The soft rustle of the sheets melded seamlessly with the long, slow hisses coming from the bed's occupant, the sibilant noise interrupted only occasionally by a slightly frustrated groan or a telling squelch. And if one was close enough (or lucky enough to be close enough) they would hear the faint buzzing coming from the serpentine female's abdomen, barely audible now that all but an inch of the battery-powered toy was buried in her slit.
               Jane Reid was working herself up towards her second climax, knowing that one wouldn't be enough. Her last night had proven restless albeit pleasant as her dreams unerringly drifted back to a clandestine encounter at the school she worked at. She had a good memory and it served to render every detail of the handsome young colt who'd provided her with a little sample, even if he did make her earn it.
               Even though she'd gone farther than professional ethic would allow, she still wondered what it would have been like if she'd gone further, and her dreaming mind conjured up titillating simulations. With her slitted eyes closed she pretended that the toy she was pumping in and out of her drenched sex was in fact Adam's prodigious shaft, even though she knew that the buzzing phallus clasped in her womanhood paled in comparison to the real thing.
               But the real thing was out of the question. She had little doubt that Adam would be all too happy to come in for another little 'check-up' but she was hesitant to call. While it had provided some valuable data, the colt's specimen (that is to say the part of it that didn't wind up sprayed down her long neck) provided no clue to the mystery behind the young horse's success with females. And without knowing that, Jane was reluctant to become just another besotted conquest for the young stud.
               She felt her hand cramping, even though at this point she was mostly just holding her vibe in and bucking her hips up and down, the whipcord musculature of her body flexing as she worked herself towards blissful release. And when even that failed to get her past her peek, she decided to up the ante a little. She kept the buzzing toy within her as she scooted along her bed until her back was against her pillows.
She was flexible even for a snake, and the sheer length of her serpentine neck meant it was a simple enough matter to bring her scaled muzzle to bear on the splayed folds, the tiny scales covering them glistening with the juices her thrusting and bucking had pumped out of her honeypot. Even though it wasn't what she was in the mood for right now, she didn't mind the taste of herself, or for that matter other females.
She kept the toy buried as deep as it would go as she flicked out her forked tongue, playfully lashing the well-stuffed slit at first and feeling her insides tense up as the twin tips of her appendage flicked along the tiny scales. She couldn't help but smile at the memory of her first mammalian lovers and how surprised they were to find her so responsive to tactile stimulation. They assumed that scales would be like some sort of armor plating that dulled the sense of touch, but the truth was that most of Jane's body was as sensitive as a mammal's palm, and some of them were more responsive by far.
This was why even the lightest flick of her tongue against the impossibly fine scales covering her sex was enough to make the long tail whip around across the bed sheets, and also why the boob-job she'd given Adam had been almost as stimulating for her as it had been for the colt. The memory of it was enough to send her free hand shooting up to palm one of her firm globes. Like all snakes her nipples were inverted, but it only took a few rubs against the little patch of bare skin to make the nub stiffen and poke out. Without any scales covering it, the tiny protrusion - along with its twin - was one of the most sensitive parts of her body, second only to the other little nub her tongue was even now brushing against. One of the reasons they needed to be hidden away until they were needed, and one of the reasons that snakes never breast-fed their young in public. The noises the mother made while her child nursed would be too hard to explain to members of other species.
And with cobras such as Jane, the noises were only one give-away that someone was having the sort of fun one shouldn't have in public. Her hood had fanned out the moment she'd started licking herself, a bit of a waste when there was no one around to see the markings covering it. She thought of it as one of her best features, and it always tended to amaze someone who'd never been intimate with a member of her own species. And if I tilt my head down at just the right angle, it looks like a heart!
She kept the hand gripping the base of her vibrating toy still, choosing instead to buck her hips against it as the tips of her forked tongue served to flick and stroke the folds splayed around the thick shaft. She could feel her climax build to the point that she didn't need to imagine some male and instead just focused on the physical sensations. She sighed and hissed even as her body writhed on the bed until she finally caught sight of her straining sex clenching around the buzzing toy. The tension in her muscles broke as the desperate need was sated and the buzzing of the buried toy became inaudible over her own noises.
Not a spectacular climax, but one she felt would let her get some rest. She twisted the base of her vibrator until the buzzing inside her died down and she pulled the plastic cock from her dripping sex. Exhaustion came quickly on the heels of her orgasm, especially considering how late it was, but the sight of the pale-pink length dripping her nectar as it slipped from her still parted lips made her get up. The years spent earning her medical degree had conditioned her to high standards of hygiene and cleanliness, too much for her to get a decent rest knowing that both her battery-operated friend and her crotch were soaked in her juices...
*******
"Yes, I know it stings, but if you don't hold still it will only take longer." Jane spoke patiently to the rat seated on her exam table. "You're lucky, you know that? All those fights you keep getting into and this is the first time you got sent to the nurse's office..." she chided.
She knew the rat wasn't really a bad kid though, but she'd heard some of the teacher's complaining about him. Mostly the remarks were about his appearance and thus went ignored by the cobra. She'd gone through her own rebellious faze, and nobody meeting the dedicated young medical professional would have guessed that there was a time when she's painted her scales, had piercings in the rim of her hood and wore clothes so torn and ripped that they looked like they'd been pulled from a wood chipper. And some of those tears had been in very interesting places...
And while the need to rebel hadn't changed, fashion had. Studded leather had been common in her day, but her crowd had preferred garish colors, unlike the black the young rat seemed fond of. Not very imaginative, but it did go nice with his grey fur. And the Goth look was probably why Jack got into so many fights.
