Ok I had to repost this to make sure I get someone's name in here properly.
Sorry it took some weeks to finish, school and holidays are tricky, but both stories are done.
Special thanks to  MrRainbow for letting me use his pictures for both stories. Not only as thumbnails but also as sparks to this story.

Fight
Arminus walks from the Asylum Courtyard Bonfire to the double doors. “Before anything, I need to retrieve my souls before I lose them,” he says to himself. He triple checks his gear: estus flasks, miracles, armor, rings, and weapons. “That thing will drop above like always. I died somewhere in the middle, so I retrieve my souls and kill that dumb demon. Its hammer isn’t a problem thankfully, but those fat feet quake the ground stomping anything underneath.” He pauses briefly remembering those toes over him. “Hmghgm… Its belly is big and barbarous and can launch me with a hip check, depending if it doesn’t (gulps) “flop” on me. And I can’t attack from behind because now it knows how to use ihhh…. Iihht…. Iiihhtss….” He couldn’t control the stutter when speaking that single word. “Buuhh Butt,” the sleeper agent muscles in Arminus trembles terribly in terror when hearing that trigger word. Frozen for a few seconds, Arminus headbutts the door to break from his mental prison. “Ooouuch, ok ok ok (breathes) I can do this. With a personal pep talk he opens the doors and walks in.

Creeks from the door battle cry in the large, rugged hall, alerting the Asylum Demon to fight. Arminus looks up after opening the doors to see something huge in the middle of the same hall. The 40 ft smelly pear-shape, bottom heavy demon rests his hands on his hammer with the bell end on the ground. Arminus stands impromptu the demon’s figure. “What the hell is going on, you’re supposed to leap down not stand there.” While comprehending, the doors shut behind him, no going back now. He braces himself stable and investigates the room for his souls. “It was in the middle I know it or is it behind the demon’s tall, terrific tallness….…. Did I just think that?” The Asylum Demon curves its snarling face into a smile and lifts its hammer bell up to reveal the green illuminating light of Arminus’s souls. “What’s your plan here?” Do you even know what that is? Your jump entrance was probably the only intimidating thing you had.” Upset from the demon’s concealment, Arminus accuses it aloud, but with a worry in his tone. Earning him a low titter from the Asylum Demon.

It takes one step forward flopping its frame standing even closer to Arminus’s souls and resting its hammer bell down on the ground in its right hand. It points at Arminus first then points to his weapons. Arminus follows its finger to his talisman and mace and looks back to the demon. With a devious smile, it points down to the floor indicating to Arminus to drop his weapons. “Give me a reason why I should, you gigantic gross goon?” Arminus retorts. Unshaken by the insult, the demon steps backwards to raise two fingers. 1: it opens its palm towards Arminus’s souls on the floor. Arminus controls himself a little realizing the demon is offering his souls back. “But what’s catch in option two?” he asks.
2: the demon turns around, each step shaking its body mass in ripples, to show its backside. Making the demon’s already putrid smell worse. “Uuggghhhhnnn” Arminus covers his nose to prevent the smell. The demon veers its head over its left shoulder grinning and slaps its hip with its left hand. Creating larger ripples that shakes the demon’s huge hindquarters. Arminus’s brows raise viewing the spectacle of ass action in front of him. “That is…. astonishing….. uugghh I mean appalling,” he internally fights with himself closing his eyes and shaking his head to get a grip, but the Asylum Demon notices Arminus’s struggle over its body and this expands the demon’s interests.

The demon rotates its body forwards and stares down at Arminus with a stern face and points its fingers down again for him to drop his weapons. Arminus stands clueless of what to do. Thoughts race in his head. He craves to see the Asylum Demon improve by any means necessary, even if that means being subject to this demon’s, desires. However, he is also livid at the demon. After giving the demon 30 humanities on his own accord, the demon kills Arminus in a jeering distasteful butt crushing defeat. Arminus only wore rags with no weapons and no rings, making the fight, literally, heavy in the demon’s favor. Arminus closes his eyes, what choice should he do?

