(The next morning, Lincoln and Lola are still in bed together. However, Lola wakes up first and lovingly stares at her slumbering bedmate.)

Lola: "Aw, he is so cute…"

(Lola puts her hand on his shoulder and lightly shakes him.)

Lola: "Wakey-wakey, Linky…"

Lincoln: (wakes up) "Oh, good morning, Lola."

(The door opens to see Adult Lily, in a lavender bathrobe.)

Lily: "Morning, Lincoln. Today's my date with you."

Lincoln: "Oh, that's right. I wonder what you have in store." (to Lola) "See ya later, Lola."

Lola: "Later, Linky…"

(Lily takes Lincoln's hand, as the two leave Lola and Lana's room.)

Lincoln: "We should get dressed first, Lily."

Lily: "Oh, right! Let's do it in your room."

(Lily goes to Lincoln's room to get dressed. Lincoln gets dressed in his adult clothes, he turns to see Lily's adult clothes. She wears a lavender long-sleeve shirt under white overalls, with white socks and purple velcro sneakers.)

Lincoln: "You look so cute, Lily!"

Lily: "Thanks, Lincoln! Wait until you see where we're going!"

(Lily takes Lincoln's hand as they run out of the house.)

Lincoln: "Lily, where are we going?"

Lily: "I can't ruin the surprise! You'll see!"

(Eventually, Lily and Lincoln make it to Ketcham park.)

Lincoln: "The park... Sounds very nice and simple."

Lily: "Yep, and it's a nice day out."

(The two head further into the park, then come across a pair of swings.)

Lily: "Oh, the swing set! I've never been on those before!"

Lincoln: "Well, since you're a big kid now, how about I show you how to do this?"

Lily: "Okay!"

(Lincoln and Lily head towards the swing set, as Lily sits in one of the swings. Lincoln pushes her, as she goes higher and higher.)

Lily: (giggles) "Higher!"

(Lincoln pushes Lily, as she goes higher.)

Lily: "WHEEEEEE!"

Lincoln: "So much fun, isn't it?"

Lily: "It's really fun! Woo-hoo!"

(Lincoln pushes on Lily one more time, but it was so hard of a push that Lily ended up launching off the swing and faceplants into the grass several feet ahead with a thud.)

Lincoln: (distressed) "OH, MY GOD! LILY!" (runs to Lily's body) "LILY, ARE YOU OK?!"

Lily: (raises head) "That… Was… AWESOME!"

Lincoln: "Oh, it was?"

Lily: "Let's do it again, Lincoln! I wanna fly further!"

Lincoln: (laughs) "Since when did you turn into Lynn?"

Lily: "I'm just excited about experiencing all the thrills I couldn't do as a baby! Let's go find more fun around here, Linky!"

(Lily runs around the park, while Lincoln follows suit. He finds her sitting on one end of a see-saw.)

Lily: "Come on, Lincoln! The more, the merrier!"

(Lincoln sits on the other end of the see-saw, as they go up and down.)

Lincoln: "Y, know, Lily-pad… This takes me back to when I was a baby like you, when I was on it with Lynn."

Lily: "And Lynn hurt you?"

Lincoln: "Um, close enough…"

Lily: "You're my most favorite person in the family, Lincoln. You are always so sweet."

Lincoln: "Aw, thanks." (blushes)

Lily: "And there's been so much going on in my little baby mind that I've been wanting to tell you for so long…"

Lincoln: "Such as?"

Lily: "How come you're the only boy in the family, besides Daddy?"

Lincoln: "That… I dunno about. Lucky coincidence, I guess?"

Lily: "And why do you and Lucy have different colored hair from the other siblings, including me?"

Lincoln: "Genetics, maybe..."

Lily: "Why couldn't you do the stuff you were doing with Lori and Leni with the rest of us before the whole age serum thing?"

Lincoln: "We were afraid that you guys would break the three of us up… Plus, most of you were way younger than me, and I'm not into that loli stuff. Personally, I prefer girls close to or greater than my age. But that all changed with this aging serum. And that's the only way I can feel comfortable loving the rest of you."

