Restrained

"Fuck, what is taking them so long?" Twilight wonders.

She sits on her throne while rubbing her swollen pussy lips, trying to satiate a burning itch, but it just doesn't want to go away.

"Damnit, I knew it would be too early to take that estrus potion. I need...that cock again."

Twilight's mind wanders as she recollects what happened last night. The throbbing in her cervix remains as she can imagine Cedric's hard shaft piercing through her walls and right through the tight gateway. She can already feel his hot spunk filling her thirsting womb, satiating this torturous, burning heat.

A surge of pleasure rushes through Twilight's body as she approaches climax. She vigorously rubs her hoof around her clit and feels the sensation of release getting closer.

"Fuuuck!" Twilight wails as a surge of bliss finally hits her and a stream of wet mare-juices sprays all over the Cutie Map.

The alicorn sits back and pants in exasperation but not enjoyment. She grimaces as the burning in her crotch returns even fiercer this time. Unfortunately, she doesn't have enough energy to keep staving it off. She needs the only thing that can douse this flame.

The sound of the front door opens, prompting Twilight to sit up straight. A crazed grin spreads across her face as she can already guess who has entered her castle. Before she can get up to leave, Twilight casts a quick spell on the room to clean her mess. The scent of musk and strawberries fade away and not a single trace of alicorn mare-fluids remains, giving Twilight a semi-clear heart and mind as she exits the throne room.

As soon as Twilight spots Cedric and Fluttershy heading down the hall towards her, she puts on the calmest smile she can conjure while her loins continue to drip and burn uncontrollably.

"Hey, you two!" Twilight says with fake enthusiasm. "I'm glad you could make it.”

“No problem, Twi,” Cedric replies. “What’s this little project you need our assistance with?”

Twilight bites her lower lip while her lower region bites back. Her eyes slowly trace down the human’s rigid body until locking onto a bulge in his pants. Clearly, he's been wanting some action, even after what happened last night.

“It’s right inside the throne room,” Twilight explains.

She turns to walk down the hallway with her visitors in tow. Though they can’t see her pained expression, Twilight forcefully tries to keep her tail from swinging side to side to reveal the mess in her privates. The last thing she needs is for her plan to start prematurely or for either of them to back out.

As they enter the throne room, Twilight can already tell the couple are wondering what needs to be done in here.

“Um, Twilight?” Fluttershy asks as they stop in the center in the throne room. “What exactly are we doing here?"

Twilight's artificial estrus is burning bad enough that her mind is about to melt from desire. She can hardly hold on to her thoughts, let alone her plan, long enough for it to fully come true. She turns to face the couple, her face no longer hiding away her lustful hunger.

"Twilight, are you in heat?" Fluttershy asks, noticing the familiar expression.

Cedric looks between her and Twilight as the gears in his brain turn, trying to make sense of the situation until a lightbulb goes off in his head.

"Did you call us here because you need help with your heat cycle?" the human asks. "Why not get Spike or maybe Starlight to take care of it?"

"Starlight?" Fluttershy questions, shooting her mate a confused look.

"She's a pretty skilled unicorn. I'm sure she'd be able to conjure some sort of sex-change spell to help poor Twilight out."

"No," Twilight responds. "I've been bearing with this since yesterday but it's suddenly grown unbearable today. I think it's because I'm a princess that it's become so painful. Spike isn't...big enough to satisfy my urges, Starlight is busy helping Sunburst with something in the Crystal Empire, and I can't just ask a random stallion to fuck me, though, they'd probably enjoy it."

Fluttershy and Cedric look at each other with concern, not for Twilight, but for each other's sake.

"So you called me?" Cedric inquires further. "I mean, I'm willing to help out a friend, but if it's something like this..."

"Cedric," Fluttershy calls, tapping on the human's leg.

Cedric kneels down to the pegausus's level to hear what she has to say, leaving Twilight out of the conversation. The struggling alicorn fidgets with her hind legs, trying to satiate her burning loins but no matter what she does, she can't stave it off long enough. She impatiently waits for the couple to finish their conversation so she can finally get her pussy pounded by that human cock.

