The Naugthy Daughter(-In-Law)
It was father's day. A day to celebrate for all the stallions out there who have sired and raised, or were still raising foals. While some couples hold the celebrations more...chaste, keeping the celebrations simply with going out, and spending time with the family the tradition itself was a far less innocent once.
You have to know this tradition started at a time far less happy and a bit more distraught. A time shortly after the windigos were beaten. The tribes got closer together but were still weak and the winter and starvation had reduced their numbers. In order to change that the newly reunited leaders decided to make some new laws and with that new holidays. One was mother’s and the other one father’s day.
Planned was that these would bring everypony closer together and start an appreciation of maternal and paternal figures. Giving them respect and an image that would encourage stallions and mares alike to gain that title. They simply wanted to give them an incentive to breed, so not only did parents get an advantage in taxes but also their own holiday.
In this holiday, depending if it was father’s or mother’s day one of the figures were freed from their bonds and encouraged to breed with other partners. They should spread their joys and influence around. Show off their sexual skills and bring offspring to the once so foal-starved land.
Considering the suffering the populace had endured by this point it came to no surprise how quickly such an enjoyable tradition took hold as on father’s and mother’s day you could see fornication going on in the middle of the street as mare after mare got impregnated on father’s day, while mothers enjoyed the healthy virile stallions, back then often more than one at a time on mother’s day. Partner swapping was quite often seen during that day. It gave the ponies something to look forward to in these old and cold times.
Of course the tradition of actually breeding around was a less and less used practice over the centuries, turning more to a simple day to enjoy it with the family. Not that the tradition died out though as some ponies still felt themselves bound by these traditions, wanting to enjoy these days to celebrate parents and encourage breeding in the way it was meant to be by the three rulers, who by the way it is said that they have gotten the idea after some rather...heated negotiations.
Anyway, as today was the father’s day there were two specific couples who wanted to celebrate with an old fashioned partner swap. These two couples were Night Light and his wife Twilight Velvet, and their son Shining Armor and his wife the Princess of Love herself, Princess Cadance.
It didn’t really come as a surprise that the idea for this partner swap came from Cadance, the perverted alicorn by title being the most knowledgeable about sexual arts and their traditions. Not that Night Light and his wife were all that innocent either though. Both had a long history of sexual escapades even going so far as screwing with their daughter’s friends, literally. One could say they didn’t hesitate a second to agree and take the next train to be in the Crystal Empire for father’s day.
They soon enough got to the Crystal Empire where a guard led them to some private quarters to meet their son and daughter-in-law. Velvet hugged her impressive bust in her excitement and arousal while Night Light simply grinned in anticipation as they opened the door to a guest room the guard had led them too, before leaving them to their privacy.
As soon as the heavy crystal door was opened they could see Shining Armor. His muscular build he had gained as a Guard Captain made many mares swoon for the stallion.
“It’s great to see you dad, mom,” Shining greeted, giving both of them a hug respectively. Albeit the hug with Velvet was longer as he took both of her taut asscheeks in his hands giving them a squeeze, making his mother gasp out slightly.
“Ooh~ It’s good to see you as well Shining,” she said hotly before both separated, Velvet only lingering for a moment longer, “Happy father’s day.”
Shining smirked as he couldn’t help but to ogle his prize for the day. And Night Light was inclined to do so as well, but alas a certain pink alicorn wasn’t in the room at the moment.
“Excuse me for being late!” a new fourth voice suddenly cut in as Cadance quickly followed into the room.
Night Light couldn’t help but lick his lips as the sight. Cadance was wearing a teasingly short blue skirt. In fact so short that it barely covered her asscheeks completely letting them peek out teasingly, and in return also gave him a glance at her playfully looking striped panties. She also wore a white tight shirt which was too short and only covered her D-cup melons, letting the underside of them also hang out. These melons were also not adorned by a bra, as the outline of her erect nipples could be clearly seen through the shirt. Her hair was done in a youthful looking ponytail. A pair of net stockings were topping it off, together with some applied makeup and a luscious blue lipstick. Her whole picture just outright screamed slutty schoolgirl sex goddess.
Night Light grunted as he felt a tent straining hard against his pants, making Cadance giggle.
