Simply Coco, Darling!
Chapter Six: Testing the Waters
-By Drace Domino

“Rarity, Mistress, I...I uh…” Coco fidgeted a little, and swallowed a nervous gulp as he looked from side to side around the room. “I’m not...entirely sure about this.”

“Oh relax, darling, it’s entirely safe.” The gentle coo that came from his mistress’ lips helped to calm him somewhat, but it didn’t change the fact that Sunset Shimmer’s bedroom was...not really what he had expected it to be. From talking to the young woman he had expected it to be no different than any other teenage girl’s bedroom; posters of bands and fashion, perhaps a particularly large bookshelf since Sunset was the academic sort. He hadn’t expected a full blown laboratory complete with machines with flashing lights and beeping. It was enough to make him more than just a little nervous, mostly because he was to be the subject of study that day. Once more he nibbled on his bottom lip, and shuffled a little closer to Rarity as he voiced his concerns.

“This...this is really Sunset’s bedroom?” He still couldn’t believe it, despite the fact that in the corner there was a single cot that was messily layered with papers and books. “How does she sleep? Where does she sleep?”

“Oh, darling, Sunset Shimmer hasn’t slept here in months.” Rarity smiled sweetly, and scooped her arm around Coco’s waist. As the elegant young woman walked further into the currently empty room, she gestured from wall to wall with a flared motion, gesturing to countless photos, notes, and studies that Sunset had pinned to the wall. “She stays with Twilight Sparkle now, but keeps this place as her research room. I’m sure that her real bedroom is much, much tidier.” She glanced almost disdainfully at a pile of jumbled papers. “At least, I would hope. I do admit, it’s lovely being neat and tidy, isn’t it? And on that note…”

With that thought in mind Rarity turned to Coco Pommel, smiling as she let her slender fingers reach for the young man’s cute little outfit. She smoothed out the pink collar of his sleeveless blouse, adjusted the frill around his tiny silk gloves, and even knelt down just far enough to straighten out the seams of his sea green nylons. None of those actions were even remotely required when it came to the neat young man’s feminine outfit, but the charm was in the older woman taking the time to do it. She loved to fuss over her lover’s attire, to straighten and primp his clothes and admire just how delicate he could look. Finally her hands rolled down his slender hips to straighten out the miniskirt he had worn that day; the final piece of a cute and flirty ensemble. The entire time Coco just stood there preening and smiling, briefly forgetting the uncomfortable surroundings or the purpose of the test.

“You look beautiful, darling.” Rarity cooed to him, just as her fingers fluffed that soft, silky hair. “I’m sure Sunset Shimmer and Twilight Sparkle will have to wear those ugly protective lenses, considering how radiant you are. Fortunately I can look at you without them, because we shine just as bright.” With that sweet yet slightly cocky tone Rarity giggled, and leaned in to kiss the air at either side of Coco’s cheeks. There was no contact for fear of smudging lipstick across his smooth features, and he simply had to look perfect for his test! Soon she stood right beside her lover with her hand reaching down to take his own; threading their fingers together to give him a firm, supportive squeeze. One more glance over brought a tiny wink from Rarity’s confident features, and she gave him a soothing bit of comfort to help put him at ease. The most important thing she could say, in fact.

“Remember, darling, I won’t let you out of my sight.” She promised. “You are always under your mistress’ eye.”

Coco Pommel, despite his nervousness, was able to meet the slowly opening door face forward and with bravery knowing that much. He let his tiny chest puff out as if his femininity was on full display, and when two figures slipped out from the door he greeted them both with a smile. Rarity was right - those protective goggles of theirs sure were unseemly, but Twilight Sparkle and Sunset Shimmer were clearly there to do research and not put on a fashion show. Goggles and lab coats, clipboards and pencils, the two women looked like they had fallen straight out of a science fiction movie. While Twilight Sparkle fidgeted with the discomfort of wearing goggles over her glasses Sunset Shimmer moved to greet the two, stepping forward and smiling in delight.

