Two months ago...
"I think we should have foals."
You almost fall out of the air. "What?!" you ask, rapidly flapping your wings to reach her altitude again.
"We should have children," repeats Nightshade, turning towards you. "I hope you know what that entails," she adds with a sly grin, exposing her distinctive batpony fangs.
You roll your eyes. "Yes, yes, I am entirely aware of the process for creating small little clones of myself. What concerns me is what happens after we initiate that process."
Giggling, she swishes her tail. "Oh, afraid of the little ones, are we?"
"In a manner of speaking." You dive down, waiting until your leathery wings catch an updraft before soaring into the sky, zipping past your wife.
"So?" she calls up, not in the least bit perturbed by your sudden change in altitude. "Do you want foals or not?"
Her words carry easily through the calm, evening air. You hesitate. Deciding to have kids was a big decision.
It's quiet, and the only sounds are the wind whipping past your curved ears, and the soft beating of leather wings. Warm air rushes around you, tickling your fur, and sunlight glints off a distant lake as you fly across the eastern coast of Equestria. Rivers snake through green hills, and forests dot the landscape. The sky is clear, with nary a cloud to be seen. The calm serenity of flight is a joy known only to those with wings, giving the sky a voice to speak with, calling every being born with wings to the place above the clouds, where dreams take flight.
This evening, however, it seems that something else entirely would be taking flight.
"How many months is it until you go into heat?" The question is simple, but it's implications are many.
"Two," replies Nightshade, barely able to restrain the growing excitement in her voice.
"I'll have foals with you—" You are momentarily cut off by a joyful squee~ emanating from your wife's direction, but you continue on. "On the condition that we travel the world and see all the things we haven't seen yet. We won't have the chance after you have foals."
Nightshade doesn't reply. Instead, the wind is knocked out of you as a dark grey cannonball slams into you, gripping you in a bear hug and smothering you with kisses.
You love this mare.
Two days ago...
The Neighagra Falls were truly a sight to behold. Towering columns of water cascaded over a massive ridge and crashed into a basin nearly half a mile down. Huge clouds of mist slowly rose towards the heavens, minting a thousand tiny rainbows in the afternoon sun. Near the edge of the falls, trees hung over the precipice, defying gravity with their strong roots that dug into the hillside. It was here that a large building was nestled in the bosom of nature itself, hidden away from civilization.
In short, it was the perfect place to fuck.
In fact, the only thing you two did after dinner yesterday was fuck each other senseless, over and over and over, until you collapsed from exhaustion. The original plan had been to do the same thing tonight, but it seems that there have been some... complications.
"You're in heat already?!"
To be perfectly honest, you had considered this a distinct possibility. Going into heat is not an exact science, and any mare's estimation of when they go into heat comes with unspoken fine print: give or take 3 days. You had been hoping, however, that it would have been in the other direction.
"Yes, honey," Nightshade sighs. "I'm sorry, I know you were looking forward to this, and I really wanted to make tonight special, but..."
"No no no, Nightie, it's fine." You pull her into a tight hug, nuzzling her cheek. "You aren't in control of your body, there's nopony to blame but Mother Nature."
She snuggles her head against your neck, returning the embrace. "I'm just frustrated. I wanted everything to be perfect, but now..."
You look out the wall-sized window as the afternoon sun illuminates a breathtaking view of the valley below the falls. "As far as I'm concerned, this is perfect."
Suddenly, you feel Nightshade's lips press against yours, and you reflexively open your mouth to let in her tongue as your heads tilt in opposite directions. Her tongue slides over yours, and the taste of her saliva fills your mouth. The world washes away, until it's only you and her, wrapped in a timeless embrace against the onslaught of reality.
Finally, the two of you separate, and your wife's half-lidded reptilian eyes gaze into yours. "I love you so damn much."
A small, bashful grin finds its way on to your face, and you bat a hoof at her. "Aww, it's nothing, really."
Her gaze travels down your front, and stops on your sheath, still hiding your stallionhood from view. "I have... other orifices, you know."
