“Oh Shy… You look so cute like that.” Rainbow snickered. Watching lustfully as the yellow pegasus squirmed under the leathery ropes tying her down.

Fluttershy whimpered, coating in saliva the red ball-gag stuck in her mouth. The ropes spreading her hind-legs apart over the bed.

Rainbow Dash nuzzled her flank softly, the touch of her friend’s wet fur sending shivers down her spine. Rainbow was kind enough the let the pegasus's wings untied, so they could stiffen and throb.

Fluttershy blushed so hard she could barely keep the reddish warmth inside her cheeks and face.

“I know you don’t like surprises.” Rainbow admitted, pacing around the bed and pulling her dark corset tighter. “But I’m sure you’ll love this one.”

Letting out a chuckle, she whipped Fluttershy’s flank with a thick leather whip.

Fluttershy let out a muffled cry.

“Come on, I’m just playing with you.” Rainbow rolled her eyes. “It’s not like I’m forcing you to do anything… Even tho I’d love to.” She gave a mischievous smile, thinking about the possibilities.

Fluttershy was barely laying on her stomach over her bed, legs spread apart and tied to the bedposts, her glistening marehood roughly exposed. Around her chest, a lavish corset laboriously tailored by Rarity, for purposes unknown to her.

The clothing was very tight, and made it slightly difficult to breath. But that was a special request made by Fluttershy herself, alongside with her tinted leather socks.

“Don’t you feel sorry for the little animals, Fluttershy?” Rainbow teased her, already up in the bed. “All this ‘dead skin’ wrapping your body.”
Fluttershy muttered something Rainbow couldn’t make out. Probably another lazy excuse.

“Well, they look sexy anyway.” She said, biting her leather-covered leg, just enough to leave a mark.

The yellow pegasus moaned, squirming under the ropes. She turned her head to look at Rainbow, who mindlessly played with the contours of her body, running her silky hooves along the length of her spine.

Fluttershy shivered, struggling with the realization of such a nasty thing she was doing.

Stopping her games for a while, Rainbow crawled to the other side of the bed, laying down face to face with Fluttershy. The pegasus’s pinkish mane was done in a cute ponytail, her shy bluish-emerald eyes displayed a sheer curiosity.

With a heart-shaped key, Rainbow unlocked the head harness locking the ball-gag in place. A string of saliva escaping from her mouth as the red ball was taken away.

Fluttershy let out a deep breath, her cheeks in two tones of crimson.

“A-are you s-sure this is a good idea?” She muttered.

“It is the most fantastic idea.” Rainbow stated, biting down her lips.

The adventurous pegasus wasn’t nearly as constrained as Fluttershy. Rainbow wore nothing but a pair of stripped socks, and a black collar with her name written in silver letters. But Rainbow was prepared, and she bought with her a small suitcase with all sorts of entertaining apparatuses.

Rainbow tilted her head to the side, planting a kiss on Fluttershy’s lips. Although her automatic response was to back away, Rainbow held her close by the chain leash that surrounded her collar.

“You’re not going anywhere…” Rainbow chuckled, biting the shy pegasus lower lip.

Fluttershy had no time to complain, as the prismatic mare had already found a way through her clenched teeth, pressing her tongue against the tip of her own.

Deeply, a pleasurable wave crashed on the insides of her body. Although she would never openly admit, Fluttershy liked to be dominated, to be forced, ordered – only by certain ponies, of course.

That was a matter of trust, not only lust.

Drawing circles with their tongues, sharing their tastes, Fluttershy let Rainbow explore the depths of her mouth. It was an arousing intrusion she wouldn’t deny.

As they breathed, puffs of foggy steam floated away, and she could feel the cold touch of the air in her heated tongue. “I’ll be back in a second” Rainbow whispered. “Don’t you dare to move” She sarcastically said.

Having no other choice, Fluttershy remained in place, her body was hogtied in a way that she was unable to see what was happening behind her back, as she could only face the wooden headboard of the bed.

A million thoughts crossed her mind, but the most important of them would only be spoken at the right moment in time.

For now, she was nothing but a submissive pet.

“Do you like toys, don’t you?” Rainbow asked, her husky voice displaying a sarcastic tone.

“Y-yes…”

“Yes what?” Rainbow growled. Whipping the pegasus’s flank again and eliciting a cry that pleased her ears.

“Yes mistress. I love toys.” Fluttershy replied between sobs.

“Good, because I’m about to have some fun.”

A whirring sound grew in intensity, and the lustful warmth of Rainbow’s body could be felt in the air, as she approached Fluttershy from behind. Something unknown to the pegasus tightly held in her hoof.

“I bet you’ll enjoy it.”

A sudden jolt of electric pleasure crawled through Flutterhsy’s body, her flanks tried to move up, but her erratic movements were restricted by the series of ropes and leather bonds holding her limbs in place.

