It was morning time, and Lincoln and Haiku were sleeping in the bed together, with Lincoln hugging her bulging muscles. As the suns rays casted on Lincoln, he slowly woke up and realized he was hugging Haiku. He was thinking about letting go and waking up for the day, but it was a summer day and he felt it was right to go back to sleep. Haiku eventually woke up at one moment but did the same thing Lincoln did as she fell back asleep.

Some time later, Lucy was at the door with Luan as they both crept up to Lincoln's door. Luan was giggling but Lucy had to shush her.

Lucy: Quiet Luan, you're gonna get us caught.

Luan: Sorry Lucy, it's just that, pfft, I can't believe Lincoln has a girlfriend. I never thought he would want one, and especially Haiku.

Lucy: Well keep down until we get that photo.

Luan nodded and covered her mouth as Lucy quietly opened the door. The rays had shined on Lucy and Luan as Luan had to cover her eyes as well while they made her way into the room. After they snuck in and closed the door, they crept over to Lincoln's bed. When Luan first spotted Lincoln and Haiku, she almost squealed until Lucy covered her mouth for her.

Luan(whispering): You never told me Haiku was so buff.

Lucy(whispering): I'd rather let you find out for yourself.

Lucy then took out her phone and climbed onto Lincoln's chair so she can get a good picture of him and Haiku sleeping. After she takes the photo, turning off the camera flash, she gets off of his chair and they leave the room quietly without waking them up. After they were out of the room, Lucy showed Luan the picture.

Luan: Aww, they look so cute together.^^

Lucy: I know. I'm going to keep this in my phone. Don't tell anyone, Okay?

Luan: Okay but send it to my phone as well. I wanna keep this cute moment too!

Lucy sends the photo to Luan's phone as they both go downstairs to get some breakfast. Around 9 AM in the morning, Lincoln and Haiku both woke up at the same time. As they yawned and rubbed their eyes, they both looked at each other before turning away and blushed at each other.

Lincoln: Oh uhh....Good Morning Haiku.

Haiku: Umm..... Good Morning Lincoln.

Lincoln got out of his bed first so that he could give Haiku some space. He then begins stretching as Haiku gets up out of his bed as well. She looked at Lincoln and blushed a little more, imagining if he was as big and as strong as her. Lincoln noticed her looking at him and blushing, which made him turn around and blush himself.

Lincoln: I-Is there something wrong Haiku?

Haiku noticed him and turned around herself.

Haiku: N-No Lincoln, nothing wrong.....

Haiku then went into a blushing frenzy as she ran out of Lincoln's and into Lisa's room, where Lisa was in as well. She had a few containers of the blue liquid that she drank yesterday. Lisa noticed Haiku and had stopped her experiment.

Lisa: Hello Haiku. Do you need anything from me?

Haiku: Actually yes, yes I do.

Haiku then blushes again as she thinks about Lincoln being buff again. She imagined him flexing his muscles for her, making her blush a lot. She imagined them two lifting weights together. She even imagined them at the beach, showing off their bodies together. As she was dreaming, Lisa was watching, intrigued by Haiku and by putting two and two together, she found out what Haiku wanted.

Lisa: Haiku, judging by you blushing and how you got so buff, I'm assuming you came in here to ask if I can give one of the serums to Lincoln. Is that correct?

Haiku stopped and was surprised at Lisa. How did Lisa know the exact reason why she came to her?

Haiku: How did you know?

Lisa: Lucky guess.

Lisa then takes one of the containers and hands it to Haiku, who carefully takes it from her so she won't break it.

Lisa: Let Lincoln drink the entire container like you drank the cup. I fixed t a bit so his muscle  growth should start after he finishes the container.

Haiku: Okay, and thank you Lisa.

Lisa: You're welcome.

Haiku smiled as she left Lisa's room and went back to Lincoln's room, where he was conviently sitting on his bed, reading comics. When he saw Haiku, he smiled and blushed again as he patted the seat next to him so Haiku could sit down. She nodded and indeed sat down next to him, the side of the bed that he was on had been lifted up from her weight.

Lincoln: Woah, almost forgot how heavy you were for a  second.

Haiku: Hehe, yeah. These muscles are pretty heavy.

She flexes a bicep to show him what she meant.

Lincoln: Yeah, I can tell. I am thirsty right now anyways. Can you go get a drink for me please?

Haiku: Already got one.

Haiku hands the drink to Lincoln. He didn't think they had a cup that looked like Lisa's container, but he didn't care anyways.

Lincoln: Thanks Haiku.

Lincoln drank the serum in one gulp. After he finished it, he sucked his teeth a little.

Lincoln: Tastes a little plain, I wonder...

