(EDIT: MORE PAGES!)October 2023 Sketches 12 - Marshall Lee n Gary Prince (Adventure Time: Fionna and Cake)(Comic) (Patreon)

EDIT: Decided to add 5 more pages to fix the transition between some of the pages. Hope you like it!

Here's a comic featuring Marshall Lee and Gary Prince from Adventure Time: Fionna and Cake. The idea was suggested by both ds and HyperCole. I might have taken some liberties.

"Marshall and Gary go trick or treating , Marshall as a vampire and Gary as a prince. However it seems that choosing those particular costumes activated some old magic of their world as each time they receive candies they seem to get bigger, this quickly becomes a competition to see who can outgrow the other. / I noticed youve seen the new Fionna and Cake series, so I'd think itd be cute to see something with Gary and Marshall's human designs! Maybe something like Marshall helps Gary bake halloween themed pastries, but he accidentally bought some growth ingredient and both of them grow. Doesnt have to be huge really, but just something cute with them is nice!"

1.  Both Marshall and Gary are out Trick or Treating, Marshall dressed as a vampire, and Gary as a prince. THey've been pretty successful with how people really like their outfits together.

2. Both of them decide to enjoy the fruit of their trick or treating, and spend their time sitting at the park's fountain. Something off happened while they were eating, even though they were too focused eating and talking. Something about their outfits looking a little too similar to their previous, magic selves, made the statue of the fountain react, making it shift into a strange form for  a few seconds. As it shifted, it let out a pink mist, which slowly lowered towards the two boys. As the mist got into their bodies, they went into some kind of trance. As they did, their bodies started shaking...and BOOM, their muscles expanded.

The moment their bodies shifted in shape, they snapped out of the trance. THey looked at each other, weirded out at what just happened...until Marshall suggested to keep on trick or treating to get their minds off that.

3. Seems like the mist that got into their bodies has some kind of reaction with the candy they eat, as each time they trick or treated, and ate their candy, they kept on growing bigger! People became more confused, at both how their costumes were becoming too tight, or destroyed by their growing bodies to be recognizeable, or also these two hulking young men going trick or treating all playfully...while looking that they could perfectly tear up people's places into pieces;;

4. Seems like they ran out of houses to trick or treat...they either already passed through some homes, or some of the ones that they havent gone through were too freaked out by the two towering muscle men...didn't help that Marshall gave them a certain look whenever they refused to give them candy.

Marshall still seemed pretty hungry, so Gary was trying to figure out a way to get more candy...Meanwhile, Marshall noticed a group of trick or treaters that had a big haul of candy from their adventures...Perfect~ Marshall rushed towards them, and somehow, made one of the scariest faces he's ever done, even though it felt really natural for him in that moment...

The trick or treaters dropped their bags full of candy, and scrambled away from they intimidating monster boy. Marshall picked up his stolen loot, and shoved it all into his mouth! Making him grow even bigger with each piece of candy he ate!

5. While Marshall was going through a gluttonous rampage stealing a bunch of candy from trick or treaters that were passing by, expanding even bigger with each successfully stolen bag of candy, making both trick or treaters and regular passerby people scramble away in fear...Gary started to get weird memories as if he was able to create candy on his own!

He forcused on his hand for some time...and Poof! A piece of candy appeared! This is going to come quite handy for this occassion...

6. Marshall sat and leaned on one of the nearby buildings, treating the streets as if they were his own home, making himself comfortable. Letting out a monstrous belch, he patted his belly in satisfaction, and was ready to relax...Until some loud "thuds" started to come to his location...and the moonlight seemed to be eclipsed by something. He opened his eyes, and got shocked at the sight of what was towering above him...it was Gary! But a bunch of times bigger than Marshall. His monstrous build contrasted heavily with Gary's sweet, gentle smile looking down at his bf.

7-11. Since Gary already indulged himself with size and candy, he wanted to share his newfound power with his beefy boyfriend to balance things out. He charged a beam of pure sweet candy goodness, and shot it straight into Marshall's mouth!

The young guitarist was really surprised at the fact that Gary just shot a beam towards him! But his surprise became pure bliss once he tasted the contents of the beam. It was a constant stream of creamy, sweet joy coing straight into his body...making his body constantly expand each second he kept on swallowing the beam of candy...

12 (Ending 1). As Gary noticed that Marshall became just as big as him...He decided it wasn't enough! As he sat right behind his colossal bf, he decided to indulge him even further, and spawn more sweet treats to feed them directly into Marshall's hungry mouth, the vampire boy was more than happy to indulge to the situation~

13-20. As Marshall kept on eating and expanding, it was still not enough...he wanted something more from Gary~ As he stood up, he easily picked up almost as gigantic Gary. Having no shame,Marshall gave Gary's ass a loud smack! Enjoying how big his lovely bf was all around. Marshall then proceededto laid Gary on the street where they could have more space, leaving cracks on the ground. Gary didn't expect this turn of events, but they've had experience before hand...but it doesnt make it less intimidating with the fact that his boyfriend that was taking the lead was just as big, if not bigger than a whole building!

Marshall stood on his knees, making the whole neighbourhood shaking each time he landed a knee on the streed, destroying it even further. Gary was already acting up at the sight of his towering bf, his shaft pulsing bigger as he looked embarrassed at the situation...
*SCHLORP* Marshall went straight towards what he wanted, as he put Gary's manhood into his mouth, his mouth stretching with how big the shaft was. Marshall teasingly looked up at Gary, Gary knowing quite well how things were gonna go...

Marshall kept on pleasing his bf with his mouth, stimulating his member, Marshall feeling how it was expanding bigger inside his mouth...*BOOM* The first stream shot right into Marshall's throat, Marshall greedily swallowing it all with no hesitation...*BWOOOMPH* His body violently expanded bigger with the intake of sweet protein, his body starting to get too close to either buildings on his sides.

Meanwhile, Gary was in too much ecstasy to think straight...too much to notice that he was shrinking each time Marshall swallowed his "Gary Sweet Syrup".

Marshall kept on playing with his bf's member, stimulating it more and more, making sure to get more sweet treats from his bf...Expanding more and more, the street getting destroyed under the excessively huge and heavy young giant....His body already damaging the buildings on his sides...

As Gary let out his last stream, he fainted from all the stimulation, as Marshall gently kept on drinking the last drop that was left from their bonding...

21. Gary woke up, not remembering what happened the past hours, including his Halloween adventure with Marshall...and seemingly have lsot his candy powers. With a strong headache, it ook him a while to gather himself. Once he did, he looked around at his surroundings...only to find out taht he was naked in the middle of the street!

He covered himself, and looked around once more, trying to look for Marshall for help...only to find out that his boyfriend was towering over him all along...

22 (Ending 2). Marshall, having kept his current vampire powers, the power to grow from candy, plus the power that he absorbed from Gary, towered over the whole neighbourhood, carelessly flaunting his body above all the people of the city. His voluptuous muscles glistened under the moonlight, his pecs bounced back and forth as he kept on heavily breathing from all the action...and his gigantic shaft showed how excited he was...and how he still wanted more.

He focused his crimson eyes towards his teeny tiny boyfriend...thinking all the unthinkable things they could do together to keep on having fun...Meanwhile, Gary was too scared to even try to run away...while he knew quite well that Marshall would be able to catch him wherever he tried to run away...So the only option was to keep on indulging his now overly gigantic, vampire boyfriend...Hopefully sweet treats from his shop will suffice!...right?
