"You're totally in love with him!" Cake declared as she knowingly leaned against one of the tree houses walls.

"I do not!" Fiona blushed. Cake could only smirk at the human female. The two playfully glared at each other before Cake stretched herself out to wrap her now long and thin body around Fiona.

"You looooove Prince Gummbbaaaaaaaallllll...~" the cat started to repeatedly sing.

"For the last time; I'm done with guys." Fiona stated irritably.

"Yeah- yeah., sure you are. Would you be 'done with guys' if Prince Gumball or Flame Prince showed up naked with a bouquet of roses demanding for your hand in marriage?" Cake said as she released Fiona. She flicked her tail up into the blushing humans face before walking to the kitchen. "Dayumn, that would be H.O.T!" Cake purred gleefully.

"Cake!" Fiona yelled as her cheeks burnt a bright red.

"Not my fault Flame and Gumball are hot as. See what I did there? Flame Prince... he's hot..." Cake grinned cheekily as she kept her back to Fiona while she searched the kitchen for an appropriate dinner dish.

"Yeah, I get it..." Fiona mumbled as she tried to cool her face down.

"Actually, I might go visit him tonight..." Cake declared a suggestive tone.

"I'm serious Cake! Shut up!" Fiona said as she took her green backpack off. She used it as a weapon then threw it across the room and against Cake's back. Cake started to laugh then turned around to face Fiona with a grin.

"I'm only playing. I do have to go out tonight though." Cake chuckled.

"Where?" Fiona asked as she prodded the wooden floor to retrieve her bag. It was as if the subject on who Fiona's potential lover would be was instantly dropped. Secretly Fiona wanted to keep discussing it because she wasn't all that sure on who she liked anyway.

"Out," Cake answered cautiously. Fiona raised an eyebrow and crossed her arms. "Out to see the bae..." Cake sighed happily. Fiona rolled her eyes then dropped her arms back to the sides of her body. The flicker of something shiny was quick to grab their attention. Fiona hadn't noticed a small vile had slipped out of her bag as she had picked it up. Cake was attracted to the pink, sparkly liquid that was inside. She grabbed it by outstretching her arm, staying in front of Fiona. She then held the vile up by Fiona's face and furrowed her little kitty eyebrows.

"What's this?" The cat suspiciously asked as she tapped one of her paws on the wooden floor boards. Fiona's face heated up in a blush again and reached for the glass container. Cake pulled it back and stretched her arm high above their heads. "It looks like a potion..."

"I-it's nothing- I swear." Fiona lied as she tried to jump up and reach the small glass vile. As she tried to jump higher, Cake would continue to outstretch her abnormal limb.

"Oh yeah? A mysterious sparkly potion is nothing?" Cake hummed as she lowered her arm. Fiona finally reached the glass vile and shoved it down her shirt and into her bra as soon as she got a hold of it.

"It's just a gift..." Fiona said softly. Cake gave her a look that the human knew meant she wanted more information. "...From the Magic Woman..." Fiona coyly confessed with hesitance. Fiona sighed softly then covered her chest with both her hands to make sure the cat wouldn't try to grab it out.

"Fiona!" Cake gasped. "We don't trust the Magic Woman!"

"Yeah- it's just this once. Plus I'm going to give it to someone else as a gift. I know giving away people's presents is pretty bad, but I guess it's more of a test then a gift when I give it away..." Fiona admitted.

"What're you going to do?" Cake asked as she carefully stared at Fiona.

"Don't worry so much Cake. I'm just gonna go into the Candy Kingdom for a bit though. Gumball called earlier for me to go on some 'private mission'." Fiona said with air quotes. "I'll be home before dinner." Fiona winked before she walked towards the exit.

"Woah-woah-woah! I don't think so." Cake yelled as her confusion continued to bubble.

"Love you~" Fiona blew the cat a kiss before she made her departure. Cake sighed, letting her confusion get the better of her. She decided Fiona was in fact a teenage, so weird behaviour like this was probably normal for her.

"Please... Just don't get into any trouble..." Cake sighed again.

