Chapter 9

The curious plumber and princess barged inside the guest room and gasped as they watched the two, completely baffled at what they are doing right now.

"What the-," Mario mumbled with a raised eyebrow.

"Oh my God," Peach gasped.

They noticed Toad sitting on the floor and his eyes closed with a very satisfied expression since Toadette's hands were rubbing around his bare feet. She turned to watch the confused look on Mario and Peach's face and smiled at them. "Hi guys!"

"T-Toadette?" Peach spoke. "What're you two doing?"

"Duh, can't you see I'm giving Toad a relaxing foot massage. It's something I've been planning for him since he keeps telling me that his foot hurts everyday."

"Ohhh, yesss," Toad groaned in satisfaction.

There was a long pause.

"B-But... I thought you two were doing...," Mario trailed off.

Toadette watched him with wonder. "Doing what?"

"Y'know..."

Peach rolled her eyes. "We thought you two were having sex, Toadette," she finished.

Suddenly, Toadette instantly stopped what she was doing and Toad opened his eyes as they stared at them. "What's...sex?" Toadette questioned. "Is that a sport?"

"No, its a game right?!" Toad butted in.

Mario shook his head as Peach giggled sweetly at their extreme slowness. "Are you two serious?" She smiled. "You really don't know what sex is about?" The toads nodded negatively at Peach's question, completely oblivious to what she is talking about. "Then don't worry about it, someday you two will find out."

The two shrugged at this awkward situation as Toad got back up on his feet and jumped in his brown shoes. "Well, anyway, let's get back downstairs, guys. It's now 12:45 and I have a strong feeling that this game is probably-" he stopped his sentence since they all ignored him and already exited the guest room to make their way downstairs. "Oh great...," he groaned in frustration.

Back downstairs, Rosalina was busy cleaning up stains of blood around the floor from Candy and Mona's recent rumble, shaking her head since she regretted not preventing the fight from even happening. "Note to self: Never ever come to another all-girls slumber party ever again, EVER!," she grumbled to herself. Candy was sitting on a nearby couch with a large icepack on her jaw, moaning in serious pain while Mona was sitting next to her, rubbing some alcohol around her arm to aid the small cuts on her arm.

"Heh heh heh! Mona wins this time!" Wario cheered with glee. (his erection subsided several minutes ago)

DK only groaned and crossed his arms. "Hmph...yeah, yeah whatever. Just take it and leave me alone," he grumbled, handing him 80 coins. Waluigi noticed this and rushed there immediately.

"And ten percent for his brother," he jumped in, already throwing his hand out to get some cash as well.

DK growled at him, knocking him out with just one punch to his nose then making his way over to comfort his bruised girlfriend. Wario gazed at Waluigi's unconscious face but shrugged and went to count his cash instead.

"Wow, its a good thing we came down here and stopped those two, Daisy," Luigi uttered. "They could've killed each other!"

"Yep!" she replied, staring at the busy star princess near her. "Look, you missed a spot," Daisy spoke, pointing at somewhere on the floor.

Rosalina growled silently and continued cleaning, watching Peach and Mario walk downstairs along with Toad and Toadette behind them. The princess suddenly froze and gasped since she noticed the damaged girls and blood stains on her floor. "Wh-What happened in here?"

"Candy and Mona happened," Rosalina replied with no expression.

"Oh, God. Again?"

"Yeah..."

Mario strolled over to Waluigi's body on the floor and placed his hands on his hips. "Something tells me that he is not sleeping."

"Heh heh, DK knocked him out," Wario chuckled, still counting his coins.

"Oh, boy," the plumber shook his head.

Then that's when Pauline came downstairs, rubbing her head gently from her collision with Peach's bedroom door. "W-What did I miss?" she mumbled.

This caused Peach and Mario to only laugh at her. "A lot," Peach replied.

Pauline caught on to what she was talking about and scoffed at her. "Oh whatever."

She turned her attention to the short plumber. "You just don't know what you're missing out on, Mario," she said to him, giving him a seductive wink.

Peach growled instantly and was ready to rush after her but Mario was lucky enough to stop her in time. "It's not worth it."

