You never know who you're going to end up friends with at school. But I think me and Asriel, the actual prince of the underground, are pretty tight. We first met when I called him a "stub-horned little faggot who wishes he could take my giant dick like his mom" and he's been a great friend by giving me his lunch money and letting me work out my stress with some nice kitty punches. So naturally he invited me over for dinner one night. Well, he actually invited this cute deer girl, but I shat her out after lunch, and invited myself in her place.

I showed up right at 5 on the dot looking awesome as usual, brushing back an ear with one paw. They were a little surprised see me, since they said to get here at 6, but it'd be rude to be late. Strolling in I found Asriel playing a game while Ms. Dreemurr was making dinner still. Also Undyne was there? I didn't know she was coming. Couldn't match Asriel's mom's fat goat ass, but I wouldn't mind plowing some fish buns too. Asriel was focused on the game, but still managed a friendly, if a little concerned "Howdy!" He didn't plan for me to be coming, but at least we had company. For some reason I have a hunch he wanted to call them witnesses. As Asriel was close to beating a particularly tough boss, I ran over, booty bashing him out of the way.

"Scoot over, it's my turn!" I grabbed the controller and performed a totally epic finisher on the boss, leaning back smugly. "Yeah, now that's how it's done!" Having proven my awesome, I turned the console off and stood up to go check on Tori. "Hey Ms. Dreemurr." I casually called as I walked over to the kitchen, my teacher looking down with a soft sigh. "Hello Nico, how are you doing this evening?" Her tone was tense and a bit slowed, as if she didn't want me there with every fiber of her being. No idea why, I was a model student. Even brought her an apple one time. Sure I'd rubbed it all over my sweaty sack, but that was just flavoring. Sluts love a nice salty seasoning!

"So, what we havin'?" I asked as I leaned closer, giving that legendary royal rump a little bop with my hand. Toriel looked as uncomfortable and grumpy as usual around me, and took a step to the side. "The quality of snails have been dropping lately, so I thought we'd settle for hotdogs." The icey glare that followed quite well said that she would not accept any of my expected jokes. That only made me want to do it more, but I was fucking hungry and decided to focus on food first. "Cool, I'm gonna just go grab a snack!" Toriel slightly sighed with relief. "Very well, but don't spoil your appetite too much, my child." That was probably the nicest thing she'd said to me in a while. She never seemed to approve of my relationship with Asriel, no idea why. I even let him lick my sneakers clean sometimes. Maybe it was that time I trapped him in his locker overnight after taking a shit in it... he really didn't like that much.

Returning to the living room, I headed over to the royal guard captain. "Heya Undyne!" I called out with a wave. She was pretty cool, not as cool as me and she lacked the cute factor that made me irresistable, but I totally got why the armless little retard looked up to her so much. Her response was a little better than Tori's, but only just. I guess she had caught me shoplifting and pissing on walls a few times. "Oh, Nico? I didn't know you were gonna be here!" Walking over I looked up at her with a big grin. "Of course, we're having hotdogs you know!"I sagely told her, as if it would be a huge revelation. But I was seriously hungry. Despite being a cat, I actually wasn't big on seafood; kinda hated it in fact. Fortunately fish GIRLS were quite different. And I did need a little warmup for dinner. So I quickly gave Undyne's ass a smack, not even trying to disguise it, before scowling. Pretty firm, good bounce, solid 7/10 on my scale. In other words total garbage barely worthy to lick my shitty asshole. "To bad you ain't getting my hotdog. But don't worry, I'll let you take a free tour as an apology!"

I sneered with a big taunting grin as I grabbed gave Undyne a gut punch. Obviously the captain of the guard was not gonna go down from a punch for a random school kid, but it distracted her for just an instant, enough time for me to turn, pull down my pants, and present my bare gray ass, unloading a nice big fart from that dumb deer.

BBBBBBBBBBBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF!!!!!!

As the smoggy gas blasted Undyne, she fell back as a twitching mess, going into spasms from the sheer stink polluting her system, beads of foamy drool running down her lips as I smiled, giving my ass two firm mocking pats before pulling up my pants. "Yeah, some captain of the guard. My dick cheese is ten times stronger than you. Yeah, that fart'll probably kill you in about ten minutes, I'll try to digest you before that. Like I said, you ain't worth fucking." Asriel starred on in horror, wanting to stop this but the smell was too intense, even from their relatively safe distance, Asriel and Toriel were both completely off balance from the nose raping miasma filling the house. Before their eyes, I grabbed Undyne with both hands and opened wide, shoving her head right into my mouth.

SLLUUURRRRRRRRRRRPPPPP!!!

