Recovery and Role Play

As dinner and dessert was wrapped up, Ocellus was mentally preparing for Sandbar's last diaper change of the night, as it was their last chance to have any fun before bedtime. As she set the washed bottle onto the drying rack, the changeling wondered if she had the mental fortitude to go through with what she was considering doing to tap into the deepest, rarest form of love that her kind could taste.

If she got it right, it would probably feel like nothing like she had tasted before. But on the other side of the coin, if she got it wrong, things could possibly take a turn for the awkward. But just as she had been the first to act on her desires when she first trotted into a relationship with Sandbar, it was nothing ventured, nothing gained. After all, as much as she was enjoying the role of big sister, she figured it was about time she tried to at least look the part.

So the dishes done, she took a deep breath, closed her eyes, and carefully focused on what she wanted to change into. A changeling's magic was all about the mental image, so changing into ponies one had seen and were familiar with were easiest to do. But an unfamiliar face and form were trickier, and thus required a bit more focus. Finally settling on what she wanted, she slowly let out her held breath, and there was a momentary flash of light...

After dessert, Sandbar figured he would get in some playtime with his racing carriages and tracks before bedtime. So while Ocellus did the dishes, he quickly got his figure eight track set up in the middle of the room, content to sit in his absolutely swollen and soaked diaper and watch as the plastic carriages zoomed around the track, suckling on his turtle shell pacifier all the while.

He heard hoofsteps behind him over the sound of miniature plastic carriages, but was mostly fixated on whether the red or blue carriage would complete the latest lap first. He felt a pair of legs reach around his backside, and press into his diaper.

"Well, I think my little bro needs a change."

Sandbar's ears twitched at the unfamiliar voice, and he looked down at the hooves currently pressing down onto the front of his wet diaper. Indeed, it wasn't Ocellus' default arctic blue carapace, but something far closer to his own coat. He craned his neck and looked up at the earth mare looking down at him as she withdrew her hooves and stepped back, letting Sandbar swivel on his soaked diaper and get a better look at her new form.

"What, don't tell me you don't recognize your big sister." She asked with a smirk and a wink.

Her voice had a rather cool demeanor. Her coat nearly matched his and Coral's, but wasn't quite either of them. Rather than two tones, her mane was entirely a moderate opal, and came down to just past her neck. She had his dad's eyes, a dark blue. Her left ear had a single silver hoop earring. She didn't look too much older than Sandbar, but her tone definitely gave off an air of seniority, as she looked in her early 20's.

Sandbar knew that Ocellus had very quickly warmed up to her 'big sister' caretaker role, and now it seemed that she had taken bits and pieces of the rest of his family, mixed them up, and had made herself an original, rather attractive sibling form that fit in with the rest of them perfectly.

"Let's get my little brother changed and ready for bed, shall we?" She said, coming forward again, and placed her hooves under his front legs, coaxing him to get up. She led him over to the changing table with a hoof on his back, and gave the seat of his diaper a few light pats as he climbed the stairs and rolled over onto his back.

"Oh my, you are one wet colt tonight, aren't you?" Big-Sis-Ocellus asked, gently rubbing the front of his diaper, getting the expected reaction, as she began to feel a lump begin to form up the center of the swollen and saturated garment. She quickly grabbed a fresh diaper, wipes, and foal powder, setting them next to Sandbar's outstretched back legs, before she began to untape his diaper, and slowly opened it, peeling it away from his semi-erect stallionhood, letting the yellow-tinted padding flop down onto the changing table between his legs.

Saying nothing more, and instead beginning to softly hum to herself, she opened the pack of wipes and began to gently wipe off his diaper area, making sure to clean off his quickly stiffening rod from every angle, while also not forgetting his scrotum, dock, and sphincter, depositing the wipes in a small pile in the used diaper, before pulling it away and rolling it up, refastening the tapes on the bundled up diaper before tossing it into the pail directly next to the stairs. That step complete, she took the clean diaper and unfolded it, briefly lifting up Sandbar's backside to slip it under him and quickly fasten the back set of tapes around his tail, before gently setting him down on the soft padding, as she smirked down at his erection, but made no move for the bottle of foal powder as the telltale green mist began to rise from her nostrils.

