In his bedroom, Lincoln lied belly-first on his bed, having four photos of his older sisters: Lori, Leni, Luna, and Luan. Each of his sisters smiled innocently to the camera, wearing their nicest dresses. Lori's and Leni's photos were from a wedding reception for his mother's best friend which was last year while Luna's and Luan's photos were from Lucy's birthday party a few months ago. All four of his sisters wore beautiful smiles to the camera, showing off their amazing beauty as if they were all supermodels.

Those girls were Lincoln's primary suspects who may be linked to the mysterious note that slipped right through his door and into his bedroom. Who could it be? Who could have known about his intimate relationship with Lynn? And the biggest question of all: who the hell wants to fuck him? Such questions made Lincoln blush out of embarrassment.

Lincoln eyed the first suspect's photo: Leni Loud. The fashion-guru and perhaps the most beautiful of all his sisters. Lincoln picked up Leni's photo where she winked to the camera and made quite a sexy pose. It may be highly likely that Leni could be the one who wrote that note to Lincoln. Besides, she was the one who confessed her feelings to Lincoln by giving him a big kiss the night of the Masquerade Ball a couple of weeks ago. Lincoln smiled to himself when he thought about that time she delivered that huge bombshell right to him. He remembered how delicious her lips were, how wonderful her large breasts felt when pressed against his body, and how succulent her scent truly was. Would it hurt to have a nice fling with Leni while keeping it hidden from Lynn? Perhaps not, Lincoln thought to himself. Then again, maybe he shouldn't. Betraying Lynn may not be a good idea.

"Damn, why did I have to hit puberty so damn early?" Lincoln though to himself.

Then he placed Leni's photo down on the bed's comforter and picked up the picture of Luan Loud. The comedian of the family. She may be the one who gave that note to Lincoln since she was known for placing hidden cameras around the house. Lincoln remembered one of Luan's April Fool's Day pranks he suffered from when he watched a video of himself and Clyde learning how to kiss a girl by using a balloon. He still felt a bit pissed off from that day not because of the prank itself but because his privacy was violated.

The young man looked to the bright side of Luan possibly being the culprit: if she did place a camera in his room to watch Lincoln and Lynn do the nasty, he felt he might have given Luan quite a good show. He wore a naughty grin when he imagined himself making hot love with Lynn while having the camera record all their hot love-making, and Luan would be their viewer. If she did record all their love-making, maybe she took all her clothes off and masturbated while watching Lincoln, butt-naked, bang the daylights out of Lynn. In a way, Lincoln strongly hoped it was really Luan who did it. After banging Lynn, he would bang Luan next! Luan may not be as voluptuous as Leni, but nevertheless she still does have a killer body. And how the hell can any boy resist Luan's laugh? Lincoln never admitted it, but he did find Luan's voice quite alluring. The thought of Luan making a move on him began to make his mouth water.

On to suspect number three. Lori. The eldest of the Loud siblings. Lincoln tried hard to think of a reason as to why Lori might be the one responsible for sending him the note. However, all he drew in his mind was nothing but a blank. There were times when Lori turned out to be a real meanie to her little brother, calling him 'twerp' every now and then. But lately, Lori did gradually change over the months, showing Lincoln love and respect as she did with all her other siblings. Not only that, but she already did have a boyfriend: Bobby. The chance of Lori being the culprit behind the note to Lincoln: nil to none.

And finally, there's Luna. The future rock-star of the Louds. Besides Leni, Luna was the kindest of all his older sisters. Lincoln loved how he hung around with Luna to either listen to many jams, make some rockin' attire for themselves, help Luna maintain or even play her musical instruments, or go to a certain concert. Luna was definitely his most favorite sister of all besides Lynn. To the only boy in the Loud family, Luna was a good friend and a kind-hearted angel. She was the most understanding and the most patient of his sisters. Luna was the only older sister who he felt that if she was the guilty culprit, everything he held dear about Luna would be ruined. Such beautiful innocence between the two should not be given the slightest wrinkle. Lincoln prayed to himself that she didn't send him that note.