“What’s the matter Shy? Can’t defend yourself?” Rainbow teased, rubbing the bulbous silicon vibrator back and forth against her pussy.

“Hnnngh… R-rainbow please.” She moaned, biting the pillows in front of her.

Rainbow Dash basked in the sight, feeling her own cunt starting to leak a drip. She touched her moistened slit, chewing the insides of her mouth as a shiver ran down her spine.

Without warning, Rainbow inserted the tip of the toy into Fluttershy’s pleading cunt, her tight pussy winked and squirted out some clear fluids.
“Wow, you’re an eager one.” Rainbow said, planting one of her fore-hooves on the bed, while her chest rested on top of Fluttershy.

“W-what are you going to do with me, mistress?” Fluttershy muttered.

Rainbow pulled her collar, forcing the pegasus to look at her. Fluttershy trembled, her body urged to move, but she found herself practically glued to the corners of the bed.

“I’m going to spread you open…” Rainbow whispered, nibbling the tip of her ear. “And then I’ll drench this bed with your own cum. You’ll try to flee, but your wings will be useless. I’ll make you beg for more, as I play with you.”

Fluttershy wriggled under pressure, her heart on fire as Rainbow bit her ear removing the dildo from her slit, only to start stuffing her clenching pussy with a thick horsecock. Fluttershy moaned shakily, feeling the slippery object prodding her deepest barriers.

Rainbow wasn’t kidding.

Two clanking sounds announced that the fastest flier had bought the best of her collection to their game.

Pulling out the purple cock from Fluttershy’s cunt; Rainbow attached it to a leather strap-on she wore around her waist, like an officer holster belt. She had this kinky obsession for authorities, and never missed a chance to be one. Or at least pretend.

Unlocking the two cuffs that secured Fluttershy’s hind-legs, Rainbow positioned herself behind her.

“Raise that lazy flank of yours” She growled, cracking the whip in the air.

Now with her fake cock between her legs, Rainbow mounted the yellow pegasus, grabbing the spaces between her wings and the tight corset.

Fluttershy gasped, breathing loudly.

“Good girl…” She snickered.

With a sudden thrust, Rainbow buried half of her length inside Fluttershy’s dripping honey pot.

“Hnnnnnnnnnnnnh…” She let out a muffled moan, burying her face in the bed sheets.

“Ah, come one, I want to hear you!” The whip cracked again, this time against her cutie mark.

“AHHHHHHHHHHH- R-RAINBOW!” She yelled, a tear running down her cheek. Fluttershy panted, her insides being spread apart by the rough pushing and pulling.

It hurt, but it was a delicious kind of pain, to be rutted down by her mistress. She wish she could please her mistress, but a rubber cock could give Rainbow no true pleasure, she thought.

Fluttershy bent down feeling her sticky fluids pouring down on the bed, and drenching their fur. Her tail was damp and hung to a side, its base surrounded and tied by strips of red cloth.

“Yeah, bend down for me!” Rainbow hissed. Sweat dripping down her forehead, and glinting on Fluttershy polished leather stockings.

Fluttershy nearly lost balance of her hind-legs as a strong orgasm crashed inside of her like a wave on the shore. A throaty moan escaped her lungs as a stream of fluids cascaded down from her quivering insides, coating her legs with a sticky moisture.

Rainbow heaved as she finally pulled out from Fluttershy. Unbuttoning the belts and scuffs, so they could lay down on the bed.

She sighed in pleasure, staring at the ceiling.

“Well, t-that was good. Being fucked by somepony as amazing as me must be gorgeous” She muttered, smiling at the thought. “You liked it, Shy?”

The room was silent.

Rainbow turned her head around, looking for her mate, but the Pegasus was nowhere to be seen. “Fluttershy?” She called, cocking an eyebrow. “Where are y-”

CLANK!

Rainbow couldn’t speak. She was blind, she was… Chained?

Fluttershy smiled malevolently, as she dragged the blindfolded pegasus through her room, a steel leash wrapped around a large collar.

Rainbow murmurs were practically inaudible from under the mask.

She dragged her down the stairs, leading to small basement under the cottage. A place she so tenderly prepared for Rainbow.

Fluttershy smiled, thinking of all the fun they would have together. She already had her share of being the submissive puppet, now it was time to change the course of things.

The pegasus did not hesitated, when everything was ready, she removed the dark blindfold from her rainbow-haired friend. The air smelled of rubber and… lube. And a multitude of objects were displayed on the walls.

Some clearly recognizable ones, and some she had never even dreamed about.

