Syn and Celestia were making their way towards Fluttershy's cottage after just recently splitting away from Luna and Rook. Celestia insisted that Syn and her walked alone. She could easily handle herself if need be. She was, afterall, a goddess.

"It's a beautiful day, isn't it?" Celestia said offhoof. Syn looked around a moment, noting the clouds being particularly fluffy today.

"Yeah, it is," Syn agreed.

"I think Fluttershy will take a liking to you, Syn," Celestia commented.

"How so?"

"Well, she's very shy and timid. I think she'll enjoy a stallion that will take charge. Not to mention the fact that you're quite handsome."

"Heh, thank you. From what I've heard about her, she sounds very nice."

"Well, she is the element of kindness," Celestia giggled.

"Hurt her and I'll end you," she murmured in a sinister voice.

"What was that?"

"I said we're almost there." It only took a couple more steps before they reached the grassy bridge leading up to Fluttershy's dainty wooden door. Celestia stepped ahead of Syn and knocked on the door. Seconds later a cute yellow mare appeared at the open door.

"Oh, you're here," she said with excitement, "please, come in." Syn and Celestia stepped inside, the scent of nature hitting their nostrils instantly.

"It smells great in here," Syn said after taking a big wiff.

"Oh, thank you...ah..." Fluttershy stammered.

"Syn, pleased to meet you, Fluttershy," he extended a hoof towards her. She gingerly shook his hoof. She looked up at him for the first time, and gazed upon his beautiful eyes. He looked back at her with a smile and Fluttershy quickly turned her head away, blushing.

"We're going into your bedroom, I assume?" Celestia asked. Fluttershy simply nodded and turned towards the staircase saying,

"Yes, I don't want to scare the animals." Fluttershy led the way up the stairs and into the bedroom. It was more like an attic than a bedroom. You could see the room from the bottom of the stairs, seeing as how there was no doorway. The small, wood framed bed was directly in front of them.

"Uh, that's a little small," Syn pointed out.

"Not a problem," Celestia said and her horn glowed. Almost instantly she made the bed grow twice the size it was originally.

"That works," Syn stated. Fluttershy noticed she left the window to the right of her bed open so she walked over to it and closed it.

"I should mention, the safeword is apple," Celestia said. Syn and Fluttershy nodded in understanding.

"Okay, I'm ready," Fluttershy said. She returned her gaze back to Syn's eyes causing her to blush again.

"Are you sure Fluttershy?" Celestia asked. Fluttershy looked at the ground and said,

"I-I'm sorry. It's just that...he has really pretty eyes." Syn chuckled at the compliment.

"Yeah, I get that a lot. Your eyes are pretty too. You can look, I won't bite," he promised. Fluttershy slowly turned her head upwards and their eyes met. She was still hiding behind her hair somewhat, only one eye being exposed. Her heart fluttered as she tried her hardest not to look away. They stayed this way for a few minutes, staring at each other. With time, Fluttershy got more comfortable and slowly revealed herself to him. The two held their unwavering stare for a little longer and Syn took a step towards her. She did the same and they repeated this until they were face to face. They could feel their breaths brush against each others faces.

"I think I'm ready now," Fluttershy whispered. Syn shot her a quick smile, leaned in, and kissed her neck gently. Fluttershy quietly gasped and closed her eyes, letting him take over. He made sure to be extremely gentle as he kissed her neck in several different spots. He whispered in her ear,

"Let's get on the bed." She immediately obeyed his command and sat on her haunches on the now blanket-less bed. He climbed on it as well and looked down at her. She looked back, her eyes full of want and passion. His gaze panned down even lower to find that her teats were unusually large. Just the way he liked them. He leaned down and continued his barrage of kisses on her neck and shoulders, Fluttershy constantly gasping and whimpering. His kisses trailed downwards to her chest, then her ribs and stomach, and then he reached her boobs. He licked and sucked on each nipple tenderly, Fluttershy shuddering above. After some time, he started to move his head even lower.

"W-wait," Fluttershy stammered. As she stood up from the bed Celestia had reappeared, a look of concern on her face.

"I want to use a toy," Fluttershy explained. Celestia nodded and disappeared again, smirking. Fluttershy trotted over to a nearby dresser and pulled out a dildo and a bottle of lube. She set them on the bed and told Syn,

"I want you to put this in my...butt...as you eat me out." A grin slowly emerged on Syn's face.