"Oh, Lincoln! It's time to eat breakfast!" Mrs. Loud called out.

"Okay, mom. I'm coming." Lincoln quickly picked up all of his sisters' photos and placed them in his desk-drawer. Before Lincoln left his room to head downstairs and chow down, Lincoln closed his eyes and let out a big sigh. He mentally told himself to stay calm and act as if he never found the damn note. No point in getting edgy around his suspicious elder sisters. Just play it cool and act like it's just a normal day. After clearing his throat and giving his face a few good slaps, Lincoln started heading downstairs.

-:-:-

When Lincoln entered the kitchen in his pajamas, he saw all of his family preparing to eat breakfast. From oldest to youngest (with the exception of Lily), Lincoln's sisters lined up to receive a pancake, a sausage patty, and a hash brown from their mom.

"Good morning, everyone," Lincoln announced.

"Good morning, Lincoln," the entire family called back. When Lincoln picked up his plate, he went to the back of the line standing right behind Lisa, the Brainiac of the family.

"Sometimes, I wonder if it's really necessary to eat such things. All this breakfast is going to do is clog up our arteries and shorten our own lifespans. It wouldn't hurt to have a much healthier breakfast than what we're being served right now," Lisa said.

"It's okay, honey. We don't really eat all this that often. When you get the chance, you can give dad and myself suggestions for a healthier but still enjoyable breakfast, okay?" Mrs. Loud said.

"No problem, mom. I'll consider that a challenge, a challenge I proudly accept," Lisa said.

"I know what I clearly want as part of my breakfast: milk. Lots and lots of it…" Lynn said. The sports-jock looked back and gave Lincoln a nice wink. Lincoln clearly knew what kind of milk Lynn wanted, and it wasn't the one in the fridge. Lincoln looked away and blushed bright-red from Lynn's words. The young man was quite surprised that Lynn would make such a remark out in the open, especially in front of their own family! What if someone suspected her cryptic message to Lincoln?

When Lori got her breakfast and started heading to the table, Lana and Lola snickered to themselves when they were whispering to each other. When they eyed Lori, Leni, Luan, and Lynn, they started acting like a couple of braindead morons.

"Buuuh buh buh buh buuuuuuuhhhh…." Lana said.

"Buuuuuuuh buh buh buh buh buuuuuuhhhh…" Lola said back to her twin. Lucy covered her mouth and tried hard not to laugh, remembering their elder sisters' small accident last week. Even Lisa did her best to contain her laughter.

Lori, Leni, Luan, and Lynn blushed and wore very angry faces when their eyes darted at the twins.

"Knock it off…" Luan said through her grinding teeth.

"Buh buh BUUUHHHH?" Lucy asked.

"…. Buh…. BUUH BUH BUH BUH BUH!" Lisa added. Lana, Lola, Lucy, and Lisa laughed uncontrollably, remembering how their elder sisters crashed into a recycling can and how the eldest crashed into a tree.

"You girls are so dead meat!" Lori said.

"Uh-oh! The Buh Buh Buh Sisters are getting reaaallly angry!" Lola said.

"…. Girls, if you don't knock it off right now, I'm so gonna rearrange your-" Lynn's words were interrupted by Mr. Loud's loud whistle.

"Girls girls GIRLS! That's enough of that! We're about to have breakfast now. Save it for later after you eat AND digest your food. Understand?"

"Yes, dad," all the girls responded. The ruckus finally died down, but Lana and Lola were still quietly making fun of their elder siblings for crashing into things last week. Lincoln and Luna snickered a little when they remembered how they had to help their sisters get out of the can and help Lori regain her consciousness.

"Why the hell did that happen?" Lincoln asked, remembering that little incident.

"Your guess is as good as mine, dude," Luna responded.

