Oh, Marceline!

“Someone’s hungry,” teased Marceline as she noticed Bubblegum’s face dive.

Princess Bubblegum made an annoyed growling sound, sat back up, and brushed herself off as if she had fallen on the ground.

“Awww.  That’s it?” groaned Marceline.

“I slipped.  Nothing more.”

“Well I think Finn’s little hero has a different take on the situation.”

Finn’s penis was standing straight up, and a single of drop of precum oozed from the tip and down the shaft.

“Wow!  What’d you do, PB?”

“Nothing!  I just slipped and got right back up.”

Marceline sighed and stared at her friend with disappointment.

“You just don’t make sense… There’s no denying that you like Finn, and I’ve seen you drool over his dick.  Just give the poor little guy a blowjob and be done with it.  You’re drawing this out way too much, babe.”

“But…”

“But what?!”

“But oral sex serves no biological purpose.”

“First it was germs and now it’s biology,” sighed Marceline.  “At least pick just one.”

“They’re both good reasons to be opposed to oral sex.”

“Listen.  You need to get passed that stuff.  And you just made out with a vampire for crying out loud!  How does kissing serve a biological purpose?”

“It doesn’t but…”

“But what?!” Marceline said with annoyance.

“But…it’s something that’s culturally accepted and normal.  People kiss all the time.  It’s not a big deal.  You know, it’s just…cultural and stuff…”

“I can’t even stay mad at you, PB.  You’re just too funny.”

“Don’t be doubtin’ my stuff!  I’m serious.”

“That’s the funny part.  But we both know that you still want Finn’s juicy meat rod.  You already know it like the back of your hand from your obsessive examinations, and from what I remember, you loved every inch of it.”

“I just wanted to take a look at it as a scientist, and as a scientist I was very…impressed…with his male reproductive organs.  His penis looks very healthy, and his testicles show no signs of damage from the kicks in the groin that I’m sure he’s gotten.”

“It’s time for a song,” said Marceline.

“…what?”

“I’m going to sing a song about cocks, and you’re going to listen.”

Princess Bubblegum crossed her arms and pouted.

“It’s been a while since I played naked in front of someone,” said Marceline as she pulled out her guitar.  “Now get comfortable.  This is gonna be a looooong one,” she said with a wink.

Penis, be good to me.

But don’t give me no baby.

I just want your love.

I just want your love.

Penis, I know you’re shy,

But lemme wrap you up real tight.

I just wanna feel you throbbin’.

I just wanna feel you throbbin’.

Penis, my world is yours to rock.

Nothin’ better than a big bad cock.

Fill me up with your with love,

Your hot sticky love.

I just want your love.

I just want your love.

Let me touch your private place.

I wanna see that look on your face.

You’re my boy.

You’re my man.

I wanna feel that cock in my hand.

Penis, squeeze anywhere you like.

My body is all yours tonight.

If you wanna shut me up,

You know where it goes.

Or say the word,

And I’ll strike a pose.

Make me feel your lovin’.

I need to feel you throbbin’.

Penis, why you gotta be so coy?

Don’t ya know you’re my toy?

My sweet baby boy.

I just wanna feel you throbbin’.

Throbbin’ til you…

Penis! It’s a bumpy road!

Cover me with your load!

I’m gonna…

I’m gonna…

Penis!

When Marceline finished her song she was sweating and out of breath, and she may have exaggerated it a bit to tease Bubblegum.

“So what’d you think?” she asked.

“Meh.  It was okay I guess,” said the princess with a shrug.

“Doesn’t it make you want to get all touchy feely with Finn’s junk instead of just poking at it with a protractor?”

“Not really.”

“You’re so weird, PB.  Girls love cock.  That’s just the way it is, and you’re in denial.  That’s all there is to it.  You can’t even keep your excuses straight.  We love hot bods and cocks.  And since Finn is lacking a little in the hot bod department, it’s only natural to go for his cock,” Marceline said as she pointed at the sturdy erection.

“What’s wrong with his bod?” asked Princess Bubblegum as she suddenly yanked Finn from his sleepy spot and cradled him in her arms.

“Nothing,” answered Marceline holding back a chuckle at the sight of the princess’s motherly behavior towards Finn.  “I love it.  It’s just…not the best I’ve seen, ya know?”

“Don’t be so shallow, Marceline,” shouted the princess as she held Finn closer.  “He’s a beautiful young man with plenty of time to become the hunkiest hunk in all of Ooo!” 

As she said this, Princess Bubblegum took Finn’s penis in her fist and began pumping furiously as she scolded Marceline.  Marceline’s eyes slowly looked down at the shocking display, but the princess kept her fiery eyes focused on Marceline the whole time as if she were pretending not to notice what her own hand was doing.

“And another thing,” she continued, still with her hand rapidly stroking Finn’s erection.  “I don’t have to prove anything to you, honey!  I can be as wild as you, and you know it.  So stop pressuring me to touch Finn!  I can do it whenever I want!”

The hot tempered princess went on like this for at least a minute, and her groping hand didn’t skip a beat.  Marceline stared in shock and tried not to say or do anything to snap Princess Bubblegum out of the moment.  Her eyes just darted back and forth between her blabbering mouth and her fap-happy fist.

“Finn is special, Marceline!  I think you’re just jealous that you’ve never learned to appreciate him like I have—”

And with that, Finn came.  It wasn’t the explosion that both girls had secretly hoped for, but the princess was still in awe of it.  None of it shot out and hit her face, chest, or anything.  It just shot up and back down into her hand, and it oozed between her fingers.  But it was special.  It wasn’t the result of an experiment.  It was like a little sticky present just for her.

“It’s so warm…”

She looked over to Finn to see if he had woken up, but as she expected, the sleep potion’s effect was still going strong.  She gave him a kiss on the cheek and glanced over at Marceline.  The vampire was drooling and had her hand between her legs.
