"Here you go, it's a beautiful little filly," Nurse Redheart wrapped up the little one before Rikin took her and lay her to rest in Twilight's forelegs. The little one was definitely a cross of pony and griffon, having the hind end of a pony and front end of an avian. Tiny feathered wings sprouted out of her back and a stub of a horn protruded from her head. Such a perfect mix wouldn't have even been possible without magic, and it was the only one of her offspring so far to have both wings and a horn.

"She's like none other," Twilight said proudly.

They shared a few minutes with the little one before it was finally time for her to leave for a complete checkup. Even if Twilight had already checked for anything, she allowed her to be taken for the official check. She had other things to do and didn't want the little one present for them.

"Hand her off to the others and then return, please," Twilight said to Redheart as she was leaving. The nurse nodded somewhat nervously.

"You're not already having naughty thoughts are you?" Rikin asked after Redheart was gone, "I'd think you'd be a bit worn out."

"Oh it wasn't that bad," said Twilight, "A nice elasticity spell can go a long way. It actually felt a bit nice."

"Feeling riled up then?" Rikin grinned, "I wouldn't mind nailing Redheart's plot either."

"Mmm hmm," said Twilight, "Just you wait."

Nurse Redheart returned, slipping into the room and closing the door again. She somewhat reluctantly came back over to the pair where Twilight still lay on her back with legs splayed.

"Um, hello," said Redheart, "Is there something else I can help you with?"

"Mmm, yes," said Twilight, "Could you reach a hoof up in there and feel around? Just to be sure nothing is loose in there."

Redheart tilted her head, pausing for a moment, but not daring to disobey the Queen. Perhaps she just wanted a bit of fun after all. Redheart pushed one of her front hooves to Twilight's cunt and pressed in. It was loose enough to get into easily, but still elastic enough to stretch nicely over the hoof as it was pushed further.

"Um, everything feels okay," said Redheart.

"The other hoof too," said Twilight, "I need another stretch to cool down."

"Um, of course," Redheart nodded slowly.

She pushed her second hoof next to her first, pushing slowly and gently as it popped in next to her first hoof. Unsure of what to do, she thrust her hooves slowly a few inches, alternating them. Twilight chrred at the wonderful stretchy penetration, but her grin turned sadistic.

"Remove them," Twilight smirked.

Redheart pulled at her hooves, but they didn't budge. She pulled as hard as she could, straining her whole body, and it still wouldn't come out. In fact, they were being slowly sucked deeper into Twilight's sloppy cunt.

"I-I can't..." Redheart looked up at Twilight, and her heart sank when she saw the sadistic gleam in Twilight's eyes, "Oh please don't... I've always done what you wanted, please don't."

"And you'll keep doing what I want, you mud pony slut," confirmed Twilight. The feeling of power she got as she murdered an innocent on a whim never got old.

Rikin didn't take long to take advantage of the stuck pony either. He moved up behind Redheart, grasping her hindquarters and pulling himself up to her. He pushed his cock against her sleek unwilling fuck hole, pushing it in firmly. She grunted as she felt his thick shaft stretch out her soft pussy, his claws digging against her flanks as he pushed deeper and began to thrust rapidly.

Redheart pulled back as hard as she could, thrusting herself back against Rikin unintentionally, her whole body shaking with panic as her forelegs were pulled in up to the knee, then gradually further. Soon the hungry cunt lips were wrapped around her upper legs, forcefully sucking her head as well. Rows of tiny teeth seemed to grow out of Twilight's inner tunnel and dug into Redheart's flesh. Redheart thrashed, her nurse hat falling to the floor as she tried to avoid her head going into the sopping wet cunt-mouth.

Rikin rammed harder, penetrating into their victim's womb and continuing to hammer his shaft into her. He rammed her whole body against Twilight with each thrust, then reached a claw foreward to shove at Redheart's head, pushing it into Twilight's and grinning as the toothy cunt lips slid over the pony's face. Redheart let out a sobbing scream which was quickly muffled by Twilight's inner flesh, and the vicious lips slid further down her torso.

Twilight groaned out as her pussy was stretched far wider than it had when she gave birth, rolling her hips lustfully against the pony and spreading her legs out widely to allow Rikin to fuck the whole mare into her. Rikin groaned as well, arching his back and digging his claws deeper until blood flowed freely down Redheart's legs. He fucked her violently, shoving her an inch deeper with each thrust, watching as his wife's pussy swallowed her whole.

As the lips pushed up to Redheart's thighs, Rikin moved his claws from her hips to Twilight's hips, rolling his hips in time with her own. He squawked as his orgasm rushed through him, blowing his load into the nurse as her hips were being pulled into Twilight. He pumped half of his orgasm into Redheart before she was sucked too deep and slid off his cock, then the other half in Twilight as he continued to thrust.

