#1 of Assorted shorties

Ok, I'll be honest: I wrote this one just to get it out of my system. It's essentially a fuckfest born because I was browsing E621 and some of the tags insipired me enough to spend a couple of afternoons pumping this weird stuff out. As a wise man once said: 'twincest is wincest', and I wanted to give my contribution to the genre with a new couple of characters, two beautiful and tremendously naughty twin lizards with a passion for going to the extremes.

Hope you like it, I'm not sure how it came out but I felt like celebrating the servers coming back up today.


As she was sleeping peacefully, Andrea began to move and shake, her dreams not so calm and tranquil anymore: on her chest she saw a boulder that weighted her down and didn't allow her to move at all, her breathing was heavy and the air was laden with a scent so sickly sweet that she couldn't help but seek a single gasp of fresh oxygen. Her dream was cut short then and there as she woke up from it and saw that on her chest there was really something, but that something wasn't a boulder: it was her sister. Not even wearing the thinnest of clothing, as naked as the day she was born, the green lizard was resting on her chest, legs spread wide and with her puffed vent pressing against her sister's snout, the scent of need soaking through her scales. Andrea grunted as the weight pressed down on her breasts and squished them hard but in a somewhat pleasurable way if it was even possible, or maybe it was the smell of her sister's need that made it feel good.

At the same time, she felt wetness on her own crotch which meant that the same need had pushed Helena to jump on her while she was still sleeping and bury her face in her crotch, soaked in sweat after a night of apparently restless sleep and bad dreams, which culminated in her sitting on top of Andrea, huffing hard at the musk of her nethers. Andrea sighed and slumped back on her pillows just as her sister began spreading her slit to lap at the content hidden within, the feminine fluids and the ones that were less so. With every lick Helena prodded just a little bit deeper, with every breath Andrea made, their arousal grew to higher levels, not stopping, not wanting to stop in the least despite them being sisters, but that was another matter altogether. Helena pushed back a little and squealed as her vent spread on the snout of her sister so pleasurable she could help but come a little and coat the green scales pushing inside of her in more fluids and shove her own deeper still. Andrea hissed and opened her mouth and did the same thing, lapping at the same kind of arousal and drawing more pleasure from it than her sister.

Their licks grew frantic as the two kept going and didn't want to stop or to come, building a massive climax together, second after second, one tongue for one heated vent, each tending to the other's need but at the same time, another kind of desire made Andrea grew ever more frantic. Her breath became laboured as she struggled to hold something in, but her sister knew what she was trying to do and she didn't want her sister from holding anything back from her, nothing at all. Helena grinned with her snout half buried in Andrea's sopping vent and started moving her tongue in slow circles, teasing all the spots that made the other lizard squeal and writhe in pleasure every time for long agonizing seconds. Her efforts and her tricks worked and the muscles that Andrea was clenching to hold herself back gave in to a small climax, a mere second, a taste of what would come later, but enough to make her lose control. From the very depths that she was lapping at, Helena felt something rise and push those soft folds apart, hard, musky and terribly in need of attention. So, she opened her mouth and welcomed the shaft that began to grow inside of it, reaching for the back of her throat faster than she could pull out and look at it in all of its glory. Andrea snarled and pushed her sister's head down and against the lips of her vent to prevent her from taking her mouth off her still growing shaft. She felt the tip slither down, lower and lower inside of her until her out of place malehood was poking through her stomach and she sighed in relief.

Helena's eyes widened in a mix of shock and pleasure as her sister began pumping something directly inside her stomach, wave upon wave of fluids that she knew wasn't seed at all, far too salty and briny to be her essence. Andrea hissed yet again with every gallon that her bladder emptied inside the other lizard, filling her stomach with sloshing waste. She would have felt bad hadn't she know that Helena had a knack for such a thing and the vent shivering with an ever growing need right in her face was proof of it. Though a little pissed that she had been woken up and forced to grow hard inside her sister's mouth, Andrea couldn't let her so needy or backed up herself so, while her shaft pumped more piss inside that already full stomach, she resumed her lapping, inserting one lone finger up that heated vent for more stimulation. Helena couldn't take much more than that: her nostrils were swimming with the musky scent of her sister, her mouth spread painfully by that wide shaft that was so deliciously covered in slit-fluids and her stomach so heavy with waste that she couldn't take much more. Helena clamped down on Andrea's cock and came, alone, forgetting about their previous intention of reaching that height together and her entire body spasmed and shook with the throes of climax. It was Andrea's turn to smirk now: her sister's folds quivered before a small gush of white pushed from the depths, splattering on her face in small waves that thickened by the second. An equally large shaft pushed her out and plopped on her chest, growing and stiffening by the second, an almost identical copy of hers and spraying waves of pearly white seed between the two of them, coating their belly scales in thick, pheromone laden spunk. The lizard on top squealed as best as she could with her maw so full of cock, but the calls reached Andrea nonetheless.

