A/N: Hey there people, Skylar here with chapter 3 of 'A Big Sister's Job'. I would like to say thank you to all the reviewers for helping me out with things I need to change to make the future chapters better. I'd also like to thank all the people who followed or favorited this story. It really means a lot to me! Just a heads up, this one's gonna be a long-ass one.

Dread55: Thank you for your input friend, I'll try my best. Btw, I love the idea about Ronnie and LJ being together. Maybe, I can make a spin-off or something..

Shaeril McBrown: Umm..Shaeril, his heart's already broken and he already found out about Chandler in Chapter 1.

Smiling Lemon: Thanks, it was really helpfulJ

Delquea: I'm telling you here, Bobby's gonna be really dumb in this story. So, who knows..It's all for letting Lori and Lincoln be a much more stable couple (Again, I'm deeply sorry to all the Bobby Santiago fans)

nuuo: Come on buddy, 'Birds of Prey' was life changing for a 14 year old girl like me! I don't agree with the opinion that most people haven't seen the movie. I mean, Sonic was great too but…it's cool, you have the right to be entitled to your opinions. I'm sorry if I sounded mean, it was not my intent. We cool rt?

Kirby: Totally! I named him after Raj. Man, I miss TBBT!

364wii: I think he didn't blow a load on her, it was all precum and stuff..

GeoSoul: Thanks!

Crisis Nova: Thank you for your advice. I'll look into the problems and I really appreciate your helpJ Now about Stella, although there's no place for her in the future chapters, here's a small backstory (Coz she's one of my fav characters from the show and deserves justice from my side) - She liked Lincoln but Lincoln didn't get the signals. When he started dating RA, she felt angry and betrayed and all she ever wanted to do was hurt Lincoln. As for the other friends, they are just jealous of Lincoln for having something which they don't.

OzzyOzborne: I totally agree! I'm not a huge fan of how I finished the last chapter. I tried my best with the ending of chapter 3 and thanks for your support!

Chapter 3: A Forbidden Relationship Begins

The next morning, Lincoln woke up to find Lori sitting at the far end of his bed, thinking about something deeply. He thought "What's Lori doing in my room?" Then he remembered the events of last night. He remembered his weird dreams and how he broke his sister's trust by dry humping her without even a little bit of shame! He felt like he deserved to rot in hell for his pervy acts.

He looked at her with heavy lidded eyes, pretending to be still asleep. She was in her blue nightgown, underneath which she wasn't wearing anything, he found that out the hard way. He remembered the position he was in last night, with his dick pressed against her…that instantly made him pop a boner. He felt so disgusted with himself! He pressed his legs close together to hide his erection and imagined how his family would disown him for being a freak.

He started to panic internally, thinking if she was waiting for him to wake up to confront him about last night. What if she told mom or dad? That would get him in big trouble! But then again, he heard her moan his name in her sleep. What if that meant she was facing the same problems as well? What if her kisses were not as sisterly as he previously thought them to be? The possibilities were infinite and all of them terrified the shit out of him.

At that moment, Lori shook his 'sleeping' form gently and said in a soft voice "Wake up sleepyhead, it's 9am already". That gave him some confidence. She said that in a manner as if she didn't know anything that happened, the night before.

Lincoln faked being tired and begged "5 more minutes, Lori.." He thought maybe that would get her off his back and the things that occurred would be something that happened a long time ago, which they don't talk about at all. He hoped she would allow it and just leave.

Poor Lincoln, that wasn't the case! Lori deeply inhaled and replied in a shaky tone "Alright…I didn't wanna say this, but here it goes- Lincoln, I literally know, you know what happened between us last night. I just…"

She was cut off by Lincoln, who instantly sat up on the bed and said "You do? Oh my god, you must think I'm such a pervert! I'm so sorry, Lori. I promise, it won't ever happen again. Just don't tell mom and dad, please!" He said a last part with a lot of vulnerability, with tears fogging his blue eyes.

