* Echoen smiles prettily. "I wondered where you'd snuck off to."

* Avylin pets your hip with her free hand. "Off to my fortress of solitude."

* Echoen breathes in lushly, that hip pushing out into your fingers. Change of stance, or a widening? Not entirely clear at the moment. "It's wonderful to have you back, be it briefly or more often." Shi coos, kissing you.

* Avylin mms at the smooch, returning it with a brief, but warm kiss on the lips. "You do seem quite happy to see me! Not that I'm complaining." That wandering paw slides back, around that nearing- or widening- hip to stroke alon gyour backside before returning.

* Echoen exhales pleasantly, tipping forward to learn more against you. "You should complain more." Shi rumbles, hir breasts threatening to engulf your own chest. Oh, yea, shi's widening. You can /feel/ the slow nudging growth against you. "You make such cute squeaks when you're huffy~"

* Avylin hrmphs a bit at the increasing pressure against her, taking off guard briefly, nearly stumbling; she recovers with a push up against you, though, her body tensing, muscles flexing... and as they do, her body surges slightly, not just pushing against yours but swelling. It's not an exagerated growth, but it's widespread... her hips growing wider, thighs growing thicker, shoulders and chest broadening, height pushing upward. She braces both hands against your hips and smiles crookedly at you as she wrestles her chest to yours and leans in to nuzzle your cheek. "Hrmph. When do I get huffy?"

* Echoen giggles, the act of hir titter causing a brief but noticible surge in hir size, hir breasts spilling overtop your own. Shi doesn't quite let you stumble away from hir - not going to let you off that easily - curling hir hands across your waist to tuck you to hir broadening, thickening, growing batty bulk. The sensation of your growth is a delight to hir, encouraging some alternative swelling. Shi noses down at your soft and slender batty muzz. "Oh, you've plenty to complain about. "Echoen, you're not big enough" "Echoen, you're not filling all my holes" "Echoen, you're too loose." "Echoen, service me /and/ me over there, not just one!" So on. And so forth." Shi grins, fingers squeezing into your plush bottom. "Including when I fill you up so much you have to stretch to fit."
* Echoen seems to gain a bit of inspiration suddenly, right when you're mid-sentenced. Dipping both of hir paws under your tail, between your thighs, hir fingers push lewdly across your tailstar and sex - and shi pulls, firmly but not roughly, both to one side. Your flesh and bones stretch and widen, new flesh springing into being immediately, as shi pulls your hips apart. Now, connected at the belly, are two broad battyhips, each with a set of legs, a sheath, everything, your stance now four-legs wide.

* Avylin duels her muzzle with yours, sliding past to score a kiss on your cheek, then drawing back to smooch your lips, quick and warm pecks. "Mmh! Not my fault. I'm a girl with needs, you know? They just happen to, y'know..." SHe trails off a bit as she adjusts her footing against you; her chest swells wider, pushing underneath your own to nudge against your body, pressing your own bosom higher in the process, likely to the inconvenience of us both. Her figure grows more lush and exagerated, more so in some places than in others- and then you go and split her down below like that. 
Avylin: SHe stiffens and gasps with surprise, squeezing her eyes shut, delighting in the sudden intensity of the delightfully sudden change... plush thighs taking shape, new legs stretching out. Her twin sheaths surge with delight as they're completed, the entrance to one spilling open as a broad battycock unspools from within, the other following suit soon after. "Nnhh! And you certainly aren't helping!" She adjusts her extra-wide stance a bit, turning her twinned hips inward in a V-shape, leaving you caught between both pairs as her legs rub warmly to your own.

* Echoen 's first two fingers are curled under your thighs and buttox, slipped into your silk-slippery sexes, and hir palms are full of your jiggly white-furred rumpflesh. Shi continues to grow with you, hir sheath pushed between the valley that your twin sheaths make between them, the tip of hir chocolate-fleshed cock burrowed between your tits and hirs. "There we go~" Shi coos, breathing down your neck, molesting your gorgeous lower bodies as they continue to grow unabated. "The squeaks of surprise, indignance. No better than from a batty."
Echoen:  Hir legs become straddled by both of your hips, your shafts pushing up to bump the underside of each of hir tits. Pushing hir hips forward, hir cock *pops* between both of your hips, arching up along your spines where they merge into one. Removing hir fingers from your sexes, shi grabs hir cock - and pulls it in both directions, moaning breathily into your face as shi splits hirself, though not as far as you. A single third leg pushes out to rest on the floor, hir shaft splitting into two, one left and one right. Slipping them between each pair of your thighs, shi stuffs each cock into your sex like one would rudely burrow a horsecock dildo into a girlfriend's vag. 

