The Powerpuff Girls, at the age of eighteen, were patrolling the city for any form of suspicious activities. The sky was very cloudy and gray, almost as if it was about to rain. So far, the girls have seen nothing of interest.

"Hmm... So far, no sign of any criminals." Blossom spoke. "Still, we should keep our eyes peeled."

Buttercup then said in complaint "Blossom, we've been scanning the city for nearly half an hour. There hasn't been any bad guys around for us to beat up. I could've used the time we wasted to have sex with Brick."

Bubbles then spoke "I'm feeling tired. Can we go home now?"

Blossom let out a sigh of annoyance before saying "Okay, okay. I guess we've done enough patrolling for today. Let's head on home."

"Hurray!" Bubbles cheered.

"Ugh, finally." Said Buttercup in exhausted relief as the girls flew away from Townsville straight to their new private home which was located near the beach coast.

As they flew, the clouds formed even bigger and it started to rain, causing the girls to get all wet. "Oh no! It's raining!" Said Bubbles, covering her head from the rain

"Aw, shit...! I just had these clothes cleaned." Said Buttercup, trying to keep her head dry.

Blossom was annoyed of this as well. "So much for clear skies." Blossom then felt as if her legs were feeling colder, in fact, she felt as if the rain was dripping past her clothes and on to her skin. "What in the world?!" Blossom looked at her legs and her eyes widened in shock.

Her pants were deteriorating right before her eyes. The girls stopped and looked at their bodies, seeing their clothes disappearing. "What the fuck?! What is going on?!" Buttercup questioned.

Bubbles covered her exposed areas as she cried in terror "Eek! Our clothes are expiring!"

"No, Bubbles. They have returned!" Said Blossom with a serious face.

As their clothes kept on getting deteriorated, Bubbles looked at Blossom with a blanked expression and asked "Um, wait, who has returned?"

"She's talking about the Nanobots that come from the rain, Bubbles!" Buttercup answered. "The same ones that ate our clothes when we last fought them?! How could you have forgotten about them?!"

Their undergarments began to get eaten away as well as Bubbles said in realization "Oh yeah. That one time when we were completely naked. I remember now!"

"There's no doubt that they are here for some payback!" Said Blossom. "Unfortunately for them, we have been doing some training, so that we can fight microscopic enemies!"

"Yeah, let's beat these tiny bastards!" Said Buttercup as the girls began swinging their fists and legs around, actually managing to destroy every nanobot that came in contact with their attacks.

The girls were now completely naked when they managed to destroy all the nanobots. Blossom looked around, seeing tiny debris as she confirmed "I think we've chased them off."

Bubbles threw her hands up, causing her exposed breasts to jiggle as she cheered "Yay! We did it!"

Buttercup pumped a fist as she said "Hell yeah! We totally crushed them to robot bits!" She then noticed that she was in the nude, much to her annoyance. "It's too bad that all three of us are naked, now."

"Yeah, at least we were high up in the clouds when they ate our clothes and underwear. Otherwise, we would've been left humiliated." Said Blossom. "We might as well head back home and get some new clothes."

"Or we could just stay naked." Bubbles suggested, causing her sisters to look at her with raised eye brows.

"Stay naked?" Blossom and Buttercup asked confused.

"What do you mean stay naked?" Blossom asked.

"Well yeah, I mean we are very high up where nobody can see us with clouds covering us." Bubbles pointed out.

"What are you getting at, Bubbles?" Buttercup asked.

Bubbles made a giggle as she suggested "I was thinking, why not play tag in the nude?"

"Play tag, in the nude?" Blossom questioned. "I don't know, Bubbles..."

Bubbles then added "We can go and find some secluded areas to play. Like the beach, or the woods, or even way up here in the clouds!"

Buttercup cupped her chin with an intrigued smile as she said "You know what, Blossom, Bubbles might have the right idea."

Blossom looked at Buttercup with an annoyed expression as she said "It figures that you would be interested in an idea like this."

Buttercup turned her head to Blossom and said "Oh, and you aren't?"

Blossom then tried to explain her concerns, saying "I'm just thinking of the chances of us being seen and..." The redhead leader was interrupted by a sudden playful slap on the buttocks, which cause her to yelp. "Ah! Hey!"

