Had a VERY hot thought about Copviiia and needed your opinion/thoughts on it. This is going to be a long one (sorry I got too caught up)
Okok, so I feel like Terzo loves the twins so incredibly much and it’s impossible for him to pick a favorite. The twins would obviously fight for Terzo’s attention or try to “one up” each other. But honestly Terzo can’t decide because they’re both so incredibly attractive and arousing.
Imagine this, every time the 3 have sex Terzo just takes it all. Their usual position is this: Terzo’s lying on his back with his legs spread and hardened cock standing/twitching proudly. Copia usually works on Terzo’s cock, from sucking it to (usually) sinking his cunt down on it and riding Terzo just the way he knows he likes it. Copia is very experienced with Terzo’s cock since he’s been around the longest, so he knows just how to move. Meanwhile, Perpetua is grinding down Terzo’s face. He’s throwing his head back and moaning loudly whenever Terzo’s tongue fucks his clit or finds a way inside. The thing about Perpetua is that he’s extremely vocal. He’ll whine and moan at anything which turns Terzo on even more.
However, there are certain occasions where they do swap. How could Terzo decide who’s his favorite? There’s Perpetua who can take many orgasms and he’s extremely loud. He practically comes whenever Terzo’s cock is halfway inside his pussy, versus, Copia who goes absolutely ham on Terzo’s face. Copia will always try to go slow at first, but the pleasure is too great, so ultimately he grips Terzo’s hair and fucks his face with such a rapid pace. Terzo would honestly loved to be suffocated and pass out by either of their cunts. Maybe on some occasions he has. Both the twins love to get their cunts filled, whether it’s by Terzo’s cock or tongue. And Terzo has his hands absolutely full he just doesn’t know what to do with them! He could grip Perpetua’s hips and fuck up into him roughly OR he could grip Copia’s hips and bring him down harder onto his face. Either way, Terzo enjoys being used by both the twins no matter who’s on his cock or his face.
Sometimes, whenever Terzo’s cock is spent but the two are still incredibly horny they’ll give Terzo a show and scissor each other. Moaning each other’s names or even Terzo’s name. This usually does the trick and Terzo is hard once again. Ultimately, whenever everyone does calm down, Terzo lies between them and both twins are on Terzo’s side. He’s extremely out of breath, but absolutely so satisfied by their handiwork. Copia usually stays quiet after sex, tracing lazy patterns on his uncle’s body occasionally giving a quiet nod, a shake to the head, or a quiet hum when either of them were talking directly to him, meanwhile Perpetua engages in a soft conversation with Terzo. Either way, Terzo makes sure to include both his favorite nephews. Sometimes however, the moment gets ruined whenever one asks Terzo “so who was better?” And just like that, the two are fighting to see who was Terzo’s favorite. But honestly? Terzo simply can’t choose. He loves how vocal Perpetua is and loves how that man comes at practically anything. But he also loves how skilled Copia is and how whenever Copia is lost in pleasure he simply uses Terzo so roughly like he’s nothing but a fucktoy. He usually just lets the two tire themselves out and cuddles with them both once the two are asleep.
this whole idea is so fucking good.
i’m so stuck on the detail of terzo just taking their pleasure, allowing them to do what they will, even though he wants to chase both of them. afraid him bucking into pet, or licking into copia more would be seen as competition. terzo wants them both so badly, but the two get off on the competition more than they let on.
copia and pet share a heated gaze across terzo’s writhing body, copia grinding down into terzo’s mouth, his moans being drowned by his pussy. pet lifts up on terzo’s cock, his cunt slick and tight as he swallow him down, seated in his lap, grinding his hips while his hands slide up terzo’s torso to pinch at his nipples.
terzo moans from the stimulation, letting up on copia’s cunt to mutter a curse, before resuming.
mouth slack, pet mewls wantonly, slick gushing over terzo’s cock. terzo’s hands twitch at his sides, desperate to grip at the two of them, but not having enough hands to grab them both with. terzo’s tongue works tirelessly against copia’s pussy again, his hips thrusting up into pet, body on overdrive as he is stimulated from both ends.
hips snapping against terzo’s mouth, copia grunts as he works against him. terzo’s tongue is relentless, flat against his clit, cunt dripping into his mouth. his hips falter as terzo groans into his pussy, catching pet’s eyes as his twin swivels his hips, terzo’s cock undoubtedly twitching inside of him.
