“Come here, pet.”

Stonecutter stood in Fluttershy’s living room and she looked at the yellow collar and immediately, she got the idea as to what was in the very, very pink bag. As such, she hesitated for a split second. She had wanted that, yes, when she was talking with Sparkler in the Everfree Forest, but now she was confronted by the reality, she hesitated. Cloudburst saw that and rested her hand on her best friend’s shoulder. “Stone, it's cool. She loves you, even I can see that.”

When Cloudburst nodded her head, Stonecutter smiled and nodded. Making her mind up, she walked over to Sparkler and she bowed, exposing her neck. Fully realising the weight of what she was doing, the bright yellow unicorn fastened the collar around her marefriend's neck. “That looks so good on you,” she kissed her lips and then stood back to admire the new accessory standing out against her slate grey fur. “We can work up to you wearing that in public, but for now it is really nice.”

“Nonono...I'm good with wearing it.” Stonecutter put in quickly. Cloudburst had told her many times how it felt to wear Seafoam’s collar. She hadn’t understood it, back then. But, now that she was wearing Sparkler’s collar, knowing what it meant to them both, that she was loved so very much, it made sense.

Cloudburst looked from Seafoam to Sparkler to Stonecutter and she shared a knowing smile with her Master. One only had to look at the two mares and you could feel the love and trust between them. “It’s the most natural thing ever.”

Next, when she delved into the bag of goodies, Sparkler pulled out the leather handcuffs. “And these?” she asked, inspecting the padded interior and the buckles that would keep them secured on her pet. She was glad they weren’t ones that locked. It meant she didn’t have to worry about where the key was.

Almost immediately, Stonecutter nodded. “I'd wear those in public, Mistress.” The cuffs were like the ones Seafoam used on Cloudburst, with an adjustable chain so they could go from twelve inches apart all the way down to locking them both together by the D rings.

Sparkler whispered into Stonecutter's ear, “And nothing else?”

Stonecutter erupted in such a blush that the overweight earth pony mare practically burst into flames. She couldn’t quite find her voice but nodded her head slowly. If her Mistress wanted her in public like that, that’s what she would do. “That's the spirit!” Cloudburst exclaimed, high-fiving Seafoam.

“That's good to know.” Sparkler gave Stonecutter a tight hug, though she could barely get her arms around her generous girth. “So, Foamy,” she said, trying very hard to keep herself from letting out the biggest squee she had ever made – appearances had to be maintained, she knew that, “the leash I understand,” she pulled that out and set it on the coffee table, “But this last item...”

Cloudburst knew, from her peek in the bag that the only thing left in there was the flogger. “You'll love the last item!”

“What?” Stonecutter asked. She wasn’t paying attention, for she was still looking at the cuffs and imagining herself being led down the halls of the Friendship school or out into the marketplace wearing those, her collar and nothing else. She now had a new fantasy to rub herself off too.

Despite being the ‘dominant’, Sparkler was too embarrassed to pull the yellow flogger out of the bag so, for a distraction, she instead placed the cuffs on Stonecutter’s wrists and motioned for her to put a hoof on the chair between her legs, so she could put the cuffs on her ankles just above her hooves. Obediently, the earth pony placed her hoof up on the chair, while Cloudburst was on her knees by Seafoam's hooves, her default position. “I would think the application of that last item is obvious,” Seafoam said dryly, “Still I could give you a demo if you like.”

“Oooh!” Cloudburst thrust her hand up into the air far more eagerly than she ever had done in class, “ooh, I volunteer to demo, Master!” Seafoam just petted her head and he used a minor eye roll to shush her. Secretly though, he was grateful for her enthusiasm, because it distracted him from what had occurred the night before.

“I wouldn't mind having a demo,” Stonecutter smiled at Sparkler. Ever the pragmatist, the earth pony reasoned that if they were going to do this, they may as well do it while they had the far more experienced couple close at hand to offer guidance and make sure they were doing it safely. She pointed to the bag, “I'm guessing from past form you got a crop or something, CB?”

Slowly, with a trembling hand, Sparkler pulled out the flat, flexible, yellow paddle, holding it as reverently as if it was the trophy she won in Canterlot high school for getting the highest grades across all her years. “Flogger is the right term,” Seafoam supplied, “It’s a beginner item.”

“Oh my...” Stonecutter pictured that impacting against her fat ass and she pressed her thighs together for she got very wet indeed.

“In our dorm room we have a crop, flogger and a cane. I love the cane, but that should do you guys for now.” Cloudburst explained, getting very much into the lesson that she and her partner were giving. For once, she wasn’t thinking about the life that was inside her.

Seafoam shrugged, “I only brought our flogger anyways.” He chuckled, because he knew that his pet didn’t know he bought a full set of ropes along too. He was just saving them surprise for her. He knew he spoiled her, but to him, Cloudburst was worth spoiling.

“That's okay, Foam, I'm happy starting small,” Cloudburst sniggered when her best friend said that, because nothing about the earth pony was small. Stonecutter glared at the kneeling pegasus. “Bite me, featherbrain.”

“Then there is the art of the naughty, which you'll need to learn, Stone.” Seafoam gently but firmly tapped his fingers on his pet’s muzzle, making her scrunch up her eyes. “I doubt Miss Cloud-for-Brains will be the best teacher.”