"Sure thing," Syn said nonchalantly. Fluttershy got herself onto the bed on her back again and waited patiently. Syn squirted some of the lube onto his hoof and got down low. She hesitantly lifted up her legs, exposing herself. Right away he noticed a piercing attached to Fluttershy clit. It was a hoop with a little butterfly design on it.

"I didn't think a mare like you would have a piercing like this," Syn said with a chuckle.

"Oh, I'm sorry! Do you not like it? I only got it because I got drunk with Rainbow Dash once and she talked me into it," Fluttershy said, feeling rather distressed.

"I don't mind it at all, just thought it was interesting. Anyway, I'm going to rub it on now. Ready?" Syn asked the blushing mare. She nodded and Syn then proceeded to press his hoof into her asshole. Fluttershy's body tensed for a moment.

"C-cold!" she exclaimed.

"It'll get warm," Syn reassured her. She knew that already, having done this many times herself, so she just focused on relaxing. Syn teased and played with her asshole, running his hoof around and inside it several times. After she was properly lubed, he applied lube to the butt plug. The plug was about four inches long and about an inch thick. It was made of pink plastic and the bottom of the plug had a heart shape. He gently pressed it against her awaiting hole, teasing her.

"P-put it in, please," Fluttershy begged. At her request, he pushed the first two inches inside. He waited a moment so that she could get used to the foreign object, then pushed the rest inside.

"How's that?" Syn asked.

"G-good," Fluttershy replied. He went back up and kissed her neck.

"I'm gonna eat you out now," Syn whispered in her ear in a surprisingly deep voice.

"O-okay," Fluttershy whispered back. He returned to her crotch and licked his lips. He practically plunged his mouth onto her pussy. He traced the alphabet with his tongue on her pussy hole.

"Syn...it feels so good!" Fluttershy cried out. Syn smiled to himself in satisfaction. After tracing the alphabet twice he moved his tongue up and onto her pierced clit.

"Ah...right there," Fluttershy moaned. He flicked her clit over and over, each flick elicited a quiet and cute moan from Fluttershy. She reached down and placed a hoof atop Syn's head, ruffling his cream mane.

"H-harder," she whispered as she pressed his head harder onto her clit. He did as asked and pressed his entire tongue onto her clit, her piercing slightly getting in the way, but he was happy to please her, for he was full mast at this point. It was pressing against the soft fabric of the sheet of the bed and precum was leaking. Despite this, he was focused on pleasing Fluttershy.

"Keep g-going. I'm gonna cum soon...ah!" Fluttershy spat out. Her body was starting to tense up in preparation for her orgasm. Her ass was clenching the butt plug tightly and beads of sweat were dripping off her brow. Her eyes were shut tight and her hooves were clamped onto Syn's head. It was heavenly. It didn't take long for her to reach her orgasm and her pussy spewed out love juices onto Syn's face. Once her oragasm was completed, he pulled back. His mouth, chin, and even some of his nose was covered in her cum.

"O-oh, I'm sorry! I made a mess..." Fluttershy whimpered.

She is so adorable! Syn thought to himself.

"I don't mind. It let's me know you enjoyed it. Well, that, and all the sounds you made," Syn joked. They both shared a chuckle and Syn cleaned his face. Celestia appeared before them, some potions on the ground in front of her.

"I hate to interrupt you two, but you forgot these," she said lifting them with magic.

"Syn, you get two, and Fluttershy gets one. Fluttershy, take yours first," she explained. Fluttershy firmly grasped the potion in her hoof. It was pink and a little bubbly. Syn kept his potions next to him, one looking almost like mud and the other looking like milk. Fluttershy popped the cork off her potion and took a whiff. It strangely smelled like watermelon. It tasted like it too, Fluttershy discovered after drinking it whole. They all sat and stared in anticipation. Suddenly, Fluttershy's body became extremely sensitive. She could feel every crease of the bed sheet, every drop of the lube in her ass, and every slight change in the air.

"So, how does it feel?" Celestia asked.

"It's like...I can feel everything," Fluttershy whispered.

"Is it good?"

"It's really...nice."