“Thanks for stopping by, Rarity, Coco.” She beamed, and reached up her pencil to tap the eraser end to Coco’s nose. While it twitched in immediate response, Sunset Shimmer chimed up in a sweet voice with surprising words. “Well, let’s get right to it. Strip down, and we’ll get you hooked up to the machine!”

Poor Coco’s sudden, surprised gasp was nearly accented with a dramatic faint into Rarity’s arms. Even without it he tightened his hand within his lover’s and gave a look of utter disbelief, cheeks immediately blushing at the sudden request. Strip down? In front of Sunset and Twilight? He was still coming to terms with being naked in front of his mistress! Even if the purpose of the study was research oriented, the idea of being bare in front of either of them was...well...stimulating, but in a more than just a little terrifying way.

“Strip down?” Rarity spoke up for Coco, though she didn’t seem to carry the same level of concern as he did. “Oh Sunset, I didn’t know she’d have to be stripped down for today.” She glanced over at Coco and smiled, teasingly. “Had I known, I would’ve taken the time to powder her little rear to give it that cute little shine.”

As if the blush on Coco’s features couldn’t get any more intense.

“Sorry, Rarity, but Sunset and I decided there isn’t any other way.” Twilight Sparkle spoke up, finally having resolved her issue of having six eyes. She held out her clipboard which showed an indecipherable amount of math and magical symbols; the complex equation that she had worked out for the event. “If we’re to properly judge Coco Pommel’s full magical alteration, we’ll need to get her naked. It’s the only way to see if she has the elasticity to accommodate your arcane endowment!”

“...to see if she can handle your cock.” Sunset Shimmer spoke plainly and simply, and gestured to Rarity’s lap. From the sidelines, Coco Pommel blushed up a storm. It was hard to tell which was more exciting; the discussion about what they were there to test, or the simple fact that Twilight and Sunset addressed Rarity instead of him. His mistress was dedicated to taking good care of him and he trusted her completely; it was somehow soothing to let her call the shots. Just as her hand remained a steadfast bit of comfort within his own, it was relaxing to see Rarity nod along to Twilight and Sunset’s words. If nothing else, he knew that the fashionista would let no harm ever come to him, and that he was there surrounded by nothing but friends.

It was with that thought in mind that Coco Pommel finally stepped up to speak, for the first time taking a stand. His voice rose up amongst the other three girls, and though he sounded nervous there was no doubting the bravery in his tone.

“Then someone get me a hanger.” He puffed his feminine chest out, heroically. “Because this skirt will wrinkle if it’s not properly stored.”

Electrodes were...cold. If nothing else, Coco Pommel learned that as the sticky little things were pressed against his mostly naked body. The process of stripping him down had been a slow affair that Rarity didn’t permit him to have a hand in - she had taken it upon herself to slip him slowly out of his lovely stylish clothing and hang it up to be preserved for later. It was probably best that she had taken the initiative considering Sunset Shimmer and Twilight Sparkle were still in the room watching, if it was up to Coco the young man’s trembling hands likely wouldn’t have been able to hitch against the delicate fabric of his outfit. Thanks to Rarity his shirt and bra were gently removed and he folded his hands across his chest; hiding it as if he had legitimate breasts that needed to be sheltered from prying eyes. For a few seconds he felt a little foolish as he realized that despite his outward appearance he was indeed a boy, and his arms finally slithered away while the two scientists in the sideline whispered to each other. Both Sunset and Twilight were watching with wide eyes behind their safety goggles, studying up and down Coco’s elegant and slender frame as Rarity worked. When her hands went to that skirt they both gave audible gasps, and Rarity’s voice had slithered out like honey past her lips.

“Remember girls, no touching.” She clucked her tongue and wagged a finger, possessively draping an arm around Coco’s waist. “At least...not without my permission, of course.”

And with that, with those words still resting at the back of Coco’s already aroused mind, Rarity began to strip him down further. Skirt and panties were soon set aside though he was permitted to wear his thigh-high sea green nylons; a perfect match to the short lace gloves that still covered his fingers. He stood there as fancy as could be and hiding his growing length behind his silky fingers, whimpering a little as he looked from the two nerdy girls back to his fashionista mistress. The tremble of his lower lip, the slight twitch to his eye...all things Rarity sought out to calm as she leaned forward, kissed his cheek, and petted her fingers down the back of his hair.

