Author's Notes:

Welp, this is where the fic ends! However, I think there's a bit more that can be done with this story! If you want me to write a sequel, continuing from where my friend left off, let me know!


After Leni and Lincoln's "education" session was done, the two spent the rest of the day with Esther doing silly things like playing hide and seek, watching the dream boat, and eating macaroni and cheese on the couch. While Lincoln was sloppily munching down on his Mac n' cheese, a big mess of cheese got all around the corners of his mouth, and somehow also ended up on his cheeks.

"Lincy! You got cheese all over your face!" Leni says with a pouty face.

Lincoln gulps down his food, "Oh sorry, I'll go ahead and clean it up."

"Wait, let me take care of it." Leni says with half-lidded eyes.

"Huh-" Lincoln started.

Before he could continue Leni leaned into him and gently dipped her tongue on his cheeks, and licked up the mess. It reminded Lincoln of how a kitten would lap up milk in a milk bowl, only Leni somehow seemed a lot cuter. Lincoln rubbed her head, and she immediately got the hint. She started purring and curling up around Lincoln. They both looked at each other and laughed.

They continued on for about a couple of minutes, and then they heard the doorbell ring. Lincoln got up and opened the door. Sure enough, it was all the sisters who had been gone the entire day.

"Oh! Hey guys! How was your day, guys?" Lincoln greeted.

"It was LITERALLY perfect! Bobby is such a romantic!" Lori says as she holds the flowers she got from her date.

"MCSWAGGER WAS ROCKIN' DUDES!" Luna shouts as she bursts through the door.

"I actually made some money from working on my mime skills!" Luna says, pulling out the cash from her pockets.

"You chumps better be ready for the next game of catch! Because I just so happened to perfect my curveball!" Lynn gloats with a smug smirk.

"Me and Rocky went grave watching. It was pretty great." Lucy says with her usual blank expression.

"DAIRYLAND WAS AWESOME!" Lana shouts with a giggling Lily in her hand.

"Yea except for you know, THE PART WHERE YOU PUKED ON ME! TWICE!" Lola exclaims.

"Ah come on. I told you it would wash out!" Lana says.

Lily then spews puke in Lola's face.

"PFFFFFFT HAHAHAHAHA!" Lana screams in hysteria as she runs up the stairs with Lily.

"LANA!" Lola shouts as she chases after her sister.

All the sisters ran to their rooms, except for Lori who had noticed that Lincoln and Leni were the only ones at the house today.

"Did you enjoy your day with Leni?" Lori asks Lincoln.

"Yeah! I loved it! Leni taught me a lot of things today!" Lincoln says with glee.

"Oh really? Like what?" Lori questions as she knows that sometimes Leni isn't the sharpest knife in the drawer.

"About djsgaksbsidhsmshsibdkm." Lincoln tries to explain through Leni's hand covering his mouth.

"Like, about fashion design!" Leni says in her make-up blonde girl tone.

"Good. Maybe we can help Lincoln FINALLY change into something besides that stupid orange shirt everyday." Lori says, rolling her eyes in relief.

As Lori walks up the stairs, Leni stares at her with venom and thinks to herself (The fuck did you just say about my Lincy poo's shirt?)

As Lincoln then takes Leni's hand off of his mouth, he becomes severely confused by Leni's actions.

"Why didn't you tell her about our-" Lincoln starts only to be stopped by Leni's hand yet again.

"Shhhhh, we'll talk about that later." Leni says seductively.

"But right now-" Leni starts as she rubs her hand on Lincoln's bulge, "It looks like I'm gonna have to help you again." She says with half-lidded eyes.

"Oh boy!" Lincoln says excitedly.

Leni has no idea why, but every time Lincoln gets genuinely happy about her giving him sexual pleasure it turns her on that much more. Leni takes Lincoln up the stairs and into his room.

"Lincy. If you don't mind, I wanna try something else. I think it'll make you feel even better…" Leni says whilst undressing.

"Sure! I'm positive anything you do will feel great!" Lincoln says while taking off his clothes like a goofy cartoon character.

"Good." Leni says with an evil smirk.

"Just sit down and let me do all the work okay, Lincy?" Leni instructs.

"Okay!" Lincoln sits on the bed and lets his erection spring freely.

"Mmmmmm" Leni moans in pleasure from just seeing Lincoln's member. She gets on her hands and knees and playfully crawls towards Lincoln. When she reaches him, the tip of her nose touches Lincoln's shaft and sends a tingle down his spine.

"Oh gosh Leni, I'm really excited to try this new method out!" Lincoln moans in pleasure.

Then at that moment, with no warning at all , Leni puckers her cherry, red lips and plants them on Lincoln's tip.

"Ahhh! Leni, that's not a boo boo!" Lincoln squeals in innocence.

