Chapter Text
“N-Nissy?” Pentious whimpered, peeking over the pillow he was hugging to his chest.
Arackniss grunted.
“Are you…” he swallowed, “o-okay? Are you still okay?”
Another grunt, one that evolved to a deep breath. “Yeah. ‘M still good, for now at least.”
“How will I know when you, er, well, turn?”
Arackniss chuckled, his voice noticeably huskier and breathier. “You’ll know, don’t worry. But if it scares ya that much, you don’t gotta be here, I’ve rode out heats before.”
Pentious scoffed, his confidence returning for a brilliant moment. “Well, consider myself morbidly curious. As your captor for the evening I at least intend to see what beast I have tamed. I’ll see myself out should you become too unbearable.”
“Good, good,” Arackniss said, flexing against the ropes, “that’s good. Do that if I start saying some fuckshit. Just don’t let me out no-matter what.”
“I know, I know.”
“Even if I’m beggin’ an’ cryin’, Pent, you cannot let me out.”
“You have my word, I won’t.”
“Good.”
Silence fell. Arackniss’ hair swooped over his eyes and his hands became still, limply hanging around the pillar which Pentious had tied him to. The steady ticking of the grandfather clock was the only thing that brought Pentious some level of comfort, but he couldn’t shake the feeling of helplessness that crept up his tail. He felt like he was a lone, old fisherman, and Arackniss was some ancient horror from the depths coming to swallow him whole. He took as quiet of a breath as he could to steady himself. Arackniss couldn’t get out of his ropes; two-hundred-plus years of practice had served him faithfully many a time before this one.
He wanted to talk to Arackniss, but he didn’t want to shatter the calm before the storm. Maybe Arackniss needed the quiet to focus and deny these absurd sexual fantasies? Maybe. Pentious didn’t feel any better with that thought, but he clung to it regardless. A part of him was disappointed that he was so nervous.
It was thirty, nearly forty minutes later—Pentious couldn’t do anything but count the seconds—when Arackniss took a sharp breath and pulled his head up to rest against the pillar, his mop of hair still hanging over his eyes.
Arackniss’ lips twitched as he inhaled gulps of thin air. “P-Pent?”
Pentious could feel a phantom droplet of sweat trickle down his face. “Y-yes, Arackniss? Do you want to talk about anything? Perhaps how you’re feeling?”
Arackniss nodded a few times. “Burns.”
“It burns?” Pentious asked, leaning forward in worry.
“Yeah. It burns.” Arackniss struggled out, writhing gently against the ropes wound across his chest. “Feels good.”
“It feels good?”
“Feels too good,” Arackniss smothered a moan, but couldn’t stop himself from squeaking out a needy whine, causing a fiery blush to spread across his face, “everything feels too good.”
“Are you okay? Do you want to call this whole thing off—”
“No!” Arackniss snapped. “Don’t ask me that again, Pent. F-fuck…”
Seeing his lover so needy both appealed to Pentious’ deepest fears and his most inappropriate desires. He needed to be strong.
“Listen to me, Nissy. You’re doing fine so far. Tell me what it feels like.”
“It’s, it’s just…” Arackniss grunted, tugging at his bonds, “I’m fuckin’... swimming, Pent, I feel like I’m floating. Can barely think, can barely breathe—everything feels so tight on me, Pent, like I’m bein’ squished. But in, h-hah , like a good way. I like it, Pent, I can’t not like it. All tingly, ‘m all tense. Fuck, Pent, I dunno what I’m sayin’, y-you should go before I start askin’ stuff of ya.”
“You’re not too far gone yet. We’re in this together, Niss, thick and thin. I can handle some naughty words, I’m not a child.”
Arackniss bit back another moan as he tugged on the ropes, causing them to dig into his fur. “It’s like being so close to, an, a-a—ah—a fuckin’ orgasm, and it hurts so bad. I just wanna, fuckin’… r-ride, you, Pent, I need to… fuck, Pent, you gotta go. I’m losin’ it. I’m barely holdin’ back on ya. It’s never been this bad before.”
“What?!”
“It’s you , Pent, I ain’t done this with you here before… I-I just, I can’t take it, I’m gonna—I want you, I want you so bad it fuckin’ hurts, and you’re so close, a-and I just need a touch—just gimme a fuckin’ touch, and I’ll be okay, please! I’ll clam up, please, Pent! Please , and that’ll be it, I swear!”
