"Awright! Another week of school is done! I can't wait to play that new game that came out: DEATH LORDS! That game looks totally badass! What do you think, Lincoln?" When Clyde asked him that question, Lincoln didn't give him any answer. From the looks of it, it seemed that Lincoln's mind was somewhere else.

"Uh, Lincoln? Yo, Earth to Lincoln." Lincoln finally woke up from his daydream.

"What was that, Clyde?"

"I was asking if you're stoked about the new game that came out: Death Lords. Do you think it'll be much better than 'God Of War' or 'Devil May Cry'? It looks really hardcore!" Clyde said. Lincoln's eyes dazed away from reality when he imagined himself getting into bed with Lynn and fucking her brains out as if there'd be no tomorrow.

"Yeah…. Hardcore…" Lincoln said dreamily. Lincoln blushed and shook off such a dirty thought.

"I-I mean that game really does look hardcore! I hope my dad will buy it for me!" Lincoln said.

"Ya know, Lincoln? You've been acting really weird lately."

"W-what do you mean, Clyde?"

"Well, despite your grades improving, you tend to space out once in a while. Dude, you even crashed into someone's open locker when you passed Lynn. What's going on with you?" Lincoln blushed out of embarrassment when he remembered that moment a few days ago.

Three Days Ago

Lincoln was heading to the next class, walking casually down the hallway as if he didn't have a care in the world. When he looked to the left, he caught sight of his sister Lynn talking to some of her friends. When he saw Lynn fix her ponytail and caught a whiff of her scent, his sense of coordination got completely disrupted. He smiled and blushed as he gazed upon his dream-girl.

"… Buh… Buh… Buh…" No thanks to not being able to take his eyes away from his beautiful sister, Lincoln crashed into someone's locker door.

Now

"It's… it's nothing, really. I've been pretty damn… preoccupied with stuff lately, that's all," Lincoln said, feeling pretty damn embarrassed by that moment. Lincoln's eyes widen when he saw Lynn at the corner of a street, waiting for her little brother to accompany her home. Lynn smiled and waved to Lincoln in a slightly flirty way. Lincoln smiled and waved back.

"Hey, Clyde. I'll talk to you later on, okay? I gotta accompany Lynn home. Take care, man."

"Okay, Lincoln. Seeya." When Clyde went a different way to head to his own house, Lincoln and Lynn walked together on their way back to their home. Smiling and blushing, Lincoln and Lynn wrapped their arms around each other's waists as they walked hip-to-hip.

"So… how did school go?" Lynn asked.

"Not too much happened. This week was so-and-so," Lincoln replied.

"That's cool." On their way home, Lincoln and Lynn stopped by at a playground for little kids. Feeling like little kids again, Lincoln and Lynn played around a little, hitting the slide and then the monkey bars and finally the swing. When Lynn pushed Lincoln a little too hard on his swing, Lincoln ended up flying off the swing and landing on his butt. Lynn laughed a little and helped him up. After many minutes of playing, the two teenagers took a seat to get some rest.

"Sorry about that, Linc. I shouldn't have pushed you that hard."

"Nah, don't worry about it, Lynn. It's no big deal, really." Lynn sat closer to Lincoln. Looking away from his eyes, Lynn gently took his hand into hers.

"Lincoln… there's something I want to ask you," Lynn said, blushing a little.

"Sure, Lynn. Knock yourself out." Lynn blushed even harder and brought her lips to Lincoln's ear.

"… Would you…. Would you like to be my boyfriend?" Lynn whispered. Lincoln's jaw dropped and his body-temperature rose to a record-high. This is the first time any girl asked Lincoln to be her boyfriend, and it turned out to be his own sister!

"You want me to be… your BOYFRIEND?" Lincoln asked.

"Yeah, why not? We really connect with each other, you and I. I can't get you out of my mind, Lincoln! You're everything I ever wanted in a man! Please be my boyfriend!" Lynn said. Lincoln nervously looked down to the ground, then he set his eyes back to Lynn. Lincoln licked his lips before answering her question.

"… Yes. Yes, I'll be your boyfriend! No problem!"

"AWRIGHT! WOOHOOO!" Lynn got up from the bench and picked up Lincoln in her arms. Lincoln and Lynn laughed cheerfully and held on to each other as Lynn spun all around with Lincoln, looking as if one accepted the other's marriage proposal.

It was a beautiful Friday night, and it was clearly time for bed. The others were completely knocked out, but Lincoln left his lights on as he lied snugly in his bed and read one of his favorite comic books. He smiled as he imagined himself being the next Stan Lee, the head of Marvel Comics. That would be totally awesome, Lincoln thought to himself.

