Chapter 4 - Du Couteau Sweat Session

Katarina breathed hard, her breasts straining against her tight leather shirt. Her cleavage glistened with sweat. Sweat ran down her face, curled over her jaw, slid down her neck and pooled in her tits; her armpits were similar, as were her inner thighs; not to mention her sweaty ballsack and asscrack which were even worse. The leather didn’t breathe, either, and it was almost soaked-through, with her panties in particular being simply drenched in warm, stagnant sweat. It was always muggy in Noxus, and what little skin Katarina had on display (just her face, her head enshrouded in a hood so she wouldn’t be recognized) was soaked. Her huge breasts heaved in her too-tight shirt and leather vest, her sensitive nipples rubbing against the harsh fabric. Katharina was sweating because she was running, and she was running because she was almost home, the Du Couteau estate within her sight, and couldn’t take it anymore.
 
Three months away from Noxus on military campaign, three months away from her sister, and she hadn’t cum in all that time. Her balls were like ripe grapefruits, stuffed into her too-tight pants. Her cock was a solid, throbbing cylinder bulging out of her tight leather pants. It had gotten more and more difficult to stuff her dick into her pants as the days crawled by, getting hornier and hornier. How she wanted to just reach out and grab one of the hot lieutenants and spend a few minutes in a private tent ‘discussing tactics.’ But Cassiopeia had taken care to make sure that didn’t happen. Katarina bit her lip and groaned as her cock bent slightly from her movements, but the solid steel rod in her urethra did not. Her urethra ached, unaccustomed to having such a large and cruel implement stretching it out for so long. So her teeth dug a little deeper into her lower lip as her pink-rimmed pisshole flexed slightly, trying to push the sounding rod out, to no avail. The sound was sealed in place by simple magic that Cassiopeia had promised to undo the moment she got home.
 
Katarina cried out in discomfort and bit down on her finger. Being in chastity so long was gruelling. The only reason she’d agreed to suffer the sound for so long was the promise of the nigh-unendurable pleasure she was running to receive right now.
 
She flung the double doors open and pushed, panting, into the atrium. “Cassie!” she cried, feeling beads of sweat rolling down her waist beneath her armpits. She couldn’t see or hear her beloved sister… but, her nostrils flexed… she could smell her.
 
Cassiopeia, frequently playful and always tricky, had been waiting for her behind the door itself. With absolute silence she managed to creep up behind Katarina before wrapping her in a tight hug with both arms, and her tail coiling around the redhead’s legs. Katarina let out a bark of surprise, then blushed and snuggled in as her sister’s large, warm breasts wrapped around her head. Cassiopeia was completely naked and reveling in it as always. Katarina shivered as she felt Cassie’s long, slimy tongue curl around her glistening throat, slowly inch its way up to her jaw, and then slip away.
 
Even before she’d been cursed into a lamia, Cassiopeia proudly flaunted her assets, especially her huge chest; her large matronly hips (which had only been accented by the addition of a thick tail); her plump and kissable lips; and the bitch-breaking, horse-shaming girlcock hanging between her legs, now upgraded to double barrels and accentuated with cute little nodules and ridges: none could mistake her penises as completely human, especially now that they jutted crudely from a delicious pink cloaca. The skin of this organ was bunched up into tiny wrinkles, taking the form almost of a human vagina were it not for its being stretched open by a set of mouth-wateringly filthy cocks stacked one on top of the other. They were so stupidly huge that she had no hope of keeping them within her pouch when she was aroused… as she was now. For her, it had also been three months since she’d cum, and her balls were insanely distended with the volume of cum and eggs inside them.
 
