(As Lincoln said that, it cuts back to the Loud House where the girls are having breakfast.)

Leni: "Does anybody know where Lincoln went? I haven't seen him all morning."

Lola: "He stepped out earlier."

Lisa: "Well, where is he, then?"

Lola: "No idea. He might be somewhere in town."

Lori: "Hmm… You know what? Lincoln can have the day away from us. We don't necessarily have to depend on him. We can always invite some of our friends over for some fun…"

Luan: "Yeah, that's a good idea!"

Lana: (to Lisa) "How much of that adult juice you got, sis?"

Lisa: "I got lots of them with me. Large quantities."

Luna: "Alright! Time to party, dudettes!"

Leni: "Yeah!"

(The Loud sisters begin to call their friends over to their house for a large summer sex-fest.)

Lori: "Hey, Bobby Boo-Boo Bear! Want to come over later today?"

Bobby: "I'll see what I can do after my shift, babe…"

Leni: "Hey, Chaz, Miguel. Wanna come to my place for a bit?"

Chaz: "I'll see after work."

Miguel: "Same here."

Luna: "Sully, Sam, wanna hang and get some practice in?"

(As the girls all invite their male friends for a good time, it cuts to Lincoln exiting Mrs. Johnson's house with kiss marks all over his face.)

Lincoln: "That was such an amazing tutoring session…" (looks at the clock) "It's only 1:45 PM, so it's off to somewhere else in Royal Woods."

(Lincoln heads into town to find somewhere. He looks down to see a dollar on the ground.)

Lincoln: "Oh, a dollar!"

(Lincoln bends down to grab the dollar. But when he bends back up, his head bumps into the backside of a familiar busty woman.)

Belle: (yelps) "Who's back there?"

Lincoln: "Look… I'm sorry. ma'am! I was just-"

Belle: "Get fresh with me, will you?! (turns around) "Wait… Lincoln?" (lifts up and hugs him) "Whatcha doin' in town, cutie pie?"

Lincoln: "Just enjoying the first day of Summer and enjoying it with some hot girls."

Belle: "That sounds like you. (giggles) "Say, I have the day off, and I'm planning on heading to the beach. You wanna come with me?"

Lincoln: "Wish I could, but I don't have my trunks with me."

Belle: "Don't worry. The beach's gift shop got some."

Lincoln: "Alright. How soon are we going?"

Belle: "I guess we can go right now."

Lincoln: "Sweet! Man, the girls are missing out!"

(Lincoln and Belle begin on the path to the beach. Speaking of the girls, a few of their male friends arrived at the house.)

Lola: "Winston! You made it!"

Winston: "Yeah, what'd you invite me here for?"

Chaz & Miguel: "Hey, Leni!"

Leni: "Hey, guys! I can't wait for the fun we're gonna have!"

(Soon, more of the girls' friends, Bobby, Silas, Sully, Sam, Benny, Francisco, Skippy, and David all arrived at the house. Lisa comes downstairs with several vials in her hands.)

Lisa: "Greetings, everyone. You're probably pondering about why we've summoned you here."

Bobby: "Yeah, I had to leave the mercado early to get here."

Lisa: "There's something that we need to tell you guys before the festivities happen…"

TEN MINUTES LATER…

(Everyone, sans Bobby and Benny, are all surprised at this revelation.)

Lisa: "Before we can begin, all of you must promise to never disclose any of this information to anyone else. Understand?"

(All of the guys nod in agreement.)

Lori: "Let's begin. First off, get those pesky clothes off. Otherwise, those serums will ruin them."

(The boys all remove their clothes until they're naked as the girls do the same.)

Luna: "Bottoms up, dudettes."

(The girls all drink their aging serums, the serum begin to take effect. Their bodies become larger and sexy, their butts and boobs become bigger, and their hair grows longer. The boys all look in awe.)

Lori: "Like what you see, boys? Now, it's your turn."

(The boys consume the aging serum, then undergo the mixture's bodily effects. Growing taller, with more developed muscles and privates, the guys are now physically adults.)

Lynn: "So… What do you think of yourselves right now?"

Silas: "I feel... Amazing."

Chaz: "Wow… I'm not fat anymore…"

David: "Astronomical."

Lisa: "I'll say…" (walks towards David and feels around his muscles) "I can't wait for the experimentation we're gonna do..." (giggles)

(As Lisa strokes David's cock, he kneads her buttcheeks and makes out with her.)

Lola: "You mind coming with me, Winston?"

Winston: "Sure."

(Lola takes Winston upstairs to her bedroom.)

Lola: "Time to try out that royal scepter of yours."

(Winston sits on Lola's bed while she gets on her knees and gives him a hands free blowjob. She plants her hands on Winston's knees as she goes deeper.)

Winston: "Oh, yeah…"

Lola: (muffles) "This tastes so good…"

(Lola pulls away, then slaps Winston's cock against her breasts. Next, she titfucks Winston's log as he rolls his eyes. Lori and Leni's room, Bobby is eating Lori's pussy while she's sitting on the vanity.)

Lori: "Oh, fuck! I missed you so much, booboo bear!"

Bobby: "It's been way too long, babe!"

(Bobby sucks on Lori's tits and shoves his cock into her snatch.)

Lori: "OH, FUCK! BOBBY!"

(On Leni's bed, Chaz is fucking Leni's asshole while she's sucking Miguel's cock.)

Chaz "Oh, yes! This feels amazing!"

Miguel: "Oh, hell yeah! Keep sucking!"

(Meanwhile, at Royal Woods Beach, Lincoln and Belle are strolling through the boardwalk.)

Belle: "Okay, honey, let's get you some trunks."

Lincoln: "Okay." (wipes sweat) "Damn, it's hot out here."