With a wet swallow I gulped her down halfway, her still twitching legs hanging limply from my maw, I was quite glad she didn't piss herself, some of the girls I gas do that. Fucking gross. She wasn't nearly fishy in the way you might fear, closer to chicken I'd say, but I always found meat comparisons dumb anyway. I was never one to savor a meal, and swallowed her fast, not just because Asriel and Ms. Dreemurr would be regaining their full cognitive functions soon By the time they did, my belly was bulging and I was sitting back, patting it with a huge 

BBBBBBBBBBBBBBBLLLLLLLLLLLLLLLLLLLLLLLLLLLLRRRRRRRRRRRRRRRPPPPPPPPPPP!!!!!!

My belch shook the room as they looked on in horror. Asriel covering his nose as he squeeked out. "You.... you ate Ms. Undyne! Nico, how could you?!" Lightly burping out an eyepatch and flicking it aside, I rolled my two eyes. "Uhh, I ate one of our classmates today? Is this seriously new or unexpected to you? Geez; you know I'd been calling you faggot and MK retard, but maybe I should swap your nicknames, cuz' I think you might actually be braindead." Asriel scowled at this, looking angrier than I'd ever seen him before, I might have struck a nerve there, or maybe just said something he wished he had the guts to say. 

But my banter with Azzy would have to wait as my stomach gave a loud gurgle. "Woah, raincheck on all this. That fish is bursting the dam!" I said, little puffing farts squeeking out of my pants as I rush to the bathroom, pulling them down and flopping on it with a relieved sigh. Immediately a catastrphic stink flooded the house.

SSSSSPPPPPPLLLLLLLLRRRRRRRRRRCCCCCCHHHHHHH!

A wet sloppy sound came as I squeezed out a fat twenty inch log of shit, my tailhole pinching it as I leaned back with a sigh of deep relief. "Oh yeah, that's more like it. You would'a been a lousy fuck, but god you were a great shit!" I said as I patted my gut again, loud farts shaking the bowl as more turds exited, falling in a sloppy pile, nearly filling the bowl entirely!

PPPPPRRRRRRRRRRRRRRRAAAAAAAAPPPPPPPP!

As the last fart rang out, I stood and pulled up my pants, no wiping for this cat, pulling the handle on the toilet. Naturally it immediately clogged, just the tiniest bits of the first turd too much for the toilet, and the whole thing was simply a death sentance. Brown water ran over the top as I strutted back out, the toxic stink erupting as I opened the door. "Hey Azzy, mind plunging that thing, your house after all, and you can't ask your mom to do something like that. 'sides, we'll be busy." I tosses Asriel the plunger with one hand, and he stared in absolute horror at what lay beyond the bathroom door, lip quievering as his eyes gazed into infinity and despaired.

Asriel didn't want to do it, but after seeing me eat the actual captain of the fucking royal guard, he didn't want to fight. That just left me and the MILF goat. Walking over to Toriel, I stared up at her. "Sooooo, you find a boy who can total a bathroom insanely hot, don't you?" She was one step away from killing me at this point. "No. No I do not you..." but before the flames could come out, I sat down in the kitchen chair, unzipped my pants, and let it hang free.

The flames vanished, and Toriel stared in complete shock, almost the same look as Asriel but that expression was not horror or fear. She was in awe, not just of the scale of the kitty cock before her, but it's sheer unfettered reek. The apple had been horrifying, even from the garbage it had stunk up the classroom, but this was on another level. Sweat, musk, and so much bubbling cheesy smegma. The mere sight and smell of my unwashed cock destroyed her restraint or inhibitions, and though her mind cried out to stop, she could not, she plunged to her knees and took my shaft in both hands, kneading it greedily. "Gee, goat ass is a pedowhore, who would'a guessed."

Toriel hated what she heard and hated what she was doing, but could not stop her body. Instincts and impulses beyond her understanding where at work, and she greedily rubbed my sac, rubbing her face all over it, slathering kisses and licks along my heaving nuts and sweaty shaft, noticeable lipstick marks quickly forming across my package. "Now this is what we should be learning in class, don't 'ya think?" Toriel could only let out a slight moan as she worshiped my balls. "God, why am I not getting straight A's already?" I muttered, my grades weren't that good despite always copying off Asriel's homework... maybe the fact that his mom was the teacher had to do with it.

