Punished With Pleasure

Twillight laid back on her bed in her darkened room. All the windows were closed. The door was locked and Spike had been sent out with twenty bits and carte blanche to use it as he saw fit. The soft, linen sheets comfortingly caressed her as she sank into them. Two sandalwood candles spread a sweet scent over the library and cast a warm glow throughout the room. The flames flickered, strange shadows spreading on the walls.

The room was absolutely silent. Nothing to distract her. She pulled a lavender blanket over herself and spread her hind legs. Her cuny was already dripping wet with anticipation of what was to come. The unicorn chose to tease herself, first stroking her teats, flicking and running her hooves over them. She had never cared much for toys. She preferred the gentles caress of her own hooves. Slowly, tantalizing slowly, she reached down and traced one hoof around her outer lips. Her marehood began to open like a flower. Twilight spent a few seconds tracing her hooves around the opening of her vulva before moving it to her clitoris.

Once she located her clitoris, she began softly stroking it, moans escaping her lips. She removed her hoof from her clitoris and went back to tracing her outer lips. The teasing was almost more than her body could bare. She arched her back as a wet spot formed on her bed and a louder moan escaped her throat. She moved up to her teats, rubbing them.

Twilight moved her hooves up and down, from her teats down to her clitoris. She added another hoof and, at a glacial pace, traced her clitoris with both of her hooves. She closed her eyes, waves of pleasure coursing through her body. Her marehood was drenched as Twilight ran her hooves in circular motions. She could feel herself getting closer to her peak. Wanting to prolong this experience, she removed her hoof from her clitoris and began rubbing her teats with one hoof and her labia majora with the other.

Every few seconds she would stroke her pleasure button then go back to her labia, tracing circles within the sensitive flesh. "Oh, oh..."

Waves of pleasure nearly drowned her consciousness. Her every sense was focused on jolts of ecstasy surging through her body.

She barely even noticed as her door opened.

"And what do we have here?"

Twilight's eyes shot open as she jumped up from the bed. Standing in the doorway was none other than Princess Celestia. Her white coat seemed to glow in the orange candle light. Her large, white wings were spread to their fullest extent. A grin played upon her muzzle as her pastel mane blew softly in its ethereal wind. Her hoofsteps were silent as she trod up to the bed.

The unicorn rushed up to her marefriend, greeting her with a nuzzle. "P-Princess! You're back from Griffhalla! I'm so happy to see you!" Then, she realized the position she had been caught in. Her elation turned to embarrassment as a crimson blush covered her face. "Um, oh, I mean, I, I g-got lonely waiting for you to come back and, and you were gone for a really long time, too long, and you wouldn't believe just how much I missed you and-"

The torrent of excuses were cut off as Celestia pressed a single hoof to her lover's lips. She nuzzled the smaller pony. "Shh, shh. None of that Twilight. I will not have you apologize for a perfectly natural urge."

Twilight looked down to the floor. "I really missed you. Everything about you. Our weekly tea-time and study sessions. Your smile. Your laugh. The way you eat cake. Everything. I didn't realize how much I'd miss you."

Celestia spread her wings, wrapping Twilight up in them. Twilight leaned into her as she ran a hoof through her mane. "You silly filly. I missed you too. I missed your laugh and smile and that adorable grin you get when you've figured out something and you just look so darned pleased with yourself."

Twilight pressed her muzzle against her coat, drinking in her scent. Celestia always smelled of the summer. Grass and lemons and, for some reason, the nearly imperceptible scent of clover. All of those elements made up the Sun Princess's scent. Twilight loved it. To her, it was the most beautiful scent in the world.

Celestia lifted up Twilight's head. "I must admit to being disappointed in my pet, however glad I am to see you. I missed you so much I rushed right here to surprise you the minute I got back. And what do I find? My dear pet in a shameless display of wantonness, squealing like a lustful filly in heat. Not proper behavior for a Princess' pet."

Twilight's ears folded back even as her loins tingled. Celestia laid her hoof on Twilight's cheek, comforting her even as she scolded her. "What do you have to say for yourself? You promised me you wouldn't even masturbate till I got back, that you would save yourself for your Mistress."

Twilight gulped as the full realization of what she'd done struck her. Panicked, she wrapped her hooves around Celestia's neck. "I'm sorry! Please don't leave me!"

