"Cadance!?" Twilight shrieked, covering her modesty with her tail.

"That's my name! You better remember it," Cadance replied, putting the camera into her bag. "You'll be screaming it later."

"What are you doing here?" Night Light asked.

"You, hopefully," Cadance said with a wry grin.

"I mean, why are you here?"

"Uh, I was invited," Cadance said.

"By who?" Shining asked.

"Whom," Cadance corrected.

"What?" he asked, confused.

"Invited by whom," she said.

"I invited her," Velvet said. "Although I wasn't expecting you so soon. What about-"

"Everything is taken care of in the Crystal Empire," Cadance said with a knowing look. "But it sounds like I've missed out on a lot here. Care to fill me in, Velvet?"

"Twilight started a relationship with Night Light. Shining found out about them. He assaulted Night, and tried to blackmail him. Shining got him drunk so he'd have to be on the couch. Then Shining snuck into my room, and Twilight and Night found out about me and him. Things got a little crazy. Twilight got into a fight with Shining, but... As you can see, they've made up." Shining and Twilight both blushed.

"Shining!?!" Cadance scoffed as she walked downstairs. "How could you do that to your own father? You promised. You promised me and your mother that you wouldn't let what you had hurt anypony."

"I know, Cadance. I'm sorry! But you heard Mom, we made up," he said.

"Oh?" Cadance sauntered over to Night Light. "Is this true, Night? Do you feel that things have been resolved?" she asked. He hesitated.

"... Yeah."

"You don't sound too sure," Cadance said. "You don't feel that you've been treated..." she swished her tail along the underside of his chin, "unfairly?" she asked.

"Hrmm, maybe a little," he grumbled. Cadance pulled off the belt holding her bag on and held it to Shining's cheek.

"Sounds like somepony has been a naughty colt!" Cadance said. Shining gulped. He knew Cadance well enough to know where this was going. Velvet put herself between them.

"Cadance, please, there's no need for this!" Velvet said. "We've made up and Shining is atoning for what he's done."

"Oh, Velvet," Cadance cooed, "You were always too soft on him. I remember what he was like before he joined the Royal Guards. And you always did spoil him. Though I didn't realize back then that it was with your own spoils." Cadance ran the belt along Velvet's flank. Cadance turned back to Shining.

"Geez, Cadie. Can't you just have my dad hang me from the ceiling and beat me with a bat like a piñata or something?"

"Shining! I'm surprised at you!" Cadance gasped. "Do you really think so little of your father that you think he would beat his own son like that? You know two wrongs don't make a right." Cadance took a candy from her bag and put it in her mouth.

"I'm sorry." Shining bowed his head in shame.

"Oh, come here, Shiny." She put the belt aside and wrapped her hooves around him, holding his head to her chest. "You made a boo-boo?"

"I did. I'm sorry," Shining said.

"It's okay, Shiny," Cadance cooed. "Cadie's going to make it all better." She lowered her head and took the tip of his horn in her mouth. "Mmm."

"Oh, Cadie!" Shining moaned under her. She bobbed her head a little lower, taking more of his horn.

"Cadance! What are you-" Twilight was cut off as Cadance pulled her mouth of his horn, revealing her ruse. The candy from her bag was actually an arcane inhibition ring that she'd worked securely onto his horn. Before he even realized what was happening, she held him in her levitation magic and sat him down in one of the kitchen chairs she'd brought into the living room. Her magic snaked several nylon ropes out of her bag and tied him securely to the seat. He struggled at his binds but it was no use.

"There now!" Cadance smiled. "The punishment can begin!" she said with unnerving glee. Velvet snatched the stray belt from the floor and put herself between them.

"What do you think you're going to do to my colt!?" she fumed.

"Why, nothing at all," Cadance said, levitating the other kitchen chair into the living room. She placed it facing Shining's chair. "I'll be doing nothing at all to Shining. And that is exactly the point!" Velvet wore a confused expression. Cadance turned to Night Light and motioned for him to sit in the chair opposite Shining.

"Now then. I do believe that it is still Father's Day weekend," Cadance continued. "And we have a father to treat!" Cadance said, rubbing her hoof in Night's crotch.

"Cadance!?" Shining yelled. Cadance ignored him. Even Velvet and Twilight stood frozen in shock.

"And I'll need the help of-" Cadance shuddered, feeling her pussy tremble with arousal. Knowing about Shining's relationship with his mother had given Cadance a healthy fetish for the taboo. Witnessing them consummate the deed personally had been an indescribable sexual high for her. Now she wanted to partake in the act along with Twilight and Night Light. "...his daughter, and her mother." Her wings sprang open in excitement as she felt Night's erection emerge from his sheath.

