A Lesson In Mating

Summary:

When Perpetua unexpectedly enters your lives, you and Copia long to give him the security he's been denied his entire life, all the love he deserves. But preparing him to find a mate of his own may prove to be the greatest challenge of all...

Notes:

This is my contribution to lycanthra's CREATURE PERPETUA MONTH 2026 on tumblr, and hoo-eee is that a lot of fun to write. Creature Perpetua, Vampire Perpetua, Werewolf Perpetua....all fucking FIRE.
We're only one week in and already the fics have been delicious!

(See the end of the work for more notes.)

Work Text:

When your husband suggested such an unorthodox demonstration, you truly thought he was joking. You might not have agreed to it so enthusiastically if you'd known how serious he was. But the way Copia's face lit up with surprise and affection for you when you said 'yes' told you that there was no way you could back out now. Not when it was your near-constant loving but vocal nagging in the early days before Perpetua's arrival that was part of why they'd ended up so close in the first place.
Copia had been understandably bitter about being replaced by his brother and reduced to office work. And every video clip of his twin parading across the stage with such effortless swagger and confidence, the audience pulsing with excitement and hanging on his every word and movement, made him bristle with envy. 'MY audience,' you'd hear him mutter before roughly turning off the ancient monitor on his desk and slumping back into his chair. But you'd assured him that it was all for the good of the Ghost project, the benefit of the entire Ministry, that his brother's successes were ultimately his successes too. Endlessly patient even when he was at his most petulant, you waited by his side as the months dragged on and the time when they would finally meet face to face drew nearer. And to your surprise, by the time that day came, Copia actually seemed excited to finally bury the hatchet and embrace the unfamiliar comfort of family he'd never know before. But he found out rather abruptly that there was more to that family than meets the eye.
Nothing could have prepared you for the reality of Perpetua without his stage glamour, though you'd have thought your more trusted Ghouls would have at least tried to warn you. Copia had been mentally rehearsing their meeting for weeks. A nervous hand shake that would dissolve into a tight, teary hug, and before they knew it, it would be like they had never been apart. And yet here they were, face to face at last...well, not exactly face to face. Copia's face was twisted in a confused expression, Perpetua's big wet eyes peering up at him from where he was crouched, visibly trembling, flanked by a pair of Ghouls who held a tight grip on the leash that fastened to a collar around his long, angular neck.
A tense silence hung between them before Copia finally cleared his throat and spoke, a bit more formally than he intended in his nervousness. "Welcome, Perpetua...I mean...V...I mean...Um...F-Fratello."
But the unsettling creature before him only blinked and cocked his head to one side.
"He don't talk, y'know," huffed one of the road-weary Ghouls.
"Does not...talk?," Copia asked quietly.
"Nope," snapped the other Ghoul, shoving the leash into Copia's gloved hand. "And he's your problem now."
And just like that the escorts were gone, vanishing in a puff of brimstone and sulfur.
Copia gulped, turning to you with a lost expression. "What...What do we do with him?"
You shrugged with a bemused chuckled. "Take him to the vet and get him checked out?"
He scowled. "That is not funny, amore."
"Who's joking? Look at him." Perpetua had one of his legs in the air, scratching awkwardly at a spot behind his pointed ear. "Pretty sure he's got fleas."
.
In the hours that followed, a bit of prodding and a lot of bribery finally elicited some answers from a few of the more cooperative Ghouls. Apparently they were under strict orders from the Upper Clergy that the precious resources required to keep the new Papa in his human form was only to be used for the brief time that he was onstage and not a second more. And furthermore, once they returned to the Ministry, their supervision of him was no longer needed as their energies would be better used elsewhere.
So basically, he was on his own, or really...they were.
There was definitely a learning curve in the early months of their newfound brotherhood. Less of a reunion and more like adopting a feral animal. And Sister Imperator was conveniently absent once he'd arrived, so you and Copia couldn't even get an explanation from her as to why his twin was such a creature, assuming she would have chosen to be forthcoming with such information, or that anything she'd say could be trusted.
