Chapter 2

Heavy breathing echoed throughout the room. Lincoln thrust his hips as sweat fell from his brow. his gaze was entirely on Lynn, feeling her embrace as his dick was encased inside her. it was warm, and he wanted to keep going, despite his inhibitions. Lynn leaned forward and planted a kiss on his lips. Her face being just was sweaty as her partner's, albeit more from Lincoln's face.

"How do you like it? Does it feel good?" she said, panting.

Lincoln nodded. "y-yeah. It's feels so good." He cupped her breasts and sucked on them. He received another moan from Lynn.

Lincoln thrust his hips faster. He could feel his sister tightening in. he wanted to pull out, but Lynn wouldn't let him, wrapping her arms and legs around and retraining him.

"L-Lynn! Please! I'm going to cum!" Lincoln murmured. His eyes widening as he began to panic. He was bareback and such a position was a potential hazard.

A devilish grin appeared as Lynn shook her head. "uh-uh. Lincoln. I want you to let it all out and that means every drop." Lynn had gone mad.

Lincoln tried to break away, but Lynn's grip was too strong. It was too late. Lincoln thrust for the last time. he led out a bellowing roar as he climaxed. His seed pumping by the gallons. His sister released him, and he rolled to the other side. A look of horror plastered on his face. he wanted to get up and discuss Lynn about what had just transpired but his vision started to blur. The last thing he saw was Lynn leaning over him. she smiled as she told him: "You were amazing, Linc. Let's try this again sometime." She leaned in with her lips kissing his.

That was all that he remembered.

The sun rose, and Lincoln's eyes fluttered open. Turning to his clock, he saw that it was 6AM. Class did not start for about two hours. He groaned as he placed a hand to his forehead.Oh god. That was the most bizarre dream I have ever had.However, when he leaned up, his eyes widened as he noticed an arm on his chest. He followed and saw that it belonged to Lynn, sleeping peacefully while lying naked under his sheets.

His body shook nervously. His face falling as it wrinkled. Oh, no! it wasn't a dream!His memories of the night before started flooding back. He was trying to comprehend. His hands clenching the sides of his heads. He could feel his chest becoming heavier as if a heart attack was about to occur. He thought he was still dreaming but the feeling of being drained and the soreness of his genitals stated otherwise. I just fucked my sister. What the hell came over me? None of it made any sense. How could he have allowed himself to fall into such sin? Was he just tired, or was he did he want it?

Suddenly, his sheet began to rustle as a gentle moan was heard. he turned and saw Lynn waking up. She grinned as she crawled up to him. "Good morning, lover~. How did you sleep last night~?"

"J-just fine. I s-slept like a log," he said, nervously.

Lynn's smile faded as she arched her brow. "Lincoln? Is…something wrong? You look distressed."

Taking a deep breath, Lincoln finally spoke what was on his mind. "Lynn. you are my sister. We just had sex. Worst of all, I just came inside of you without wearing protection. I mean, what would happen if I knocked you up? How are we going to explain this to everyone?" His tone was becoming more aggressive as he flashed a glare at his older sister.

Lincoln was under a lot of pressure. All these thoughts coursing through his head. However, his trepidation ended when he saw the state Lynn was in. she frowned as tears started falling from her eyes. it was a rare sight to see her crying as Lynn was known for her toughness and tomboyish nature in the Loud family. The sight of her shedding tears was alien to Lincoln.

"You know what? you're absolutely right. we shouldn't have done this from the beginning." Lynn got up off the bed and started picking up her clothes. She put her clothes on as fast as she could, but she just kept muttering. "What the hell was I even thinking. Just forget any of this ever happen and let's just go back to the way things were." Lincoln watch Lynn storming out of his room but not before receiving the final emotional blow. His sister turned back. Tears flowing down her cheek.

"See ya, Linc. Hope you have a good day."

That struck a blow to the young man. A tinge of guilt erupted in his heart. The one thing Lincoln hated was upsetting his sisters, even if he called them out for something that was either wrong or questionable, which is something they don't want to be reminded of. Getting out of bed, Lincoln sat at the edge with his hands planted on his face. his gaze beaming at the poster of Ace Savvy that hung in front of him. what was he going to do? He wasn't strong enough to stop Lynn, both before and after the deed was done. He didn't even have the courage to talk to her about it. Although Lynn said that everything was going to go back to normal, he doubted that such a thing was possible.

All four of them were sitting in the kitchen. The dining room table just being a small and round outside table with four lawn chairs. Under their budget, it was the cheapest thing the louds could afford. Also, Leni thought it was just fun to own. Lincoln had made himself and his sisters a standard breakfast, consisting of eggs and sausage. Breakfast was the most important meal of the day and all four of them needed the energy for the day they were going to have.

"So, like, what are you guys doing after breakfast? Cause, I think we should totes go to the movies. They're playing that new Nick Wolfe movie and I'm like dying to see it!" everyone just stared at Leni with a perturbed glare.

"Uhmm…Leni. You do realize we have classes today. So, we might need to put a pin on that," Lucy pointed out. although it couldn't be seen, she was arching a brow behind her bangs.