“Hey!” Cloudburst protested, “I resemble that. I can be good bad.”

Smiling, because he knew full well that she could, Seafoam walked over to one of the ottomans around the coffee table and he pointed at the floor beside it. “Stand here, pet.” It wasn’t a request. If they were going to put on a demonstration, he was determined it was going to be a good one.

“Yes Master.” The change in Seafoam’s voice from easy going to commanding marked a similar change in the pale blue pegasus. Her voice was the same, but there was a definite submissive aspect now that wasn’t present a few moments ago. While she obeyed him, he went and got his own backpack from beside the other couch.

Reaching into his bag, Seafoam took out a set of four turquoise cuffs. “Get down on the ottoman.” He ordered, taking note of the fact that as his pet was doing as she was told, Stonecutter and Sparkler were both watching with as much attention that they may have been in class. Seafoam took a moment to admire Cloudburst in her shorts and tee bent over the ottoman before he took their leash from his bag. “The nice thing about the leash is you can do this. Attach it to one ring on the cuff and run it through the other rings. A simple half hitch will keep your subject in place.”

Sparkler watched intently as the hippogriff twice demonstrated what he had just said. “I never thought of using the leash like that.”

As Seafoam demonstrated the use of the leash to tie her down, Cloudburst had a very happy look on her face indeed. “I've seen you do that before,” Stonecutter said, “when you let me sit in on one of your sessions in your dorm room.”

“Then this next part shouldn't surprise you,” Seafoam stated as he undid Cloudburst’s tail fastener and lowered her shorts – as was the norm, she was wearing no panties – midway down her thighs to expose her bare ass. Lightly, he rubbed his clawed hand on said ass, loving the way his pet’s tail raised up of its own accord and the way Sparkler looked away only to look back.

“Mmmmmm…” Cloudburst parted her legs, or rather she tried to part her legs. It was kind of hard to part her legs as she was leashed to the ottoman, but it was more of an automatic reaction.

Stonecutter held Sparkler’s hand, squeezing it reassuringly. She’d had the same reaction months ago when she first saw Seafoam dominate her best friend. “Yeah, I've seen this before…”

“The flogger is a nice instrument.” Seafoam continued like he hadn’t paused. “Flexible and solid. Makes a lot of noise and has a bit of a sting. About as much as a hand, but easier on the hands.” He snickered, “The crop has a smaller surface and a lot more speed. The cane isn't as flexible and that means more force. Definitely not for beginners.” He placed a lot of emphasis on the word ‘not’ as he rubbed the flogger over Cloudburst’s ass.

Without realising it, Sparkler squeezed the hand in hers, and she found herself mesmerized by the demo happening in front of her. Getting very much into it, she watched Cloudburst lift her tail ever higher to present herself to Seafoam, his claw and the flogger. Stonecutter did not let go of her marefriend’s hand. “This is hot, Mistress.”

Sparkler just nodded. She watched the hippogriff raise the flogger. She watched it swing. Still, she flinched when it landed on target with a loud slapping sound that made the small pegasus lurch forwards on the ottoman. They all ignored the ‘aaaaah!’ she made. “Easy to use at any skill level. Most likely your strike will be light instead of hard, but you can still get a good sting with this.” Seafoam whapped his pet again, giving her a few more solid hits on different locations on her ass.

“Aaaah! AAaaaaAAAAH!” Cloudburst moaned and screamed softly with each strike, making sure to keep her tail up high. Watching the show, Stonecutter simply squeezed Sparkler's hand a little harder, because she was imagining herself in Cloudburst's place.

“Of course, a demonstration can only cover so much ass,” Seafoam snickered, “I think it’s time for the lab portion of this discussion.” Getting what he meant, Sparkler placed her free hand up to her mouth and her green eyes went wide as saucers. “I think Stony would go well on the coffee table. I'll just add this quilt to the top for a bit of padding.”

As Seafoam did indeed add the quilted blanket from the couch to the coffee table, Sparkler turned to her marefriend, concern mixing with arousal on her face. “You want to do this?” she asked.

Stonecutter appreciated the opportunity given by her marefriend and Mistress to back out of what was about to happen, but if she was honest, there was no way she was going to stop then. She had known, deep down, when the collar was affixed around her neck, she’d see this through. “I really, really want to do this, Mistress.”

Steeling herself, Sparkler took several deep breaths to get herself centred and calm, and, once she was ready, she pulled Stonecutter with her to the coffee table. “No time like the present.”

Stonecutter bit her lip as she watched Cloudburst watch her bend over the coffee table. “I’m really doing this...I'm really doing this!’ she thought over and over in her head. She adjusted herself on the table, getting comfortable on the quilted blanket. Before she knew it, Sparkler had attached the yellow leash to a front cuff and had woven it through the others before tying it off just like Seafoam had just shown her.

Watching her work, Seafoam was impressed with Sparkler’s deft movements. It was as if she had done this many times before, rather than it being her first time ever. Clearly, she was a quick study. He liked that. It meant he didn’t have to repeat himself. “A scout couldn't have done that better,” he teased.

“Hush you…” even though she blushed, it was clear Sparkler thrived on the praise.

“Told you she was cool!” Cloudburst winked at Sparkler, whose cheeks just grew redder.

