"Come on, baby..." Tello gasped. He was working his fist further and further into the infant's ass. "Gosh, you're freaking bottomless!"

Momi continued to pee himself as Tello fisted him, sniffling as he emptied himself onto the tanuki. His chest was coated in piss and he huffed as his hand got more and more dirty, spreading the mess around as he vigorously pumped his fist in and out of the baby bunny's fat butthole. He certainly didn't seem to mind being stretched out (he had been doing it all day, after all), but surely there had to be some sort of limit? When would he get tired and go the heck to sleep?

But that was how it was when you had a baby. You had to make sure they were properly fisted, fucked, and emptied every day. It was pretty tiring, and Tello could very well stop at any time, but... This baby was just so warm and cute... And his smile as he continuously peed all over Tello's belly made him hard as a rock. He continued breaking his asshole, using his other hand to edge himself until finally he couldn't take it anymore.

“Uh... Momi... I'm gonna fuck you, okay? It might be even harder than this fisting, so…”

Momi shrugged and spread his legs wider. He didn't care, as long as something was in his ass.

Tello pulled his dirty fist out, struggling not to drool at his gaping fuckhole. He had forgotten just how stretchy babies could be, and seeing Momi proudly display his shitty leaking ass made him eager to see just how wide it could be stretched. He grabbed the bunny's plump legs and pushed his cock in without a second thought.

He moaned as he slid into the messy hole, his dick easily swallowed up to the balls by the warm living toilet. It was already fairly lubed up with baby fluids, but Tello filled him up with pee again just to make sure before going wild. Momi cried our a bit as he was brutally plowed by his owner's fat rod. His poor butt was already sore from the fisting, and Tello's sloppy tanuki dick was on another level.

“Hush, baby.” It was Tello's turn to smile. “I know how much you love having things in your dirty shithole. You can be cute and mess yourself all day, but you love being filled just as much as you love being emptied.”

Each thrust earned Tello adorable little gasps and cries from the bunny, as well as spurts of piss every now and then. His entire body was milking the tanuki's shitty cock, and it didn't take too long for Momi to be filled with loads of fresh nut. Tello continued fucking him, riding out his orgasm for as long as he could until eventually he stopped, panting and gasping.

“Jeez... That was short…” Tello grimaced. “I'm not done yet, though.”

Momi grumbled as he was pulled off of the dick, but soon found the nasty thing being shoved in his face. He eagerly took it in his mouth, cleaning his own mess off of it and swallowing it all like a good baby should. Tello struggled not to moan as Momi's tongue ran up and down the length of his cock, eventually moving up to swirl it around in his cruddy foreskin. He was receiving the best cock cleaning he'd ever had from a baby...

Momi continued suckling on the massive thing until he had cleaned all the shit and cum off of it, and was rewarded with a bellyful of piss to top it all off. Tello humped into his mouth lightly, making him choke a bit as his mouth just wasn't wide enough for a proper facefuck, but he made do with nursing on his slick cockhead and foreskin and taking as much as he could in.

“B-baby... I'm not gonna last much longer, haha…” Tello looked a bit dazed. “Is there enough room in your belly for more tanuki cum?”

Of course there was! What a silly question to ask. A baby's belly was meant to be filled with cum. Momi sucked as hard as he could manage, eager to have more to eat from this wonderful cock. Tello eventually gave in, moaning a bit pathetically as he came hard in little Momi's mouth, pissing load after load for the baby to swallow. It lasted about a minute this time, and Momi's belly bulged slightly from just how much he had eaten.

“D-damn...!” Tello panted as he pulled away. “I outta whore you out. I could make some nice cash with a sleeve as good as you.”

Momi giggled. He felt a bit sleepy from all that eating and excitement, but he wasn’t completely satisfied yet. He couldn't go to sleep with his ass feeling so empty! He reached down and spread his hole wide for Tello, cum and piss still leaking out of it onto the bed.

“Hmm, impatient, aren't we? I'm gonna take a little break first, and then I'll see about cleaning you up.” Deep down, he knew little Momi would definitely want another round of fucking before bed, but he really needed a bit of a break, at least to drink some water so he could pee some more.

Momi grumbled again as Tello left to go get some water and something to eat. He had already had plenty to eat himself; he just wanted to be filled up from his other end again. And now he had to wait! He started playing with himself as best as he could, fisting his gaping hole and sniffing and licking off any mess he got on his hands. Tello's cum sure did taste good…

-

The break wasn't too long thankfully, and soon Tello was back for more. He laughed as he saw Momi casually playing with his fuckhole. “I hope you saved some for me, Momi. I'm still a bit hungry myself.”

Momi responded by lifting his legs up and spreading his ass open again.