"Will I need stitches?" he asked while Jane diligently ran a cotton swab over the cut.
"No. It's messy, but it's just a shallow cut. You'll just have a little line of bare skin for a while..."
"Well, women like scars, so..." he said, shrugging as best he could while keeping still. Jane couldn't help but roll her slitted eyes at his nonchalance, not failing to note that he'd said 'women' and not 'girls', but not thinking too much of it. At fourteen years old, you'd think girls would be enough for him...
"So, that's why you got into a fight? To get a girl to notice you?"
"No. I got into one because a girl noticed me."
"Care to explain that one?" the cobra asked, pushing the kid's dark bangs away from the shallow gash running just above his brow.
"Sandra Collister came up to me in the hallway and we started talking when Brent jumped me from behind." He said bitterly.
"Would that be Brent Walters?" she asked, thinking of a lynx a year older than jack. The boy was big for his age, and while not actively a bully he did like pushing around anyone smaller than himself who he thought was getting in his way.
"Yeah. He'd been drooling over Sandra for a while but she won't give him the time of day. So when he saw us together he thought I had been hitting on her and rushed me from behind."
"Well, while I don't approve of fighting, you can be proud you managed to hold your own against a boy his size."
"I wasn't holding my own. I was beating the crap out of the douchebag until the teachers pulled me off him!"
"Language!" she admonished on reflex, but couldn't keep the corners of her lips from lifting a little.
She rolled the name Sandra Collister around in her head until the vision of a pretty little fennec popped up. A girl walking up to a boy risked coming off as needy, but she supposed a boy like Jack was worth taking such a risk. And if she read her right, seeing the rat beat a bigger boy in a fight would do little to turn her off.
Although little Sandra might be barking up the wrong tree... she thought to herself as she pointedly try to ignore the way Jack was behaving with her. Working so close to his eye she couldn't help but notice it drop every now and again, and the effort it seemed to take for the boy to lift his gaze again.
She supposed it couldn't relay be avoided. Snakes were famously slinky, and Jane Reid had a body that was slender even by serpentine standards. That meant that a set of breasts that would have looked ample on any other female made her look decidedly busty, and with a waist a large male could wrap his hands around meant that finding a well-fitting uniform was tricky. As a consequence Jane wore one that hugged her slender waist but couldn't button all the way up, giving Jake plenty of reasons to look down as often as he could.
She knew she should reprimand him, but it was that time of the month for her when male attention felt nicer than usual. Even though the white fabric buttoned tight over her trim belly didn't betray anything, any reptile femme who'd ovulated at least once could tell when her body was working on an egg. The instinct to breed wasn't overwhelming, but it did make her look at males a little closer and sometimes a little longer.
Not that Jack had anything to worry about. The boy might have some interesting ambitions with his talk of women and the glances he stole of her scaled cleavage, but he didn't really have anything to offer. She had to admit that he was cute, especially with the dark and broody thing he had going, but cute could only do so much. It would take a few more years for puberty to work its magic on the boy and turn him into someone who could really give her what she needed.
"That should do it. Just try not to touch it in the next hour or so..." she said, straightening up and giving the boy another once over. The pants he wore had been ripped and slashed intentionally here and there and her sharp eyes caught sight of a little bit of blood-soaked fur. "Let me take a look at that knee..."
"That's just a scratch, there's no need to..." Jake said, and Jane couldn't help but notice the sight of her kneeling down to examine him seemed to have robbed him of some of his cool.
"Then I'll just clean it up quickly and send you on your... way." She said, recovering after glimpse at the boy's crotch.
Well, that explained why he'd suddenly become embarrassed at the thought of her looking around a little lower. Black fabric didn't really reveal all that much, but it still failed to hide a very sizable bulge as it stretched across the proof of just how much Jake had enjoyed his little stolen glances. And as she soaked a fresh swab in disinfectant, it was Jane who was having a hard time keeping her eyes from wandering.
Well, at least we know what Sandra was after when she approached him... she thought wryly, although the fennec girl was a little too ambitious. A girl would need a little more experience then she figured the vixen possessed before trying to tackle something of that size.
"There's nothing to be embarrassed about. Among boys your age that sort of thing can happen for no reason at all." She said, smiling a little at the way Jake had tensed when she'd addressed the elephant in the room. And then because she just couldn't help herself, she added: "Of course, looking down women's blouses doesn't help..." she finished, but was surprised when the remark failed to ruffle the boy's feathers. "You know, pulling a stunt like that is a good way to get yourself slapped across the muzzle..."
"So why didn't you?" the young rat asked, surprising the snake who was sure she'd embarrassed him into silence.
"Well, I'm under the Hippocratic oath." She replied in a less-than-serious tone. "Anyway, don't you think you should be saving those looks for all the girls that come running up to you in the hallways?"
"Why? I mean Sandra is nice and all but... I just find women more attractive..." he said, and the sheer honesty of his confession made the cobra grin.
"Hmm. You know that's a pretty big step you're skipping. Wanting a woman rather than a girl is one thing, but do you think you have anything a woman would want? After all, girls are easier to... impress." She said in a way that hinted that what she really meant was that they were easier to satisfy. "I guarantee you that any woman with the sort of looks that would catch the eye of a young man like yourself has had experiences that the aforementioned young man would find it impossible to measure up to."
"I'm not clueless you know. I've had girlfriends and we've ...done stuff. I just..."
"...never got that far?" Jane asked with a lilt in her voice that betrayed just how stimulating she found this little exchange.