‘Oh...oh my...’ Stonecutter thought. Testing the binding, she knew that as strong as she was, she could easily break free, but, strangely she was not as strong as she usually was in this situation. Then again, she’d never been tied up by her marefriend before, so this was something new.

Sparkler hooked her hands around the tail fastener of Stonecutter’s cargo shorts, resisting – just – the temptation to grope that huge ass. “May I?”

Stonecutter hurriedly nodded her head so hard she almost gave herself whiplash. “Yes Mistress!” Permission given, Sparkler unfastened the earth pony’s shorts and pulled them halfway down her thick thighs, mimicking Cloudburst. This manoeuvre, incidentally, gave Stonecutter a clear look up the unicorn’s knee length plaid skirt. “Nice view,” she giggled, in an attempt to calm her sudden nerves.

Now that Stonecutter’s shorts and panties had been pulled down, Sparkler couldn’t keep her hands off her bare ass. Seafoam snickered, “Spanking can be done with the hands, but you should use the flogger first.”

Cloudburst winked at her best friend, bound in the same way she was. “Excited, mud pony?”

“Oh hush...” Stonecutter gasped. As it happened, she was very excited. Every time she felt Sparkler’s delicate fingers caress her wide ass, she wagged her tail invitingly, as if such an invitation was necessary.

“You do have a fine ass, Stony,” Seafoam said appreciatively as Sparkler retrieved the yellow flogger she left in the MiAC bag. “Too bad you can’t see it, pet.”

The pale blue pegasus snickered, “I've seen her chubby ass in the school changing room plenty of times.”

Sparkler snorted as Stonecutter blushed. She knew full well how she felt about her body. “Stop staring at my marefriend's ass,” she snapped in as dominant a tone as she could muster, “That beautiful ass is all mine.”

That tone impressed Seafoam and shut Cloudburst up all at once. “Yes ma'am!” the bound pegasus squeaked, her wings fluttering to half-mast.

‘She really thinks I'm beautiful!’ was the thought that ran through Stonecutter’s head, her tail lifting and wagging all on its own. This was quickly becoming one of the best days ever. Definitely top three.

Smirking, Sparkler continued, “I do think she’s a bit pale though, don't you agree, Foamy?”

“For sure,” the hippogriff agreed, tapping his flogger to the unicorn’s in a salute, “a bit of red would really help her colour.” No sooner had he said that than the yellow flogger landed on Stonecutter's wide butt with no warning at all.

“AAaaaaah!” the earth pony mare screamed. Her eyes were wide, for the blow had caught her completely by surprise. She squealed with the force of the impact. It didn't hurt her as such, but it stung her in a very good way that made her damp marehood positively wet through with arousal.

“Good, huh?”

Stonecutter nodded at her fellow submissive. “Very good!” Behind her, out of her line of sight, Sparkler smiled and landed four more quick smacks on her pet’s ass, twice on each cheek. The way it rippled under the flogger was hypnotic. “Ooooooh! AAAaaaAAAH!” she yelped, even her fat ass was turning a dull red, wobbling like a jelly with each well placed strike.

Unable to resist any longer, Sparkler placed a hand on one of those ass cheeks and wobbled it even more. “You are so sexy!” she breathed, for she could have eaten from those luscious mounds they were so beautiful.

Not to be outdone, Seafoam moved back over to Cloudburst, ready to move onto the next part of the demonstration. “When you use your hand, be sure to extend the fingers and keep them together. Cup the hand slightly, like so…” he showed Sparkler what he meant and then he promptly delivered two hard smacks to Cloudburst's butt.

“Oooooow ooooh yeeeah!” Cloudburst moaned very happily as she was spanked, the submissive pegasus dripping wet already just from the first spank.

Lifting her hands from Stonecutter’s huge ass, Sparkler adjusted her fingers so they were positioned like she had just been shown and she brought both back down quickly, impacting her pet’s behind with a resounding slapping sound that practically echoed around the living room. “Gaaah! AaaAAAH BUUUUUCK!” the earth pony screamed, now very wet indeed, her tail was up and out of the way, presenting herself like a mare to be rutted.

Seafoam was very impressed by his ‘student’s’ prowess. Not only did she learn fast, she wasn’t afraid to put what she had learnt into practise. He particularly liked how she wasn’t holding back with little tentative love taps. She presented the look of a dominant who trusted their sub to tell them if it was too much. That alone had him hard in his pants. “I'll match you stroke for stroke, Sparks.”

“You’re on!” Sparkler answered straightaway. While she wasn’t holding back with her spanks, she was slow though, because with each strike she delivered, she loved to clutch Stonecutter's giggling butt cheek and caress it, admiring her handiwork. Seafoam was true to his word and, for the next twenty minutes, the cottage echoed to the sound of tandem smacks and screams. While the earth pony wasn't feeling the pain as much as Cloudburst was, she was big and bulky after all, after twelve strokes she was letting out almost identical whimpers and moans to the pegasus, both mares sporting bright red asses.

Sparkler didn’t really hear the slaps or the screams. She was focused on the jiggle and the slowly grown red glow of Stonecutter's butt. After the fourteenth smack though, she stopped to blow on her hands. They were getting red too. “That’s why there’s a flogger,” Seafoam chuckled, delivering a spank to Cloudburst’s ass that bought tears to her eyes. “A bit less personal, perhaps, but it will last longer.”