"Hey, I'm a father, too!" Shining objected. Cadance gave him a stern glare.

"It's true," Night said. "He impregnated his mother and he's Twilight's biological father."

"Uh, uh, UH! STOP!" Cadance cried out as she felt her clit wink. "My wings can only get so erect!"

"And now he impregnated me!" Twilight cried, rubbing her belly.

"UNF! I wish that were so!" Cadance said, feeling herself nearly cum just from Twilight's words. "But alas, I did cast a contraception spell on him. He shan't be impregnating anypony for at least a week. But today isn't about him." Cadance looked down at Night's crotch. Her hoof's busy efforts had brought the stallion to full mast. She released it from her hoof and sidled up onto his lap, facing him. She cradled his face in her hooves, looking at his bruises from Shining. "My poor Night Light. Let me kiss the boo-boo and make it all better." She pursed her lips and kissed him tenderly.

"Cadance!" Shining yelled helplessly from the front-row seat, forced to witness the act. His pleas fell on deaf ears.

Her horn glowed a vibrant turquoise. Her glow wrapped his whole body in her magic. The bruises vanished from his cheek in her cleansing healing spell. "All better." She arched her back and ground her pussy against the base of his shaft, wetting his scrotum with her hot, dripping arousal before she climbed off of him.

"Now, where were we?" she asked nopony in particular as she knelt in from of Night. She took his cock in her hooves once again. "I think, right about here," she purred as she ran her tongue up along the length of his shaft.

"That was in my butt," Twilight said.

"Cleansing spell. Perfectly disinfected," Cadance simply said, giving Night's cock another lick. "With just a hint of minty freshness."

"That would explain the tingling," Night said. Cadance licked her way up his shaft and reached the tip. She opened her mouth, taking the head inside as well as several more inches of him. She turned and craned her neck, looking back as Shining while her mouth was still full of his dad's dick. She was pleased to see that he was visibly angry. Velvet followed Cadance's eyes and noticed Shining's demeanor. She understood Cadance's plan now.

"What's the matter, Shiny?" Velvet asked. "You seem upset to see your spouse with another pony. I thought you didn't mind sharing," she teased. She gave him a knowing look, referring to their many threesomes with Cadance in recent times.

"Hmff!" Shining huffed.

"Oh." Velvet sauntered over and knelt beside Cadance. "Is it because it's another stallion?" Velvet leaned over and began to lick up and down whatever parts of Night's shaft that Cadance couldn't manage to reach.

"Twilight! Do something!" Shining pleaded. Twilight walked past him and knelt down on the opposite side of Cadance. Night Light spread his legs a bit wider, letting Twilight lean in under Velvet to lick and suck on his balls. "That's not what I meant!" Shining fumed. The younger stallion whipped his head back and forth, but the anti-magic ring stayed firmly in place on his horn. He struggled helplessly at the ropes, forced to watch his father get the all-star treatment from the three mares in his life. All three mares had their tails held high, teasing Shining with their exposed marehoods pointed toward him. The combined scent of the mares in heat was tortuous. Beyond them, Night sat in recumbent bliss. His face was the very picture of smug as he looked at his captive son. Cadance lifted her head for just a moment.

"How does it feel to have your balls sucked on by your daughter?" Cadance asked in a sultry tone as her hoof played with her pussy.

"She's actually his granddaughter," Velvet said.

"Oh- FUCK!" Cadance's wings sprang open again, sending the other two mares tumbling to either side of her as she came. "S-sorry!" Her pussy winked and convulsed, spurting her marecum back at Shining's legs. She fell into Night's lap, a quivering heap of a mare overcome by the extra layer of kink to her fetish. "F-fuck me, Night!" she begged.

Night Light lifted her out of his lap and laid her back onto the rug in front of Shining. He moved between her legs and admired her pussy. Cadance reached up and grabbed his horn with her hoof, pulling him into her crotch face-first. Cadance saw Twilight's pussy still dripping with Shining's cum from earlier. Cadance was never one to let something go to waste.

"Twilight," Cadance called out to her, waving her over, "come over here." Twilight walked over to Cadance's head and looked down at her, upside-down from her perspective.

"Yes?" Twilight asked. Cadance didn't reply. Instead she levitated Twilight in her magic and turned her around so that her legs were straddling her head. She reached up with her hooves and pulled Twilight's purple flanks down to her face.

"Cadance! I don't know-ohOHhoHO!" Twilight moaned out as she was made to sit on Cadance's face. Cadance made it her mission to lick every last drop of Shining's cum from her. Her ravenous tongue dove deeply and licked with intensity. It was all Twilight could do to keep herself upright. Velvet recovered herself from her tumble and strode past Shining.

