	A slick trail of pre follows you as you move through the woods, each step making your legs brush up against your quad-equipped package. The sensation of your own legs rubbing up against them sending out a spurt of pre with every step, your body still sensitive even days after that fateful lay with Rylai thanks to that damn ghost. Your ears perk up as you hear running water in the distance, the thought of being able to soak and relax your sore muscles hurries your step, and leakage on the dirt ground along with it. But as you draw closer you can hear another noise carried along the breeze, a voice carrying a beautiful melody, one with a perfect pitch that would belong to a finely-tuned instrument. A long dormant part of your mind wishes you to stay put, and not endanger that singer with your lewd form, but it's a part of your mind that disappears more every day, you push it aside and continue to creep closer to the singer.
	Soon you draw upon an opening in the treeline and come across a small lake, a river flowing both in and out of it so it maintains a steady level. And upon the shore you spot her, Slithice the Naga Siren, her eyes closed as she sings freely into the forest night. Her slick aquatic body easily shines in the night, any and all light gathering on her skin, making your eyes follow her curves from her admittedly compact chest, down to her incredibly wide hips that connect into her serpent-like lower body. You're mesmerized by the sight, unable to move an inch as blood starts flowing to your crotch, hardening up your cock as your enormous sack begins to stir. The gigantic cum factories you call your balls begin squelching cum into your sack, preparing itself for the lewd thoughts now running through your brain, you have to violate Slithice. Your thoughts are utterly consumed by corrupting this pearl of the sea, thinking of making her wrap up along her shaft and guzzle down wads of cum, making her belly grow up against your shaft as she sucks down your sperm. While consumed in your thoughts you don't notice her song ending abruptly, her eyes having drifted open and seen you in the edge of the clearing, your giant mast sticking ahead, and your horribly swollen package swinging underneath you.
	"Wh-what...is that you Mortred!?" Her face is twisted in disgust and fear at what you've turned into. Slithice's body obviously tensing up from your presence, preparing her to either fight or escape to safety. She begins saying something else, but you can't pull your eyes away from the way her mouth moves as she speaks, imagining how that mouth would feel underneath you licking the sweat from your taint. You let out a shiver as your lewd fantasy cause a small spurt of pre, it arcing through the air and landing next to Slithice, her face beginning to grow green at the debased display from your shaft. She chokes back her fear and glares at you, "I don't know whats happened to you, but I'll get help."
	The promise of someone making you get rid of your new growths fills you with dread. Slithice just doesn't know what she's missing out on yet. "N-nothing's wrong with this, I-I can even show you how good it feels!" Your voice is more panicked than you wanted it to be, and as you step closer to Slithice she recoils in fear, not believing you for a second. You leap forward to try to close the distance between you and her, but instead of her remaining still she slips into the lake to escape you.
	"It's time for me to go!" The slithireen starts to dip deeper into the water, you'd leap after her but you know your balls would only slow you down. But before you can curse your 'gift', you realize it's exactly what you need right now. Your shaft still hard from the lewd thoughts you had, you grip the base and start jerking your cock. Your hands pulling up and down on your flesh, causing your sack to swing back and forth, already sweating and sending drops of it into the lake before you. Picking up the pace you try to force an orgasm out of your cock, your hands becoming a blur, and your package's swinging slowing as it gets even further packed with your cum. As hard as you work your cock you can't help but feel like there's a blockage, something preventing you from cumming, all you can do is desperately abuse your shaft with your hands, until the thought of Slithice bathing in your cum drifts across your mind. Her scaly body completely submerged in it, every time she breaths she gets another blast of your stench-heavy fluids entering her, the overwhelming musk keeping her stuck in it. A shudder runs along your cock at the thought, and your balls hug up close to your shaft as they start firing along it, the large salvos of thick cum stretching your cockhole wide as you fire off into the lake. 
	While you had been working your shaft, Slithice had remained to watch, unable to look away from the display of carnal pleasure. By the time you had start blasting your sperm into the lake it was too late for her to run away anymore, your heavy protein-packed cum mixing with the water, gumming up the running liquid. Your cock fired off like a cannon, each blast of sperm pulling your package up against your body as you fired into the lake, making the once clear liquid turn whiter and whiter. Slowly your cock started firing less and less, you shuffling forward so even the smaller spurts still make it into the body of cum that was once purely water. Finally your cock stops cumming, you having knelt near the water's edge, pushing your cockhead into the water so not even a single drop misses your mark. Now all you have to do is wait.

