The next morning, Tempest got out of bed. Her suit had been left for her, but she didn't bother to get dressed unless they were going out that day.

She walked out onto the indoor balcony, yawning. Her member was erect with morning wood but she didn't notice. She'd gotten used to it. The muscular goddess went down the stairs. She put on an apron and began cooking. Twilight tended to eat pre-packaged food. Tempest didn't like to let her eat nonfresh food if they weren't traveling.

Twilight came down the stairs soon after. She leaned on the opposite side of the cooking island, looking at the eggs in the pan. "Morning."

"Ngh," Tempest said.

"Yeah. Neither of us are morning people." Twilight yawned.

As Tempest moved across the kitchen, Twilight saw her morning wood. And the dark stains on the apron. She smiled a little. It was amazing her body could still arouse her like this after basically becoming a nudist. She felt moisture running down her legs. No matter what hazards this island held, no matter what it was doing to them… by Celestia, was it fun. Twilight hadn't really been a sexual being before coming here, besides some fooling around, but that had completely changed. She looked down at herself. Her new body was practically made for sex, an attractive and sleek but not a bimbo form. Just like the queens themselves, the height of lust and attractiveness.

She gave a glance at Tempest. Her enormous bulk was a perfect blend of a perfect athletic frame and a gorgeous fashion model, with muscles complemented by a hefty amount of fat. She had a barely visible six-pack, thick girthy muscles layered with skin, and in particular, her rack that Twilight had to avoid staring at. Yet as she moved around the kitchen Twilight's drooling continued as she observed her marefriend's muscles working, lifting a heavy cast iron pan like a paperweight. Twilight wanted to see those muscles crush something. Maybe my head…

"Food is ready," Tempest said, dumping the pans into the sink and getting a pair of plates.

Twilight stepped over, "And I can think of something to have for dessert. Maybe to wake us up?" She gripped her member through the apron and grinned.

Tempest grinned back at her and leaned down to kiss her. Twilight felt herself becoming wet.
"Good day. I'm glad to have found you," a voice said. Twilight and Tempest covered themselves. Behind them, in the open living room, sat another pony, lounging on the couch. She was a tall blue mare in an evening dress.

"Queen Luna!" Twilight exclaimed.

Luna didn't bat an eye at their nudity. "I see you've been enjoying yourselves." She stood and walked over to the pair, looking them up and down. "I'm surprised to see either of you at my eye level. The magic still remains, then. I'm sorry I didn't get here sooner." She wore a sleek dress with a gap open on one side, with an asymmetric neckline. Her lovely navy blue hair spilled down past her bare pale light blue shoulders. It traversed down to the small of her back, and she shook her head, making it shiver. She was as tall as Tempest was and had her figure. While Twilight followed more of Celestia's physique, almost a jack of all traits, Luna was focused on martial prowess. She filled out the dress perfectly with the same sort of curves, though she was better at pulling off a dress than Tempest was. She was wider at the waist, with a pair of thighs to match, yet still had a substantial amount of cleavage. Her arms were slender, yet every time she flexed revealed she was almost as strong, and just as muscular as her sister.

"P...pu...princess Luna," Twilight stammered.

"Your Highness…" Tempest gaped.

“Yes, it is me,” She said kindly, “I'm glad you are both okay.”

The princess stood up and walked forward. She stepped between them and passed into the kitchen. Both mares checked out her ass before Twilight shook her head, "You found us! But…What are you doing here? How did you find us?”

"It seems records of this place were lost," Luna said, as she slid a mug into the kitchen water dispenser. "I must confess even I forgot about it. I couldn't find you until I saw this place in your dreams and the storm. I came to rescue you."

"Is the crew okay? What happened to them?" Twilight asked.

Luna nodded, "All collected and accounted for. It was you who has been missing the longest." She looked around, "And now I know why."

"Great. and the others?" Tempest asked.

"All fine. We have been trying to find you since you disappeared."