"Not for lack of trying..." the rat replied and she responded with a little hiss that was her species' equivalent of a huff. He wasn't as brazen about what he wanted as a certain other boy who'd passed through her office recently, but he wasn't afraid to reach for forbidden fruit.
"You know..." she began, musing out loud in a slightly conspiratorial tone "...a woman could get into a lot of trouble over what you're suggesting."
"I can keep a secret." He said, and for some reason she couldn't quite explain, the cobra believed him.
"You'd have to make it worth the risk though. Think you could do that?" she said, rising with sinuous grace until she was leaning over him again, one hand pausing on the top button of her blouse.
She knew what she was doing wasn't the wisest course of action, but she felt that it might be a cure for her restless nights. Just what the doctor ordered she thought, even though it was self-prescribed therapy. Jack didn't have a response to that other than a nod, but she didn't really expect him to be able to come up with anything. For all his bravado and his endowments, he was still just a kid who was, in all honesty, over his head but willing to go a little deeper.
And while she doubted his brain had enough blood at this moment to string together a thought, hers was working just fine. The door was locked, as it was during every exam, and everyone apart from the young rat was in class. That meant that the hallways were empty, but more importantly tiled, just as her office was. That meant that as long as she kept at least part of her long tail resting on the floor, she'd be able to feel anyone walking towards her office long before even Jack's keen rodential ears picked it up.
With the decision made she popped the first button, her shirt opening wider as the young rat's eyes did the same. She made a point to slowly fan her hood, matching the pace of her fingers as they worked their way down. It took three more buttons for her impressive chest to bounce free, her nipples still hidden away but with the scaleless areolae clearly indicating where a curious young boy should look for them.
She quickly undid the rest and shrugged the blouse off, letting Jack feast his eyes on the expanse of cream-colored scales framed by the darker stretch that started along her sides and ran down her back. She unzipped her shirt and hooked her thumbs into the waistband, making a point to swing her flared hips as she shimmied out of it. A pair of panties the same shade of white as her uniform were all that remained, a delicate thing of sheer lace that hugged her firm curves. She turned around before removing those but teased the boy by keeping her tail down. Best not to overwhelm him anyway.
She'd considered asking him if he was still up for this after turning around, but the question was clearly unnecessary. The bulge in the rat's pants had been impressive earlier but looked positively painful now. Well, for starters I can kiss it and make it better she thought, but since the boy would be losing his virginity to her, she figured he owed him a memorable encounter, rather than a vigorous quickie.
With that in mind, it was his face she was bending down over, rather than his crotch. Her hood was fully fanned now, her tongue flicking out briefly to get an early taste of her young mate. When her lips finally met his, she was pleasantly surprised to feel his hand on the back of her long neck and his tongue slipping into her mouth to play with her own.
The boy hadn't been lying about his experience, and she had to admit he was quite a good kisser. A brave one too since many people were hesitant to French-kiss a venomous snake, even though her fangs were retractable and were even now safely tucked away. And it didn't take long for her to feel the boy's other hand as he brought it up to cup one of her ripe mounds, his touch confident at first but wavering for a second as he felt the weight of it against his palm. Bigger than what you're used to, huh Romeo?
She was a little hesitant to break their kiss since she did enjoy foreplay in general and Jack's reverent touch in particular. As she pulled her lips from his she gave the rat a playful flick of her forked tongue across his nose-pad, her smile ensuring him that she wasn't done with him by far. Her nimble fingers made quick work of his belt and fly, but when she finally freed his erection it was her turn to go wide-eyed.
During anatomy class Jane Reid had learned about many species, both inside and outside, and she knew that what she was looking (or to be honest - staring) at was a medical abnormality. The plump furred sack hanging under the swollen shaft was impressive, but she knew that rats tended to be quite heavy down there. The pink length sticking out of his sheath was smooth except for a subtle outline of a head near the top where the cobra's lips seemed to be drawn to.
"Let me know when you're close..." she hissed and after a nod from the boy she opened her mouth and descended eagerly along his manhood.
She couldn't help but smile around the rodential length in her mouth, savoring the way the boy's body tensed up, his hands clenching into fists as his pride and joy was swiftly and skillfully swallowed up. She doubted any of his girlfriends had managed to take this much of him considering that the blunt tip of his cock was even now pushing into her throat. 
She began to slide her mouth up and down her young lover's length, keeping alert for any signs, voluntary or otherwise, that she was pushing him too close to his edge. She was aware of her own sex beginning to drip as the taste of a virile male filled her mouth but caught her tail before the tip could work its way between her folds. Jack was showing admirable stamina so far, but it certainly wouldn't hurt to let herself get a little riled up before they moved on.
When she cupped his furry sack she was rewarded with a groan and a trickle of the boy's juices down her long throat. His pouch felt as heavy as it looked and she wondered when was the last time he'd gotten some relief. The realization that this boy was definitely old enough that he wasn't shooting blanks raised some other concerns. There were plenty of condoms in her office, of course, but she was hesitant to reach for them. Despite the fact that she knew for a certainty that she was fertile, the species gap was a big one. It wasn't unheard of for reptiles to successfully mate with mammals, but it usually took a couple a lot of trying to do so...
"If -ungh!- if you keep going I'm gonna..." Jack groaned, his alarm interrupting the cobra's thoughts as she quickly released his pouch and pulled her mouth off him, giving the now shiny shaft a quick flick of her forked tongue as a good-bye kiss. Well, a good-bye from her mouth, anyway...