You blink. "You mean like... anal? You've never wanted to do anal before."
Her eyes snap back up to yours, and she shrugs. "First time for everything, right? Besides, we're not going to get a chance to experiment like this after we have kids."
It was a good point, but you didn't really want to do anything she didn't want to do. Your dick, of course, had no such worries, and was rapidly sliding into view. "A-are you sure? I mean, we don't have t—" You don't get a chance to finish before her lips lock with yours again, and she hungrily starts rubbing her body against yours.
"Mmmmm," she moans into the kiss, before your lips separate, and a tiny thread of drool spans the distance between them. Her eyes are full of desire, and your dick is rapidly reaching full mast. She leans down and gives it a nice, long lick, her tongue stroking it from the base to the tip. Her mouth slides over the top, enveloping it, and you moan in response. She sucks at it lovingly, before lapping at it over and over, slathering it in her saliva.
Before long, she turns around and starts wiggling her sexy flank at you, lifting her tail. "Come and get it, big boy!"
You need no encouragement. In a flash, you're upright and mounting her, carefully navigating your cock towards her tight asshole. As the tip pushes up against it, you reflect that it's a bit of a weird feeling, deliberately trying to fuck her in the wrong hole. She slumps slightly beneath you, relaxing, and your shaft starts to slide into her, inch after inch—
"Ow!"
You immediately back off. "Are you ok?!" Your hoof immediately begins to stroke her side, and you can feel your penis begin to lose its hold on her anus as your arousal is rapidly replaced with concern for your wife's well-being.
Nightshade grunts. "I'll be fine," she says. It's a lame excuse, and you both know it.
"Nightie, I don't want to hurt you, it isn't sexy if you're getting hurt..."
"Oh come on, stop treating me like a baby. I can take a bit of pain—I'm kinky like that." She matter-of-factly pushes back and forces more of your dick inside of her, and you moan in response.
"Unf, okay, fine, but if I'm hurting you, say stop and I'll stop." Your member rapidly makes up for lost ground, and soon you can feel her tight ass clenching around your rock hard erection as you pump in and out.
"Come on, fuck me harder!" she calls out, "Harder!"
You oblige her, pulling almost all the way out, and then thrusting all the way in until you've hilted, your entire throbbing shaft embedded inside her.
She let's out a cry that's an odd mixture of pain and ecstasy. "Guh! Yes! Make me your bitch! Make me your little slutty bitch!"
You get down to properly rutting her, smacking your balls against her vagina as you pump in and out of her tight ass. Your cock savagely fills her all the way to the brim and then pulls back, over and over and over, and she seems to be greatly enjoying the sensation of being ravaged by your cock, even if it's in the wrong hole. "Oh yeah, oh yeah! I'm, unf, your little, unf, sex toy, unf, oh Celestia yes!
It doesn't take long before you feel a pressure building up in your testes. "I, unf, I think I'm gonna, unf cum!"
"Yes!" she cries out, "Cum in me! Make me your little slut!"
You waste no time in obeying her as you grip her sides and slam her down onto the base of your cock. She lets out a cry as the tip of your penis erupts with fluid, slathering her insides with horse semen.
"Oh Celestia, it hurts," she moans as you unload yourself into her, "it hurts so good."
As your cock finishes pumping its load into your wife, you both sink into the bed, basking in both the sun's rays and the afterglow of sex. Eventually, you slowly pull out of her, and you're alarmed to see a few flecks of blood mixed in with the semen. "Are... you going to be okay?" you ask, still a bit winded.
She has a blissful smile on her face as she stares into the setting sun. "I feel... used," she ponders. "I like it. I like being your little fucktoy, you sexy, handsome stallion."
You can't help but blush. "I, well, that's good, but are you going to be able to, y'know, walk?"
She bats a hoof in the air. "Doesn't matter, had sex."
Sighing in defeat, you lay your head across her stomach, and enjoy the view of the waterfalls in front of you against the warmth of your wife's fur. It was a shame you'd never get another chance to see it, after your wife had foals.