“Ooh, seems like someone is really happy to see me~” Cadance teased, while Velvet couldn’t help but snicker along as well.
“You probably will have quite a lot of fun sweetheart,” Velvet teased before eying her son once more, “As will I~” she said with a sultry purr.
“So, we are going straight for the main event?” Shining asked with a grin of his own, “Not that I’m going to complain,” he added before he reached for his mother, lifting her up and throwing her over his shoulder, carrying her like a prize out of the room.
“Heh, have fun you two!” Cadance merrily called after them.
Night Light however simply looked after his son giving him an encouraging grin as he took his wife in such a manner. He certainly taught him well.
Shining might have only gained recently the title of father, but that doesn’t mean he shouldn’t have some fun of his own. And by Celestia he knew Velvet would give his son a great ride, just like he was about to give a ride to Shining’s wife.
His time certainly wouldn’t be any less enjoyable, as he heard Cadance purr from the side. As he turned his head he already saw this pink beauty laid out on the bed before him. Her delicious curves drew his eyes along the soft fur of her body. From her beautiful tri-colored mane to her bouncy looking D-cup breasts and her wide foal-bearing hips, just begging to have another foal planted in them.
“So, what do you want to do with me? It is father’s day, so I’m completely yours for whatever you have in mind~”
Night Light chuckled at his daughter-in-law. She was quite eager and he honestly found it quite a nice touch to this beautiful, as well as youthful looking mare.
His mind was racing with the possibilities of what exactly he should do on his day with his daughter-in-law, and how to discipline such an incredibly naughty filly.
A second later Night Light had an epiphany, his pants tightening under his stiffening rod ever more as he looked at this misbehaving and mischievous little filly.
“I honestly think that you are a very bad filly, if you really want to know. And such bad fillies have to be disciplined!”
Cadance shuddered on the bed she was currently occupying, “Oh? That certainly sounds promising.”
“It does. Especially since I can’t let my daughter walk around like this. Walk around like a common whore!”
A sparkle shined in Cadance’s eyes as she caught on and slowly all too sensually leaned up before standing up from the bed. She then continued to sway her luscious hips towards Night Light who couldn’t help but grin.
“So, ‘daddy’, do you really think you can tell me what to wear?” she teased as she stood before him in a playful defiant pose.
Night Light crossed his arms, “You better believe it! Or do you really think I will accept how you are teasing the guards? You are bringing shame to our family just by strutting around in this whorish get up!”
Cadance stuck out her bottom lip, “Oh puh-lease! I’m a grown up mare! I can make my own decisions!”
“So, like the decision to bring stallions in your room?” Night Light responded with a disapproving stare.
“Y-You k-k-know?” Cadance asked stuttering, while shifting on her hooves.
“Do you really think I would be blind towards a colt sneaking into your room almost every night? Or the noises you make as you fornicated with him? I am old but not dumb little lady!”
Cadance squirmed in place for a while, before she sighed, “Well, to be fair, you never forbade me from fucking around with some stallion.”
“I also never allowed it either,” Night Light said with a sigh, “The way you behave is something I cannot allow, so you are grounded.”
“G-Grounded?!” Cadance exclaimed in shock, “But daddy!” she playfully whined, making Night Light raise his hand.
“No. I’m staying hard on this until you have learned your lesson.”
“I’m sure there is another way to...learn. A way in which I can show you my...goodwill in...another way.”
“Another way?” Night Light asked with a raised brow, causing Cadance to grin as she rounded Night Light like a predator stalking its prey.
She started to push Night Light backwards and towards the bed.
“And what are you planning?” he asked in a stern tone of voice.
“Making up for the stress I caused and showing my goodwill to not get grounded!” she chipperly explained, before her voice turned sultry, “You can simply discipline me in every way you see fit, making sure the lesson sticks. I mean, I am a hard learner so you will probably have to pound it into my naughty frame repeatedly,” she whispered hotly in his ear, before giving it a sensual lick.
“You really are completely depraved. I can’t remember raising you like that,” Night Light commented as Cadance pushed him so that he was sitting on her bed, while she couldn’t help but to giggle.