"Well…that is good…" Twilight cleared her throat. She looked around for anything other than her arms she could use to cover up. Luna paused and raised an eyebrow. Seeing Luna's outfit had both mares… excited. They tried to focus. Her eyes flicked between them. She sipped her drink. Twilight immediately smelled something familiar. "Are you...drinking one of our… ahem, milkshakes?"

"Why, yes," Luna replied, then smiled in a playful and almost threatening way. "I'm fairly certain there's only, ahem," she imitated the sound, "milk in this one, anyway."

"How do you know about that?" Tempest demanded.

"You're not the first ponies to be here,” Luna said with a sly expression.

"So then you know what this place is?" Twilight asked. "What is it? Where are we?"

Luna sighed. "This is Betrothal Island."

Tempest coughed. Twilight blinked, "I'm sorry?"

"It's an ancient land used for alicorn relationships and vacations,” Luna said easily, sipping her drink again.

"So, what is it?" Twilight asked.

Luna nodded patiently, "It is a land for alicorns, their guests, their families, and some forms of nobility once upon a time. It is protected by a powerful magic storm. Only authorized beings can pass through it. I never imagined that you would stumble on it, much less be stranded here. But then again, it's been some time since an alicorn or any of their families have used this place." She eyed Twilight meaningfully.

Tempest nodded, "Is this why none of the crew landed here? Only us?"

"That is correct."

"Because of me?" Twilight wondered, then shook her head, "Wait, but this still doesn't explain…" She gestured at herself and Tempest, "Everything! Our transformations, our behavior… What is Betrothal Island?"

Luna nodded. "No doubt you have detected the magic influence here?”

“Yeah, it's been driving us nuts,” Tempest said. She respected the royals, but her time abroad had changed her attitude. She didn't care for those who kept secrets.

“It is an island paradise, created by the princess of love before Cadence, and it was derived from a sample of chaos magic. We never learned where the princess got it, only that it was.” Luna gestured at the pair, “It appears it was never properly deactivated."

The pair looked at themselves, then at each other. "I see," Twilight said. "What does it do?"

"What is it for? Jerking off?" Tempest demanded sardonically, folding her arms.

"It's an island made for... compatibility,” Luna said slowly, “One might say it is a honeymoon location, but several couples came here beforehand. It adopts the fantasies of the users, integrating them with one another in compatible ways by transforming them." She gestured to them, "as you can see."

"So you have an island that...that transforms people like this?" Tempest gestured at herself, "Do you have any idea how dangerous this is?!"

"Do you have any idea what this does to us emotionally?" Twilight demanded. Had they been forced into love? It all added up. This was some sort of trap--

Luna put up a hand. "Please, do not panic. I'm as shocked as you are..." she smirked a little, "But not for the reasons you think. It is not radioactive. It only works with lovers."

"What?"

"Or those who have a mutual attraction," Luna amended, "It does not affect purely platonic relationships."

The two lovers before her looked at each other. "But we…we can barely keep our hands off each other!" Twilight exclaimed.

"And by Celestia, I've never felt this worked up in my life!" Tempest added.

"The spells don't affect consent. It acts as an aphrodisiac but it's not mind control. It hasn't impaired you from doing other activities, has it?" Luna asked.
"Well no..."
"Then I think you two just really like sex.” The queen said bluntly. Tempest looked away. Twilight's face burned red. At their flustered looks, she sighed, “I suggest you two find out what it is that is between you." Luna sipped her milkshake. "The island brings couples together. It is obvious you two care a great deal about one another. Now that you know the true nature of this place, perhaps you should have a discussion.”

Twilight and Tempest sat down, on opposite sides of the seating area. Twilight grabbed a pillow and put it over herself. Tempest crossed her legs and leaned back. "So...we couldn't keep our hands off each other?" Twilight asked.

"We couldn't stand to be even a few minutes apart," Tempest said.