It was her sopping cocks more than anything that Katarina had smelled, the foul and sugary scent of her cockfog filling her nostrils. Katarina reached her hands over her shoulders and wrapped them around Cassiopeia’s neck, pulling the tall lamia down. At the same time she tilted her head back, way back, and the sisters pressed their lips together in a needy incestuous kiss. With Kat’s head that far back, it was like they were kissing upside-down, and they eagerly licked each other’s tongues while Cassie’s spit dripped down onto Katarina’s lips and rolled over her face. Katarina moaned, then pulled away for just a moment to spin in her sister’s grip, planting her chin firmly in Cassiopeia’s wonderful cleavage and looking up into her eyes. Katarina’s eyeshadow was expertly-applied, as always, making her green eyes glisten atop those pure-white pools rimmed by pure midnight. “I missed you,” she said simply, standing on tip-toes to kiss at Cassiopeia’s lips, and the lamia curled her arm around Katarina’s head and pulled her upwards to kiss her fully. Their lips parted and their tongues wrapped around each other’s, Katarina’s talented tongue fighting to dominate, but Cassie’s length and strength overwhelmed her as always, and her tongue was forced back into her mouth. Katarina felt her knees weaken as she was overpowered and she let out a desperate gasp of pleasure into her sister’s mouth. Cassiopeia forced her tongue past her lips, holding Katarina’s tongue against the floor while eagerly raping her mouth with the rest of it, and finally shoving her tongue a few inches down Katarina’s throat. The redhead gagged, all the strength in her knees failing as her sister dominated her so easily. How many had she killed, effortlessly, these last few months, only to be taken control of by her younger sister in these simple few seconds? She would have knelt to the floor were it not for Cassiopeia firmly holding her head, but also groping her fat ass through the cheeks of her tight leather pants. 
 
Then, just as easily as anything else, Cassiopeia picked her up and cradled her in her arms like a baby. Katarina’s thick cock had pushed a tent in her pants and was already sticking out by four inches, throbbing against her rock-hard abs. Cassiopeia swirled her tongue around her sister’s mouth before pulling back, eyes glimmering with delight. “Missed you too, slut,” she purred, goosing her sister’s ass one more time, making Katarina blush. She felt wonderfully helpless in the arms of this supernaturally-strong woman, and once again wrapped her arms around Cassie’s neck as the lamia slithered forward to the bedroom. The snake’s twin cocks were an angry red, pulsing and drooling an obscene quantity of ultra-thick precum, even her pre virile enough to impregnate an unwilling bitch at any time of the month. Her actual spunk was energetic enough to slop towards the nearest womb by itself. Cassiopeia wondered just how many women had gotten pregnant just by sitting on toilets after she’d used them. She liked to fantasize that every young lamia she saw on Noxus’ streets was her own spawn… and this incestuous desire had driven her more than a few times to take them into a dark alley and get them pregnant too, filling her daughters with more daughters. 
 
She shook herself from her fantasy as she came to their shared bedroom, knocking the door open with a harsh swipe from her tail. The door hit the wall with an enormous bang, the knob denting the wood, making Katarina giggle at the casual display of destructive strength. She kissed up Cassiopeia’s jaw, but the lamia only looked down at her with an amused smile playing about her lips. Cassie was also rather sweaty, Katarina able to feel the warmth and wetness of her sister’s armpit as she was held right against it. She leaned her head over and kissed at the side of Cassie’s breasts, moaning softly as she licked a perfect droplet of sweat from the side, leaving a tiny trail of spit behind.
 
Cassiopeia tossed her sister onto the bed, knocking the air from Katarina’s lungs as she bounced twice. “Oof!” When Katarina managed to sit up, she realized Cassiopeia had stripped her of her shirt during the fall, exposing Katarina’s huge, heaving breasts and cherry-red nipples, all streaked with sweat. Cassiopeia was standing near the bed, holding Katarina’s sweat-soaked leather vest in her hands. Cassie locked eyes with her, staring at her unblinkingly as she pushed the armpit of the vest into her mouth and sucked on it, emitting a loud groan and shivering as she did. Her long tongue snaked out and licked at the salt-impregnated material, her eyes fluttering closed in almost-orgasmic bliss, her entire being dedicated to sucking the sweat from Katarina’s filthy clothing. “If you like that, you’ll love my panties,” Katarina cooed, leaning back on the bed and hooking her thumbs into her pants. They were pretty disgusting too, absorbing all the sweat of three months of combat into them, and Cassiopeia was sure to enjoy them in time, but the silk-laced white panties overwhelmingly caught the lamia’s attention as soon as Katarina managed to free just the upper inch of them. The stench of sweat made Cassie’s nostrils flare, and she nervously licked her lips, dropping the vest to the floor and trampling it as she slithered forward, grinding it thoughtlessly into the floor. 
 