“Well...there were enough other ponies involved~” she teased, making Night Light arc an eyebrow, but Cadance didn’t elaborate further. She simply turned around and presented her rear to him, before bending over, raising her tail and giving him a rather naughty look. “In any case, I am yours to do as you please. So you can discipline me like that. Just show me what a naughty mare I truly am. I think that would be much more mhmmm, effective~”
“Would it now?” Night Light asked as he put his hand on her asscheeks, kneading the still panty-clad mare.
He then decided to not wait for too long to unwrap this gift as he pulled her stripped panties down her legs until they hit the ground, revealing the treasure that was hidden beneath.
Her tight pucker as well as her dripping sex were on full display, making Night Light hum as he started to unzip his pants and let his meaty shaft plop free, already rock-hard from the sight.
“Oh? Somepony is happy to see me~” Cadance teased, but that only earned a smack to her rump that made her squeak.
“Behave,” Night Light ordered as he took her ass in his hands before pulling it to his cock. Soon enough the both connected and Night Light decided to bury his shaft in the crevice of her plump asscheeks, before using his hands to thrust his naughty daughter’s ass along to please him.
“Oh~ That feels good daddy,” Cadance cooed as she followed his movement along, feeling the hot slab of cock rubbing along her asscheeks.
“And that is only the beginning, how about I give these juicy thighs of yours a ride?” Night Light said with a grin before he pulled back from her asscheeks and put the cock between her thighs, dragging it along her glistening vulva and making Cadance moan.
Night Light then pulled her into his lap, his cock pushing up between Cadance’s thighs as she closed her legs around his dick, enveloping it in her soft flesh.
Night Light didn’t even hesitate as he started thrusting up into her. The friction of those plump thighs sending pleasurable shivers down his spine. Cadance herself moaned along to his grunts as his cock all too teasingly slightly parted her lips every time it was dragged along the wet hot crevice. The heat radiating from Night Light’s cock almost driving her crazy as she smacked her hips into his. Soon enough the pink mare couldn’t take it anymore.
“Come on daddy! Fuck my naughty dripping pussy already! I need it!” Cadance whined, making Night Light chuckle at her teasingly as he stopped his movements and instead lifted her ass up from his cock, kneading into it yet again as he scrutinized it with a lewd grin.
“You really are quite misbehaving. But don’t you worry, I will make sure you naughty filly get just what you deserve~”
Cadance being the horny mare she was tried her best to wait for him to finally take her. She knew that he was teasing her, but she wanted to show her strength and restraint too… At least for another minute… However, what happened next wasn’t something she expected.
The pink mare was confused as she heard a clasp being undone, like Night Light opened a shampoo bottle or something along the lines, making her furrow her brow in confusion.
The youthful alicorn then however gasped as she felt something cold and wet being applied to her tight little pucker. Her daddy’s hands rubbing and massaging lube all around her tight passage.
“D-Daddy! T-That’s t-the wrong hole!” Cadance whined playfully, making Night Light grin.
“I wouldn’t say so my daughter. As dirty as you behave I think this hole is quite fitting. But if you really want for me to fuck your pussy you will have to earn it!”
With that exclamation he lifted her frame up in his strong arms before navigating his flat-tipped rod to her tight pucker and prodding it.
Cadance gasped as she started to squirm a little in need, though Night Light would have none of it as he had to give his daughter a fitting punishment.
He didn’t wait as he lowered her pucker onto his cock, her weight and lube doing the work for him as her ass was spread open easily.
...In fact quite too easily.
“Don’t tell me you let the stallions I hired to guard you ream your ass!” Night Light chided, making Cadance flush slightly.
“I c-can’t help it!” she lightly stutters in her defence, making Night Light shake his head in disappointment.
“You really are a disgrace my daughter. Maybe I should simply disinherit you and then give you to the guards completely as some form of stress relief. At least then you could be useful, seeing as this seems to be your only real talent.”
In that moment he felt her tight ass-muscles grip down on his shaft hard, making him groan.
“I guess a dirty filly likes this idea~” Night Light teased as he used his arms to force his daughter a few more inches down his cock, making the slutty looking mare moan out in depraved bliss.
“AHHHHH~ I-I’m sorry d-daddy...f-for being such a dirty m-mare!”
“As you should be. Your ass is way too loose for a mare of your heritage. Not to mention that with already being spread out by the guard stallions’ thick cocks it isn’t as pleasing as I imagined it once was. Makes me even wonder how you want to earn my cock in your pussy at this rate...”