“Thank you for the flogger,” Sparkler nodded to the more experienced dominant, “but I love the feel of her ass in my hands too much.”

“I love the feel of her hand on my ass!” Stonecutter exclaimed, both she and Cloudburst were getting rather red and soaking wet by now, the pegasus had her wings out, hard as a board.

Seafoam returned the nod. “Has Stoney told you her safe word?”

“What?” Something she didn’t understand stopped her dead like cold water poured all over her.

Shaking his head, the hippogriff explained, “The submissives are always the ones in charge. The safe word lets the dominant know it’s time to stop the scene.”

Realisation dawned on Sparkler’s face. “Oooh.” She then squeezed those reddened ass cheeks, “So what is it, pet?”

“Oh um...” caught a little off guard, Stonecutter didn’t really know. She knew Cloudburst’s safe word was ‘harmonica’, because that made her think of her parents, and nopony wanted to think of that while in the act of being bucked senseless. “I'll chose...lettuce.”

“Lettuce?” asked Sparkler, Seafoam and Cloudburst all at once.

“Tasteless horrible stuff…”

Sparkler couldn’t help but giggle. “You're lucky I'm not going to make you eat it.” Although, she stored that away in her brain for a later punishment. “So, when is the word used?” she asked, wanting to be absolutely clear on this most crucial detail.

“I bet she'd say it the moment you whipped some out,” Cloudburst giggled, still leashed over the ottoman, “It's used by the submissive to end the scene when he or she isn't happy with something, is really hurt or thinks he or she is in danger. The safe word is also used by the dominant if they need to stop the play, if they are uncomfortable with something.”

Stonecutter was amazed. “How come you aren't this eloquent in your exam answers?”

Frowning, Sparkler smacked her pet’s ass hard with her hand. Partly because she could, and partly because she didn’t want to miss anything important. “Quiet during the lecture.”

Bound to the coffee table, Stonecutter lurched forwards, her ass wobbling a lot. Sparkler had hit her that hard she had left a hand print behind on her behind. “Oooooow...s-sorry, Mistress!”

“I like the sound of that.” Hearing her pet squeal, knowing she was the cause of it, had her so turned on. “You were saying, CB?”

Cloudburst felt quite happy that she knew a thing or two about a thing or two for a change. “Yeah,” she continued, “so, basically, when your sub's had enough, like when it's stopped being fun, they have the safe word, something unrelated to sex, to let you know when to stop, Once it's used, that's it, you stop, no ifs or buts, no questions asked, no judgements.”

“Okay, I can understand that,” Sparkler said, before a thought occurred to her. “Who starts the play? I did this time.”

Cloudburst looked up at Seafoam, as much as she could, anyway, and got a nod from her Master. “Usually the submissive does. Like Master said, the sub is always the one in charge. They can be naughty, what we call ‘good bad’, to earn a punishment. My favourite is to wear panties. Or they can break a standing rule given by the dominant partner.”

“Oh, so I did this wrong?” Sparkler looked crestfallen, like she’d just gotten a B in a test at school as she rubbed Stonecutter’s pleasantly warm behind with a hand. The last thing she had wanted to do was do it wrong. “Who makes the rules...wait, we talked about likes and dislikes, is that like rules?”

“You didn't do it wrong,” Cloudburst reassured her, “Because you asked her if she wanted to do this and Stone said yes. You gave her an out and you respected her decision. That’s doing it right.”

“We talked about how I should be clean and presentable as I can at all times,” Stonecutter put in, trying to be helpful.

“Right,” Cloudburst replied, “so being ‘good bad’ then would be to have some stone dust in your mane, or dirt on your face, anything like that, get it?”

Suddenly, Sparkler had an ‘ooooh’ moment. “Then, I need to pay attention to her so I can catch her being naughty!” This sounded like something she could do.

Seafoam wagged a taloned finger in the air, “Sometimes it’s fun to not catch them and see what lengths they go to get your attention.”

“Yeah,” Cloudburst giggled, “one time I wore panties for three days, Master didn't do anything, so I resorted to wearing a padded bra.”

Stonecutter laughed at that, “kinda obvious, huh, CB?”

“We all can’t have boulders in our tops...” Cloudburst muttered, not a little resentfully. That earned her a heavy clawed hand on her reddened butt, the talons digging into her sore flesh ever so slightly. “OoooOOW!” the pegasus moaned, pouting just a little. “But they're huge, and I got nothing...”

“You have everything I want, CB.” Seafoam leant down and affectionately he nipped her ear, for the moment his voice lost that dominant edge as he comforted her.

Cloudburst still had a pout on her face though, but it was a playful one. She did love it when he nipped her ear like that. “I know, Master.”

Now it was Sparkler’s turn to laugh. “That's why Foamy doesn't have to worry about me chasing you, CB.” She reached forward to squeeze Stonecutter’s massive boobs that were pressed into the quilted blanket under her weight. “I'd rather chase these beauties.”

“Mmmmm th-thank you Mistress!” Stonecutter almost purred, the chubby mare had never been prouder of her hefty melons.