"We were holding hands every chance we got!"

"That sounds like physical symptoms of love to me." Luna smiled as she took a seat, "Or at the very least, intense lust by some of the most powerful magic users we know."

Both mares flushed and avoided eye contact. Twilight looked down. Her jiggling breasts made a thought occur. "So…you said you were sorry you didn't get here sooner. Does that mean... this is permanent? Our bodies?"

Luna grimaced sympathetically. She set down her drink. "I'm afraid so. The island is hazardous for a reason, after all. It is why it was quarantined. And that is part of why the storm exists. The chaos spells are powerful. We can do research, but it will take time. It would be easier if we found you earlier but you've already been… recast.”

“Recast? Was that the semen bath?” Tempest asked.

Luna gave no surprise at the bluntness. If anything she was amused. “It sometimes takes that form. You were altered before you were submerged, but the recasting process reconstructs your frames. These are your bodies now, your DNA has been completely reconstructed. For all intents and purposes, as far as you are concerned, you were born this way."

The altered Twilight and Tempest looked at each other. At Twilight's busty body and Tempest's ripped frame.
Tempest's new body was seven feet tall. She had powerful and distinct muscles, every time she flexed something massive would move. Her breasts were huge, nearly the size of her head. Her skin was pulled taught over her muscles, showing off her abs, her hips, her waist, and her other curves. It accentuated her buttocks. Her face was as beautiful as the day they'd met, but her mohawk was even taller, looking almost like fire in its glory. Her shoulders were broad, and her thighs were wide. And between her thighs was a powerful member. She was ripped like an amazonian goddess.

The new Twilight was a sex goddess of a different breed. She was only six feet. Her muscles were different, more oriented to sex appeal in some ways. Her breasts were enormous, twice the size of Tempest's. Her hips were drawn into an hourglass shape with a wide waist above an enormous bubble butt. She was incredibly curvy, her belly stood out attractively from her torso, with a distinct belly button. Her shoulders were slender, but still carried a proud frame of respect. Her thighs were less dense than Tempest's. As sexy as her body was, it complimented Tempest quite well, as she did her. Luna watched them eyeing each other up. She smiled knowingly and went to refill her drink.

"So. You're a sub," Tempest said.

"How can I be anything else with that thing looking at me?" Twilight demanded, and gestured, "Obviously this thing is lowering our inhibitions..."

"Is the aphrodisiac affecting us?" Tempest snapped at Luna, as she returned from the kitchen.

"Why can't we stop...you know...?"

"Certainly it is affecting you, but..." Luna grinned mischievously, "Again, I think you two just really like sex."
"That can't be it!" Twilight exclaimed, "We've been..."

"I've seen your dreams, Twilight,” Luna said dryly.

"...it's not like I remember them that often!"

"I am simply describing what I am seeing." Luna frowned, seeing Twilight's face. "If you want to know the truth, simply speak to one another!" She gestured to both of them. "Put some clothes on if it helps! Just know that this is the best option! You will like it better this way, to put everything out in the open.’

The naked amazonians flushed, looking at the ground, the ceiling, anything but each other. Then Tempest shot to her feet. Rigidly she walked across the way. Twilight screwed up her face and did the same. They met in the center, glaring at each other.

"I didn't take advantage of you!" Tempest said immediately.

"I didn't say that, it was a magic spell," Twilight hissed.

"Yeah, and I wasn't lying at the start!"

"Implying you were lying in the middle?"

"Do you love me?"

"Do you love me? Is any of this real?" Twilight demanded.

Suddenly Tempest grabbed Twilight, dipped her low, and kissed her. "Did that feel real?"

"More or less." Twilight kissed her back, "Did that?"

"Maybe. I think I need to check." They made out for a long time. Luna tilted her head as she watched Tempest's member grow conspicuously larger by the second.

They finally broke and looked down at themselves. "So...now that that's sorted…" Luna commented, “Again, you weren't being controlled. You two just really enjoy sex, and really enjoy loving each other.”