At that moment Cadance’s horn starts to glow, enveloping his cock and balls, before Night Light suddenly felt them starting to grow. The grown stallion groaned as his rod was not only gaining in length but fitness.
Cadance herself was also writhing from the sensations as she felt her sphincter suddenly stretch out as his cock was spreading her ass further and further apart with each inch of growth, filling her bowels in an all too pleasing manner.
Soon enough the growth started to cease, but it left Night Light with quite the equipment to ‘discipline’ his daughter with. Something that quite pleased him.
“H-How is that, d-daddy?” Cadance finally asks, still dealing with the shocks of pleasure from having her tailhole filled in such a manner.
“Umph, better!” Night Light grunted out, admiring this new tightness that his enlarged tool created, “Though it makes me wonder how you know such a spell as well. Don’t tell me you also fuck around with your magical instructor.”
“W-Well…”
With that Night Light pulled her down, burying his shaft in her bowels completely and inciting a surprised but also pleased cry from the slutty pink alicorn.
“You really are hopeless,” Night Light stated while shaking his head as he stood up with Cadance still speared on his tool, and walked towards a large body-mirror in the room, “Just look at you. Impaled on your daddy’s cock and panting like a bitch in heat!” he stated as he started to thrust into her, getting a loud lewd moan out of her.
“AHHHH~ I-I’m sorry daddy!” Cadance cried out all too happily as she felt his meaty rod pump her insides and spread them apart, “I-I’m simply such a dirty mare! You have to punish me m-more~”
Night Light grinned as he gripped her thighs tighter while he lifted her up, before all too forcefully dropping her down on his meaty shaft again, letting gravity impale the princess over and over again.
Slapping could be heard quite loudly throughout the room, as Cadance’s large plot collided with Night’s hips. The experienced father quite determined to show what happens to naughty fillies like her.
Cadance herself was in heaven. Each time she actually saw herself in the mirror being dropped and impaled on this monster shaft she created. Just to see something so thick and long vanish into her was enough to make her pussyjuices flowing down her cunt and onto the cock that was working away feverishly at her ass.
The naughty mare positively drooled as she was moaning in bliss, and Night Light was not off better seeing how her tight pucker was massaging his rod like a pro, making the cock pulse deep within her, as he enjoyed the pleasurable friction his every movement provided.
Soon enough Night Light felt his climax near, and his movements got only faster, making Cadance cry out and moan all too whorishly in her still all too slutty getup as she was being handled in such a manner.
It proved too much for the naughty mare as she cried out one last time before her juices squirted out like a fountain from her dripping cunt. A whole deluge of her sticky juices splattered against the mirror while Night Light still kept his pace, fucking her in a blur and fighting against the ever tightening ass muscles.
Only moments later he was sent over the edge as well and hilted himself with one last pleased groan.
Instantly Cadance felt his searing hot cum surge from his cock and being dumped into her ass. The feeling of her bowels being turned white alone sent Cadance almost over the edge again, as her cheeks were heavily flushed while she was panting like a bitch in heat.
Night Light then lifted Cadance up from his cock and sliding it along her pussy lips so that her ass rested against his groin area. Said cock was still trashing around and producing cum like a firehose. With a wet splat Cadance’s face got a load plastered all over it. The next few spurts hit her breasts, belly and then it was tapering slowly off her thighs. Night Light was marking his daughter. Marking her to be his property and personal slut.
By the end of it the pink princess had flushed cheeks and was dripping strands of hot sticky spunk from all over her body. She was panting from the sexual exhausting, and leaning back into her father’s chest.
Night Light was panting as well as he walked back to the bed with his now cum-stained and dripping daughter. He dropped her onto it making some of his virile sperm leak out of her ass in a thick wet spurt onto the sheets.
Cadance hummed in satisfaction as she asked while sultrily fluttering her eyelashes, “Did I earn your cock in my pussy now?”
Night Light thought about it for a moment, but then much to Cadance’s surprise answered, “No.”
Cadance was about to utter a confused reply as Night Light continued.
“Seeing as you not only fucked around with a random stallion, the guards, and even your magical instructor you need a bit more...disciplining.”