She smiled and thought of a very interesting idea. Grabbing Mario's face, she stared at Pauline and aggressively kissed his lips, shoving her wet tongue inside his mouth to mingle inside. The pretty brunette gasped at this and turned her gaze away while everyone there watched attentively at the makeout session. Peach broke away from the kiss and smirked since she knew that she won this battle, imprinting a deep kiss mark around the plumber's lips.

Daisy was instantly aroused from this and carelessly kissed around Luigi's neck but was stopped by him quickly. "What're you doing? We can't do this here."

She giggled. "I love a man who refuses."

"Aren't we supposed to be doing something. I mean, we all found you girls in time."

"I'm getting to that, sweetie," she whispered. She stood up and faced everyone since she was ready to make an announcement. "Okay boys, you all did good trying to find us and we're all very impressed."

Wario smirked. "So that means we're in?"

"Yep," she replied with a smile. "Time to party!"

The boys cheered with excitement now that they finally have the chance to spend the night with the girls in their slumber party. Peach on the other hand, still didn't agree to all of this. "Daisy are you serious?!" She butted in. "Did you forget that I'm still hosting this party?"

"Aww c'mon, Peach, they're just boys."

"And that's the problem!"

Daisy rolled her eyes. Before she was about the say anything else, Mario interrupted their conversation and kissed Peach's lips. She was startled from his sudden action and they parted lips seconds later. "Wow, thanks for letting us stay with you girls, Peach. You're the best!" He said before leaving to re-join with the guys.

Mario's words caused the princess to blush deeply and Daisy smirked. "Well," she uttered. Peach noticed her sneer and finally gave in.

"Okay, you win. They can stay."

Daisy grinned and bearhugged her blonde friend with excitement. "Yay!" They overheard a cry near them and realized Rosalina's pajamas around her legs, now exposing her underwear.

"Hahaha! Take that!" Toadette mocked since she just pantsed the unaware star princess. Everyone there all laughed and giggled at Rosalina, all except for Daisy since just realized that she was wearing one of her panties.

"Wait a minute... is that my underwear? H-How?" she questioned. Everyone there suddenly stopped and watched the confused but upset look on Daisy's face. She paused for a second, remembering the loss of her Swell Mushroom that Wario actually stole. "It... It was you! You took it!"

Rosalina was completely puzzled as well since she has absolutely no idea how she is wearing Daisy's underwear or what she is talking about. "Me?! What did I do?" she shot back.

"YOU TOOK IT!" Daisy screamed with rage, now forming her hands into a furious fist. "I'm gonna kick your ass!" she screeched, dashing after Rosalina and tackling her to the floor. This turned out into a rough cat-fight in the castle and the girls gasped while the guys, except Luigi, smirked freely. He tried to break up this unexpected altercation but failed to do so.

"30 coins that Rosalina wins," Candy assumed.

Mona shook her head. "30 is too much, I got 15 on Daisy."

"Broke ass...," Candy mumbled.

"What?"

"Get your ears cleaned, sweetie. I don't repeat myself."

Her words caused Mona to growl, she immediately tackled Candy and wrestled with her for the third time.

Peach quickly rushed over to stop this but was tripped by Pauline and fell flat on face on the floor. "Hahaha! You better watch where you're going, princess," she scoffed, teasing Peach with a laugh. This was the last straw. Peach growled and got up on her feet then threw herself at the brunette, knocking her down to the floor and jumped on top of her as they too created another cat-fight in the castle.

"What the hell is going on here?" Wario cried. The guys shrugged at his question since they also have no clue what happening.

"Stop it, girls! Stop!" Toadette cried but realized this was no use. She had no other choice but to try to break up the fights but failed many times.

"Um...," Luigi muttered. "What now?"

"I think we should just leave," Mario replied.

"Yeah, you may be right," Toad jumped in.

"I'm not in the mood to party anymore...," DK admitted.

"Yeah, let's go," Wario finished, grabbing Waluigi's unconscious body and throwing him over his shoulder.