Celestia blinked. "My dear, darling Twilight. Why on earth would I leave you?"

"Because Pinkie said that the fastest way to lose a friend is to break a promise. I know that must apply to marefriends too! I'm sorry, I just got so lonely. I'll never break a promise to you again!"

Celestia leaned her head back and planted a long, loving kiss upon her lips. "Take anything Pinkie says with a grain of salt. Yes, it is wrong to break a promise to a friend. But there are mitigating circumstances here. You made the promise while you were drunk. It was a foolish promise anyway. No nineteen year old mare can honestly be expected to refrain from self-pleasure. Why, I did it multiple times a day way into my hundreds. Before and after every Parliament meeting. Took the edge off."

Twilight's blush deepened as she thought of her marefriend laying on a bed, her hooves exploring holy regions. Her thoughts were dizzied, feverish with the last lingering feeling of Celestia's lips on hers.

Celestia kept her head tilted so that Twilight was staring up into her violet eyes. "And mistakes can be atoned for. My little pet must be disciplined, that's all."

Celestia traced her lips from Twilight's lips to her cheeks, to her neck and then she suckled the skin of Twilight's throat. Twilight shivered, her body still sensitive from her self-exploration session. Celestia ran more little kisses from her throat and then back onto her lips. "What should Mistress do with her naughty, naughty little pet?"

Twilight whimpered and jerked as Celestia lit up her horn and explored her folds with her magic. "Maybe her little pet should be spanked?"

Celestia grinned. "Yes, I think a good rump warming is certainly in order."

Golden magic took hold of Twilight's ear as Celestia led her over to the bed. She bent the unicorn over her right knee so that Twilight was between her legs and Twilight's stomach rested in a way that made her bottom stick out.

Celestia did not begin the spanking right away. Instead, she massaged and fondled Twilight's rump, stroking the plump purple posterior. After a few seconds of this treatment she lifted her hoof and brought a light slap against Twilight's behind. Twilight jumped. The slap was light, but left a sting in its wake. The princess brought a second slap across Twilight's rump in the same place, waited a few seconds and landed a third spank. Twilight panted as the Princess landed a fourth spank. This spank was harder than the others. The fifth spank was the hardest yet. Her bottom jiggled with the sixth spank, the supple flesh of her well-toned, upturned rear rippling beneath the firm smack.

The seventh spank left a pink mark against her chastised backside. Celestia fell into a rhythm, the eight, ninth and tenth slaps falling on the same space. Her chastised bottom was turning a darker color as Celestia continued to land blows to her bottom. Twilight kicked her legs and Celestia brought two swats against her upper thighs. Twilight yelped as the spanks continued to land. Celestia hoof clapped against the curved, semi-globe of Twilight's derriere.

Celestia stopped suddenly and locked Twilight's legs with her own. Then, she softly stroked Twilight's tushy, pain turning into pleasure. The princess kneaded her rump, eliciting gasps. Five hard spanks fell upon her soundly punished behind as Celestia peppered her posterior with hard smacks.

Twilight's bottom was now lifted up over Celestia's knee, vulnerable to the cascade of stinging spanks Celestia's hoof rained down upon her rump. Twilight twisted and writhed beneath the blows to her bottom. Celestia wrapped a hoof around her waist to keep her in place, then stopped the spanks to rub comforting circles within the punished flesh.

Twilight, when she could think through the haze of ecstasy and agony, noted that each spank landed on the left side of her rump. She wondered why this was until something wooden was pressed against her flank.

Celestia levitated what looked like a wooden spoon except the end was in the shape of her cutie mark, bringing it out of her saddle bag. "Do you want me to use it? A firm reminder of who you belong to."

They had never used anything harder than Celestia's hoof. Twilight knew she could end this with just one word.

She didn't want to.

Twilight panted. Her juices, flowing from her pussy, had completely soaked Celestia's thighs. "Yes. Use it. I'm yours. I want the whole world to know I'm yours. Mark me."

Celestia raised the spoon high into the air and brought it down against the left side of her rump with a resounding slap. Twilight cried out as the spoon fell again and again across her behind. A bright pink mark, in the shape of Celestia's own mark, appeared on Twilight's rump. Celestia slapped the spoon against Twilight's behind right where the mark was becoming imprinted.

