"Doop-da-doo, dum-da-dum-dum..." Gumball sang while taking a shower in Fionna and Cake's house. He had been taking a vacation at their house, to take a break from the stress and restlessness of his princely duties.

"Hey, PG! You almost done in there?" Cake said through the door.

"Yeah, just a bit!" He replied, turning the shower knob to the right.

"Okay, hurry up then! You're gonna miss out on Bacon-Pancakes!" Cake walked away humming the Bacon-Pancake song.

Gumball opened the shower curtains and walked out if the tub, then dried off his gummy hair with a towel, and dried the rest of his body. He opened his pink duffel bag, pulled out some red boxers, and put them on.

Hmm... These feel okay. He thought to himself, in front of a mirror as he turned his body. It kind of exaggerates my butt though. He reached in his duffel bag again for a white button-up shirt, with a baby-blue collar. He put that on and examined how he looked in them as well.

"Hey Fionna, I know your in the middle of planning how your gonna kiss Gumball, but I need something red..." Marshall Lee just walked in casually.

"MARSHALL!" Gumball quickly pulled the shower curtain to cover up his body. "What are you doing here?!" His face faded to a hot pink.

Marshall Lee barely even look surprised. "Oh. It's you... Well, I just need something red." Marshall Lee asked. Gumball stopped think for a moment. Oh glob... I'm wearing red boxers. I cannot let him see them under any circumstance. Gumball knows from experience, that Marshall Lee would devour anything red.

Gumball was very worried. What if he saw them? "Well, e-excuse me, b-but I think you should knock before you enter a b-bathroom!" Gumball was both embarrassed and annoyed.

"Oh, were are my manners?" He bowed down, "I am so sorry I have disturbed you, my highness." Marshall Lee said mockingly. The Vampire King laughed. "Seriously, do have anything red? I haven't had anything for days."

Gumball knew he was just messing around, but that really pushed his buttons. "Really? Are you just going to shrug off the fact that you could of saw me stark-naked?!" He let go of the curtain and started to rant about how rude and ignorant Marshall Lee was. Soon, he realized that Marshall Lee was staring at him oddly.

Gumball realized that his red boxers were in the wide open, and of all times, he happened to have an erection, which was very visible.

Gumball, who is now shaking, decided to try and compromise. "Marshall Lee, we can just go and get some fruit from inside. You don't have to-" Marshall Lee pushed him to the wall before Gumball had a chance to finish speaking. Gumball yelped, and Marshall Lee smirked.

"Sorry Gumball, I'm just very... Thirsty." He said very sexually. Gumball was about to protest, but the vampire had grabbed the bulge in his boxers. "And it seems you are too..."

Gumball's face had turned to crimson. "M-marshall Lee... Please d-don't do this..." Gumball pleaded. Marshall Lee completely ignored him, and he got closer and closer to his face. He was about to press his lips against Gumball's, when he came up with something better. He slowly got lower until his face was near the bulge Gumball's boxers. He licked at it first, and Gumball groaned.

"M-marshall... s-stop..." He pleaded again.

"Stop? Why would I do that? You're obviously enjoying this." He came back up to his face. "Io need your sugar." Gumball shivered. He had never seen Marshall Lee act like this.

"Bacon-Pancake attack!" Cake barged in and threw the Bacon-Pancake at Marshal Lee and it hit the side of his head. "PG, are you okay? I heard you yell and..." She came to realize they had been doing, and threw the pan away.

"Cake, I promise this is not what it looks like." Gumball pushed Marshal Lee away.

"U-Uh... I didn't do that." She said nervously. Gumball quickly ran to the door and shut it and started freaking out. "Marshall Lee! Why did you do that?! You could of given Cake the wrong idea and..." He started to rant to himself again. But, Marshall Lee just stared at his boxers again. With the Bacon-Pancake still stuck to his head. "Oh, for the glob's sake!" Gumball had walked over to Marshal Lee and pressed his thumb down on his pressure point, which was on his shoulder. This snapped Marshal Lee back to his normal self. He then grabbed the pancake and threw it out the window.

"Finally! As I was saying..." Gumball started mumbling to himself, again. Marshall Lee yawned and looked at his wrist. He waited for a bit, then brought up food again.

"Well, I should go have some breakfast. You wanna come?" He said.

"Are you...? Ugh! ...Fine." Gumball had given up on trying to lecture The Vampire King. Gumball had put one some pink jeans, and walked with Marshall Lee to the main room of the tree house. Fionna had woken up and waited at the table.

"Yo, PG! Are you okay? I heard Cake had to help you." Fionna said. Cake looked over at them. She pretended to zip her mouth.

"Oh, well this guy over here, just gave me a little fright." Gumball patted Marshall Lee's back, hard. He was very mad at Marshall Lee, who rolled his eyes, and slid in on the long seat with Fionna.

"So, Fi. I see you weren't 'practicing' this morning?" He smirked. Fionna knew what he was talking about.

"N-no! I told you, I don't do that anymore!" Fionna said nervously.

"You don't do what, anymore?" Gumball inquired.

"It's nothing!" She pointed at Cake. "Hey look, Cake's done!" Fionna tried to get off the topic.

"Bacon-Pancake for you, Bacon-Pancake for you, Bacon-Pancake for me, and red fruits for you!" Cake said, as if she were working at a pancake house. "Everyone dig in!"

Fionna grabbed the syrup bottle and squeezed it. Nothing came out. She tried again, but the cap flew off. All of the syrup squirted on to her pajamas. "Aw, butts. I'm gonna go change." Fionna stuck her arms out and walked to the bathroom.

Now it was just Gumball, Cake, and Marshall Lee. It was completely silent. Cake sat in front of Gumball, and they just stared at each other, awkwardly. Gumball couldn't help but blush.

Marshall Lee stuck his fangs in a strawberry, and sucked the red color out of it. "Hmm... This doesn't taste as good as Gumball..." Cake and Gumball looked at him in shock. Did he really just say that?

Gumball decided to just end his vacation right then and there. He wasn't comfortable with the situation at all. "Well, I think it's about time for me to go back to the Candy Kingdom. Cake, please tell Fionna I had an amazing time, and forget about anything that happened today." Gumball went to grab his duffel bag and went down the ladders to get out of the house. He called Monochromicorn and got on him, then took of into the air.

Monochromicorn noticed that Gumball was pensive. "Prince Gumball, is something bothering you?" Monochromicorn said to him in Korean.

"What? Of course not... It's nothing, I'm fine." Gumball's face warmed and faded into a hot pink.

"Sir, your blushing."

"N-no I'm not. I'm just... frustrated with someone at the moment."

"Okay, whatever you say, prince."

It was about 8:30 now. Gumball would've been asleep by now, but he couldn't fall asleep. Whenever he lied in bed, he thought about the Red Boxers. He looked over at it for the 10th time. Trying it on once wouldn't hurt, right? He took the Red Boxers from a drawer, and changed into it. It still felt warm from earlier in the day. He looked at the mirror. This actually feels comfortable... I should wear these more often.

He kept on observing, then he heard the door creak open. He looked over at the door. It was slightly opened. It's probably just the wind. He looked back at the mirror, and sighed.

"Damn, those boxers really make your ass look good..." Gumball tensed up. He looked behind him and there he was. The Vampire King.