Smirking, Seafoam unfastened the leash restraint that secured his pet to the ottoman. “While the leash worked in a pinch, it is much more suited for collar attachment, and this…” he paused for dramatic effect and, like a magician producing a rabbit from his hat, pulled an amount of rope out of his bag, “This is better for restraint in its inherent beauty.”

Sparkler stared and swallowed with an audible gulp. “R-Rope?”

When she saw the rope, Cloudburst shuddered happily. Though she hadn’t been told to get up, she raised herself to a kneeling position on the floor, her hands automatically behind her back. “Oh yeah…”

“You've worn that at school right?” Stonecutter asked, knowing full well that she had.

Cloudburst nodded, “On days when it hasn't been gym, under my clothes.”

“I like the feel of them under her school hoodie.”

“You’ve worn ropes?” Sparkler paused halfway through releasing Stonecutter from the coffee table. “At school?” the idea that one would wear anything other than the standard uniform for a moment seemed somewhat ludicrous. It was a uniform for a reason! Then, she remembered where she was, what she was doing and whom she was doing it to.

“Yes, at school!” Cloudburst giggled as Stonecutter copied her kneeling position on the floor. “Like, ninety per cent of the time ropes are the only underwear I do wear. Better than panties.”

“At least in a half harness, anyway.” Seafoam interjected, measuring out lengths of the rope with his well-trained eyes. He knew by now exactly how much to use to wrap up his pet. “A full harness can be messy.”

“So, is this the next class?” Sparkler asked, taking the whole demonstration very seriously indeed, “Do I need to take notes?” the bright yellow unicorn watched Seafoam sort the bundle of ropes into varying lengths and thicknesses. She guessed they had different uses, and it all looked rather complicated. That niggling worry that she’d mess it up came to the back of her mind.

“Watch Master dress me, then you have a go on miss moo moo over there,” Cloudburst snickered, picturing Stonecutter in the Nightmare Night costume she had planned for the upcoming event. Stonecutter’s blush was priceless.

Seafoam helped Cloudburst to stand up and, in short order, he finished undressing her. “I'm going to show you the half shell today...for reasons.” The hippogriff commented as he collected his lover’s shorts and tee from her person and set them neatly on the couch. “Sparks, I find hands on is better than notes, but you could do both.”

“Um, ah, Stony?”

Cloudburst, standing completely naked in Fluttershy's living room, her flat chest and shaven marehood exposed without a care in the world, winked at her best friend. Stonecutter, taking courage from the wink, nodded her assent. “I wouldn't mind you being hands on, Mistress.”

More to hide her own blush, Sparkler turned and whispered in the earth pony’s ear, “But you'll be naked in front of Seafoam!”

“I know Mistress, and in front of you. You're all I care about.”

That was enough for Sparkler. If Stonecutter was happy to proceed, so was she. “Okay, so you got more rope?” she asked as she undressed the chubby mare. This did take a little longer than Cloudburst’s undressing, mostly because the unicorn took her sweet time removing her bra, which came off slowly with a lot of (un)necessary groping involved.

“Yes, I have no short...ah…age of rope…” uncharacteristically, Seafoam stuttered as he watched Stonecutter’s DD breasts get liberated from her bra. He hadn’t even noticed the fact that her shorts and panties had been removed as well.

“Mmmmm!” Stonecutter sighed as the air touched her chest and her nipples stood out hard and erect. She didn't even think of covering herself up. Besides, they were long past the point of coy modesty at that point. “Freedom at last!” Cloudburst though had noticed Seafoam staring and she bit his ear. Hard.

“Ooow!” Seafoam exclaimed, “By Novo’s sweet ass, I was just wondering how she keeps from falling over!”

Sparkler wore a very smug expression. “She is a strong mare.”

As Stonecutter’s slate grey fur turned an adorable bright red, Cloudburst giggled innocently. “Ooops, my teeth slipped. My bad.”

“Well, this will make breast bondage a challenge.” Seafoam snickered. “So, a half shell. Shall we?” he passed over a long length of rope to Sparkler, who took it in slightly trembling hands.

Cloudburst, well trained, assumed a 'ready' stance which Stonecutter copied, as loose and ready as she could. “Don't think I'm being funny,” the earth pony said, “but how do you do that when she hasn't got any?” In truth, she had always been curious about that.

Seafoam shot her a look. “I dare you to say that when I'm done. Half shell first, this is the best in body wear. Start with finding the middle of the rope by taking the two ends together and running it through your hands. You burn yourself, you'll burn your sub.”

With the rope in her hands, she didn’t consider using her magic, Sparkler followed the instructions carefully. “So, when do we start tying?” she asked eagerly.

Laughing, Seafoam placed his looped rope around Cloudburst’s neck. “Now. Once the rope is on, you do these little figure of eight knots, called pearls.”

“Those look pretty,” Sparkler also thought he was making this whole tying up process look easier than it was.

While he worked at applying the rope harness to his mare, Seafoam kept a close on Sparkler's work, her rope work and not the subject being tied. His ear was still in recovery from being bitten. He needn’t have worried, for the unicorn proved to be just as adept with the ropes as she had been with the leash. “Now, in a full shell we put knots over the clitoris and the tail hole, but in a half we have the last knot at the belly button. Lot easier to pee that way.”

