At first Night Light was panicking, he'd impregnated his own daughter and he had no idea how his wife and son would react to this or if they should even be let in on the big secret. He didn't want to think about it but when he did, it made him realize he was making a big deal out of nothing, he and his daughter had been having semi-regular sex without protection in full knowledge that a pregnancy was possible, incest was somewhat legal even though it was rare that people ever hooked up with their own children or parents and both Night Light and Velvet were fully aware that before Shining Armor had gotten together Cadance, he and Twilight had enjoyed the occassional romp. Night Light relaxed himself and said "So... you're pregnant huh? How do you feel about it?"

Twilight blushed and said "Well, I can't say I'm totally unhappy about it, especially when you consider the countless times I begged you to make me pregnant whenever you were slamming my pussy"

Night Light went "Know the gender yet?"

Twilight shook her head and said "No, though it doesn't really matter either way, if I have a boy then the second he is legal I'm gonna be a responsible mother and give him a nice blow job, if I have a girl then the second she is legal I'm gonna be a responsible mother and cast my cock spell on her so I can give her a nice blow job"

Night Light laughed, Twilight seemed to have interesting priorities about her approach to parenting and how she'd basically be perving on them until they were old enough to fuck. Night Light said "Well, discussions of continuous incest aside, don't you think we should let your mother and brother know about this?"

Twilight rolled her eyes and went "Well of course, how else are we gonna convince them to join in?" Night Light again had to hold back a laugh, his daughter had changed quite a bit ever since they had started taking every opportunity to bang. After making sure that Shining Armor would be available to visit tomorrow, Twilight and Night Light decided to go to bed, though were sure to get some extra fucking in before Velvet got home.

The next morning, the four of them were all gathered in the living room, Velvet and Shining Armor knew there was meant to be some kind of big announcement but were happy to just be spending the morning doing the usual family things like chatting, having a meal together and even watching a Disneigh movie called "Encanter". Midday arrived and it was time for Twilight to deliver the news of her pregnancy, plus the news that she had been having sex with her father for a couple of months and intended to continue that taboo relationship. Velvet and Shining Armor sat down with Twilight and Night Light stood in front of them, feeling slightly apprehensive and nervous, they weren't sure how these two would react and only hoped they would react positively. Velvet was the first to speak and said "So, what's the big news?"

Twilight took a deep breath and went "Mom, Shining Armor... I'm pregnant"

Velvet just shrieked and clapped while Shining Armor went "Wow Twily, that's amazing! Who's the dad?!"

Twilight confidently went "Dad"

Shining Armor, not quite understanding, said "That's what I said, the dad, who is it?"

Twilight shook her head and said "No no no, literally, I mean dad. Dad is the the dad, the father of my child is our father, his grand-daughter or grand-son will also be his daughter or his son. Daddy fucked me, his own daughter, came in my pussy and made me pregnant. Dad is the dad"

The shrieking, clapping and excitement all stopped, the air was still and tense, the joyful atmosphere all of a sudden stone cold dead. Night Light and Twilight waited patiently, stricken with fear of what Velvet and Shining Armor were going to say. Shining Armor processed the information, he couldn't exactly be mad about the incest, he and Twilight had often shared each other's embrace and even recently he had gotten around to claiming his mom's ass, sure it was irresponsible of his father and Twilight to allow this pregnancy to happen but it wasn't exactly like they could undo it. Well, technically they could but abortion was heavily frowned upon, not just in the family but in society as a whole. Velvet took in the facts in much the same way, she knew that her children had fucked each other and she had enjoyed the wonder of anal sex with her son a while ago, she just thought it was silly of her husband and daughter to be so careless.

Velvet was the first to respond as she said "OK... well, when were you two going to mention that you were secretly having sex with each other? Because I'll be honest, the sex I can deal with and, to a certain degree, I can deal with the pregnancy as well. The thing I have a problem with is that you decided you had to do it in secret, why hide that from us?"

Before Night Light or Twilight could answer that, Shining Armor said "Well I actually don't have a problem with any of it, don't be such a hypocrite mom! You literally visited me in secret because you were curious, after years of hearing Twilight sqeauling in orgasm at night, just how good I was in bed"

Velvet blushed and said "I uh... nevermind that then! Congratulations honey!"

Twilight smirked and said "Wow, who'd have thought that we would all end up fucking each other?"

Night Light chuckled and said "Not me certainly, I was fairly content with your mother and I knocked her up twice"

When her husband said that, Velvet had a light bulb go off in her head, she had always wanted a third child and this seemed like a great opportunity to have that wish fulfilled. She turned to her son, Shining Armor, and said "Shining......... make me pregnant"

Everyone just looked to Velvet, stunned and perhaps not even properly registering what she had said, which was confirmed when Shining simply went "What?"