Tempest held Twilight in her arms. "So, for now, we just stay like this?" She asked.

“I am afraid so. However…” Luna shrugged, "I've never regretted my time here. There are certain bonuses one can appreciate." She gestured, "We cannot get pregnant unless we wish, for instance. And we are exceptionally strong."

Twilight blinked. "Luna? You…"

Luna stood up. Then she reached back and unzipped her dress. Tempest couldn't cover her erection anymore as the queen of the night performed an impromptu striptease. She opened the top of her dress, revealing breasts even larger than Twilight's, though still smaller than Celestia. She then pulled open her dress, revealing nothing underneath. A massive cock sprang out, only a bit longer than Tempest's. Yet she also still had a vagina underneath. "You were here too?" Tempest breathed.

Luna nodded, turning in place, letting her dress drop as she revealed an attractive rear. "My lover...moved on, but she still lives in my heart..." She glanced down, "...And my body. She was once the princess of friendship before you, Twilight."
Tempest felt a splatter of liquid on her feet. She looked down to see Twilight drooling, and her pussy so wet it dripped onto her feet. Twilight looked up at her, "I...no! I love you! Princess Luna, what are you doing--?"

"I've seen both of your dreams," Luna said mischievously. She folded her arms. “When in Canterlot…”

“Do you have to do as they do?” Tempest grunted.

Luna tilted her head at Tempest, then folded her arms, and cocked her hip, putting on a little display. Tempest flushed. Her breath quickened. Then she looked at her lover. Luna smiled, “You two are so… adorable.” She walked closer, and both mares were rooted to the ground. Then she gave them each a kiss on the cheek. “I shall make breakfast for myself then, shall I?” With that, the Queen of the Night turned and walked toward the kitchen. She checked the cabinets and the fridge as if she owned the place, then put on an apron, hiding most of her delectable body from view.

Twilight sat down at the table and cleared her throat. “So you can take us home?”

“Oh, easily,” Luna said, “But I thought you would want some time to adjust.”

She quickly whipped them up some eggs, and then, much to Twilight's surprise, a sausage that she put on Tempest's plate. She put the plates in front of each of them. With a glance at Luna's cleavage, Tempest quickly dug into the sausage. “You eat meat?”

“Yeah,” Tempest swallowed, “You get weird habits in the Storm King's lands.”

Twilight shuddered, then dug into her food. She tries not to ogle her marefriend's breasts and really had to resist Luna's jiggling bust when she sat down as well. This did not go unnoticed. “I'll send a message to Canterlot immediately, telling them I found you,” Luna said. She paused, “Shall I announce your engagement?”

Twilight choked on her drink. “What? No…”

“It is Betrothal Island,” Luna pointed out, then smirked knowingly, “And you two are quite close.”

“No, I mean, she's my friend–” Twilight stammered, “I mean she's my marefriend now, but–”

“We don't want to put on any labels or anything just yet, is what she means,” Tempest said cooly.

“Very well.” They finished their food in silence. Soon, Luna stood up, “If you'll excuse me, I will enjoy some of the island's other amenities.”

Tempest eyed her up and down. “Dressed like that? Or not at all, rather?”

“It's been some time since I've had a vacation.” Luna smiled. She raised her arms in a stretch, jutting out her chest, and grinned as Tempest reddened and folded her legs together. “And it is Betrothal Island, Commander, we tend to be a bit natural.” With that, she departed. Twilight and Tempest watched her go, seeing her bouncing buttocks.

“So, what do you think?” Tempest murmured.

“Rescued at last?” Twilight asked, her head snapped back.

“Well, yeah,” Tempest hissed, “I mean…” She controlled her voice, and her hand slid closer to Twilight's.

Twilight drew her hand back. “I… I don't know. It's all so much, so fast…”

“We've been doing well so far…”

“We didn't plan on…!”