Leni's eyes widened. Her once cheerful expression faded into a saddened frown. "O-oh. Right. sorry, I forgot about that. it just gets a little lonely when you guys aren't around." the three of them felt bad for their older sister being cooped up in the apartment. They wish they could do something, but they would have to do that when they get back home. "Don't worry. I'll just ask some of my friends for a get together and see the movie." That was the problem. Leni's friends have been busy with their own lives that they are rarely in Leni's. Even Becky and Chaz barely contacted her.

Instead of stating that fact, all three of them nodded and went back to eating. Everything seemed normal, except for the fact that Lincoln and Lynn refused to make eye-contact. Lucy and Leni noticed it and were a bit concerned.

"Like, are you two okay? you seem quiet," Leni questioned.

"Oh, yeah. We just didn't get enough sleep," Lincoln. Remarked. a fake smile formed on his face.

Lynn didn't say anything. She just nodded and kept on eating. Lucy was staring at the two. More precisely, Lincoln. He was taken aback by the way she was looking at him. Having hung out with Lucy, he didn't have to see her eyes to know she was angry.

Crap! She knows! Beads of sweat fell from the young man's face. Lincoln wasn't entirely sure, but he was certain Lucy knew what was up.

After he was done, Lincoln grabbed his plate and brought to the sink before heading out the door. "See ya, guys. Don't want to miss the bus before it arrives." Throwing his backpack over his shoulder, he waved goodbye and sauntered out the door.

Unbeknownst to the white-haired brother, Lynn watched him walk away. her hand clenching her chest while her eyes drooped. She yearned to walk with her brother and wanted to tell him why she did what she did. However, she wasn't sure how to tell him.

"Hey, Lynn. aren't you supposed to be going too?" Lucy asked.

Snapping out of her daze, the tomboy jumped out of her chair with a contorted expression. "Crap! You're right! We have a test in biology and I can't miss it!"

She bolted to the door with her gym bag and without her sneakers. Unlike her siblings, Lynn would jog to class and home instead of taking any available transportation. It was her way of keeping herself fit while making it to class.

Leni and Lucy were left alone. When they finished their breakfasts, Leni grabbed her keys and purse as Lucy. Just like every morning, Leni would always give Lucy a ride to class. it wasn't that Lucy didn't know how to drive. On the contrary, she was the first of her younger siblings to get her license. It was just her way of giving Leni some sort of purpose.

"Do you really think Lincoln and Lynn are okay, Lucy?" said Leni, worriedly.

Before she reached the door, Lucy turned and paused for a moment. her silence only agitating the older loud. Then she remarked, "I'm sure everything is all right."

Lincoln ran to the biology building. He climbed up to the third floor and straight to the last room on the left. It was dark with the light of a projector illuminating the room. Class was about to begin but there were still a few seats available. He staggered over the middle seat in the first row where he was met with someone familiar.

"Glad you made lame-o. I was afraid I was going to sit next to Stinky Stanley and there's not enough cologne and perfume in the world to tolerate that stench."

"Sorry, Ronnie-Anne. Breakfast at the apartment was getting hectic and conversations between me and my sisters was getting…weird," said Lincoln, having a nervous chuckle.

Sitting beside him, Ronnie-Anne hasn't changed much since she and Lincoln were kids. Her black hair with purple highlights had grown longer to her waist with a lavender scrunchy tied at the base while wearing a white tank top with a purple sports jacket, a pair of blue jeans, and a pair of black and violet sneakers. However, the one thing different about her was that she had blossomed into a beautiful young woman that could make any man lose their minds. Her body was developed with an hourglass figure and well-endowed breasts and hips. Lastly, she was wearing two of earring; one pair being a bar.

"So, did you finish the homework that was assigned to us yesterday?" Ronnie inquired.

Lincoln shrugged. "Yeah, I did. However, I'm not sure if it's right, though."

"W-well, maybe you and I could hang out and study together," she suggested. Her hand pushing a strand of hair away from her face. she leaned over and winked flirtatiously. "I mean, we haven't spent any time together since we were kids. So, it would be nice to catch up on old times."

Lincoln blushed. To the young man, reacquainting with Ronnie Anne would be great but there was a lot on his mind that he needed to deal with. He was about to decline when the door flew open. Walking in was the biology professor, which caused everyone, including Lincoln and Ronnie. they going to have to put a pin on that until class was over.

Running across the track, Lynn was determined to finish the 10-lap run. Her body drenched in sweat as her breathing growing heavy. she was outrunning her other classmates. However, while her coach was telling her she was doing a great job and was amazed by the speed she was going, Lynn's mind was somewhere else. Lynn could only think of her brother and the sin they have committed. She wanted to forget about it and just keep moving forward. unfortunately, she was unable to do so as she still feels what she did was right.

"Lynn! Hit the showers! You've already run enough!" commanded the coach.

Hearing her voice, Lynn immediately snapped out of her funk as she stopped in her tracks. Her other classmates, on the other hand, fell to the ground form exhaustion. Some of them even thanking God that Lynn finally stopped and they could finally let class come to an end. Lynn walked to the women's locker room but before she could step through the entranceway, she felt a hand being placed on her shoulder.

