It was yet another typical day at the Loud House. Lori was in the middle of talking to her boyfriend on her smart-phone, Leni was working on more designs for her dresses, Luna was rockin' some new jams, and Luan was brainstorming on some new jokes. Lana was playing with her pet iguana, Lola was having tea-time with her dolls and stuffed animals, Lucy was working on her dark poetry, Lisa was working on transforming water into the new fuel for cars, and Lily was being watched over by Mrs. Loud downstairs in the parents' bedroom.

As for Lynn and Lincoln, those two were chasing each other all over the house. None of them knew why, but Lynn really set Lincoln off and caused him to chase Lynn all over the place. Lynn was giggling like a little girl while running away from Lincoln, but Lincoln was catching up to her. While running down the hallway, Lynn used her parkour to bounce off the walls and leap over her sisters like an acrobat. However, despite using her acrobatics, Lincoln used parkour as well and was getting much closer to grabbing her.

Lynn rushed downstairs to the living room and leapt right over the couch, but Lincoln literally jumped all the way down to the first floor and hopped right over the couch and ended up standing right behind Lynn. Lynn shrieked and ran to the other end of the wooden table, using the table to block Lincoln from herself. When Lincoln ran to the left, Lynn ran to the left to avoid him. Then he ran to the right, but Lynn ran to the right as well, making circles all around the table. Both teenagers were huffing for breath, but they both were enjoying the chase.

"Take it back, Lynn! I do NOT watch 'My Little Pony: Friendship Is Magic'!" Lincoln said

"Oh yes, you do, Lincoln. Face it: YOU'RE A BRONY! CONFESS!" Lynn responded.

"I am not a brony! I never watched the show in my entire life!"

"Oh yeah? Then how come you have a 'BRONY' t-shirt in your closet?"

"That… that's just a gift from Ronnie-Anne! It was just a joke."

"Oh, yeah right. You even memorized all their names! You even asked mom if she can get you the My Little Pony toys-"

"OH, YOU'RE SO GONNA GET IT, LYNN!" Lincoln's back to chasing Lynn. While running away, Lynn was laughing hysterically at the thought of Lincoln having his own My Little Pony dolls. Lincoln was laughing as well as he felt his legs burn from chasing Lynn all over the Loud House. Suddenly, Lynn tripped on herself and crawled up to the sofa. Seeing Lynn defenseless, Lincoln laughed in a sinister way and began to slowly stalk to his prey. When Lincoln got onto the sofa, Lynn smiled to herself and grabbed a huge blanket laying on the sofa.

"Lincoln, you leave me no choice. I have to use my secret weapon…."

"Oh? And what would that be?"

"A DUTCH OVEN!" Lynn immediately wrapped the blanket around Lincoln and herself, completely covering the both of them making the blanket look like a cocoon. When they were both inside, Lincoln gulped nervously and held his breath. To Lincoln's surprise, Lynn put the palm of her hand on her mouth and blew really hard on it, making a huge farting noise. Lincoln looked at Lynn strangely, not fully understanding why she did that instead of actually farting. Lynn silently beckoned Lincoln to go along with the act. In a flash, Lincoln pretended to gag from Lynn's fake fart. Unable to contain herself, Lynn laughed hysterically. Even Lincoln laughed as well. When the two settle down and continued to stay hidden in the blanket, Lynn scooted closer to Lincoln and kissed him on the lips. Lincoln's eyes widen when he felt her soft moist lips caress his own. Lincoln succumbed to Lynn's very taste, closed his eyes, and embraced her. Lincoln slowly lied on top of Lynn and continued to share himself with his beloved as Lynn slowly dug her hands deep into Lincoln's pants and gently squeezed his ass. Lincoln licked Lynn's neck and started groping Lynn's developing tits, which made her let out a light moan.

Underneath the blanket, Lincoln and Lynn giggled as they continued to have fun with each other in the living room. Lana and Lola just stared at the huge blanket.

"Lana, what do you think Lincoln and Lynn are doing under the blanket?"

"Your guess is as good as mine, Lola."

"Let's go ask them."

"Good idea, Lola. HEY, LINCOLN! WHAT ARE YOU AND LYNN DOING?" Lana called out. The blanket suddenly ruffled nearly out of place. From the sound of it, it sounded as if Lincoln and Lynn were in a state of panic and fixing something underneath that blanket. Soon after they heard a zipper close all the way, Lincoln quickly popped his head out of the blanket."

"O-oh, hi girls! We-we're doing… NOTHING! NOTHING AT ALL!" Lincoln said, fixing his hair and tucking in his pants. When the blanket was starting to really come down, they saw Lynn fixing up her bra.

"T-there's nothing to see here, girls. We're just roughhousing, as usual!" Lynn said. The twins gave their elder siblings a suspicious look, trying to figure out why Lincoln and Lynn were blushing. Lincoln and Lynn started to feel a bead of sweat pour down their foreheads as they wore fake smiles to their little sisters.

"Yeah, you're right. Wrestling, as usual. Come on, Lana. Let's play outside!"

"Right behind ya, Lola! I hear the mud's really good at this time!"

"Ew, that's gross, Lana!" When Lana and Lola left the living room, Lincoln and Lynn let out a sigh of relief.

"Well, that was close. Hey, Lynn. Wanna check out what's on TV?"