Suddenly, Lincoln heard a knock at his door. When he opened it, he saw Lynn standing outside his room.

"Lincoln… can I bunk with you tonight?" Lynn asked quietly.

"Sure, Lynn. Did you get into a fight with Lucy again?"

"Oh, it's nothing like that. It's just that… I want to be with you, Lincoln." Lincoln unintentionally licked his lips when he eyed his sister from head to toe. She didn't wear any shorts underneath her extra-large t-shirt, and her hair was still twirled at the back as a ponytail.

"Okay, Lynn. Come on in." Lynn walked right into Lincoln's room, and Lincoln closed and locked the door quietly. Lincoln's blood began to boil when he remembered how he got on top of Lynn and humped her really hard last week. Both of the young teenagers lost total control and went wild on each other, but they didn't go all the way to home base. They were afraid that if they went all the way, they'd end up being a mom and dad at a very young age.

That didn't worry Lynn. Not this time.

"Lincoln… I want you. I want you! Take me, Lincoln!" Lynn pleaded.

"Whoa, Lynn. Just take it easy. Let's not do anything rash," Lincoln said.

"I can't take it anymore! I want you to take me and do with me as you wish! You're my boyfriend now, so PLEASE TAKE ME!" Lynn said. Lincoln noticed that something liquid was dripping down Lynn's legs. Lincoln covered his mouth when he realized that the clear drips of liquid was coming from her pussy. Breathing heavily, Lynn slowly removed her extra-large t-shirt and tossed it aside to the corner. Lincoln started to harden when he gazed upon Lynn's beautiful body as she wore nothing but a black bra and a red panty.

Lynn strutted towards Lincoln and lightly pushed him to make him fall back into his bed. Lynn slowly mounted on top of Lincoln and slowly removed her bra. The girl gazed into her boyfriend's eyes and exposed her tits to Lincoln for the first time, making Lincoln's mouth drop big-time. Feeling the hunger building up, Lynn undid Lincoln's buttons of his pajama-shirt and whipped his shirt wide-open, revealing his well-chiseled body. Lynn licked her lips and ran her soft hands all over his body, enjoying how rock-solid Lincoln's muscles felt from her hands.

Lincoln made Lynn lie on her back and lied on top of Lynn, running his hands all over her body and slowly licking Lynn's neck. Lynn closed her eyes and purred like a kitten as she wrapped her arms around his body and slowly wrapped one of her legs around his waist.

"Lincoln, I want to be yours! Please, Lincoln! Make love to me!" Lincoln got off of Lynn and prepared to take her wet panties off. When Lynn lied on her stomach, Lincoln quickly whipped her panties right off and tossed it away. Lincoln's heart beat like mad when he set his eyes on his sister's irresistible body. There wasn't a hint of body-fat on her. She had beautiful slender muscles, and her ass was quite plump and juicy. Lincoln slowly placed his face on Lynn's nice ass and rubbed his face deep into it. That made Lynn squeal with excitement.

"Oh my gosh, Lincoln! You're such a dirty boy!" Lynn exclaimed. Lincoln slowly stuck out his tongue and started licking Lynn's ass. The young man would sometimes give it a lot of quick licks and once in a while give her ass a really long, big lick. Lincoln then spread her but-cheeks open to reveal her anus. Lincoln opened his mouth wide and stuck his tongue right into her butt-hole. Lynn let out a huge scream of excitement as she buried her face into Lincoln's bed.

"Holy shit, Lincoln! It feels so fucking good! Lick it LICK IT LICK IT!" Lynn moaned uncontrollably when Lincoln continued to attack Lynn's anus with his sly tongue. Lynn got on her hands and knees and stuck her ass out even more so she could feel more of Lincoln's tongue. Lincoln dug his face deeper into Lynn's ass and began to stick his tongue into her pussy. Lynn moaned like a banshee when that happened.

"AAAAAAAH! AAAAAAAH! YES! YEEESSS! YEEEEESSSSS! AAAAAAAAAAAAAAAAHHHHH !" Lynn screamed. Lynn started twerking her ass as Lincoln continued to eat her pussy while stuffing his face into her juicy ass. He then gave Lynn's ass a really good spank.

"Oh yeah! You are so fucking finger-licking GOOD…" Lincoln mumbled in Lynn's ass. Not wanting Lincoln to have all the fun, Lynn took her ass away from Lincoln's face and pushed his back into the bed. By the time Lincoln lied on his back, Lynn pulled Lincoln's pants and underwear right off and tossed it away. Lynn covered her mouth in shock when she took a good look at Lincoln's dick.

