Author's Note: Hullo, AngelRosemary here. Alright, so you've probably seen from the summary that this is a Princess Bubblegum and Marceline friendship story. (No romance.) This is, once again, in continuation of previous stories. In case you haven't been following me, here's what you need to know:

When Finn turned 18, Marceline turned him into a vampire. They are currently together.

They had a son named Benjamin, who is about 15 by now. (He was inspired by ilikekorn.)

This story's plot was inspired by a story by iLynxen. (Yes, I got permission.) This story goes out to iLynxen. Be sure to check out some of iLynxen's stories, too.

With no further ado, enjoy the first chapter. And remember, every time you review, a sex elf gets his first sword. :D

Warning: Slight out-of-character Princess Bubblegum, but I have an excuse.

"Wow, that was algebraic!"

"You said it, dad. Mathematical!"

"Rhombus!"

The trio laughed. They continued their trek to the Candy Kingdom. Finn took off his charred hat to examine. "Man, that electric gorilla didn't go down easy."

Benjamin was grinning from ear to ear. "Yeah, but we schooled that playa monkey style! You know what I'm saying?"

Marceline frowned. "Wait, what?"

They all laughed again as they walked onto the Castle grounds. Benjamin frowned and looked to Finn. "Hey, dad, how come Uncle Jake and Aunt Rainicorn didn't come with us?"

He shrugged. "They must not have slept well last night. I went by their place and knocked on their bedroom door, but Jake started yelling at me."

Marceline smirked and rolled her eyes. "Right. Hey, Benny, how would you like some new little cousins?"

"What?"

"Nothing, Finn."

They entered the foyer. Finn screamed, "YO, PRINCESS! WHERE ARE YOU GIRLFRIEND?!"

Peppermint Butler came running in. "Finn, why in the world are you shouting?!" He looked accusingly at Marceline. "Was your lady friend giving you trouble again?"

Marceline stared at him. "Excuse me, what's that supposed to mean?"

Benjamin quickly stepped between them. "So, Pep But, do you know where Aunt Bonnie is?"

He waved his hand to the right. "Oh, she's just in her lab again, working on something. She seemed very busy last time I checked on her. I wouldn't recommend bothering-" They were speeding in that direction before he could finish his sentence.

They found Princess Bubblegum standing at a table, a test tube of liquid in each hand. Her hair was tied back and her eyes were droopy. She gave them a weary smile. "Oh, hey guys, what's up?"

"Hey, Princess," Finn said with a grin. "We just came by to tell you that the electric gorilla has been taken care of."

"Yeah," Benjamin chimed in. "We tied him up with power cords and sent him off to the Charge Kingdom, just like you said."

She nodded. "Excellent, I knew that I could count on you guys."

Marceline frowned and floated closer to the Princess. "Man, Bonnie, you look terrible."

She shrugged. "Oh, I'm fine. I just haven't slept for 41 hours."

Marceline's eyes widened. "Uh, do you need me to carry you to your room?"

She laughed sleepily. "Oh, no, I'm fine. I've gone for longer periods without sleeping. I'm fine, I'm used to this."

Finn nodded knowingly. He often saw Princess Bubblegum experimenting in a sleep-deprived state, so this was normal to him. "So, ah, what are you working on PB?"

She looked up and stared at him. Several moments passed. She blinked. "I don't remember."

Finn sighed. "OK, I'm going to take you to your room now, all right?"

She continued to stare blankly at him as he approached her. He scooped her up in his arms and started toward the door. Before he could leave with her, she held up her hand in front of his face. "Aye, mas despacio senorita."

Finn stopped. "Huh?"

The Princess giggled softly. "Ha, just kidding, but seriously." She looked over his shoulder at Marceline. "Hey, I think I remember what I was working on."

Marceline cocked her head slightly. "Do tell."

"Yes, I remember now. I made it for you. It will help speed the growth of your breasts."

Marceline stared at Princess Bubblegum. Her mouth hung open.

Finn turned a shade of red that Marceline would've made a nice snack out of, if she wasn't so distracted.

Benjamin tilted his head. "I don't get it."

Marceline shook her head. "What are you implying, Princess?"

The Princess giggled again. "Oh, nothing, Marcy. I just wanted to make something for you to use. Feel free to take a sip from the red test tube while I'm gone."

She smiled drunkenly at Finn, who still looked incredibly embarrassed. "Well sugar, are you going to take me to bed or not?"

Now Finn looked like his face was going to explode, it was so red. He glanced at Marceline and grimaced under her annoyed glare. He shrugged and mouthed "Sorry" before leaving with Princess Bubblegum in his arms. Marceline and Benjamin heard her cackle wildly and yell, "GIDDY-UP, FINNY, RIDE THEM COWBOY!"

Marceline grumbled, "Who does she think she is? My bust must be bigger than hers."

Benjamin stroked Marceline's arm. "It's all right, mom. Aunt Bonnie is just tired…or on drugs…or both."

Marceline grunted. She picked up one of the vials, the one of red, fizzing liquid. Benjamin gasped, horrified. "Mom, you're not going to really drink that, are you?"

She smiled sheepishly and shrugged. Tilting her head up, she swallowed the entirety of the solution. She placed the bottle back on the table and looked down. "Well, do you see any difference?"

Benjamin groaned and covered his eyes. "Do I really have to answer that?"

She shrugged again. "Oh well, let's go get your dad."

They floated out of the laboratory and up a flight of stairs to the Princess' bedroom. Finn stood by Princess Bubblegum's bedside. They hovered at his side. Marceline whispered impatiently, "Hey, man, are you almost done here?"

"Yeah, I was just waiting for her to fall asleep." The Princess lay on her back, quietly breathing in rhythm. He smiled, his eyes still glued to her.

Marceline pursed her lips. She grabbed Finn by the ear and pulled his face around to face her. "Hello, one and only sexy vampire queen right here."

His eyes widened when he saw her. "Uh, Marcy, did you happen to take that formula that Princess Bubblegum was talking about?"

She gave him a toothy smile and looked down excitedly. "Why, is it finally taking effect?"

Benjamin stared at her too. "It looks like something took effect."

Marceline growled. "What?! Glob it, Bonnie, they got smaller! I'm going to kill her for this when she wakes up!" She subconsciously planted her feet on the ground.

"Mom…" Benjamin planted his feet next to her. She realized with horror that they were the same height.