* Avylin 's four feet shift and shuffle to accomodate all your splitting down below- she thinks she can see where this is going, and not only is she not surprised, she hikes her thighs and shifts her weight to better accomodate you as you move to stuff her waiting sexes with your newly-doubled endowments. Of course, the anticipation doesn't lessen the delight any- such that as you drive yourself up and into her split body, her spine arches back and her muscles stiffen, a shuddering gasp of pleasure escaping her muzzle. Her legs push her up onto her toes, her chest smooshes more fully against yours, and the hands on your hip lift to your shoulders intead- 
Avylin: it's precarious, balancing a bat of such generous proportions against yourself like that, but she does her part, twin rumps flexing as her feet shift and adjust to keep her perched there against you and against the increasingly heavy bulk of a body that swells yet taller, pushing well past ten feet of hourglass-figured bat. The shudder of pleasure culminates in an upward tip of her muzzle, ears slicking back- and as she moans with pleasure, her muzzle widens and splits, a smooth cleft driving down the center of her face as her head pulls to either side into a pair of the same. 
Avylin: Both heads then dip down to snag your muzzle in a heated kiss- and your lips tingle where they meet hers, moments before a similar divide rushes up your nose and muzzle, between your eyes, continuing down to the base of your neck as you soon find yourself as delightfully double-headed as herself. One of her muzzles releases yours, leaving the other to keep its counterpart locked in a kiss as she grins to you. "And here I thought you'd done enough to contribute to batty overpopulation, lately..." Her twin tunnels quiver and squeeze around your members as if to puncuate her tease.

* Echoen 's cocktips kiss together in your overly large womb, grinding together as shi thrusts rythmically into you. Your pussies filled up and stretched snugly around hir shafts, shi keeps hirself very large - even if you grow larger to accomodate hir size, shi merely hypers hirself further, to provide the proper stuffing, big enough to have you complain through involuntary squeaks each time shi plows upwards. Shi's 13 feet tall to your 10, hir testes slapping against your thighs, as large as medicine balls. Proper, on a frame like hirs. Two tongues slide from hir single muzzle to entwine with both of your tongues, doing hir best to share a three-way kiss with you, and enjoy the buzzing tingle of your tainted touch. 
Echoen: Breaking the kiss to cry out, one voice becoming two, then one again as a muzzle is silenced, trapped with one of yours. "Never... enough." Shi huffs, wrapping hir arms around your single upper waist. Your spine tingles, centered on the point where one splits into two - a third spine pushing out from there, into a third set of broad white batty hips and long legs. The sheath it has, however, is broadly stuffed with too much cock, far too much, four strawberry-pink cocks spilling out and spilling seed as they go, fueled by eight obscene testes, two four-stuffed sacs jiggling side by side on either side of hir third leg. 
Echoen: All four cocks push underneath hir own legs and thighs, drilling up to burrow into hir own twin cunnies and tailstars. Hir third leg is trapped between your thighs, sheath and sacs, hir knee touching your belly. An increasingly gravid belly, as twin gouts of seed flood your womb. 

* Avylin 's twin heads both bite their lower lips as they draw back, ears slicked back and eyes squeezed tightly shut; this latest surge of growth sends a wave of pleasure through her body so intensely it's all but paralyzing, leaving her clutching against your larger frame, wings curling up around your shoulders, hugging her against you. It's a tall order, too, forcing her fingers to dig into the mucles of your shoulders, so much between us threatening to push her broad body away from yours- the twin bosoms jostling for space, the surging tummy of hers pushing against your own as it fills out. 
Avylin: Luckily, there's lots to keep her tangled against you... namely, the twin shafts buried deep inside her body, of such girth to practically knot you to her even if there's no knots to tie. So, too, do her own middle members, splayed in pairs to either side and between your three thighs, keep her fastened in an erotic fashion, stretching your four entrances snugly about their strawberry girth, even as sticky surges of fertile cream pump upward into your body. Her other two members, layed out from her outer sheaths like a pair of cannons, splay to either side of your outermost hips, sending ropes of seed into the open air behind you. 
Avylin: Eventually her gasp calms, though her breath remains shallow and shakey, while her muzzles bump and nose against yours. Her body remains tense, flexing, tightening around you, a constant churn of seed erupting inside your body. Her belly is filling all available space between you and herself- the bulging outer curves of it pushing to the side, skin stretched around the bulk of seed being pumped into her fertile depths. Thick surges of it escape her middle sex, but not enough to diminish the load you're leaving in her.