Still a little groggy from being woken up like that, she began pumping in and out her sister's mouth, feeling the scales of her throat spread and her muscles contract or relax with her moving shaft, the girth of it enough to make her look like she was swallowing a baseball bat all the way down her bloated stomach. Andrea grabbed at Helena's hips and moved her own, mashing her slit on Helena's snout time and time again while her shaft hardened after emptying her bladder's contents, the tip dipping in that briny fluid whenever she bottomed out in that welcoming mouth. Andrea's pumps grew erratic, she lost her rhythm, the pace she set up as her sensitive shaft fought with the contractions of Helena's throat. The other lizard's cock was just as hard and spurted weakly small gushes of seed on her chest, adding mere cups to the gallons she had already wasted just as Andrea bit her lips and mashed her crotch on her twin's face one last time and contracted every muscle in her body. Helena's stomach was bloated and heavy with piss but it still welcomed the flow of spunk Andrea was pumping inside, making it grow even more, the bulge squished between their bellies and sandwiching her cock under it. Long minutes went by, Andrea's climax made Helena's own pale in strength and duration so much that the massive dome of her stomach was pushing her up and away from the bed, pinning her twin under her. Gallon after gallon, Andrea pumped still and only when the five minute mark ticked and the alarm clock rang loudly she sighed in relief and pulled out of her sister's mouth. A small waterfall of mixed spunk and piss washed over her crotch and stained the bed and a moment of cleverness allowed Andrea to sneak out from under the dome that was her twin's bloated form.

"Goddamnit Hel... how many times I told you not to wake me up like that?" Andrea was more on the annoyed side than angry and didn't want to admit that she liked that. Less than one second later she felt glad that she had slithered out of the bed as Helena lost control of her own bladder and yet another puddle spread on the bed, adding to the many stains that were on it already. "Come on, clean me up before I get angry."

"Sure thing." Though heavily bloated and full, Helena opened her mouth once again as her sister stepped in front of her.

The glazed eyes of the pregnant-looking lizard fell on the shaft that she had just sucked and that was about to clean one more time: it was thicker at the base than at the tip, spreading her sister's slit wide enough to look even more lewd, thick enough to make two hands meet at the middle impossible, keeping that cunt breaking girth throughout the twenty seven inches of length and tapering only at the very end. Her own was just shy of fifteen inches and not nearly as thick, but for other girls she was already bigger than more males, not to mention the monster of her sister's. Andrea smiled and caressed Helena's head as her tongue sneaked out and began lapping at her cock with careful yet desperate licks, dragging the wet muscle all over her flesh and cleaning it from waste and seed alike in long strokes that told her that someone wasn't satisfied enough. With a minimal amount of coaxing, Andrea made her twin turn around, her belly wobbling so perfectly under herm her breasts swinging just as nicely and settling in place as she pressed her entire body on the bed and raised her rump in the air, tail draped on her back to bare that still sopping vent where a mismatched cock poked out and dripped spent seed. If there was one thing that Helena had over her, was her chest: whereas she had a modest C cup, Helena had a nearly impossible EE cup that on a reptile was maybe more out of place than her own cock. It was normal for her to tease Andrea with tight bras or no bras at all and the result was more or less a rough ploughing just to put her back in place, which by the tenth time it happened, was clearly a ploy on her part to make Andrea rail her in every spot of the house. Those bountiful breasts were squished on the bed and made Helena wince in pleasure as Andrea teased her vent with that mammoth length and made her shiver even harder than before. Andrea grinned and pushed the tip of her shaft against her sister's vent, just below the spot where Helena's own poked and pushed deep, one foot in one single thrust and shivering herself with how heated and wet she was, the first waves of spunk lubing her way in with exceeding ease.