“fucking hell, feels so good like that!” pet gasps, curls bouncing as he takes terzo deeper into him.
with renewed vigor, spurred on by terzo and perpetua’s shared pleasure, copia lifts up, listening to terzo pant as his pussy is removed from his mouth. copia leans down, confident and filthy, his lips parting slightly to spit into terzo’s waiting mouth.
terzo moans then, swallowing down his nephews spit, mouth lifting to chase copia’s pussy, his hand coming to grab onto his hip, bringing him back down. triumphantly, copia seats himself once more, allowing terzo to lick him from hole to hole, cunt soaked and holes loose from terzo dipping his tongue inside.
“terzo, terzo, please!” copia whines, thighs trembling around his uncle’s head.
pet’s hips never still, even as his thighs threaten to give out, scrambling for purchase against terzo’s chest as his orgasm approaches. watching his twin be so bold as to spit in their uncle’s mouth sends pet over the edge, lifting to grab at copia, who returns his desperation tenfold.
without being able to see, terzo knows exactly what they are doing due to the telltale sounds of their mouths slotting together, spit slick and dirty. they moan into each other, chasing their release with terzo’s body, him having being forgotten beneath them as nothing more than a toy.
pet cums first, cunt spasming and effectively milking terzo’s cock, he holds onto copia for stability as he trembles. their kiss parts, desperate whines leaving perpetua’s hungry mouth as copia holds him through his orgasm.
terzo feels like his body has gone into shock, his cock aching in the tight heat of perpetua’s pussy, his face soaked with copia’s pre, and now he can feel the warmth of him squirting, the rush of fluid into his mouth as he moans into it, gorging himself completely on his boy.
copia’s pussy clenches above him, the twins now holding each other as they moan tiredly through the aftershocks, completely having forgotten about terzo’s pleasure until he cries out beneath pet, cum flooding his cunt, twitching painfully hard inside him.
shifting to lay next to his uncle, copia finally allows terzo to breathe, and watches as he arches and groans, emptying into his twin. terzo grabs at pet now, grinding his cock into the boy, the last of his spend gushing inside pet. 
whimpering from overstimulation, and trembling from his climax, pet curls up into a little ball on terzo’s chest, allowing him to slip his cock out of his pussy as it softens. pet’s hair splays messily around his head, arms curled around terzo’s neck, still straddling his hips.
“feels good inside me, tez…” pet mumbles, nuzzling into terzo’s neck.
humming, terzo reaches for copia, stroking his thighs, mumbling some soothing praises before lifting his arm and welcoming him under his arm.
panting in unison, the three calm down slowly, kisses being shared, soft caresses on each other’s bodies, no one being forgotten in their little bubble of warmth.
“was that good, zio?” pet asks, voice small, always seeking approval.
“perfect, amore, both of you.” he kisses pet’s head, “always perfect.”
copia makes a little sound high in his throat, and nuzzles his face into terzo’s side.
“ti amo…” he whispers, hand curling into perpetua’s hair.
“ti amo, sweet boy.” terzo whispers back, smiling down at his boy.
perpetua giggles, leaning over terzo’s shoulder to catch copia’s lips in a kiss. they sigh into it, easy and sweet.
pulling back, pet smiles slyly at his twin. “love when you kiss me like that.”
“love kissing you.” copia mumbles.
terzo just chuckles, rubbing at pet’s back while his other hand draws shapes on copia’s arm.
the two smile at each other before turning to terzo, both nipping at his jaw with kisses, giggling quietly as terzo shivers from their ticklish mouths.
“love kissing you too, zio.” copia confirms.
terzo hums, squeezing them both softly. “you’re going to be the death of me, little ones.”
closing his eyes, finally, terzo settles for a while longer, putting off their clean up ritual as he listens to the twins bicker over who gets terzo’s cock next time, and who can taste terzo’s cum once they clean up.
they settle on the only fair option, copia licking their uncles cum from pet’s pussy, and spitting it back into pet’s greedy mouth. all the while, terzo fights his body to hold an erection so close after his last orgasm, wanting desperately to use them both all over again.