“I can’t quite get these off,” Katarina teased, flexing her muscles very slightly in a pantomime of pushing her pants off her legs. “My dick’s way too fucking hard after being locked up for so long, I can barely—hey!”
 
Cassiopeia was a predator, and was in that moment overcome by her animal lust. She reached down and flensed the material with her diamond-sharp nails in an instant, shredding Katarina’s leather pants into ribbons, then tearing them away. Before her eyes was her beloved’s throbbing prick, so masculine, the rod gracefully curling just slightly up, the skin covered with veins—such a powerful symbol of shemale energy jutting forwards, stretching to the limit a perfect white pair of feminine panties, the thin straps straining, digging into Kat’s legs as her huge erection twitched and throbbed.
 
At least, they’d been white when Katarina left. They were so completely soaked with twelve weeks of unwashed ballsweat that they’d turned grey and see-through, the redhead’s hefty nuts pulsing visibly behind the translucent material, little veins standing out of her fleshy sack as they struggled to contain such a long, pent-up orgasm. “I’m gonna cum like a fucking public fountain when you finally rape my ass open,” Katarina whispered, lying back and running one finger over her teeth. Cassiopeia didn’t say a word as she lunged onto the bed with her full weight, that massive tail making the mattress sink towards it, Katarina briefly feeling like she was losing her balance before Cassie shoved her face between her thighs and bit the fabric of the panties between her front teeth, then quickly, viciously, yanked them down her legs. Katarina yelped as she did, Cassiopeia dragging Katarina’s legs upwards before the panties finally slid free. The woman closed her eyes and greedily stuffed the disgusting underwear into her mouth, sucking loudly on the impregnated fabric, schhhh, schhh. Cassiopeia’s expression was the picture of hedonistic pleasure, her eyes rolled back into her head and her eyelids twitching. The taste was unfathomable. 
 
“Now come get a taste of the real thing,” Kat beckoned, her own eyes half-closed in seduction. Cassiopeia didn’t simply throw the panties away, but tilted her head back and swallowed them before Katarina’s eyes, making the redhead shiver in arousal, watching that bulge slide down her sister’s throat. Then Cassiopeia laid on top of Katarina, letting their large breasts squash together wetly, both sets slick with sweat, tilting her head to the side and locking their lips together, forcing her tongue into Katarina’s mouth and sharing the rank flavor of her sister’s panties with her. Katarina gagged on it, but kept her composure and kissed back eagerly, letting Cassiopeia’s tongue twist around her own as the lamia’s drool once again slid into her mouth. Gods, but Cassie’s mouth made so much spit… 
 
“Mmmmmnh, fuck me…” Katarina moaned, laying one hand on her chest and one over her forehead. She spread her legs slightly.
 
“Patience,” Cassie said, planting a tender kiss on her sister’s lips, and a string of spit as she pulled away. “I haven’t had anything to drink, my mouth is so dry…” she leaned in and let her tongue out six inches, running it through Katarina’s armpit. “Ahh… your sweat is better than water.” The tip of her tail began to rattle as she dug her face into Katarina’s armpits and heatedly made out with them, her eyes shutting from the stinging steam. Katarina squirmed in pleasure as the wet organ pushed into the sensitive cavity, the skin ever so slightly softer as it was meant to stretch. It was a deliciously-lewd kink they shared together, and Cassiopeia’s incredible tongue only made it that much better. Before long Katarina had to gasp out again as Cassie switched to the other side, making out with her other armpit, soon leaving both of them dripping with snake-spit. Cassiopeia panted, her tongue lolling out of her mouth, spit pouring down the tip in thick drops. Katarina held her hand under the dripping saliva until her palm was wet, then smeared it on her own face, moaning.
 