-:-:-

It's been over an hour since Lola and Lana poked a little fun at their elder sisters, and ever since then Lana, Lola, Lucy and Lisa were being chased all over the house by Lori, Lynn and Luan. Lincoln was doing his best to enjoy one of his comic books as he lied on the floor of the living room, but all the ruckus going on in the house was starting to get a little bit on his nerves. At least Luna didn't have to worry about all the noise going on. Besides, jamming on her guitar in her room would obviously drown out all the roughhousing going on between her siblings. While Lynn was chasing Lana and Lola, Lori was going after Lucy and Luan was chasing after Lisa. As for Leni, she just sat comfortably on the sofa while reading her favorite fashion magazine.

"Hey, Leni. How come you're not chasing after those four?" Lincoln asked.

"It's no biggie, Lincoln. All is forgiven. Besides, I'm just not in the mood to work a sweat," Leni said.

"Hey, Leni. Can I ask you a question?" Lincoln asked.

"Sure, fire away, Linky," Leni said.

"Did you write me a –" Lincoln was interrupted when Lisa jumped right over Lincoln and ran off. Luan tried to jump over Lincoln but tripped over his body and fell to the floor.

"You okay, Luan?" Lincoln asked.

"Yeah, I'm fine. Lisa, GET BACK HERE!" Luan said.

"BUH BUH BUH BUH BUH BUH-"

"YOU ARE SO DEAD MEAT, LISA!" The chase ensued from there. Lincoln let out a sigh, not liking to be interrupted like that.

"So what were you going to ask me, Lincoln?" Leni asked.

"… it's nothing. No big deal, really." When Lincoln took a really good look at Leni, he noticed that Leni's breast-size was quite larger than Luan's, Luna's or even Lori's. Lori's breast-size was a C-cup, but Leni's turned out to be a D-cup! The only boy in the family even noticed that her dress was showing quite a good amount of cleavage. Lincoln quickly looked away and felt his face blush.

"Hey, Lincoln. I'm gonna head off to my room. If you want, you can help me by being a fashion model for my latest fashion designs. Would you like that?" The very thought of being in the same room with Leni began to make Lincoln's body heat up. Ever since that night Leni gave Lincoln a nice wet kiss, Lincoln couldn't see Leni the same way anymore. Lincoln used to see Leni as an innocent angel with a heart of gold. Now he sees Leni as a hot piece of ass that deserves a good fucking!

"Uh… I'll think about it, Leni." Lincoln said, doing his best to maintain his composure and not allow his sexual instincts to take over. Leni started heading upstairs to her room. The 16-year-old beauty started slowly going up the stairs, letting her hips shake to the left and to the right at every step.

"Well, if you change your mind, Lincoln, just let me kno-" When Leni turned around to look back downstairs, she caught Lincoln eyeing her in a strange way. Lincoln quickly looked away and blushed very deeply. Letting out a gasp, Leni laughed and tried to pull down the bottom of her skirt to hide her butt from his very eyes.

"L-L-Lincoln! Are you trying to look up my SKIRT?!" Leni asked, feeling her face blush.

"….no," Lincoln said very quietly.

"Uh Uh Uh! I CAUGHT you, Linky! You little pervert!" Leni said, shaking her finger right at him.

"I… I'm sorry. I didn't mean to do that, really. I was just… curious."

"Are you curious about what kind of underwear I was wearing? Or are you curious about whether or not I was wearing any undies at all?" That very question made Lincoln gasp in shock.

"N-n-NO! IT WASN'T LIKE THAT! REALLY!" No matter what he said, Lincoln knew that there was no way out of this. Leni immediately headed back downstairs, gently took Lincoln's hand with hers and had Lincoln head upstairs to her room.

"Come on, Linky. Maybe you'd like to take a closer look…" When Lincoln and Leni entered her room, Leni closed the door and slowly locked it. Leni wore a wicked grin when she eyed her little brother from top to bottom.

"Hey, Lincoln, let's play a game. It's called 'I'll Show You Mine If You Show Me Yours.' Would you like to play?" Leni asked. Lincoln's cock began to harden like stone and pointed right up to the ceiling.

"So… beautiful…" Lincoln's last shackles of restraint finally came off.