Suddenly, he dropped the container and started groaning in pain. Haiku knew this was gonna happen so she got off the bed and stepped back to his door so she could give him some space to grow. Lincoln fell to the floor and started clutching his stomach.

Lincoln: Haiku.... what was in that drink?

Haiku: It wasn't a drink, it was Lisa's serum.

Lincoln: WHAT?!?!?!?!?!

But before Lincoln could say anymore, his arms and legs suddenly bulked up, much to his surprise. Haiku already was blushing as Lincoln was groaning and gaining muscle faster than she did. As his muscles were getting bigger, Haiku's blush was also getting bigger. He tried to balance himself by standing up, but that only caused his pecs to explode with power filling inside of them. This caused Haiku's face to become even more red.

Lincoln: Getting....so......big......can't.....control......it......

Pretty soon, he was so big the bed was pushing against the wall due to his size. Haiku was still near the door, wanting to give him all the space that he has but, because of the size of his room, that's very limited. Lincoln then did one last flex for his final growth sequence as his flex caused his pajama shirt to explode off of his body, leaving his now super ripped upperbody shown, which almost made Haiku's nose bleed. Unlike Haiku's dress, which was stretchable, Lincoln's wasn't, but luckily for him, his pajama pants survived. After his growth, he stopped and looked at himself in the mirror, confused and curious at how big he had grown. He was now as big as Haiku is.

Lincoln: Haiku, why did you give me Lisa's serum.

Lincoln turned around to look at her, only to find her in a blushing frenzy. He then realized why she even left the room overall.

Lincoln: You wanted me to grow just as big as you, didn't you? 

Haiku: Y-Yes I did. Are you upset at me?

Lincoln then turned back at his mirror to look at himself again. He raised his arm up in a bicep flex and looked at how much it swelled, much to his surprise.

Lincoln: I'm not upset, I like this new look! But how will I tell the others?

Suddenly, a knock came on the door. Haiku opened it to see Lisa at the door. She was in her usual attire, changing her clothes after Haiku left the room.

Lisa: Just here to check up on you. Did it work for Lincoln?

Haiku: Take a look for yourself.

Lisa went into the room to see Lincoln. As soon as she saw him, she blushed just as hard as Haiku did and came really close to bleeding from her nose as well. Lincoln noticed this and turned his face away, a little embarrassed that even his sister likes his new muscles. Thankfully for Lisa, she was small, so she was able to come inside the room to sit down and talk to both Lincoln and Haiku. Lisa went over to sit on the bed while Haiku and Lincoln stood in front of her. Them standing up basically limited the space in his room to zero.

Lisa: Lincoln, I only gave her that on her request. Don't be upset at anyone please.

Lincoln: I'm not upset at all, but it's gonna be hard explaining this to the family.

Lisa: Don't worry, I'll handle it. For now, how do you feel?

Lincoln: I feel like I've been working out for years.

Lincoln flexes his biceps, which rise to unreal proportions. Haiku flexes her biceps as well, revealing that they both are the same size. Lisa takes down mental notes in her head.

Lisa: I see, the serum works on both genders. It's a good thing I made more of the serum and that Haiku came to ask for one for you. I'm impressed, this experiment is a complete success!

Lincoln: Okay, now for one other question.

Lisa: And what's that?

Lincoln: How am I gonna get new clothes? My shirt bursted off of my body and my pants look like they'll do the same thing anytime soon.

Lisa: Hmm... I'll ask Leni if she can make some stretchable clothes for you.

Lincoln: Good. But should I even show myself to the others? What will they think about my new muscles?

Lincoln them flexed his pecs again, making Haiku and Lisa cover their noses and blushed again at the sight of his bulging pecs as he flexed them again.

Lisa: If you do go out and everyone sees you, their reaction will be just like ours. Only difference is, they probably won't be able to hold it in.

Haiku: Our best bet is for you to at least show yourself, but not flex. Flexing almost made us nosebleed. It be best if you at least didn't flex too much or show off your muscles that much towards them.

Lincoln: Alright then, let's get out of here before we accidentally break something then.

The other two nodded as they all left Lincoln's room, first Lisa, then Haiku and then Lincoln. Both Haiku and Lincoln had to duck their heads and turn sideways so they wouldn't hit the doorway. Today was gonna one helluva day for them!

(AN: Hey guys, Lion here! Chapter 2 is done and this time, Lincoln drank the serum, making him grow as big as Haiku. I made him buff as well to make it more fair so more people could read this. Lisa still has a couple of serums left, I wonder who she's gonna give it to next? Please put positive comments and vote as you please. Chapter 3 is gonna be quite a day for Lincoln and Haiku. Till then, Lion out!)