The couple look back at Twilight, discomfort and sympathy written on their faces. The alicorn watches in painful desperation as Cedric stands and walks over to her and places a hand on her head. It's gentle and soft, just as she had imagined it would be.

"I'll do it," Cedric finally answers. Twilight looks up at him with overwhelming joy but it crumbles as the human raises a finger. "I just have a few conditions."

"Anything!" Twilight shouts. "Just name it and I'll do it!"

A malicious grin spreads across Cedric's face as he puts a finger up to his chin, "wondering" what his conditions should be. Though, Twilight can tell he's trying to mess with her by stalling and prolonging her insufferable estrus.

"First, we're gonna need some light BDSM equipment," Cedric requests. "I was thinking some rope, a blindfold, ball gag, and a magic canceling ring."

Twilight immediately summons the paraphernalia out of thin air and sets them all into Cedric's open arms. The human looks down at the items with delight and shifts his gaze over to Twilight's expectant, yet nervous face.

"Perfect. Now, maybe a vibrator or sex toy for Fluttershy while she watches?" Cedric looks over at his mate who watches the scene from her own throne. "What do you want, sweetie? Dildo? A double-pronged vibrator?"

"A vibrator shaped like your penis," Fluttershy requests with a smile. "Same size and shape."

Twilight summons the requested toy into the room. It looks just like Cedric's tool, same size and shape, even with skin-like texture instead of silicone. The alicorn hands over the item to Fluttershy who holds onto it for the time being.

"Now then," Cedric says as he approaches Twilight. "Let's get started shall we?"

Although Twilight wants this, for some reason, she's afraid. Cedric's malicious expression and the way he's tensing up the ropes seems too odd, even for light BDSM.

"Get up on the table for me," Cedric demands. "Place your face on the surface of the table and reach your forelegs to your hind legs."

Swallowing an anxious lump in her throat, Twilight does as he commands. She clambers on top of the table in the center of the throne room, spreads her hind legs open, and moves her tail out of the way to reveal her moist, winking, pink pussy. She places her face on the cool, crystal table and tries to reach her forehooves to her hind legs like some sort of exercise.

She looks back to see Cedric tying one rope around her hind pasterns, locking them in place. Two more ropes connect her hind legs to her forelegs, restraining her movement altogether. The thick ropes burn into her skin but if that's what it takes to get bred, she will gladly comply.

The ball gag is placed in her muzzle, muffling any gasps, moans, or cries when she gets penetrated. Finally, a black rag covers her eyes and is tied around the back of her head to obscure her vision and prevent her from seeing what's coming.

Cedric licks his lips as he gazes upon his prey. Tied up and defenseless like a lamb for the slaughter. But he's not going to punish her severely like a monster. He will give her what she wants but it won't come now. He has another area he wants to traverse first.

"Looks like everything is accounted for," Cedric says. "Would you like me to start, Twilight?"

Unable to speak, Twilight nods her head vigorously, begging to be bred.

"Alright, but I have one question for you. How come you're still in heat after satiating it last night?"

Twilight remains silent and a wicked grin grows across Cedric's face as he realizes he's caught her.

"You do realize Fluttershy takes care of wolves, right?" the human asks. His footsteps echo through the castle as he walks around the table like a shark circling its prey. "Those little guys have a keen sense of smell so they were able to tell us that you snuck in last night and took a little bit of my jizz."

Cedric raises his hand into the air and brings it down onto Twilight's rear, sending a sonorous *SMACK* throughout the castle. She yelps in surprise but the ball gag muffles her excitement. A small bit of fluid squirts out from her pussy and dribbles onto the table, soiling it once again in her scent.

"Did you really think you'd get away with something so sinful, Twilight?" Cedric further inquires. "Raping your best friend's mate like that? All you had to do was ask and Fluttershy would have said yes. But no. You had to go ahead and act like a little thief. And you know what happens to thieves, don't you Twi?"

Knowing and fearing the answer, Twilight quickly ignites her horn to escape her bondage and the human's clutches.

"Oops, almost forgot about that."

Twilight's magic suddenly gets suppressed as the magic canceling ring is placed on her horn. She struggles in vain to conjure a spell but the device is blocking her flow of mana. She's officially trapped in Cedric's clutches.