So you both did your best to care for Perpetua, making it up as you went along. And Copia was right about one thing...they rarely spent another moment apart from that point forward. Wherever he went, his brother was close on his heels, tail wagging excitedly, and to your surprise and delight, Copia didn't seem to mind. If anything it was a welcome distraction from the mundane duties of his position as Frater. And over time Perpetua did seem to absorb mannerisms and behaviors from his twin, becoming a bit tamer, not that Copia could ever have been called a model example of a human being.
And even though the creature remained non-verbal, they seemed to have no difficulty communicating. Despite their conversations appearing on the surface to be one-sided, Copia prattling on and on about rats or video games and Perpetua grunting, growling, and chittering in response, they understood each other perfectly.
You'd done your fair share of bonding with the new addition to your family as well, doting on him like a mother hen. And Perpetua ate up your attention and affection eagerly, having never had such a nurturing figure in his life before. He snuggled up to you any time you'd let him, purring and wriggling happily as you scratched at his wiry fur and toyed playfully with his soft curls, stroking the spines of his wings that were especially sensitive until he shivered from your loving touch.
In a lot of ways it felt like your little family was finally complete, but something, call it women's intuition, told you there was still something missing. You saw the wistful look in his big black eyes when he watched you and your husband in even the most innocuous of tender moments together. You observed the longing glances he gave the pretty Sisters who crossed his path. And on the lucky occasion one of the dared to approach him, to offer him treats or give him tentative head pats, he was over the moon, pinging off the walls and dangling from the rafters until you'd have to secure the help of the Ghouls to get him down.
In spite of how contented he was in his new life, you knew he wanted what you and Copia had. He was lonely.
.
"He seems quite happy to me, mi amore," Copia whispered, gesturing to where his brother was curled up at the foot of the bed, claws twitching slightly with the thrill of whatever he was chasing in his dreams.
"I'm not saying he's not happy with us," you continued. "But there are things that he needs that we can't give him. Think how much happier he could be with a mate."
He considered the thought with a slight scowl. It wasn't a subject he enjoyed discussing, the idea of his best friend's attention being drawn elsewhere bittersweet if he was being honest.
As usual, you could read his mind. "I know you love him and I know you have decades of lost time to make up for. What your mother did to you, what this entire Ministry did to both of you isn't right or fair, and it's not your fault. You don't have to atone for their cruelty." You saw his breath catch and his fists clench in an effort to control his emotions. "But we do owe it to him to try to make sure he has as much of a normal life as we can."
"You are right, of course. But the Sorellas...They are afraid of him," he muttered, massaging the back of his neck as he always did when he was attempting critical thinking. "How are we going to convince some poor young thing to let him paw at them. Even you, amore, have to use the spray bottle on him at least once a week."
"Well maybe it's time to do some more concentrated training." You dug a notebook out of your bedside table, ever the notetaker and maker of lists. "I can work with him on how to be a little civilized on a date. Sit in a chair, eat with silverware, use a napkin, that sort of thing. Maybe you can help with the more gentlemanly things...like holding a door open for a lady and not scooting his butt across the carpet. And we really do need to try again to get him used to wearing pants. Having your junk out too soon on a date is just bad manners."
Copia nodded emphatically as you scribbled, his spirits visibly lifted. Having a plan was a relief, a lifting of a weight off his shoulders he hadn't realized he'd been carrying. "This is a very good plan. Mia bellissima bambina has such a lovely big brain."
He leaned in a kissed the spot under your ear that made you squirm. "And just think, love," you mused aloud as he let his lips trail down the pillar of your neck. "With his focus elsewhere, we might get a little privacy once in a while."
"My thoughts exactly, bella donna..." He was just nudging the strap of your nightgown down the slope of your shoulder to bury his face in your decolletage when Perpetua's head popped up, blinking eyes glowing red in the dark.
The hunt and sexy time...were over for now.
.