She was feeling the blood rush to her sister's cock to keep it hard, the heat of her folds wrap around her pleasantly and the moans of a full lizard that was about to be a little more full than before soon enough. Andrea didn't wait for the other one to prepare herself, nor she took it slow, her thrust were rough, long strokes in which she pulled out almost completely and then slammed herself back in, adding inch after inch with each one. She was bottoming out once more within the minute and Helena was squealing and moaning so loudly the sounds matched the squelches of her thrusts and the slaps of wet scales on wet scales. The roughness only made it more pleasurable for her as the girth of Andrea's base was almost impossible to get used to, no matter how much she railed her or rested inside her vent for hours on end. The second climax didn't come as soon as the first one, not by a long shot: it was a long, calculated, methodical rut, where Andrea made sure to make Helena come over and over again until her cock shot only blanks and the blankets of her bed were white with seed and nothing else and the clock told that they had been going on for close to thirty minutes already. Andrea hilted herself and then bit on her sister's neck, marking her as her own one more time as yet more gallons of clear spunk rushed from her to flood Helena's chambers and added pound after pound to a form heavy enough already. Time ticked by slowly and when she was done, Helena looked far more pregnant than before, a dome well above three feet in diameter pushing her scales apart and giving her a look so motherly on that five feet five frame that Andrea was tempted to make her a mother for real.

"Come on, let's get breakfast."

"Ok!"

Helena needed a little bit of help to get on her feet and when she was standing, at long last, her weight forced her to bend backwards and that belly pinned her still erect cock down, letting it drip the last remnants of her testes on the floor. Andrea didn't bother with cleaning up the bed and headed for the kitchen, sitting on the comfy chair while she waited for her sister to walk in and begin to cook for her. It was delectable to see a pregnant female, though not really so, cook and move about the kitchen, leaving a thick trail of spunk on the floor wherever she went to add to the old ones from the days before.

It wasn't always like this, in fact, there was a time in which the two couldn't even bear to be close to each other, living on opposite ends of the city, but their parents deaths had made that life change dramatically. They hadn't been able to hear their last words and they imagined how lonely the other would have been had Andrea or Helena died just as suddenly and so, they decided to move in together, spend some time, catch up. The grief, the fear of losing the other and be alone, pushed them over that line that must not be crossed and it slowly evolved into the situation they were in at the moment. Both still wondered just how it all happened: it was just one kiss at first, then a long hug, then holding hands to feel closer, then sleeping together and it all went downhill from there, a rush of feelings, pent up anger and need that pushed them closer still and changed everything.

"Want some juice with the eggs?"

"Sure." Helena held up the glass fill with orange liquid and put the plate with her sister's food on the table, right in front of her own and sat down, shivering as her heated vent touched the cold chair and the constant flow of spent seed pooled under her. "Do you need to get to work today?"

"No, I've not used my days off this month and so the boss told me to get some rest." Helena smiled and rubbed her bloated stomach with one hand, drinking from her own glass with the other.

"Is that why you woke me up like that?" She nodded. "You know that gets me in the mood for the whole day." Another nod. "So, you're telling me that today you want to be a cock-sleeve? Take me again and again until you can't move anymore?" Helena nodded one last time and came a little: she knew exactly how the day was going to go down, they both knew, there was almost no reason for Andrea to even ask, it wasn't as if this was the first time Helena had done it or asked for that treatment: she got a weird passion for being used like that, to be taken time and time again, filled and be forbidden to empty her aching bowels. "Then I expect you to use the plugs, I'm not willing to get the carpets stained today."

"Alright." She got up and opened one of the drawers in the kitchen, where instead of cutlery, there were almost a dozen plugs ready to be used, a statement of how much she asked for such a treatment to Andrea and how much she loved being full.

"No talking for the rest of the day either, I only want to her your moans or at best you begging for more, am I being clear?" There wasn't an answer, only one silent nod, as it should have been. Andrea smiled and stared at her sister as she spread her folds and jammed a large plug, just an inch less thick than her cock and one up her tailhole as well, for later. "Good pet." Helena smiled and got down to finish her meal, eagerly awaiting for an order or anything her sister might want to do to her.