Lori's heart melted at her brother's breakdown. She replied in an apologizing tone "No, I'm sorry Linc. I am..well…let's just say, I was the one who literally started it. I raped you! I'm sorry for being such a pervert. You didn't do anything. Please forgive me. I swear I'd drop all my feelings for you"

Lincoln raised an eyebrow and asked "You..you have feelings for me?"

Lori just looked away and tried to avoid the question. Lincoln's theory was correct, she did feel something. All the things she said in her sleep were indeed what he suspected them to be about.

He asked in a shaky tone "How long?"

Lori answered in a shameful tone "Ever since I saw how deeply you cared for me, even after all the bad shit I did to you. I mean, it's that I trust you to never hurt me unlike Bobby who doesn't give a shit about my feelings"

Lincoln held her hand and said "If it helps, I too have had some weird feelings about you Lori. So, don't think of yourself as the only one to blame here. You didn't rape me. You could never do that to me"

Lori looked at him in surprise and asked "So, in your sleep, while you were humping me, you weren't actually thinking about some other girl? You were thinking about me?"

Lincoln shamefully nodded and looked down. Lori's eyes went wide with disbelief.

She ran her hands over his smooth dyed blonde hair and asked "How did that feel? I mean, in your dreams.."

Lincoln rested his head on his sister's shoulder, with a bit of caution and replied "Although, I had weird dreams about people calling me a freak and hurting me for crushing on you, it just felt right. It's..it just..I never felt so comfy in anybody else's arms than yours. Lori, you made me feel so much better and vowed to be there for me no matter what. And that peck on the lips, really made me think of you differently. I know it's stupid"

Lori replied "It's not stupid baby bro. I know us loving each other is something called doomed by our society, but if we like each other more than anyone or anything then who are we kidding? I am gonna answer for myself here…it just felt literally right to feel your bare flesh against mine"

Lincoln looked at her like he has seen a ghost. All that meant her beautiful sister thought he was attractive too. He snapped out of his trance and asked in a shaky tone "So, what's gonna happen now? What do we do?"

Lori answered in a braver voice "Probably give our relationship a try, for the best"

An unconvinced Lincoln asked her with worry in his eyes "But what about the others? What if they find out about us? We won't be able to live our normal lives, ever"

Lori answered with that same unshaken voice "Then, I'll protect you. Moreover, we don't have to like, tell anyone. We just gotta be real careful of our actions and wait for our family members to not be there during our more 'intimate' moments"

Lincoln felt a lot better hearing that. He hugged his sister (lover?) tightly, melting into her warm embrace. They stayed like that for quite some time before Lori said "Okay, it's literally 9:35 am, we gotta get outta here before they finish all our food". Lincoln nodded and they both left to get ready for a pleasant Saturday.

The day went fine for both of them with Lori spending most of her time at the mall with her friends who comforted her and agreed with how Bobby was just spineless and was his sister's puppet. They said she deserved better. All that support from her girl-friends melted her heart. She thought what did she ever do to deserve friends like them? She just wished Lincoln's friends were as supportive as hers when Ronnie Anne stomped on his heart and broke it into a million pieces. Those bastards!

Back at home, she was requested by her mom to talk to Lynn about how hurtful her behavior can be to other people. That attempt was a futile one. God, that girl knows how to get on Lori's nerves! She also talked to Leni, advising her how to make things right with Lincoln. Leni listened with great attention and hugged her in the end, for being so nice to her. Lori just giggled at her sister's child-like behavior.

Still, she had one person in mind, like all the time and he was her little brother who she loved so much! Thinking about last night just made her feel so great. And the fact that he liked her in a deeper way, gave her so much warmth. She wanted to talk about her feelings about Lincoln with Leni, but she knows it would be like suicide. With nothing to do at home, she just wondered if he was having fun with his good friends or not?