SUBMIT to the Asylum Demon so he can gain his souls but become vulnerable.
Or
FIGHT the Asylum Demon to gain his souls and show this thing who’s boss.

(Inhale) (exhale) Arminus lifts his talisman in front with his left hand and projects a miracle aloud, “Replenishment” for passive healing. “After what you pulled on me last life, forget it,” he answers. “Now I’ll give you one chance…” he waves his left hand to the side as if moving a curtain. “Move, so I can get my souls…” he lifts his two-foot mace with his right hand in front of him, “or I’ll make you.” His demand terminates any attempt for cooperation or compromise. The Asylum Demon frowns in angry disappointment at Arminus and carries the hammer with its right hand. Neither moves as the demon two hands its weapon and takes a wider stance bending its knees. “Unlike last time, I have my gear. So, you better enjoy that last win you walking gunk of garbage, because once I’m done with you…” He coats Sunlight Blade over his mace to intensify his magic and raw damage. “You’ll be a pile of disposal dust.”

Now completely engraging, the Asylum Demon throws the first strike, an overhead swing. Arminus dodges right, “That was quicker than usual.” The demon recovers too, and swings left which he dodges backwards. “Ughf, what the-” he turns around to see a pillar behind him. The demon bat swings right to left at his head. He rolls low and forward to dodge the bell that demolishes the use to be pillar behind him. After his roll, his nose rolls in from the demon’s stench. Without looking, he evades to the right CRRUUNCH an quivering quake shuffles him on the ground. He didn’t look as he scuttles an extra few feet in front of him and stands gird towards the demon. The demon stands lob sided due to its foot being stuck one foot into the ground. “Too close,” he states to himself breathing heavy. The Asylum Demon circles its head towards Arminus dead eyeing him as it rips its foot out of the ground CRCRHCHRHCRLLLEE. Armimus notices rubble falling off its foot, with some rocks crumbling between its tremendous toes. “(gulps) way too close.”

Now switching positions, Arminus is in the middle of the room and the demon faces him from the front door. The souls are closer to him but is in range of the demon to crush him. Arminus strategizes, “Its moves are quicker, I can’t even get a swing let alone grab my souls. Range is going to be my best friend in this fight. I’ll use the Sunlight Spear lightning bolt.” He jumps back conjures the Sunlight Spear in his right hand, but the more powerful the spear, the slower the attack. And this spear has the strongest attack. The demon notices his attack charging and leans back ready to lunge forward. After finishing the Sunlight Spear, he launches it at the demon. Who doesn’t dodge it but jumps over the miracle and towards Arminus with a hammer over its head. Stress surrounds Arminus along with the demon’s shadow and hammer, with little mind and all reflex he dodges under the hammer towards the demon again. With the jumping hammer slam, the aftershock on the ground left him belly flat on the ground, giving the demon the opening it needs.

The Asylum Demon lifts its left leg and as Arminus attempts to stand into crawling position, its foot comes dropping. “Mmnngrrhh, the hell?” the putrid paw presses on him with not only force, but with stench too. A tussle between Arminus and the filthy footfall. “No nnrrghh you don’t uuuggghh,” he pushes against the foot inch by inch slowly bringing him above crawling so he could stand. The demon perceives its foot not being heavy enough. But what about the entire leg? A savage smile appears on its face, as it casually careens over to its left leg. This presses Arminus down again from his hands to his elbows “Crap-” SPLAT. Two knees are dangling under the demon’s toes, while the rest of the body is under the demon’s left sole. A low spiteful snort is heard from the demon above, who feels the movements of an ant under its heal.