Nurse Redheart was pushed up into Twilight's womb, stretching out Twilight's belly several times as much as her pregnancy had. Her swollen belly churned around her victim, then suddenly all of her muscles tightened and compressed. Magical energy shot through Redheart's body as she was crushed, her bones beginning to snap one at a time. Her legs were crumpled up against her, her ribs began to fracture then, and finally even her skull cracked with a loud pop. Redheart let out one last bloodcurling scream before her lungs were crushed, her whole body compacted.

Twilight's body continued to churn after Redheart was dead, grinding her corpse into pieces, the magical power breaking it down more and more. It only took a few more minutes before her victim was nothing but bits of flesh and shards of bone.

Twilight groaned, "Have a drink, dear..."

Rikin slid down between her legs, opening his maw and lapping his tongue against her pulsing labia, cupping his beak against her as good as he could. Once he was in position, Twilight released the load inside of her, the red slop that was once Nurse Redheart splattering out of her pussy. Rikin dutifully gulped as much of it down as he could, even as much of it escaped from the edges of his beak and formed a thick puddle of mush on the floor.

Once done, Twilight panted, "That just made me kinkier I think. Hm... let's go visit my folks. They're probably visiting the little one as we speak.

Sure enough Twilight's parents, Twilight Velvet and Night Light, were busily paying attention to their granddaughter. Twilight came into the room, and without any explanation, grabbed each of them by the head and turned them towards the door. She slowly dragged them as she went back outside, guiding them towards the waiting room.

"I see you got to see little Twilight Shine," she said matter of factually, "But I need to borrow you for a bit, if you don't mind."

Her parents weren't unused to Twilight grabbing them by the head or legs to lead them places, so she didn't think much at first.

"Oh um hello dear Twilight," said Velvet, "Oh yes she is so beautiful."

"Just as cute as you were," said Night Light amiably.

"Oh you two are so nice to me," Twilight said, their innocence turning her on, "Mmm, you're making me wet."

"Pardon?" asked Velvet.

Twilight didn't answer immediately, but dragged them out to the castle gardens where she'd have plenty of space and could feel the sun on her as she did her thing. Ignoring the other ponies enjoying their day there, she chose an open place and led them there. She then pulled Night towards her, shoving Velvet over towards Rikin, who grinned widely at the offer.

"Wh-what's going on?" asked Night.

"Oh nothing much," said Twilight, "I've just noticed that the two of you don't really get into well.. the things I do like Shining does. You probably think I'm a monster."

"O-of course not I-" Velvet was cut off.

"Oh you're right. I am a monster," said Twilight, "And if you were monsters too, I might have allowed you to carry on as you were, but that's just not the case. So I decided I'm going to kill you, Daddy. Then I'm going to use you, Mother, as another brood mare."

"B-but I'm your father..." was all Night could think to say.

"You think you get special protection because you fucked me into Mom's cunt?" Twilight responded, "No, you don't. I'd kill anyone that was no longer amusing to me if I was horny and they were conveniently present."

"Am I amusing?" asked Rikin.

"Are you alive?" asked Twilight, "Then I guess you are. Actually you're the biggest monster I know besides myself."

"You say the most romantic things," smirked Rikin.

Twilight grabbed her father again by the neck, twisting him and slamming him back down onto the ground hard enough to indent the ground. He cried out and writhed about in her magical grasp as she forced his legs apart and slid herself over his belly to straddle him cowgirl style. She rubbed her drooling cunt against his shaft, leaving a glistening layer of goo on his shaft, before pushing her entrance to his tip. Twilight slid down as she gracefully impaled herself onto the cock that made her, and her father clenched his eyes shut as if not looking might make her go away.

Rikin meanwhile grabbed Velvet by the neck with one claw and pushed her onto her back as well. He dug his claws into her neck until she gagged, tears rolling down her face which were lapped away by the wicked griffon. He slid his other claw down her belly, feeling of the milf's pussy, sliding several fingers inside before reaching down further and probing at her ass. The tail hole felt like it might be virgin, so he pulled his shaft down to her tailhole and pushed hard against it. He forced his unlubricated shaft into her plot, causing her to cry out and arch her back against him, and began shoving himself deeply.

"Oh Daddy you're so hard," teased Twilight as she began to roll her hips against him, impaling herself womb deep as her pussy milked the shaft within her, "Naughty Daddy, getting so hard in your daughter's pussy." Her horn glowed, fully healing up her insides, which tightened around his throbbing shaft and rolled up and down the length more firmly. Casting a fertility spell, she made sure that she would be ready to accept the incestuous seed. "Come on now. Cum hard in me, I want to milk that fertile seed out of you."