Foals are a big responsibility, after all.
Two hours ago...
"Your suite is on the third floor. Have you already filled out the paperwork?" A neatly trimmed stallion stands behind a gold-plated desk in the reception area. The hotel looked like a palace from ancient times, with pearls and diamonds on chandeliers hanging from an enormous curved ceiling, to gold trim covering every inch of the walls. It was a very special hotel, one where you could only stay a single night. There was a bit of paperwork to fill out, too, but your wife had already taken care of all that. It wasn't cheap to stay at a hotel like this, even just for a single night, but like most batponies that were about to conceive foals, you would settle for nothing less.
"Yes," your wife confirms, pushing a manilla folder on to the desk.
Picking up the folder, the secretary skims through its pages, peering at them through his monocle. "Well then, everything seems to be in order. May Celestia bless you and your foals." He nods to my wife. "Ma'am, ring the bell when you need service."
You both nod, and nervous energy sends tingles through your spine. You're really here. You're really doing it. You're gonna have foals. You both trot up the stairs in silence as you nervously ruffle your leathery wings.
"What is it?" asks your wife in a gentle voice, knowing full well that you have every right to be nervous on an evening like this.
"I'm just... worried about the foals," you mumble, not looking at her as you both continue to plod up the stairs. "You know I can’t be around for them."
"Well, you did marry me," she says with a small smile, "I hope you think I can handle a few fillies and colts running around the house."
You reach the third floor and begin walking across a dazzling bridge adored with gems and gold and silver, all shimmering in the evening light. You make it to the center before your wife puts a hoof on your withers, and you pause, looking over at her.
"Listen, are you sure you want to go through with this?" Her ears pine back in concern. "We can still do it next year."
You don't answer immediately. You trot over to the balcony and dangle your forelegs over it. The sunset is gorgeous, illuminating a beautiful forest in front of you, with the tip of the ocean just visible in the distance. Clouds ripple through the sky, reflecting the sun's dying light in yellows and reds. The view is breathtaking.
"Yes," you finally reply, "I'm sure. I've seen enough now, I think. Besides, I'm almost 30, I'm getting awfully old for a stallion. Soon all the young colts will be giving me strange looks." A small chuckle escapes your lips. "It's a pity I won't get to see anything like this after we have foals, but that's life, I guess." You turn around and give your wife an affectionate nuzzle. "I'm just glad I got to see it with you."
She returns your nuzzle with a passionate kiss, and you notice that her eyes are all teary. "I love you so much," she breathes, "and I swear I won't let you down. Not even for a day."
You wrap her up in a tight hug, and enjoy the sensation of the evening breeze across your fur. "You could never let me down, Nightie."
After a long embrace, the two of you separate and make your way to your suite. After unlocking the door, you are greeted with an incredible sight. The entire room is made of gold, and a huge, steaming banquet is laid out in front of you along a counter. In the middle of the floor is a circular depression, like one would find in the shower. To the left is a bathroom fit for a king, and to the right is a majestic bedroom with an enchanted cloud bed.
"Wow..." you whisper, subconsciously wrapping a wing around your wife.
"No kidding," she says, and gives you another peck on the cheek. "Come on, I'm starving!"
After letting the night’s dinner settle, you both trot over to the depression in the floor, horny and eager to begin. Your wife flops onto the floor, with her hind legs raised and spread, with her marehood positively dripping with arousal.
"Sweetie, I'm going to try to say this nicely, but I'll only do it once," she coos. "FUCK ME!"
Knowing better than to tease a mare in heat, you immediately dive in, stuffing almost half your muzzle up her marehood. This has the side effect of making it impossible to breath, but thankfully, you're pretty good at holding your breath. You eat her out relentlessly as the smell of her arousal almost suffocates you. Pulling out to take a breath, you dive back in, your tongue traveling along the slick sides of her vagina, sliding up and down and eliciting screams of pleasure from your wife.