“A lot easier to be bent over and rutted, too.” Cloudburst added.

Seafoam, for being interrupted, treated his pet to four firm spanks on her already red behind. “Now,” he continued, rope in hand, “You bring the rope around under the tail and we will start making the diamonds on the front.” Though she had admittedly been nervous, Stonecutter watched as Sparkler worked the ropes like a pro, just like she was being shown. When both subs had identical harnesses on them, the hippogriff said, “Now make sure you tie it off in a pretty bow. Then we will move onto the breast bondage.”

At the mention of breast bondage, Sparkler froze, many, many ideas running through her head. She was still for so long that Stonecutter leant in and licked the unicorn’s horn to make sure she was still with them. “GaaaAAAH!” she exclaimed, jumping back in alarm as she was bought back to the room. Unfortunately, she held on to the ropes, pulling the earth pony off balance with her so they fell together. “I'm okay,” she squeaked under her larger lover, “and this is kind of nice…”

A look from Seafoam told Cloudburst not to laugh. “Hard to do rope work laying down, and…um, won't you smoother, under there?”

Right then and there, Sparkler didn’t think being smothered by Stonecutter’s chubby body was a bad thing. “Oh…I don't think so…” Smirking, the earth pony saw an opportunity and squished herself into Sparkler, kissing her nose before heaving herself back up to her hooves.

“If you wanna do the nasty after you're all trussed up, there's some toys in the night stand upstairs!” Cloudburst just couldn’t resist. She then blew a kiss to Seafoam, “we can do it down here, Master.”

Once Sparkler and Stonecutter were back on their hooves, and the unicorn had tied off the rope harness with a pretty bow, the hippogriff continued his lesson. “Diamonds do look good. Here’s some more rope to give that mare of yours a tight bra.”

Sparkler was beet red, and she tried her very best to ignore Cloudburst’s comment. Stonecutter saw her Mistress was having difficulty though, and she kissed and hugged her close to her body. “Ignore the featherbrain. We'll do what we're happy with, okay?” That said though, she did glance up to the ceiling.

Slowly, Seafoam went through the breast bondage step by step, turning the flat chested pegasus into a B cup by the time he was finished and it was all secure. “Done right a mare can wear it comfortably for about six to eight hours.”

Just like she had been demonstrated, Sparkler applied the rope to Stonecutter’s large fleshy breasts. She wound it around the earth pony’s melons and didn’t stop until they had swollen like balloons on her chest and she had given new meaning to lift and separate. By the end of the process she was openly drooling. “Oh my...” Stonecutter glanced down at her tied breasts and she was impressed with the results. She didn’t think they could get any bigger. “Mistress?” she waved her hand over Sparkler's unresponsive face. “Sparks?”

Without thinking, Sparkler did what she had wanted to do since she had first gotten a glimpse of Stonecutter’s ample bosom at the swamp in the Everfree Forest and she latched on to a nipple and murmured, “So beautiful…MmmMMMM!” the earth pony went weak at the knees and even wetter between the legs, if that was possible.

Cloudburst kissed and licked Seafoam's ear, the one she had bitten previously, her hands wandering over his body. “Nice one, teach.”

“I think I've out done myself this time, pet.”

The pale blue pegasus slipped her hands under Seafoam's shirt, playing with his nipples and kissing the back of his neck. “I wasn't kidding about bending me over, you know.”

“I know you weren’t, pet,” Seafoam watched as Stonecutter whimpered out a series of pleasured ‘hmmmm's,’ the earth pony’s eyes closed and one hand holding Sparkler's waist, the other hand groping her skinny ass. “But, I rather think we’ve lost half our audience, and I know you like an audience.”

“You really are a beautiful mare, Stony.” Sparkler breathed when she had to pull away for air.

“I'm your beautiful mare,” Stonecutter kissed Sparkler's lips and smiled, “So, upstairs?”

Seafoam decided it was time to step things up a notch or two. “Undress me pet, and we’ll move on to the next lesson.”

“Yes Master,” Cloudburst dutifully removed his shirt a button at a time then she reverently knelt before him to remove his pants. Hearing that, Sparkler stopped sucking on her own pet’s nipples and she turned to look at what was going on. She saw that Seafoam had a raging erection and she quickly buried her head between the earth pony's tied up breasts.

“Demonstrations are useless without observation, Sparks.”

Stonecutter winked at Seafoam and then she licked at Sparkler's horn to get her to rethink her hiding place as Cloudburst kissed her Master’s tip. Meeping, Sparkler glanced again, only to see Seafoam’s cock balls deep in Cloudburst's mouth – a tell-tale bulge in her throat - and she went back into hiding. “Carry me upstairs, love, please!”

“Yes Mistress,” Stonecutter easily hefted Sparkler up in her arms, holding her close to her ropes and, on purpose she placed the unicorn’s head on her bound breast and carried her upstairs.

In the living room, Cloudburst had her arms behind her back and her lips pressed to the base of her Master’s member. “I don't ravish till the second set of lessons!” the hippogriff called up the stairs.

Held in Stonecutter’s arms, Sparkler’s blush could have well caused first degree burns. Stonecutter just giggled and walked carefully upstairs to Fluttershy's bedroom, where she sat on the bed with a loud creaking sound. “You doing okay there, tomato cheeks?” she asked, placing soft gentle kisses all over her face.