The Candy Kingdom was large like usual. The streets smelt of a sickening sweet like scent that went through stages of enjoyment. At first the delectable sugary smells made you want to get down on your hands and knees and devour the streets. Then it moved into a stage of familiarity; you'd get used to the sweet smell and it was just something you would have to put up with. In Fiona's case, she had reached the stage where constantly being around the aroma of the Candy Kingdom almost made her sick to her stomach. Like if you binge eat chocolate for a solid three years then get sick of the flavour.

Fiona walked up the eatable stairs that led to the large castle that was central to the kingdom. She looked up at the Bubblegum Guards, noting that they looked the same as usual. She walked up to the large doors then carefully knocked on them. Fiona had always had this slight fear that one day she would knock so hard her fist would go through the door- or anything in the kingdom.

She knocked again, this time knocking a little harder than the first time. The door finally opened after a good few minutes of waiting. Fiona looked down to see Peppermint Maid smiling up at her.

"Hello Fiona. Here to see the prince I assume?" She said happily.

"That I am," Fiona grinned as she stuck both of her thumbs up. Peppermint Maid nodded then threw one of the doors open enough for Fiona to step through. Once Fiona was inside, the small candy maid closed the door behind them.

"He's down in the kitchen preparing some scones for the Candy People. Would you like me to lead you there?" The maid asked as she moved to walk beside Fiona.

"Oh, no, I should be fine. If I get lost I'll be sure to call out to you." Fiona smiled as she turned to walk in the direction of the kitchen.

"You can also call if you need anything, okay?" Peppermint Maid sweetly smiled.

"Okie-dokie" Fiona said cheerfully as she started to walk to the kitchen at a fast pace. She walked down a few halls and had to turn around some corners to get there. It was times like these where she was happy that everyone trusted her so much. After all, she was a greatly admired hero.

Fiona turned one more delicious pink hall to find the large doors that led into the kitchen. She opened up the doors to see Prince Gumball calmly mixing something in a large, pink mixing ball. Fiona naturally assumed you could eat everything that was in the kingdom, so she used a question that had been on her mind for a while to inform Gumball of her presence.

"Can you eat that bowl? Or the spoons? I mean- you can eat the streets and everything. So if you can eat the spoon, what happens when you eat cereal? Can you just eat the silverware when you're done?" Fiona queried. Gumball jolted a little then gave Fiona an alerted look.

"Oh- Fiona," he smiled with relief. "No, the silverware is made of steel. And the bowls are made of plastic. Not everything is eatable. You weren't thinking of trying, were you?" Prince Gumball gave Fiona a look of sudden concern.

"No silly," Fiona chuckled. "I was just curious." The human shrugged as she walked over to the prince.

"What brings you down into my kitchen on this fine day? You're top secret mission isn't until tomorrow..." Gumball questioned as he continued to stir his mixture. He gripped his wooden spoon a little looser as he looked at Fiona.

"I know; I just have a gift for you. I was going to buy more, but I need to test it first. It's this beautiful sweetener I was planning to use for Cake's birthday cake. You can just drink it without using it for any deserts, which is what makes it awesome. But I'm not sure if she'll like the flavour... So I was wondering if you would give it a taste test for me. You're like, a total pro when it comes to flavours and desert stuff..." Fiona smiled.

"Oh- are you sure? You could always taste it for yourself. Especially if you're baking it..."

"I don't like my judgments. I already had a taste, I thought it was delicious. I just need a second opinion..." Fiona smiled confidently. Gumball stopped stirring for a moment so he could stare at Fiona in thought. He then sighed and put the bowl down, resting the wooden mixing spoon on the edge of it.

"Alright, I'll give it a taste. Only a little sip though..." Prince Gumball decided. Fiona grinned then reached into her shirt. She had to feel around in her bra for a bit before she could pull out the vile. Gumball gave a her an uncomfortable look as the human girl pulled it out. "It looks like a potion..." He stated.

"I know! I bought it in a special container to make it look cooler..." Fiona smiled as she used her teeth to pull the cork out of the top of it.