It is not to last, however, as the ever increasing scent of her arousal makes your hornier and hornier, until your penis is rock hard and practically dripping with precum. Finally, you can't take it anymore. Separating your muzzle from her cunt, you matter-of-factly ram the entire length of your penis inside of her.
It slides in easily, accompanied by moans of delight from your wife. You push in as far as you can go, burying your cock inside of her as your chest fur brushes up against hers. You lock lips with your love, holding her in a tight embrace, with your throbbing shaft buried inside of her warm, inviting pussy. You break away from the kiss and rise up, before slamming your cock back inside of her. The sides of your penis are slathered in vaginal fluid, and your shaft slides past the lips of her marehood with barely any friction at all. You mercilessly pump your stallionhood in and out of her, and your balls slap against her tight ass.
She shrieks in ecstasy as you ravage her, thrusting your thick cock in and out of her like a piston. You lean over her and give her ear a nibble, and she kisses the side of your cheek in response, even as your continue to thrust inside of her. Holding yourself up with one hoof, you use the other to lightly caress the leathery edges of her wing, sending shivers of delight through her.
She grabs you with her hind legs and pulls you inside of her, hilting your cock as she smothers you with a kiss. At first, you aren't sure what she's planning, but then you feel her forehooves brush the edges of your wings, and you almost lose it. Mind-numbing pleasure shoots through your wings and into your back as she gently massages your leathery appendages, and her cunt pulses and squeezes around your member as though trying to milk the cum right out of it.
It quickly becomes too much to bear. "Ohhhh, I'm gonna cum!" you say, and your wife releases your wings. You rear back before thrusting into her again, pumping your penis inside of her a few more times before bucking your hips one final time. Your forehooves drag your wife down on to your penis as you push into her with all of your might, and cum erupts out of the flared tip of your horse cock, coating her insides with sticky ropes of white semen. Both of you scream in unison as an orgasm like you've never felt before violently tears away your senses, leaving you momentarily floating on an island of pure pleasure.
Triggered by the hormones emanating from Nightshade's marehood, your brain begins a complex hormonal transformation. As you come down from your high, your blood stream is flooded with beta and gamma endorphins, numbing your pain receptors and preparing your blood vessels for an impending massive drop in blood pressure. A special hormone is secreted by your pituitary gland that suppresses your survival instinct, preventing you from feeling anything other than blissful content.
Meanwhile, your wife's experience is vastly different. As she comes down from a particularly amazing orgasm, her body is flooded with steroids and a brief spike of testosterone. Batpony mares don't just have one child, they have several at the same time, using a bifurcated uterus to stagger the development of each embryo over several months. This requires an enormous amount of nutrients. Moaning in bliss, she looks back up at you with eyes full of hunger.
Her babies need food, and you're the closest meal. Actually, the half finished roast turkey a few feet from your intertwined bodies probably would have worked too, but social norms are persistent, and evolution isn't very smart. Even as you draw out your semen-coated dick from her, your body is running in overdrive, pumping your bloodstream full of nutrients for the foals that were just conceived. Any hope of thinking properly is banished by the cocktail of potent nuerochemicals flowing through your veins.
You stand above her, panting, a partially erect penis hanging beneath you, dripping with various sexual fluids. You're ready for this. You've never been more ready for this your entire life. You want to throw yourself on her, and beg her for what you know comes next. A very small part of you points out how completely insane this behavior is, but it is quickly silenced by another wave of hormones pumping through your veins. Still catching your breath, you lay down on top of her, and she embraces you, snuggling against your fur. Another kiss passes between the two of you, and she opens her mouth expectantly. There is a split-second hesitation, a moment of admiring the point of no return, before you push your tongue into her mouth and underneath one of her fangs, the universal sign for "take me, my love".
She bites down, hard, and blood erupts from the punctured muscle. Your wife greedily drinks down your vitality, still kissing you. You moan as the first wave of pleasure washes over you, your sensation of pain completely inverted.