"Off the exam table, and off with your clothes then. Let me get as good a look at you as you got of me..." she said, smiling as the boy's eyes remained glued to her form.
Once he got off the table she adjusted the height before hopping on, keeping her long legs parted and making disrobing more difficult for the rat who couldn't get his eyes off the glistening patch of scales between her legs. Or more likely the delicate slit lying in the middle of it. If she was going to make the boy wrap-up, this was the last chance to do it, but as she looked at her young lover with nothing but his leather and spikes on, she decided not to bother. It really was a slim chance, but more to the point Jack really was very handsome and very, well the professional in her would call it 'healthy looking'. If he did wind up giving her a hatchling, it was sure to be a beautiful child.
All the urging the rat had needed had been for Jane to part her thighs a little wider and give him a look even a virgin could read quite plainly. She leaned back a little and braced herself with her left arm while the other one sought out that impressive shaft bobbing between the young rodent's legs. She guided him to her slit and was quite touched when he waited for her permission before entering her.
It didn't take more than a little nod, but still it was quite gentlemanly of him. The size of him, on the other hand, was anything but. He started pushing it slowly at first, no doubt worried about the sight of her stretching around the cock that started twitching the moment it was wedged between her folds. A touching thought, but unnecessary, since a snake's sex was generally always quite snug but very... accommodating.
She let out a sight that ended in a hiss, hoping to encourage the boy and wondering briefly if it was just an act and he was teasing her intentionally. One look at his face dispelled the notion. She doubted he could think at this point, let alone scheme, his eyes wide as they wandered up and down her body. When they settled on her chest she reached out and pulled his head gently towards her scaly mounds, hissing again when he pushed himself all the way in once she had his muzzle buried between her serpentine tits.
"They're in there, if you're wondering..." she whispered in one of his ears, remembering the way he'd stared at the little patches of bare skin in the middle of each mound, and the little vertical lines where nipples should have been. "Can you get them to come out and play?" she asked with a little hiss that turned into a long one when his lips found one of her areolae.
The prudent thing to do would have been to keep her tail to the floor as an early warning system, but Jane wasn't in a prudent mood. The long limb moved on its own, slowly coiling around her lover as she took him in a uniquely serpentine embrace. The last thing the feral ancestor of the young rat would have wanted, but in this case it wasn't her tail that was doing the squeezing. 
The feeling of her silken walls tightening around her young lover every time he pulled out were heaven, as was the feeling of the boy thrusting back into her. She could feel the tension in his body as he fought the urge to just pump away until he came and was quite touched by how considerate he was. And she had to smile as she wondered if he knew just how close he was.
She had an easy time keeping quiet, or at least relatively so, but a little gentle suckling had teased her nipple out of its hiding place, and Jack turned out to be quite experienced with one of those. She tried to stifle her moans as he began to lick and suckle the sensitive nub, occasionally letting his large incisors brush over it but never actually biting down. Combined with the vigorous pace of his humping, she was finding it harder than she'd initially expected to keep her noise down.
Jack seemed to enjoy the sounds she was making, considering he seemed to be doing his best to get her to keep making them. He'd hooked one hand under her knee and pulled her leg open just a little wider, and since she didn't mind holding her, Jane wriggled her rump until her mound was hanging just a little past the edge of the exam table.
It was a small change but it allowed Jack to drive very last bit of his shaft into her, the sounds of his humping now accompanied by wet smacks that rang out in the tiled room. The boy straightened a little and released her nipple from his muzzle. A bit of a disappointment, but the need for oxygen had clearly won out.
And she could hardly fault him for being winded. Her little remark about pleasing grown women had hit home, and Jack was obviously eager to prove that he could get the job done. She had to admit he was quite a sight as the muscles along his young body flexed, his hips a blur as he rutted her with everything he had. 
For her part she was having a harder time keeping quiet than she'd expected. The kid's enthusiasm made up for an obvious lack of experience, his thrusts now so rapid that she could no longer tell whether he was pushing in or pulling out. It was all just blissful, glorious friction, a toe-curling experience made all the more intense by the fact that it was a boy barely into his teens doing it to her.
She was close now, and as his eyes drank in the sight of her she wondered if he'd be able to tell. Her hood was fanned as wide as it would go, little muscles along her trim belly shuddering as her climax approached. But it seemed her lover was to torn between the sight of her bouncing breasts, or the scaly slit splayed around his wet length to notice the subtleties. That brought a smile to the snake's face, since she knew it would only make the surprise more intense for him when she finally did.
And she was achingly close. She knew it wouldn't take much - a tweak of her nipple or a feather-light touch against the reptilian clit now pressed against the length pistoning in and out of her. But she felt that would be cheating, or worse yet that it could make the young rat feel like he wasn't quite enough for her.
It was when the teen railing her changed his stance just a little that it happened. He'd shifted inside her so that the blunt head of his cock was now slamming into a very sensitive spot, the sigh torn from Jane's throat melting into a long, loud hiss as her climax finally hit her. The length pummeling her g-spot paused for a second, the young rat caught off-guard when the snug serpentine sex seemed to come alive, twitching and pulsing around him in a way that had the boy clenching his jaw. To his credit, he picked up the pace, but Jane could tell he was at the end of his rope.
"Nurse Reid... I'm -ngh!- close..." he grunted, showing a little more sense than Jane was by asking whether or not it was safe for him to finish inside her. She knew for a fact that it wasn't, but at this point nothing could have pulled the boy from her, a fact illustrated by the way her tail was coiling around the kid.