Lifting its foot, it sees an inch deep paw print on a pathetic prone person. “Is that (breathes) all you got?” Arminus challenges stubbornly but lamely. A surprising look displays on the demon’s face, its subject took a foot to the face and is still belittling it. Maybe it needs to step harder? The left foot falls again STOMP. That one shook the pebbles around the foot a bit. The knees stuck out from the toes and shook again too. Upset with this underwhelming result, the demon turns its heel into the ground on his head and shoulders SHUUFFTT SHOOFFTT SHUUFFTT SHHOOFFTT SSHHUUUFFTTT SSSHHHOOOFFTTT SSSHHHUUFFFTTTT SSSHHHOOOOFFFFTTTTTT. Every twist of its heel grows longer, heavier, and smellier on Arminus. Who unwillingly follows its pattern by his legs swinging with the demon’s foot twists. The Asylum Demon elevates its left foot to view the crude cadaver for a moment then steps on him profusely. STOMP (raises foot) STROMMPP (raises foot higher) SCRROMMCCHH (raises leg) SSCROONNCCCHHH (raises leg higher) SCCRRUUUUNNNCCCHHHH. Without looking, it raises its left leg high and back leaning all its weight to its right leg only to shift its weight to its left leg for one concluding CCCRRRUUUNNNCCCHHHHHH. Removing its foot, rubble sizing close to a person’s head shoots up from the ground due to the foots imprint. And Arminus lays face down in the pavement pit in the demon’s footprint. This display of dominance delights the demon and walks away from him to grab its hammer.

“Really is that it…” Halting in its tracks barely reaching its hammer, Arminus rises from his crater coffin to face the demon’s back. “Because I’m a little disappointed in the results,” he taunts while standing on his legs again. The Asylum Demon quickly rotates without its hammer in hand with a surprising yet angry attitude. Arminus assumes in his head, “Looks like that startled it, good because I am aching everywhere right now. Showing pain would give it courage to attack me. I got to keep this charade up until I can reach my souls behind it.” The green puddle of souls lies a couple feet behind the demon, who doesn’t recognize it yet. He continues to banter, “Surely that wasn’t your only move right? I mean after all with this talisman,” he shakes his left hand with a miracle cloth “I can heal myself passively in a fight.” He begins to walk forward towards the demon, who doesn’t move. “You did improve that much is certain, but you are still a downright disgusting dolt who can’t finish a little human like me.” The demon backs up while facing him still stale of showing emotion. This encourages Arminus to slander more, “You can’t grab someone with those dinky arms, even if you could your boorish belly would just get in the way.” The demon’s belly is right over the souls with its hammer on its front left side. It looks over at the hammer in desperation. A bartering idea occurs in his head. “Unlike you I want to fight, but I won’t fight someone unarmed. Because that just makes me an ungrateful degrading lost cause, like yourself.” The demon lowers its head and folds its hands over its torso in disgrace. “So let me grab my souls, then grab your weapon so we can finish this.”

Arminus notices the Asylum Demon hunches its head down and arms on its chest, assuming it is in utter sadness and embarrassment. With confidence he walks towards the demon, moreover to the souls to grab them. “That was easy.” He thinks as he bends down and suddenly WHAM a wall of filthy flesh invades his space and launches him upwards spiraling in the air. Not only did this disorientate him but it leaves him breathless too thinking, “What the hell just hit me?” While suspending in the air a bit, the demon positions itself under him with arms on its hips. “What’s it doing? Is it just going to watch me fall?” Arminus thinks as a grin grows on his face. “In that case I’ll just plunge attack it.” If the Asylum Demon gets hit by Arminus while he is falling, he will kill or extremely damage the demon. That is, if the demon stands still. A moment before his mace swings, the demon bucks its barreling belly up and out giving something for Arminus to fall on. Or in this case rebound from. The paunchy potbelly propels him into a pillar, cracking his back into it on impact. “Gaawwhh that hurt. It launched me with its torso into thi-” a shadow overhangs him as he stares forward at an olid obese object “…pillar.” He tilts his head back to see a ghastly grimace from the demon’s face. It stands inches away from him with the lower part of its terrifying torso slightly above him.