"Well then, Syn, you're next. Drink the brown one first," she said with a knowing grin. Without further questioning, he drank his potion. The potion did its thing almost instantaneously and another cock grew above his current one. It was, seemingly, an exact copy. He reached down and touched it.

"Two dicks? Strange, but, this should be interesting," Syn chuckled.

"Oh...my," Fluttershy said. Celestia gave Syn a somewhat seductive look.

"Now, the other potion, then you may begin," she said as she vanished.

"Alright," Syn mumbled before he drank the next potion. A few seconds passed and he felt his ball sack growing and filling with cum. A sack that was once the size of a softball was now the size of a soccer ball. Fluttershy looked at it in excitement.

There's gotta be a lot of cum in there...yay, she thought.

"Uhnf. Kind of heavy," Syn grunted, "so, how do you want to do this?"

"Uh, well, you could put one in my pussy and one in my ass. I gave myself an enema before you came, so, if you want to, um, do that, that would be, um, nice," she whispered. Syn's ears perked up.

"Well, why don't we do that then?" he said, bringing his attention to the plug still in her ass. He leaned down and took the end of the plug in his mouth and slowly pulled it out, throughout the act Fluttershy was gasping, feeling the plug rub against every groove inside of her. By the end she was practically panting. He placed the plug on the far side of the bed and grabbed the lube. He made sure to lather his cocks in lube while adding some to each of her holes.

"Here, let's change positions," Syn suggested. He gestured for her to turn around and have her face down and ass up for his viewing pleasure. She flicked her tail to the side and he saw that her pussy was swollen and in need of pleasure and her ass was slightly stretched and ready to be penetrated. Both of her parts were glistening from both her own arousal and the lube. No doubt, this was quite a sight.

"I-is this what you want?" Fluttershy asked, already taking deep breaths from her increasing anticipation.

"This is perfect, Fluttershy," Syn responded as he prepared himself to enter. He pressed the top cock onto her ass then the other against her pussy. He rubbed them with his dicks, teasing her. Fluttershy was already beginning to go crazy, shaking and loudly moaning.

Why couldn't I have gotten that potion? Syn asked himself. He pushed the thought to the back of his head and pushed his other heads inside of each of her holes. She squealed as she felt his cocks plunge into her, feeling every vein and bump grind against her inner flesh. He then gradually pushed the rest of himself inside. Once he hilted, Fluttershy cried out in pleasure and trembled.

"Syn, I-I came," Fluttershy whimpered. Syn smiled and chuckled, feeling proud of the accomplishment. He pulled out and pushed back in again, eliciting another loud moan from the pegasus below. He paused for a moment, relishing in in his own pleasure from both his dicks. He could feel each cock grind against each other through the thin veil of flesh between her pussy and ass. He slowly pulled out and then quickly shoved himself in, surprising Fluttershy, causing her to cry out. Sweat was trickling down her slender body as her pleasure increased incrementally with each passing moment. Her feminine liquids were leaving its mark on his cock and started to trickle down her legs. Her breath was ragged and heavy and she could barely have a coherent thought. She was in pure ecstasy and yet Syn was barely moving.

Syn decided now was a good time to start pumping his cocks inside her. Syn, being extremely horny and impatient at this point, began his quest to pound her love holes very quickly. Her tits were swaying forwards and backwards and lightly slapped against his balls.

"S-so good, ahn!" she somehow managed to moan.

"Hng, let's make it, ugh, better," Syn announced with confidence before pushing himself to go faster. He stayed at this rate for some time while his orgasm was building up. He then decided to change positions again in order to last a bit longer. He moved Fluttershy so that she was laying on the edge of the bed and he lifted up her legs, her being in an almost coma-like state from the intense sensations. He got in between her legs and rested his top cock in between her breasts while pressed the bottom cock's tip inside her pussy. He spit on his top cock for just a little extra lubrication and squeezed her tits together with both of his hooves.

"Are you doing okay, Fluttershy?" Syn asked. She let out a quiet moan.

"Repeat that?"

"Hnn..."

"Fluttershy?" Finally Fluttershy took a deep breath and managed to say,

"I'm okay, please, do me, it's so...wonderful." Not wasting any more time, he plunged himself into her pussy and began to titfuck her simultaneously. Fluttershy looked up at him with eyes half open, face a deep red, and body glistening with sweat. Her chest heaved up and down and her body shook. Syn continued to pound away at her wet flesh, feeling his climax build itself inside him.

