Lincoln Loud was asleep in bed, but his sleep was soon interrupted by the sound of his phone, he shot up and grabbed it as he looked at it he saw a text from Lori holding, her newborn daughter Loan saying Happy Birthday, During the summer Lincoln and Lori continued seeking around to fuck each other sometime late at night or even during the day when they are careful after the summer Lori moved to Great Lake City to live with Bobby and was surprised to find out she was pregnant, of course, Lori told Bobby that he was the father and thank god he believed her, but Lori and Lincoln knew that Loan was Lincoln's, it shocked him at first being a father at such a young age, but he learned to accept it. Lincoln then replied with thanks and an "I love you". The boy soon hopped out of bed and headed towards the bathroom as he did, he looked at Leni's room and found the door opened, he looked inside and found Leni fixing herself in the mirror.

"Hey, Leni." Lincoln greeted.

"Hey, Linky, happy birthday!" Leni said as she walked up to him and gave him a tight hug, shoving his face into her breast.

"How's being twelve years old treating you?" She asked.

"Much better." He said

"That's good because I have a special gift for you today, I think you're going to love it."

"Awesome do you think I can have it now?" Lincoln asked

"Not yet, you have to wait okay." She said as she kissed his nose and puts him down, now goes get ready." Leni said, Lincoln then left and went to the bathroom. Leni then went to her vanity and pulled out a photo of Lori and Lincoln holding Loan. She soon smiled and looked at Lori's bed.

"You may have beat me to Lincoln the first time, but I'm not losing him this time." She said as she lays down on her bed.

-Meanwhile-

Lincoln was at the family restaurant with Clyde and the others they all exchanged gifts too the white-haired boy.

"Happy Birthday Lincoln." Stella said, "Gotta say being twelve must be nice." Lincoln nods

"Yep, I can finally work with my sisters with their babysitting jobs and maybe I can get some more respect around here." He hoped

"Glad to see that your not a bummer, anymore." Zach said

"What? When have been a bummer?" Lincoln asked

"When your sister Lori moved away." He stated Lincoln as sighs.

"Okay yes, I may have been kind of a bummer." He said

"Kinda? You were more of a bummer then Clyde when she moved away." He said.

"I wasn't that much of a bummer." Clyde defended.

"Dude, you chained yourself to Lori's car, so that she wouldn't move away," Lincoln said

"Hey but I moved on, Penelope and I have a solid relationship," Clyde said

"Weren't you dating Haiku?" Stella asked.

"Don't worry about that." He said. "So I'm not clingy anymore." He said, just then he heard a ding, he looked at his phone and saw that it was Haiku.

"Oh gotta run, Haiku wants to see me." Clyde said as he slid from the table and gave Lincoln a fist bump and left.

"So what's on the agenda, Linc?" Liam asked

"Well, Leni told me that she got a surprise for me back home but for now I'm all your guys." He said. Just then, everyone, he knew popped out and started their little party.

-Later-

Lincoln and Leni were walking up the steps to the house he was pretty exhausted, Leni had to make sure that she got his gift-ready, she then helped him up the stairs and placed him on her bed.

"Okay, just lay down Linky, I think you had a sugar crash." Leni said

"Mmm Lori, can I have some more cake?" He said in his daze. Leni then looked "I don't have cake but you'll love this." She said as she pulled down his pants, revealing Lincoln's hard-on, Leni smiled as she started to rub her hand on crotch she took it in her hand and started pumping it up and down, slowly, Lincoln moaned as her soft hand pleasure him.

"Lori that feels so good." He said as he gripped the sheets.

"Really, so do you like it fast or slow." She said as she changes between the speeds.

"Oh please go faster." Lincoln begged, Leni then granted him his wish and she started gradually going faster.

"You like that, Linky?" She asked.

"I'm cumming Lori!" He moaned, Leni then opened her mouth and wrapped it around her brother's dick and started sucking on it.

"Lori!" He gritted.

"Gho Ahead Lincoln, cumm in my mouth!" Leni mumbled

"LORI!" Lincoln grunted as he gripped her sheets as he cums in her mouth, white streams of his seed filled her cheeks, but she managed to swallow all of it.

"Wow, that's a lot." Leni said, she looked over and saw that he was still dazed

"Lori, that feels good." He mumbled, Leni then puffed her cheeks.

"I bet Lori didn't do this." She said as she pulled down the top part of her dress to reveal her luscious breast, they grew even larger since Lori moved away, and wrapped them around his member and the soft flesh made Lil' lincoln twitch, she started to move her breasts up and down, Lincoln moaned louder as she picked up the pace.

"Lori it feels so amazing." He moaned.

"That's it!" She said as she took off her clothes and climbed on top of him.

"Wake up Lincoln!" She said.

"L-Lori?" He asked his vision cleared and he saw Leni looking at him with anger.

"L-leni?" He asked, Leni then bends down and kisses him as they parted they looked into each other's eyes.

"It's not fair, you keep thinking about Lori even when I was blowing you, you don't need her, you have me, I can make you happy too." She said as she lifted her hips over his crotch she then slid down his shaft, she moaned as she lifted her hips up and then down. Leni's breast soon swayed in front of him as she moved, Lincoln couldn't help himself as he grabbed them and started sucking them, Leni moaned loudly, Lincoln then thrust his hips upwards slamming into his older sister.

"You don't need Lori, she left you, you can do this with me anytime, I won't leave you." She said, Lincoln then flipped them over. Now that he was on top, he raised Leni's legs up and drape them over his shoulders, gets a firm grip on her hips and started thrusting hard and fast.

"That's it little brother release all your frustrations from Lori on to me!" Leni said. Lincoln then bends over and kisses her while fondling her breasts.

"Harder Linky, Harder!" Leni thought.

"I'm gonna cum again, can I…" Leni then kisses him silencing him.

"I want your baby too." She said, Lincoln then lost it, he pulled out of Leni and pulled her hips upward, Lincoln then climbed on top slammed back in her, his hips moved with great speed.

"Have my baby, LENI!" He moaned as he shot his cum down, filling her up, Leni yelled in pleasure as she felt herself being bred by her baby brother. Lincoln then rested on her stomach and Leni petted him.

"You're going to be a great dad, Linky." Leni said

-Now-

Leni was on all fours as her large breasts swayed to the rhythm to Lincoln's thrust. The man then bends over and grabs them and starts to fondle them.

"I'm cumming!" The two soon moaned and fell onto the bed, Lincoln rolled off his sister and lay down next to her. Leni then snuggled up to her lover and he petted her head. The moment was soon ruined when they heard a knock on the door.

"Mom, Dad are you in there?" a voice called out.

"Yeah, we're here Liena." Leni called, the door opened and a plump young girl came, wearing a light green nightgown came in.

"I wasn't disturbing you was I?" She asked

"No no we just finished was there something you needed?" Leni asked

"Well, I just wanted to make sure that we're still on for shopping tomorrow Papa?" She asked

"Of Course, I hope you don't mind that Leia comes with she said that she need some ingredients for her cookies." Lincoln said

"I don't mind the more the merrier." She said as she left with a big smile on her face, Lincoln then lays back and snuggles with Leni again.

"Your such a good daddy." Leni said as the two shared a kiss.
