They ended up naked.

. . .

When the light subdued, they all screamed.

"AAAAAHHH!" It was the only reaction from them, when they not only saw their friends, butt naked, but also that they themselves had no single fabric covering their naked bodies. Their hands immediately went to hide their body, putting one arm across their breasts, squeezing them to their bodies, while the second hand went to cover their pussies. Berry quickly realized her front was too big to cover with just her hand, so she curled up, hiding her breasts with knees pulled up to her chest.

"WHAT HAPPENED?! WHERE ARE OUR CLOTHES?!" Lily yelled at the bird, who was flying around them calmly.

"I was trying to explain it to you, but you were in such a rush. Your clothes got consumed during the transformation process, so you end up naked. I tried to…"

"Can't you transform us back? It's better than being naked!" Amelia argued, while also having quite a difficult time hiding both her breasts and pussy from her friend's eyes.

"You are out of energy completely, so it would be a waste to generate even a small thong for you." The bird flew onto Berry's head. "Although this one is quite exceptional. Maybe I could get half of your outfit back, if…"

"Why is Berry so special?" Amelia asked. "You said something familiar before, too."

"DOES IT REALLY MATTER RIGHT NOW?" Lily's was furious, even if by far she had the easiest job of hiding her boobs with one hand.

"It seems that one has the most sexual energy out of all of you, even if not by that huge margin. I can tell she didn't have any sexual intercourse, but I can say that she for sure she does the action of touching herself very often, hence the power.

"D-don't just say it like that!" Berry squealed, hiding her face between her knees, blushing.

"Touching herself?" Amelia asked with a clueless voice. "Like what?"

"I believe you humans use the word 'masturbation'", the bird explained.

"Mastur…bation? What's that?"

"You can't be serious…" Lily looked at Amelia, with her covered D cup breasts. Even though she couldn't see her nipples, she could easily see their plump shape. Her athletic figure - flat stomach and robust body, from all the exercise she was taking part in. Someone with such a desirable appearance, has no idea what masturbation is…

"Lily?" Amelia turned to her slim-shaped friend. "Do you know what he is talking about?

"N-never mind…" Lily blushed from the embarrassment. There is no way she would explain to her friend what does it mean to 'touch yourself'. "... Anyway! Let's quickly go to the locker room and dress into something! If somebody founds us like that, it would be a disaster! I don't want for people to think that we are some kind of perverts!"

"Yes, you are right!" Amelia responded first, and, in her ignorance, she headed out of the gym class first, while still covering only her front body, giving her friends a clear view of her wide back, as her plump buttocks jiggled and clapped against each other, making a soft, slapping sound.

"C-come one, Berry, let's get dressed…" Lily said to her friend while standing above her. Berry looked up, revealing her face, now redder than before from the sudden truth spoken by the bird. Seeing her beautiful, naked friend in all her glory above her, made her feel something else, too.

"Alright…" she got up, pushing her hands hard against her body, and left the gym class together with Lily, walking side by side, both trying their best to not look at their friend's nude body. But Berry couldn't hide a faint, hot feeling she sensed since they became stripped of all of their clothes…

"After you dress up, there is a lot to talk about." They heard, and spotted the black bird following them.

"Shut up! It's your fault we even got into that situation! How could you just let our clothes be destroyed by this weird… transformation."

"It was either that, or you would become a meal for the Slime Libido. And if there is nobody to beat others, even more girls will suffer a similar fate to yours, but with no one to save them."

"Then… why won't you just transform others into those… magical girls?" Berry asked quietly, as they were walking slowly through the corridor.

"I don't have that much power available. Also, your trio is exceptional. With such a strong bond between you, you could become compelling." They entered the locker room, where they finally felt a little safer. "And there is no time. You need to become strong, fast, or even while fighting three versus one you will stand no chance. A very powerful Libido is somewhere in this city. A threat to all of you..."

The girls ignored the bird's gibbering, as for now, getting dressed was clearly the most urgent matter for them, not some "libidos" it was talking about.