 Cassie retreated to Katarina’s nethers, now exposed, and with nigh-visible steaming clouds of musk. She grasped Katarina’s balls in her fingers and lifted them slightly to her mouth, tugging them out an inch and making Kat gasp. “H-hey! I’m pent up down there, that hurts,” and Cassie just smirked. “Y-you said you’d take the sounding rod out once I got home too.”
 
“Ah yes,” Cassie cooed gently, running her hand over the bulging underside of her sister’s huge dick, feeling the unnatural hardness of it as it stretched around the cruel steel rod. “In a moment,” she said, letting her eyes close again as she began to wrap her tongue around Katarina’s sack. Once, twice, three times she tied her tongue tightly, squeezing, firmly separating Kat’s testicles from her body, the redhead grunting loudly and grabbing fistfuls of the bedsheets, her expression wrenched in pain, but she didn’t tell her to stop. Denial and pain were magnificent for her. As Cassie tongue-tugged on her nuts, a single bead of white cream formed at the tip of her urethra, around the edge of the metal. She moaned, a vein throbbing on her forehead. It had been so long, and she was so incredibly sensitive… 
 
Cassie took one last long snort of Katarina’s ballscent before relaxing her tongue. She reached up and wrapped her fingers around the base of her sister’s dick, dispelling the magic. She did not squeeze, merely held Katarina’s cock in her hand to keep it upright while she stared at Kat’s face. For a moment the woman’s expression didn’t change, but then her eye twitched and her mouth fell open as her cock began pushing that fat silver dildo out at last, inch by inch, slowly at first but ejecting the second half of the rod in the blink of an eye. Katarina let out an enormous gasp of satisfaction, her urethra gaping open as Cassiopeia wrapped her mouth around the tip and blew. Katarina winced and grabbed a fistful of her own hair, tugging on her scalp to try and defray the unimaginable intensity of the sensations shocking through her body. Before she knew it, Cassiopeia had shoved her tongue straight down her urethra, simply replacing the hard rod with a soft plug, and Katarina screamed in bliss. It was a much more delicate instrument than the blunt metal, and it squirmed delightfully in the ultra-sensitive gape. Cassiopeia’s tongue was talented beyond compare, and so was the technique in her fingers, talent she once honed as a courtesan, expertly stealing cum from a dignitary’s cock even as she stole state secrets from his lips. Katarina’s asshole flexed as she felt the need to cum with those dainty, soft fingers sliding up and down her cock while that thick and long tongue was jammed down her dick. She could feel the tip of Cassiopeia’s tongue worming around in her balls, bulging out the walls and stirring up the cum inside. “Gonna cum,” she whispered a moment before she did. She felt the sludgy, pent-up nut she’d been storing for months suddenly shift, and Cassiopeia’s tongue retreated, replacing itself on Katarina’s balls but without Cassie having to move her mouth from the head. Katarina’s nut slammed into Cassie’s mouth in a sledgehammer of backed-up fuckslime, a brutal assault of off-yellow chunky spunk that rolled like syrup amid a chorus of moans. Cassie was used to swallowing things much larger, and even more foul, and she choked it down, dutifully consuming her sister’s sludge. Katarina roared, an impossibly intense orgasm washing over her entire body from her head to her toes, even making her fingertips tingle. Thick, stinking jets of semen erupted from her dick in crude gouts, each spurt the match for a normal man’s whole load.
 
When Katarina came back to consciousness, the first thing she did was jerk her hand over to her cock. Relief flooded her body as she realized the sound was finally gone. Not only that, but her hand collided with her prick with a slimy splat, and she looked down to see Cassiopeia slowly nursing the sludge from her dick. “Your cock’s almost as filthy as mine,” the lamia cooed, planting a kiss on the side, her lips covered in spunk. Katarina took a few more moments to return to full awareness, just enjoying her sister making out with her filthy fuckmeat. Almost half of Cassie’s face was streaked with slime but she seemed not to notice as it dripped thickly off of her forehead and gummed her eye shut. 
 