Lily: "Whoa…"

Lincoln: "I didn't say I never loved you girls at all. I meant it in the romantic sense."

Lily: "Dang…"

Lincoln: "Yeah, I feel better now saying all that."

Lily: "Lastly, why does Mom still look as pretty as me and the other sisters after having 11 kids come out of her stomach?"

Lincoln: "Hmm… Maybe she got dialed down after finally having you."

Lily: "I suppose that's true."

Lincoln: "Is that it?"

Lily: "Ooh! One more! If we have so many people that can drive, why do we only have 1 car?"

Lincoln: "Um, I dunno. We've had Vanzilla for years now…"

Lily: "I mean, there was that one time Daddy got a new van…"

Lincoln: "Yeah, only to hog it to himself… Come to think of it, he could've kept it, as well as Vanzilla, if he wanted to."

Lily: "Yeah… Anyway, can you teach me how to play basketball in the courts over there?" (points to the northwest)

Lincoln: "Sure."

(The two get off the see-saw and go to the basketball courts. It then shows Lincoln beside a net holding a basketball, with Lily watching him.)

Lincoln: "The objective of this game is to take the ball and get it in the net."

Lily: "So… Do you just try and throw it in, or get up to the net and throw the ball down it?"

Lincoln: "From what I know, both methods work. But, it's easier to just throw the ball into the net from the ground instead of dunking it."

Lily: "Oh, okay! Lemme give it a try!"

(Lincoln tosses the ball over to Lily, as she studies the net's position relative to him with immense concentration. She throws the ball in an upward arc towards it, as it rolls about the net's rim.)

Lincoln: "C'mon, c'mon…!"

(Fortunately, the ball rolls towards the center and falls through the net.)

Lily: "YAY!"

Lincoln: "Wow, and on just the first try! Good going, Lily-pad!"

Lily: "I'm gonna make another one!"

(Lily gets the ball and throws it at the hoop again. Only this time, the ball ricochets off the board above the net, bounces towards her a little, and rolls to her feet the rest of the way.)

Lily: "Aw, man! I thought I had it!"

Lincoln: "Don't feel bad. Not everyone gets the perfect shot repeatedly…"

(The two hear familiar and enticing music, and turn their heads to see an ice cream truck near the park's main entrance.)

Lily: "Oh my gosh! Ice cream!"

(Lily runs to the ice cream truck, with Lincoln walking behind her. The two make it to the truck.)

Ice Cream Vendor: "What can I do for you two?"

Lily: (eager) "You have anything that's vanilla flavored?"

Ice Cream Vendor: "Yes, ma'am!" (takes out a vanilla cone) "Here you are!"

Lily: "Thank you!" (gives vendor $1)

Lincoln: "I'll have a rainbow sherbet."

Ice Cream Vendor: "Here you are!" (takes out a rainbow sherbet cone)

(After Lincoln gives the vendor the money for his cone, he and Lily sit on a nearby bench to eat their frozen treats.)

Lily: "I like vanilla because it always reminds me of you and your white hair, Lincoln."

Lincoln: "Very cute, Lily."

Lily: "And the texture reminds me of all the cream you shoot out your wee-wee when we do it."

Lincoln: "Oh, you cheeky little girl, you…"

Lily: (giggles)

Lincoln: "So, what do you want to do now?"

Lily: "Now that I'm thinking about it, I was thinking we could have some intimate fun, if you catch my drift."

Lincoln: "I like the way you think!"

Lily: "Thanks, but let's do it somewhere safe."

Lincoln: "Okay. But where?"

Lily: "The bathrooms…"

(Lily takes Lincoln's hand, as they rush into the mens' room and into a large stall.)

Lincoln: "We gotta make this quick before we get caught."

(As Lincoln sits on the toilet lid, Lily gets on her knees, unzips Lincoln's pants, and pulls out his member from the fly in his boxers. She stares at him lustfully.)

Lily: "I'm ready for my cream-gusher popsicle, Lincoln…"

Lincoln: "Go for it, Lily."

(Lily kisses the tip of Lincoln's penis, then proceeds to lick around it, in addition to the rest of his length, as he grins with content.)