(At the gift shop, the two are looking through action mens swimwear. Lincoln looks at a pair of orange and white trunks while Belle glances at an orange speedo.)

Belle: "Lincoln, this could look great on you…" (grabs speedo)

Lincoln: "I dunno… Heard those things are really tight. Besides, I like these more." (grabs trunks)

Belle: (furrows eyebrows) "Hmph… We'll see about that, mister…"

(Lincoln's near the changing stall with the two pieces of beachwear in hand, and Belle standing by him.)

Belle: "Come on, Lincoln… Can you at least try on that speedo? For me?"

Lincoln: "Okay, sure."

(Lincoln goes in to put on the speedo, as he steps out of the changing stall.)

Lincoln: "Damn, these things are tight as hell."

Belle: "But all the girls get a chance to see that great big log of yours…" (giggles)

(Lincoln growls.)

Belle: "Lighten up, dear. Just wanted to see how you looked in them. You can take them off now."

Lincoln: "Okay."

(Lincoln returns to remove the speedo and switches to the trunks. He comes out.)

Belle: "Wow, those look great, too!"

Lincoln: "They feel way better. So much more comfortable."

Belle: "I'll buy those for you. And don't worry, I brought my own swimsuit."

(Belle pays for Lincoln's trunks, then she uses the stall to change.)

Lincoln: (in his mind) "Hope she chose something really sexy..."

(Belle comes out in a yellow strapless one-piece swimsuit. Lincoln eyes at her cleavage as she poses for Lincoln.)

Belle: "What do you think? I live up to your expectations, Mr. Loud?" (giggles)

Lincoln: "Yeah… You look so hot."

Belle: "Thank you. C'mon, let's enjoy the beach."

(Lincoln and Belle exit the store as they head to the beach. Belle tosses a beach chair and a towel in a spot. Belle lays on her stomach on the towel.)

Belle: "Oh, Lincoln… Could you rub some sunscreen on my back, hon?"

Lincoln: "Of course."

(Lincoln takes the sunscreen from Belle's bag and applies some on her back as he rubs it.)

Belle: "There you go. Rub it all over my back."

(Lincoln decides to get her shoulders too, but his bulge ends up pushing against her ass.)

Belle: "Mmm… I feel something poking down below…"

(A confused Lincoln and sees what Belle means, then blushes.)

Belle: "Can you get down there too, baby?"

Lincoln: "Uh… Sure thing."

(Lincoln lathers up and firmly kneads Belle's buttocks as she moans.)

Belle: "There you go… Just like that, Linky…"

(Lincoln finishes with another layer of sunscreen, as Belle gets up.)

Belle: "Now, it's your turn for sunscreen."

(Lincoln on the towel as Belle apples sunscreen on his back.)

Lincoln: "Man, that is cold."

Belle: "If you don't have it, you're gonna get sunburn."

Lincoln: "Fair point."

(Belle finishes rubbing sunscreen on Lincoln's back, he gets up, as Belle notices his hardened bulge.)

Belle: "Wow, it's even trying to burst out those shorts on."

Lincoln: "Yeah, it is."

Belle: "I can help you with that." (takes Lincoln's hand) "Here, come with me."

(Belle guides Lincoln to one of those closet rooms on the border. She takes a look around, certain that the coast is clear. She opens the door, as she and Lincoln goes into the closet.)

Belle: "Have a seat and pull those trunks down."

(Lincoln does as Belle instructed.)

Belle: "Don't want to get this baby dirty…"

(Belle pulls her swimsuit off and tosses it on the floor.)

Belle: (kneels in front of Lincoln) "Just sit there and relax… I'll take good care of you."

(Belle grips Lincoln's knees as she sucks on Lincoln's cock. He bites his lip as Belle gives him a satisfying hands free blowjob.)

Lincoln: "Your mouth's so warm and soothing…"

(Belle goes even deeper on Lincoln's log then she squeezes his balls. Lincoln moans in joy as he rubs his hands on her arms back and forth.)

Lincoln: "Ooh, I can already feel the nut coming…"

(Lincoln shoots his load into Belle's throat as the cum travels down to her stomach. She pulls off as she kisses the tip of Lincoln's log.)

Belle: "Hmm… Your cock's still hard. I'm gonna have to go with Plan B."

(Belle sits on Lincoln's lap as she lowers herself onto his cock, easing it into her pussy. He grabs her hips as he pounds her up and down. She grips Lincoln's shoulders as she kisses him.)

Belle: "You're lucky I'm doing this for you, Linky…"

Lincoln: "You're the best, Belle! I'm lucky enough to know a gal like you in the first place! Good thing you came over to babysit."

Belle: (giggles) "Hey, it was you that put the moves on me with that signature Lincoln charm…"

Lincoln: "Aw, it was nothing… I want that pussy deeper on my log..."

Belle: "Oh, you want the womb experience? Coming right up, Lincoln!"

(Lincoln pushes Belle further down on his lap, as she screams out in pleasure. He then makes out with her while fondling her buttcheeks.)

Belle: (groans) "Gonna squirt any moment now!"

Lincoln: "Same here! I gotta shoot!"

(The two ejaculate within seconds of each other, as their combined semen overflow from their conjoined privates. When Belle lifts her rear up, cum leaks out of her pussy and paints Lincoln's groin, which is still squirting small streams of cum.)

Lincoln: "Alright, my dick shouldn't poke through my trunks anymore. But now it's really messy."

Belle: "Don't worry. Lemme help with that."

(Belle licks the excess cum off Lincoln's log. He returns the favor by eating her pussy clean.)

Lincoln: "Wanna head back to our spot?"

Belle: "Gladly…"

(Lincoln and Belle return to their spot, as they soak up some sun rays.)