"Thank god, I still had my gym clothes in the bag!" Lily and Berry were welcomed in the locker room by an already fully dressed Amelia, who just finished pulling a simple white shirt above her head. Her bottom was covered by the short bloomers, but the lack of underwear made her shapely buttocks quite visible, not to even mention the front of her chest…

"Berry, do… do you have any spare clothes?" Lily asked.

"... I had gym classes in the morning, so I also should have my white shirt and bloomers. What about you?"e

Lily blushed hard and gazed at the floor. It was quite obvious by looking at her that she had no such luck as her friends.

"M-maybe we could share somehow?" Berry suggested, feeling bad about seeing her humiliated friend in such a state, even if it was quite hard to get your eyes off her, with that slim, long figure…

"Oooh! I also have my tracksuit! I like to wear it during running training!" Amelia came before them, presenting a single upper part of the tracksuit with a hood. It was a considerable size, since it had to fit Amelia's breasts inside, but the lack of the bottoms made it a little… risky. Lily looked at it with disbelieve, but since she had to choose either that, or full nudity…

"Better than nothing." She snatched the cloth from Amelia's hands and quickly slipped her hands inside it, uncovering her body for a couple of seconds. Berry's curious eyes went for a quick glimpse between her legs, and she learned that her friend was completely bare out there, just like her…

The tracksuit was a couple of sizes too big for lean Lily, but her height made up for it, making the borrowed outfit reach to almost her knees. Maybe people will think she is wearing a very short skirt, or some kind of shorts. Not something that Lily she knows would wear, but what other option did she had? She zipped the tracksuit up, hiding her small but perky A cup breasts.

"... Berry? Aren't you going to dress up?" she asked and pulled on her only cover, for it to hide the most of her bare, long legs.

"Oh," Berry gasped, as if she only just realised she was the only one left completely naked. "R-right…" Berry moved to her backpack, crouched down a little to not uncover any part of her naked body, grabbed it and went to one of the cabins with toilets, while walking slowly with her back pressed to the wall. She didn't want to give her friends any view of her ass, like Amelia did.

She closed the door after entering the cabin and opened her backpack. With a white shirt and gym shorts, she felt a lot safer, although she couldn't ignore the fact how much of her breasts were visible. Not to mention the obvious shape of her buttocks… being in such revealing clothes made her feel weird, but not as weird as being completely unclothed before her best friends. Sure, they did bath together when they were younger, but now they are a lot older, and their bodies look entirely different from back then. All those curves and shapes… but their most important parts still look the same, bare, with no sight of any hair. Are they shaving, or just not growing anything there…?

"Berry! Are you done? I want to change my clothes as soon as possible!" Amelia said loudly, making her twitch a little from surprise.

"I… I'm done." While still feeling quite embarrassed about her thoughts, she joined her friends. Amelia dressed just like her, without underwear, wearing just some gym clothes on, and Lily, completely exposed from the waist down. Berry looked at her small feet, with painted black toenails…

"We… don't have shoes," Berry just realized after looking at her exposed friend.

"Just be glad that you at least have some shorts on," Lily commented with disdain in her voice. "What would my parents say if they saw me like this…"

"You are done then, I presume?" The bird, who was looking at them from the top of one of the lockers, finally spoke after seeing them get dressed. "This is not as bad as you would think, as wearing such humiliating clothes generates a faint sexual energy, from the embarrassing feeling you are getting. It will be used as an energy for your next encounter.

"What do you mean next?! There is no way in hell we are doing any of that stuff you talked about!" Lily responded furiously.

"What?! You don't want to be a magical girl, Lily?!" Amelia shouted in surprise, with an extremely defeated face. "But it's like… our destiny! Us three, being a magical girl, just like in The Trio of Magical Girls!"

"What does that cartoon has to do with anything?!" Lily pulled on the front of her borrowed tracksuit a little too much, giving Berry quite a good look at her upper thigh, and even the lower buttock.

"We would be the saviours of the world! Defeating bad monsters and saving people! Who wouldn't want to do stuff like that?"

"We are in high school, Amelia, not in some magical world where being a magical girl exists! We need to think about our future!"