In spite of Perpetua's feral nature, he proved to be a quick study. And you were careful to reassure him that you loved him just the way he was, but if he was able to make a more genteel first impression, one of the pretty Sisters he'd been pining for might actually give him the time of day and adore him just as much as you and his brother did. But hopefully...with sex.
After a while he was walking upright in public, making the rounds in the Ministry dining hall, resting his head in the laps of friendly Sisters, batting long lashes at them and flashing a sharp-toothed smile in hopes of getting some flirtatious praise and maybe even a morsel from their plate. And it worked like a charm. The girls he fancied were more often than not, sufficiently smitten. Beast or not, the little guy was a charmer.
Before long his social calendar was overflowing with encounters, carefully curated of course. Movie nights with spooky horror flicks to make them cling to him for protection and he'd bare his fangs at any monster who dared to scare his companion. Romantic picnics in areas of Primo's garden where you were fairly sure there would be no small animals darting through that he'd be tempted to take off after.
You and Copia really had to congratulate yourselves on doing such a good job making him into such a catch. But pretty universally, like clockwork, after a few weeks the budding romance would end abruptly and without any explanation that you knew of. He never had a shortage of appealing girls waiting to be next in line, but his morale was getting noticeably lower each time and you knew it was your duty to figure out what kept going wrong.
You did a bit of snooping, coaxing information from the more gossipy Sisters, hoping to figure out why every attempt at a bonded relationship seemed to end when it did. It didn't take long to get answers, and it was really no surprise, the words 'slobber' and 'teeth marks' and the phrase 'to shreds' coming up more than a few times. The overwhelming critique seemed to be that as soon as things got remotely physical, he became unmanageable and downright terrifying.
You knew he had a vague knowledge of carnal activities, having walked in on you and your husband on more than one amorous occasion, understanding boundaries not being one of his strong suits. But even though you had virtually no knowledge of his life before coming to the Ministry, you had a terrible suspicion his experience when it came to human coitus was nonexistent.
When you relayed all your reconnaissance to Copia he was as heartbroken as you were. Was Perpetua really doomed to be solitary forever? Something had to be done...
.
"Ah...AH!...Fucking hell..."
"Feel okay, amore?"
"His tongue...It's so...So...So long and HOT..." Copia did his best to hold you steady, arms wrapped around you where you reclined in his lap and leaning back against his chest, but Perpetua's tongue was relentless, strong and thick, slick and forked, snaking along your walls and hitting your g-spot with such ease and pressure that was it as unfamiliar and unsettling as it was pushing your body towards climax at a break-neck speed.
"Remember you are supposed to be telling him what to do-"
"I know...I...I...FUCK..." You'd been quick to instruct Perpetua early on to be more careful with his razor sharp teeth pricking at your sensitive flesh, but once his tongue was inside you the words came like molasses. "Oh my God!!" Your body went rigid, legs shaking violently within the tight grip of his talons. He lapped up your sweet release with a low, rumbling growl, bulging eyes blown wide and the vibrations combined with the continued flicking of his tongue inside you kept the waves coming, not ebbing but feeling like they were only getting stronger.
Copia could tell you'd reached your limit, tears streaming down your cheeks as you thrashed in his arms. "Enough, V. Enough!" He tugged roughly on the long curls between his brother's horns and the creature pulled away, reluctant but apologetic, leaving you strangely empty and trembling. He shuffled back a few paces on the bed to watch you with a cocked head and nervously furrowed whiskered brow, clearly worried he'd done some sort of harm to you.
Copia left you for a moment, hurrying to get you some water, and left to fend for yourself you'd clamped your legs shut and curled up into a fetal position, sobbing quietly from the overstimulation. Perpetua inched towards you until he was close enough to nudge your shoulder with his snout and give a questioning whine.
Your eyes fluttered open and you reached for him, stroking the ruff of thick fur along the curve of his spine and letting him nuzzle into your breasts. "It's okay, Pet. You did so well. Really well. I think you might be a natural."