“I think I might have matched one of your orgasms for once,” Katarina sighed, heart still beating faster and head more than a little foggy, although that may just have been from the obscene smell of all the sludge she’d pumped out that Cassie hadn’t managed to swallow. It was delicious, enough to turn a chaste princess into a depraved cum-catching bitch with one whiff. Katarina closed her eyes and simply basked in the pleasure of it all, although she could feel a dull thumping deep in her huge dick, and she knew she’d want more soon enough. “Look how much I pumped out with you shoving that filthy tongue of yours down my dick…”
 
“You had your fun, now you owe me,” Cassiopeia cooed, holding her two twitching, dripping fuckrods over Katarina’s face. Those dicks had spent the better part of twelve weeks crammed in her pouch, which produced a clear slime that served as a natural lubricant and aphrodisiac. The smell of her dicks after marinating in that pouch so long was positively mind-blanking, especially as thick dollops of slime dripped onto Katarina’s face. Katarina reached up with one hand, wrapping her fingers firmly around the throbbing tip. The other hand followed, and with two long, slow strokes, she pushed the skin down, then yanked it back up. Cassiopeia’s foreskins peeled away, revealing months-old slime that curled around the tips, solidified almost to gelatin. With a turn of her pelvis, Cassiopeia angled her dicks down and placed them at Katarina’s lips. Her sister kissed them as she would kiss a lover, then wrapped her ruby lips around one and sucked, hard. Drinking her slime was a gagworthy event but she did it gladly every time, Katarina adoring the way the thick gel dripped down her cheeks to the bed. Like all of her sister’s fluids, there was more than just ‘too much.’ It filled her mouth, stuck to her tongue, obscured her teeth and gummed up her jaw. It was thick and sticky and vile, and with great effort, she managed to swallow it with a single foul glorp and a bulge sliding down her sweat-glistening neck, a packet of perfect cockslime send to her belly. Her eyes flicked to Cassiopeia’s middle, which was still hanging slightly with the weight of Katarina’s gallon of sperm she’d unloaded there. Already she felt another stirring in her balls, the need to breed building. If this was a good day she’d get another four or five full loads down Cassiopeia’s chugging throat, and take at least that much herself. When she had tongue-cleaned Cassie’s pricks, they were revealed as a dull red color with small bumps and flares. 
 
“Now my balls,” Cassie cooed, reaching down and pressing on her groin with her fingers. The small bulge under her dicks flexed, then slid upwards. Her cocks were nudged out of the way by a fat slimy ball pushing free… but nothing else. Cassie’s face was pained. “I can’t… quite… get the other one out… can you do the thing?”
 
Katarina smirked, nudging herself forward slightly and wrapping one arm around Cassie’s tail. Her fingers sank into her sister’s fat ass, leaving little white marks where they trailed. Then she wedged her cheeks apart and stuffed her thumb up her butt.
 
Cassiopeia groaned, her eyes popping out in pain, but her other nut also managing to slip free in a spray of disgusting slime. “Oh gods yes, that feels better… my balls get so painfully full when you aren’t here to drain them, darling,”
 
“I’ll drain them every day for the next week. We won’t leave this bed…” Katarina promised, rising to her knees, and shoving her face into Cassiopeia’s sweaty armpit, even speaking into it in between licks and sucking. “I’ll get the servants to bring us food, and I’ll eat it greedily while you fuck my ass open.” She was fapping openly, her foreskin bunching at the tip. She leaned down to Cassiopeia’s balls, making smouldering eye contact as she carefully took a mouthful of the slime soaking those nuts into her mouth, and swallowing audibly. “Gulp… Ah… If your slime tastes this good, I can’t wait to deepthroat your huge dicks and let them spunk in my guts.”
 