“Come on now, girls, time to get her set up.” She invited Sunset and Twilight over, chuckling fondly. “You don’t expect poor Coco to stand here while you pick your jaws off the floor, do you?”

At which point, the electrodes made the scene and sent shivers across Coco’s flesh. They were each attached to tiny suction cups that pressed smoothly against his skin, and Rarity had been very very clear that none of them were to leave an imprint on her Coco Pommel’s precious, flawless flesh. The chilly rubber stuck to his body in seemingly random places; some of which felt as if they were only placed to arouse him, and each of them trailed a wire to one of Sunset’s machines. His belly, his chest, his forehead, even two against either side of his rear. They were placed there to monitor his various responses as the test went on, and there was one final left as Sunset Shimmer stood before him. She clutched that electrode within her fingers, smirking at Coco as the young man still hid his length behind his palms.

“C’mon, Coco, you know where this one has to go.” Sunset cooed, and teased it underneath his vision. “Move your hands, please…”

“W...Well, I...I…” He swallowed once more, and did his best to be brave. When he pulled his hands away he was almost ashamed to expose his length; standing straight out with a glistening dot of precum clinging to the tip. He was embarrassingly aroused and all three girls in the room stared down at it, tilting their heads and looking at it with various states of amusement. Coco, blushing fiercely, suddenly felt rather self-conscious about the fact he was so...plumped. “I’m...I’m sorry. It’s just, with the three of you here, all watching, and Rarity taking off my clothes, I…”

“Don’t apologize, Coco.” Twilight Sparkle spoke up, turning her head away from one of the nearby monitors to smile at him. “Truth be told, the test will work better if you’re at the height of arousal during it. It’ll better let us estimate the effect the magic has on your physiology.”

“It’s better if she’s aroused, you say?” Rarity chimed in, and before Sunset had the chance to place it reached out and plucked the electrode from the girl’s hand. She did the honors of attaching it to Coco; one hand lifting his shaft while the other hand pressed that slightly sticky cup to the spot where his member met his sack. A soft cooing laugh flowed from Rarity’s lips, and she let her eyes flicker towards the other two girls. “Then might I suggest you begin doing what you need to, darlings? I’ll handle sweet Coco’s...research viability.”

“Oh, oh goodness…” Coco’s whimper was the only response he could manage, just as Rarity’s smooth, soft hands began to caress up and over his body. Sunset Shimmer merely smirked as she went over to join Twilight, and soon the two were standing side by side working at one of the monitors. They were keeping a close eye on a dancing light that tracked Coco’s arousal and magical interferences, though it was easy to see that they were both casting sideways glances from the edges of their goggles. It was hard to not look - Coco Pommel was as soft and sweet as anyone, and the idea of watching him get “prepared” by Rarity was almost as exciting to them as it was to the young man himself. As Rarity’s hands slithered around him from behind and she pressed her warm, curvy figure up to his and let her breasts squeeze to his back, he allowed another timid noise to break from his throat. “R...Rarity...they’re...they’re wat...watching…”

“Of course they are, dear.” Rarity murmured sweetly, her lips nibbling at the very edge of his ear. As she spoke her hands crossed over his lap and - while being mindful of the electrode - let her grip move across his shaft. One hand closed around the base as the other lowered even further, teasing his sack with gentle touches and caresses while she started to pump him at a slow pace. A soft chuckle rose from her again as she whispered to her lover, her eyes lost in Coco’s soft, sea green hair. “You’re the most gorgeous specimen they’ve ever had. Is it...okay that they keep watching?”

Coco Pommel had no doubt, not for a second, that if he resisted that Rarity would immediately end the examination. Her love and dedication for her sweet little treasure was absolute, and there was nothing she would force upon him that he wasn’t comfortable with. That side, there was similarly very, very little that he would’ve refused for Rarity. Perhaps even nothing.