"Glad you like my cock so much... now lick my asshole." Toriel was horrified, trying to resist as I lifted my legs a bit more, knees in the air to allow her to see my full taint and asshole. She tried to pull away but couldn't disobey. The musk and stink enveloped her mind further. "I said lick it!" I ordered as I released a horrible but slightly more restrained fart. Toriel choking on the toxic gas flooding her lungs, feeling like she needed to vomit but unable to do so. My farts weren't ALWAYS fatal, although long term exposure could cause horrible side effects and lung problems. But what bitch lasted long enough to worry about that? So basically this toot was less "game over" and more "congrats, you now have the lungs of someone who smoked ten packs a day for 30 years".

But Tori couldn't stop, sniffing deep of my hole before tentatively placing her tongue on it, tears streaming down her face as she regretfully licked the still warm shit from my crack. Slurping it down into that greedy bitchmuzzle. "That's right, I'm having hotdogs, your dinner is all over my shitring!" I grabbed one of the freshly finished hotdogs and added some ketchup, Chicago can suck my cock, before munching on it as Toriel obediently licked my ass. I blew out several farts as I stuffed myself with hotdogs, Toriel forced to inhale each, her tears running hotter until they actually steamed from the foul muggy air emerging from my preteen asshole!

BBBRRRPPPPPPT!! FFFFFRRRRRRRRRRPPPPP!!!! BBBBBBRRRRRRRFFFFFF!! PPPPFFFFFFFRRRRRRRR!!!

Finally I finished off the last of the hotdogs and stood up, cock slapping Toriel to the floor. "Alright, raise that fat boss butt." I ordered, Toriel scowling but unable to disobey, still not understanding this effect I had on her. If it was some perverse magic or something deep inside her I had forcibly awakened. As Toriel obediently lifted her behind, I grabbed her hips and pulled up, mounting her from behind. "Pussy or ass... hmmmm, Ass, don't want any more lameass little goats in the world, right?" Toriel looked back with a scowl, but dropped it as I gave her ass a hard spank, sending it jiggling. "Yeah, now that's a butt. About fucking time." I said with a snotty laugh before pulling up and letting my tip tease her tender virgin pucker.

"This your first time? Well too bad, I don't hold back. Get ready for the rollercoaster, fuckdump!" I shouted as I slammed my hips in, Toriel's entire body rocking and her eyes frankly bugging out as my colossal meatslab tenderized her asshole, sending a huge bulge through her body as I pushed in, gripping her cheeks hard. As soon a I was all the way in, I gave her ass a hard spank. "I'm the teacher now, and today I'm showing how to rearrange your guts!" I taunted as I pulled back slightly and thrust in again, each one prompting shrieks and moans from Toriel. My sweat and smegma smearing over her inner walls and serving as a form of sickening lubrication.

The house shuddered and shook, and even as he futilely attempted to clean the utterly destroyed toilet, Asriel finally couldn't ignore it any longer. Tossing the plunger aside he left the wrecked bathroom and walked to the kitchen. "Mom, what's the ma...." This family seems to be prone to hundred yard stares, cuz' that was the third one today. Asriel looking on in complete disbelief as he saw me fucking his mother's asshole into the kitchen floor. "N...Nico you can't be..."

But I quickly shot him a stare. "Shut up spermstain, can't you see we're busy?" As he stared on in total disbelief I continued pounding Toriel, each time the bulge went further, each time she shook harder, moaning in total disgust and ecstacy. Feeling my filthy cock polluting her ass, and my shit still caking her mouth. She felt exactly like the meat toilet I had reduced her to. Asriel slowly spoke again. "You have to stop this Nico!" Which led to a soft sigh.

"Oh fine, I'll wrap up if that makes you feel better." I was planning on dragging this out, but I was a guest here and did seem to be getting on Azzy's nerves a little. So I decided to be quick. I humped Toriel two more times, before pulling back on her cheeks, squeezing to ensure she was in up to the hilt and then let go. Moaning in total release as a gargantuan cumload erupted, filling Toriel utterly, her belly flooding with my cum and growing larger and larger. Asriel stared in surprise and confusion... and then horror. 

SSSSSSSSSSSSSSPPPPPPPPPPPPPPPPPPLLLLLLLLLLLLLLRRRRRRRRRTTTTTTTTTTTTTT!!!!!!

A sickening wet rip sound came, and cum exploded over the room. The bits of fur, horns, and clothing fell to the now cum oblitered kitchen floor as I shook off my cock, drying it on a less soaked portion of Toriel's dress before pulling up my pants. As Asriel stared on, tears running down his eyes, I gave him a soft pat on the shoulder before heading for the door. "Thanks for dinner but, see you tomorrow. Wonder who our new teacher's gonna be, I'm pretty excited." And with that I left, having had a nice fun evening. Leaving Asriel to an empty house full of a stinking pool of cum and smegma, and a toilet clogged to the brim with several feet of shit.