Night Light glanced over at his wife as if to see if she was looking his direction, then slid his forehooves down to grasp at his daughter's rolling hips. Deciding he may as well enjoy the moment, and perhaps hoping enjoyment would cause her to spare him, he began to roll his hips back in response, increasing the wet sound of their penetration with his movements as their bodies slapped together. He opened his eyes and looked up at her, tongue panting out the corner of his muzzle.

"Oh Daddy," cooed Twilight, speeding up her motions along with him, pulling her hips almost all the way off his shaft before slamming them back down onto the incestuous cock, "You've wanted this for a while haven't you. Come on, let me hear you say it."

"I.. I wanted this," Night said as if hoping Velvet wouldn't hear. He gripped her hips more firmly and raised his head up to offer a kiss.

Twilight accepted the kiss, batting her tongue around with her father's and drooling down his throat, then pulled back, "Louder. Make sure Mom can hear you. Tell Mom in explicit detail about how you've always wanted to fuck a foal into me." She squeezed him harder; it was amusing to see him try to bribe her out of killing him.

"I..." Night could barely speak now with his cock throbbing hard inside her, "Velvet sweetie," he said more loudly, facing his wife, "I've always wanted to knock up Twilight's amazing pussy. I want to stuff my foal batter deep into her womb and fuck a foal into her just like I fucked her into you."

"Oh fuck yes," Twilight groaned as she rolled her eyes back. Her pussy suddenly exploded in bliss around Night's shaft, flooding hot juice down over his cock and splattering it out to drool down his thighs and puddle onto his belly. Her ready cunt milked him desperately, begging him for his seed, and it didn't take him long to give it. He cried out loudly as he creamed hard into his daughter's fuck hole, flooding her womb until her belly swelled up slightly, the excess splattering out from the tight penetration as well.

As her motions slowed down, Twilight leaned closer and exchanged another kiss with her father, "It's so hot to let you pound me pregnant, but unfortunately for you... that won't stop me from killing you." She pulled her cunt off of him with a long slurp.

Rikin was quite content to continue boning Velvet's hot little plot as he watched the special father-daughter moment. He rammed himself deeper until his belly slapped against her pussy with each thrust, thick cock stretching out her anal passage and dragging back at an angle so that his barbs tore against her sensitive inner walls. He moved both his claws to her hips, digging his claws into her and groaning as he listened to the sweet sound of her sobbing.

"From the first time I saw you, I knew you'd be a hot rape," said Rikin between lapping at her face, "You better get used to my cock, because you're going to have it ball deep inside you an awful lot from now on."

"No please.." was all Velvet could get out, "Mercy..."

Rikin chuckled, "Mercy? If it were up to me, I'd gut you on the spot and pour your innards over my head as I feasted on you. You're lucky Twilight wants to keep you as a fuck slave."

Rikin pulled her rump up off the ground and drove his cock down into her harder. Hammering into her pile driver style, his movements grew faster as she was further lubricated by blood and pre. She was about to beg more, but froze with her muzzle half open when Night started telling her how he wanted to fuck a foal into their daughter. She blushed from head to hoof and grew dead silent.

Rikin laughed at the response, but not for long as he wasn't far away from his own orgasm. He finally blew his load into her taunt little ass, pumping her gut full of his seed, packing it deep as he dug his claws deeper into her. He finally yanked himself free, allowing her rump to flop onto the ground. She curled up into a fetal position and began to sob again.

"Make her watch, Rikin," Twilight spoke to her husband, then after making sure he did so, she looked back to her father, "Ready? This is gonna be... weird, but I think it will work out poetically. First things first though, I want your horns for my collection."

Twilight horn glowed with dark magic and her telekinesis twisted at her father's horn. He cried out as the energy dug into his head, slowly prying his horn loose and twisting it away. It came free with a gruesome pop, blood splattering as it was pulled out by the root, nerves hanging from the bottom and leaving a bleeding hole in the top of his head. He cried out and curled up on the ground much as his wife was doing. Of course her mother received the same treatment, rending her horn away from her and leaving a gash in the top of her head. Leaving her mother to sob, she took the horns and put them aside for later.

Her horn glowed again and her gender shifted, forming a thick sheath and massive balls hanging down beneath her. Her cock spilled free of the sheath, growing thick and long, hardening within seconds. She sat back on her haunches, and smacked her fathers face with her cock tip.

"Suck it." Twilight grinned down at him.

Perhaps hopeful that she wasn't killing him yet, Night didn't hesitate to kneel all four legs to lay on the ground in front of her, still clearly dizzy and in pain from his horn removal. He reached his forelegs to stroke down his daughter's thick shaft and slurped at the tip, lapping about it. He let out a confused squeak though as his tongue was caught in her urethra and sucked inside.