“No, they...they can watch.” Coco trembled, and gave a nervous gulp as his member stiffened even further. The blush that ran through his cheeks rushed even further through him; crossing over his small chest and sensitive, stiff nipples. His arms were held out at their sides with fingers squirming from not knowing just what to do, but firmly wishing he could grab onto something to hold himself steady. He swallowed again, and let his eyes close as he started to let the pleasure roll through him. “I’m just...I’m just shy…”

“Don’t be shy, Coco, you’re doing great.” Sunset was quick to comfort him from afar, her eyes more or less transfixed on Coco’s cock as it wove back and forth within Rarity’s fingers. She wasn’t particularly able to turn away from that sight, which was why she sought Twilight to give her a proper update. “Twilight? How are her readings? Still steady?”

“Uh...I uh...yeah, yeah, they’re fine.” Twilight Sparkle murmured in response, without even bother to look. The sight of Coco’s fondled cock was more than enough to draw even those two science nerds away from their research, so utterly transfixed they were on watching it bob and weave with that bead of precum glistening at the tip. Both of them swallowed in near unison, and when they looked over to give each other the tiniest suggestion of a glance it was Twilight that spoke first. She forced her eyes to Rarity, and cleared her throat before speaking. “R...Rarity, would you excuse Sunset Shimmer and I?” She began, biting her lips together as she found her gaze continually gravitating to Coco’s stiff length. “We need to...confer. In the other room.”

“The sight of my beautiful darling is just too much to handle, isn’t it?” Rarity preened, boasting about her lover in nothing but the most glowing of terms. She laughed triumphantly as she pressed one palm flat as it held Coco’s base, purposely swinging it in a wide circle and making it dance for their pleasure and amusement. “Oh, sweethearts, I know that feeling. Try working with her for weeks, watching her bend over to adjust window settings or sneaking in her afternoon popsicle during lunch. I swear, I was about to go simply mad.” She laughed at the memory, just as Coco whimpered and throbbed all the harder. Thankfully, Rarity wasn’t in a mind to tease Coco that evening...now was she of a mind to let Sunset and Twilight suffer. “Dears, why don’t you...help each other out right here? I imagine it would be good for my little treasure to see the full spread of our...condition.”

The look that crossed over Sunset and Twilight’s faces was a combination of arousal, concern, and much, much, much arousal. A sticky, sticky sandwich of delight. Twilight Sparkle’s glasses slipped down her eyes and bumped against the bottom of her goggles, and she immediately had to fidget with them once more to fix them against her face. Sunset Shimmer seemed to keep her composure, although there was likely a raging length within her magical panties.

“You’re...sure?” She asked, the question directed not to Coco, but to the one that he called mistress. “You’re sure Coco’s ready for that?”

“Well, dears, I’m clearly going to tease her to completion within a few minutes.” Rarity cooed, much to Coco’s sudden, gasping realization. “It’d be rude to make her feel like she was the only one. You don’t go to dinner and be the only one ordering dessert, after all!”

With logic like that, neither Sunset or Twilight could argue. After all, they were women of science, and logic appealed to them. Especially if that logic led to the two of them getting intimate a mere three feet away from where the nearly naked Coco was being fondled.

Coco’s eyes were open wide, utterly transfixed at what was going on before him. If his member could get any harder underneath Rarity’s affection it certainly would have, though at that point he was already as aroused as he could possibly manage without fainting. His cheeks were colored with a heavy blush and the nearby monitor connected to the machine was going wild - this cute little thing was at full heat, and he was giving off all the sensor readings he needed to. How could he not be in such a state, when he was being so very blessed by everything around him? His mistress’ warm, gentle, mature fingers moving up and down his body, jerking his length back and forth and even slithering around to tease the entrance of his rear. The scandal of being put on display for people that weren’t Rarity; all the shameful but thrilling delight hiding within exhibition. And finally, just a few feet away...Sunset Shimmer and Twilight Sparkle fondling each other’s long, intimidating equine cocks.

