As the cruise continued on its present course, the sun had slowly risen from the edge of the ocean. The sun soon light throughout the entire ship.

Within one of the cabins, was Starlight, Anon, and Princess Twilight. The two ponies turned humans arrived to warn Anon about the pills he gave the girls, but it was too late as each and every one of them got laid with him. During some, ahem, ‘research’, they discovered how the girls transformed, and the aftermath that came from it. However, during that time, it happened to the Equestrians turned humans as well. But instead of resisting, he allowed it. Starlight was quite something. But when Princess Twilight sort of cornered him, Anon confessed to her, which in turn, made her return the compassion.

The morning sun rose, causing Starlight to stir as she slowly got up. But as she sat, she failed to notice that part of the blanket fell off, and felt a sudden chill.

“Whoa,” muttered Starlight, “Why am I suddenly feeling…?”

She got her answer as she noticed that she wasn’t wearing any clothes, making her blush madly at this. She covered it with the blanket and looked in a state of panic.

‘What in Equestria just happened?!’ thought Starlight.

However, she looked to her left, and to her shock, both Anon and Princess Twilight were also naked. Not only that, but they were snuggling one another too.

“Twilight?!” said Starlight in shock.

Princess Twilight squirmed and slowly sat up and rubbed her head.

“Boy, what a night.” Said Princess Twilight, “And why do my legs feel somewhat funny and I feel wet?”

“I think we know.” Said Anon as he also sat up.

Princess Twilight looked at Anon, then blushed with a smile. “Guess that explains everything.”

“Though I’m surprised you can still remember everything after all that.” Said Anon.

“Let’s just say after the potion Celestia had us drank from what happened between you and Smolder, I had to come up with a few spells to help retain my thoughts and try to be me.” Said Princess Twilight.

“Clever.”

“Can we talk about what happened last night?!” said Starlight in a panic.

“You took the pills by mistake and ended up transforming too.” Said Anon. “Though to be fair, having them disguised as mento tablets wasn’t such a hot idea.”

Starlight looked at where the pills were, and realized her mistake. She slapped her forehead and groaned, “Oh, come on.”

“Don’t tell me you didn’t enjoy it.” Said Princess Twilight, which shocked Starlight as she looked at her with a gawking expression.

“Though what are the odds the others would be waking up as well?” asked Anon.

Suddenly, they heard loud screams, startling them at the same time. One by one, they could hear them.

“What in tarnation?!”

“What the hay happened?!”

“What is going on?!”

“Eep!!!”

“What just happened?!”

“What the heck?!”

“Oooh, I feel tingly!! And I’m freaking out too!!”

Anon and the two ponies turned humans slowly looked at one another.

“We should probably get dressed and tell them what happened.” Said Anon.

“Good idea.” Said the two of them, allowing them to get up to quickly get dressed.

******************************************************************************************************

After they got dressed, Anon, Twilight, and Starlight were standing near the door.

“We’ll wait for them here,” said Anon, “I asked them to bring room service breakfast to our floor, that way we’ll get something to eat at the same time.”

“Good call.” Said Starlight.

“But should we go out and…?” asked Princess Twilight before being cut off.

“Don’t worry,” said Anon, “They’ll be knocking right about…now.”

They heard frantic knocking in front of their door, surprising the ponies turned humans.

“Oh, you’re good.” Said Starlight before Anon shrugged.

He was about to open the door, but then he stopped. He turned to the ponies turned human and motioned them to step backwards, which they did. Anon then frantically opened the door, causing the Rainbooms to fall through the door. All of them frantically stood up and talked to Anon.

Some saying that they were in their rooms, they blacked out, then they woke up in their rooms all naked.

“Everybody calm down!!” said Anon as he was able to make them quiet. “First of all, we got guests.”

He motioned to the guests behind them, causing them to look, with the said latter waving at them.

“Princess Twilight? Starlight?” said the Rainbooms surprised.

“Hey, guys.” Said a nervous Starlight.

“What are y’all doin here?” asked Applejack.

“They came here to warn me.” Said Anon.

“Warn you?” said a confused Rainbow Dash.

“About what?” asked Pinkie Pie.

“Let’s just say…the pills didn’t exactly help you in the best way we thought it did.” Said a nervous Anon.

“Oh, please.” Said Rainbow as she shrugged her shoulders, “How bad could it be?”

******************************************************************************************************

The Rainbooms sat on the bed, their jaws dropped and their faces blushed madly by what they were seeing. For in each monitor, they were seeing were them, but older, and all of them having a wild time.

Fluttershy whimpered a bit, with Rarity saying, “I feel so…violated.”