Last night, Girl Jordan and Clyde had secretly planned to make the day awesome for Lincoln by buying tickets for the new Ace Savvy movie. Lincoln had the time of his life watching the movie with two friends who deeply cared for him. He could also see Clyde and Jordan acting awkward around each other, like he behaved infront of Lori. He smiled and told them they would look cute together. Both of them pretended like they didn't know what he was talking about, making it even awkward, much to Lincoln's amusement. After the movie, they spent most of the day at Jordan's house/mansion, playing video games and eating junk food. Although, Jordan wanted it to be a sleepover, she had to be there for the party for her dad's blah,blah,blah… tonight.

It was 5:37pm now and Lincoln and Clyde were on their way back home. Clyde asked "Don't you think we should spend more time at Jordan's?"

Lincoln answered with a smirk "Yeah we do, she's such a good friend. Both of you are. And the house, I didn't know Jordan was Bruce Wayne rich!"

Clyde replied with a smile "I know right! And she's like an angel…her honey blonde hair shines so brightly in the…" and started to drool.

"Okay, that's enough drooling for the day. But congratulations, you like Jordan…and trust me, she likes you! You guys should totally date buddy. That way everybody wins!" said a happy Lincoln.

Clyde just looked at his friend with hopefulness, but his expression turned into worry in a few minutes. Worried about his friend, Lincoln stopped for a moment and asked "You okay Clyde? You look a bit.."

Clyde answered in a shaky tone "What about Lori? That pussy Bobby broke up with her yesterday. I think she needs me more than Jordan. I love her Linc, I can't be with Jordan!"

Lincoln, although angry at Clyde, assured him calmly "Don't worry, she's happy. She's even found a new guy who understands and likes her. She has known that guy ever since he was born. Even I like that dude"

Clyde said in a crushed and confused tone "Another..guy?"

Lincoln started walking and replied with a normal voice "Yes Clyde. See, Lori's much, much older than you. She likes you, but more in a little brother way than a lover way. Try to understand. Jordan's a much better match for ya"

Clyde nodded and thanked him for opening his eyes for the millionth time. Lincoln was happy that he didn't end up punching Clyde for being in love with Lori. That would have been messy and unnecessary.

Both friends parted ways outside Lincoln's house, with Lincoln agreeing to help Clyde approach Jordan and tell her how he feels at school on Monday.

Standing on the front porch of the Loud House, it indeed sounded Loud. Lincoln walked inside to find 9 pairs of eyes (All sisters except the grounded ones and Rita and Lynn Sr.) on him, asking him a thousand questions. He had gotten used to it over the years. Asking them to calm down, he explained how he had the time of his life with his real friends.

Everyone felt so happy for him. Lynn Sr. had prepared Lincoln's favorite dish with a collaboration with Rita and Luna for a huge chocolate cake for dessert. Lincoln couldn't have been more grateful towards his family for their support. He was super-touched to see that Lily had made a comic about a 'super-hero' brother who protects his family and the world from super villains. God, he loved that sweet girl! He talked with Lana, Luna and Lily about the movie and felt really glad they listened without blowing raspberries at him or asking him to stop talking like a nerd (Not that the three of them have ever done that, but he was damn sure that Lola, Luan and Lynn would). It felt like everything was back to normal.

Well, that was before bed time when a new realization hit him like a train- he hasn't talked to Lori for a second after coming back home! That made him feel really bad and he felt like as if somebody was squeezing his insides really hard. Lying on his bed in his dimly lit room with everyone else asleep, he wondered what being with Lori would be like. She's much more experienced, unlike Ronnie who was a big baby about everything. He just wanted to kiss her, to feel her skin against him, to…he sighed exhaustedly. He wondered if he had gotten crazy. He knew loving his sister like that is super wrong. Still, Lori wasn't worried. How could she be so cool about it? Or was she being brave for him?

Although nobody would ever support their relationship, he knew he loved her and she loved him. Moreover, it isn't as if they were random people who felt something for each other, they were family, quite literally! He knew neither of them would ever hurt each other. Why can't loving your sister be normal them? He felt like something was wrong with this society, not them. Then again, he felt like he screwed up with Lori after unknowingly 'ignoring' her. What if she was mad at him right now?

