The Plan

"Oh my, you're definitely a soggy little filly tonight, aren't you?" Sunburst asked Starlight, who was laying in front of him on the changing table in her room, as he pulled the soaked diaper out from under her. He pulled several wet wipes from the box, and began to gently clean her marehood and around the base of her tail. She only did a little squirming as he finished up and grabbed a fresh foal-styled diaper from the stacks in the shelves that were built into the side of the table. He unfolded it, and slid it under her, quickly and expertly fastening the first set of tapes around her tail, before setting her down on it. He magically grabbed the bottle of foal powder and twisted the cap open, and turned it over and sprinkled it over her diaper area, adding a little extra to the diaper itself before setting the bottle down and brought the front up between her legs and smoothed it against her stomach, bringing the back wings up and began to tape it up.

"There we go, nice and clean." Sunburst said, fastening the last tape on Starlight's fresh diaper, before rolling up the wet diaper and tossing it in the pail next to the changing table. His task complete, he levitated the adult unicorn over to the crib, while also grabbing hold of the footie pajamas that were currently resting on the bed, and quickly got them on her before laying her down, and grabbing the bottle of warm milk from the nightstand, and let her suckle from the nipple as he began to get the bed covers organized. The milk quickly made her eyes grow heavy as it made its way to her stomach. As she made her way through the second half of the bottle, he went over to the nightstand next to her bed-turned crib, and began winding up a music box, that would start playing a lullaby shortly.

"Alright, nighty-night, little Starlight." Sunburst told her, his glowing horn simultaneously tucking the fully-grown unicorn into bed and removing the bottle from her lips. He gave the bed comforter one final test tug to make sure it was snug, before turning and walking towards the exit, joining Trixie at the door, where they shut off the light and stepped out into the hallway, closing the door behind them.

"Well, that was certainly a fun day." Sunburst began to Trixie as they made their way downstairs to the kitchen, Trixie magically holding the empty bowl and spoon that Starlight had been fed with right before bed.

"Indeed. Although, to be honest, I've spent the last part of today thinking about tomorrow." The stage magician replied as they entered the kitchen, taking the bowl, spoon, and bottle to the sink and began running hot water.

"Hearts and Hooves Day? You think that's a good day for more playtime?" Sunburst asked, rinsing out the bottle while Trixie wiped out the bowl and cleaned the spoon.

"Playtime... In a manner of speaking. Have you noticed how Starlight hasn't physically regressed herself with a spell for a few weeks now?" Trixie asked.

"I have noticed, actually." Sunburst replied. It had been over a month since Starlight had used a magic scroll that transformed her into a foal; instead she had opted to stay in her adult form. At first, he thought she had run out of parchment, but that wouldn't have taken weeks to stock back up on.

"Then I'm sure you've noticed how... Aroused she gets when we change her?" Trixie asked, her cheeks tinting considerably, with Sunburst's following in kind.

"Y... Yes." He answered simply. It was the plain truth, which was why he had wondered why it would be taking her so long to get more regression spells ready. It would save her from such embarrassing incidents during changes. Unless...

Unless it was what she wanted. Unless she was clearly enjoying it in that way.

"Sunburst, let me ask you a question, friend to friend. Are you attracted to Starlight?" Trixie asked, her two dishes done and put on the drying rack, and now turned her complete attention to the crystaller.

Sunburst's blushing cheeks only deepened.

"I-Is it that obvious?" He replied nervously, adjusting his glasses.

"No, not that obvious. But I have suspected for a little while. The.. The thing is, I am too." Trixie said, her embarrassment now matching Sunburst's as she began to fidget with her front hooves. "I didn't bring it up, or make a move, because I had my suspicions of how you felt about her, and I didn't want that to come between us as friends. But lately I've been considering... What if we didn't let our feelings for her come between us? What if our feelings were something we could share?" Trixie asked, nearly shivering as her gaze met Sunburst's.

"Does she even, you know, go that way?"

"She's bisexual. She and I had a little wine after one of our performances a few weeks back, and she told me. So, I guess now that the cat's out of the bag, I shouldn't beat around the bush. Is that something you'd be comfortable with?" Trixie asked, fiddling with the corner of her cape.

"W-Well," Sunburst began, trying to keep himself composed as he set the bottle on the drying rack next to the bowl. "Polyamory has been practiced throughout Equestrian history. I suppose it's easier to consider the more comfortable all parties are with each other. When you take that into consideration..." Sunburst paused, thinking to himself for a moment, while Trixie waited semi-anxiously.