"It's okay... come inside me..." she hissed, still savoring the bliss of her own climax as she anticipated Jack's.
The drove himself as deep as he could and almost collapsed on top of her, burying his face in her cleavage as the cock now hilted in her femininity surged to life. She cradled his head against her breasts and kissed the top of his head, the post-coital sensitivity of her velvety tunnel allowing her to feel every twitch of his cock and every gush of cum he sent surging into her. And as his warmth filled her and she felt him huffing into her chest, she found herself hoping those little rodential swimmers would find the egg she knew was growing inside her.
 
*******
"Well, here it is!" said Anita as she opened the door, Jane's hood flaring a little and betraying her surprise.
"Goodness! I was sure they had just re-purposed some old storage closet and were making a big pomp of it..." the snake said as she followed her reptilian friend and colleague into the school's brand-new nursing room.
"I'm sure someone in the administration had just that in mind, but they could hardly get away with it. There's quite a queue for this room already..." she said, nimbly side-stepping the fact that while they weren't the only school to have a rise in pregnancies, they were a curious case since many of the suddenly expecting mothers were faculty rather than careless teen-aged girls.
"And you're quite near the front..." Jane said, gently giving the crocodile's taut tummy an affectionate rub, a small liberty since the two reptiles had become good friends during the cobra's time at the school.
"Get all those belly-pats out of your system while you can! This is my last week before I go on maternity. And when I come back, I'll be the skinny one!" she teased and they both laughed at the image.
Anita Choudhury was anything but overweight, but as a gharial she was decidedly more robust than her slinky friend. She matched Jane in height, which was impressive considering the length of the cobra femme's neck, but her frame had more muscle than the snake's and the parts that were soft and rounded were also more generous. All and all it would have been an attractive but imposing figure, if not for Anita's face.
Despite the impressive array of teeth, Anita was a very warm and kind-hearted person, and combined with the characteristic eye-ridges, up-turned nose and narrow muzzle her species was known for she looked more cute than anyone descended from apex-predators had any right to be. And in Jane's opinion she also carried her egg better. Even though she was almost due to lay it, her belly looked elegantly rounded, the bulge complementing her wide hips and a pair of breasts that had been eye-catching even before pregnancy caused them to swell.
And then there's me... she thought, smiling a little at her self-pity. In truth she was still turning heads despite the fact that she'd been forced forgo her trademark tight-buttoned top for something a bit roomier in the waist. And her own bump looked quite fetching right now, but while someone seeing them together might think they were equally far along, the cobra knew that she still had a month before she laid hers, and would look quite silly by the time she went on leave.
"I have to say, I love the furnishings..." she said as she picked out a particularly inviting bean-bag and almost plopped down into it before remembering the egg she was carrying and settling down gently. There was also a corner sofa and a sturdy looking arm-chair that looked like it was designed to take the weight of bovine or pachyderm mothers.
"I'm glad you do, those were my idea..." the gharial gal beamed, choosing a bag next to Jane's and sighing as she rested for a bit. "I know how hard it can be for women with tails like ours to get really comfy on regular furniture..." she said and Jane just nodded in agreement. Most reptiles had serious tails, and even when you bent them out of the way you usually ended up taking up a lot of space. They both wriggled in contentment against the soft seats, but a slight wince from her friend made Jane's head whip to one side.
"You okay?"
"Yeah, my chest is just a little tender since this morning..." Anita said dismissively, but Jane wasn't quite as ready to let it go.
"All right, get your top of and let me take a look..." the cobra said, quickly rising from her bag and locking the door.
"You should buy a girl dinner before saying something like that. Look, I'm a biology teacher I know enough about my body..."
"And I'm a doctor of medicine slumming it as a school nurse, so I know more." The cobra said, her stance and her face telling the croc femme that she knows a difficult patient when she sees one, and that she knows how to deal with the difficult ones.
Anita rolled her eyes but did as she was told, undoing the buttons of her sweater to reveal a sturdy-looking bra that nevertheless seemed to be struggling to contain the bounty of reptilian flesh. To her credit, Jane's interest remained professional even after her friend unhooked the bra and let her scaly mounds bounce free. She carefully palmed the two crocodilian breasts, keen eyes scanning for any unusual lumps or swelling. As it happened, she made her diagnosis the moment one of the gharial gal's nipples shot a thin stream of pearly-white milk across her muzzle.
"Oh my! I didn't think I'd be producing this soon. With the twins it happened only about a week after I'd laid them..." Anita said, a little embarrassed at having sprayed her friend, but also trying not to laugh at the surprised look on the snake's face. A difficult task since the cobra looked quite silly with both her slitted eyes focused on the offending nipple.
"Well not every pregnancy's the same..." the snake replied, still holding the two hefty reptilian tits. Unbeknownst to her friend, Jane's own milk had also come in, and since it really was a bit early she'd had a look through some material and found out it was a common occurrence for reptiles carrying a mammalian child. She'd made a joke a few weeks ago that Anita had the look of a woman who was 'getting a little something on the side' and with this new bit of information she made a note to try and wheedle a few juicy details from her friend.
"Uhm, you're still -ooh!" Anita gasped. She was about to remind the snake that she was holding on to her bosom even after discovering her little problem, figuring the cobra must be lost in thought. But when Jane gave both her mounds another grope and sent fresh streams of her milk shooting across her head, the cobra's stare no longer looked silly.