"Lynn. a word." The coach grabbed the tomboy's attention.

Lynn nodded, and they chatted outside of the locker room.

"Lynn. is everything alright? you seem a bit more focused and 1aggressive than you usually are." The coach pointed out. she tried to make eye-contact but was unable to as Lynn kept averting her gaze. "Don't get me wrong. I love the determination and strife but if you keep pushing yourself, it will cause major consequences to your body. So, tell me, is there something wrong going on in your life that's driving you this far?"

Lynn didn't say a word. She merely shook her head and walked away. pursing her lips, the coach was still worried but let it go. "Alright…if you want to talk, then you know where to find me." Lynn didn't look back and just continued walking as she waved goodbye.

She made her way to the great lawn, crossing through the freshly cut grass while hearing hipsters playing folk music on their acoustics. Lynn covered her ears as her face contorted from the agonizing pain of terrible string-playing. God. If Luna hadn't dropped out of high school to pursue her music career, she would have taught these beatniks a thing or two about music.She chuckled under her breath.

She entered the student union and passed by the coffee shop when her somber eyes grew wide with joy. Walking out of the coffee house was her brother Lincoln with a cup of expresso in his hand.

"Hey, Linc…" her smile dissipated.

Walking beside her brother was Ronnie Anne. Lynn watched the two walking side-by-side with a coffee in their hands. Ronnie Anne? I didn't think she would be attending. Why the hell is she and Lincoln being so chummy after all these years? Lincoln and Ronnie Anne hadn't been together after the Santiagos moved away. When the two turned thirteen, they began to drift apart and never went back to video-chatting.

She followed them through the bookstore and out the building. She made sure to be just as stealthy without getting detected. Lincoln and Ronnie Anne made their way to the library. They even held hands with their cheeks red and their eyes dreamily glaring at one another.

Lynn's eye twitched as her ire started to rise but after taking a deep breath, she calmed down and continued following them. Calm down, Lynn. It's just some innocent handholding. Probably reminiscing the good ol' days, and whatnot.Unfortunately, that was all just wishful thinking.

Unbeknownst to the jock, Ronnie Anne leaped and embraced the white-haired boy before passionately pressing her lips against his. Lynn's eyes widened as she backed away from her hiding spot behind the trashcans. She clenched her chest, feeling her heart shattering in a million pieces. The worst of it was that Lincoln didn't pull away. instead, he returned the gesture. He even reached down and clenched her bubble butt while Ronnie did the same. Lynn didn't want to see anymore. so, she dashed as far away from the library's entrance without being spotted.

Lynn's tears flowed like a river. Her thoughts scattered and her vision ignoring the passerby's in her way. Presence of a repetitive voice echoed in her head: Lincoln…you bastard!

Lincoln walked through the front door. His face remaining red throughout his ride back home. Sauntering into the living room, he saw Leni sitting on the couch, wearing nothing but teal lingerie as she watched the Dream Boat. The outfit clung to her curves nicely, emphasizing her well-endowed figure without any chafing. Lincoln was about to spew blood from his nostrils with his cheeks becoming redder than a tomato. This was a habit Leni had picked up for herself from Lincoln. Whenever everyone is gone, Leni would strip down to her brassier and have the house all to herself and since she had dropped out of college, she had a lot of time on her hands.

Hearing the sound of the door closing, Leni turned and screamed. "Lincoln! Look away! I'm not decent!" she covered herself with her arm before throwing one of the couch pillows at her brother. "Warn me when you are coming in, you perv!"

Lincoln was smacked hard in the face. his sister was infamous for having a very strong arm, despite her fragile figure. he was pushed back and stumbled before regaining his footing. Waving his hands nonthreateningly, Lincoln backed away and averted his gaze.

"I'm sorry!"

He ran up the stairs and down the hallway. Taking a deep breath, he waited for his heart to calm down and his face to turn back to normal. First, it's Lynn. Now, I'm attracted to Leni?! This is getting so bizarre. Who's next? Lucy? However, something was off. there were no sounds of death metal blasting through and the neighbors haven't complained about barbells hitting the floor. Is Lynn even home? I know we aren't talking and that she's mad at me, but I'm getting a little worried.Lynn was usually the first one home from classes and would always do her daily evening reps to build up an appetite until dinner began. Although he did have his trepidation, he also smiled and felt some relief. On the bright side, I don't have to grovel in front of the landlord to not kick us out, or give him extra money on our rent.

He opened the door and walked into his room. That was when his face turned completely white. Sitting on his bed was Lynn and she was pissed. Her brow was furrowed to the point that Lincoln thought it was going to fall off. crossing her arms, Lynn stood up and faced her brother.

"Shut the door," she commanded and her brother complied. She motioned over and was close to eye-level. Her gaze staring at the young man's soul. "Lincoln. We need to talk."


A/N: Hey, everyone. this is Kman134. I'm hear to give you the second chapter of Loud House: All Grown Up. Sorry it took so long. I had a lot to do for college. I hope you like the chapter and send as many reviews as possible. Also, if you are going to complain that beatniks and hipsters are different, they I'm not going to apologize as they are the same with similar attitudes but with different clothes.