“I don't know why I let those two get to me…” Sparkler said after she had emerged from her chosen hiding place. “Yes, I'm a lot better now. I feel safe in your arms.”

“I'm going to guess it's because you've never done anything like this before and it’s not possible to look silly in front of a book?”

“Humf!” Sparkler snorted, “I can look silly in front of a book!” then, she let out a soft sigh. “I just can't look silly in front of them, or you.”

Stonecutter kissed Sparkler long and hard, her hands roaming to tug up her tee shirt over her smaller breasts. “The only way you could look silly is if you don't communicate and do something you aren't ready for.”

This time, Sparkler didn’t blush. “I'm ready to get undressed.”

“Allow me, Mistress.” Stonecutter gently tugged up her school tee shirt revealing her B cup breasts in her white bra. “MmMmm…”

Sparkler giggled, “I want to play with yours, I don't want yours.”

As she tugged Sparkler’s plaid skirt down, Stonecutter smiled and then, she removed her horseshoes and socks. “I reckon we're both happy with what we've got, Mistress.”

Sparkler licked her lips. “I know I am. Are the ropes okay for you?”

Stonecutter looked down at the ropes wrapped over her fat body and the ones tied around her breasts. “They feel great, Mistress,” she giggled, “I feel like a cow ready for milking.”

Suddenly, as she hadn’t been this far before with anypony ever, Sparkler was crippled by her nerves. “Um…so, I, ah…I looked at a book on lesbian relationships and, um…well, positions, but, well, I don't know if I, ah, do you know?”

Placing a finger on the unicorn’s lips, Stonecutter silenced her before she smiled and kissed her nose. “I happen to know a few ways to get hot and sweaty,” she kissed her once more, “Don't overthink it my love, as much as I love that sexy brain of yours.” Another little kiss landed on her lover’s cheek. “Now, I do believe you wanted to sit on my face?”

Sparkler blushed, because she realised she had been overthinking it and was in serious danger of a meltdown when there was no need. “Um, yes, I'd like that, a lot. Do you really know just how beautiful you are?” she asked, though she didn’t expect an answer, and she pushed her larger submissive back to the bed, or rather she tried to, as without her magic, she wasn't strong enough to force her.

Of course though, Stonecutter played along and allowed herself to be pushed onto her back, shaking her head on the pillows. “You're the only one who's said it, Mistress.”

“I don't say it,” she punctuated her words with a kiss, “I mean it. Now, to give my book learning some feeling!” Sparkler then moved her way up her pet’s body so she could sit on the earth pony’s face. “This is better than science!” Looking up at the unicorn’s shaven marehood, the earth pony drooled at the very pretty sight, then she leaned up and kissed her slit and licked from clit to her tail hole.

Slowly, Sparkler lowered herself down on Stonecutter’s face, placing her pussy right on her lips. “Please make me scream your name. All the romance books say that is the optimum goal…” her eyes went wide and she realised just how dorky that sounded, “I am such an egghead.”

Stonecutter pushed her up slightly so she could speak, “You're my egghead,” she then released her and when the unicorn dropped back down, she was ready and she experimented, kissing around both holes to gauge her Mistress’s reaction. Since it was Sparkler's first time, she went with the flow, content to enjoy the sensations of her lover’s lips dancing around her most private places. Stonecutter spent a moment tonguing her asshole then she concentrated on her snatch, lapping up the middle like she was licking a plate clean.

Riding Stonecutter’s face like a mare riding a rodeo pony, Sparkler was soon lost in the ecstasy of the moment, and she didn't last five minutes. “Stony! I'm…I'm...Gaahhhh!” the unicorn screamed as she reached her climax.

‘I made her cum! I made her cum!’ Stonecutter thought to herself, so proud of herself that she had done that, she reached for Sparkler's hard clit with her lips and sucked on it like she was sucking on a lollipop. With a loud scream that resounded around the bedroom, Sparkler’s second orgasm soon followed. Stonecutter then placed one arm over the unicorn's leg and fingered her nub while her tongue pushed deep inside her tunnel.

After her third Equestria shattering orgasm, Sparkler fell away and tried to catch her breath on the other side of the bed. “I…do...don't…know wh-why I wa...waited so l-long for this…”

Laid on her back, covered in Sparkler's fluids, Stonecutter provided an answer, “Because I wasn't in Canterlot, Mistress?”

Perhaps it was the joke, perhaps it was the moment they had just shared, but Sparkler lost it in gales of laughter. “So, do I taste okay?”

Stonecutter licked her lips, relishing the taste of her Mistress. “Like the sweetest dessert. Um...was I um...okay?”

“Since all I have to base this on are my fantasies and dreams, I’ll say yes! You were bucking amazing!” She couldn’t really argue with having had three orgasms all in the space of fifteen minutes thanks to her marefriend’s tongue. “And I'm glad I taste okay, as I have tasted myself. You were better than great.”

“I love it when you talk all nerdy and sexy.”

“There is one way to shut me up…”

“Oh?”

“For me to see what you taste like.”

Stonecutter liked the sound of that, a lot of a lot. “I would very much like to cum, Mistress.”