"Fluttershy...I'm gonna...!" was all Syn could muster. A few more moments passed and Syn rushed to his finish. His cocks practically turned into super soaker water guns, the top cock gushing out huge streams of jizz all across Fluttershy's body. It covered her face, some of her hair, her chest, her wings, and anything else in the blast zone. Meanwhile the bottom cock was filling her pussy to capacity and then some, the semen pooling onto the bed. In the end, Fluttershy had practically taken a bath in the stuff. However, it wasn't the end. Syn's genitals still weren't completely satisfied; still swollen and hungry for more pleasure. So, he did the only thing that made sense. He climbed atop Fluttershy (making sure not to get cum on himself, of course, though that was nearly impossible) and aimed both of his dripping cocks carefully.

He then pushed both of them into her cum glazed pussy without an issue. A guttural moan erupted from Fluttershy, causing Syn to stop in his tracks.

"Fluttershy?" He asked with pure kindness and worry in his voice. There was a pause, then, Fluttershy whispered without opening her eyes or moving any other muscle,

"Don't stop." Syn, figuring that was a solid yes, began to jackhammer her tight pussy, which was somehow able to contain two cocks at once. The two loudly moaned and groaned almost in unison, the sounds of their sex flooding the room. Fluttershy at this point was a blubbering, sweaty, twitchy, cum-drenched mess, while Syn was a sex-crazed deviant. Fluttershy was orgasming almost non-stop. It was almost too much for her. Luckily, it wasn't too much of an issue because Syn was already getting close to finishing again.

"Guh, here I cum...Flutter--!" He cut himself off with a grunt as his final thrust made its way into her spasming body. He came buckets upon buckets inside of her to the point where just about all of it was coming right back out and onto the sheets and floor. Fluttershy, her body extremely fatigued, could only lay there seemingly comatose as his cum filled her. Eventually he pulled out, about another bucket of cum following suit. Finally, his balls had been emptied yet retained their abnormal size. Syn climbed atop the bed and positioned his cocks in front of Fluttershy's face.

"Clean them," he ordered as he leaned in closer, his cocks now smearing the cum on her face. She craned her neck upwards and weakly sucked and licked the cum off of the softening members. After doing this for a while she stopped, not knowing if she actually got everything off or not due to all the cum still covering her from head to tail, and tried to relax herself as her body began to recover from the ordeal. Syn mimicked her and laid beside her. They both breathed deeply in unison, their hearts attempting to return to a regular beat.

Just then, they heard a noise. A whimper?

Is that...? Syn thought as he sat up. His suspicions were correct as Celestia slowly became non-transparent. She was on the ground, her face was red, her eyes were shut tight, and her legs were wide open with a hoof in between caressing her soft folds. She was cumming. Syn continued to watch this spectacle happening before him. In a matter of seconds Celestia came as her body convulsed. She took a deep breath and said,

"Good show you two!" She quickly recomposed herself and stood up. She looked down at Fluttershy. She was still twitching about.

"Oh, I should probably fix her," she mumbled to herself. Her horn glowed and an instant later Fluttershy was fully recovered. No more cum covering her (though the cum inside her was left untouched), no more twitching, no more convulsing. She sat up, somewhat dazed.

"What happened?" she asked in a whispy voice, "I remember we had sex, but I think I blacked out."

"Yes, you did indeed have sex. What's the last thing you remember?" Celestia asked.

"Syn...putting both of his dicks inside of my...vagina."

"Interesting," Celestia quipped, making sure to write down a note.

Tone down the pleasure potion!

"How was it for you, Syn?" Celestia asked.

"Wonderful," he breathed.

"That's great! Here, let's tidy up," Celestia said before her horn shined once more. The room and Syn's genitals were returned to their original state.

"I'm sure Twilight will be glad to hear about this," Celestia said to herself. Fluttershy looked over at Syn.

Oh my...I'm going to have his foals, she happily thought.

"Now that the test is over, I think it's time for me to join in on the fun," Celestia said, winking towards Syn. Yet again, her horn lit and her underside glowed for a moment. Syn took a glance underneath.

"Uh, Celestia, not to sound rude but..." Syn said, his voice tapering off.