The room was filled with the sound of the spoon spanking Twilight's tushy, the smacks falling directly on the reddening insignia. The spoon was much more forceful than Celestia's hoof, the sting staying for longer, building up an intense heat. Each swat of the spoon reddened her bottom and brought a rush of blood to her vulva.

Her entire body was heated with her arousal, the sting of the spanking nearly pushing her over the edge.

Celestia landed a few more swats, lessening in intensity till finally they were more like pats. She rubbed the cool spoon against Twilight's heated up skin and then set it aside, laying her hoof on Twilight's bum and caressing her. Twilight sighed in delight at the feel of her lover's hoof against her behind.

The Sun Princess let Twilight up. "Your punishment isn't over. Go over to the bed and bend over a pillow."

Twilight, curious as to what was coming next, hastened to obey her Mistress's command and climbed onto the bed. She bent over a pillow. She felt tendrils of magic wrap mystical, yellow bonds wrap around her backlegs and then her forelegs. Another strand lifted up her tail, revealing her pretty, pink pussy.

Celestia paused. "Not too tight?"

Twilight looked back. "It's perfect, Mistress."

Celestia plucked one of her own feathers and gazed at Twilight's beautiful, young slit. She hovered the feather over Twilight's hooves, then quickly ran the feather over them. Twilight jerked. Celestia slowly stroked the feather over her hooves, eliciting laughs from the bound unicorn. Then she moved up to Twilight's vulva, tickling her clitoris. Twilight cried out in agonized ecstasy as Celestia sped up the tickling, running it back and forth over her sex.

"Oh, oh!" Twilight squirmed in her bonds, the feather relentlessly running against her pleasure center.

Then the feather was withdrawn. Twilight grinded her hips against the mattress, desperate for release. Celestia took her in her magic, tearing her away from the mattress. Twilight grinded against empty space, her mind drowned with the overwhelming need for release.

Celestia sat on the bed.

"P-please Mistress! I need to come!"

Celestia turned her around so that she was facing her and then she laid back, spreading her legs. "Pleasure me. If you do a good enough job, you will be rewarded with the orgasm of your life."

Twilight plunged her face between Celestia's legs, lapping at her cunt, laying kisses upon her clitoris. Celestia moaned and shivered. "S-slower, Twilight. Slower."

The unicorn obeyed, slowing into an easy rhythm as she lapped at Celestia's clitoris. Celestia moaned back onto the bed as her marefriend's silken tongue pressed against her love button. Jolts of ecstasy crashed through her as she was taken over the edge, her wings and entire body giving one great shudder.

Twilight looked up with her wide, purple eyes, a pleading expression held within them and her face covered in sex juice. "Please Mistress? May I come?"

In response Celestia levitated back over the feather, running long, slow strokes over her former student's delicate flower. Twilight pressed her face into the bed, raising her rump as the each strand of the feather tickled her most intimate places. She cried out, shivering and shaking, her very consciousness being overtaken in waves of heavenly joy. She fell back on the bed, panting.

Celestia spread a wing, wrapped it around the unicorn and pulled her close. Twilight nuzzled against her. "I love you."

The Sun Princess suckled her ear. "I love you too."

Twilight wrapped her forehooves around her neck. "So, you always carry around a spanking spoon?"

"Oh, yes. You wouldn't believe the shenanigans the Guard gets up to. Have to keep'em in line somehow."

Twilight pouted. "I kind of want to be the only pony you spank."

Celestia petted her mane. "It was a joke. I figured you might want to have some fun when I got back though I didn't expect to find you in such
a position."

Twilight's face turned the shade of a cherry. "Should've knocked."

"I quite enjoyed the show." She pecked a kiss on Twilight's nose. Her voice softened. "You must have missed me."

Twilight buried her face in Celestia's chest fur. "You have no idea. But you're here now, that's what matters."

Celestia rubbed her cheek against Twilight's. "So, you going to buy a dress to cover up that mark or...?"

Twilight shook her head. "No. I want everypony to know that I belong to you."

"Aren't you having your weekly lunch with your parents tomorrow?"

Twilight hesitated. "Yeah. A dress. Definitely a dress. Still gonna walk through town, parade it a bit. "

Celestia's face flushed and her wings spread at the image. She brought them back under conscience control and cuddled Twilight in her wings' embrace. "Can you do that after we cuddle?"

"Of course. Or maybe I'll do it in the morning."

There they stayed, wrapped up in one another, both soon falling asleep.