“I think I'd like that too.” Sparkler lit her horn and gently parted her pet’s thick legs to reveal her prize, her neatly trimmed dripping wet marehood. The last thing Stonecutter saw of her Mistress was the really big grin on the unicorn's face before she dropped below the horizon of her fat belly and then she plunged her head between those chunky thighs.

While Stonecutter couldn't see Sparkler beyond her belly, a split second later she could feel her and her tongue. “Mmmm Mi-Miiiiistress!” In position, Sparkler went at her task with sloppy abandon as Stonecutter tasted as good as she hoped she would. The slate grey mare groped her own bound breasts as she was eaten out, soon gushing into Sparkler's mouth. “Oh...Ooooooh my...that's soo goood!”

As she was squeezed between Stonecutter's thighs, Sparkler couldn’t hear her, but she loved the bucking of her hips and she continued to lick at all that was lickable. Moments later, Stonecutter squeezed her thighs together trapping the unicorn's head. “Spaaaaaaaarkler!” she screamed as she came, squirting all over the trapped mare’s face.

Eventually though, Sparkler had to come up for air, and she had to use her magic to part the earth pony’s legs because she was still riding out her forceful orgasm. When she surfaced, her yellow face was a mess with her tongue doing its best at self-cleaning. “This is ambrosia!” she gushed, “Should I take notes? I should take notes!”

“Sweet Cadance's horn that was amazing...” Stonecutter breathed heavily, “Notes later. More of that, please!”

Once more, Sparkler dipped her head and this time her hand between Stonecutter’s glistening wet thighs. “Once I get my breath back,” she smiled, using her fingers and thumb to pinch at her lover’s hard clit. “I’ve found another place I feel safe and warm…”

“HNNNNNG! AAaaaaaAAAAAAH!” Stonecutter moaned and squirmed, writhing on the bed as she wetted Sparkler's questing fingers, those wonderful delicate fingers that plunged into her depths, “Th-They did say to look in the night stand, Mistress.” She managed to pant out between moans.

“No.” Sparkler said definitely, sitting up and looking her marefriend in the eyes. “This first time is you and me. I don't need or want any other aid. Another time, maybe, but not this time.”

Slowly, Stonecutter heaved herself to a sitting position, resting against the headboard. “Hey, how sensitive is your horn?” Sparkler blinked at the question and her mouth moved, but no sound came out. Stonecutter didn't wait, she hefted herself to her knees and shuffled over, taking the top third of the unicorn’s horn into her mouth, dragging her tongue all around the ridges.

“Mmmmm oooOOOH, yes I like that…I thought...umm…yeah…” Sparkler found that coherent speech was becoming difficult the more her horn was suckled. Pleasure was shooting directly into her brain. Smiling, Stonecutter went a bit lower, squeezing her lips around the horn. As she sucked hard, Sparkler relaxed and even seemed to purr.

Encouraged by the sounds her lover was making, Stonecutter bobbed up and down on her horn and she even took it all in her mouth, deep throating it like she was sucking on an ice cream lolly. Eventually, the unicorn began to spark. The earth pony sucked all the way up and she went back down, determined to see what sparks she could get. Suddenly, at the point of an orgasm, Sparkler pulled out from her mouth and turned away. Her horn flashed very brightly. She had a really worried look on her face as she looked at the blackened mark on the ceiling. “Sorry...”

Stonecutter giggled, “Feel good, Super Sparks?”

The beet red blush reappeared on Sparkler’s face. “I should have known that would happen. When I massage my own horn, I do that. I need better control.”

Carefully, Stonecutter lifted her lover’s head up with her index finger under her chin. “Don't you put yourself down. We'll learn together, alright?”

“Yeah, about learning, I um, I would like to put my horn in, ah , your tunnel.”

Immediately, after some huffing and puffing, Stonecutter laid back down on the bed and spreads her legs as wide as she could. That seemed like a very good thing to try. “Please do it, Mistress, please!”

Sparkler laughed, “I'll go in for a dip, but I think my tongue is better suited to keep my beautiful marefriend lively.” She lined up her horn and the earth pony mare trembles a little, but she readied herself for what was going to happen. For a day of firsts, this was a pretty big first. Carefully, Sparkler slid her horn inside, adjusting the angle to ensure a smooth entry and she went in until she couldn’t go any more. “How is that? You're so warm and wet, my love.”

“Oh my goodness!” Stonecutter gasped, “I-I can feel every bit of your horn!” Slowly, Sparkler rocked back and forth. She could feel her lover’s hymen and she was super tight. She was careful, in her thrusting, not to break it. Not yet. That was for another time. “OoohMMmmMMMM Sp-Spaaaarks…” Stonecutter reached her orgasm and squirted all over her Mistress’s face.

As fast as she pulled out from her mouth, Sparkler withdrew from Stonecutter’s marehood and placed a second dark scorch mark on the ceiling as she herself climaxed. “That was so bucking hot!”

Stonecutter just whimpered and moaned, “Sweet Cadance...”

Sparkler, her face and mane all matted and dripping with her pet’s cum, crawled up beside her and held her tight. “Stony…I love you.” She couldn’t have imagined, as she was held in those strong, safe arms, that when she opened the door to Stonecutter and Cloudburst the day before, that she’d be here like this, having done what they had just done.

“I love you, Sparks.”