"Hm. No matter how thick your diapers get, lil' bro, I guess some parts of your body can't help but get older. I might as well show you how you take care of this, 'cause I know I won't be able to tape this diaper up around that." She said, licking her lips.

Sandbar blushed furiously as he watched Big-Sis-Ocellus descend her head towards his cleaned, throbbing erection, as the lines between lover, babysitter and sibling began to blur in his mind. The tip of her tongue made contact just moments before her lips did, as her mouth began to slowly envelope his tip. He resisted the urge to thrust up, but there was no stopping the filthy, forbidden thoughts that slowly began to creep into his mind.

As Sandbar began to squirm, Ocellus began to feel the familiar tingling sensation that a changeling experienced when they were feeding. But it came faster and... thicker than she had become accustomed to with Sandbar's love of ageplay. She wondered if this was the rare, taboo love that she had heard of, and wondered if it would come out as increased mist, or if it would be different, and depending on how different, would she have the fortitude to deal with it? The last thing she wanted was another love-filled magical explosion, much less in the middle of Sandbar's neighborhood.

Her tongue swirling around as she continued to descend, she felt him twitch as the tip of his cock began to flare, bumping against the roof of her mouth. His last climax was this morning just before breakfast, so it was safe to say he was sufficiently pent up and ready to expel the load that his body had been building up all day. She heard him whine lightly, and that just made the thick, viscous love continue to collect in her chest and stomach. She exhaled through her nostrils, and though the mist increased, the collection in her gut didn't subside in the slightest.

Moaning, Sandbar continued to writhe lightly on his clean diaper as his imagination began to run wild with this scenario, with his cool, somewhat aloof older sister showed him how to deal with the urges that came with being an older colt, no matter how long he had been in diapers. Their parents had saddled her with babysitting duty for years, but he never thought that things would get this far. To be fair, he also thought that he would be out of diapers by this point.

"Mmmm... Ahhh... Ah, ah, big sis, I'm... I'm... Ah!!!" That was all Sandbar managed to get out before he instinctually bucked his hips up, and felt his cock launch its first burst, splattering the roof of his sister's mouth.

Instead of acting surprised, Big-Sis-Ocellus only took it in deeper, resisting her gag reflex, and the second squirt of seed went directly down her throat. She was able to open her glowing green eyes to look at her lover in his as he continued depositing his load. With every spurt, that warm tingly feeling in her gut only grew, and she had a feeling it wasn't the seed that Sandbar was giving her, but the lewd fantasy currently being played out between them that had tapped that taboo, forbidden love.

The spurts of warm cum began to die down, and she felt his cock begin to soften as she pulled it away from the back of her throat, and as it left her lips and flopped down on his stomach, she felt her sense of balance begin to waver. Thinking quickly, she grabbed the bottle of foal powder, quickly gave his diaper area a quick dusting, and tightly taped the clean diaper around his waist and stomach. Sandbar lifted his head just in time to see Ocellus, still transformed, teetering with the goofiest open-mouth smile, begin to tilt to the left and fall to the bedroom carpet in a heap.

Fighting through the post-orgasmic lull, Sandbar sat himself up on the changing table, and gazed down at his transformed feedmate, mane splayed over her face and across her neck and the carpet, as she softly giggled to herself.

"Ocellus? You alright?" He asked, beginning to get a little concerned.

"Heh... Hehehe... So this is what it feels like..." She said to herself, hiccuping, a green misty bubble popping out of her mouth, rising to the ceiling before popping.

Sandbar carefully hopped off of the changing table, and back legs still a bit wobbly, he unsteadily made his way over to the open bedroom door, peering out into the hallway to make sure all the lights were off, then turned back into his room and walked back over to the giggling Big-Sis-Ocellus. He bent down and helped her get to her feet. He had never seen a changeling drunk on love before, but he was guessing that this was precisely what she was going for during that diaper change.

"Love you, little bro..." She managed to say as he helped her over to the crib, rolling her over to the far side. He quickly went to switch off the light, and the night light plugged into the wall next to the crib switched itself on automatically from the darkness as he climbed in after her and raised the bars, laying down next to her and wrapped his front legs around her, the front of his diaper pressing against her lower back.

"Love you too, big sis. Love you too."