Pentious would laugh if he weren’t so scared. And aroused. This was so unlike Arackniss. All of his level-headed charm and gruffness had evaporated in mere moments. Tears gathered in the corners of Arackniss’ eyes. Pentious sucked in a small breath and slithered over to Arackniss, kneeling down to come to eye level with the blushing demon.
“Let’s do it like this: I’ll give you one touch, and you can use it whenever but—”
“Now!” Arackniss spat. “Now now now, Pent, I’m burning up—”
“But,” Pentious interrupted, “I’ll only give you the one, so if you decide you want one later, I’ll refuse. You still want it now?”
Arackniss nodded, his chest rising and falling with nervous anticipation. Pentious rolled his eyes, and hesitantly raised his hand as if Arackniss was going to cleanly sever it. With a small puff of air, Pentious cupped Arackniss’ cheek with his hand, gently thumbing under his eyes. Arackniss’ eyes slid shut and his mouth hung open, a torrent of satisfied groans tumbled from his mouth as he leaned into the touch. His adorable cooing trailed off when Pentious pulled away.
“Hey! What the hell gives?!”
“I gave you your one touch. No more.”
“Don’t fuckin’ play wit’ me, Pent, I ain’t—” Arackniss seemed to catch himself, and forced in another breath, slowing his breathing, “—okay, okay. Fine. No more.”
“No more, that’s right. Who’s a good boy, huh?” Pentious teased, rising to full height. “Who’s a good little doggie?”
A conflicted look boiled behind the blush on Arackniss’ face, one that he tried to shake off. “I ain’t a dog, you asshole.”
“So sorry, dear, but with what I just saw, I’m inclined to believe otherwise.”
“F-fuck off.”
Pentious barked out a laugh and returned to his spot on the couch, his hands shivering. Arackniss was warm, and more so than usual given his coat of fur. Just what was happening to his beloved? He’d have to study this process sometime in the future.
Arackniss had stopped talking, but Pentious could hear his laboured breathing from across the room. He quietly breathed in through his nose and out through his mouth, his shoulders rising and falling slightly with every inhale and exhale. His hands seemed mostly dormant, save for sporadic bursts of energy when they would tug at the ropes, seemingly not of Arackniss’ own volition.
“Noodle…” Arackniss muttered, his nickname sounding tired and strained.
“Yes, dear?”
Arackniss turned toward Pentious, the fur on his face matted with sweat. “I miscalculated. I can’t… fight it for much longer… I just… wanted to say sorry. I-in advance.”
Pentious scoffed. “Nissy, please, we’ve been over this. I can handle a little profanity. Why, I fight your brother on a weekly basis, you know. I’ve heard it all, even if I don’t understand any of it.”
“Y-yeah, yeah, it’s just,” Arackniss let out a shaky breath, fists clenching, “I get really, well, ‘into it.’”
“Pfft, what could you possibly do to me when you’re all tied up?”
Arackniss groaned, arching his back against the pillar. When he opened his eyes, the sincerity was gone, replaced by something more vibrant, something hungry. “Oh, I’m more into the things you can do t’ me , Penny~”
Pentious chuckled nervously, and tugged on the collar of his coat. Arackniss’ voice had taken on a thick, lusty tone, one that pulsed in both of his ears at once. Was it hot in here, or was he just going crazy?
Arackniss grunted, shaking his head violently. “F-fuck, Pent! I’m about t’lose it. Promise me you’ll keep me tied up! Promise me!”
“I promise, I promise!”
“F-fuck, Pent…” Arackniss’ head fell forward. “I f-feel it comin’… I’m just, so… fuckin’… warm.”
A meaty snap cracked through the air, and Pentious shot up in surprise. Nothing seemed out of place, and for several tense moments nothing was, but by the time Pentious noticed the incongruence in Arackniss’ legs, it was too late.