	You were a fool to wait, you don't even know what you wanted to have happen but your curiosity has spelled your doom. You can't find any purchase down at the bottom of the lake, the clear liquid you could easily see through now replace with a heavy yogurty substance. Every time you try to breathe in, the air your gills pulls in is heavy and leaves the smell of musk stuck to them. Every now and then you feel a firmness in the white liquid, unfortunately it's always near your mouth, like a packet of salted goo it rubs against your lips as it drifts by, almost begging to get chewed up and swallowed. As if that all weren't enough, the thick substance is incredibly warm on your skin, beating even the natural resistance you have to water temperature it feels as though you're being cooked in it. As you struggle against the liquid your mind runs, just what happened to Mortred, why does she have a cock? Every time you take in a gulp of the white liquid you find it harder to focus on some questions, lingering on other thoughts, like how Mortred's chest has grown since you last met, or the sweet smell of the pre that was dripping from her cock. For a second you wonder how to get one of your own before fervently pushing it away, you are a noble Slithereen, not some cheap whore looking for pleasure. But as you say that to yourself you can feel yourself growing aroused, and it finally clicks in your hazed mind, this is all Mortred's cum. Her enormous ballsack had managed to fill the small lake you had just been bathing in earlier. You take a second to shiver, in fear you tell yourself, as your pussy leaks a bit more into your already sexual fluid-filled surroundings.
	But that second of shivering grows into several, unable to stop it you realize something is happening to you, your musk-drunk brain still a step behind everything. The shivers of pleasure travel along your body's length as the nearby cum soaks into your body, making your sensitivity spike. You feel it affect your breasts first, making them balloon out into two mounds of flesh and begin to point forward, your nipples turning into hyper-sensitive points that can even feel the cum-flow around you. The light fluttering of those tighter-wads of cum as they swirl around your new growth causing you to gasp and take in a mouthful of cum, the momentary lapse giving it the chance it needs to fill an open hole. Instead of spitting it out you find yourself chewing it, coating the insides of your mouth with Mortred's thick ejaculate before swallowing it all, the cum packed so thick that even after chewing it you can swear you hear it plop down into your stomach. At that your pussy quivers in pleasure, you reach a hand down to feel at it and instead find a horizontal slit, with some kind of ring developing inside it. You hesitantly reach a finger in but as you do the ring pushes back, and you feel your clit expanding, growing firmer and until you realize it isn't a clit anymore, you have a cock of your own. 
	You'll never be allowed back from your exile now, your old friends and family would be horrified at the sight of you, you know this for sure, but you have trouble caring about them now. Instead you focus back down at your new cock, hesitantly touching it with a hand, but the second you do it freezes up and your body is wracked with orgasm. While in those throes of pleasure you feel another hard shaft growing out from the ring, lining up beneath your previous one and smacking against it as it too cums. Reaching down you can't help but starting stroking your cocks as you add to your sexual fluid prison, as a pressure grows in your new genital slit. Just as it grows to be too much your new set of balls plops out and slaps against your shafts on their way out, the two orbs incredibly sensitive outside of your slit but far too large to fit inside of it. Slowly your cocks calm down, and you openly gasp for oxygen, gladly accepting the tainted musk now, a part of your mind now growing addicted to the taste of cum. You know who to thank for this, and you'll be damned if you don't pay her back.

	You grew worried at first as you stared down at the lake turned cum-puddle, had Slithice escaped before you could finish? There was no way for you to see, and you were growing antsy. But as time went by you found yourself relaxing, as you saw two arcs of cum, nowhere thick as yours, arc up from the lake into the air before coming back down. The knowledge that you had not only covered Slithice in your cum, but it had gifted her as well made you shiver in pleasure. Your perverse body started working itself up again as it could tell there was more fun ahead. As your cum factories went back to work, a figure started raising out of the water, making your sack shake and fill with a gush of cum at the sight. Slithice slowly swayed her hips as she left the water, your cum drifting off her slowly, leaving a cream-colored sheen in some places or sticking to her in small clumps. Each sway of her hips made her improved body shake, her torpedo shaped breasts lagging behind her hip movements but still following them, far beneath that hung two foot-length cocks and a sack containing two apple-sized balls.
	"I'd like to thank you Mortred~. If I had gotten away from here I'd have never gotten to taste that nasty essence of yours, it's quite 'filling' too. The first taste almost got stuck to my throat on its way down~." She looked straight at you as she said that, her tongue running across her lips to pick up whatever taste may remain there. "In fact, I think I want some more!" Before you can make a move, she does, her long body allowing her wrap around you. Her tail constricts around your cock, each squeeze flowing along your length like a wave as the tip of her tail wraps around your ballsack, firmly coiling around where your sack connects to your body. You lose your balance and your back lands against a tree as Slithice travels along your body, leaving her head snug up against your balls. There's a deep huff let out as Slithice starts rubbing her face into your sack, smelling the cum inside and running her tongue along your flesh. She brings her hands up and starts roughly squeezing your cargo, grabbing hold of it some times to rub her face deeper into your package, her ministrations actually helping your cum-production. As your balls start to fill again you can see Slithice's own ballsack begin to enlarge, it rubbing up against your shaft and every time she takes in a whiff of your now sweaty balls her package pumps up, your musk continuing to pervert her body.