Blossom covered her rear-end as she glared at Buttercup who looked back at her with a sly smirk. "Tag, you're it!" The brunette exclaimed as she flew away.

"Looks like you're going to have to catch us, Blossom!" Said Bubbles as she too flew as fast as she could from her redhead sister.

Blossom then made an irritated groan as she cried out "You two are impossible! You know that?!"

"Yeah? Well at least neither one of us is a party-pooper like you!" Buttercup called back in a teasing manner.

Blossom then had a face full of determination, saying "A party-pooper? Me?! We'll see about that...!" She then jetted after her sisters as fast as she could.

Bubbles took notice as she said "Looks like we've managed to persuade her, Buttercup."

Buttercup looked behind, seeing Blossom coming after them. "Yup, she's chasing us while all wet and naked. Pretty hot, if not sexy."

Buttercup and Bubbles descended from down to the beach, which was deserted for the time being, while Blossom followed in suit. All three girls felt the cold wind blow on their exposed bodies, hardening their nipples and clits which filled each of them with an arousing adrenaline.

Blossom felt her frustration subside after feeling the cool air all over her exposed body. "Huh, I hate to admit it, but flying around naked in the cold air feels really good. It's a rather... riveting experience."

Bubbles giggled as she exclaimed "Tag is so much fun when we're naked! I'm getting goosebumps all over, and I can feel our nipples and clits getting so stiff!"

"Me too!" Said Buttercup, Buttercup then held Bubbles by the hand, guiding her at a certain direction "I've got an idea how we can lose Blossom!"

"Really? But where are we going?" Asked Bubbles.

"First, we'll create a little sandstorm, then..." Buttercup instructed what they were about it do in Bubbles' ear, causing a smile to stretch on her face. "Are you ready?"

Bubbles nodded, saying "I'm ready when you are!" The two sisters then landed their feet hard on the Sandy hills, causing the particles to block Blossom's view.

Blossom found herself caught in the sandy cloud before she could react. She covered her eyes as she complained "Oh yeah, that's really fair, girls! Really!" She then heard splashing noises. She twirled herself around like a top, blowing away the sand so that it would be clear. Blossom looked around, seeing that her sisters were nowhere to be found. "Darn it! Where could they have gone? Wait a minute..." Blossom then looked at the ocean, reminding herself that she heard a splashing noise. "So they're hiding in the ocean, huh? Very clever, but they'll have to come up for air, eventually."

While Blossom waited for her prediction to be right, in reality, meanwhile, her sisters were actually hiding in a near by cave. They both giggled as Bubbles whispered "It worked, Buttercup...! She's totally falling for it! She really thinks we're in the ocean...!"

"Yup, it's safe to say, we've outsmarted our smart sister, Blossom...!" Buttercup commented as she made bedroom eyes at Bubbles, running her right hand all over her blonde sister's breasts. Bubbles made the same eyes at Buttercup as she in turn caressed Buttercup's breasts. "So while Blossom waits, how's about some sisterly sexy time?"

"Mmm...I'm all for making love with you, Buttercup. Especially in a cool cave." Said Bubbles as she and Buttercup brought their lips together in sweet kisses. Their hands reached for each others vaginas and began rubbing one another gracefully. "You know, I'm pretty glad those nanobots came and ate all of our clothes."

"Me too, Bubbles." Said Buttercup, pecking Bubbless lips. "I've been feeling so horny lately, that I was relieved to have been forced to be naked with you and Blossom." Buttercup placed another kiss.

"I've been feeling horny, too." Said Bubbles, sharing more kisses. "And even though I'm not having sex with Boomer, having sex with my sisters is just as romantic!"

"I feel you, sister, both mentally and physically!" Buttercup responded. "Let's rub our pussies together."

"Yes, let's." Said Bubbles as both sisters lifted each other's right leg over their own left hips and began to slowly rock their hips back and forth, gracefully rubbing their vaginas together. Buttercup and Bubbles moaned softly while feeling their genitals slip and slide against one another. "Oh yeah...! Your pussy feels so good, Buttercup...!"

"Your pussy feels good too, Bubbles...! Oh, fuck yeah...!" Buttercup said softly as she and Bubbles savored the sensation.