"Yes?" Celestia asked, tilting her head down low and giving Syn a seductive glare. Celestia's tits

"So, have your tits always been that big?" Syn finally asked. Celestia giggled. Celestia's tits were so big they

"That was blunt. But to answer your question, yes. I just hide them. I can't have them swinging about all the time, you know? But it's always nice to just...unwind every now and again. I figure this would be the perfect time to do so," Celestia said as she sauntered her way closer to Fluttershy.

"Um, Princess?" Fluttershy stammered before Celestia licked her lips and pounced on her, their lips meeting. Fluttershy's eyes opened wide in shock but quickly relaxed as Celestia embraced her. Their tongues jumped and scattered about in each others mouths like fish out of water. Fluttershy let Celestia take the lead to this tongue twisting tango. Celestia and Fluttershy moved themselves onto the center of the bed to continue their heated makeout session. Meanwhile, Syn decided to take a look at what else Celestia brung. He slithered over to the back, his balls having somehow regained its cum and swinging low at his knees. Inside the bag was a potion that had a plastered on label that read "girth potion". The potion was the color of the sun, bright and radiant. There was also a note, written on fancy parchment, that explained the intended effects of the potion. It was created to, obviously, make a penis girthier.

Without much thought he chugged it down and within seconds the lemon tasting potion worked. His cock was now almost twice as thick as it was previously! He looked inside the bag one more time and discovered another pleasure potion. He glanced back over at Fluttershy and Celestia and their pussies were stacked on top of each other and in plain view. Syn had an idea. He popped open the potion and let a few drops of it trickle onto his hoof, then onto his droopy dick. He began to touch himself with the pleasure potion covered hoof while spectating the two lovers.

His cock was instantly ten times more sensitive than it was before. Just the slightest touch of his cock gave him ecstasy.

"Holy shit," he mumbled as he continued to sensually stroke himself. Celestia opened one eye and looked towards Syn, noticing his erection now growing. Celestia paused the makeout session between Fluttershy and her.

"I see you've grown quite a bit. Took more potions I assume?" she asked as she climbed off the poor and horny Fluttershy. Syn chuckled and whispered, feeling confident,

"Yeah, would you two mind helping me out?"

"Gladly, kind sir. Come, Fluttershy, we must help our friend," Celestia commanded.

"O-okay," Fluttershy muttered in response as she slowly picked herself up. Syn leaned back against the wall, his dick thick, hard, and damp from using the various potions. Celestia, being perhaps entirely too eager, had already positioned herself face to face with his penis. He could feel her warm breath gently caress and surround him. He grimaced and gasped at the sensation. Celestia giggled,

"I haven't even laid a hoof on you! Does the potion work that well, or am I that arousing?"

"A bit of both," he said under his breath.

"Excellent," she whispered. Fluttershy stayed back and was content with just watching. Her face and pussy were slightly red from the excitement of the moment. Celestia noticed this and decided to take Fluttershy out of her comfort zone once again.

"Fluttershy, he needs both of us to help him."

"Oh, I know. I just, um, want to watch first, if that's okay," she said with a smile. Celestia shook her head and sternly said,

"That's not acceptable. You've done this before, Fluttershy. Why so anxious all of a sudden?" Celestia asked as she gently rubbed Syn's tip with the end of her hoof.

"Do you need to be warmed up a bit more, perhaps?" Fluttershy tentatively nodded her head.

"Very well. Syn, lay down," Celestia commanded. Syn did so without question, knowing where Celestia was taking this. Celestia guided Fluttershy towards Syn's face while she sat on Syn's dick. Her pussy lips were practically giving Syn's cock a sloppy hug and her voluptuous breasts let themselves lay atop his waist. Fluttershy remained hovering above Syn as she faced away from Celestia. Syn gasped from Celestia's teasing while gazing up at Fluttershy's tight asshole and swollen pussy. Syn licked his lips in anticipation.

"I-I don't know..." Fluttershy whispered. Syn took it upon himself to grab Fluttershy and pull her down onto his snout. Fluttershy squealed, frightened by the sudden aggressiveness. Syn took pleasure in the feast that was Fluttershy's pussy. Hungrily he lapped at the quivering wet lips above him while Celestia rocked her firm body on his slick cock.

"S-Syn...that feels...so nice, ah!" Fluttershy moaned.