"Sure, why not, Lincoln? I hear the life of Conor McGregor is on Fox Sports 1."

"SWEET! FS1, here we come!" Lincoln and Lynn flipped the TV set on and set the channel to Ch. 598, watching the documentary on one of the greatest mixed martial artists to ever live. As they started watching, Lincoln and Lynn wrapped the blanket around their bodies and secretly laced their fingers together. Feeling Lincoln's hand in Lynn's made her scoot closer to Lincoln and give Lincoln a quick smooch on the cheek.

What they didn't know was that Lori was watching them the whole time.

"Funny Business, Inc! Your fun is our business! A birthday party for your 5-year-old son, huh? No problem, Mrs. Anderson. Uh huh. Uh huh. Yeah, that address won't be hard to find. Sure, no sweat! Okay, see you this Saturday. You're welcome. Goodbye." Luan Loud hung up the phone and jot down yet another birthday party. Luan felt very blessed by how well her business is doing, getting seriously booked to do birthday parties and having over 50,000 subscribers to her comedic performances online. At this rate, perhaps Luan would make it big in the entertainment world. She also hoped that she could turn out just as awesome as her older sister, Luna. Luan and the rest of the family all know that Luna definitely has what it takes to make it big out there, judging from how highly talented she is in singing, song-writing and shredding the guitar. Who knows? Perhaps Luan will make it big out there as well.

Someone knocked at Luan's door.

"Who is it? I'm not busy right now."

"It's me, Lori. Can I come in?"

"Sure, hold on a sec." Luan opened the door and let her eldest sibling right in. Judging from the look on her face, Lori looked quite worried.

"Hey, what's the matter, Lori? You look as if someone just passed away."

"Luan… can you help me out?"

"Sure thing, Lori! What seems to be the trouble?"

"Well, it's about Lincoln and Lynn. Have you noticed anything strange between those two?"

"Not really. Lincoln has always been hanging around all of his sisters, so I don't see why fooling around with Lynn is any different than how he fools around with the rest of us." Luan's choice of words made Lori blush.

"… That's not the kind of 'fooling around' I was thinking about. Usually, we keep a scoreboard to see who Lincoln hangs around with the most. Luna was at the top of the chart since she seems to be the nicest to Lincoln and always had him help her with her music. But lately Lynn knocked Luna right off the top spot by a HUGE margin. Heck, Lynn has a higher score than ALL the girls combined!"

"… Yeah, you're right, Lori. Lincoln seems to be super-attached to Lynn over the last few weeks. Usually, Lincoln is just a laid-back kind of guy who doesn't really get into doing physical stuff. No sports, no exercising, none of it. Almost the polar opposite of Lynn. Now Lincoln seems to be nearly just as athletic as Lynn. That, and his body looks seriously ripped! He's going to be turning 12 soon, and yet he looks as muscular as those super-models on 'Men's Fitness' magazine! Did you see his abs? They look so-"

"Luan, enough with his physique! I… I don't really need such details," Lori said, blushing lightly.

"Oh… sorry about that, Lori," Luan said, blushing and laughing nervously.

"Lori, what really is worrying you?"

"Luan… do you think there's something going on between Lincoln and Lynn?"

"What do you mean?"

"I mean… do you think Lincoln and Lynn have some kind of… relationship?"

"What do you mean, Lori? Of course they're related. They're brother and sister, silly. What other relationship could they be having other than HOLY SHIT YOU MEAN THAT KIND OF RELATIONSHIP?!" Luan's eyes widen and her face blushed quite deeply from the very thought of Lincoln and Lynn having THAT kind of relationship. Lori looked away and blushed as well, but she tried to fight it off.

"Lori, that's crazy! Are you serious? There's no way Lincoln and Lynn would… be like that with each other! That's impossible!"

"Luan, you're the one who said all those nasty things about Lynn pulling down Lincoln's pants to do God-Knows-What."

"That was just a JOKE! I never thought they'd do that stuff for real! I… I can't believe Lincoln and Lynn would ever do that kind of stuff with each other."

"That's why I came to you, Luan. Luan… will you help me?"

"What would you have me do, Lori? Hehe, I sound like one of those characters from 'StarCraft II'. But seriously, how can I help?"

"I need you to spy on Lincoln and Lynn. I don't want to make any assumptions about those two. What I need is cold, hard evidence that there really is something going on between Lynn and Lincoln. You're really good at setting up cameras and recording people who don't suspect a thing. So can you please help me out? If what I think they're doing is true, this could hurt not only them but the entire family as well. Are you with me on this?" Lori asked. The very thought of Lynn even kissing Lincoln sent chills down Luan's body. Luan looked straight into Lori's eyes.

"You can count on me, sis. Lincoln isn't the only detective in the family!"

"Great! If we gather proof that Lincoln and Lynn are having a… relationship, we'll put an end to all this and we'll be a normal family again."

"… Have we ever been a normal family?" Luan asked.

"Touche', Luan," Lori responded. When Lori left Luan's room, Luan opened a case and took out her trusty video-cam.

"Lori, I hope you're wrong about this. I hope you're wrong about everything." When Luan held the video-cam and looked into it as if she was really recording something, she aimed it right at Lincoln's room.

"Look out, Ace Savvy. I, Little Ms. Juggles, is coming for ya!"
