Time for another round!

After paying for the milkshakes and leaving for the bus, Lila was still clicking her tongue, as if she wasn't tasting anything right. Arnold looked over to her in concern. "Are you okay?"

"Arnold, I am ever so all right." Lila said as she still clicked her tongue.

Arnold paused... before turning his eye toward Lulu, who only gave him a warm smile. Arnold paused as he said, "There's only one more stop to make that I can think of... I hope that's all right with you two."

"Anything is all right with me, Arnold." Lulu gave a smirk as she thought to herself, "He's probably going to want to talk to me alone... and this will be the moment I strike!"

From nearby, Helga was sitting behind three seats away, as she kept an eye on Lila, giving a smirk. Unaware of any of them was near the back of the bus, Fifi was keeping her eye on Helga as she raised her butt off her seat. "She has a nice ass..."

"And here we are, our last stop!" Arnold said as he, Lila and Lulu entered out of the bus. "Over near the docks, you may notice this small island, Lulu. It's called Elk Island, and there are many stories behind it."

"Really? Like what?" Lulu asked as Lila was still clicking her tongue.

"Well... there are many adventures involving that island... there was this thing about Wheezin' Ed, but it was just a myth. There is an old author of a book series who lives there too, but she's pretty crabby. There's also a war site on this place... but other than that, the island is pretty abandoned." Arnold explained.

"Oh... so... if, say, two people were alone on this island, far away from the town, they would be able to do anything they want?" Lulu asked.

"Well... technically speaking, yes, but it's a very far way to row..." Arnold explained as Lila was clicking her tongue annoyingly. Arnold sighed as he turned to Lila. "Lila, are you sure you're okay?"

"It's just... I feel some sort of weird taste in my mouth. I think I'm going to go to the bathroom and wash it off." Lila said. "Do you think you can keep an eye on Lulu until I get back?"

"Oh, don't worry about him, Lila. I can keep him company fine." Lulu smirked towards her sister.

"Thanks." Lila said as she started to run off. "I'll be right back."

As Lila left, it was pretty silent as Arnold looked over towards Lulu, who gave a smile right back at him. "Uh, Lulu, about what you said earlier..."

"What did I say?" Lulu raised an eyebrow.

"Well... when we were at Slausen's, you told Lila you threw salt and pepper shakers at my nose... but you didn't do that." Arnold frowned.

"And yet, your nose was bleeding, was it not?" Lulu smirked as she leaned closer, causing Arnold to sweat nervously.

"W-well, yes, but... why d-" Arnold blushed in embarrassment.

"Arnold, I know that while I was looking for my purse, you were staring wide eyed at my butt. The nosebleed sort of gave you away." Lulu smirked.

Arnold yelped. "L-Lulu, I am so sorry! Yes, I was looking at your butt, but it was completely by accident! I-I mean, I'm usually so polite and courteous and to stare at a girl's behind, it's wr-"

Lulu held a finger up to Arnold's lips and shushed him. "Arnold, Arnold, simmer down. You're a growing boy. It's natural for a boy to be curious about the wonders of a girl's hiney."

"Is it?" Arnold asked, surprised at Lulu, but relieved that she had forgiven him.

Lulu gave a nod. "Of course. In fact, at home, I know all about boys who grow up and get curious about butts. As they grow up, the interest eventually grows."

Arnold blushed furiously as he said, "Well... I-I-well..."

"Arnold, the first step to admitting a problem is to realize you have one. So... do you like butts or not?" Lulu asked with a smirk as she laid down on a bench, seductively.

Arnold groaned as he held his head as he said to her, "A-all right, I admit it... I have a fascination with butts... more specifically... girls' panties."

Lulu raised an eyebrow. "Girls' panties?"

Arnold nodded. "I never told ANYBODY this, but a couple years ago, I had a boarder who had this weird interest in me. Usually, I help her work in her apartment and she would examine me, and I wasn't really comfortable with her staring at me with a look on her eyes... it wasn't until one day I was working as per usual... I was working under the couch when I heard her call out to me. I got out and well... she was wearing something different than her regular clothes... that is, she wore almost nothing but a blue bra and the most beautiful panties I have ever seen in my life... and the first pair I've ever witnessed. They were bright green, with blue stripes all around them. She was bent over the fridge, trying to get something and she wiggled her butt over at me as she was trying to get something, and she told me to hold her, cling on to her hiney while she reached inside for something. That's how I got my first full feel of panties... and how I learned what panties are, because she told me to 'cling tighter' to them. And..."

Arnold looked away. "I'm sorry, I revealed too much! To make a long story short, I've been interested in girl's panties ever since. If someone wore a short skirt and bent down to pick something up, I would always take a sneak peek! Please, don't tell your sister or anybody else about this! If my friends found out I was a panty-obsessed boy, they would never look at me the same way!"

Lulu looked at Arnold sympathetically as she said, "So... when you looked at my butt and my panties... you had the urge to... touch it?"

Arnold nodded. Lulu gave a smile as she said, "Arnold, of course I won't tell anybody... but only if you do three things for me."

Arnold paused, looking at Lulu. "What are they?"

"First... I like hanging out with you... and you seem to be a great person to talk to... in fact, I want to talk with you some more. Would it be all right if I come over to your house every weekend for a sleepover, starting tomorrow?" Lulu smiled.

Arnold looked in surprise. "R-really? You don't mind? What about your sister?"

"Oh, I see her a lot, but I want to get out to be on my own... besides, we're friends, aren't we?" Lulu wiggled her eyebrows.

Arnold paused as he said, "I... I guess so."

"Number two, if you feel you have an urge to touch my butt or feel my panties, let me know." Lulu smiled. "I'm all right with you doing it, as long as you tell me."

Arnold's eyes widened. "You're actually willing to..."

Lulu nodded. "In fact, I might wear a different set of panties for each day, just so you have some variety."

"I-I don't know, I don't want to feel like I'm taking advantage of-" Arnold said.

"Arnold, believe me, I insist. In fact, number three... would it, er... would it be all right if I... kissed you?" Lulu asked.

"K-kissed me? We're nine!" Arnold pointed out.

"That didn't stop you from becoming interested in panties." Lulu smirked. "Anyway, it's just one kiss. What harm can it do?"

Arnold paused as he blushed profusely. "Uh... well... I suppose... if it's just one kiss..."

Lulu shushed Arnold as she leaned closer, her arms around Arnold. Arnold slowly leaned towards Lulu as both faces started to pucker their lips... and then...

Their lips met as Arnold felt a jolt.

And we end here! We'll check on what's with Lila and Helga next time!