Andrea finished her breakfast and walked over to her office, a small room at the end of the corridor, where she worked with on projects for high rise buildings and other landmarks. She was something of an established architect, a good one, with two famous spots in the city bearing her brand and style, but she didn't live in an expensive loft and didn't have a firm to her name: she still lived with Helena in the old apartment they had first rented after deciding to get but her work was amazing nonetheless and allowed them to live comfortably. Helena worked, she didn't need to but she liked what she did.

Sitting down on the ergonomic chair, Andrea told her twin to get on her knees under the table and pull out her tailhole plug, to which the other lizard obeyed immediately and within the minute, she had her cock buried almost to the hilt inside her sister's rump, relishing in the softness of her walls and the warmth they provided. Helena rested on a special seat just for her, custom made by a friend so that she could spend time with that thick cock spreading her wide for hours and not need to move. Just as all the other times, Andrea worked on her projects while she humped lightly at her sister's tailhole, keeping her on the edge or bringing her over it whenever she felt like it, perpetually hard in that warm heaven of hers. The floor of the office was in no way less stained by seed than the rest of the house and Helena made sure to add more as her body, so terribly worked up and full, refilled itself over and over. By the first hour of work, Andrea was thrusting wildly, making her cheeks clap perfectly whenever their bodies met and Helena jacked herself at the same time. As her climax hit, her smaller cock shivered and sprayed its load on the wooden floor, long, thick ropes of virile seed, wasted in wave after wave. Her endurance and stamina were severely undermined by her need to be filled over and over, but her production was not and so she came time and time again, turning the floor into yet another white mess while Andrea painted her walls with her own seed. Somehow she never seemed to run out of spunk and that was another reason why Helena teased her so much, she just wanted to see if one day she could milk her dry but such a day still hadn't arrived. Andrea snarled and spurted the third load of the day, making her squeal and beg for more with every pump, every gallon of spunk added to her pregnant form before the flor dwindled and she resumed with her slow humps and work. By the third hour, Helena was moaning with every single breath as her stomach had welcomed well over fifty gallons of seed and Andrea sighed, emptying her bladder for a second time that day and making the insanely big belly bloat one or two inches larger under the table.

At that point, Andrea got up and rushed to plug the abused tailhole with a large toy, girthy enough to stand its ground and hold the flow of spunk and piss inside the ballooned female as she pulled out. Helena winced in protest for just about one second before she hissed and shut her mouth with one hand, feeling the heavy flow of more piss on her scales instead of feeling it bloat her even more. Andrea was gone from the office for but a minute, but that was already too much for Helena and when she was back, the twin squealed in happiness and turned around to present her gaping maw to her. Seconds later the cock that had just been buried in her tailhole spread the taste of seed, piss and her own bowels on her tongue and pushed down her throat, plunging down her stomach again. Helena slathered the thick base in saliva, cleaning it as best as she could before the reflow from yet another load of spunk made her far too full stomach reject the several gallons she wanted so desperately to drink. Andrea knew that by this point she had to let her relax and digest a little, but that didn't mean that she wouldn't have to keep her cock sheathed inside of her throat for just a little bit more and so Helena found herself strapped to it. The musky and salty flesh spread a flavour so strong that it became her whole world, for those few minutes, only the cock that made the throat bulge out and forced her to breathe through her nostrils mattered, nothing else could get past that taste or smell. Her tongue danced as best as it could on her sister's flesh, making it glisten in yet another layer of fluids, cleaning it from spunk or piss alike, or even the remnants of her own vent on it. Andrea allowed her to do as she wished, shivering when the long tongue prodded at the inside of her slit once again and making her wonder if she could take one or two more loads down her gullet but she decided against it and pulled out, letting her cock flop on her back before feeling a few weak spurts land on those green scales.

"Are you alright?" She got a murr and some jumbled words as response as Helena shoved her snout under the base of her shaft and huffed loudly at the musky and sweaty air that pooled under her. She tapped her head to get some attention. "Can you walk?"

"I can try..."

"Good because I need some water and I don't feel like walking dear." Andrea smirked so hard that Helena shivered and did her best not to jump on her cock again: there was something in her that felt an absurd amount of joy when she got filled to the point of immobility but another part proved just as much pleasure in going around so heavy and sloshing that each step was a chore. "Get moving dear." And every part of her loved when Andrea acted like that with her.