In a glass cabinet, a flask of violet liquid sparkled in the dark. In another one, a fancy pair of expensive-looking outfits awaited in a hanger. A long and sparkling dress, a white beauty someone would very likely find in Carrousel Boutique, and a tactical vest stamped with Fluttershy’s cutie marks on each side.

“No…” Rainbow muttered.

Fluttershy laughed, sounding almost like a different pony. Her dark side taking over her docile mind.

“Prepare your pussy, my little cock sleeve!”

“Fluttershy… Please, no!” Rainbow whined, contorting inside the dress.

Fluttershy ignored her pleads, inspecting the sparkling potion, as she grabbed her military-looking outfit. A gift, from a distant ‘friend’. Unlike most of her friends believed, Fluttershy was a chest of secrets, and only a few of them she was willing to reveal.

Rainbow Dash stood in a corner, lying against a red satin armchair. That girly dress made her incredibly cute, but awfully uncomfortable. After two or three shouts, she was compelled to wear the socks as well.

“Where did you found all of these things!?” Rainbow asked, inspecting herself and trying to hide a blush.

“Well… I have my ways.” She replied with a sweet voice, even though she looked anything but sweet. Fluttershy looked like a high-ranking official in formal dress.

Rainbow thought it was oddly sexy, but kept her mouth shut.

In a single gulp, Fluttershy swallowed the potion, giving a sigh of relief and a soft chuckle. After a few seconds, the pegasus turned around grinning.

“Well, now we won’t have to worry about the strap-on” She said, raising a hind leg and revealing a fully functional penis. Rainbow Dash gasped, her jaw almost hitting the floor.

“You d-didn’t… No…” She muttered.

“No more talking” Fluttershy shushed her. “Now lay down, miss, for I have to inspect you.”

Although her speech sounded clumsy coming out of a pony like Fluttershy, her outfit gave her an air of authority, and Rainbow wouldn’t dare do disobey.

Dash turned to lay on her back, spreading herself open on the large satin armchair.

Planting her hooves on each side of her body, Fluttershy planted a kiss on Dashie’s neck, trailing down her tongue, feeling the surface of her fur. The hair on the back of Rainbow’s neck stood up, entranced by the new sensation.

Rainbow pulled her closer, theirs chests brushing together while Fluttershy's hind legs balanced on the floor.

Dash’s legs caressed Shy’s erection, her socks giving it a nice and silky touch.

Fluttershy gasped, pushing her hard cock against Rainbow thighs. The chair was at the perfect height to do whatever she wanted. Rainbow gave a girlish moan, biting her lower lip as she felt that heavy junk pressing her lower belly.

“F-fuck. Why did you never told me about this?” She asked, lifting her fluffy dress.

“I thought you liked surprises?” Shy replied, using a hoof to rub her garish dick against Dashie’s clit, a wet droplet already oozing from the tip.

“Unf” Rainbow closed her eyes, as her friend did nothing but tease her sensitive flesh, rubbing and prodding, sliding her shaft between her pink lips.

Satisfied with her ‘torture’, Agent Fluttershy finally pushed her dick against the barriers of Rainbow’s pussy, eliciting a strong contraction that coaxed her dick to go further.

Dashie’s hind leg kicked in the air as Fluttershy thrust deeply, stuffing her warm insides with pure cock.

Shy’s mind boiled with lust, never in her life she imagined that fucking a mare could be so good. Precum leaked from Dash’s pussy, serving as natural lube for each thrust she gave.

Rainbow’s wings were stiff as rock, and could barely fit on the armchair, feathers sticking out at random.

“F-fuck, that’s the best thing you ever-” Rainbow muttered, her back arching as Fluttershy increased the pace, pulling her cock out only to thrust again even harder, Dash’s pussy eagerly engulfing all of its length.

The flaring tip brushed against her deepest barriers, making her shiver and tremble. Her hooves felt limp as shivers ran down her spine.
“Ahh- Yah F-flutter, I’m… I’m g-going to-” Dash stuttered, digging her front hooves on Flutter’s back, spreading her legs further, the rough surface of Shy’s outfit rubbed against her chest and made Dashie even hornier.

Fluttershy pulled her closer as she came, her throbbing magical member releasing spurts of melting pleasure, filling Dashie’s insides with everything she deserved.

“Oh d-dear!” She panted, surprised at the amount of gooey stuff that came out. Dash couldn’t utter a word as she climaxed harder than ever before, an overwhelming feeling of tingles throughout her body, all her muscles tightened up as if pulling herself from the insides.

Both of them panted, staring at each other, and analyzing the scene with incredulous eyes.

Fluttershy was the first to part, leaving a trail of white cream on the floor of her ‘dungeon’, and collapsing on her back at the nearest bed.

“Wow…” Rainbow said, static in her place. “T-that was awesome!” She heaved.

“Yay” Fluttershy squealed. “Just wait until I bring the bears!”