That was the last straw, Leni could no longer control herself. She needed all of Lincoln. She then slowly enveloped Lincoln's throbbing erection into her mouth. She let her tongue cover Every inch of Lincoln's massive shaft in her warmth.

"Gee willikers! That feels amazing!" Lincoln shouts as he arches forward holding onto Leni's head. Leni then proceeds to bob her head up and down giving Lincoln the best blowjob he will ever experience.

After only about two minutes, Lincoln feels his essence about to explode.

"Leni! I-I-I'm gonna burst" Lincoln squeals.

Then all of a sudden, Lincoln starts spraying his love down Leni's throat in massive, thick loads. With each burst of cum, Leni's mouth would expand and she would drink it all up. She wouldn't dare spill a drop of her dear brother's affection. After she gulped it all down and cleaned Lincoln's penis she raised her head up to reveal a sexy smirk and asked, "So… how did that feel?"

"Awesome." Lincoln says through continued pants.

"But…" Lincoln starts.

"Hmm?" Leni looks at him with a tilted head of confusion.

"It's not fair!" Lincoln exclaims.

"What?" Leni asks.

"You do all of this stuff to make me feel good, but what have I done for you? I want to make you feel good too, Leni!" Lincoln pleads.

Leni just looked at him with shock. Those words of selflessness made her heart pound like crazy. She loved Lincoln before, but now she started looking at him and how much of a man he's becoming. This whole time he was still worried about Leni having a good time as well.

"OHH LINCY!" Leni says as she tackles Lincoln to the bed.

"I can't believe how grown up you are! You're supposed to be my little Lincy!" Leni says as she's tearing up into his shoulder. "You should never have to worry about how good I'm feeling during this! I'm doing it for you after all!"

"Negative. If we're gonna do this then I need to know you get pleasure out of it too!" Lincoln pouts.

Leni then wipes her eyes with her hand and stops crying. "Okay Lincy, we can do one other thing, but I need you to answer me right now okay?" Leni asks seriously.

"O-okay." Lincoln replied nervously.

"What we're about to do is something only two people who really really love each other do. So before we take that step, I need you to tell me that you love me with all your heart, and that you're okay with anything that happens next. I don't want to force you into anything you don't want to do."

When Leni says all of this, she looks extremely serious. All of the mushy lovey dovey stuff from earlier completely wiped off her face. All of the list and pleasure gone. She knew exactly how serious this situation was, and she wanted to make sure Lincoln knew too. Lincoln wasted no time and took Leni's face into a deep passionate kiss. His tongue explored every nook and cranny of her mouth. After a while he broke the kiss, leaving a trail of saliva connected to his and Leni's mouth.

"Leni, I love you with all my heart and no matter what happens here, or what happens in the future I will NEVER stop loving you." Lincoln says with confidence.

This was all the confirmation Leni needed. She smiles cutely and pecks Lincoln on the lips. She pulls down her panties and reveals her womanhood. She straddles Lincoln between her legs, and opens up her opening to reveal to Lincoln all of her privacy.

"This is a vagina, Lincy." Leni explains.

Lincoln stares at the fleshy walls of his sister's genitals. "It's… it's so beautiful." Lincoln says in shock.

This causes Leni to look away blushing.

"When a man's penis goes into a woman's vagina, it connects the two into a bond of eternal love." She tells Lincoln.

Leni then points his shaft towards her opening and looks at him with a loving face.

"Are you ready, Lincy?" She asks as if to prepare him for what's about to happen.

Lincoln gulps down through a dry throat to get rid of any last minute doubts. "I-I'm ready."

Leni then drops herself right onto his erection leading both to moan in the sudden pleasure surging through each other.

"Oh god, Lincy! I need more!" Leni says, hugging him tightly, and bouncing on his member.

Lincoln was also rapidly thrusting into Leni needing more of the enveloping feeling of her wet warmth. "Leni! It's so tight!"

"I'm- ohhhhh- I'm- ahhhh- I'm so glad you're enjoying this Lincy!" Leni mutters out between moans.

Unsurprisingly, neither one lasted that long due to the intense love for each other.

Lincoln grabbed onto Leni's curvaceous hips, "Leni! I'm close!"

"M-me too!" Leni squeals.

Then both moan in pure ecstasy as they release their orgasms. Lincoln pumped Leni full of his seed while she was still riding out through her orgasm. Leni and Lincoln just lay there still connected to each other staring longingly at each other.

"Lincy. I need to tell you one more thing." Leni says.

"What's that Leni?" Lincoln asks while his eyes are closed with a satisfied smirk.

Leni then pets his head and whispers in his ear. "Nothing much, but I need you to remember this and never forget it."

"This is just our little secret…"

The End.