His deep thoughts were interrupted by a soft knock on his door. Without even looking, he said in a plain tone "Come in" Lori entered his room with her pillow, wearing that same night gown that brought bitter-sweet memories in his mind. She said "I asked mom. I can sleep here until Leni's new designs are finished. Good news, ain't it?" He could see her nipples poke through the light blue silk and blushed furiously. Locking the door, she asked in an 'innocent' tone "You okay buddy? You look a bit red there.."

Lincoln answered in a shaky tone "I'm okay. Just thinking about us…"

Lori walked up to his bed with a cute smirk and said "Okay, that's literally sweet!"

Lincoln asked her "Why aren't you seeing how wrong this is? I mean, you're just so cool about it. How are you doing it..I mean, handling the guilt of…this?"

Lori sat down on the bed and answered softly "I just don't think about it too much. I know I love you and that's the only thing that matters to me". Lincoln's eyes welled up with tears upon hearing that. Lori gently wiped them and said in a sweet voice "You're my world baby and nobody can take you from me". Lincoln smiled and said "Thanks, I needed to hear that"

She just pulled him close towards her and kissed him passionately on the lips. Although it was uncalled for, Lincoln returned it with the same energy. It was their first real kiss as a couple. A few moments later, Lori who broke it and asked shyly "So, how did it feel?"

"It felt awesome! I never felt that spark before when I kissed Ronnie" Lincoln answered with a huge smile. He put his hands on Lori's hips and initiated another kiss. This time, both of them were a bit more aggressive with their tongues battling for dominance. Eventually, Lori being the experienced one came out on top and left Lincoln panting for air. Lori couldn't help but chuckle at her brother's expression.

With a mock angry expression, Lincoln used all his strength to push his sister on the bed and got on top of her. Lori yelped at her brother's aggression. He started kissing her neck and moaned at the softness of her skin. Lori loved each and every moment of it. Lincoln's hands roamed towards her chest. He cupped her breasts and felt the softness of them through the silk. His eyes went wide with disbelief, he didn't know boobies felt this soft! Lori laughed at his expression and asked "Like these gals?" Lincoln dumbly nodded.

Smiling again, she moved her brother's hands away from her breasts and flipped their positions, so that she was on top this time. Lori removed her brother's shirt and threw it on the floor. Lincoln, now only in his boxers, looked at her with uncertainty. But all that changed when she started massaging his arousal through his underwear. He groaned and begged her to do something. Still massaging his dick, she kept covering his hairless body with kisses until she reached down to his pelvis.

Smirking at him, she hooked her thumbs into the band of his underwear and pulled them down to his ankles. His dick immediately slapped her on the face with a meaty thwack. It was big for a boy, his age. Lori looked at her brother's embarrassed face with a chuckle and assured him "Don't worry, big sis's gonna take great care of you"

She grabbed his dick softly with her hands and started licking the head, painfully slowly, ignoring the pubic hair giving a tingling feeling to her nose. Lincoln felt like he was in heaven and hell at the same time. His sister's tongue did wonders to him. But this was nothing compared to what's coming next. Lori engulfed his dick slowly, inch by inch and started blowing him. Lincoln loved the moist feeling of his sister's mouth and started thrusting slowly. By the look of it, Lori's done this before. She moved her mouth up and down on his dick and occasionally licked his cock head. This was so much better than masturbating! His face turned a deep shade of red with so much pleasure. After some time, he felt like he was losing it! He grabbed Lori's head and started thrusting faster and faster into her mouth. His dick started tingling her throat with the new energetic thrusting. Lori kinda liked her brother's aggressiveness and overthrew the urge to puke. That would be messy!

A few moments later, Lincoln warned "Lori…gonna..explo…move awa…." But, Lori looked at her brother's face and gave him a thumbs up. Lost in pleasure, Lincoln blew his load into his sister's mouth, with his eyes rolling back into his head. Lori swallowed all his cum and swirled her tongue around to clean his cockhead. Calming down from his orgasm, Lincoln felt embarrassed at his work on her mouth and nervously chuckled.