Jane's forked tongue flicked out, picking up the white droplets scattered on the scales covering her muzzle. She'd woken up a little frisky that morning but hadn't taken care of her needs in the hopes that a certain black-clad rat might find the time to pop into the nurse's office. And now that she had Anita's luscious mounds in her hands, the taste of her on her tongue and that little gasp still echoing in her ears she was a little hesitant to just let go of her.
She hadn't craved female intimacy in some time, but the snake was certainly no stranger to it. She wasn't sure about Anita's feelings about the whole thing, so she decided to try her luck but take things slow. She brought her muzzle closer to one of the crocodilian femme's breasts, flicking her tongue out over the stiffening nipple, her hood fanning out a little as she got a tiny moan for her efforts.
"D-don't stop!" Anita gasped, giving Jane all the encouragement she needed.
The cobra opened her mouth and pressed her lips to her friend's breast, moaning into the soft feminine flesh as the croc's milk flooded her muzzle. Fingers worked busily across the front of her uniform, and once the last one was undone the cobra shrugged off her top and flung it away, enjoying the sensation of the gharial's scales against her own. She gave her other teat a good squeeze and shuddered as the thin stream of Anita's milk flew over her shoulder, the tiny droplets splattering all over her now bare back.
The croc femme was encouraging her, her low, amorous moans coming in as steady a stream as her milk was. It only made Jane eager for some stimulation of her own, but since her friend her allowed her breasts to swell up to the point that they hurt, she figured she might as well as have some fun and help her out at the same time.
She shifted a little on the large bean-bag chair, careful not to rest her weight on the gravid gharial. And as her own egg-bump rubbed against her friend's, she couldn't help but wonder who the father of her hatchling would turn out to be. Well, the baby certainly wouldn't go hungry she thought as she lovingly nursed from the other female's pillowy breast while her hand groped and squeezed the other milk-laden mound, the opalescent droplets now streaming down her scaled back.
"Mmmh.... If I'd known that you like women, we could have been having this sort of fun a long time ago..." Jane hissed, before bringing her lips back to the panting gharial's breast.
"I -aah!- didn't... that is I've never..."
"But you want to don't you?" she asked, switching between the two hand-filling mounds.
"Mmm-hmm..." Anita whimpered out, obviously closer to her peak than the cobra had guessed.
When the croc femme's streams had died down to a trickle, Jane decided it was time they had some mutual fun. She gave her friend a quick kiss before rising and helping her do the same. Their eyes remained glued to each other as they shed what was left of their clothes, the cobra's mind working frantically to think of a fun way to introduce Anita to the world of feminine intimacy.
"Okay, now lie back down on your side..." she said, motioning to the recently vacated bean-bag.
"Hey, how come you're the one giving orders? I'm bigger than you are..."
"Yes, and I'm the one who knows what she's doing..." the cobra insisted as the gharial rolled her eyes but smiled as she settled down.
She carefully settled down with the other woman's leg resting against her chest, maneuvering her dripping honeypot to the now exposed crocodilian slit. The feeling when her slit touched that of the reclining reptile was heavenly, but Jane knew from experience that the fun would only start when the movement did.
At first she just gently ground her sex against Anita's, savoring the eager noises she was making as they became decidedly impatient. Her friend seemed almost as sensitive down there as she was, which made her confident that she'd be able to get the croc off. After they'd both taken all the teasing they could endure, she began to move her hips, a very subtle back-and-froth motion that nevertheless made a huge difference where it counted.
She smiled at the shuddering moan that escaped Anita's lips before she remembered where they were and how important keeping quiet was. This was her favorite way to fool around with another woman, and something that worked best with a fellow scalie. Soon the gharial femme's hips began to move, thrusting and grinding against her own sex as her friend sought her release.
The sensation of the tender flesh of their exposed inner lips was a subtle delight, but the real toe-curler was when that sensitive flesh wound up being rubbed against the finest, tiniest scales on a reptilian woman's body. To Jane it felt like hundreds, if not thousands of impossibly small fingertips running along both her silken folds and the tiny little nub at the top of her sex.
They had kept at it for... well, too long if she was being honest. Quite frankly they were lucky not to get caught as they ground and rubbed their slits together, both women climaxing several times and stopping only when Jane had finally run out of steam. She'd collapsed next to her lover, the two of them kissing between panting breaths, their legs still entwined and their hands affectionately caressing each other.
When they finally untangled themselves neither of them could help but stare at the mess their efforts had made. Fortunately Jane carried a packet of sanitary wipes in her purse, and the two had gone through the entire pack before they and the bean-bag were clean. They opened all the windows and hoped that the lingering evidence of their encounter would be gone by the time someone walked in, sharing a quick kiss as they promised each other to find time for more of these little encounters, albeit at a more sensible location...
*******
"You know - unf!- I do appreciate you being careful and considerate, but just because I'm carrying an -aah!- egg doesn't mean you have to walk on eggshells, so to speak..." Jane said, lying back and trying to get Jack to show her that youthful vigor that she found so attractive.
Her rounded belly obviously wasn't a turn-off for the boy, as evidenced by the stiff rathood even now slipping in and out of her wet sex, but it had made him a little too timid for her liking. She'd wrapped both her tail and her legs around him in an effort to get him to rut her harder, but whit little success.
"Well I -ngh!- can't help it. Ever since you told me..." he replied, and Jane couldn't help but smile as she remembered the expression on his face. She'd assured him that she was merely telling him because she felt he had the right to know, and that she didn't expect him to be a father at his age. It seemed to come mostly as relief, but some part of him didn't seem to mind the idea of becoming her mate...