They all exited from the castle and left the girls to continue the noisy commotion back inside. Toadette noticed when the guys left and peeked through the castle's windows, smiling. "Okay girls, they're gone." They instantly ended their fights and got back on their feets, smiling along with Toadette.

"It's about time," Candy spoke.

"What a nice idea of letting us all fake a fight so that the boys will leave, Daisy. I can't believe it actually worked," Mona said to her.

"Heh, well I'm just smart like that."

"Enough talk, girls, let's finish this party!" Pauline jumped in. She noticed Peach dusting off her clothes and went to confront her. "Um, sorry about what I said before when I teased you about your relationship with Mario. I deserved that slap," she chuckled faintly. "What do you say? Friends again?"

"Yeah sure," she replied with a smile.

They hugged and the girls awed to see this happen once again. Daisy smirked and moved over to the same secret light switch from before. As she turned on the switch, the lights once again dimmed and pop dance music played in the background this time, the same pole came from the middle of the floor, and the disco ball dropped from the ceiling, filling everywhere with colorful and cool lights. "Let's finish what we started, girls!" She announced, already dancing on the long pole while all the girls screamed with glee. The slumber party continues, with all of the girls enjoying themselves to this successful event, dancing along with each other into the late night. They have absolutely no plans of falling asleep anytime soon.

The guys were busy walking back to their homes, completely disappointed that their chance to party with the girls failed.

"Oh, well there's always next time, right," Toad hoped.

"Ha, yeah right," Wario snorted. He heard Waluigi mumble from his daze and noticed him waking up.

"Eh? What the- What's going on here? Where am I?" He mumbled again.

Wario noticed this and punched his nose, forcing him back to sleep since he knew Waluigi would be very upset to realize what's happening right now. "Goodnight Waluigi."

"Ahh, goodnight to you too, mommy," he sighed before drifting off to dreamland.

"Well, I had fun," Luigi told his brother.

"Yeah, me too," Mario replied with a smile.

"Y'know, maybe one of these days us guys should have something like what those girls had but not a slumber party though, something very cool and different.

"Hmm, maybe you're right, Luigi," Mario agreed. "Maybe we should."

DK raised an eyebrow since he now realized something just doesn't add up. "Why do I get the feeling that we're missing something," he wondered as everyone stopped to wonder what is he talking about.

"What I'm missing is my chance to party with Mona!" Wario exclaimed.

"No, no, something else. It's green, with a big nose, can eat almost anything, and lays eggs.

"Hmmmm...," the guys hummed trying to figure this one out. They just shrugged it off and continued walking.

Back at the castle upstairs in a random guest room, the sounds of a bed squeaked rapidly as sounds of sweet moaning echoed around the area. A pink creature suddenly emerged from under the bedsheets, breathing heavily after numerous rounds of lovemaking with her lover.

"Wow...," Birdo sighed in happiness. "How long have we been in here?"

Her lover then showed his face and smiled at her. "Three hours," Yoshi replied.

Her eyes widened at his reply. "Oh my God, really?"

"Haha yep! But I still got more energy for another round."

She narrowed her eyes and pulled the covers over them, engaging them into another round of passionate lovemaking together once again. As this continues on in the guest room, they were completely unaware of a tiny hidden camera mounted on top of the curtain rod near them. Is someone spying on them?

Somewhere from parts unknown in the Mushroom Kingdom, inside an ominous castle surrounded by burning lava and flying Magikoopas, we find a large green shelled Koopa with spikes and horns inside an underground control room, filled with numerous monitor screens. "Good, good...," he chuckled, rubbing his hands together mischievously. Each monitor displayed various areas around Peach's castle, showing around Peach and Daisy's bedroom, inside Peach's car, all of the bathrooms and random guest rooms, even downstairs where all of the girls are busy partying. "Well, this was very entertaining tonight, those idiots had no idea that I hid random cameras everywhere and saw each and everyone of them had fun with each other, heh heh," he muttered. He smirked and continued his attention on the girls while they party and enjoy themselves. It looks as though this villan was the real Sleepover Spy.

The End

Hmm... I wonder who was that large Koopa dude that was spying on them. O_O