"I'm not a monster Twilight," Cedric begins to explain, "so I'll take care of this 'heat' for you. But I won't be fucking your pussy."

Cedric unzips his pants and drops them to the floor along with his boxers. His stiff shaft springs out into the cool air but the warm blood flowing through it provides it with the strength necessary to stay erect. His hands grasp Twilight on either butt cheek and spreads them apart to reveal her tight, little, purple ponut.

"Truth be told, this is the first time I'm ever giving anal," Cedric says as he traces the small gateway with a finger. "Fluttershy's been willing to try everything besides the BDSM rout and anal and I'm alright with it. I respect her boundaries. But for you..." He places two fingers into his mouth and coats them with saliva. He uses his thumbs to spread open Twilight's anus and gently inserts his digits into the warm cavern. "You've been craving me for some time, haven't you?"

Twilight doesn't try to fight back, neither does she protest as Cedric's fingers dig deeper into her canal. They twist around and run along every inch of her walls, filling her with a new feeling of pleasure. It's completely different from vaginal penetration as it's much tighter and much there's more voluntary constriction. Unfortunately, Cedric immediately pulls out, leaving the alicorn dissatisfied and wanting more.

"What do you think, Fluttershy?" Cedric asks. "Do you think it's slick enough?"

The pegasus flutters over to her mate and Twilight and crawls underneath the restrained princess. A small drop of spittle leaks from Twilight's ass and drips onto Fluttershy's muzzle.

"It might be good enough," the pegasus says. "Make sure you let it all out inside her womb, otherwise she'll keep suffering through her heat cycle."

Cedric nods and positions his rod in front of Twilight's upper entrance. As he presses his tip up against the gate, he notices it's a lot tighter and more resistant than before.

"Just relax, Twilight," Cedric whispers. He leans over and runs his hands through the alicorn's mane, trying to soothe her worries. "There should be enough lube in here to make things run smoothly. I promise not to be too rough with you."

That doesn't seem to edge the princess to relaxing herself but after releasing a pent up sigh, her anus relaxes, allowing Cedric passage. The round spearhead tip of his dick breaks through, sending a shot of pain and pleasure through Twilight's nerves. In almost an instant, the pain subsides and pleasure runs through her body. Her muscles relax as Cedric continues with his movements.

He pulls back and pushes through with violent force, sending jolt after jolt of pleasure through Twilight's body. With each thrust, he forcefully tears through her anal cavity, hilting to the base of his crotch, and filling her with bliss. It's not as painful with the amount of lubricant in her ass. Twilight relaxes and takes the rutting like a pro, allowing all worries to wash away.

"Fluttershy, why don't you join in on the fun?" Cedric suggests.

The pegasus's face lights up as she crawls underneath Twilight and looks up to her dripping faucet. Hot mare-juice leaks from Twilight's cunt, staining Fluttershy's face and filling her with delight. She reaches up and laps away at her friend's flower, tasting the sweet nectar held within. As she pleases her friend, the pegasus plunges the vibrator deep into her own cunt, feeling pleasure far more exuberant than anything so far.

Twilight exhales a joyous moan through the gag as both entrances are being stimulated by passionate forces. Fluttershy's soft, gentle tongue slithers through the alicorn's sensitive labia like a serpent in the grass. It flicks her tender clit, sending shocks of ecstasy through Twilight's nerves, and forcing her to clench every hole.

Cedric's hard shaft keeps ramming deep into Twilight's ass, despite it clenching around him, and tears her apart, but also fills her with joy and ecstasy. He spanks her voluptuous globes, letting them turn from vibrant purple to stove-top red. The pain and pleasure mixing in forms a concoction unlike anything Twilight has ever felt before.

Cedric can feel himself getting close to orgasm. As promised, he pulls his cock out of its current home and reintroduces it to Twilight's burning snatch. Wet and warm like a hot spring; the perfect environment for his seed to be released. This feeling is already integrated into Cedric's mind from before but he feels like he's enjoying it for the first time. Twilight's vaginal walls are having trouble keeping up with with his rhythm as they try to clench and release his cock. However, she doesn't need to do anything as she can feel the rod beginning to pulsate with built up sperm.