"Mhh, I guess I'll have to take charge then..."she said, playfully pushing the boy away and out of her as she sat up, the look on her face as her eyes fell on his slick shaft telling him that their little encounter was definitely not over.
Once Jack was lying flat on the exam table she climbed on to both it and her young lover, her eyes sizing him up as if she were a feral cobra that just caught sight of her prey. She carefully nudged his girthy length until she could feel the tip parting her lips, pushing backwards and downwards without hesitation and easily taking the whole length into her soppy sex.
She hissed in delight as she swiveled a little on top of the groaning rat's crotch, savoring the way his shaft rubbed various spots within her before she decided she needed more than just a bit of rubbing. The weight of her egg-laden belly didn't hinder her graceful movements, her back arching and flexing as she rose and fell on the young male's shaft.
Not quite as good as having the boy pump away between her legs, but more satisfying than letting him tease to madness by what he perceived as necessarily gentle lovemaking. He seemed stunned at first, just lying down and letting the amorous serpent ride him, until Jane grabbed hold of his wrists and pulled his hands up to her chest. That seemed to remind him that there was still plenty of work for him to do, and the cobra hissed as he began to gently kneed her scaled mounds.
Jane had never stopped moving, bringing her hips down sharply on the boy's crotch but lifting them off his shaft slowly enough for her to savor her lips clinging to the smooth, wet length. Jack's by now practiced caresses had coaxed out her nipples, and the next time he gave her scaly mounds a squeeze two streaks of the cobra's milk shot out across his chest and face. A bit of a waste, especially since she knew the young rat enjoyed draining her lush teats during their little sessions, but he seemed to like the sight of thin streams shooting from her nipples and leaving white marks all over his fur. They'd been entirely engrossed in the shared sensations of their lovemaking, until the sharp clatter of a metal tray hitting the tiled floor made them both freeze and turn towards the sound.
"What the... Aaron? What the fuck are you doing here?" Jack asked, getting up on his elbows and hissing at the still wide-eyed oryx standing with his back against the door.
"What am I... what are y- that is to say..." the stunned teen stammered while Jane's thoughts raced.
Getting caught like this had been the worst case scenario of her little get-togethers with Jack, but considering who caught them she suspected there was still hope. She knew that Aaron was Jack's friend, making them unlikely couple since the oryx was a jock. Forgetting to lock the door had been her blunder, but she dismissed the idea that the young bovine had just walked in on them at that moment once her slitted eyes caught sight of his crotch, and the outline of an impressive shaft that had been stiff for a while. This also presented her with an opportunity to get out of trouble, one that she intended to seize.
"So, Aron is it? And how long have you been watching?" she asked, her tone casually curious and obviously a welcome change for the oryx compared to the glare Jack had been giving him.
"N-not long! I mean... I didn't even mean to look. Jack, you've been going to the nurse's office several times a week for a month now, I was worried something was seriously wrong with you!" he protested, still unaware of the bulge betraying him.
"Well, I'm sure you're relieved to see there's nothing wrong with his health. But you did catch us in the act so tell you what - if you'd be willing to be a good friend to Jack and keep our secret, we could make it... our secret." She said, tossing the bull a wink and swishing her tail in a way that would draw his eyes where she wanted them to go. 
Jack was about to say something, but stopped when she pressed a finger to his lips. While he might not be thrilled at the idea of sharing her with a friend, he was smart enough to realize that this was the only way they had of avoiding serious trouble. As far as she was concerned, it wasn't much of a hardship. She'd been curious about threesomes, but had never actually been in one. And while this wasn't an ideal situation, the boy behind her looked well-built and as the meaning of her offer dawned on him quite eager.
"Y-you mean..."
"Mm-hmm. But I'm sure you wouldn't want to spoil your friend's fun, so..." she trailed off, and when she raised her tail a second later, the light suddenly went on in the oryx's blood-starved brain.
The exam table creaked when the young bull climbed on, but they were made with all species in mind, so if it could bear the weight of an adult elephant she was reasonably confident that the three of them wouldn't wreck it. And when she caught sight of what the bull had been hiding in his pants, she hoped she would fare as well.
The oryx was gentler than he looked, hooking a thumb into the crack of her ass and gently pulling one firm cheek to the side, pausing to admire the sight of a winking pucker nestled between them. As the spurting tip of his cock was pushed against her ring Jane made sure to relax. She'd taken males under her tail before and was fortunate that the long, gently tapered length the bull was packing was ideal for a gentle insertion.
Once she'd relaxed for him it took very little pressure for the boy to sink his tip into her, the bovine rod squirting inside her snug ass her and making the rest of him easier to take. He stopped when he heard her hiss, and she couldn't help but smile as he misinterpreted the sound for pain. In order to reassure him and feel more of him inside her she gently wound her tail around his back and pulled him a little towards her.
She bent over to give the young man better access, carefully laying her bulging bely against Jack as she brought her chest within reach of his muzzle. He didn't need more encouragement than that to latch on, and soon the milk that hadn't squirted out while he was playing with her breasts was streaming down the eager rodent's throat.
Having two boys inside her and one skillfully nursing from her did wonders to melt the tension she'd felt when they'd been caught, and the sensation of Aaron's long cock pushing further into her only served to make her sex tighten around Jack's rod. Jane had taken some very large males in her life, but she'd never felt so deliciously full as she did then, her tail-hole pulsing gently around the oryx's length as it got thicker the closer she got to the base.