"Hah, your dick feels pretty great too, Syn," Celestia added. Syn could only grunt in response. Syn was now drinking Fluttershy's juices as they dripped out. Celestia hadn't even put it in yet and already he was feeling that familiar pressure down below. Syn tried to push Fluttershy off to warn them. He failed in doing so, Fluttershy now relentlessly grinding against him.

"I'm c-cumming!" Fluttershy screamed out, and cum, she did. Fluttershy came directly into his mouth and he gladly swallowed it all. Fluttershy shook and took quick breaths, trying to regain her composure. Meanwhile Syn was almost gasping for air. Without holding back, he slapped Fluttershy's ass to get her attention. Obviously, it worked.

"Ow! Syn!" Fluttershy yelped. She quickly stood and looked down at Syn as he took a big gulp of air.

"Oh! I'm so sorry!" Fluttershy now apologized. Syn merely nodded in response, lacking the air to speak at the moment.

"You were close, weren't you, Syn?" Celestia asked, seeming to already know the answer. Celestia chuckled,

"Now, Fluttershy, will you help me in finishing Syn off?" Celestia asked Fluttershy, who was still recovering. Like Syn, she could only manage to nod her head.

"Good," Celestia smiled as she lifted herself off of him.

"Let's relocate to a more comfortable spot," Celestia suggested while heading towards the bed. Syn rested his body against the pillow-laden headboard, his unnaturally thick cock swinging all the while. Celestia and Fluttershy then took their places; eye-level with his dick. The girls took a quick glance at each other then looked up at Syn with lust in their eyes. Their gaze unwavering, they both lashed out their tongues and began licking his dick up and down, tasting the remnants of Celestia's wetness. Syn relaxed himself as he let the duo do their work.

"So good..." he mumbled to himself. The girls started taking turns between licking the head and licking the shaft, working as a team. Then, Celestia decided to take the lead by taking the head in her mouth. Celestia moaned in satisfaction and Syn moaned in pleasure. Fluttershy moved down to service his balls and began to slowly drag her tongue across the surface.

"Mmm..." Celestia moaned, then she lifted her head off his dick.

"Are you enjoying this, master Syn?" she seductively whispered, her lips grazing against the head with each word that flowed past her lips. He was at a loss for words, so he simply nodded.

Master...I could get used to that! he thought. Fluttershy took her turn and immediately shoved herself halfway down his thick dick. She grunted when she felt it hit her throat.

Heh, looks like she's not being shy anymore, he thought humorously. He placed a hoof on her head and closed his eyes, relishing in the pleasure. Celestia began licking his balls and attempted to fit them in her warm mouth but to no avail; they were way too big. She instead fondled one testicle while licking the other, her spit dripping off her chin. Already, he was getting close to completion, his legs and groin tensing up. He announced this to the mares and In response Fluttershy and Celestia fondled his cock with their hooves while licking and sucking him off, their eyes wide and glowing in anticipation. He looked down into their eyes, the image now burned forever into his mind of the two illegally beautiful mares finishing him off.

Unsurprisingly, he came seconds later, his churning balls now emptying their load onto their faces and manes. Once he was finished, he closed his eyes and let his body sink into the bed, smiling all the while. Fluttershy and Celestia then looked at each others cum covered faces and giggled. They then returned their attention to the recovering gentlecolt.

"So, how was that, Syn?" Fluttershy asked with half lidded eyes.

"Fucking amazing," he replied. The mares laughed and gazed at each other again.

"I think cumslut is a good look for you, Fluttershy," Celestia said.

"Oh...my...th-thank you," Fluttershy stammered as she blushed, surprisingly not taking offense to that comment and instead feeling sexy and desired.

"So, do you think you could go again, Syn?" Celestia asked. Syn's eyes opened and he gazed up at the two cum covered mares.

"How could I say no to that?" he replied, his cock already beginning to harden again at the thought.

"Excellent," the word slithered out from Celestia's tongue as she turned away from him, lifted her tail, and displayed her good bits to him.

"Put it in my ass, Syn," she whispered, indifferent to the cum dripping off her chin and onto the blanket. Fluttershy just played with the cum on her face, quietly giggling all the while.