It was the first proof Coco had seen that it wasn’t just his mistress that had been afflicted by the unusual condition, though he had never doubted her words to begin with. Still, seeing them both sticking upright from the laps of those two brilliant young women was...well...it was something else, to be certain. Sunset Shimmer’s was the same amber color as her skin as was Twilight’s that healthy shade of purple, and by now each of them were glistening with a layer of spit from the other. The two girls were trading off; dropping their heads forward to spit, lick and kiss against the other’s shaft, and they were making it a point to never touch their own cock when their girlfriend could do it for them. From time to time they looked towards Coco Pommel, whispered amidst themselves, and groaned in pleasure as they sat a little bit closer and squeezed each other’s length with more intensity.

“W...What are you whispering about?” Coco could only finally manage to find the strength to speak, though it was with great duress as Rarity squeezed and fondled him. Those lovely fingers danced over him like threads of silk and kept him in an intensely aroused state; so deep and hard that his tip was leaking a thin line of pre in a steady rate. Rarity; ever with an eye for detail, scooped her palm underneath that thread to collect it and return it to Coco’s length, smearing it right back over his head. Though that pleasure that waved over him was nearly enough for him to ever forget he had asked a question, Rarity was still kind enough to kiss the back of his neck and answer for the two girls.

“They’re just whispering about what happens if the test goes well.” She cooed; her voice low enough so that only Coco could hear her words. With a small force she rolled her hips forward and let her lap grind against Coco’s rear, and though the magical panties hid her member Coco could simply envision his mistress’ erection in that moment. Thick, and juicy, and throbbing, and...he trembled in place, and swallowed a beat of hunger as Rarity whispered further. “They’re whispering about...what it’ll be like when I get to make love to you properly. When I get to sink inside of you...show you what a beautiful girl you are when you’re taking your Mistress all the way down.”

Those words flowed forward like honey, and poor Coco was caught at an impasse. Did he close his eyes and grind forward into Rarity’s hand, pretending that he was taking her length up his backside right now? Or did he simply stare ahead, watch as Twilight Sparkle and Sunset Shimmer teased and licked each other in greedy glee. Either option would make him quake with orgasmic bliss before too long, but it would require far too much attention than he had in that moment to do both at the same time. Finally he whimpered, and as his member slapped into Rarity’s open palm he let his eyes fix on the two scientists.

...he could fantasize about letting Rarity thread his rear any time. It wasn’t everyday he got to see these two having so much fun!

Twilight Sparkle’s lips were wrapped around the very tip of Sunset Shimmer’s length, but she was only barely able to keep it that way thanks to the wide, flat head of the other girl’s equine length. Her tongue teased back and forth across the tip and she was readily drinking in what flavors she could - swallowing constantly to make sure none of her lover’s precum was wasted. While Twilight worked Sunset Shimmer rewarded her with a hand wrapped around her purple shaft, pumping it slowly up and down from the tip down to the impressive base. Seeing the two girls kiss and fondle each other’s members was enough to make Coco quiver in place even without Rarity’s touch; so many things were spiralling about in his mind. Was that what he looked like when he was servicing his mistress? Was she larger than these two girls? Would it really be possible to one day use his unique power to accommodate something so very, very big? He tightened his throat with a steady gulp, but that only made him crave some of that taste that Twilight Sparkle was enjoying. If only his Mistress Rarity would take her own length out, if only she’d feed it to him right then and there...oh, the things Coco Pommel would do for his mistress in front of those two brainy girls. There was nothing he would hold back, nothing he would deny her.

With a quiver of pathetic pleasure Coco Pommel looked over his shoulder, hoping that in some way he could possible convince Rarity to bend him to his knees and let her massive length brush past his face. The steady smile on the fashionista’s lips told him it wasn’t going to happen - at least, not right there in front of her friends. Her smirk was too knowing and her look too coy, not to mention the fact that her hands were by now working faster and faster against his length. She had cupped Coco’s sack with one hand while the other now jerked him steadily back and forth, and as she continued she whispered urgently against the back of his neck. Her voice was sharp and precise; the command of a mistress that didn’t want her beloved treasure to miss a thing.