“How?!” exclaimed Twilight.

“Whilst Anon was working on the chemicals, someone swapped one of his chemicals with the one we locked up.” Said Princess Twilight.

“What chemicals?” asked Rarity.

“See, a while back I was working on something new on the chemicals to see what I can make. But then one of my students, Smolder, drank it behind my back without noticing.” Said Anon. “Which she didn’t know, because she drank from a random jug.”

“Why not a chemistry set?” asked Pinkie Pie.

“Turns out Rainbow’s pony counterpart destroyed them for a prank back in Equestria.” Said Anon whilst Princess Twilight growled.

“That does sound something like Dash would do.” Said Applejack, which Rainbow face faulted, but didn’t deny it.

“And as a result,” said Anon as he pulled out two pictures. “She went from this…”

He showed them a picture of Smolder, which they had to admit, she looked cute.

“Aw, how cute.” Said Fluttershy.

“To this.”

The moment Anon showed them the picture, all of them had their jaws agape as they couldn’t believe what they were seeing. They saw Smolder’s body as a mature woman, as if she had gone straight up anthro.

“How the heck is that possible?!” said Sunset.

“Honestly, we have no idea.” Said Starlight.

“Nevertheless,” said Princess Twilight, “After we discovered from Princess Ember that the chemicals ended up speeding up her maturity, which in the end had him chosen as her mate.”

This caused the Rainbooms to blush at this.

“Trust me, I was completely baffled,” said Anon, “But because I didn’t lock my classroom, didn’t know she was in my classroom, and that she, well, was under the chemical’s influence, I had to take responsibility and help her out. Eventually I uh…did the deed thing.”

“Just say you had sex with her.” Said Rainbow.

“Rainbow Dash!!” said Rarity.

“Anyway,” said Anon, “After I helped her, she’s now back to normal.”

“But as for the leftover chemicals, we locked them all up to make sure nopony would ever take them.” Said Starlight, then giggled and said, “Or Anon.”

“What do you mean?” asked Twilight.

“See for yourself.” Said Princess Twilight when she handed them a list.

Anon was baffled, and asked, “Why the heck would you still have that?”

“What? It’s fascinating.” Said Princess Twilight.

As the Rainbooms looked it over, they were shocked when they read one of the ingredients.

“How the heck did you add your own pheromones?!” said the Rainbooms.

“Honestly, I have no idea.” Said Anon.

“But after Anon left,” said Princess Twilight, “We saw someone had broken into the vault and took the chemicals and swapped it with one of the ingredients with Anon’s pills.”

“So, when all of you took the pills, it turned you into well, what you see before you.” Said Starlight.

“And y’all didn’t know it was us?!” said Applejack to Anon.

“I didn’t know, I thought it was just a weird coincidence!!” said Anon, “Remember the Equestrian Magic that turned Sunset and Twilight into toddlers?!”

The Rainbooms, but mostly Sunset and Twilight, winced at that, for all of them remembered that one trip disaster when Equestrian Magic affected them.

“You know, he does have a point,” said Pinkie Pie, “I mean none of our friends recognized us when the two of them got turned into toddlers, or that time when we got turned into babies.”

“Though I’m surprised nobody recognized us because of our hair color.” Said Sunset, “I mean they’re a dead giveaway.”

“Despite your hair looking like bacon?” said Anon, which caused the said girl to glare at him with a growl, making Anon raise his hands in defense.

“You know, he does have a point.” Said Rainbow, which caused Sunset to face fault at that.

Anon then had a guilty look on his face before rubbing the back of his head.

“Listen, girls.” Said Anon as he rubbed the back of his head. “I’m sorry for what happened to you girls, it’s all my fault. If I had known…”

“Aw, it’s alright sugarcube.” Said Applejack.

“Yeah, you didn’t know someone tampered with your chemicals.” Said Rainbow Dash.

“And honestly, I think your pills did help us with somewhat of our problems.” Said Rarity.

“Really?” said the other three.

“Yeah, like Applejack’s seasickness, Rarity’s headaches and so on.” Said Pinkie Pie.

“Huh,” pondered Applejack, “Honestly ah feel great.”

The rest of the girls agreed to this. Though it didn’t turn out as Anon expected, he was at least happy that their medical trail was successful…er…in a way.

Suddenly a knock was heard from the door.

“Room service.”

“Oh yeah, I forgot about that.” Said Anon.

“You ordered room service?” asked Rarity.

“Yeah, I ordered extra for just in case.” Said Anon.

“Good call.” Said Twilight, “And given what we’ve been through, I’m sort of hungry.”

The others agreed and went over to the door.

“And uh, girls, one more thing.”