Tempest blinked, “Wait, I mean being your marefriend.”

“Oh… I thought you meant engagement.” Twilight turned away, quite red.

“Oh, you always do that…” Tempest snorted.

“Says the one who can't ever close the windows…” Twilight turned her head back.

“Say that to my face.”

Twilight stood up and kissed her. “We're rescued.”

“I know.”

Luna stood around the corner. She smirked. She had to send another letter, but that could wait until these two figured it out.

XXXXX

About an hour later, Luna climbed the stairs to the library. All the old titles had been updated. But she wasn’t exactly interested in that. She sat down on a large bean bag. It tickled against her bare skin. Thankfully, the building was air-conditioned. There was no sweat to worry about. She grasped her cock. In an instant, her massive blue member rose to full hardness. She began to stroke it, slowly, then forced herself to relax.

“Oh, Autumn, how I miss you…” She purred to herself. The gray mare in her memory, gone long ago, had Twilight’s massive rack, and her smooth skin. Luna could hear footsteps in the distance but didn’t care. “Mmm…” She purred. Her member felt so strange. If she pushed it down, it got more excited. She smiled.

“Ah, your highness!” Luna opened one eye to see Twilight standing there, seeing the monarch with her hand around her dick. “Do… I know you said you wanted… do you have to…?”

"It's not as if I brought any clothing," Luna smirked. She ran her hands up and down her body, as if by accident. As always, the lesbian’s libido couldn't take it. "I think I deserve a bit of a vacation as well, don't you?” She winced and touched her cock again. Then she came. A hail of cum shot out of her, striking Twilight in the front. The mare cried out and staggered back as she was hit by two more blasts. It wasn't random. It was all aimed at completely covering her body. Luna smirked. She hit Twilight's crotch, her legs, and her feet, then her chest again for good measure.

Twilight stammered as she tried to wipe her eyes clear. Luna was up and standing in front of her, massaging her stallionhood. Twilight looked down at herself, covered in white cum. “You really do look a lot like her, Twilight. Only your patterns of colors are different.” Luna smirked. “And I think this island has shown your habits are like hers as well.”

Maybe it was true, maybe it was dirty talk. Twilight slid to her knees and moved forward on them. Luna slid against the wall and relaxed a bit. “With your permission, Your Highness?” Twilight asked cautiously.

“Granted.” Twilight took in Luna's massive marehood with one hand. It was huge, and musky, and her testes pulsated with fuel. Luna ran her hand through the princess’ hair. Twilight licked her lips. Luna leaned back in anticipation. Twilight leaned forward and ran her tongue along the side. Luna gasped and her hips bucked against the stimulation. She splayed a hand out, while the other reached Twilight's head.

She felt Twilight smirk. The scholar hefted Luna's balls with one hand and lifted her shaft with the other. It felt like a curtain rod. She summoned her courage and bent her head over Luna's long penis. It slid into her mouth like a sausage slathered in butter. Her jaw opened unnaturally wide. Twilight's eyes widened and she felt no resistance. It was warm, very warm, and she felt her tongue rise up to tease it. Then it hit her throat. Her mouth tightened and she felt both of Luna's hands on her head.

The queen gasped. Twilight's throat was like a vice. She pushed the mare down. Her cock slid into her and was squeezed tight, sucking and churning. “Oh… it's been too long.” Luna felt the other alicorn's mouth, felt her sliding past into her throat.

“Mmf,” Twilight grunted.

Luna gritted her teeth, “Oh, I'm sorry, Twilight, but it has simply been too long!” She shifted them over onto the futon. At the same time, Twilight detected the tingle of magic. And something long and hard slammed into her vagina. She tried to lift off, only for two strong blue hands to pull her head back. “I want my lovers to experience all the delights…” Twilight felt two more smooth clasps wrap around her ankles and pin her legs to the ground. Another appeared to restrain her wrists to the futon. She found she had a limited range of motion to reach Luna’s hips. “...and that includes certain kinds of restraints,” Luna finished devilishly.