"Yeah. The three of us? We're pretty close. I mean, you and I accepted this side of her pretty much without any fuss at all. If we can accept something like that... I mean, why not?"

At last, Trixie gave a hopeful smile.

"So, do you think she'd be alright with it?" She asked.

"Well, based on the past few weeks, seeing how she's gotten during changes... I think playing with her tomorrow is the best chance we'd get at introducing her to the prospect. What do you think?"

The magician gave an enthusiastic nod.

"Let's do it."

Wayward Hooves

Because of the plans they were concocting for the next day, both Sunburst and Trixie spent the night at Twilight's castle. They made it a point to be up early enough to get Starlight up and not have her think that her playtime was over just yet. Although she preferred to spend a few waking minutes in her crib in the morning before magically reverting everything back to normal, her two caretakers entered her room bright and early just as she was waking up.

"Morning, my little Starlight. Hope you don't mind that we've got another day of fun planned for you." Trixie said, magically grabbing hold and levitating her out of the crib and gave her nighttime diaper a gentle press through her pajamas with her hoof.

"My my, you're a wet one this morning." She commented as she took her over to the changing table on the other side of the room, as Sunburst went to the kitchen to prepare her breakfast. As she was floated over to the changing table, Trixie also began to remove her fleece hoofie pajamas, and once those were off, it was clear just how soaked her diaper was, as it was now beginning to sag without the support of the PJs. After she was laid down, the magician began to gather wipes, foal powder, and a fresh diaper. While she did so, she appeared to absentmindedly move the tip of her free hoof up and down Starlight's soggy diaper.

'Might as well start to tease her early, so she's really ready for later.' Trixie thought privately.

After a few seconds of teasing and getting her to squirm, Trixie untaped the diaper and peeled it away from her coat, and immediately went to work with a few wet wipes, making sure to go a bit slower around her marehood, which was already starting to glisten a bit. Halfway through, she lifted the mare's legs and pulled the wet diaper out from under her, tossing it in the pail and unfolding the fresh one and putting it under her before setting her down on it.

All the while, Starlight couldn't say a word due to the small ring around her horn, which she almost always used when she was in this mindset. It reduced any speech to mere babbles, and limited her magical abilities. With enough focused energy, however, she could pop it off, and that was pretty much her version of a safe word, in case anything came up that would have to stop the role playing.

Trixie twisted open the bottle of foal powder and sprinkled it across her entire diaper area, before bringing the front up between her legs, smoothing it against her stomach, and taped it snugly up. Now that her charge was freshly diapered, Trixie momentarily leaned down to the shelves to put away the package of wipes and bottle of powder.

"Alright, who's hungry?" Sunburst asked as he opened the bedroom door, with a bowl of applesauce and bottle of milk, but when he saw the scene before him, he cleared his throat to get Trixie's attention and gave Starlight a rather stern gaze. Trixie came up from the lower shelves just in time to see Starlight's hooves snap back down to her sides after rubbing the front of her diaper.

"Ah ah ah, we can't have you being a naughty girl, especially today." Trixie chastised, lifting Starlight off of the changing table and brought her over to a short stool before sitting down on it, putting the fully grown foal over her lap.

"Sunburst, can you be a dear and grab the hairbrush for me?" Trixie asked, pulling the back of her diaper down, exposing her posterior. She noticed Starlight shudder, and smirked.

'Wow, they aren't messing around this morning.' Starlight thought to herself. Her very first weekend of role play made her realize that she quite enjoyed corporal punishment, and so she was frequently a misbehaving brat, as it made Trixie and Sunburst slowly make their way up from hoof swats, to a ruler, and if she kept it up long enough, the back of a hairbrush. But straight to that? It looked like she would be better off not being disobedient today.

Another moment passed before Trixie magically took the hairbrush from Sunburst's grasp, and lightly tapped it against her flanks, before lifting it up and coming down with a full contact strike.

WHAP!

Starlight gasped as it cracked against her coat. Trixie lifted it up again, and paused, letting her shiver in anticipation for a few seconds. Again it came down, this time on the opposite flank. The blows came gradually faster, each one hard and stinging, until they came nearly once every half second, until ten, when they came to an end, and Trixie pulled up her clean diaper back over her now reddened flanks, and levitated her with her magic again.

"There. Lesson learned, I can only hope." Trixie said, placing her in the high chair next to the dresser, letting Sunburst take over as she set the hairbrush down.