* Echoen has hardly finished hir tainted twisting of your body, altering parts of you that shi's not even touching or paying much attention to, other than glancing. Your ears, for example. Such lovely lengthy whitebatty features, why aren't there more of them? Each of your ears gains a second ear just behind it, every flick or twist touching each other sensually. Shi trills out sweetly as your sexes clench tightly to hir shafts, coaxing each pumping, surging flow of spunk to burrow into your belly and breed you. For all shi floods you, your four shafts fill hir much faster, both into hir womb and into hir guts to nourish hir. 
Echoen: Hands - of course shi's going to grow more pairs of paws to touch you - caress each of your outer shafts, fondling up and down and across them, many fingers and palms sliding and stroking to make the utmost mess of us. Your rotund tummy is nudged against hir own, pregnant bellies bumping and sliding to each other by virtue of lack of space. The gooey splatters of cum that pour forth from your middle sex feel different with each gush, a little more... clogged, each time. 
Echoen: This middleset of rumpcheeks and hips swell larger than all the rest, birthing hips by definition, fleshy and pliant to accomodate the kits immiently spilling forth. Intent on joining us together even further, the big brown batty twists us in another way - between your necks, your white fur parts to a blossoming pink sex. Between hir necks, a huge dark sheath forms, with balls pushing against hir necks. It's oriented upside-down... and the decidedly equine cock that erupts forth, fits itself down your neckpussy, our undulating bodies providing the thrust.

* Avylin 's faces remain locked in expressions of intense, ongoing delighty, as such a perpetual climax like this may produce- breathing in low, shuddering gasps, fighting for each gulp of air between the electric surges that work through a delightfully mutated body tuned more and more for breeding by the moment. The warm channel of flesh working down between her necks quivers and clenches around your newly-formed member, milking it, then clenching tight with the same orgasm that envelopes the rest of her and drawing your seed- for soon that equine neckshaft of yours is surging with the same payload that the rest of your members are- down into the common womb that her body now bears many channels to. 
Avylin: Her hands run through the fur of your shoulders, then slide downwards... no, not that. THey've split into two pairs, one remaining up as a second pair of wings pulls away from the first to hook around your middle. That lower pair again splits, its downward sweep reversing as a third pair of hands draws inward, moving to cup your chest... and heft your bosom against her own in a quivering grip. With a bit of adjustment her chest jostles with yours until her plump teats play against your own... then yield beneath them... then part as your nipples stretch out into thick members, their broad crowns- equine like your neck-shaft- delving into the warm cunnies that her own teats form into. 
Avylin: The twin penetrations send another surge of delight through the bat, drawing a gasp from each muzzle, before her hips tighten and her toes curl. Her abdomen swells beneath her gravid tummy, the folds of her middle sex bulge and part, before the head of a mottle white-and-brown bat kit pushes past. She's young to look at, deceptively small, but rapidly maturing, such that even as she spills from her mother's womb, 
Avylin: her features broaden and fill out, muzzle lengthening, ears growing from small and round to large and pointed, chest and hips filling out with feminine charms as strong as the proud erection between her thighs is masculine. She stretches and churrs with pleasure, before turning about and reaching up to aid the two sisters hot on her heels from the womb, welcoming them into an eager embrace.

* Echoen has six pairs of paws hirself, and will likely need more - though you notice that each arm is split at the elbow into two more paws, and each paw is split at the wrist into two hands. The effect is so much touching, holding, caressing, gripping and pulling. Kneading your nipples, massaging your balls, caressing your cocks all over. Fingers explore your pussies on your chest, until hir nipplecocks swell to meet them, plump furry sacs kissing between each heavy tit.  Entwined and entangled, our transformations are no-where near complete. Hir thighs soften around your burrowing shafts, swelling thick and broad, then 'stepping' backwards into a second set of hips and legs... providing hir the space for hir new pussies to pour excess fluids, already hir brood crawling down hir channels. 
Echoen: The creamy-chocolate batties that spill from your sex open their eyes as they emerge from you, stretching your cunny widely around their shoulders and hips, hands taking hold of many parts of their sisters in order to pull themselves out of you. One girl lands daintily on her feet, smiling at her sister, prominently displaying her budding chest and swelling shafts, then turning to aid her sibling in tugging forth the next, and the next.
Echoen:  Another girl has long, flowing hair that spills down to her waist, and she walks about the an exhulting smile, practicing her sashay. By the 5th kit's birth, Echoen has begun to add hir litter to the bunch, the first kit trotting over like a cat, one forepaw in front of the other. Her curvy, plump body jostles with every step, chests bouncing, her heavy sheath swinging between her hind legs. They meet and greet with each other, all growing as large as normal adults, milling about between the many legs of their 15-foot tall white battymomma, and 19-foot tall chocolate battymomma. 

