Let's do this!
Arnold was still blushing awkwardly as he looked towards Lulu, who was playing around with her braids. Arnold coughed as Lulu turned to him in curiosity. "Hey, Lulu, I always wondered... in your country, do you have a swimming pool?"
Lulu gave a smirk as she said, "No pool, but we do have a nice watering hole to swim in. Why ever do you ask?"
"Uh... well... no reason." Arnold said, turning away as his eye caught a returning Lila, whose face looked like it was sopping wet. "Oh, there you are, Lila!"
"Goodness, what happened to you?" Lulu looked over towards Lila in concern.
"I had a little trouble with the water fountain." Lila said. "I'm guessing there's a bit of a loose screw or something, because the water sprayed all over my face."
Arnold started to open his mouth, about to ask something before Lila answered for him, "And don't worry, I dried myself off, Arnold."
"Oh... okay..." Arnold said as he looked towards the sisters. "Well, uh... shall we continue?"
The sisters nodded as Arnold started to lead them more and more towards another part of the town. Helga, who was only watching from a nearby distance, snickered as she quickly followed them.
"Deep humiliation... but that's just the beginning, Lila!" Helga smirked as she rubbed her hands sinisterly as she kept following the three... unaware of the other person following her... a very lovesick Fifi, staring straight at Helga's face.
"She looks very sexy when plotting... but she is hurting my friend's sister... and did I hear her mention something about love? Poor dear must be confused..." Fifi sighed. "Well, if I can just get her alone..."
Fifi shook her head as she kept following Helga.
Eventually, the trio reached Slausen's as Arnold gave a smile. "Now, this is usually a hang-out most of us go to when we're either hungry or just wanting a small shake."
"It's true. Slausen's has the best milkshakes you've ever tasted, Lulu." Lila smiled.
"Hmmm... I wouldn't mind a nice vanilla milkshake myself." Lulu smiled as she glanced her eyes towards Arnold. Arnold noticed Lulu's eyes, but ignored them as he turned with a smile.
"How about I order you girls some milkshakes, then? On me?" Arnold smiled as the three entered inside.
"Er, how about I order the milkshakes? You two can go ahead and wait for me." Lila smiled as she showed Arnold and Lulu to a table as the two of them sat down.
"Are you sure? I can-" Arnold started before Lila sighed.
"Arnold, I'm very capable of ordering the milkshakes. You just keep an eye on my sister, okay?" Lila smiled. "Now, vanilla for Lulu, and what would you like, Arnold?"
"I'll... take vanilla as well." Arnold said, looking a little disappointed, much to Lulu's notice. She smirked to herself, knowing that Arnold won't be disappointed for long.
"All right then. I'll be right back." Lila said as she started to go over to the counter. The three were unaware that someone else had also entered and when a certain someone overheard Lila, she smirked as she pulled out a bottle of something from behind the counter and carefully crawled towards the kitchen and entered through the doors.
Arnold watched Lila as she went over to the counter to ask for the milkshakes. Lulu, smirking and seeing an opportunity, pulled out a small bag and dropped it under the table on purpose. She started to go upside down (feeling pretty lucky that nobody else would see them) as she said, "Whoops, I think I dropped something."
Arnold, hearing that, turned to Lulu as he said, "Do you n- uh..."
Of course, an interesting thing about someone trying to get something to pick up in a booth... when you have to go upside down, a woman's skirt would eventually fall over... people may think that skirts just magically stay in place, but that's just a thing that happens in cartoons. No, in this case, Lulu's skirt started to go a bit backwards, revealing white lacy panties. Arnold's eyes widened as his mouth was starting to form a bit of drool.
"Wh-what am I doing? This is wrong! This is Lila's sister! You just met her! Stop staring at her nice, clean... er... wonderful, looking panties..." Arnold lost his trail of thought as he felt a blush coming on...
Upside down from her position, Lulu had managed to grab the bag, but managed to stay upside down for a bit longer as she looked up under his sweatshirt as she smirked. "I wonder if he's feeling a hard-on down there..."
"It's got to be here somewhere..." Lulu said, acting like she was still trying to reach for the item. She crawled over to Arnold's side of the table to catch a glimpse as she noticed Arnold's staring face from above. "Oh ho! I knew the panties would catch his attention! And my, my, is he starting to form a nosebleed? I think he's starting to form a nosebleed! Hmmm... maybe if I wiggle it in front of him..."
"I think I can... reach it..." Lulu smirked as she started to wiggle her butt around, in front of the blushing Arnold.