Helena moved from under the table and hoisted herself on her feet with no little amount of effort, her form so heavy and so round with seed and piss that she huffed and had to take a break only after standing up. Her vent ached to be filled even more and her guts screamed to be emptied and filled again over and over, but she wasn't allowed to get the sweet release from the several dozens of gallons sloshing through her. With slow and carful steps, squeezing her belly through the door and walked to the kitchen to get that pesky glass of water that Andrea could easily get herself in less than half the time she needed just to make that short trip. Her stomach wobbled so much it stretched her skin even further and made her huge breasts bounce on the expanded dome and threatened to snap but somehow she was holding on and she wanted more still. If Andrea could produce endless amounts of spunk with little to no effort, she could take it with pleasure and sometimes but her sister hard at work to satisfy her. It seemed as if them being together like this, twins, lovers, seeking each other day and night, was sanctioned by the heavens themselves, with one complementing the other so perfectly no one else could. She wished to be able to bear her eggs one day but for now she just enjoyed the feeling of being used as a toy day in and out.

With her heavy gait and heavier paunch, Helena made her way back to the office and gave her sister the glass of water. Andrea kissed her on the cheek and raised her tail high in the air and that made the pregnant looking lizard skip a heartbeat: the most tantalizing of treats had just been bared for her to take and she wasn't going to miss on it. If Andrea did that, it meant that she was willing to bottom for once but she would not take that kind of chance, not today at least, her belly would make any humping pretty much impossible as her diameter had long since exceeded the length of her own cock. She knelt, or rather, laid on her stomach as if it was a pillow, the sized matched after all, and shoved her snout right under her sister's tail, nostrils pressed against the soft rim of flesh that contracted with her every lick. The taste of sweat, the earthy tones and even more concentrated musk made her head swim in pleasure, each passage of her tongue a journey by itself, burning through her brain like wildfire. Andrea relaxed and let her sister give her the most passionate of rimjobs and went on about her work as per usual, feeling that wet tongue clean inch after inch of scales and leathery flesh until nothing was dry anymore and still she went on. Her cock was hard and dripping large globs of pre and seed on the floor and when Helena shoved her tongue as deep as she could inside that rim, she let herself go and the loud sounds of seed splattering on the opposite wall echoed in the room, pooling with Helena's previous loads and overshadowing them with ease with every second that went on. There was a reason why her projects and the papers were all put behind a thick and waterproof glass frame, as everything else of value in the house, since the floor was more than covered in a growing layer of spunk that flowed down the drains on the edges of the room.

It was rare for the two of them to be able to unwind like this and Andrea was going to make the most out of it in the next few days but for now, she was content with unloading dozens of gallons on the floor. A waste sure, but with such an eager tongue plunged right in her tailhole, what more could she ask from her sister? Each shot was lost in that pool and by the time she was done with her work, the drains had been struggling to take away the ever thickening seed she produced and Helena was little more than a mess of huffs, grunts and spasming muscles. Her musk was something of a drug and too much of it tended to cause such problems, though Andrea hardly considered them problems at all.

Andrea got on her feet, stretching her legs after what felt like an eternity spend sitting down and groaned with the accumulated fatigue of roughly five hours of hard work designing the top floor of the newest building in the city, something that promised to bring a whole lot of cash home. In getting up though she deprived Helena of her treat and the dazed and musk-drunk lizard protested loudly for her sister to sit on her face immediately.

"Don't you think it's about time we had lunch? I'm starving here." Andrea asked but the answer she got was only a burb that stank of cum straight from Helena's stomach. "I guess I'll be the one eating..."

Andrea helped her sister getting up, a far harder task now that she was both heavy with what felt and looked like a healthy hundred gallons of spunk sealed inside her by those toys and so muddled with her musky ass that it was difficult for her just to stand in place and not fall on her own ass. Luckily the couch was not too far and she sat down immediately, taking a good breath while Andrea took the grates from the drain system out to allow a better flow from the flooded office and went about cooking herself lunch. Naked and with her cock out was not the best way to cook but she liked being free and in the nature in her own house, it made her feel so perfect and it was far easier to clean and play around when no one had to undress and worry about clothes or make-up. It was merely a matter of what went where and how much she could last before either one called quits. At the moment she was tired and her shaft ached a little, but she knew that it wasn't to ask for a pause, rather, her body was telling her that it could do so much more and despite cumming so much, she still wanted more, just as Helena wanted to be filled more. It was something of a vicious cycle and a welcome one.