Lincoln: "Yeah, suck on my wee-wee, Lily."

(Lily takes Lincoln's tip into her mouth and slowly sucks on it, looking up at him lovingly.)

Lincoln: "Oh, yeah…"

Lily: "You like my tongue?"

Lincoln: "Oh yeah…"

(Lily fondles Lincoln's balls, as he shoots his load into her mouth.)

Lily: (licks lips) "Tastes just as good as my ice cream…"

Lincoln: "Thanks, let's go."

(Lincoln starts to get up, but Lily holds down on his legs to keep him on the toilet lid.)

Lily: "Ah, ah, ah… I'm not finished. I want this popsicle in my butt."

(Lily undoes her overalls, letting them drop to the floor around her legs, and pulls her panties down to reveal her bare nethers. She turns around and grips Lincoln's cock from behind, as she makes it poke and prod at the opening of her asshole.)

Lincoln: "Lily, someone's gonna hear us."

Lily: "No, they won't. Just as long as we smooch the whole time."

Lincoln: "Okay, fine… Make it quick."

(Lily sticks her asshole onto Lincoln's cock, as she goes up and down. She wraps her arms around Lincoln's neck and leans in for a passionate kiss.)

Lily: "I love your popsicle…"

Lincoln: "I guess your new favorite kind of ice cream would be vanilla popsicles, huh?"

Lily: "Yes!"

(Lincoln reaches underneath Lily's shirt and plays around with her breasts, as he anally pounds her.)

Lily: (giggles) "How do you like my boobies, Linky?"

Lincoln: "They're the best! They're really soft and carry a lot of milk!"

Lily: "Allow me to give you a breastfeeding, then…"

(Lily lifts her shirt up and unclips her bra to reveal her breasts. Holding them in her hands, she leans in closer so Lincoln can suckle on both of them interchangeably.)

Lily: "You enjoying that milk, brother?"

Lincoln: "Yep, I love all of your milk."

(Lincoln thrusts into Lily's asshole some more, until he unleashes his load and fills it up with his special yogurt.)

Lily: "Sweet, sweet cream…"

(Lily rips away some toilet paper and wipes the cum out of her asshole. Lincoln pulls his pants and underwear back up as Lily puts her clothes back on.)

Lily: "Hey, how much time do we have until we have to go home?"

Lincoln: "It's only 4:30."

Lily: "Hmm… What do you wanna do, Lincoln?"

(Lincoln takes a look at Lily's hair, which is long and goes down to her back. He gets an idea, as he takes Lily's hand.)

Lincoln: "We're gonna give you a makeover."

Lily: "Ooh!"

(Rushing out of the bathroom, the two go into a hair salon.)

Hair Stylist: "Hi! What can I do for you this afternoon?"

Lily: "Me and Lincoln agreed on getting myself a makeover."

Hair Stylist: "Right this way, ma'am."

(The hair stylist shows Lily towards a chair as the stylist puts a hair cloth over her body. Lincoln sits in one of the waiting chairs and starts reading through a magazine.)

Hair Stylist: "What kind of hairdo do you want, sweetheart?"

Lily: "Something short and sweet, with a small ponytail in the back pointing up."

Hair Stylist: "Coming right up, darling."

(The hair stylist dials Lily's head back, as she cleans her hair out with water.)

Hair Stylist: "So, what's your name, sugar?"

Lily: "Lily. Lily Loud."

Hair Stylist: "What a beautiful name there, girl. I'm Tasha."

Lily: "Hello, Tasha. I hope you do my hair extra special."

(Tasha dials Lily's head forward, as she blows her hair with a hair dryer. When she's done, Tasha gets a pair of scissors and starts cutting Lily's hair. Lincoln is still browsing through magazines looking bored.)

Lincoln: "There's nothing in here but girls' stuff. They could have ones about new movies coming out, new tech… But nope. This is just it."

(Lincoln tosses one of the magazines to the side, as he pulls out his phone. Tasha continues to cut Lily's hair until it goes down to her neck.)

Tasha: "A little of this, and a little of that… And done! Oh, and one more thing."