A small smirk comes from Arminus, “Heh heh, about what I sa-” FWOMP. The Asylum Demon slams its surfeiting stature into him with no remorse. Nothing but dangling hands and feet are seen from the outside. His small white angry face bares itself from the big belly’s beguile. The demon retorts with a grunt and another step forward CRANKLE. The pillar pleas in pain from the demon’s step, along with Arminus, but he doesn’t yell from it. Only a head remains as the greasy gut gobbles up his hands and feet. Or half a head with a pair of bitter brows beaming into its eyes. “If I scream it will know I am injured, but this is torture,” he mentally reminds himself in steadfast. The continuous detesting look from him at the demon agitates it to take another step ahead CCRRAANNCCKLEE. Its malodorous moldy mass envelops around the now splitting support structure. Short squirming from Arminus shuffles the demon’s stomach, giving it a sniggering satisfaction. This standstill strain goes on for 5 minutes until the demon stops feeling the squirming. It takes a couple steps back, while the sound of a wet rubber mat peels off the marble mast. And that white humanoid mat slides down the mast from his martyrdom in an exhausting sitting position. Content with his defeat, the Asylum Demon turns around. While circling, Arminus awakes from his afflictions, “(Inhales) that (inhales) sucked,” while catching his breath he views two monstrous mounds backing into him. “Shit” he avoids the broadside bash by falling to his right and rolling away SSSQUUAANNT.

He quickly spins to see the Asylum Demon “eat” the lower pilaster with its ass. The demon smiles unaware of it missing him. Jitters crawl over Arminus’s body as he views the terror of what could have been. The demon glances behind its right shoulder only to find its subject partly laying on the floor with fear in his features. It gives a scary smirk to him, with a gravid grunt it grips its glutes, CRRUUNNCH. The column crumbles behind like a Jenga tower, but with more pieces. With small debris and dust dribbling off its dangerous duff, Arminus remains still in fright. Paralyzing panic overtakes him, the pillar that once stood is gone, reduced to powder and pebbles. Standing in satisfaction of its display the demon ominously ambles towards him. “I could have died like that….lost in that things….things….” like a ray of hope, a small glimmering green puddle attracts him. From his position he can see under and somewhat behind the demon the souls he lost, a fire lights inside him. “Replenishment!” he shouts as he lifts himself and his left hand to activate his talisman’s passive healing again. 6 feet away from the human, the Asylum Demon stops pondering what he is doing.

“Even with that ass of yours, you can’t see your opponent behind it.” He states with determination refilling and replacing his dismay. “You need to work on your aim if you are gonna use that on me.” The maim in his muscles are miserable, but his healing is slowly taking care of it. He just needs to endure for a little bit. “My turn.” he brags as he conjures Emit Force. A white wispy miracle grows in his chest to a size of a beach ball. He casts the cannon miracle at the demon hitting the middle of its body. As the demon totters from the blow, he dashes forth with no hesitation and slides underneath the demon feet first. Unable to hold its balance the demon falls back with a resounding WHOOMMPPP. The demon’s gut grumbles grumpily from the miracle’s attack. Its body bobbles a bit from it then stops, except for its bum almost like it has a mind of its own. Well, it did, sort of, two white legs jerk underneath its left cheek.

A cruel cackle come from the Asylum Demon with energetic euphoria empowering its prevailing placement. It roughly repositions its rear side-to-side on top of Arminus KKIIRRMMPPTT KKUURRMMPPTT KKIIRRMMPPTT KKUURRMMPPTT KKIIRRMMPPTT KKUURRMMPPTT. Arminus’s view is nothing but darkness with the terror of toches tossing him like a Cesar salad. With the passive healing of Replenishment, he is still alive, but that doesn’t mean the torment is any better. After 7 minutes, the demon stops torturing him and slightly leans forward to follow-up on its fatality. Arminus is now face-up in the split of the demon’s suffocating seat showing his head and shoulders. His body is frail, leaving any chance of escape futile. “Please…” a pathetic pant comes from him attracting the demon to veer over its right shoulder. “Let me (inhales) get my souls (inhales) I’ll do (inhales) anything.” A mute moment moves over the room as the demon debates this dilemma GGRRMMBBBLLEE. A guttural answer arrives arousing the Asylum Demon, but alarming Arminus. It gives a fat (HUMPFT) and flutters a flagitious PPPUURRRRBBBBTTTT into his face. Ferocious fetal fumes force their way on his face. “Ohhh God (cough cough) you loss cause of lousy lard (cough) you are a disgusting downright (cough cough) dumbass who-“ MMMMRRRRROOOOORRRGGGNNNN. He freezes in fear from what he hears in the demon’s flank and sees on the demon’s foul smile. It leans back, “Nooo-mmmmmhhhmhmm” and hushes Arminus beneath its heavy hindquarters and heaves. FFFRRRRROOOOMPMPMPPPMPMPMPMPMP. Now that same gruesome gas invades his smell, and he doesn’t even have a nose.