Lori asked him with a smirk "What you laughing there for, slugger?"

"Nothing, now lay down..lemme show you what kind of a sweet little brother I am" said Lincoln and sat up on the bed.

Lori complied and laid down on the bed with her legs positioned in an M shape. Lincoln got in his knees between her legs and hiked her gown up to her waist. He stared at the new sight infront of him with wide eyes. Lori said with a worried tone "Look, if you wanna back away, it's okay. I know you're too young for this. You don't have to do this if you don't want to"

Lincoln answered "No, I'm ready Lori! For you, I am!" and took a good look at what was infront of him. She was well shaven down there and her clitoris looked all cute and swollen. He just felt so hungry for Lori's pie. The musky smell from her nether regions that filled his nostrils up turned him on so damn much! He started planting kisses in her lower lips and her clit. Lori shuddered at that. Looking at her excitedly, Lincoln started playing with her clit and licked and sucked on it a few times. Lori liked her brother's work down there and squeaked in joy, covering her mouth with her hands to muffle her moans.

Lincoln inserted his middle finger into his sister's boiling hot centre and felt the warmth and tightness of it. He amateurishly started moving it in and out of her, with some resistance from her incredibly tight centre. To his surprise, Lori seemed to enjoy it and put a pillow over her face to stifle her moans. After some time of doing so, he removed his finger, soaking wet from her juices.

Lori whined and asked him "Why did you stop? You were doing so.." Lincoln immediately plunged his tongue inside her pussy and started eating her up. Her hole tightened around his tongue in arousal. She felt so great right now! How was he doing this? Bobby was never this good. Maybe, Lincoln was a natural like their father. Lori rested her legs on Lincoln's shoulders and squealed and moaned with delight as he kept eating her up like a hobo who hasn't eaten for 20 days.

With a little more tongue magic, Lori squirted all over her brother's face with a muffled cry of joy. Removing the pillow from her face, she saw her brother with an angry pout in his face, saying "Now I smell fishy! A little heads up would have been nice!"

Lori laughed hard and asked "You ready for the main event, hothead?"

That made Lincoln's anger dissipate. He got on top of her and kissed her on the lips once again. He tore her night gown open and threw it on the floor. An angry Lori protested "Hey! What gives? That was my favo.." to be cut off by Lincoln, wrapping his mouth on her left boob and sucking on it, hard. Lori moaned in ecstacy. Her brother's lips felt so soft around her globes. Lincoln moved his attention to her right boob and circled his tongue around the nipple a few times. Lori's face was beet red with pleasure. She begged in a desperate voice "Please fuck me, Lincoln! I need you..please"

Seeing the despair in her voice, Lincoln took a deep breath and asked "You're not a virgin, right sis?"

Lori answered in a worried tone "I'm sorry Linc, I've fooled around with Bobby a few times" Hearing this, Lincoln wanted to beat Bobby up with a sledge hammer. Lori assured him "Look Lincy, atleast you get to get your first time with your true love. Turns out, I didn't! But, you have the opportunity now. And you gave me an orgasm thousand times better than what Bobby has ever given me. So.."

Lincoln smiled brightly at her kind words and said "Okay, I'm ready!"

He looked into his sister's ocean eyes and lined his member with her vagina. He said "You have beautiful eyes Lori"

Lori said with a smirk "You have the same eyes silly! Now please, I need you inside me!"

Lincoln kissed her on the lips and obliged. He pushed slowly inside his sister. Lori cried out loud into her brother's mouth and grabbed the bed sheets tightly. Her walls tightened around him. It was the best feeling in his entire life! He felt like he was gonna cum right then. Cooling down, he started moving weakly inside her. When she signaled him, he started to bang her with deep thrusts. Lori loved the way her brother was doing her. Soon, he moved Lori's legs on his shoulders and tore into her.

Lori kept squealing in delight. The new position did wonders for both of them with Lincoln hitting her spot quite easily with each thrust. Echoes of flesh slapping on flesh could be heard inside the room. But with the pleasure both were getting, neither cared for a little bit of logic. Lincoln fucked Lori like a common slut with Lori giving him encouraging words "Yes! Harder baby! Yea…that's it! Right there!"