"You're going to have to really step up your game, Son," Velvet purred. "Cadance can eat out a mare like she invented it."

"Mom, come on! Untie me so, uh, you know, you and I can practice!" he said.

"Actually, I bet I know somepony else that needs a bit more practice." Velvet laid down on the floor in front of Twilight, pulling her daughter down to her crotch. Cadance lifted Twilight's hips for just a moment and smirked at Shining.

"Night Light! P-please! Fuck your son's special somepony like he fucks yours!" Cadance commanded. Velvet looked across Twilight's form behind Cadance as Night lifted his dripping face from her pussy.

"Oh, you're definitely a keeper!" Velvet said. Her horn glowed as she used her magic to spread Cadance's pussy open. Night Light righted himself and brought his cock to her pussy, rubbing it along her slit.

"Yes, put it in!" Cadance said. Night leaned forward and aligned the tip of his dick with her entrance, holding it there, adding just a bit of pressure.

"Dad!" Shining shouted. Night turned and looked at him. "Dad, I'm sorry! Don't do it! Please!?" Night didn't move. Velvet's magic held Cadance's pussy spread. And Cadance was all but begging Night to fuck her. Shining realized that this was going to happen, and he wouldn't have any say in the matter. He whimpered. "Be... gentle with her at least?"

...

"...No." Night Light never broke eye-contact with Shining as he pushed, penetrating Cadance at once. He didn't stop, sliding into her in one smooth motion until he hilted.

"Ahhh-ah-ah-ah!" Cadance cried out, feeling Night inside her. He afforded her no reprieve as he pulled back immediately and thrusted into her again and again, breaking up her moan into little choppy cries. She tried to catch her breath. "You weren't kidding Velvet!" she said. "Your hubby's cock really does feel like Shiny's!" Cadance pulled Twilight's hips back down as she resumed licking and sucking her pussy. Twilight could only comply as her own face was pressed into her mother's pussy.

Night Light smiled and looked down at the task at hoof. He watched as his shaft moved in and out of his son's wife. The pink fur of her young body perfectly framed the pussy wrapped around his dick. It felt wonderful. Not just the suede texture of her vagina, or the way her pelvic muscles were expertly gripping him in practiced rhythm. No. It was more than that, he realized. He looked at Twilight and Velvet. The three of them there to please him and each other for him as his son was made to watch.

It felt empowering.

Night felt his balls tighten. Cadance could feel his cock swelling and flare inside her, signaling his impending climax. She wrapped her legs around him, holding him inside as her horn glowed and enveloped his balls in her magic.

"Yes! Cum inside me!" she cried. Night grunted and gave a final push, burying himself into her completely. Cadance could feel his flare stretching her even wider inside as his cock throbbed and twitched. "Ah!" Cadance came again, her vagina milked his cock as he pumped load after load of his cum into her. "Yes! Yes! Fill me up! MMmmm!" Cadance's nose vibrated against Twilight's clit as she moaned, sending her over the edge next.

"Oh my gosh!" Twilight cried out into Velvet's pussy. Twilight felt the knot in her tummy snap free as her abdominal muscles clenched and squeezed the last of Shining's cum from her, gushing along with her own marecum into Cadance's waiting mouth.

Velvet was the only one left in the lurch. But Twilight could hardly have been expected to be at the top of her game with Cadance distracting her so much. But she took it with a mother's grace and just cradled Twilight head in her lap while she recovered. After a moment, Twilight looked back and saw Night still inside Cadance, even as his cum was beginning to leak out of her around him. Twilight stood and stepped backwards over Cadance, pointing her marehood at Night. She laid down on top of her former foalsitter, bringing her pussy against hers, as close to his dick as she could.

"It's my turn!" Twilight whined.

"Twi, baby," Night Light panted as his softening penis began to slip out of Cadance. "I need a few minutes."

"No you don't," Cadance said, enveloping his stallionhood in her magic. Night Light saw himself come back to full mast right before his very eyes. It was rigid as a steel rod, as though he hadn't cum in weeks.

"Ngh! What did you do!?" Night grunted.

"I just eliminated your refractory period," Cadance explained. "So now we don't have to wait for you to be ready again."

"Daddyyy!" Twilight moaned insistently.

"Okay, okay!" Night Light placed his hooves on her flanks and reared up to mount her from behind. He felt somepony's magic help to guide his aim. He pushed his hips forward to her magically spread lips.

"YesYesYes!" Twilight squealed, feeling him press at her entrance. Despite her young tightness, he easily penetrated her with the aid of so much lubrication from... everypony. "Yesssss!" Twilight hissed as she felt him slide inside her. Under her, Cadance wrapped her hooves around her in an intimate embrace, holding her as she was getting rutted.