As her thick, clean diaper only minimally dulled the pain of the spanking, Starlight's head was starting to swim a bit, as she wondered what Sunburst and Trixie had in mind for today. They were strict sometimes, but they never went for the hairbrush that quickly before, as they also liked the slow buildup, seeing how frequently she acted up. She could only continue to wonder as a bib, with her cutie mark embroidered on the front, was tied around her neck, and Sunburst came up with a spoonful of applesauce for breakfast.

She was sure there was some kind of surprise in store for today, as another full day of playtime is something they hadn't previously discussed with her.

Just what could they be up to?' She wondered, as her marehood partly wanted her to ignore the sore flanks and try to find another opportunity to enjoy herself.

That would probably be easier said than done, as they were both keeping a rather close eye on her front hooves now...

Polyamorous Playtime

Starlight had just finished dessert, and was now playing on the floor of her bedroom, which was currently covered with multicolored foam titles, surrounded by blocks and plushies. Her last diaper change was in the early afternoon, and she had been quite wet for a couple hours now. But the last time Trixie checked her when Sunburst took the dinner dishes to the kitchen, all she had said was, "Pretty wet, but I don't think you're due for a change just yet."

Starlight figured that Trixie was waiting for her lunch from earlier that way to finally complete it's way through her digestive tract. Sure enough, as if on cue, the pressure in her bowels began to slowly increase and alert her brain of the need to void. No matter how many times they played together, going in front of either of them always made her cheeks burn, especially since they were being so watchful for any more 'naughty behavior'.

She leaned forward like she was trying to reach a just-out-of-reach plushie, and grunted as quietly as she could. From all her hours in diapers, her mind knew that it was a perfectly alright place to go, and thus began to release. She made an effort to keep her pacifier in her mouth as her mess spilled and spread into her waiting padding, hearing muffled squishing sounds from around her tail. She slowly crawled forward towards one of the plush bears, and grabbed hold of it before leaning back into her sitting position, and her had her fresh load spread even further around.

Just then, Sunburst came back in from his brief dish washing trip, and didn't even say anything before sniffing the air.

"Trixie, do you think our little girl needs a change?" He asked her with a wink.

"Yeah, she never stays clean for long..." She replied, getting up and walking over to Starlight, levitating her up with her magic. Starlight felt the back of her diaper stretched back.

"Oh yes, she just filled her pants." Trixie reported, letting the back elastic snap back to her waist.

'Alright, missy. Up on the table." Sunburst said, taking over the levitation and floating her over to the changing table. Laying her down on it, he got out the container of wipes from the shelves underneath the table, and began slowly untaping Starlight's very full diaper, tab by tab, and slowly opened it up.

"Oh my, what a stinky stinky filly we have here." Sunburst stated matter-of-factly, going to work with the cold wipes. He also took note of how well their plan had worked, as Starlight's marehood was quite slick and a bit puffy, and her needy condition was only exacerbated as he slowly cleaned her up, and pulled the dirty diaper out from under her.

To Starlight, this was all very routine by now, but what she didn't expect was for Sunburst to grab a fresh diaper from the shelf, but then levitated her off of the changing table and carried her across to her crib, where he unfolded it, laid it out, and set her down on it, with Trixie coming up next to him as he began removing his teal star-patterned cloak.

"You've been a very good girl today, for the most part, and now we think it's time you got rewarded for your behavior..." Sunburst said, leaning up on the crib mattress, his front hooves on either side of her. Starlight's eyes widened as her mind nearly seized up, as she noticed that Sunburst had, rather quickly, gotten very erect, and was now barely brushing the tip of his stallionhood against her very wet entrance.

"That is... If our good little girl wants her reward..." Trixie said, climbing up into the crib and sat next to her, as Sunburst continued to tease her, waiting for her answer.

Her heart pounded against her chest and her breathing quickened. He actually felt this way about her...! Her adult foal and adult mare headspaces clashed for control as she looked from Sunburst's gaze to Trixie's.

"You don't think we've been teasing you all day for nothing, do you? Well, what's it going to be, sweetheart? Up for a little fun?" Trixie asked, running a hoof through Starlight's mane as she laid there, legs spreading almost of their own volition.

Starlight took one last deep breath, then locking eyes with Sunburst, nodded furiously.

"That's our little Starlight..." Sunburst said, before slowly leaning forward some more and pushing in, gently entering her.

Starlight gasped behind her pacifier as her childhood friend had gotten more intimate with her in the past 15 seconds than she thought possible.

"But don't think it's all him, Starlight..." Trixie said, beginning to climb over her best friend, nearly sitting on her chest, facing Sunburst. "I think our little filly needs her bottle." She finished, magically pulling the pacifier from her lips and lowered her left breast to just above her lips. While Starlight's gaze was initially locked on Trixie's lower lips, now she realized what she had in mind.