* Avylin remains tense and groaning for several long moments- and maybe she's squeaking a bit, too, just for your indulgent pleasure- but gradually she seems to be mastering herself. In a change much more subtle than the others that have been brought to bear upon her, she adapts to the constant surges of delight, the tingling ecstasy surging through a body caught in a continuous loop between birth and release. It lets her blink her eyes open and look to you, first with a dazed expression, then increasing clarity, and eyes that gleam with lust and affection. Still panting softly, she brushes a few kisses along your muzzles and cheeks, then manages a loose grin. 
Avylin: The hands that stroke along your curves- at least, the outer curves, the ones she can reach- smooth out your chocolatey fur, then dig into scritch into it. The four shafts buried up inside your body continue to pump out ropes of seed, but at a more moderate pace, while her own sexes- two between her outermost pairs of legs, two in the midst of her plush breasts, and a fifth down the middle of her body- maintain a snug, churning tightness, as if milking your own members. And of course, she continues to add to the growing litter that surrounds us, her back arched and middlemost, broadest hips thrust backwards as the line of vanilla-chocolate batkits continues. 
Avylin: The seventh daughter seems fairly typical until the length of a 'taur's hindquarters follows her frontmost pair of hips past the womb; the eight and ninth appear to be spilling together from her mother's womb until it's revealed that this latest daughter simply has two heads like her mothers both do. Even as the next kit pushes forward, the white bat's middle hips grow a bit wider, soft bulges pushing out beside her stretched sex, then parting into two more- soon giving her three channels through which to birth what is still just the beginning of a promising litter.
Avylin:  It elicits another shudder of delight from her, and she smiles against your muzzle with both heads, before leaning up to give your noses a pair of soft kisses, then suckle softly. As she does, you feel them pushing outward, then tingling with sensitive delight, as they stretch outward into erect batty cocks, slung like cannons from the top of your twin muzzles. Your ersatz mate grins around them as she moves to tangle your newly-grown nosecocks with her slender tongues and slowly work them with a lazy slurp.

* Echoen is a musk-seeping behemoth of multibatty, but shi seems well adapted to the incomprehensible pleasures that wrack hir body, able to think and plan - if only just, and probably not while in the throws of a particularly firm orgasm.  Shi sees your intellect coming 'round, encouraging it with soft strokes of hir fingers through your cheekfur. "Ah~" Shi croons, as your hips plow forward to nudge your quad of cocks deeper within hir tunnels, elicting a tense clench from all of them. Together we work a rythm, a pattern, a swirling churn of rocking bodies, clenching muscles, and endlessly spilling shafts. Coordinating becomes easier, and every growth and addition is met with its appropriate counterpart.
Echoen:  Failing that, one or more of our growing litter rises, literally, to the task, their sole purpose becoming willing tools of pleasure. Each sister always finds many open wings and hands and smiling faces, proffered breasts and welcoming cocks and cunnies, to help them into the world, nourished and nurtered in the critical first few moments of life, until they can properly join the swarm. Echoen settles into a pattern of birth, electing for a regular overwhelming surge of pleasure and joy of birthing several at once, as opposed to your constant application of pleasure from birthing one after another after another. 
Echoen: Clustered around us, space is becoming a luxury, so kits begin to spill forth from doorways, into other rooms or outside, carefully keeping the construction of the house intact, or at least, in a way that can be reassembled later. The colony disseminates through the suburban neighborhood, only returning to bring food, news, or to bear their own children with the blessing of their titanic parents. Each kit delivers its own unique bloodline, taking most species traits from their mates, but keeping constant with body configurations. 
Echoen: Echoen and Avylin have between them the endless task of producing every possible configuration of batty, while they themselves enjoy twisting and changing each other in a plethora of blissful ways. The last glimpse we see of them, is of two long tauric bodies pressed flank-to-flank, hip-to-hip, two of many... sexes spreading wide as immense taurs step out, holding hands as soon as they can reach each other, ensuring that any lucky would-be mate will be forever bound to an incestual threesome.