Suddenly, she breaks the kiss, and aggressively sinks her teeth straight into the nape of your neck, punching through a large vein and almost making you cum a second time. You moan in pleasure as she violently sucks your blood, and your body struggles to maintain enough blood pressure to sustain your rock-hard boner. After a time, she pulls out, and hot blood begins pouring down your neck from the wound.
You find it incredibly sexy. Half delirious, you can feel the nutrients being pumped into your bloodstream, and your mind is taken over by desire, a singular urge. You flop over onto your back, with your erect cock pointing upwards, panting in anticipation. Nightshade quickly straddles you, then smiles, and leans down to give you a kiss. Her lips part, and you push your still-bleeding tongue into her mouth, which she eagerly sucks on. Eventually, your lips part. "I love you," you whisper.
"I love you too," she says, before using her fangs to viciously bite into your penis. You can see her fangs going straight through your erect shaft, and blood spurts everywhere. A thousand nerve endings scream out in agony, but their cries never reach the part of your brain that processes pain. Instead, you almost immediately ejaculate, and your lover patiently waits until the last rope of semen has coated your chest before violently ripping the top of your penis off. Her marehood is leaking vaginal fluid and semen as she sinks her teeth into your cock once again and rips off another bloody chunk.
At this point, you would have fainted from blood loss had your body not been closing off ruptured blood vessels in an attempt to save as much blood as possible for your wife to consume. It also had the side effect of keeping you alive as she slowly devoured your sex organs, which was an intensely satisfying experience.
Eventually, she moves on to your testes, and sinks her teeth deep into your sack. You moan in pleasure, and your battered balls manage to ejaculate one last stream of semen and blood through the stump that was once your member, before she rips off your entire scrotum in a shower of blood. Her chest is coated in your internal fluids now, and you can feel a pool of warm liquid begin to collect under your crotch. It's all very romantic, and you would have had a rock hard boner if she hadn't eaten it already. She straddles you again, and you open your mouth wide as she squeezes one of your tattered testicles between her teeth. Blood drips onto your already bleeding tongue, followed by her leaning in for a kiss with half your testicle still in her mouth. You use your tongue to push it back into her mouth as you kiss, and then slide your tongue along the edges of her razor sharp teeth.
She bites down, and viciously rips off the rest of your tongue. You would have giggled in delight, but there's too much blood in your mouth and it's getting hard to breath properly. She swallows, and then moves on to one of your legs, tearing off bloody chunks of meat, each one sending a shiver of pleasure up your spine as you relish the feeling of being slowly devoured. Your blood collects in the large circular depression you two had sex in, specifically designed to capture all of your fluids so your wife wouldn't miss a drop. As you watch her bloody muzzle work through the rest of your left leg, you can't help but feel proud of Nightshade. She's doing such a good job eating you. You clearly decided to marry the right mare.
Unfortunately, things are getting fuzzy around the edges. Your body is frantically trying to keep as much of itself alive as possible, and shots of adrenaline work their way through your system, but you've lost a ton of blood. Your mouth hangs slightly open, and your eyes are half-lidded, and you think she's starting to devour your internal organs when a blob blocks part of your vision. You realize it's your wife, and you wish you still had the strength to reach up and embrace her with your one remaining arm. She understands, though, and leans down on you, giving you one last kiss. You can't really move much anymore, and it's getting hard to think, but that's okay. She lifts your head for you, leaning into the kiss.
The last thing that passes through your mind is how much you love Nightshade, before darkness takes you, and your heart finally gives up.
Twilight stared at Fluttershy with an expression of abject horror.
"Isn't nature fascinating?" she asks, having finished her erotic story about batpony mating habits.
Twilight would have answered, but she was too busy puking into a nearby waste bin. Eventually, after parting ways with the contents of her stomach, Twilight leaned up and looked over at Fluttershy. "Fuck you."
Fluttershy blushed, raising a hoof to hide two small fangs she had never managed to get rid of. "Oh, I would, but then I'd have to eat you."