"… Sure. Why not… dear sister…" Lincoln stated. After months of containing her urges for Lincoln, Leni could finally let loose on her little brother and give in to her not-so-guilty pleasure. Leni unzipped the back of her dress and slowly let her dress drop to her ankles, revealing her white bras and g-string red panties. Smiling in a sly way, Lincoln slowly took off his shirt and tossed it to the wall. Eyeing his older sister hungrily, Lincoln unbuttoned and then unzipped his pants, letting his pants drop to the floor. Leni smiled and licked her lips when she eyed her younger brother from head to toe, silently admiring his amazing physique. What she really couldn't take her eyes away from was Lincoln's bulge in his underwear. The bulge was quite larger than what Leni expected.

"I'll go first, Linky…" Leni turned her back to Lincoln and slowly undid her bra. When she took her bra off and let them drop to the floor, she began to slowly pull down her red panties. Lincoln was amazed as to how incredibly curvy Leni's body truly was, being just as curvy as a red Cadillac. Her body was shaped very well like an hourglass, with silky legs and quite a nice juicy bubble-butt. As her panties dropped to her ankles, she took her left foot out of one hole of her panties and kicked it away with her right foot. When she faced Lincoln, she covered her breasts with one arm and covered her soft vagina with her left hand, teasing her little brother. Lincoln tried to keep his breathing under control.

"It's your turn, Linky. Show me the goods…" Blushing, Lincoln turned his back to Leni and slowly placed his thumbs on the edges of his underwear. As he slowly pushed his underwear down, Lincoln bent over and made his undies drop. Leni gasped and felt her body-heat began to rapidly rise when she watched how Lincoln exposed his naked butt to his own big sister. When Lincoln turned around, Lincoln covered his private part with his hands, feeling nervous about exposing his manhood to his older sister.

"Mmmmm yeah, that's what I'm talking about. You look really realllllly good to eat, Linky. How about you remove your hands from your salami and let your big sister get a good look?" Lincoln felt so embarrassed and looked away from his older sister.

"Well… okay, if you say so." Lincoln removed his hands and allowed Leni to set her eyes on his very manhood. Leni let out a gasp and covered her mouth in shock. Lincoln's eyes grew larger when he got a good look at Leni's large breasts and her pussy. Unlike Lynn's pussy, which was well-shaven, Leni kept her pussy nicely trimmed, made in the shape of a heart. As for her breasts, WOW! Her boobies were so huge she'd look good enough to get on Playboy or Penthouse magazine!

"Leni… you are so… incredibly… BEAUTIFUL!" Lincoln exclaimed.

"And you are by far the hottest boy I've ever seen," Leni responded seductively. Leni took Lincoln's hand and had him walk with her to her very bed. Leni then picked him up by the armpits and sat him on the edge of her bed. After making him eye-level with her, Leni leaned towards Lincoln and gently kissed him on the lips. Lincoln's heart pounded like crazy when he tasted Leni's soft lips and took in some of her saliva flowing into his mouth. Lincoln wrapped his arms around her sexy body as they continued to share each other through their very lips. Her body felt so soft and silky-smooth, quite softer than Lynn's muscular build. In a flash, Lincoln lifted Leni off the floor and tossed her right into bed.

"Wow, Lincoln! You're really strong!" Leni stated. When Leni lied in bed, awaiting her knight in shining armor, Lincoln towered over her and let his dickie aim at its primary target.

"My name is Chuck Norris, and I have begun the invasion of the Virgin Islands!" Lincoln announced. Leni couldn't help but burst with laughter.

"What?!" Leni asked. Lincoln closed his eyes and shook his head from saying something pretty stupid.

"Nevermind. I'll leave the jokes to Luan." Lincoln lied on top of Leni and placed his face onto her nice, large breasts. In a way, it felt awkward for Lincoln to be in bed with a much taller woman. He was use to making love with a girl who's the same height as he was, but now instead of being face-to-face with his lover, he was face-to-boobs with her. Then again, being shorter than his lover could have some advantages. He thought that while fucking her, he can easily stuff his face into her breasts and perhaps suck onto them. Not a bad idea, Lincoln thought to himself.

