The door to their cloud home swung open softly and Cloud Chaser trotted through, tiredly. She had spent all day at work dealing with a clumsy gray pegasus who had somehow managed to get her hoof stuck in the cloud-making machinery. Luckily, the mare wasn't hurt, as almost everything in Cloudsdale was made of...Clouds. Unfortunately, Cloud Chaser's entire day involved safely removing the hoof from the machine, fixing the machine, testing the machine, and then countless sheets of paper detailing the incident. Now, she just wanted to crawl into bed and sleep...
"Cloudy, is that you?" a voice called from upstairs.
"Yea, Flitter- it's me." Cloud Chaser replied happily, nearly, if not fully, rejuvenated suddenly.
Trotting up the firm stairs to the hallway that held their bedroom, Cloud Chaser's heart beat loudly in her chest as she neared the door.
Flitter always had a way with telling what type of mood she was in and planned accordingly. Usually, when she had a stressful day at work, this meant she was rewarded in an interesting way...
Call it sibling intuition or something of another name, but Flitter had never been wrong before.
As she approached the cracked cloud door at the end of the hall, Cloud Chaser cautiously nosed it open to peek inside. With a simple, loud, 'poomf', Cloud Chaser's wings spread out from her sides and pushed the door open all the way.
Before her, in the center of their room, stood her younger sister by two months: Flitter, with black latex leggings that stayed on with buckled straps near the thighs before snaking down her legs and connecting to two wooden arches. Around her torso, she wore a large black band that held her wings against her sides so tightly that she couldn't even twitch them.
A pair of large blinders flanked her eyes, while her neck held a collar connected to two leashes- one for pulling, and one that connected to the base of her tail; lifting it up for the world to see her glistening marehood as her big sister walked in.
The two stared at each other in silence for a few moments before Flitter cleared her throat loudly. "Uh...H-How was work?"
Regaining her composure, Cloud Chaser swallowed hard and tried to continue on as if her little sister wasn't bound up like a toy to be played with.
Flitter shifted her eyes nervously around what little of the room she could see as her sister passed her by.
"Uh...It was good. Derpy got stuck, again." Cloud Chaser replied simply.
"Oh. I...I guess you got her out, safe and sound, then?" Flitter asked hopefully as she began to shift her weight, rocking herself forward slightly.
Oh, sweet Celestia, she looks so adorable like this! Cloud Chaser though, suppressing a snicker as her sister rocked back and forth, smoothly, without a sound. And maybe a little sexy...
"Yea, she's free from work for the next week..." Cloud Chaser replied, starting to circle around her little sister and study her curiously. "So, what's all of this about?"
"W-Well, I figured you would be tired and worn out after work today, s-so..." Flitter replied nervously, casting her eyes down in avoidance as her cheeks reddened.
"So you figured you string yourself up as a toy for your big sister to play with?" Cloud Chaser asked quietly as she came face to face with Flitter, who swallowed hard and nodded slightly.
Too adorable... Cloud Chaser thought before pressing her lips to Flitter's, who shivered slightly at the kiss; closing her eyes and moaning softly as her big sister pressed forward, rocking the bound Pegasus backwards a bit.
When Cloud Chaser backed away to let Flitter rock back and forth while she rummaged through some drawers, Flitter panted softly and eyed the string of saliva that hung from her snout.
In a short moment, Cloud Chaser had returned with the pair's double ended dildo and a medium sized vibrator.
"Now, suck on this- be sure to get it nice and slippery -while your big sister sees if you and I can still fit around this lovely stallion." Cloud Chaser said with a giggle as she pressed the vibrator past her little sister's lips and into her snout before trotting around to her flank.
Sucking down on the vibrator was made increasingly difficult for Flitter as she felt her marehood being slowly spread, sending shivers down her spine and making her snout quiver as Cloud Chaser eased the head of the dildo slowly inside her.
When the head was fully wrapped around Flitter's quivering marehood, Cloud Chaser gave it a simple push to send it completely filling her younger sister with more than enough room for herself on the other end.
"Nice!" Cloud Chaser exclaimed as she trotted back towards the front. "I didn't expect you to still fit around it, considering I've never seen you use it for a while."
Flitter offered a slight moan on the vibrator before Cloud Chaser pulled the wet toy from her sister's mouth, eying the saliva-dripping phallus with a wink before placing a bar gag in her mouth. "As much as I love to hear your voice, toys don't talk."
Flitter shifter her weight in embarrassment at the comment, flicking her tail once as she waited for her sister to continue, using her like a little toy and nothing more.
On her flank, Cloud Chaser gently flicked her tongue against her sister's cutie mark while slowly pushing the soaked vibrator all the way into her little sister's tailhole before flicking it on, which made Flitter spasm once in shock before the sound of her panting moans filled Cloud Chaser's ears.
Testing her, Cloud Chaser slapped her younger sister's flank once, firmly, listening to her loud and muffled gasp as she rocked back and forth quickly.
Satisfied with everything, Cloud Chaser smiled triumphantly before positioning herself on the end of the double sided dildo- giving a gasp and a squeak as she suddenly forced herself back against it and making her sister's flank touch her own.
Gripping the leash tightly in her hoof, Cloud Chaser smirked and gave a tug, rocking Flitter forward and away from Cloud Chaser and therefore sliding the dildo out of both of them a bit. When the force of motion kicked back in, Flitter rocked backwards, back onto the toy, and let out a sharp moan as she felt herself being refilled.
Cloud Chaser giggled at her younger sister's expense, tugging on the leash periodically as Flitter's heart pounded in her chest and she drooled on the bar gag.
"Having fun, little toy?" Cloud Chaser asked in between breaths. Flitter replied with a weak moan as she struggled to stay upright, pleasure overtaking her body. Thankfully, two wooden bars connected her front legs and back legs, and wooden splints kept her from buckling her knees.
In short, Flitter was just like a real rocking horse- just a toy to be played with, not even a real pony.
Over time, Flitter's volume increased despite her gag and Cloud Chaser's tugs became harder and more frequent. When a final, hard tug was given on Flitter's leash and collar, sending her forward and then back with such force, the sister's found their marehoods clenching around the slick dildo as it stretched them slightly for a final time- their flanks touching and juices mixing as the sisters moaned passionately.
Cloud Chaser was the first to recover, sliding the abused toy out of the pair and letting it flop to the ground. Right now, her only concern was cleaning her toy for playtime on another day.
Taking the tired Flitter completely by surprise, Cloud Chaser dragged her tongue roughly but slowly up along the outside of her rocking horse's marehood- hanging onto her flanks and causing Flitter to be stuck in a still, backwards rock.
The occasional dart of Cloud Chaser's tongue made Flitter tilt her head back and moan as her older sister teased her abused marehood- going as far as to even fit her entire snout within her and muzzle fuck her gently.
But Flitter had had enough. Her worn marehood had had enough and rewarded Cloud Chaser's efforts with a hot bath of her younger sister's juices- coating her snout and ripping out onto her chest.
With a gasp, Cloud Chaser slid her snout out of her little rocking horse and smacked her flank for a final time, but the little rocking horse didn't respond- opting to simply accept it with a tired yet passionate gasp and rock back and forth while Cloud Chaser licked her lips clean and swallowed.