In confusion he tried to pull his head back, only for Twilight to put her forehooves against the back of his head and pull him closer. He yelped as her cock slurped in his muzzle much as her pussy had slurped up Redheart earlier. Twilight purred in pleasure as his muzzle was sucked in fully, his eyes looking up at her and begging for mercy one more time before they were covered by her fuck flesh.

At that point he panicked, trying to push himself back away with both forelegs, but Twilight grabbed them with her magic and forced them down against his sides. The hungry flesh slid over his head, slurping him in up to his neck as her cock swelled from his size. Twilight groaned, straining and rolling her eyes back as it forced its way over his shoulders, then began to suck his torso into the fleshy cavity.

By the time it got down to his belly button, his head was pushed into her ball sack, the magic allowing the sack to swell with his size. He began to be sucked in rapidly then until soon only his legs were outside, kicking frantically and trying to pull himself back. Twilight took a deep breath to concentrate, and stuffed the last bit of his legs deeply into her. Stroking herself as she felt the last of him flow through her, soon his entire body was curled up within her ball sack.

Dark magic swelled over her overgrown sack then, and suddenly it was alive with Night's thrashing as the magic burned into his flesh. He howled out in agony as his flesh was literally eaten off his body, fur and skin dissolving into white goo. Just as her magic had turned Redheart into slosh, he began to literally melt into cum. He let out one last howl, breathing in a thick mass of spunk that used to be him, and then shook violently in his deathgasm as he finally was given rest.

Twilight moaned loudly, slowly stroking her shaft and straining not to get herself off too quickly. "R-rikin... the fountain..." Twilight dragged her massive balls over to the fountain in the center of the garden, then used her magic to flush the water out of it, emptying the fountain of all fluid before looking back to her mother. Her magic grabbed hold of Velvet, dragging her towards the fountain and depositing her inside on her back.

"Spread those legs, slut," said Twilight, "I'm going to fuck Daddy into you. Do it right now or you'll be joining him."

Velvet shook violently as she lay on her back within the fountain, but spread out her hind legs and braced herself. Twilight pressed her tip against her sobbing mothers rape hole, pressing the tip hard against her cunt. It stretched her wide as it popped inside, and Twilight went womb-deep on her first thrust. A few more hammering thrusts and she broke through her mothers bruised cervix to enter her womb as well.

"Oh yes, you have no idea how awesome this feels," said Twilight. It was a weird awesome, but amazing all the same.

Twilight pushed her cock until it stretched the back of Velvet's womb, swelling her mother's belly with the size of her cock already. She began to hammer into it, stroking the base that wouldn't fit with both her forelegs as she continued to rotate her hips.

"Beg me for it," said Twilight, "Beg me to fill you up with Daddy. Tell me how much you're glad he's dead. Beg me for it, slut!"

Terrified, Velvet followed her order without question, "P-please do it. I-I'm so glad he's dead, please fuck him into my pussy like the cum whore I am so I can bear your incest babies!"

Twilight groaned out loudly as she finally let herself loose. Cum surged up through her cock, her whole shaft swelling with the size of the load before blasting it into Velvet's ovaries. Her mother's womb swelled up like a tight balloon, and the remainder began flooding out from around the penetration.

Velvet's womb would have popped had Twilight kept inside a moment longer, but she yanked out and began hosing Velvet down with her juice. She covered her with thick seed, flowing off her body and bathing her. As Twilight's balls began to shrink, the fountain was filled with her father's white, gooey remains, sperm splattering up into the air and raining back down upon Velvet. Velvet gagged as she accidentally breathed in a flood of sperm, shutting her eyes tight as the seed burned into them. Finally empty, Twilight pulled herself out of her mother with a lewd slurp.

"That's it, bathe in the remains of your dead husband," Twilight teased, "Drink it, and don't stop until I tell you to."

Velvet could barely make out what Twilight had said, so took a while to respond, but slowly turned herself over. Her whole body was coated completely, unable to make out any part of her through the thick mess that was raining down onto her. She lowered her head and began to drink the best she could, though several times she hurled seed back up into the fountain. Terrified of what might happen if she stopped, she continued to guzzle even then.

Twilight lowered her head as well, stepping into the fountain and flexing out her wings to feel the spunk wash over her. Showering herself, soon she was covered just as much as her mother. Rikin even moved into the fountain as well, laughing as he let his own thick feathers be covered with the gooey remains. The three of them writhed, rolled, and squirmed inside the hot mess for another half hour, until all their bellies were swollen with seed.

Finally Twilight felt sated for the day. She pulled herself out of the fountain, cleaning herself off with her magic and splattering the mess that covered her back into the fountain. Rikin was similarly cleaned, and the two went back to nurse and visit with their new child once again. Velvet was dragged to Celestia and Luna's floor, where she was chained up with them to begin her new miserable life as a breeder.

Twilight looked forward to training their new child in all the best ways to subjugate and rule, and to knocking her up once she was old enough. Life was good.
