laxative, due to the combination of liquid and fiber. Each fart berry counts as 36 prunes, in terms of fiber. Eating four is like eating a dozen dozens of prunes. Renato stuffed himself with the four fart berries, all while valiantly holding his morning poop and his enema. His belly was roaring loudly... and both cubs had very powerful erections. Marcus didn't even change his diaper, so excited he was to see that scene unfold before him. He knew it was risky, but his lust kept him from stopping Renato.
	As the day goes on, the berries get digested and the suppository is dissolved, things began to go more difficult for little Renato. While tending to his daily tasks, he sometimes felt his bowels cramp strongly and he would have to bend over, put his paws on his butt and tuck his tail between his legs. Not only he was full of very mushy poop, an enema and now also runny poop, he also was filling up with gas. His belly was becoming round, taut and even slightly reddish under the fur. In only thirty minutes, he thought about quitting, so big was the pain, but he thought he could tank through it. And, indeed, after another thirty minutes, he thought he got the hang of it. But the berries were not yet fully digested and, by the second hour of the challenge, his bowels were filling up even more, with his stools fighting for room those packed bowels with the gas bubbles that made loud noises whenever they burst.
	And all of that was affecting Marcus, who was tagging along. He could not change from his diaper into his loincloth, or his erection would becoe even more obvious. Whenever Renato squirmed and groaned, Marcus would feel his hormones peak so hard that he would get dizzy. His diaper was drenching in precum. Renato was doing what he could and it was clear that he would be unable to hold the entire day as he wanted. He would be dying by the lunch break, when he would be able to rest from tending to the garden and from watching the frontiers of the village. Marcus nearly passed out hearing the ever growing noises coming from Renato's taut, distended, rigid belly.
	- Renato, I'm sorry, but I feel like I'm about to cream myself... - says Marcus, as the lunch time approached.
	- I'm glad you are liking it... - said Renato, who was now sweating cold. - There is one more thing I want you to do.
	- What would be it?
	They stopped walking when they were in the middle of a trail between the garden and the huts.
	- I want you to try to make me have a messing accident - says Renato.
	- Renny... - said Marcus, as worried as he was aroused.
	- Trust me. I want this. Please, do your worst.
	Renato forced himself to stand straight, allowed his tail to flag up and thrust his swollen, sloshing belly forward. Marcus could almost see the vibrations running on the overwhelmed tummy...
	- I'll do my worst, then... - says Marcus, salivating, approaching his wings to Renato's belly.
	Knowing that there's risk of soiling, and badly, Renato's boner returned. Marcus pushes his wings on Renato's belly, making it growl. The skunk grits his teeth, squeezes his eyes shut and immediately places his tail between his legs again. He squeezes his legs together and stands on tiptoes, but arches his back, thrusting the belly further against the molesting wings. Marcus begins to squeeze alternately, left, right, left, right, making the bowels move and try to force the poop through Renato's exhausted sphincter. Not only, the gas bubbles are still multiplying in his bowels. His colon felt packed and with no more room in it. Renato was still doing his best and still had a good amount of control, but sometimes he felt his sphincter tremble, open a little and then be quickly clenched back shut. His eyes widened and he realised the gravity of the situation. His mouth opened to breath more, panting. But he was not giving up. Marcus would squeeze violently to make the bowels move, then massage softly to ease and relax the barriers that Renato had set up, but Renato was an iron wall.
	- Lift your tail - says Marcus.
	Reluctantly, Renato allowed his tail to flag up again. Marcus undid Renato's diaper, knowing that he would be in danger by doing that. He parted Renato's cheeks, exposing the tightly cleched anus and began to tickle it. Renato wiggles and tries to contain the tide, but the tickling is making his other muscles contract and push on the bowels. He was pushing against his will. He giggled, snorted, whimpered, chuckled, squirmed, twisted about, while his belly growled hard. It felt heavy, like an anvil.
	Their penises were so hard that they could well pierce through stone. Marcus was old enough to ejaculate and he was leaking a lot of precum. Renato, however, had no such ability and his orgasms were still dry. His penis was tingling powerfully, so were his nuts and his prostate, that was being squeezed by the stools. To make matters worse, he had to pee again and the bladder was stimulating his prostate as well. Marcus wished he could fuck Renato, even in that state, but that would be too much. Renato would hate Marcus for that. Yet, Marcus had the honor of groping the village's leader buttocks and anus...
	Finally, Marcus had the effect he wanted. Poop came out as if a bottle of ketchup full of shit had just been squeezed. It made Marcus' wing dirty. Renato kept trying to hold the rest back. Marcus had enough. He stood up behind Renato, stuck a feather inside Renato's anus, fingered him hard and fast, while his free wing went to Renato's belly and squeezed it with full force. Renato groaned loudly and shit began to come out pouring, ruining Marcus' wing, landing on the ground under them. Marcus inserted another finger, taking advantage of the rectum's "lubed" state. Crap kept flowing out erratically as Renato's defenses crumbled during the fisting. Renato was on the verge of dry orgasm and Marcus was panting behind Renato, so very willing to stick his penis into Renato instead of his wing... Suddenly, Renato cried:
	- Enough! I can't hold it anymore!
	His sphincter could no longer close. Marcus pulled his now very stained wing from Renato's ass. The skunk fell to his knees and got on all fours, shitting a massive amount for five minutes, that came out in fifteen waves, releasing his morning poop, the fresh poop made by the berries, loud and powerful farts and the enema. Marcus had an spontaneous, hands-free orgasm, breeding his diaper so hard that, if it could get pregnant, it would. Renato, on the other hand, managed to suppress his orgasm, but not his urine. He peed on the ground, making a puddle under himself. After he was done, he was relieved, but much of the shit had landed on his feet. Both he and Marcus could use a bath in the river...
	- Wow... - said Marcus, upon realizing that Renato was done.
	- Yeah... - said Renato. - This was the hardest challenge yet...
	- What now?
	Renato got up, his ass hurting and burning like a million suns. He rubbed his belly, loving the feeling of relief. His genitals were still tense and his prostate still felt overchaged, but Renato dutifully ignored the impulse to masturbate.
	- We take a bath - said the skunk. - then we meet at the mess hut for the lunch. You may want to change your diaper into the regular loincloth.
	Marcus nodded. He could hardly believe that Renato could bounce back to his formal, polished self after such a humiliating display of swinish behavior. Renato noticed that a lot of crap had falled on his diaper... He tied it on himself, causing a turd to press on his erection and another on his butt crack. He tensed up and had a defeating accidental orgasm. He stood there, feeling the contractions in his crotch, before picking himself up again and walking towards the river. Marcus followed right behind...