Arnold gave a happy smirk to himself as he thought, "Whoa... Lulu is certainly making herself inviting..."
His eyes widened as he tried to avert his eyes. "Dang it, Arnold, this is like what happened two years ago! Look, don't touch, look, don't touch, look... er... look... maybe one touch wouldn't hurt."
As if by instinct, Arnold's hand started to lift up on its own as it was about to get near Lulu's panties. Lulu gave a warm smirk to herself as she could hardly believe what was happening.
A couple of minutes earlier, Helga had leaned in from the kitchen as she overheard Lila's order.
"Two vanilla milkshakes and one chocolate for me and my friends over at the table." Lila said.
"One chocolate for Lila, huh?" Helga smirked as she noticed a bottle of hot sauce nearby. "Well, we'll see who's laughing soon enough!"
Helga quickly crawled towards the kitchen and entered as she hid behind the door. Pretty soon, the drink maker got the order as he started to mix Lila's drink first. As soon as Lila's milkshake was finished, he put it to the side as Helga grabbed it and quickly started pouring hot sauce inside the chocolate milkshake as she smirked. "Hot meet cold!"
Little did Helga realize was that Fifi was watching her in mere wonder, making mental notes. "Monkey wrench... hot sauce... oh, I can see the many possibilities with this!"
As soon as Helga felt satisfied with her pouring, she put the lid back on the milkshake and put the milkshake back on the serving tray... just as Lulu's milkshake was finished.
"And now... to watch the fireworks!" Helga said as she smirked.
Lila was patiently waiting for the milkshakes as she hummed to herself. Sure, she felt a bit satisfied that Arnold probably won't be chasing her any time soon, but at the same time, she did kind of felt bad for lying to Arnold like that. Still, if her sister liked him, who was she to complain? Lila gave a small giggle to herself as she thought of the idea possibility. "Arnold and Lulu... if he treats her right, I can see them as a perfect couple..."
It was at that moment Lila turned to the booth where Arnold and Lulu were... she squinted as she couldn't quite see them from her position, so she had no idea what they were doing or even talking about. Curious, she decided to check up on them.
"Come on, Arnold... feel me..." Lulu smirked as she noticed Arnold's hand was getting so close... but then her head turned and her eyes widened as she saw Lila getting up. "Whoops, time to wrap it up!"
"Oh, there we go!" Lulu said as she was going right side up, Arnold's hand stopping in mid-air as Lulu pocketed the bag. "Can't leave home without my purse!"
Arnold shook his head as he smiled, putting his hand back to his side. "Yeah, wouldn't want you to leave home without it!"
Arnold chuckled nervously as he thought to himself, "What is wrong with me? Why did I have the same urge I did two years ago? I thought I was over this phase after Miss Vail!"
"Hey, Arnold, Lulu! Wanted to check up on you to see- oh, goodness, Arnold, your nose!" Lila gasped as she pointed to Arnold's nose. "What happened?"
"Huh?" Arnold blinked as he noticed the nosebleed.
Lulu innocently said, "I'm sorry, Lila, that was my fault. He was showing me the salt and pepper shakers, and I accidentally threw one of them at Arnold and he got this nosebleed."
Arnold blinked in confusion towards Lulu, but deciding to take advantage, smiled nervously. "Er, yes, of course! It caught me by surprise, it wasn't your fault, Lulu."
"Still, I'm ever so sorry, Arnold." Lulu said, looking sad.
Arnold raised an eyebrow, wondering why Lulu would be willing to help Arnold lie to Lila... until his eyes widened. "D-did she notice that I stared at her butt? And... her wonderful panties? Oh no..."
"Well... here... hope this helps." Lila said as she handed Arnold a napkin, believing the lie.
"Gee... thanks." Arnold said as he accepted the napkin from Lila (much to a now watching Helga's frustrations) as he started to dab the napkin on his nose, getting rid of the blood.
"Milkshakes for the three!" The waiter said as he came over, delivering the milkshakes. Arnold decided to accept his milkshake without further question as he started to sip on it nervously. Lulu took her milkshake as she started to have a calm drink as she was carefully calculating how to ensure the final bait gets settled. Lila took her milkshake and started to sip on it... but blinked as she felt her mouth starting to tingle.
"This tastes a little funny... like it's hot and cold at the same time..." Lila frowned as she started to click her mouth, trying to feel the taste, but it somehow didn't feel right.
Helga smirked to herself. Yet another way to dissuade Arnold from Lila... if this doesn't convince Arnold... then her next plan probably will...
Next chapter will have Arnold and Lulu alone together! Don't worry, things will eventually begin to heat up!