They looked at Anon and wondered what he wanted to ask. However, his face was red from embarrassment as he wanted to know something.

“Was I uh…good?”

This caused all of them to blush hard at that. But instead of protesting, memories of their night began to go through their heads, which in turn caused them to slowly smile and ended up giggling out of controllably.

“Oh, Anon, you were amazing.” Said Sunset.

“Once you took charge, you really don’t hold back.” Said Pinkie Pie.

“And how could I ever forget.” Mumbled Anon. Then he cleared his throat and said, “Let’s just eat something.”

“Agreed.” Said everyone as they made their way towards the door.

*******************************************************************************************************

For the next two weeks, Anon, Princess Twilight, Starlight, and the Rainbooms began to enjoy every part of the trip they were on.

Though Anon had gone through a lot of stuff because of the girls’ transformations, he was at least able to go to a few places with them.

He was able to go to the diner and ride the mechanical bull, but this time, each of the girls also had a turn. Though both Twilight and Princess Twilight…both of them had a lot of trouble doing that. They even fell off and looked like a mess, this caused them laugh out loud at that, with them laughing with them.

Next up, they went to the gym for a bit. Though some of the girls, namely Rarity and Fluttershy, Starlight and the two Twilights, didn’t want to go through the drills, the others did. Though Anon was competing with Rainbow Dash and Applejack a bit, as he didn’t want to show them that he was a complete slouch.

Then they decided to have some early lunch as all of them enjoyed. However, Anon was busy eating a bowl of chili. However, they suddenly saw him what he did yesterday.

“Tower to pilot, tower to pilot.” Said Anon to himself as he was messing around. “We’re tracking your approach. And opening our doors to some yummy goodness.”

Anon then directed the spoon to himself whilst he continued to act.

“Tower to pilot!! Mayday, mayday!! You’re coming in too low, pull up, pull up!! NOOOOOOO!!”

Suddenly Anon splattered the chili against his head. Then he deadpanned and groaned, “Why do I always keep doing that?”

This caused them to laugh extremely loud when they saw him make a fool of himself. Some of the guests noticed and they also laughed a bit.

Then they decided to do some laser tagging. Though this time, Anon was able to make sure that he and the girls were in the same team he is. Though Fluttershy didn’t want to do it at first, she suddenly remembered what she did when she was her other self, causing her to go crazy and take down many of her targets.

At the end, they won the tournament, with them having a group picture and showed the plaques that they won during those said contests.

They even hung out at the arcade as everyone had a great time. However, what was scary, was that Fluttershy was driving one of those racing games and she was acting like a complete psycho. Though it was great to see her having fun, it was greatly scary to see her. Though seeing that they don’t have any squirrel games, Sunset decided to challenge Fluttershy to a game. Both of them were equally tied and were evenly matched.

Then they went to a cake shop, where they get to enjoy the many different deserts that all of them enjoyed.

During that time, they decided to take the opportunity to explore the rest of the ship and all of them were able to join in watching a few concerts, as well as a few movies that all of them could enjoy. And thanks for the treasure that Anon brought in, all of them could enjoy the finer things in live.

However, two days before they went back home, the girls told Anon to come to his room, for they have a surprise of sorts for him. Curious, he wondered what that was.

Anon walked into his room and turned the lights on. To his surprise, he saw Princess Twilight, Starlight, and the Rainbooms waiting in his room and…wearing bathroom robes?

“Uh, girls?” asked a nervous Anon, “What’s going on?”

“Well, we figured that since our last night before the day we get back,” said Sunset, “We’d figure we’d have a night to remember.”

“Uh, like what?” asked Anon.

“The first phase.” Said Twilight before all of them dropped their robes, revealing them to be without clothes.

Anon blushed at this and wondered what this meant.

“The second.” Said Princess Twilight before all of them took out the pills. Pills Anon immediately recognized.

Anon widened his eyes in shock, realizing what they had in mind.

“Uh, girls.” Said Anon.

But it was too late. Each of the girls took the pills, and one by one, with each other’s help, all of them transformed back to their adult forms, which shocks Anon.

“Oh no,” said Anon, “Look, ladies.”

“Like we said, this is our last night.” Said Pinkie Pie in her adult voice.

This shocked Anon, and said, “Wait, you girls remember?”

“Of course,” said Princess Twilight, “Turns out if you take the pills the second time, you’ll still have your memories.”

“Whilst we’re in a more…alluring state, if you know what we mean.” Said Starlight.

“And we figured we might do this again,” said Rainbow Dash, “I mean you can’t deny that you’d want to do this again.”

Anon made a face, but nodded, for he can’t deny that.