Twilight screamed out in pure happiness. She hadn't tried this kink before but damn if she wasn't into it. Luna lifted her head and looked down. Twilight was pinned by magical blue chains to her. Luna held her in place but allowed her to rise up slightly for air. Then she began to thrust. Twilight squealed out in ecstasy. Twilight's throat widened and stretched, then tightened and contorted. Luna smiled as she felt Twilight's throat molding to adapt to her new lover's body. At the same time, a magic blue phallus pushed into her lower lips. She squeezed her eyes shut as her innards pulled it in. Relentlessly the object pushed inside her, not quite thrusting, just a relentless drill. It finally stopped at the end of her chasm. It suddenly expanded, like a gas before solidifying. Twilight's eyes popped wide. It filled her out entirely, every nook and cranny of her insides. Then it pulled.

Twilight's mouth opened and closed around Luna's penis. The dildo pushed in again. “Oh, it's a unique spell, Twilight,” Luna muttered, “It adapts to your insides. I’m– ngh!-- using it myself!”

Twilight screamed out. The magical dildo had all the right curves, all the right ridges, and all the right points that would stimulate her. A dildo made exactly to her specifications.

Twilight's attention went forward. She stuck her fingers into Luna's vag and felt a magic barrier there. Two could play at that game! Twilight powered up her horn, haltingly and sporadic. A purple beam smashed into Luna's, and now Luna was on the back foot.

Then her cock swelled. Twilight’s throat bulged out and she heard what sounded like rushing water. Her mouth was filled with a delicious white liquid. It forced itself down her throat, bolts of goo. They stuck to the walls of her body as she was forced to swallow. It was like drinking honey at ten times the speed. It stuck to the perimeter of her throat, her esophagus, and then her belly. “Mmph!” She screamed as she felt her insides being filled up with white hot cum. She felt intense heat fill her stomach, a gooey and weighty mass that turned her tummy into a storage vessel. “Ugh…” She moaned out around the cock. She felt it with her hand. Her abdomen was filled out with cum. It expanded until it went taut.

The rushing sound tapered off. Luna looked down at her and smiled, “Don't worry. You wouldn't pop.”

Twilight's mind was completely overwhelmed, barely registering the volume of cum depleting. She slumped forward. Luna let the restraints vanish into the magical ether. She tenderly lifted Twilight’s head off her member. The mare’s eyes cracked open wearily. “That…”

“My word…” Luna smiled, “Get some rest, my friend.” She gently pulled her onto the futon, letting Twilight collapse while her body digested the influx of cum. “Now, to see to someone else…”

XXXXX

She went back downstairs. Tempest was cleaning up from breakfast and had apparently not heard their little session.
She made a lunge. In a flash, Tempest side-stepped her and pushed her against the counter. Luna’s outstretched hands were pinned to the counter by her wrists.

Tempest’s grinning face appeared in her peripheral vision. “Twilight might be one submissive gal, but I’m not quite the same. You gotta buy me dinner at least if you want that.”

Luna smirked back, “Well then. You seem to have me caught.” She ground her rump back against Tempest. She felt the mare’s erection. “How are you enjoying your new body, Commander?”

Tempest ground her hips against Luna, then straightened up, “Stay put.” She stepped out in front of the counter island. Her moderate breasts jiggled slightly. Her muscles glistened in the light. “I’m enjoying it fine. The muscles are great. Twilight certainly appreciates them.” Luna bit her lip to show she enjoyed it the same.

“I can do the same.” Tempest yanked out duct tape and put a strip over each of Luna’s hands on the counter.

The queen found herself unable to move. She sneered, “As if that could hold me.”