A soothing sigh exhales from the Asylum Demon glaring at its ass to relish the screaming and struggling from its straining subject. Ideas spark in its head of how to lacerate its lacky. It begins to twist its tremoring tush clockwise then counter clockwise MMEERRFFTT MMAARRFFTT MMEERRFFTT MMAARRFFTT MMEERRFFTT MMAARRFFTT. Following up with weaving him under its whopping wagon from squishing him from right cheek to left cheek RRUUMMFFKK RREEMMFFKK RRUUMMFFKK RREEMMFFKK RRUUMMFFKK RREEMMFFKK. While switching between the twists and weaves, the demon also adds a couple of bulky butt bounces and ghastly gas gusts here and there too BWONG BWONG FFAAARRPPPTT BOING BOING BOING PPPAARRFFFFFF FWOMNG FWOMNG FWOMNG FWOMNG PPPUUURRRRFFFFSSSSSS.

This powerful posterior punishment goes on for 15 minutes leaving Arminus completely helpless. The Asylum Demon ceases its scrutinizing sequence to check its captees condition. There is a small fumble under its flank along with caustic crying expelling from his mouth. How this sap is still alive surprises and stews the demon. Any new moves it uses on him don’t work, but one move might work. A sinister sneer grows on its face as it stands up. Arminus lays limp face down and breathing heavy unable to speak. He lifts his head up to see the only thing that matters, his souls. His cripple body is four feet away as he crawls towards his souls. The demon jumps and begins to flap his wings. Arminus hears this and sees the demon’s shadow become smaller. Even hurt he hurries closer to his souls. He races to grab his souls before he loses them forever. 3 feet away and the demon flaps slower “Come on…” he pleads to himself. 2 feet away and the flapping stops “Almost there…” 1 foot away and its fat ferocious flank furrows as it falls “Pleeaassee!” WWWHHHAAAAAMMMMMMMMMMMMM an earthquake shakes the entire hall with a column or three falling over and breaking. The demon’s signature move hits its mark. The atomically atrocious ass ASSault expands like playdough landing on the floor creating a 5-foot-deep abyss. A fog of broken floor fragments covers the ground a foot high. It views its vandalism in the room but directs its focus at its flank. The dust clears and his hand extends from its fissure, inches away from the 200,000 souls. He moves it forward pathetically now an inch away from the souls. With a serious squeeze, the demon heaves its huge heavy haunches upright to deliver a final hefty hoopla to Arminus. PPPPPPPPPPRPRPRRRPIIIIIIIRIRRRRRRAAAAAAAAAAAAATTTTTTTTTSTTSSSSSSSSSS

That blast blew every part of Arminus into ashes that mix in with the remaining dust of the hall. The green light puddle of souls vanishes and all that remains the Asylum Demon, winning its victory against a snarky overconfident moron. Pleased with its work, it stands up FFWWWIIIIPPP ripping its rotund rear end out of its rupture. It flies up to its regular waiting area and knowing how stubborn Arminus is, waits for him again. Time and time again Arminus is stuck with this same boss unable to defeat it. A combination of belly, feet, butt, and gas attacks keeps him under the demon in the most painful way possible. At the cost of 30 humanites, two lives, 200,000 souls, and an endless loop of destructive defeats. It was not worth it for him, but in the end, he did upgrade this boss.