"Why was it down your shirt?" Gumball asked hesitantly.

"I was trying to hide it from Cake..." there was slight truth to Fiona's answer. She was trying to hide it from Cake, but not for the same reasons Gumball was hopefully thinking. Gumball took the potion from Fiona's hand then sniffed it. He tried to recognise any untrustworthy scents. The Prince's suspicion was waking Fiona feel slightly nervous. She bit on her bottom lip as she eagerly watched Gumball move the vile to his lips. He tilted it back a little so that a few drops would fall into his mouth.

The flavour of the potion instantly danced on his tastebuds. He smiled at the taste the potion had. It tasted of the sweetest strawberries mixed with the yummiest sugary lollies and the best candies in the Land of Aaa. He licked his lips then looked at Fiona happily.

"It's fantastic! She'll love it for sure... Do you mind if I keep the rest? I can give you money to buy more..." Gumball said with a bashful grin.

"No, it's fine. You keep it. I just wanted to make sure it tasted good. I've gotta go get started on Cake's cake." Fiona grinned at the sound of the repeated words.

"Wonderful! I'll see you tomorrow for the mission, okay?" Prince Gumball smiled. Fiona nodded and turned around.

"See you then," she said with a cheerful smile as she left. To her surprise, her silly unplanned plan worked out better than expected.

Prince Gumball leaned against the kitchen counter and looked down at the vile. He checked to make sure Fiona was gone before he drank the rest of it. The flavour was very morish and lingered in Gumballs mouth. He wanted to have more of the liquid, but he didn't know where he could find any. Gumball sighed then looked back at where had been working, deciding that he would return to making the scones another day.

After he wrapped up his mixing bowl in cling wrap so he could come back to it, he completely abandoned the kitchen and headed up to his room. While he was walking, he looked down at his feet. He usually walked with his head held high, but at the moment his shoes were catching his attention. He crossed his arms over his chest then furrowed his eyebrows in thought.

He moved his tongue around the insides of his mouth, trying to get more of the flavour on his tongue. He licked his lips then looked up to see his bedroom door. He suddenly didn't feel right. His head grew heavier, just like his eyelids. His throat grew tight and his stomach started to twist and turn. Something inside of him started to feel wrong. His lips suddenly grew really dry as his vision started spinning. He became weak and dizzy.

Prince Gumball could barely open the door to his bedroom before he collapsed to the floor. His ears started to violently ring as his vision faded into pure blackness. Even through the back of his eyelids his head was still spinning rapidly. This feeling made Gumball want to throw up. Eventually he just gave into the unconscious state that was continually pulling at him.

❦ • ~ • ~ • • ~ • ~ • ❦

When Prince Gumball first opened his eyes, his vision was blurry and out of place. After he blinked a few times, he could see perfectly fine. His eyelids were heavy and the feeling of his sheets made him feel like he was being weighed down. Gumball slowly sat up and looked around his bedroom.

"When did I..." Gumball couldn't think properly. The only thing he could remember was standing in the castle kitchen baking scones. "I must've passed out while mixing..." Gumball sighed. The tingly flavour of the potion he had consumed was still in his mouth though. He opened and closed his mouth a few times, allowing his tongue to try and recognise the flavour. All he could remember about it was drinking something delicious that he was desperate to try again.

Gumball smiled when he decided he knew where he would find the flavour. He moved to the side of his large bed then stepped onto the floor. He weakly wobbled for a bit then changed out of the femininely coloured robes someone must have put him in. Prince Gumball's pink feet moved over the smooth floor. He almost tripped over while changing into some lazy attire. He decided on a simple pair of pants and a slightly baggy long sleeved shirt. He didn't care for his zombie like appearance. To him, the only thing that really mattered right now was getting more of that flavour on his tongue.

As soon as the prince left his chambers, Peppermint Maid was at his side. "How are you feeling your majesty?" She politely asked.

"A bit out of it. What do I have planned for today? If it's important, I don't care. Cancel all of it." Gumball commanded.