A lurid moan burst from Arackniss’ mouth as his body began shifting. His legs lengthened and bent at uncomfortable angles, his arms twisted and grew longer, and his body—his chest specifically—bubbled and spasmed with demonic magic, all soundtracked to the hideous snapping of bone and the stretching of flesh and muscle. If Pentious didn’t know better, he’d be convinced that Arackniss was being ripped apart in front of him. By the time the snapping stopped, Pentious couldn’t breathe, his squeamish nature getting the better of him. Arackniss had grown at least several feet taller, even as he was sitting on the floor. His legs protruded like stilts from his body, bent backwards at the knee like an animal, and when once his arms had comfortably wrapped around the pillar he was fastened to, they now jutted upwards from the extra room the transformation has afforded them. His hair seemed to be smoother, puffier in a way, and the fluff on his chest now pushed uncomfortably against his suit, bulging out against the ropes caging him.
In shock, a terrible revelation dawned on Pentious. Other than his colour palette, Arackniss now looked almost exactly like his brother.
God help him if he was even half as lustful.
A relieved groan spilled from Arackniss’ mouth. “Much better.”
That voice, that lurid, inescapable voice . It was so far from Arackniss’ normal growl. Pentious hated it, yet wanted to hear more of it.
“N-Nissy? Dear?” He squeaked out, trying to keep an even tone. “Are you feeling… alright?”
“I’d much rather be findin’ out how you feel, Penny dearest,” Arackniss drawled, writhing against his restraints in an uncharacteristically inappropriate way, “when was the last time I got to feel ya up, Pent?”
Pentious brain took several seconds longer than usual to fire off a response, something that he could tell eight predatory eyes were privy to. “Well… the last time we, er, ‘did anything’, was about fourteen days ago—”
“Two weeks!” Arackniss said, the pain in his voice somewhere between genuine and played-up. “Two whole weeks since we last bumped uglies. You must be wanting, Pent~”
A retaliatory thought died on Pentious’ tongue. He came to his senses. “Nice try, Niss. You told me to refuse you any further gratification, and I fully intend to do so. You’re not getting untied.” He crossed his arms and raised his chin at his boyfriend, not expecting the hateful glare that shot through him when he looked at him again.
“C’mon, Penny, think about what you’re givin’ up here,” Arackniss cooed, pulling on his ropes again, “don’t you remember how good you make me feel when we fuck?”
Pentious swallowed. Maybe it was the demonic magic getting to him, but he could remember all the times when they had gotten lost in the moment, when their kisses and touches were nothing more than tokens of their passion and their love for one another.
Arackniss chuckled mischievously. “I can see your thoughts, Pent, I can almost feel your dick throbbing from here. I know you wanna just pin me down an’ go to town on me. So why not?”
“N-no!” Pentious said, his resolve faltering. “You made me promise… t-to not untie you, regardless of how… utterly… ravishing , you look…” Pentious shook his head and growled, forcing himself to sit as far away from Arackniss as he could.
“Oh Penny~” Arackniss sing-songed. “You can’t get away from me that easy~ You’re gonna fuck me tonight, Pent, and you know it.”
“Rrgh, get out of my head!”
“Only if you let me get on top of ya instead~”
Pentious would cringe if the idea weren’t becoming more and more appealing to him. Maybe leaving Arackniss alone would be beneficial towards his captivity… Pentious did say that he would if he couldn’t handle Arackniss’ overbearing flirting. But should he escape, Pentious would be alone in his manor with a sex-crazed demon prowling around…
He sighed. He was too old for this. “You’re despicable, you know that?”
“I’m delightful and you know it, Penny. Why haven’t ya let me out yet? I thought you promised me ya would.”
Another response died on Pentious’ tongue as a playful grin spread on Arackniss’ face. “Nice try, Nissy. I promised no such thing. I’m not untying you.”
“Ugh! Why are ya such a fuckin’ buzzkill , old man?”
“Hey now, no need to be rude!” Pentious said, Cherri’s trademark insult ringing in his ears. “Besides, if you even want me to think about setting you free, you’d better start worshipping the ground I walk upon.”
“Believe me, Penny, the first thing I wanna do is be on my knees in front of ya. But how am I supposed t’worship ya if I’m all tied up, hm? Checkmate, bitch.”
“Ugh, you take after your brother in all the worst ways when you’re like this.” Pentious waved his hand flippantly at Arackniss and retrieved his hellphone from his coat pocket.
“My brother ain’t got shit on me, and y’know why?”