That simple little statement made Cassiopeia more aroused than she’d been all day yet, and she acted on it quickly. She laid down on the bed and then tugged Katarina’s round ass onto her face. The redhead laughed, then spanked her ass as she adjusted her legs to sit one on either side of Cassiopeia. The younger sister began eating her ass with a passionate lust, running that slick tongue over the twitching, flexing donut as often and as sloppily as she could. Katarina squirmed, feeling her cock twitch every time Cassie’s tongue dug into her hole, and she groaned as she felt her sister so effortlessly milking another orgasm out of her. “God… you’re entirely too good at that… fuck yes, tongue me! Work my fucking ring, you ass-eating whore!” Katarina ground her asshole into Cassiopeia’s face, twerking like crazy, her muscular ass jiggling gently against Cassie’s cheeks. Sitting on her face, Katarina found herself in the perfect spot to reach down and grab Cassie’s fat milkbags in her hands, running her fingers along the sweaty undersides. She lifted them up, letting them fall back down with wet smacks and obscene jiggle, only to repeat the process half a dozen times before leaning in, Cassie’s chin pressing into her ballsack. She managed to stuff her face into her sister’s dank cleavage and snorted the sweat from her skin, huffing her tits, filling her lungs with her stench. As she did, Cassiopeia began plunging her tongue into her dark star, squeezing the hole open and prodding expertly at Katarina’s prostate, making a chill run down her back. She reveled in the feeling of her hands sliding across the moisture-slick underside of her sister’s giant breasts, her fingers coming away musky and wet. 
 
With a loud, firm spank, Cassiopeia pushed her sister off her face, wet with her own saliva, and moved Katarina down to her own groin. Katarina found herself dick-to-dicks with Cassie’s meat, seeing just how deep those fuckpillars would reach in her own body if Cassie was to go deep enough to clap her balls against her ass. She cooed as she pressed those cocks to her belly. “It’s been too long, my darlings,” she whispered. They were more than big enough for her to wrap both arms around and embrace like a long-lost lover, the tips jamming themselves up in her breast-pits and smearing obscene volumes of grease everywhere; she giggled. Slowly and expertly, Katarina rose up and laid her asshole against Cassiopeia’s twitching pricks, head tilting back slightly as she did. “They feel so warm… and so slimy. I want to feel them rip me open.”
 
“In due time, I will fuck you… but first you pleasure me in the way only you know how to do,” Cassie said, licking her lips. Katarina gritted her teeth and smacked her ass as she began to sink onto those dicks. Her doughnut-asshole eagerly swallowed both thick cocks, well-trained by years of ruthless fucking into a hole as hungry and wet as any pussy. Katarina felt her asshole twitching rhythmically in time with her own heartbeat, squeezing Cassie’s dicks as they pushed through the muscled ring. 
 
And as Katarina focused on inserting her sister as deep as she’d go, Cassie slinked her fingers around and tugged on her sister’s cock, bending it downwards towards her own cloaca. Inch by inch they closed in, until finally Cassie gasped, feeling the tip of her sister’s dick slide into the wet and slimy hole. “Sssssssss.” 
 
“You like that?” Katarina panted, looking over her shoulder, her ruby hair dazzling over her back. 
 
“Yesssssss,” Cassie groaned again, tensing up as Katarina pushed her cocks even deeper into her ass even as she spread her cloaca open. This truly was as sensitive as a woman’s vagina, and kept in a state of perfect wetness by her lubricant. Katarina felt her cockhole burn as the lube smeared up against it, but with one final push she managed to stuff as much of their dicks into each other as she was going to manage
 
“Oh fuck,” Katarina swore, her eyes shut tight as she felt an orgasm threaten to roll over her. She held it back as hard as she could, wanting to pleasure her sister’s hole but almost overcome by the intensity of what they were doing. “I can f-feel your pussy twitching around my dick, mommy…” she pushed out, and Cassiopeia let out a naughty chuckle. 
 
Ah, so that’s how it was going to be today.
 