"You're supposed to be meeting up with Fiona, my prince. We had to cancel her meeting with you about the candy lizards because you were still asleep. She's been very worried about you." The maid stated. Gumball continued to walk down the hall as the peppermint tried to keep up with his fast but wobbly pace.

"I don't care," the response was slightly surprising for the maid. Gumball was the sort of prince who cared about anything and everything; especially Fiona. "How long had I been sleeping for?" Prince Gumball asked.

"A total of three days Sir..." Peppermint Maid answered.

"I'll be going out for a while. If there's an emergency, you know what to do..." Gumball said as he approached the large doors that led into the castles foyer. He walked through then stopped at the large front doors. "I'm not sure how long I will be gone for, but if anyone asks for me tell them I'm still asleep." Gumball said as he opened the door.

"But sir- I do not intend on being rude, but you look awful. Maybe you should go back to bed..." Peppermint Maid said with concern.

"Don't worry, I'm alright..." Gumball smiled weakly. "I'll be back soon..." and with that Gumball closed the doors behind him and started making his way to his desired destination. Peppermint Maid sighed then continued to her daily chores.

His current weak state was making it hard for him to walk around unnoticed. He tried to avoid talking to people, at least until he reached the large gates that surrounded and protected the Candy Kingdom. Prince Gumball safely got out and snuck between some trees, deciding to take the long route.

He hadn't been to Marshall Lee's house all that much. But he knew the vampire had the answer somewhere. He just had to. Everything in his body as leading him to the immortal king of the Nightosphere. For some reason, Marshall Lee was the only thing he could think about. All of his thoughts were like a long string that was tied around Marshall Lee. And every time he tried to not think about him, he would only be pulled right back into thoughts about Marshall. Gumball sighed as he continued to walk.

Prince Gumball eventually approached the large cave he could sense Marshall Lee's house was in. He knew it was in there, but his entire body suddenly got pumped with some sort of adrenaline from just knowing the vampire lived in the place he was so close too. His heart sped up at the thought of seeing the other male. Gumball felt too ill to worry about how stupid these thoughts were, and how irrational he was feeling. He just needed Marshall, and he needed that flavour now.

Gumball walked his pink little self up the small stairs and over the cute patio. He politely knocked on Marshall Lee's door and waited for an answer. Marshall carefully peeked through his crappy curtains to see the Prince patiently waiting. He wondered why him, of all people, would be knocking on his door. Especially so early in the morning. Marshall sighed then hovered to his door, slowly pulling it open.

"What brings the prince of adorable people I want to sink my fangs into here on this fine morning?" Marshall Lee causally asked.

"I need to taste you," Gumball said with desperation leaking from his voice. Marshall was taken aback with the sudden command. He looked over Prince Gumball's body, realising the prince was in bad shape.

"Dude, you don't look good. Maybe you should go home..." Marshall Lee said softly as he carefully landed on the ground so he could slowly take a few steps back. Gumball took this as an invitation to enter his dimly lit house.

"Please let me have a quick taste..." Gumball said softly.

"A taste of what? You're acting really weird... Want me to help you get home?" Marshall asked as he stepped away from the advancing Prince. Gumball continued to walk closer to him, making both of them walk further into Marshall Lee's cosy house. The sound of their feet touching the carpet was nothing compared to Gumballs heavy pants. There was so much need in his face that Marshall sighed and stopped walking.

"I need to taste you..." Gumball said in a voice that was just over the sound of a whisper.

"As long as you get lost afterwards, feel free to taste as much as you like," Marshall shrugged as he held his arms out. Prince Gumballs body bubbled up with excitement as he stepped forwards, wrapping his arms around the lower half of Marshall Lee's body. Marshall's body froze at the sudden contact. He then tried to not shove Gumball away as the feeling of the prince's warm lips touched his neck.

To Marshall, it was slightly ironic that Gumball was licking his neck. Prince Gumballs lips were pursed for a moment, giving Marshall Lee's skin a chaste kiss before he widened his mouth enough to properly taste his neck. Marshall Lee helped Gumball by moving his hair away from his neck for him. He moved the black strands, which gave Gumball more room to roam his lips.