With her meal ready, Andrea sat on the couch and Helena was fast to jump on her as she ate, suckling on her cock to draw more seed from its length and clean it up some more but her sister reached for her vent plug and pulled it out, forcing her to shove that cock inside to keep it full and not waste all that seed she had been granted. Andrea smiled and relaxed, now that her shaft was once more snugly secured inside her sister and humped softly, keeping her on the edge. Once she was done eating, her hands reached for Helena's smaller cock and stroked it, long teasing pumps, slickening the shaft with its copious pre, keeping it hard and throbbing. Helena shivered and tried to hold herself, but with her vent so wide and with her sister's cock slowly pumping into her very chambers, she didn't last long and soon her seed splattered on the couch in thick ropes, long hard spurts that travelled through the air and some landed several feet away from the tip. It was to be said that for a herm, Helena was already on the more heavyweight side, capable of outlasting most men with ease, but put next to Andrea and so devoted to being her toy, she didn't realize how virile she herself was and one couldn't blame her.

Her twin was outright ridiculous in every aspect but that was why she was the perfect match for such a monster. When they were young, Helena was the one between the two of them that brought home tails and horny teens, whereas Andrea was rejected and made fun of. She never wondered why until they first decided to bare themselves to each other: it was just one day when they had no clothes after a particularly bad rain turned them both into a shivering mess and while they waited for the dryer to do its magic, Andrea happened to wander around naked. Somehow, against her own will, she saw her sister just as naked and she liked how she looked, the way her bigger breasts bounced with every step, her wider hips making her sway so hypnotic. Her instinct didn't care they were blood related: she needed to mate with her till both dropped from exhaustion and her erection had been so painful she ran to her room and tried her best to relieve herself, not before Helena saw it all. It was on the third time such a thing happened that Helena 'happened' to be naked in the house that she couldn't resist anymore and things started going downhill so fast neither realized what had happened until they woke up covered in dried spunk and in Andrea's bed. Helena was so sore and full, shocked and... happy, satisfied. She liked the feeling of her sister spreading her vent so wide it almost hurt, she wanted more, and more she got. Day by day, they became more intimate until, well, until not being fucked silly by that monster cock wasn't on the daily menu and not sleeping together, tied, and full, wasn't a thing anymore.

"Are you alright Hel? You're not too full I hope."

"Oh, if anything, I'm not full enough sis, you know me." Helena smiled and kissed her sister on the cheek. "And I hope you're not dry yet, it'd be a shame if you happened to not have anything more to give me..." The lizard shot a glance to her sister and before she could challenge her again, she felt that massive shaft lodged inside her pump shot after shot of seed straight into her womb, adding to the already hefty load she carried. Her belly bloated some more, a few inches until it reached a good four and a half feet In diameter, more than what she got to experience in the past few weeks of work. "Mmmh, I knew that you couldn't be done just yet."

"But you had to ask anyways, right?"

"Yes, of course." Helena giggled and slumped on her side but kept her hips connected to Andrea's and her cock safely tucked inside her vent, still pumping gallons every now and then. "Can I ask one thing?"

"Go ahead, you deserved it." Andrea grunted softly and dumped yet another load with the countless others, relishing in the feeling of an overly full womb to rest in and all her warm seed sloshing around, momentarily halting her sister's speech as she too concentrated on the pumps of cum.

"How about we take a special bath?" Andrea's eyebrows cocked in surprise. "Please? It's been so long since we did something like that."

"A special bath? You really want me to go all out today, don't you? Is that why you blew me this morning? So that I could be ready and hard for the bath?" Andrea stared into her sister's eyes and the coy and devious look she got told her a lot about Helena's intentions but she didn't mind being used like that from time to time. She impaled her every single day, it was just fair that her sister got to attempt to wring her dry in the meantime. "Sure, I could go for a messy bath right now."

"Yay!!" The two kissed deeply for long moments before Helena got up and plugged her vent in the exact moment as Andrea's cock slipped out, but she failed to time it perfectly and a small gush of spunk hit the couch and the lizard still on it, coating her in a layer of spunk of her own making. "Opsie."