	"Ooohh!!" You let out a loud moan as you feel Slithice run her tongue along the gaps of your balls, stimulating an area you hardly knew was sensitive. She digs in deeper, making you let out squeaks of protest and pleasure until you feel her face retreat from your balls, your sack now throbbing and coated with her saliva. The ministrations upon your body hadn't gone unnoticed by your cock, it leaking pre that mixes with Slithice's body, her already natural slimy' body now coated in not just your cum but your pre and ball-sweat. Her tail runs all along your body again as you hold your and her weight against the tree, her thick tail still wrapped around your cock but this time closer to the base, giving her more room to coil tightly around your orbs of cum. The tip of her tail flicks against your anus, splatting your hole with your own cum and reaching up to rub it in. You shudder in response to this, clenching your eyes and tensing your body to prevent cumming right then and there.
	Upon opening your eyes you see Slithice staring right back at you, a malicious look on her face. "You've done so much for me today Mortred, I feel like I should gift you with some nice, thick, Slithereen essence. Who knows, it might just stick~." Far too late you realize she had the heads of both of her cocks lined up with your own cockhead, your urethra still stretch from the filling of the lake. With zero ceremony she slams twin lengths in, each shaft returning the cum they're coated in to the hole it came from. The girth of both of her rods stretches out your urethra, a telltale bulge impossible to miss, even with your eyes blurred in pleasure. She sits there and rubs her twin-girths in and out slowly, each thrust in getting a tiny bit further as she stretches out your hole and sending your eyes further into your own head. A shlick is finally let out as her sheath rubs up against your cock, the rubbery flesh a sensation you've never quite felt before, but the same can be said of the two gigantic cocks seemingly growing in size as they bulge out your cock to a disturbing degree. There's zero friction as Slithice pulls out, leaving only the head of her dicks inside of yours, before literally sliding them back inside. Your normally hard cock little more than soft clay for her to rut her cocks into, those twin flesh pythons actively leaking pre inside of you. That same pre pooling up in your ballsack, mixing with your thick cum, unbundling it and making it so every thrust from Slithice sends waves throughout your package.
	She begins to pick up the pace, her now watermelon-sized sack slapping up against the bottom of your dick as she thrusts in and out, firing off salvos of her pre deep into your cock. Her lengths feel like two iron rods, pressing up against the inside of your girth in places you didn't even know could feel pleasure. Slithice stops her violation of your cock for a second, shifting forward into some form of doggystyle, leaning over your cock and looking up at you as she slides back inside again. But as she enters this time so does the tail that had been tickling your anal ring, it easily finding the room to enter, still slick with your cum and sweat that's been dripping from your taint. She fucks you from both ends like this, her cocks still seeming to find more room to stretch and going deeper inside with every thrust, and her tail slapping itself up against your distended prostate. Your balls are packed full at this point, no amount of pre able to fill them up anymore, so every thrust from Slithice squirts out around her length, each thrust letting out a squelch. You're desperate to cum but still can't even thrust thanks to your position on the tree, so you sit there while Slithice abuses your body, her thrusts growing more and more frantic as she nears her release.
	"O-oh! Here it comes you twisted, fucked-up, slut!" She heaps abused on your ears as she slams her cock in one last time, sending a tremor across your cock that ends in your sack. Her last thrust pushing her slit up against your own cock slit, making a seal as her balls hold up against your cock head and you feel the journey of each blast of cum, being pumped from her balls and into you. The seal between you refuses to budge as she pours cum into your already stuffed balls, a burning sensation in your sack as you feel it stretch beyond its previous limit, accepting her 'pure Slithereen' cum inside of it. The burning continues throughout your body as you feel it reach your shaft, the warmth bring you up to the edge of orgasm, and Slithice's tail fin now slamming against your prostate pushing you over. You can only let out grunts as both you and her cum, both sources meeting in the center of your dick before sliding back down into your balls, continuing to inflate them. Your package is continuously and hopelessly filled with futa-jizz, growing larger and larger until you can feel blades of grass rubbing up against your ballsack. You stumble against the tree, losing all strength in your legs and landing on your sack, it becoming bloated enough to act as a seat as Slithice comes inside of you while also knocking whatever bursts of cum you've produced back into you. A shlorp is let out and you shudder as Slithice pulls her tail from your ring, and slowly untangling from around your sack. She rubs her sheath's ring up against your slit for a bit more, as both your orgasms die down, trying to pack every drop of her cum inside of you.
	"Aahh...You look utterly fantastic Mortred, we will have to do this again some time!" A slimy plop is heard as the seal connecting you to her cocks is broken and she slowly slides out. She grabs her cocks and rubs them against your horribly distended sack, using you to wipe off any cum that remains on her, before patting you your ballsack. Each movement sends shivers through your sack, the cum inside filling you with such a need to be let out and such lust you can only grown in response to Slithice. "Have fun with that!" She gives off an extra farewell as she dives back into the cum lake, giving you a final shot of her pert cheeks as she's coated once again by your jizz.