"Is this seat taken?" Velvet asked. Cadance looked up at the mare standing over them.

"Just a sec," Cadance said, squirming a little out from under Twilight until her face was resting on Cadance's lower abdomen. "There. Lots of room."

"Perfect," Velvet purred, turning to squat on Cadance's face. "I hope you can give me an encore of your performance with my daughter."

"Certainly! I'd be more than hapimmff-" Velvet sat on Cadance's mouth. Velvet turned and looked back at Night Light, happily pounding away at Twilight behind her.

"Mmm, just like that, Cadie" Velvet hummed, feeling her expertly licking at her pussy. Velvet ran her hoof through Cadance's mane as her eyes listed over at Shining. "You really need to step up your tongue game."

"Hmff!" Shining huffed.

"Oh my gosh!" Twilight cried out, feeling Night's balls slapping against her swollen clit with each thrust. "Daddy! Daddydaddydaddy I'm cumming!"

"Oh, fffu- yes!" Night growled, feeling her pussy squeezing him as she came. "Oh baby! Daddy's close too!"

"Yes! Do it inside! I want to feel you cum inside me!" Twilight moaned into Cadance's fur. Night light felt his balls tighten and his tip flared again, stretching her.

"Ngh! Okay baby, here it comes!" He grabbed her hips tightly and pushed as far as he could as the first load shot deep inside.

"I can feel it!" Twilight squealed with joy as she felt him pumping his copious volume into her, filling her quickly. "There's so much!" she cried, putting a hoof to her belly as she felt it being pumped deeper into her. Night Light's legs gave out as he nearly fell backwards, pulling out of her with a wet 'plop'.

"Whoa there," Velvet said, catching him with her magic. She stood up and looked down at Cadance between her legs. "Cadance dear, a commendable effort. But I think I know what I need to finally get off." She motioned to her husband's limp penis. "Oh, do you mind?"

"Sure thing!" Cadance said, casting her spell on his penis, getting it fully erect once again.

"Velvet, no-" Night Light whined.

"I guess making you watch all that makes up for the sex," Velvet said to Shining. "But as for you attacking him-" Velvet swung Night Light in her magic toward him, causing his erection to slap Shining's face, leaving a sticky smear. "A slap on the cheek will suffice."

"Ugh!"

"Velvet, I'm too tired to go again! Please just bring me to bed so I can rest," Night begged. She carried him upstairs.

"That's alright dear," Velvet said. "You can just lay there and I'll do all the work." Night Light gulped as she carried him into their bedroom and locked the door.

"Can somepony untie me now?" Shining groaned.

"Alright. I guess you've gotten your comeuppance," Twilight said, cutting the roped with her magic and taking the ring off of his horn. He got out of the chair and stretched his limbs before settling onto the couch.

"So, Twilie, Cadie... I'm a little 'worked up' after seeing all that," Shining said. He patted the cushions on either side of him, inviting the mares. Twilight straddled his lap and licked his face.

"Mmm, still tastes great!" she said. Shining was about to put his hooves on her hips and pull her closer. Twilight got back up again. "Actually... this whole experience with mares has gotten me more curious. So I'd actually like to spend some more time with Cadance. Maybe I'll catch up with you later?" Cadance followed Twilight up to her bedroom and they locked the door.

"Okay," Shining said to nopony. "I guess I'll just be here on the couch. By myself."

Shining Armor, and his father, Night Light, were both hard at work at the stove cooking dinner.

Cadance, Velvet, and Twilight all sat around the kitchen table. The heavily pregnant mares each looking like they had swallowed a whole watermelon.

"I still don't understand how this could have happened!" Twilight said. "Did your contraception spell fail?" she asked Cadance.

"No. It's a textbook spell. I've done it plenty of times," Cadance defended.

"It has to have been Shining," Velvet said. "He and Night Light are the only two stallions we've been with. And Night has had a vasectomy."

"The vasectomy! That's what it was!" Cadance realized.

"What do you mean?" Twilight asked.

"It must have been when I used that spell for Night's bruises! The Heal spell must have healed everything."

"Cadance! You're pregnant with my dad's foal!?" Shining gasped.

"We all are," Twilight said.

"Wow," Night said. "Just a few more and I'll have my own hoofball team!"

"DAD!" Shining yelled.

"What? You knocked up my wife. I knocked up yours! So now we're even," Night said as he stirred the food in the pan. "I raised your daughter for years. So now it's your turn."

"Shinyyy!" Cadance whined, "I'm horny again!"
"Me too."
"Me three."

Shining gulped. Night put a hoof on his shoulder.

"And Son, you and I are going to have to work together as a team if we're going to have any hope of keeping three horny, pregnant mares satisfied."