His gaze went to his messily with his cum smeared cock, “How about you do some cleaning and I miiiiiiiiiiiiiiiiiiight reconsider it,” he said all too teasingly as he swung his still hard and large shaft towards her.
“But daddy! It is dirty!” she tried to weakly protest, but Night Light only smirked at her.
“Not as dirty as you are,” he teased making Cadance pout. Hard. “Besides, it wouldn’t be disciplining if you only had fun. So you better get to it. The way you are whoring your body out I take it you have given head before anyway.”
Cadance couldn’t retort to that, seeing how he had a point. She simply harrumphed in mock offense, but couldn’t help but feel excited about doing something this depraved.
Soon enough she crawled to the edge of the bed, coming face to face with the swaying horsecock of her daddy.
She hesitated only for a moment before she stuck her tongue out and took some tentative licks of the head, gathering his cum from it and licking it slowly clean.
Night Light hummed in approval, before he grabbed her head, wanting to move things along.
“If you want my cock inside of you, you better show some spirit. Or did I raise my daughter to be so slow in performing her tasks?”
Cadance took the offered bait and challenge as she let Night Light guide her luscious cocksucking lips, which still adorned the slutty blue lipstick, to his cockhead.
Night Light shuddered as the tip of his cock entered the warm cavity of her mouth. Said mouth practically drooled over his cum-stained cock as it was driven into her muzzle. Soon Cadance felt it hit the back of her throat, but Night Light wasn’t about to stop his hands, and neither would Cadance as she gulped, letting the thick meat disappear in her throat.
A large bulge was forming in her neck, showcasing the cock this slutty mare so skillfully gulped down.
“Oh!” Night Light moaned, “You really are quite the cock sock my naughty daughter!” he complimented.
A compliment so depraved that Cadance ate it up. Or slurped it up, considering that was what she was doing with his cock.
Night Light soon felt his balls slapping against her chin. Her lipstick glossed lips connecting with his crotch in a wet smooch that showed already on the first connection proof of just how much of a cocklover his daughter was. He quickly enough pulled his length back until only the tip of his cock was in her mouth, drooling pre before lurching forward and starting the facefucking of this pink naughty mare.
The mare simply took it all. Took it like a champ as her esophagus was filled and emptied of this delicious piece of cock repeatedly. She felt the drooling in her pussy intensify as she was facefucked, his musky balls smacking against her chin again and again. Cadance found this oral treatment to be quite teasing to her nethers, while Night Light of course found it quite blissful.
Soon enough his cock throbbed again, but Cadance could sense it too and quickly used her magic to get his hands off of her head and pull herself off the now in her spit glistening rock-hard rock.
It was throbbing and begging to release its seed. The lipstick which was slobbered all over it and especially the blue ring it formed on his crotch were quite the lewd and pleasing sight. A sight which made Cadance’s cunt throb hard.
“Please, daddy!” she begged, “I want you to do it inside of me and not my throat! Please use my dripping cunt and fill it up right with your seed!”
Night Light raised an interested brow, “And what if you get pregnant?” he asked, while Cadance whimpered in need.
“I don’t care! Impregnate your daughter! Breed me if you must! Just please fuck me!”
Night Light grinned as he laid down on the bed. “I think I have done quite enough, though you are welcome to take what you desire my sweet little daughter.”
Cadance didn’t hesitate as she immediately climbed on his hips. Her back was facing Night Light as she used her hands to grip his member and navigate into her needy moist twat. Once she was aligned she didn’t hesitate a second and let gravity take her. The effect was immediate.
Cadance’s mouth flew open as a line of drool flew from her mouth while she let down an earth-shattering scream of bliss. The cock had practically impaled her. Punched right through the entrance of her womb and even against the wall of it, stretching and filling every inch of the princess up so fully and perfectly.
Her juices gushed from her cunt as she instantly came and she felt her legs weakly twitching as she took in all these sensations.
Night Light simply eyed the spectacle with a grin, which turned into a grunt as he felt her walls spasming on his shaft with his balls additionally being drenched in her hot sticky juices. It almost made him want to blow his load into his slutty foal right then and there. Almost.
He simply decided to enjoy this moment as he groped the mare’s juicy flanks, kneading them and helping Cadance out of her slutty delirium with a moan.