"And what future would there be if some monsters take over the world!" Amelia looked hastily at the bird, and then at Berry, looking for some assistance.

"I… I guess…" Berry just mumbled, not being good at arguing like that.

"See! Berry agrees with me!"

"We don't even know what that stuff means! We don't even know what that is!" Lily pointed her finger at the bird, who was calmly observing the little exchange between them.

"I'm an inhabitant of a planet called P'enua. I came here by an order of my superior to find and capture rebel of our race, who in his pursuit of power came to Earth with his own deviant plan. He plans to plant seeds of Libido on Earth, who would slowly rise in power by consuming sexual energies from humans, until he poses an army strong enough to take control of the entire planet, from which he would be able to send attacks to our home-planet with his Libido monsters. My mission was to arm suitable residents of Earth with purity powers, an opposite type of power, with which they would combat them. Most adults are suitable for that mission, since they possess a lot more sexual energy than purity energy, while children have too much of purity energy than sexual energy. I had to find something in between, and I realized that humans at your age are a perfect combination, even if sometimes they do possess a little more of sexual energy than others." His gaze moved to Berry, who in response shrunk a little in place. "I studied human's interest based on a person who I found most suitable - same amount of purity and sexual energy in their body, to make the power I would give most suitable to the user." Now his head moved in Amelia's direction. "But it seems I misjudged the person who I was learning about humanity interest, considering the reaction of you, unless you are a weird one out of the humans." And now his little beak turned to Lily.

"What?! You mean all those clothes and this magical girls stuff is because she is interested in those?!" She pointed her finger at Amelia. "She is like… absolutely not the perfect example of a "typical teenager girl! None of us are!"

"Heh…" Amelia blushed and scratched her chin in embarrassment.

"So… our… planet will get conquered if not for us?" Berry asked.

"Precisely."

"Oh, come on, this is stupid! There is no way some kind of alien would get to our school from all the places possible! And you are saying you are letting three young girls decide the future of your entire world? Is this some kind of joke?"

"Considering that not only my planet would get in trouble, but also yours, and even sooner than later, yes, I think you will want to help save your world." The way the bird said it made them all shiver. Would those black, slimy things really take over the Earth, if they don't become some… magical girls? It sounded so…

"It's like a dream come true!" Amelia jumped with excitement, making her front go suddenly up, and then down. But when she looked at her friends, they didn't look as convinced as she was. "You can't say you are not going to do that! The entire world needs our help! Will you just abandon everything? Lily won't become a doctor if the entire Earth is conquered by animals! Don't you agree, Berry?"

"I… I guess…" That also meant their friendship would maintain, or grow even stronger, as they would need to save the world together… but maybe the stakes were higher than that, and she shouldn't have such selfish thoughts right now.

"Then it's decided!" Amelia exclaimed loudly, with her fist in the air. "We are now magical girls! We are going to fight injustice and help people in need, together, as a team!"

Amelia, by far, was the most enthusiastic out of the three of them about that opportunity that arrived at them. Lily was straightforwardly not happy about it at all, while Berry was unsure whether what happened was a good thing, or not.

"... Can we just go home now? The less I'm like that, the better. Can we discuss the details later?" Lily let out a tired gasp and looked at the bird. "Where can we meet with you tomorrow? To talk about details?"

"That won't be necessary." As the bird spoke those words, the sudden light engulfed it, and second later, it was gone. "I can do something like that, which will make it a lot easier to communicate with all of you at once." Before them appeared three small figurines of a black bird, like some souvenir from holiday. "You can carry me like that or pin me to your backpack or purses. Like that, I will always be with the three of you."

"Awesome!" Amelia grabbed the first one and put it near her face. "So cute!"

"So lame." Lily grabbed hers and had a brief look at it. "I guess they won't be that suspicious, most of the people have stuff like that pinned to their bags. And we are friends, so having the same type won't be that weird."

Berry grabbed hers in silence.

"So… do we return home now?" Berry asked, looking at her friends. Lily looked down, to her exposed legs, and became flushed.

"Yea…. let's just… go. As fast as possible."