Marshall closed his eyes, finding he was slightly drawn to the feeling of Gumballs mouth finally touching him. Marshall Lee tilted his head to the side to allow Gumball more access to his neck. Gumball moved towards the crook of Marshall Lee's neck then let his lips move up the side of it. Gumball started to suck around the area that connected the lower parts of Marshall Lee's pointy ear to his pale skinned body.

Marshall's lips slightly trembled as Gumball slowly started to move along his jaw line. To gumball, the flavour of Marshall Lee's skin was better then he imagined. He thought the strawberry stuff that was in the glass vile was heavenly and out of this world. But Marshall was over a thousand times better. His skin was bittersweet, and all Gumball could think about was how he wanted as much of it as possible. He wanted to have all of Marshall, and never give it away. Gumball wanted to infinitely taste the vampire.

Marshall shook his head, trying to rid himself of the pleasurable feeling he got from Prince Gumball touching such a sensitive area. He abruptly shoved the prince away from him.

"You have to stop~ whatever it is you're doing. This is freaking weird..." Marshall said coldly. Gumball's eyes widened as he slowly placed his hand over his lips. He stared at Marshall Lee for a moment before he finally spoke from behind his hand.

"I'm so sorry... Marshall... We've known each other for a really long time... Haven't we?" Gumball said as he slowly lowered his hand.

"What are you getting at?" Marshall asked as a deep blush covered his face. He knew exactly what Gumball was talking about; he could hear it in the tone of his voice plus the situation residing in his pants.

"Let's put our differences aside for a moment. Clearly we're both attracted to one another. We probably haven't had any sort of sexual release for a while... so why don't we give it a shot? Just this once..." Prince Gumball shyly suggested. Marshall stared at the pink Prince for a moment, trying to decide on the proper response. "You also said I could taste as much of you as I want..."

"Fucking hell," Marshall growled as he stepped forwards and grabbed Gumball by his arm. "I've been waiting way too long for this day." Marshall Lee stated as he pulled Gumball towards the ladder that led up to the bedroom that the vampire hardly ever used.

Gumball was thrown down onto the bed, which resulted in him making a squeak like noise out of surprise. Marshall chuckled softly as he hovered over the prince's pink body. "Do you have any idea how long I've been waiting for you to come into my house to say that..." Marshall said in a soft voice. Gumball could hear how nervous Marshall Lee actually was. It was as if his cool and collected demeanour refused to become a part of his show.

"Marshall..." Gumball said softly. Gumball sat up and wrapped his arms around Marshall Lee's neck, drawing the vampire closer to him. He took a moment to take in the vampires scent. Marshall did the same with Gumball; loving how sweet and sugary he smelt. This made Marshall Lee wonder about what the Gumball Prince tasted of. He tried to move slowly to not scare the prince.

Marshall lowered Gumball back down onto the bed. Gumball watched Marshall carefully, each movement only further peeking at his interest. Marshall Lee's hands shakily held onto Gumballs shirt. He was going to remove it. He was going to take it off. He thought about how easy it would be to undress the man of his unsleeping dreams. He thought about just ripping it away from his body. But Marshalls hands could only remain pressed into the soft material. Prince Gumball started to grow desperate. He desired the touch of the vampire, and he was getting irritated with how long it was taking for him to get it.

"Marshall, you can touch me..." Gumball assured him. Marshall slowly moved his eyes away from Gumballs shirt so that he could look the prince in the eyes.

"Are you sure you want to do this? I mean, I can't wait any longer for you... And I don't know what I'd do if you didn't want this as much as I do..." Marshall said in a small, bashful voice.

"Stop talking nonsense. I want you really badly..." Gumball shamelessly admitted. He spread his body out and then grabbed at Marshall. He wrapped his whole body around Marshall, pressing both of their bodies tightly together. "Marshall, I need you so bad right now..." Gumball panted.