"With great pleasure, Princess," Syn said deeply. In no time at all he prepared himself for entry. He pressed and rubbed the tip against her tight, pink asshole, smearing the cum from his cock. Without further ado, he pushed inside, her ass enveloping him. His dick now practically in a vice, he halted, enjoying the sensations of her ass tightening and loosening up over and over.

"So big...!" Celestia breathed. Syn patted her ass and chuckled, feeling prideful that his cock could please her.

"Your ass is quite big as well, Princess," Syn grunted as he inched his way forward, "and tight," he added. He then methodically, but carefully, pounded her mighty posterior. Each time his groin made contact with her ass, it jiggled and shook. It was so hypnotizing, intoxicating, that he could not tear his eyes away from it. He began to show his enthusiasm by quickening his pace. Now, not only did her ass jiggle, her whole body shook as well. Her mane slapping her in the face every time he pushed her forward, then flowing away from it as he pulled her back. Her moans, loud and uncensored, filled the cozy little room.

At this point Fluttershy was done playing with the cum on her face and decided to spectate the two. An idea popped into her head. She found the potion bag and pulled out another pleasure potion. Syn noticed her and quickly uncovered her devious, yet brilliant, scheme. Fluttershy struggled to pull the cork out, but when she did, she poured some onto Syn's dick. Then, she poured some of it onto Celestia's ass and watched as the liquid flowed down her voluptuous ass and into the crevice. Fluttershy made sure that every bit was covered in the stuff.

Syn grunted heavily, "thank you, Fluttershy." Fluttershy simply giggled and nodded in response. She took a step back to give them some room, but quickly sat down and started masturbating. All the while Celestia was moaning and groaning almost animalistically. Her lust for Syn and her need to cum grew stronger with every thrust. She looked back at him, her eyes pleading and begging for more. This time, Syn decided he would take his time, let her need build up. Tease her into submission, in a sense. He didn't speed up but instead thrust deeper into her. He'd sometimes pause for a brief second while completely inside, sometimes he'd pause while only the tip was in. It drove Celestia mad.

"Oh, please, Syn, just rut me already!" she barked. At this point he figured she'd had enough torture and gave her what she desired. He vehemently had his way with her. No holding back. He rapidly forced himself in and out of her. Her pleasure spiked through the roof. She moaned, screamed, and twitched madly. Quickly, she came, however Syn didn't stop. He wasn't done with her yet. Her pussy clenched and squeezed his never stopping member.

"I'm not stopping until I am satisfied," Syn said under his breath. He kept his promise, continuing to fuck her senseless until he finished. Celestia came several times, each orgasm more powerful than the last. Her pussy now swollen, red, and somehow, more wet than ever. She couldn't form any kind of coherent thought. She could barely even breathe because of her constant moaning. Eventually, Syn came inside her. His cum filled her completely and then some, spilling out and stained the fabric beneath them. Celestia fell forward and tried her hardest to relax after that ordeal. An amazing ordeal no doubt, but an ordeal nonetheless. Syn fell backward and took a deep, satisfied breath. Fluttershy crawled over and cleaned up his cum stained pleasure rod. Syn chuckled and looked over at Celestia's convulsing body.

"Hey, do you think she'll be alright?" Syn asked Fluttershy.

"She's a goddess, I think she'll be okay," Fluttershy replied with a sly grin as she licked his tip. Content with that answer, he laid back, closed his eyes, and relaxed.

"So, would you say that was a success, Fluttershy?"

"Yes, I think so," she replied with a cute giggle. Eventually Celestia was able to regain her composure and stood up. She slowly trotted over to the notes that were on the floor. However, they apparently became covered in cum amidst the fun they were having. She tried to make out as many words as she could, but it was pointless, the paper was destroyed. Though that wasn't necessarily an issue--she could write them down later. For now, she went back to Syn and laid down beside him. Fluttershy then moved to the opposite side. The two of them held Syn close.

"So, how was it, princess?" Syn whispered.

"Delightful," Celestia whispered back. Syn turned his head toward Fluttershy.

"And you?"

"Perfect," Fluttershy said as she closed her eyes and happily sighed.

"When are we going back to the castle?" Syn asked.

"Hmm, never," Celestia giggled, then said, "after a good nap. Your performance really drained me." Syn nodded, feeling quite tired himself. The trio fell asleep. The sun was still high in the sky.