Anon sighed, seeing that this is what they wanted. He undressed and used the stone to restore him to his normal age. The girls smiled at that.

“Now then, which one of us gets to go first.” Said Rarity.

“Actually, I already have a solution to that.” Said Anon.

He pulled out another stone, causing him to glow and made eight copies of himself, making it about nine Anon in total. This surprised the girls at the same time.

“I found this stone a while ago, and realized that it makes copies of us. I made more of these in case of an emergency.” Said Anon, “And given how all of you want to share…why not?”

Anon and his copies approached the girls as all of them were bear too.

“So, what do you say girls?” said Anon as he tried his best in a flirting tone.

“Ready to have some fun?” said Anon and his copies.

This caused the girls to get excited, causing all of them to lunge towards them, leading to an all-night fun session with all of them.

*******************************************************************************************************

A few days later, everyone was back on shore. But thankfully, it was still Summer vacation for them.

Once they docked, they went to the portal to Equestria, where all of them were saying their goodbyes.

“Thanks for inviting me to the cruise girls,” said Anon, “I can scratch this off my bucket list.”

“You’re welcome, Anon.” said Fluttershy.

“Yeah, even if what happened was something we didn’t have in mind.” Said Pinkie Pie.

This caused them to blush, but all of them had a good laugh about it.

“Still, sorry about what happened.” Said Anon.

“Aw, don’t fret there, Sugarcube.” Said Applejack.

“Yeah, you didn’t know it was going to happen.” Said Rainbow Dash.

“But you did pay for our entire trip, so we can let that slide.” Said Rarity.

“And the free goods we got out of it.” Said Sunset.

Anon nodded at that, then looked at Twilight.

“And Twilight?” said Anon, making said girl look at him, “I’ll also see what I can do to help lift that ban from you, so that you can work with chemicals again.”

This caused Twilight to get excited.

“However,” interrupted Anon, “No more crazy and wild science experiments. You want to make something revolutionary, you talk to me first, and follow my instructions to the letter.”

“Oh, don’t worry, I learned my lesson.” Said Twilight, “And thank you.”

Anon nodded, then looked at Princess Twilight and Starlight. “Alright then, it’s time for us to get moving.”

“Right, see you in a bit.” Said Starlight before moving through the portal first.

Princess Twilight was next.

“You girls gonna be alright?” asked Anon.

“We will,” said Sunset, “But we also have some summer jobs to get back to, so we’ll be busy till school starts again.”

“Alright then, I’ll talk to you later.”

Just before Anon walked through, he was suddenly hugged and kissed by the Rainbooms, surprising him.

“Thanks for a great day and night, Anon.” said the girls before they all went away.

Anon was stunned by this, then shook his head.

“I’ll never understand girls,” said Anon, “And that’s a good thing.”

He soon walked through the portal to Equestria.

*******************************************************************************************************

After they got back, Spike was there waiting for them. He greeted Anon, but was surprised that Princess Twilight and Starlight came through the portals first. Anon told him to tell the girls to get together, for this was going to be a long story.

After they arrived, the girls and Anon told them everything that had happened. Once they were done, Anon concluded, “And that’s what happened.”

The Mane 5 and Spike were shocked to hear this.

“Land sakes.” Said Applejack, “So that there formula that we locked up somehow got into yer pills?”

“It’s true.” Said Twilight, “Starlight and I discovered it after Anon left, so we went to warn him.”

“Though I’m not surprised about the rest of the girls’ transformations,” said Rainbow Dash, “I’m actually surprised that Fluttershy ended up having a split personality that made her more assertive and aggressive by a sneeze.”

“Don’t forget the changing of her mane and eye color.” Said Pinkie Pie.

“Though I must admit, darling.” Said Rarity, “I never figured that you and Starlight of all ponies would take it.”

“Well to be fair I made the mistake of making it look like ones of those Mentos candies instead of like actual pills, so that’s on me.” Said Anon. “Though there’s one thing that still puzzles me.”

“What’s that Anon?” asked Spike.

“Who the heck broke my formula out of the vault?”

Everypony looked at one another, wondering the same thing.

Unknown to them, someone was looking at them via magical mirror far away, whilst also having another mirror to watch…Canterlot High?!

She ate a piece of cake before setting it on a table near her sun flank. She gave an alluring giggle whilst her hoof was placed near her mouth as her mane flowed.

“That sure was a lot of fun.”

The pony picked up a checklist of sorts, which was none other than Princess Celestia.

“Now then…who to pick next?”

Author's Note

A quick heads up, this will have a bonus chapter, about a month after their trip. And there will be a surprise guest.