(Tasha takes out a lavender scrunchie and wraps some of Lily's hair into it, forming a cowlick at the back of her head. She then takes the hair cloth off Lily.)

Lily: "Ooh, how do I look?"

Tasha: "Here, have a look, hun." (gives Lily a hand-mirror)

Lily: (looks at the mirror) "Wow! I look great!"

Tasha: "Would Lincoln want a makeover too?"

Lily: "I'll ask him. Hey, Lincoln! You want Tasha to do your hair too?"

Lincoln: "No thanks. I'm good."

Lily: "How do I look?"

(Lincoln looks up from his phone to see Lily's new haircut. Her hair is a little longer than Luna's pixie-cut, but she also has a cowlick sticking up in the back like the tuft of hair she had as a baby.)

Lincoln: "Now your look just screams cute, Lily-pad."

Lily: "Aw, thank you, Linky."

Lincoln: "Anyway, Tasha, was it? How much was Lily's makeover?"

Tahsa: "Okay, with the haircut, washing, and trimming, that'll be $17.73."

(Lincoln pays Tasha the money, as Lily gives her brother a kiss on the cheek.)

Lily: "Don't worry, Linky. Once we're home, I'll make sure all that money was well spent…" (hugs Lincoln)

Lincoln: "Aw… Come on… Let's head home..."

(The two leave the salon and head for home.)

Tasha: (from open door) "Bye, you two! Please come again soon!"

(When Lincoln and Lily get back to the Loud House, they can smell food being prepared once they get inside.)

Lily: (sniffs) "That's definitely the smell of fish fry."

Lincoln: "Fish fry?!"

Lynn Sr.: (from the kitchen) "Dinner's ready, everyone!"

(Lincoln and Lily sit at the table where the others follow suit. Lynn Sr. comes in with fried fish.)

Leni: (notices Lily's hair) "Wow, Lily! Look at you!"

Lola: "Nice hairdo, sis!"

Luna: "You're really rockin' that new look, dudette!"

Lily: "Aw, thanks! It was Lincoln's idea."

Lincoln: "Oh, don't mention it."

(While everyone's eating dinner, Lincoln feels something touching his arm. He sees it's Lily's hand brushing up against him.)

Lincoln: "Oh, you…"

Lisa: (looks at Lily's clothes) "Did you really go out dressed like that?"

Lily: "Yep."

Lana: "Kinda see a bit of me in those threads, Lilster."

Lily: "Ha, same thing."

Luan: "So… What'd you two get caught up in out there?"

Lily: "We had fun at the park! We went on the swings, and Lincoln taught me how to play basketball!"

Lynn: "Oh, really? If I were there, I would've taught you everything you'd need to know."

Lincoln: "Ha! Luckily, I was there."

Luna: "Linc, you're really gonna dig what I'm dishing out tomorrow."

Lincoln: "Can't wait."

(After everyone's finished with their food, Lincoln and Lily go upstairs into the former's bedroom.)

Lincoln: "Let's do it!"

Lily: "Yeah!"

(The two quickly take their clothes off, as they immediately make out with each other and fondle their bodies. They lie on Lincoln's bed and continue to do so, until Lincoln's on top and Lily's at the bottom.)

Lily: "Put it in me!"

(Lincoln pokes his shaft at Lily's vagina, then shoves it past her lips and sinks all the way in, earning some moans from her.)

Lily: "Pound me deep!"

Lincoln: "Yeah, yeah!"

(Lily cups Lincoln's cheeks and plants kisses over his face.)

Lily: "You like my kisses?"

Lincoln: "Yeah, baby…"

(As Lincoln caresses Lily's breasts, he fucks her harder and deeper. Lincoln kisses Lily's mouth.)

Lincoln: "You like having your pussy pounded?"

Lily: "It feels awesome!"

(Lincoln moves his cock around to feel more of Lily. She holds Lincoln down to take more of her pussy, as she screams.)

Lily: "I'm cumming!"

(Lily's pussy squirts onto Lincoln's pubes. Moments later, Lincoln climaxes inside of Lily.)

Lincoln: "I'm cumming too!"

(Lincoln lays on Lily's body, as she hugs him.)

Lily: "I love you, big brother…"