Helena rushed to the bathroom, which in her case meant that she waddled a little bit faster than before, a feat to recognise as she was a couple dozen gallons heavier now. Andrea and slumped on the overly stained couch, letting her body prepare itself for what was coming in but a few minutes while her sister made her way to the bathroom and prepped it for their special bath. It was such a rare treat that she couldn't help but feel overly excited and her very being showed it with unmistakable clarity: if her production was something to behold and fear before, with the prospect of being able to go truly all out, every fibre of her body, every muscle, moved together to pump out even more. Her cock sprayed seed constantly, pushed out by the sheer amount that was forming inside of her, pulses of pure virile matter, so thick they made Andrea wince in pleasure as each wad splattered on the wall and stuck to it with ease. It was a constant flow, shot after shot of seed, endless already and growing to insane proportion still, just to accommodate her sister's wild hunger and her most basic desires. Andrea's cock was so hard it almost hurt and one slight touch made her breathless by how good it felt and made her watch in a rare kind of amazement as it spewed forth a veritable river of spunk. One touch.

She stood up shaking like a leaf, the mere act of walking and feeling her shaft wobble under its own weight proved to be too much for her to handle and she had to force herself to walk with that slab of meat splattering its far too dense cargo all over the place. Helena was sitting inside the extra-large tub they had gotten after buying the flat, the second biggest object after their bed: it was wide enough to accommodate Helena's form with ease, including her massive belly and a couple extra people as well and it was deep. They had taken the old bathroom and turned it into a makeshift indoor pool with a toilet and some cabinets so that they could bathe together and not worry about size. Andrea hopped in and crawled carefully towards her sister, slow movement that still sent shivers down her spine, each small throb of her cock spraying gushes of seed that hit Helena and coated her front in white cum. Her mouth opened and she caught a few blasts, swallowing that precious loads with bliss as her body screamed to be filled with it and amped her own production in kind. The two embraced each other so tightly neither could take the stimulation for more than a couple of seconds and blew their loads at the same time: Helena's shots were instantly lost in the shower that was Andrea's massive climax, which made her previous orgasms look like water compared to this one. Each pump of that titanic length send gallons straight up, hitting the ceiling and splattering in a white warm rain, covering the two in a mix of fluids and lust, each one lasting several seconds and lengthening with every minute that went by. Once the bottom of the tub was full, Andrea smiled and, with careful movements, speared herself on Helena's cock, immediately feeling her seed fill her chamber and begin to make her swell. Her sister squealed and began thrusting in and out with her every muscle, turning that dominant lizard into an equally squealing and cumming mess that she loved being. The two's orgasm never seemed to end, or rather, each one was so close to the other that it was impossible to tell them apart, merely going from one to the next, shot after shot, filling the tub a little more. Barely five minutes later the tub was overflowing and the waves made large amounts of spunk fall out of the edges and the lost gallons were immediately replaced by more and more, until the bathroom itself began to fill and the floor was lost in a new sea of cum. The twins swam in it, still rutting madly, switching positions every few minutes, taking turns on top of each other.

Some time down the line, Helena decided to deepthroat her sister's cock once again and the insane flow made her so big and so full that the plug gave in and the contents of her bowels were expelled into the tub, gallon after gallon, replaced by a thicker wave that was lost as well. The air was so thickly laden with pheromones and musk that the neighbours noticed it despite the walls and the ventilation systems. The crack of the bathroom door was a sign that the two had long since given up on any sort of restraint and went truly and completely all out in their lust, flooding not just one room but the entire house just by themselves. Andrea held on to her sanity at the best of her abilities, going from one position to the other, from fucking to being fucked in a white heaven made of her overpowering scent and taste. Both her and Helena's stomachs were full of her seed and their vents were constantly being filled and drained, stretched and gaping while their cocks ached and remained perpetually hard. The sea of cum in the house reached five inches deep and by that point, neither lizard was able to think straight anymore and laid on top of each other, their vents connected by their shafts, leaking gallons of seed every second, adding them to the tub that in turn let them flow out. The house was ruined, completely, much more than the last time they had done this and an eerie sense of pride washed over them before they passed out.