As he lied on top of Leni, Lincoln squeezed Leni's nice boobies lightly and then began to suck on one of her nipples. Leni closed her eyes and smiled as she enjoyed how wonderfully well Lincoln sucked on her nipples like a baby to a mother's breast. Leni brushed her hand through Lincoln's hair as he sucked and licked her boobs. Leni slowly wrapped one of her legs around Lincoln's waist, not wanting this to end.

"You're really good, Lincoln. Mmmmm yeah…" Leni whispered. Not wanting Lincoln to have all the fun, Leni picked Lincoln up and had him lie on his stomach. Leni gently lied on top of Lincoln's body, letting her boobs press nicely into Lincoln's back. Slowly, Leni let her boobs trace down Lincoln's back, which made Lincoln purr like a kitten.

"Hey, Lincoln. This is something I so want to do for a long time. Just lie on your belly and let me do the work. Okay?"

"Well… okay. Leni. Do your thing." Lincoln wondered what Leni was up to. After Leni slowly rubbed Lincoln's sides with her silky-smooth hands, the hot blonde slowly opened Lincoln's butt-cheeks and saw Lincoln's little butt-hole. Leni then stuffed her face into Lincoln's butt.

"Whoa, what the hell! What's going on back there?"

"There's someone knocking at the back door, Lincoln! And she's about to come in!" Leni opened her mouth and slowly stuck her sweet tongue into Lincoln's anus. Lincoln's eyes widen in total shock when he realized what the hell Leni was doing down there. Lincoln couldn't help but let out a high-pitch boyish scream when he felt Leni's tongue digging nicely into his anus.

"LENI! IT'S SO GOOD! IT'S SO FUCKING GOOD!" Lincoln screamed. Wanting more, Lincoln sat up and got on his hands and knees, making Leni get a better taste of Lincoln's ass. For a number of minutes, Lincoln moaned with delight as he felt Leni's lovely tongue dig nicely into his anus and sometimes even licking his balls. When Leni took her tongue out of Lincoln's anus and removed her face from Lincoln's butt, Lincoln collapsed to the side of the bed and panted for breath. Leni smiled as she watched how sweaty and in-heat Lincoln truly was from Leni's sexual advancement.

"Did you like it, Lincoln? Did you like it when I gave your nice butthole a nice licking?" Leni asked.

"…. Yes….oh yes…" Lincoln managed to say. Leni got on her hands and knees and aimed her nice big ass towards Lincoln when he sat up.

"Come on, Lincoln. Be a real bad-boy and give this girl a really good time!" Leni said. After catching his breath, Lincoln got on his knees and positioned himself into the doggie-style with his lover. Lincoln still couldn't believe how incredibly large and curvy Leni's ass truly was. As he placed one hand on her hip, he held his meat and aimed it right towards Leni's nice pussy. Lincoln tried his best not to worry about getting Leni pregnant. Such thoughts might only ruin the experience. With one big breath, Lincoln slowly plunged his big cock right into his older sister from behind. Leni whipped her head back and let out a huge scream when she felt Lincoln's cock finally enter.

"AAAAAAAAAAHHHH! HOLY SHIT, LINCOLN! IT'S AMAZING! IT'S SO DAMN AMAZING!" Leni screamed. Keeping his breathing under control, Lincoln began to thrust into his older sister like a piston. Both Lincoln and Leni took in the wonderful experience of truly being what it's like to be as one for the very first time. For over ten minutes, Lincoln thrusted into his 16-year-old sister, watching his big cock go in and out, in and out, of Leni. Unable to contain herself, Leni screamed uncontrollably from the delight of having her little brother bang into her hot pussy, letting her tongue hang out while letting Lincoln bang away at her.

When Lincoln took his dick out, Leni lied on her back and spread her legs really, REALLY wide. Lincoln was amazed from Leni's flexibility.