His tail thumped happily against the mattress and his purrs rippled through the soft flesh of your bosom.
"Here, amore." Copia pressed a glass of cold water into your free hand and helped you to sit up even as Perpetua stayed glued to you. "Perhaps we should call it a night, eh? I know this is taking quite a bit out of you-"
"Absolutely not," you said sternly. "We agreed that this is the only way he's going to learn. We committed to this and we need to finish what we started."
"Okie dokie, you are the boss. Have you, eh, sufficiently recovered?"
You took another big swig from your glass before handing it back to him. "I'm ready. Let's do this. Pet, go back to your spot, honey."
He leapt obediently from your side and returned to the armchair in the corner where he perched and awaited his next instructions, wings nervously fluttering and eyes blinking fast. "Now, V, we will do just as we did before," Copia explained. "I will demonstrate and then you will get a chance to attempt what you have learned. Okay?"
Perpetua nodded and grunted in assent. "And remember what I said before...Mi amore and I have been together for many years and knowing each other's bodies and preferences does not happen overnight. Becoming a good lover requires a gentle touch, careful observance, and a lot of patience."
Copia guided you with experienced hands to get on all fours, leaning down to whisper in your ear. "I think this position would be appropriate for him to master first, no?" You agreed and posed yourself, spreading your knees wide. He lined the head of his aching, neglected cock up with your slit, muttering to you under his breath. "So nice and wet, amore. How nice of mia fratello to get you so ready for me." He redirected his attention back to the lesson at hand, addressing Perpetua who was wiggling with barely contained excitement in the corner, cocooned tightly in his wings. "Now, you must go slowly. It is better to enter her more slowly than she wants, in which case she can tell you to go harder or faster, than to go too fast which might hurt her."
He slid into you with all the exaggerated control he could muster, through your slippery walls until your hips met and you let out a shaky gasp. "Alright, amore?," he asked, stroking your haunches with gloved hands.
You nodded, reaching back to give his wrist a reassuring squeeze. "I'm fine, just sensitive." The intensity of the orgasm Perpetua had pulled from you still left you a little rattled. "You're going to have to keep this short and sweet, love. I'm not going to last long and I won't be able to control it..."
He gave you a quick pat on the rump before continuing. "And in this position, you can let your hands roam over her body. Explore her thoroughly, and see what makes her react positively." He leaned forward, cupping your breasts and kneading them until you moaned and pulsed back into him. Without stopping he pulled out slowly and pushed into you again even deeper, almost painfully slowly but hard enough to make your toes curl and a shiver run through you. "Fuck's sake, Cardi," you hissed. "Wrap it up, I can't take much more."
His calm was maddening as he continued to instruct his brother while you came apart at the seams. He snaked his arms around you before straightening up, pulling you flush against his chest but holding you still. "See how beautifully she stretches around me...So soft and tight..."
The new position was more than you could take, the angle hitting your g-spot too perfectly. "Please...Please, Cardi...," you whimpered pitifully, wriggling in his firm embrace in search of relief and letting your head fall back into the muscular crook of his neck. "Please let me cum..."
"You know I would love to, amore, but it is V's turn now." He gave you a tender kiss to your sweat-beaded temple before easing you carefully off his familiar girth and setting you back onto your original position. "Come, fratello. And be very careful with your claws, per favore. Mio tesoro...She is a strong but she is also delicate."
He slunk towards you slowly, as if he didn't really trust himself with something so precious, the complete trust with which you offered yourself to him. He rested his paws gently around your waist, long fingers almost able to circle you completely. You felt his swollen, leaky tip press against your entrance and you braced yourself for the onslaught to come. You'd caught enough glimpses of his intimidating size, both flacid and erect, over the months that you knew he was going to physically challenge you to capacity.
"See how she drips for you...How she squirms for you...," Copia cooed, petting your back affectionately with one hand and placing the other on his twin's shoulder in encouragement. "Give her what she needs, eh?"