"Come on, drink up. Gotta have your milk to get all big and strong." Trixie cooed, lowering herself further as she took in the show that was happening in front of her as Sunburst went slowly and steadily in and out.

Surrendering herself to whatever her friends had planned, she opened her mouth and latched onto her left nipple, and began suckling in earnest, causing Trixie to let out a gasp and a short moan. The moment it hit her tongue she realized it tasted... No different than the bottles she had been given throughout the day.

"What a good girl you are..." Trixie praised, slowly putting a little more weight on Starlight's chin.

Starlight's face burned hot. Trixie must have spilled the beans to Sunburst of what she had said to her that one night over drinks after her show. To be perfectly honest... She couldn't complain, but her mind was still trying to comprehend what was happening, between every squirt of rich breastmilk that hit her tongue and throat, to every gentle thrust of Sunburst's cock, to the thick, soft, clean diaper she was currently laying on. These feelings and headspaces were matters she had managed to keep separate from one another, and now they were all being forcefully crammed together... And it was so fucking hot.

"You get the spell we talked about last night?" Sunburst asked with only a slight shortage of breath. Trixie silently nodded, not wanting to let Starlight in on their plan just yet. But as her left breast ran dry, just as she was about to coax Starlight with the right one, the mare released her hold on it, and instead of going for the right one, raised her head slightly, and wrapped her lips around the magician's marehood, thrusting her tongue forward, getting a satisfying short scream out of Trixie in return.

"Oh!" She exclaimed, lighting up her horn, and managed to cast the contraception spell she had studied last night on Starlight's slick passage that was Sunburst was currently tending to.

"Th-there... She's really getting into it, so... Let her have it!" She said, before letting out another moan and putting a little more weight down on Starlight's face.

With her heightened emotions, Starlight had no trouble lighting up her horn and overriding the inhibitor ring that had been around it for the past two days, and effortlessly cast a synchronization spell on all three of them as the ring popped off and landed on the crib mattress next to her head.

"What... What was that you naughty little filly?" Sunburst asked as he slowly increased his pace.

"You'll see..." Starlight said, pulling away from Trixie's marehood for just long enough to speak before diving in for more.

As Sunburst leaned down slightly to give more force to his thrusts, Trixie also leaned over more, and wrapped her lips and tongue around his horn.

"Ah! Ohh..." Sunburst moaned, glancing up at Trixie, though he could only see her neck. She pulled off after a few moments.

"What? You never said that we only had to play with her..." Trixie smirked, going in for another playful lick to the base of his horn.

"So you didn't..." Sunburst replied, almost panting. It was weird, before Starlight cast that spell, he wasn't sure how long he was going to last. But now, the buildup felt more even, more steady... Not to mention beginning to approach the peak.

"I... I hope you're ready Starlight..." Sunburst managed to say, trying to keep his thrusts even. Starlight didn't respond, or at least didn't respond vocally; just nodded her snout across Trixie's marehood, causing her to grind even deeper.

"Y-Yeah... Same here..." Trixie muttered, starting to go back and forth on Starlight's muzzle.

Sunburst fervently increased his pace, and then hilted and held himself inside Starlight as he erupted into her, just as Trixie very nearly sat on Starlight's head and gave out a cry as her own climax washed over her. Sunburst felt Starlight's own orgasm wash over his stallionhood as well, and through the fog, his mind figured out what the spell Starlight just cast did. A synchronized peak.

When it was over, it took some considerable willpower not to simply collapse on top of Starlight. After all, he had a job to do. After catching his breath, Sunburst lit up his horn, and grabbed the bottle of foal powder from over on the changing table. He slowly pulled out of her before sprinkling her diaper area with powder, then brought up the front and began to tape it up just as their mixed orgasmic fluids began to seep out of her bottom lips, as she licked her top lips after Trixie got up.

"What... What a good girl you were..." Sunburst said, having caught his breath. After the diaper was securely taped up, he crawled up into the crib, and laid down on Starlight's right side, snuggling into her as Trixie did the same on her left side.

"Best... Diaper change... Ever..." Starlight mumbled as she felt herself leak into the waiting padding around her waist. "You know, I was kind of wondering if you guys felt this way about me... I was really afraid that I'd have to pick... But I think you two just solved that dilemma for me."

"Why pick when you can have both?" Trixie said, kissing her on the cheek, before putting her hooves around her. Sunburst did the same with her other cheek.

"Happy Hearts and Hooves Day, little Starlight."