“You really are ill-behaved if you keep me waiting like that. But if you don’t want to, I can still pull out and seek your mother. She will probably be more motivated to ride me than you are,” he said teasingly.
Cadance immediately lifted her rear, wet strings of her arousal connecting it to Night Light’s crotch before she pushed it back down with a moan.
“I can do better than her daddy!” she boasted, “Y-You don’t need her! You just need me!”
Night Light chuckled as he continued to fondle her rump, sinking his fingers into her flesh. Cadance took that as a sign to go on and so she did.
Soon the sound of wet squelching reverberated in the room as Cadance bounced her hips onto his cock again and again. Her cunt was being stretched with every thrust, as her daddy did the best to reshape them in the form of his dick, to mark his cock-starved daughter as his own slut.
“If you really mean that, would you even go as far as be nothing more than my personal breeding tool to spread our bloodline?” he couldn’t help but ask as she still continued her wet smacking of her hips against his crotch.
“Yes! I will! I will be your perfect little daughter! Do everything you say! Breed as much foals as you want me to!” she screamed out in blissful confirmation, and Night Light couldn’t help but grin as he took her arms and then continued to meet her wet smacks with his own. His hips driving upwards and hammering against her womb, pounding her inner sanctuary hard and making his daughter squeal and jizz herself in pure unadulterated ecstasy.
“Good!” Night Light said with a grin as he simply fucked her through her climax, not even waiting for her to come down as he built up his own high with each thrust up into her. Each time his cock was stirring up her insides more, making sure she would only feel true pleasure through his large meaty shaft and making her his obedient little pet daughter.
Cadance simply screamed out further, her pleasure almost mind-breaking, her still blue lips in a constant orgasmic ‘O’ of pleasure as her tongue was hanging out of her mouth, making her drool over her own body. Not that she cared as she felt Night Light fuck her right into another orgasm.
“I’m getting close!” he grunted, and Cadance could feel the needy pulses of his thick and hot rod, making her go completely nuts from the sensations as she felt her cunny being speared on it with lightning speed.
“YES DADDY! FILL ME WITH YOUR FOALS!” Cadance screamed out again, shuddering from the intense sensations, just like Night Light did at this point.
“TAKE IT ALL!” Night Light couldn’t help but groan out as he felt his relief wash over him. His balls were contracting, pumping his seed along his shaft and pouring it in copious amounts into her womb.
Cadance spurted a volley of her own juices onto Night Light’s body, another climax hitting her hard and making her tremble from these sensations. Especially as her womb started to extend as Night Light used his modified tool to fill her up completely.
Soon enough Cadance was spurting a visible bump, making her look pregnant, a thought which made her shudder with another electric jolt of pleasure.
“Ahhhhh, I-I’m pregnant…with d-daddy’s foal,” she moaned out before collapsing on him, and letting sweet slumber take her.
Soon enough Cadance hummed in satisfaction as she woke up. She stretched her arms and legs before turning on her side, looking in the pleased eyes of her father-in-law.
“So, how is my little filly doing?” he asked teasingly, and Cadance just grinned.
“Perfect. You know roleplaying is fun. We should do that again sometime,” she then rubbed her still inflated belly, “Almost wants me to actually get pregnant to show off not only my bloated belly but also the paternity mark of my dear daddy using me as his breeding slut.”
Night Light chuckled, “Maybe another time. You are not in season after all. Though it would be interesting if Shining could do the same to Velvet then as well. After all, fair is fair,” he said with a grin, making Cadance purr sultrily.
“My, my. My dear daddy sure has a perverted mind. Not that I would have it any other way,” she said snuggling up to his chest and closing her eyes.
A loud orgasmic scream then drew her attention.
“YES SHINING! POUND YOUR MOTHER IN THE GROUND! MAKE ME YOUR BREEDING BITCH!”
Night Light couldn’t help but chuckle yet again, “Seems like they are still going at it, and the soundproof spell has already run out.”
Night Light then suddenly felt the princess get on top of him.
“Well, in that case we can show them that we are not done as well. Not to mention that you can make me scream louder, can’t you?” Cadance said in a teasing tone, while Night Light felt his groin stir again.
He grinned up at her as he gripped her hips hard, “Challenge accepted, my dear daughter~”