“Oh yes,” Tempest replied, “If you didn’t want this, you wouldn’t have come up to me and given me this opportunity.” Tempest’s face became sinister. “You know… I think you need to pay.” She yanked Luna’s hair back. She tied it into a ponytail. Then she used her hands to explore Luna’s body. She ran her hands along Luna’s arms, then forward to play with her boobs. Tempest grinned. She bounced the hefty orbs in her grip. Round, squishy, and unusually big. “I bet you get mares looking at these all the time.” As if it was somehow possible, Luna could feel Tempest’s erection getting harder. The mare used her thumbs to play with her nipples. Luna bit back a moan. She was so hard herself. Her eyes went wide as one of Tempest’s hands slid lower. While she kept playing with the Mountains of Equestria, the other went for the valley. Luna could feel herself quivering as Tempest’s large hands ran down her smooth stomach… then reached her cock. “I might have fun with this.”

Luna’s breath hitched as she felt Tempest pull her hips back. She felt the head of the dickmare’s dick against her anal cavity. Tempest thrust. “Ooh!”

Tempest made a strangled noise, then gasped out, “You alicorns… so ready, aren’t you?”

She slid in with such ease. Alicorns just seemed made for sex. Even Luna wondered about this. Why were they so easy? Her brain short-circuited as Tempest began to plow her. She was completely immobilized. Tempest trapped her legs between her powerful thighs and drove into her like a pile driver. Luna winced and hunched over. She found her penis descend into a pitcher set beneath her. That’s the other question. Why are we so delicious? Her thoughts were shattered by Tempest’s train barreling into the station. She cried out and clenched her ass. She felt the massive member thrust inside her. “Aah!”

“Come on, impress me,” Tempest growled, “After this, I’ll get your sister…!”

Luna, somewhat dizzy, timed a thrust right back into the new dickmare’s body at that precise moment. Tempest yelled and was forced back in time. They battled back and forth, thrusting and diving in and out of each other. They hammered and ford through one another, clenching as they desperately fought to fight for one another’s climax.

A rush of force. Luna’s eyes went wide. The churning of testes. She braced herself. An eruption bigger than a volcano came from her crotch as she leaned back and fought to control her own organ. Tempest’s eyes went wide and she failed to pay attention. She hilted inside Luna just as her own dam burst.

Great squirts of cum sprayed in blasts as thick as a firehose, filling up Luna’s ass. The queen could feel her insides stretching; they’d hold, they were made for it. She was more surprised at how much and how full she felt. There was enough cum to fill an army. After such a short time on this island, how did she have so much? Luna looked down. Her lower body seemed to fill up, but not to the extent Twilight did. Being a natural-born alicorn created different tolerances.
As Tempest collapsed behind her, Luna ripped her hands out of the restraints and caught her, lowering her to a chair. “So. How was that?”

Tempest gave a weary thumbs up.

XXXXX

It was dinner before all three had sufficiently recovered. “So, after the weekend, we will all return to the mainland,” Luna said. “Is that sufficient? I’ve sent the message already that you are safe.”

“Excellent!” Twilight said.

“So what should we do until then?” Tempest asked.

Luna cleared her plate and wiped her face with a napkin before speaking. “I think… Twilight needs some extra protein with her meal.” She locked eyes with Tempest, and the amazonian mare returned her gaze with a predator grin.

Luna stood up. So did Tempest. Before Twilight could blink, both mares were beside her and helping her up. “O-oh! B-both of you?”

Tempest brushed Twilight's feet out from under her. As she fell, Tempest caught her by the arm, and bent her knees, pushing her onto all fours. "Tempest, what--?" Tempest didn't answer and instead pushed her cock right into Twilight's vagina. Twilight yelped aloud. "Ah!"

Luna took the opportunity to move around and thrust into her mouth. "Oh, I missed this...you're perfect, Twilight!"

Twilight moaned aloud. "That she is," Tempest panted. She grabbed Twilight's wrists and pulled her arms behind her.
Luna wrapped up Twilight’s hair into a bundle and pulled it and her head back. “Mmph! Mmm!” Twilight cried in a shrill tone.