"Holy SHIT! YOU'RE FUCKING HUGE! From now on, I should call you BIG brother!" Lincoln blushed out of embarrassment from that statement. Feeling her mouth water, Lynn grabbed a hold of Lincoln's cock and started jerking it, which made him moan with delight. Loving how big Lincoln's one-eye monster was, Lynn started licking away at Lincoln's shaft and then flickered her tongue on Lincoln's tip. Lincoln closed his eyes and bit his lower lip.

"Oh, Lynn! You're the perfect girlfriend I always wanted! Keep going!" Lincoln exclaimed. Opening really wide, Lynn took in as much of Lincoln's dick as she could and slowly bopped her head up and down on it. Lincoln's breathing was completely out of control as he felt Lynn's tongue swirling all around his cock and at the same time felt Lynn's hot lips sucking away at his dick. The faster and harder Lynn's head was bopping, the louder Lincoln moaned away. Lincoln then grabbed onto Lynn's head and made himself thrust his dick into Lynn's mouth. Lynn touched herself and felt her pussy getting wet as she continued to blow away Lincoln's mind by blowing away on his dick.

Lynn finally took her mouth out of Lincoln's cock. As she lied on her back, she gazed into Lincoln's eyes and opened her pussy wide for Lincoln. Lincoln locked his hungry eyes on Lynn's well-shaven pussy.

"Lincoln… this is the 'Point Of No Return.' Are you ready to go beyond this point?" Lynn asked. Lincoln looked away, having a look of concern.

"I… I don't know, Lynn. I don't want you to get pregnant," Lincoln said.

"It's okay, Lincoln. I'm wearing a female condom. I grabbed one from Luna's room when she didn't spot me. Please put it in, Lincoln. You saved me from those evil men, and this is how I want to thank you. You deserve it more than anyone else, Lincoln. Please…. Fuck me…" Lynn said. Breathing heavily through his nostrils, Lincoln placed his hands on Lynn's hips and aimed his cock right towards her lovely opening.

"Okay. On the count of three. One… two…"

"THREE!" Lynn screamed. Lincoln plunged his hot rod right into Lynn's hot sex. Lynn let out a huge screech, closed her eyes tight and gritted her teeth. Lincoln felt truly worried when he saw pain written all over Lynn's face.

"LYNN! Are you all right? I'll stop this right now-"

"NO! I WANT IT! I WANT IT ALL !" Lynn quickly wrapped her legs around Lincoln's hips. Feeling Lynn's inner walls of her pussy tightening around Lincoln's cock, Lincoln thrusted into Lynn harder and faster. Every thrust Lincoln made caused Lynn to scream with joy as she felt her pussy's inner walls embracing Lincoln's rod. Lincoln started to moan as well as he continued to go in and out, in and out of his older sister.

"Oh, Lynn! It's so damn good! I LOVE IT, LYNN! I LOVE IT !" Lincoln screamed!

"AAAHHH! AAAAAHHH! MORE! MORE! MOOOREEE! FFFFUCK MEEEEEE !" Lynn screamed back. Not giving a damn whether or not the enforced walls would keep the moaning and screaming muted out, Lincoln pounded away into his beloved Lynn. Lynn ran her fingers through her hair and unintentionally removed her band, undoing her ponytail and letting her hair down like wild. Lynn thrusted her hip into Lincoln's, going with the flow and screaming away from Lincoln's incredible entry.

Lynn sat up and held onto her beloved as he continued to thrust away into Lynn. Feeling tears of joy running down her eyes, Lynn bounced up and down on his cock. Lincoln clutched onto Lynn's body and thrusted right back into her.

"Oh, no. I think I'm going to cum! I'm cumming! I'M CUMMING!" Lincoln screamed!

"ME, TOO! I'M CUMMING! I'M FUCKING CUMMING! HOLY SHIT! AAAAAAAAHHHH! " Lynn and Lincoln climaxed together, screaming with joy so damn loud that they both nearly lost their voices. When Lynn went limp and let go of Lincoln, Lincoln finally took himself out of Lynn's body. Both teenagers collapsed on the bed and took a serious breather, having nothing left in them.

"That…. That was seriously awesome," Lincoln said.

"You are so fucking amazing, Lincoln Loud…" Lynn said, eyeing Lincoln in a hungry way. Lincoln and Lynn embraced one another and kissed.

"Lincoln?"

"Yeah, Lynn?"

"You're the best brother in the whole world."

"Thanks, Lynn. I love you."

"I love you, too." As they closed their eyes, they both fell asleep.