Fluttershy unlatches the ball gag from Twilight's muzzle, allowing her screams of rapture to flood the castle as Cedric pierces through her cervix, letting hot human spunk flood directly into her womb. His dick spurts and pumps shot after shot of virile seed, coating Twilight's insides in white and filling her with peaceful bliss.

With his energy drained, Cedric collapses on top of Twilight, burying her under his weight. The human looks up to see Fluttershy approaching him and planting a loving kiss on his forehead for a job well done.

"Was she good?" Fluttershy asks, looking down at Twilight's broken figure.

"She was," Cedric answers. "Though, you know you will always be number one in my book, right?"

Fluttershy chuckles and gives her mate a hug before pulling him off of the busted alicorn and allowing her some alleviation. Twilight rips off the blindfold and looks over at the couple as they bask in each other's love. A tinge of guilt brews in her gut, prompting her to burry her head in her hooves.

"I'm so sorry," she says with shame. Fluttershy and Cedric look over at her with understanding gazes. "I didn't mean to take things that far with Cedric. I was jealous of you two...sharing such intimate moments together and...I wanted to know what it was like to experience the same thing."

Cedric crawls over to the ashamed princess and lifts her head up with his hand. His eyes are calm and understanding, filling Twilight with a sense of peace.

"We're not mad at you, Twi," he explains. "You have to understand that my heart belongs to Fluttershy, that's why we have such intimacy with each other. If I did it with you, it wouldn't be the same. It would be like I'm having sex with a stranger, not my beloved."

Fluttershy joins in and rests a gentle hoof on Twilight' shoulder. "I know you'll find a special somepony soon," she states with confidence. "But until then, would you like to remain as our friend with benefits?"

Twilight looks up at the couple's smiling faces with bewilderment. "First you try to punish me by strapping me down, blinding me, gagging me, and railing my ass, now you want me to join you in your sexual exploits?" she asks. A grateful grin spreads across her lips as she comes to her conclusion. "I'd love to—"

"SWEET FUCKING CELESTIA!"

Everyone turns their eyes to see Starlight Glimmer, Sunburst, and Spike standing in the doorway, jaws digging into the ground.

"S-Spike, everyone, what are you all doing here so early?" Twilight asks.

Spike picks his jaw up from the floor and answers the alicorn's absurd question. "I've been in bed this whole time and I just heard you getting your ass railed into all the way down the fucking hall! How could I not be here so early?"

"I just came back from my trip from the Crystal Empire," Starlight explains in a dead tone. Her eyes remain fixated on Cedric's still-erect cock. "I brought Starburst along because he said he wanted to visit. But...I think we came at a bad time."

"Starlight, if you would be so kind as to purge this memory from our mind," Sunburst requests, "that would be very much appreciated."

The trio leave the room, shutting the door behind them to let the musky group relax by themselves.

"Sooo, that was a yes, right?" Cedric asks, looking over at Twilight.

"Y-yes," Twilight replies.

"Well, I'm glad to be of service, Twilight," Cedric says as the trio head for the front door. "If you need anything, actual help or sexual alleviation, just give me or Flutters a holler."

"Or if you want to join in on some fun next time," Fluttershy adds, "we'll let you join in."

Twilight smiles gratefully at her friends, despite her previous transgressions against them. "Thanks you two. You know, the Gala is only a few days away. Do you plan on doing anything interesting while you're there?"

The couple shoot each other lustful glances and chuckle as a few ideas brew in their minds.

"Oh, we've got plenty, trust me," Cedric replies. "Right now, I need some rest. My balls are already aching from busting too much. We'll see ya later, Twi."

The Ghostbusters theme runs through Cedric's mind, making him put the line "Bustin' makes me feel good," on repeat. Though, with his balls feeling like they are about to be crushed in a hydraulic press after cumming so much in just one day, he can say that if the lyrics were more indicating toward sex, these words would be dastardly lies.

As Cedric and Fluttershy exit the castle, Twilight shuts the door behind them and trots back over to her bedroom. Her womb sloshes around with healthy semen, enough to surely get her pregnant. As she climbs onto her bed and lays down, she rests a hoof on her belly, petting the forming zygote inside, and smiles.