“Hm, why?” Pentious asked, idly flicking through his phone.
“‘Cuz he ain’t got what you give me, Penny~” Arackniss said, moaning slightly. “He don’t got a man who can make him scream~”
Pentious shivered, and felt his sheath stiffen. He was dangerously close to his erections popping out, something that would only give Arackniss more ammunition to tease him with. He was supposed to watch him, not encourage his perverse fantasies.
“And guess what?”
Pentious swallowed, and closed his hellphone, sitting up to stave off his impending eruption. “What?” He said curtly.
Arackniss leaned toward Pentious as much as he could. “He don’t got a man who can give it to him whenever he wants~”
Another shiver, one that drew out a breathy gasp from Pentious.
“Whatsa matter there, Penny? Got somethin’ t’share with the rest of the class?”
“We’re n-not in an educational curriculum, Niss.”
“What if we were, and I was in one of those sexy schoolgirl dresses? Would ya bend me over a desk and ‘help me with my homework’?”
“I am not nor was I ever a legally qualified tutor, Niss.”
“But what if I needed to pass this class, hm?”
“Niss, do I have to gag you to keep you quiet?!”
“I mean, you’ve already got me all tied up~”
Pentious groaned again, and clenched his fists in frustration. What he would give to pacify the voracious demon before him. Perhaps a better question for him to ask would be what could he do that wasn’t… well, that? He was Sir Pentious, the smartest demon in the entire Pentagram! Surely he could find a solution that wasn’t as primitive as simply telling Arackniss “yes”.
But he was starting to really want to let Arackniss go, if not for his unquenchable scientific curiosity than for what could possibly be the most vigorous intercourse of his entire existence. Every one of his muscles was beginning to sizzle with sexual excitement, his crotch now outlined with a noticeable bulge. The idea was tempting, more than he would ever admit, but Arackniss had told him to be strong, and Pentious was nothing if not the mightiest of them all. He took comfort in that fact.
“Nissy, you’re not thinking straight. I’m—”
“—oh I agree. I’m thinkin’ pretty fuckin’ gay right about now—”
“—I’m doing this,” Pentious interrupted, blushing, “for your own good. Who knows what you’ll do if I let you out. You could hurt yourself.”
Arackniss chuckled. “Please, Penny, you ain’t that big.”
“I DIDN’T MEAN IT LIKE THAT!” Pentious shouted, not bothering to hide the colour in the eyes on his tail.
“Look, Pent. I know what I want, and I want it very, very badly,” Arackniss said, shrugging casually, “and it just so happens that the one thing I want is also keeping me from getting it. So, I’ll be forced to take some ‘drastic measures’ if ya don’t let me out, and let me start ridin’ you like a fuckin’ stallion. Last chance.”
Pentious almost laughed. Hadn’t he told Arackniss in the past that he wasn’t an equestrian? “Like you’re in any position to negotiate with me, Nissy. You’ll only regret it if I let you out and one of us ends up hurt. Imagine how you’ll feel come morning.”
Arackniss went still. Pentious shoulders tensed up, and the faint sound of rope fraying and breaking filled the empty space between captor and captor. Pentious’ eyes widened to dinner plates.
“Ya see, Penny dearest,” Arackniss started, the taut ropes around his fluffy chest falling away, “ya probably shouldn’t poke fun at the slut with a knife.”
“You’re… not… a slut.” Pentious murmured, his voice cracking with fear.
Arackniss threw the ropes off and stood to full height, towering over Pentious by at least a foot. He revealed the tool of his escape, his trusted balisong knife, and flicked it closed before dropping it into his pocket. With seemingly practiced motions he fluffed his chest and fixed his hair to peak attractiveness before locking eyes with Pentious.
Pentious swallowed audibly, and tugged at his collar before laughing awkwardly. He had never been so terrified or so aroused. He didn’t realize how good Arackniss looked with his brother’s height, and the way his chest fluff made the buttons of his coat strain teased Pentious more than it had any right to.
“N-no hard feelings, r-right?”
Arackniss laughed, and cracked his knuckles. He tilted his head to the side and looked up as if he was in deep thought, before shrugging. “One.”
“A-and what would that be?” Pentious squeaked out.
Arackniss smiled, his pupils narrowing. “Two.”