“Hehe, what a good boy…” He knelt down and quickly started making out with the abused baby hole, lapping up the last of his own cum and piss and shoving his nose and tongue as far in as he could. The smell of a dirty baby butthole was one of his most favorite things, but it quickly started to get bit boring since Momi had done such a good job of cleaning himself out. He sucked on his fat wet ballsack for a bit before chiding him. “Hmm, didn't I tell you earlier to use my face as your diaper?” He demanded. “Go on, empty yourself all over me.”

Momi didn't really have to go right now, but he did love using faces as diapers. He tried extra hard and managed to piss all over his owner's face, blushing as Tello guzzled down the warm baby juice. “Mmph... That's more like it.”

He continued digging around in Momi's warm ass, sniffing deeply and eating any mess he could find. When it seemed mostly clean, he decided to start fisting it again to force out anything that was waiting for release. “This is how you really fist a baby, Momi.” He said as he pushed his arm in. “Your tiny baby hands can't reach that far inside. You've gotta have a friend to help you!”

Momi moaned softly as Tello groped around inside of him, eagerly trying to spread himself as wide as he could. He loved having big fists pumping in and out of him, and his poor ass quickly gave in and let loose all over Tello's fist.

“That's much better…” He grinned. He started going deeper and faster, stretching the bunny out more and more, sometimes stopping to make him clean his own mess off of Tello's hand with his tongue. Momi sure did enjoy being Tello's glove, and showed his appreciation by pissing uncontrollably all over him as his body was rocked to and fro.

“You're the dirtiest baby I've ever played with. I should give you a bath later on…” He stood up and let Momi pee all over his cock before pushing it in again. The baby's ass was so wide that he now fit almost perfectly inside, with room to spare, and it was even warmer than before thanks to the fresh baby mess.

“Now listen here. I'm gonna fuck you really hard again, and after that you'd better go to sleep, okay? This is the fourth time today, and it’s starting to get a bit late.”

Momi nodded. He didn't really have any intention of sleeping, he just wanted to be railed again.

“Good. You babies sure are high maintenance…” He started thrusting, fucking Momi's mess back into his aching butt. “I promised to ruin your ass though, and that's what I'm gonna do.”

Tello plunged all 8 inches of his fat tanuki prick into Momi's and slapped away at his tiny baby ass. Nothing wrapped around his junk better than a baby's broken hole, and he was determined to last longer than a few minutes this time. Momi as Tello pounded him mercilessly, feeling him stab underneath his stomach over and over again. It was hard to shit since he kept having it fucked back into him, and the force of it making him pee all over himself again. Tello went at it almost angrily, chuckling at the sight of his toy wetting himself over being fucked so hard. “Guess I won't have to give you a bath after all.”

He kept rawing Momi's fuckhole, thrusting as hard as he could manage, making the cute baby drool as he was properly used again. For a while, there was nothing but the sound of fat tanuki balls slapping against little baby butt, Momi whimpering and Tello grunting with each thrust. Tello eventually slammed in hard as he came for the fifth time that day, filling Momi with as much seed as he could manage. He pulled out in the middle of his orgasm and forced his dirty cock into Momi's mouth, making him gurgle and choke as he lightly fucked more cum and shit into his facehole. Tello groaned as his high died down a bit, and he slumped forward onto the bed, forcing almost his entire dick down Momi's tight baby throat. “Phew…!”

Momi was barely able to breathe with the giant rod in his mouth, but thankfully Tello didn't sit there for too long. He sat up and emptied his bladder into Momi's face again before pulling out. He almost always needed to pee after cumming, and his dick felt pretty sore now. “That was a bunch of fun, huh?”

Momi coughed a bit, struggling to swallow everything and keep it down. He stretched himself out and spread his legs a bit more. His puffy ass was leaking all over everything… How wasteful! He looked pretty tired too. Getting dicked and messing yourself nonstop all day was a bit exhausting.

“I guess it's time for a diaper.” Tello said. He went to the closet and dug around a bit before pulling out a nice cute one. “If you're still hungry, you can eat your diaper mess in the morning. I know how much you love doing that.”

Momi sighed and rubbed his belly. He was full for now, but that always sounded nice. There would certainly be lots to eat after today.

“Should I wear one too? We could take turns sniffing each other's diapers…” He pondered for a bit and then shrugged. “I'll take care of you first. And the bed, as well…”

He cleaned up and was soon snuggled into bed with a diapered-up Momi, who was already mostly asleep. He smooched the bunny's wet nose and closed his eyes, thinking about all the fun they'd have tomorrow. Taking care of a baby was a lot of work, but it was always worth it when you got to cuddle them to sleep at the end of the day. 

“Sweet dreams, baby Momi.”