"Have more of my American Pie, Lincoln! COME AND GET IT!" Leni screamed, sounding as if she was serving some barbeque. Feeling the animal from within roaring, Lincoln dove right on top of Leni and plunged his dick right inside her. Lincoln thrusted into Leni harder and faster than the last time. Leni kept her legs spreading out as she moaned and screamed from Lincoln's onslaught. Yearning to fill Leni up really good, Lincoln nicely squeezed Leni's large breasts together and licked her breasts and nipples hungrily as he continued to thrust away into Leni's sex-chamber. Both Lincoln and Leni were covered with a lot of sweat. In a way, both of them felt that hot wet sex is one of the best ways to get a really good workout!

"Oh my freaking gosh, Lincoln! Lynn's right: you really are an animal!"

"… What did you just say?"

"I-I said you're a freaking animal! Fuck me harder! FUCK ME!" After many minutes of banging the daylights out of Leni, a beautiful sensation rushed through both of the lovers, making their screaming amplified by 10.

"Leni! Leni, I think I'm going to cum! I need to take it out!"

"It's okay, Lincoln. You can cum inside of me. I already completed my menstrual cycle, so feel free to fill me up good!"

"Are you sure, Leni?"

"Trust me, Lincoln! I won't get pregnant, I promise. Oh, shit! OH, SHIT, I think I'm going to cum, too!

"Oh, no! Oh, no! I can't hold it in any longer! I'm gonna cum!"

"Go ahead, Lincoln! Do it! I want you to fill me up with your hot, creamy milk! Uh oh! I'm cumming! I'M CUMMING!"

"I'M GONNA CUM! I'M GONNA FUCKING CUUMMM!"

"FILL ME UP, LINCOLN! OH, YES! YES! YEEEEESSSSSSSSSSSS!" Lincoln and Leni screamed in unison as Lincoln came inside his older sister. Leni screamed with delight as she felt Lincoln's hot milk fill her up. After taking in a few deep breaths, Lincoln finally took his dick out of Leni's pussy and laid tired as heck next to Leni.

"Wow. Just… wow. You fuck like a real pro, Lincoln."

"Glad to be of service, Leni." Leni and Lincoln embraced each other and gave each other a beautiful kiss. When their lips finally parted, Lincoln and Leni embraced one another and let their sweat mingle together.

"Hey, Leni."

"Yes, my dear Lincoln?"

Lincoln whipped out a note he found nearly a week ago. It was the very same note Lincoln found in his bedroom, the one with the heart on it.

"You wanted to know how much of a sex-machine I can really be, and I'm glad I lived up to your expectations, Leni. It makes me happy to know that I can make you happy, ya sexy thing. You have a very kinky way of coming onto me with this note you wrote," Lincoln said. Leni only looked at Lincoln with a confused face.

"Lincoln, what are you talking about? I didn't write that." Lincoln eyed Leni strangely.

"… You didn't write this? At all?"

"No, of course not." A terrible thought crept into Lincoln's mind.

"… I fucked the wrong sister! NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO-"

Lincoln was suddenly interrupted by Leni's lovely lips on his own. The delicious taste of Leni removed such thoughts from Lincoln and he instead kissed her back passionately.

"… Oh well. First Lynn, now Leni. The more, the merrier! Aw yeah…" Lincoln said to himself. As he and Leni rolled all over the bed and kissed away, Lincoln mentally removed Leni from the list and deemed her as 'innocent.' One girl down. Three more to go. Does that mean he has to fuck his way to the truth? If so, this would be Lincoln's best days of his life.

A/N Hey, wassup you guys. The name is Bleeding Wings. Nice to meet ya. I want to thank all my readers for giving me full support for my Loud House story. At first, I only wanted to strictly stick to Lincoln and Lynn being a couple. However, at the last-minute of editing Chapter 10, I decided to throw Leni in as well. It just seemed like the right thing to do, and it sounds more fun than just having Lincoln stick to one girl. Of course, I'm not going to make this story last forever. The story's just a few more chapters away from coming to an end. Besides, I need to dedicate my time to writing original stories instead of strictly sticking to fanfics. And when my story ends, let's just say that it'll end with a BANG! Well, it's time for me to brainstorm what will happen in the next chapter. See you guys in a bit! And again: thank you all!