“Watch! They’re going to pop soon, dear, you don’t want to miss it!” She beamed, giving her full approval for Coco to simply stare at those other two girls while they worked. Both Sunset and Twilight were still wearing their goggles, which Coco Pommel would soon learn was a good thing considering what came before too long. By the time the girls both hit their peak they had repositioned themselves to fold their legs together; sitting nearly belly-to-belly with their members pressed close. They were working together now, jerking their dual cocks off with four total hands, and a few times they both dipped their mouth down to give a lick across both large flat heads, only to come up with more blended precum to share with her girlfriend. It was intimate, sticky, beautiful, and...wonderfully, wonderfully dirty. Coco Pommel practically ached in pleasure as he watched it, utterly fixated by their smiles, their cocks, and the fond love between the two. And when their peaks finally hit Coco was the only one surprised at just how...intense it was. There were sudden bursts of cream jetting from thick and twitching members; the staggered cries of two young women clinging to each other. Splashing white spunk that struck the consoles, the goggles, and lab coats, and two slick lengths that were utterly impossible to control. The cum that seeped between the two girls was utterly slathering in nature, striking the bottom of their chins, the lower half of their faces, and most importantly...their smiles.

Coco was already overwhelmed, but when he saw Sunset Shimmer and Twilight Sparkle lean in for their first cum-covered kiss of the evening, it was simply too much. He could handle being naked in front of them. He could handle watching them suck each other’s cocks. But...the two girls being adorable and loving while covered in cream? He was a sucker for soft affection, and it was just too much for his Rarity-guided member to handle. In the grand scheme of orgasms in Sunset Shimmer’s room that night, Coco Pommel’s was definitely the smallest. His burst of cum was tiny compared to the copious amount the two scientists unleashed, and his arc was impressive but not mammoth like theirs could be. That said...it had the most impact as Coco’s hips flared forward, his voice cried out, and his member squirted a sudden burst of cum that went flying high, high, high in an arc...only to splash squarely where Twilight Sparkle and Sunset Shimmer’s sticky lengths rested against each other.

A sudden splash of white on an already covered pair of cocks...it was easy to go unnoticed, if they hadn’t all see just where it came from. Sunset Shimmer and Twilight Sparkle giggled eagerly as they soon took turns leaning down to lick some of it up; claiming it as their own. Rarity had told them that they couldn’t touch Coco just yet, but as soon as his spunk landed on them it was considered their property! As the two girls looked up once more and kissed with the faintest hint of Coco Pommel cream on their lips, Rarity’s voice slithered forward against her young lover’s ear.

“...bullseye, darling.” She cooed, and flexed her own sticky, cum-covered fingers. Whether she was complimenting Coco Pommel for his arc or herself for guiding that length towards a destination it was hard to tell, but in reality it was probably both. She kissed Coco’s cheek as she began to walk, kneeling down only to scoop up Coco Pommel’s panties as she did so. For the moment the young man was wondering if he’d be asked to get dressed again, but when Rarity kept moving past him his knees quivered with weakness and arousal.

“Girls, you may use this to clean your cocks off before tucking them back inside.” She chimed in, offering that tiny piece of Coco’s panties over to their shared grip. Her other hand - the one thoroughly coated in Coco Pommel’s sticky white cum, stretched forward with her fingers spread and her palm turned to the ceiling. “And you can enjoy this as a treat...I can always make more any time I like.”

She said all these things with a dominant air to her voice, and she gently made eye contact with Coco as Sunset and Twilight worked. The two scientists had more or less completely abandoned the research for now; staggered as they were by the arousal in the air. They were sucking on either side of Rarity’s hand to clean away the traces of Coco’s cum, and their hands were both rubbing their slick, wet, creamy lengths off in Coco’s increasingly dampening panties. Rarity didn’t even watch the display - she had seen those two be sluts for one another many, many times in the past. Her only focus in that moment was Coco, her beloved treasure, and the blush rushing over his features.

“Coco Pommel, dear.” She finally spoke up, flexing her fingers back and forth once the hungry scientists finished cleaning it. “Fetch your panties and get dressed, love. I believe...we should go for a ride together.”

Coco Pommel, already a bundle of arousal and desire, simply nodded gleefully. After all, those electrodes were still cold...and the look in his mistress’ eyes was nothing but pure, unadulterated warmth.