Her pleasure mounted with every inch that sank in and when she finally felt the fur of his sheath tickle her pucker her body tensed as her orgasm hit her. It was a quick one, enough to make both her slit and her rump pulse around the boys buried inside her and make her eager for the real thing. Once her body had calmed down a little she began to slide forwards, letting out a long, low hiss as she felt herself slide off the twitching members and moaning louder than she should have when she pushed herself back onto them.
The teens' voices soon joined her own, the shafts impaling her drooling both in her cunny and her ass, making her wonder what it will feel like to have both of them fill her up. She knew for a fact that Jack was quite productive, so to speak, and she had the egg to prove it. And remembering the sight of the heavy pouch dangling between Aaron's legs, she was sure her ass would be just as messy by the time the boys were spent inside her.
For all her earlier bravado, Jane found herself running out of energy sooner than expected. She wasn't sure if it was the pregnancy slowing her down, or if her climax was responsible for the trembling in her limbs. Fortunately Aaron picked up where she left off, either consciously or possibly acting on a mating instinct.
The room was soon filled with the muffled slaps of his furred body hitting her scaly ass, his thrusts vigorous enough to bounce her up and down a little on Jack's length. The cobra honestly had no idea how long it had lasted, having lost herself in the blissful sensation of two throbbing cocks rubbing her in all the right places.
Aaron turned out to be the first of the two to reach his peak, his impending orgasm announced when his strokes became quick, urgent jabs against Jane's scaled behind. Either the snake hadn't realized how close she was to her own climax, or the excitement of having the young bull fill her behind pushed her towards it. She urged him on with what little breath she had, tightening and relaxing her pucker around the invading length and feeling it twitch and throb in response.
The sensation of heat blossoming deep inside her was more than she could stand, her second climax hitting her with such force that she felt close to passing out. She did manage to cling to consciousness and was glad she did, since Jack's orgasm had followed closely on the heels of her own. No doubt the feeling of her already snug sex milking him in a frenzy was too much for him to bear. Aaron was still spurting his load under her tail when she felt Jack begin filling her. The warmth that she'd felt was now a heat and she found herself basking in it as surely as a feral snake did in sunlight.
Jack had released her breast in order to breathe, and once she was sure he'd gotten some air she bent her neck and kissed him, tasting a bit of her milk on his tongue as it wrested briefly with hers. After letting the young rat breathe, she craned her long neck and brought her lips to the somewhat surprised oryx's muzzle. To be honest, he was a bit of an uninvited guest, but as his shaft slowly softened inside her well-bred rump Jane had to admit he was nevertheless a very welcome one.
 
*******
"Unf! You're bigger than I thought!" Jane grunted, fists clenching her sheets as her abdominal muscles tensed, trying to push out the egg past her straining lips. Laying an egg had never been a problem for her, but she knew that a fertilized one was almost always bigger. She reached down between her legs and felt some relief when the tips of her fingers found the smooth surface of the shell between her splayed folds. The baby was coming along, and now she just had to push through the hardest part.
She paused a little, laying on her back and gathering her strength before pushing again. She used her fingers to try and pry herself as open as wide as she could while using the other hand to very gently press on the part of the bulge closest to her chest. But despite the strain and the little aches she could feel that special sensation that laying an egg always brought on. Something not exactly sexual, but not far off.
As she gave another push, Jane knew her efforts were paying off. She could feel a bit more of the wet surface of the shell as her slit expanded around it, albeit slowly. This she knew was the hardest bit, as her body stretched around the widest part of the egg. She gave another hard push, straining as she felt her lips being pried wider and wider until the stretching stopped and she allowed herself a sigh of relief.
She smiled as she gave the push that, as she suspected, would be the last. She hissed in relief as the effort pushed the egg past her lips, her belly once again flat as her chest rose and fell. It was tempting to just lay there and catch her breath, but she was too eager to see her soon-to-be hatchling. A quick roll and a crawl got her face-to-shell with the egg, and while it had been bigger than any of the unfertilized ones she'd laid, it still didn't look as big as it had felt passing through her.
But her grin still reached the little holes that were her ears as she regarded her future child. After some quick work with wet-wipes and paper towels she had the egg clean and snug in the little 'nest' she'd prepared. She'd considered getting a hatching crib, but since she didn't have anyone sharing her bed, she figured she might as well get a little broody and spend her nights snuggled up with her little bundle of joy. She carefully placed the egg on a heating pad before wrapping a blanket around it, leaving about a quarter of it uncovered but making sure it was secure.
"Now let mommy get a good look at you..." she said, taking a flashlight and pressing it to the exposed surface of the shell. Mammals had been forced to wait for the invention of the ultrasound device to see what she was seeing now, but for egg-layers like her a light source had always been enough to give a mother a glimpse of her developing child. She smiled warmly at the sight of the little embryo and grinned wider when it moved, responding more to the warmth of the torch rather than the actual light.
"All right, I won't peep on you too often! Just making sure you're okay in there..." she said, switching off the light and lovingly petting the surface of the shell, feeling a strange maternal thrill at the knowledge that her baby was just under it. "Now let's turn on your heating before getting an ice-pack for mommy..." she cooed, turning the little dial to a nice incubating temperature. 
"Then I suppose I should start thinking up some names for you..." she thought as she came back from the kitchen, laying down next to her egg and wincing a little as she pressed the cold pack to her crotch. "Mmmh, maybe not tonight. Tell you what, we'll see if we can get your daddy to drop by tomorrow and ask him if he has any ideas..." she cooed, snuggling up to her little bundle of joy. She had just enough sense to pull a blanket over her own naked body before she drifted off, the only sound in the room being her soft, hissing snores.