Velvet nodded and went "You heard me, make me pregnant, I want another baby and if your father can impregnate Twilight then you can impregnate me!"

Shining asked "Well then why not just fuck dad? Why has it gotta be me?"

Velvet blushed and scratched the back of her head in embarrassment "Errr... yeah, that's just... mostly for kink factor...haha..." , she laughed awkwardly at how she was basically saying she wanted another baby but wanted Shining Armor to do it because she wanted to indulge in some not-so-wholesome sex in order to make it happen, a lot of wants in one go.

Shining smirked and said "Fair enough, let's get started" as he began to immediately unbuckle his belt to pull his jeans and underwear down.

Velvet went "Wait w-wait... you mean, right here and now?"

Shining freed his stiff member and asked "Yeah why not? Just hop on and have a nice ride"

Twilight chipped in by going "Don't worry mom, me and dad can do our own thing, just pretend we're not here! We promise we won't watch...... too much", Velvet thought for a moment before adopting a wry smile as she started pulling down her jeggings, revealing that she didn't actually have any panties on, seemed like she was planning on using today's visit to take another ass pounding from Shining until the idea of getting pregnant came along. Velvet swung her leg over her son's lap before quickly lining his cock up with her slippery cunt and descending to sink his member into her hot squeezing MILF pussy, the two of them gasped as Velvet began bouncing herself up and down, eager to make Shining blow a thick virile load into her highly fertile womb. While Velvet went cowgirl on Shining, Night Light couldn't help himself as his cock slowly began to engorge, the sight of his wife indulging in some dick was a sexy sight, even if it was his own son who was fucking her.

Twilight saw the obvious bulge in her father's pants and smirked as she rolled her eyes, "Men.." she said as she got on her knees and started unbuttoning her father's pants "Always so naughty and eager...", she pulled down her father's pants and underwear to free the very cock that had impregnated her as she finally went "Just the way I like them" before simply engulfing her father's hard throbbing erection into her mouth and beginning to blow him in earnest. The room was filled with moans of ecstasy, the sound of slurping lips and claps of colliding flesh mixed together to create a symphony of debauchery as they all indulged in the insanity of their taboo union, a family fucking incest fest. It wasn't too long before Shining and Night Light couldn't hold themselves back, thus far the women had been setting the pace, now it was time for them to give in to their urges and take charge in their need to empty their nut sacks and pump their aching members into their respective family members.

Night Light grabbed onto Twilight's head and pushed his cock down her throat, beginning to feverishly thrust away at her face, Twilight just considered it lucky that she'd voluntarily throated her father so much at that point that she had trained herself to supress her gag reflex, even when he placed a hand on her neck to feel the bulge he was creating. Shining had grabbed onto his mom's hips and started thrusting up into her moist cunny, pistoning his hips like a well oiled machine as his balls clapped against the underside of her ass cheeks, Velvet just tightened her arms around Shining's head as she muffled her screams of orgasm into his shoulder. All of them were hot and sweaty as they began to reach their indiviual climactic peaks, Twilight was the first to go as she thoroughly drenched her panties with her fluids, having decided to rub her pussy lips the second she got her mouth lips on her dad's cock. The vibration of Twilight's moans pushed Night Light over the edge as he hilted in her mouth and squirted his thick dick cream directly into his daughter's stomach.

Velvet's folds were still quivering from her previous orgasm when a second one rippled through her body, the constant clenching of muscles that made her vaginal walls milk and massage Shining's cock finally proved too much for him, he groaned through gritted teeth as he held his mom down on his lap and sent a deluge of spunk crashing into her cervix, the perfect cream pie. Twilight let her dad's cock slip out of her mouth and stood back up while he tucked himself away, Velvet remained still on Shining's lap to keep her pussy plugged, she giggled as she felt her son's cock pulsing inside her and said "Shiny, if you get hard again while you're still inside me, then you better believe that I'm gonna ride you until your nuts are drained and your dick is spent... I won't let you pull out without making sure you've given me every last drop of your seed, after all, we wanna make sure I get pregnant, don't we?"

• months later -

It seemed that despite what Velvet had claimed, the first time had been enough to fertilize her egg and soon, both she and her daughter were sporting very round and swollen stomachs as their incestuous children continued to grow inside them. Velvet had a hard time keeping Shining from fucking her again because it turned out he had a thing for pregnant cougars and the rest of Twilight's friends, especially Rainbow Dash, were almost jealous.