Any resistance Perpetua had finally melted and he pushed forward, inching through your snug grip until your body jolted. Your back arched up like a cat from the deep sting and let out a barely restrained yelp. He froze mid-thrust, grunting and looking to his brother with a worried, rapidly blinking expression.
"Now when you feel her tense like that, or if you see signs or hear sounds of discomfort, just stay still and let her adjust. She will let you know when she is ready for more," Copia reassured him calmly. "Take the time now to see what she likes...Where she likes to be kissed and touched."
Perpetua seemed to consider his options for a moment before leaning down, pressing his hot tongue against your lower back and running it up your spine before latching on, digging his teeth into the meat of your shoulder possessively. And to his chirping delight you moaned, low and animalistic, fisting a the sheets and pushing yourself back until his punishing length was buried to the hilt in your spongy core.
Spurred on by your visceral reaction he snarled against you, rearing back and pulling you taut against him just as he'd seen his brother do, making you squeal from the intensity of being so impaled on his cock, clawing at his sinewy arms and clutching at the the spines of his wings a little too hard, gulping air and wordlessly pleading for mercy and for more.
"Look in the mirror, fratello," Copia gestured across the room, his voice full of affectionate pride. "Her lovely pussy takes you so well."
He started to move, tentatively at first, and the sinful sight of his shaft disappearing into your inviting hole, watching it strain to accommodate him, molding around him, was enough to to shatter whatever restraint he had left.
Perpetua growled loud with his maw buried in your hair, breath coming in hot pants against your neck. You reached back to tangle your fingers through his coarse fur, pulling hard in an attempt to ground yourself through every delicious, synchronized roll of your hips, eyes pressed shut and jaw clenched from the overwhelming pounding against that sensitive spot within. "So...Deep...FUCK..."
He adjusted his grip on you to free a claw, pressing the leathery pad against your clit in confident circles until your body bowed against him, a ragged cry echoing through the room as you shook with violent tremors.
The fluttering of your tight flesh around him, the quivering of your stomach under his thick palm, it was just as intoxicating as he'd hoped it would be, every bit as euphoric to know he could give you that much pleasure. You felt his rhythm falter and his strong body shudder weakly, and you heard him whimper as he lost himself in you. But you also felt him inflate, just beyond the tight ring of muscle that held him in place. You were just coming down, freefalling from the dizzying height of your own orgasm, barely aware of the steady stream of thick spurting seed erupting inside you when you felt it. And when you were left stretched beyond what you thought yourself capable of you could feel his heartbeat against your back thumping rapidly when a post-coital panic seemed to hit him as you both realized what had happened.
"It's okay...We're okay...," you whispered against his drooped ear, releasing your desperate grip on his fur so you could cup the base of his skull and hold him close. "You did so beautifully, Pet...Made me feel so good..."
"Bravo, fratello! Very well!" Copia's praised jovially. "You can pull out of her now, nice and slow-"
"He can't," you groaned, voice croaky and throat sore from your cries of ecstasy. "His knot...I'm...I'm stuck."
"Oh!...Eh...I had forgotten about that...," he chuckled, backing away awkwardly. "Well, while you two...relax, I will run a hot bath and gather some juice and snacks. You have worked very hard and I think tonight has been an tremendous success..." His voice faded out into the distance as you and Perpetua went limp, only held upright by the support of his wings wrapped devotedly around you.
.
"How do you feel, mi amore?"
You were scrubbed and polished, happily sandwiched between them under a mountain of soft blankets for what was left of the night, Perpetua already snoring loudly against your back. "Exhausted. And sore, but...in a really incredible way. Satanas, C. I thought he was going to split me in half."
"Hmph. Should I be jealous?," he sniped, but with a crooked smile peeking through the grimace.
You cupped his cheek with a hand that was still a little shaky. "No, love, no. I could never survive a steady diet of that. But it was interesting." You gave your husband and his twin each a tender kiss before snuggling in comfortably between them. "And some lucky size queen Sister is going to be a very happy girl."