Lori's legs felt weak with her brother constantly hitting the right place inside her. Grabbing her smooth legs as leverage, he went even faster. He loved the way Lori's boobs jiggled with each thrust. He had never seen her in this light. She looked damn beautiful with him dominating her.

After fucking like that for a few minutes, Lincoln warned "Lori, I'm..I'm clo..close"

Lori encouraged him "Do it Linc! I'm..on the piiiiiiiiii" and released her juices all over Lincoln's dick with a sharp cry. Lincoln continued with his thrusting until he came inside her with a tired groan. Her pussy milked his cock from every little bit of semen he could possibly give.

Both of them laid side by side, naked, glistening with sweat, panting for air. Lincoln asked "So, was I good?"

Lori purred in a satisfied tone "Yeah you were! One day you say you are not ready for sex and the next day, you fuck me better than anyone in my life! You are a natural, bro!"

Lincoln blushed at the compliment and asked "I'm getting hard sis! Wanna go for round 2?"

Lori just couldn't believe what was happening! Life was gonna be so great for her- both with the lovey-dovey stuff and the sexual ones! What was up with Lincoln's stamina?

Once again, Lincoln got on top of her and entered her with a swift thrust. This time, both knew what to do. Lori wrapped her arms around his neck and her legs around his waist. Lincoln kissed her on the lips and started thrusting into her passionately. It was so intense for both of them. Lincoln kept hitting that spot inside her that made her squeal in delight. His balls slapped hard into her soft butt and left red marks. Lori still couldn't process how he was doing this! He was just 13 and a half for god's sakes!

In a few minutes, both decided to try a new position with Lori going on top now, moving up and down on Lincoln's dick, slowly. Lincoln's hands were on her hips, feeling the softness of her skin. He looked tiny compared to her. She brought her mouth down to kiss Lincoln on the lips. Both of them moaned in pleasure.

Lori decided to have some fun by burying her brother's face with her huge globes. "Ngggggg..these are some big ol titties sis!" Lincoln said with a muffled voice. He deeply enjoyed being buried under his sister's boobs and started sucking on them softly. Lori liked each and every bit of it and kept gyrating her hips lustfully!

Now, a 'buried' Lincoln started to match her thrusts with some of his own. Lori squealed in pleasure. It took some time for both of them to match each other's rhythm. Now, Lori was bouncing hard (not too hard) on Lincoln's dick with the bed creaking. Thank god the parents decided to makes all rooms soundproof, last year! Lincoln squeezed her butt and played with them like dough. Lori enjoyed her brother's soft hands on her ass and encouraged him to go on.

With a few more bounces, Lori once again squirted on her brother's dick. Lincoln threw Lori, drunk with pleasure on his bed and sat on her face, grinding softly. Lori took him in her mouth and Lincoln came for the third and final time that night, this time all over her face. Both laid down, panting for air.

"Good night Lincy!" said a tired Lori and yawned.

"Good night my lovely big sis!" said Lincoln and kissed her again. Both slept much better that night with Lori spooning Lincoln and keeping him warm. Lincoln felt the safest he's ever felt in his entire 13 years of existence and absolutely loved his sister's touch. Lori felt like she found a new purpose in life and that is to take care of her bother/lover. What they didn't know was both of them were thinking about the same thing - trying to find some excuses to get the next week all to themselves for you know what ;)

A/N: That's it for chapter 3! What do you guys think? Pls tell me if I'm wasting a lot of time building up to these thingies? I mean, I feel like I wrote too many unimportant things here. Just be honest guys, there won't be any hard feelings, trust me! & can u guys suggest some ways to have Lincoln and Lori have the house all to themselves for the next week? How about the whole family goes to Lisa's science conference in California, all except Lincoln and Lori, who decide to stay back at home for 'please tell me why guys! I can't think of a good reason!'? Anywho, I'll see you guys in the next chapter!