“Mommy’s little slut loves fucking her hole, does she?” Cassiopeia crooned, running a bent finger over Katarina’s cheek. 
 
“Y-yes… mommy… god it feels so good being this deep in you…”
 
“And you as well, darling.” Cassiopeia laid her hands on her sister’s waist and shivered slightly. Katarina’s waist was legendarily thin, and she could practically feel her own cocks throbbing through the woman’s skin. “Your asshole is really clinging to me today…”
 
“It feels… like I’m gonna explode… with mommy’s big fat cocks so deep in my asshole,” Katarina panted, tears rolling down her cheeks. “Mommy… please nut in my fat ass so that I can cum too.”
 
Katarina always managed to get her sister insanely turned-on when she did this, and Cassiopeia was within an inch of cumming after all the foreplay even before Katarina brought in the mommydom. The lamia groaned loudly, almost a roar, as she felt her fat slimy balls finally clench and her orgasm began.
 
Her dicks were pressed firmly against Katarina’s prostate. She could even feel her sister’s heartbeat through the little button. Katarina’s sperm had been thick, but nothing like this. Cassiopeia’s pent-up load barely shifted at all; far from ropes and strings, Cassie’s orgasm was like a baking-soda volcano, a mountain of white-hot tar bubbling from her tips. Her nut was as dense and sludgy as wet concrete, and had the same effect in Katarina’s ass, gluing itself to her walls in ridiculously-thick layers of sperm. Cassiopeia’s overexcited semen wriggled into Katarina’s inner walls in an attempt to impregnate something, and they even found their way into Kat’s prostate, thinking it was some kind of egg. “Mommy! Ah!” Katarina screamed, throwing her head back, her hair dancing down her back as she bounced and twerked, feeling herself begin to cum as Cassiopeia impregnated her shemale womb. Her hungry asshole greedily devoured every inch Cassie could give her even as huge amounts of steaming spunk poured from the imperfect seal of her ring around the twin dicks. “I can’t stop it,” she whined, a lewd and disgusting schlorp of thick, heavy sperm oozing from her backdoor even as Cassiopeia pumped more and more in. Katarina’s hands jerked to her stomach which was beginning to plump up, a full gallon and a half of creamy nut pouring ceaselessly into her asshole and sliding up her system. “I’m gonna,” she said before being silenced, her cheeks bulging, and then her lips bursting open with her sister’s overflowing orgasm. Katarina gagged, black lines of mascara running down her face as semen too thick to swallow pumped itself out of her throat and down her body, smearing her chest and rolling over her dick in obscene gobs. Katarina coughed it up, her eyes rolling back, her own orgasm continuing.
 
Katarina’s dick was as deep in the foul, sloppy hole as it would go when she did. It was completely surrounded by Cassie’s slime, which was a lot cloudier than it normally was, for Cassiopeia’s precum had leaked into her pouch every time she became aroused these last months. It felt like sticking her dick into warm jello, and she didn’t mind it one bit. Cassie’s cloaca slammed shut, squeezing her dick as hard as it could, almost literally milking her as she moved back and forth. Just as Cassie’s squirming gametes mated with her button, she felt the hardest orgasm of her life shock through her body like lightning. Almost instantly she was cumming another two or three dozen ropes, and she wasn’t shooting air by the end either. Each twitch of her dick precipitated a full, long, gooey cable of densely-packed semen gushing right into her sister’s ‘pussy.’ Even as it bubbled from her own mouth, Katarina doubled-down on fucking Cassiopeia silly and packing her cloaca as full of spunk as she could manage. 
 
The two women collapsed into each other’s arms, panting (mostly Cassie) and coughing up sperm (Katarina). Cassie smothered her sister in her sweltering, sweat-steaming cleavage and Katarina began kissing every inch of exposed flesh, finally wrapping her red lips around Cassie’s nipples and sucking. Katarina reached down and stuffed her hand between her legs, pulling it out and wiping the stink off on her skin before lifting her hand to Cassie’s nose. The lamia took a deep, shameless snort of her musk, and shivered.