Tempest hammered into her hips, driving her onto Luna. Luna's eyes rolled up into her head. The trio frog marched back so she could lean against a chair. “My word, I would never have anticipated this!”

Twilight squeezed her eyes shut. She was in heaven. She was the perfect shape for both of them. Her body had been reshaped as a sex goddess after all. They established an equilibrium, thrusting back and forth as Twilight moaned out.
She was in heaven. She could feel all of Luna's indentations, and Tempest's cock was as perfect as ever. Her throat shifted rapidly to adapt to the new projectile slamming down her gullet. Sloppy sounds filled the chamber. Twilight's breasts lurched back and forth. She was leaning on all fours but strung out between her lovers, theirs to do with as they pleased.

She felt them swelling, felt them shudder. “Twilight…” Tempest murmured.

“Oh, yes…!” Luna said loudly.

Twilight's eyes went wide then rolled back in her head. Cum exploded into her body. It filled her esophagus and flooded her stomach. She felt her stomach begin to inflate. At the same instant, so did her womb. Cum rushed into her vagina at an enormous rate, a dam swelling and bursting into her body and filling her like a balloon. The pleasure was so intense and it just wouldn't stop.

It wasn't like the previous times, there was cum this time. Luna screamed. Tempest roared. And Twilight moaned. She was filling up, her entire body crammed full of enough baby batter to impregnate a village. And she kept orgasming herself. It just kept coming, flooding, splashing, filling. Then all at once, Tempest slipped back. She fell on her ass and let off three volleys of cum before finally tapering off. One splattered Luna's upper body. The second hit Twilight's head and her lower body. The force was so shocking and intense that it threw Twilight forward. Luna's surprised cries of passion filled the room as she orgasmed with her vagina, then sent off another final shot of cum. It blew Twilight off her member and onto Tempest. The commander caught her marefriend as she fell, seizing her in her strong embrace. Both were painted white. Twilight smiled with joy. She lay back into Tempest's massive, bulky, and broad form. She leaned back, her body form-fitting to Tempest's full frame. Luna leaned against a chair, panting heavily. “That was amazing,” She said finally.

“You still have your snatch,” Tempest observed.

“That I do,” Luna said. “I'm afraid that to return yours…”

“Forget about it for now,” Twilight said. She climbed out of Tempest's grasp. The trio went to the front room. Twilight directed Luna to sit on a couch.

Both purple mares had their eyes fixed on Luna's crotch. Twilight went closer. Luna was slightly taller than her but did not have Twilight's physique. She had smaller breasts and a more athletic body. “You're our guest, we should pleasure you.”
“Oh, Twilight–” Twilight kissed her. She stuck her tongue into Luna's mouth, dragging cum with her. As she did so, she straddled Luna’s legs. With one hand, she worked up the queen’s stallionhood.

Twilight hovered over Luna, then let herself drop. She and Luna cried out. She was perfectly tight. She felt herself and Luna's member churning as the magic fought to accommodate themselves. They were almost frozen, and she felt Tempest's arms lift her up, then back down.

Luna tilted her head back. Her eyes went wide just as Tempest thrust herself deep into her throat. She grinned at Twilight, "Mm, so this is what other alicorns are like..." She squeezed Luna's breasts. "A pity you don't lactate like Twilight does." Luna's horn glowed. Her breasts squirted a jet of milk and Tempest smirked with satisfaction.

The sensation of all three of them tied together was too much. Luna ejaculated liters of cum into Twilight. She screamed into Tempest's mouth as her belly inflated, and Tempest pulled her closer. She threw her head back and thrust once more into Luna, driving spurt after spurt of lusty cum into her belly.

Twilight was positively filled. She and Luna both had enormous bellies, but Twilight looked nine months pregnant. They lay together in a pile.

“So, we go home on Monday?” Tempest asked.
