Teaching Finn

"Marceline! For the last time, you need to stop trying things with Finn!" Bubblegum shouted.

"Aww, c'mon Bonnibel, look at the poor kid! I bet he never even came before! He probably doesn't even know what masturbating is!" she protested.

Bubblegum thought for a moment. 'hm, perhaps Finn would benefit from at least knowing how to do that, and what it is like to orgasm' she thought. She nodded for a moment. "Okay Finn, stand up," she ordered. Finn, not knowing what to do, stepped forward, still somewhat hard.

"Bonnibel, had a change of heart have we?" Marceline smirked.

Ignoring her, Bubblegum simply began to instruct Finn. "Okay Finn, now remove your pants"

"What? B-but PB! I don't- can you like... turn around?" he asked.

"No, this is important, Finn" she insisted.

Finn hesitated for a moment, then began to reach for his fly. Not moments before he had undone the front of his pants, Marceline snuck behind him and ripped them off. Finn, now blushing and standing, trying to hide himself, was quite uncomfortable. "Um... So what now princess?" he asked.

"Now Finn, you need to remove your underwear" she instructed.

Finn blushed, obviously too embarrassed to proceed. Marceline, still behind him, again grabbed his clothes, almost pulling off his underwear. He grabbed onto the waistband, struggling no to let them fall.

"Ugh-c'mon kid! Gah! Just... Let... Go!" she struggled, claws now dragging threw his underwear. A loud rip was heard, and in an instant Marceline had shredded his clothing. Finn hadn't even noticed what had happened, until marceline roughly gripped his length. Bubblegum stood, mouth agape, astonished. "what's the matter Bonnibel, I thought you had seen one of these before?" Marceline teased.

"He-he's... I just... Didn't expect Finn... At his age... He's certainly, um... Well 'equipped' for his age," she replied slowly.

Marceline started moving her hand a little, until she reached the tip. "Wait... How is Finn circumcised? I thought that was, like... How?" she asked.

Bubblegum overcame her trance, shaking her head. "I dunno, I guess that's a secret that died with Finn's dog-parents," Bubblegum answered. Despite her surprise, Marceline hadn't stopped moving. "Okay Marceline, that's enough. we still need to teach him about masturbation," Bubblegum insisted. Marceline paid her no notice, instead resting her neck on Finn's shoulder, smiling devilishly at him while he squirmed. She increased her speed, focusing more on his head. He squirmed more, much to her amusement. Bubblegum could see this wouldn't stop anytime soon, so she decided to try her best to continue her lesson. "Um... So Finn, when you masturbate, you would typically do what Marceline is doing, but you would do it to yourself," she informed him. Finn's knees started to go weak, his jaw started trembling, his eyes started fluttering. Bubblegum Could tell, he was clearly close to release. Bubblegum sighed, "Okay Marceline, go ahead," she permitted.

"Hm? I thought you would want to do that Bubblegum..." she teased, obviously aware that Bubblegum was somewhat jealous.

"I-uh... Y-yeah, sure," she stuttered. She walked slowly towards Finn, now calming down a little seeing as Marceline had slowed down, almost to a stop.

"Now kneel down Bonny," Marceline was now instructing. The princess, for once in her life, immediately obeyed Marceline. The vampire released Finn from her spell, allowing Bubblegum to do her own thing. The princess knelt down before Finn, staring up at him, both curious and in deep thought, and took him in her hand. Slowly mimicking Marceline's actions, she once again brought Finn to the point of release. Marceline had a sly plan up her sleeve, she knew she could have some fun here. "No Bonnibel, not like that! Here, do this," she insisted, before quickly pushing the two together, making sure Finn managed to slip into her mouth.

"Marce-mmmph!" the princess protested, before realizing just what had happened. Finn's eyes bulged out, his face in a mix of pure shock and ecstasy. Bubblegum tried to take herself off of Finn, but as soon as he was out, marceline snuck behind Bubblegum, and pushed her back on. Finn was having a hard time trying not to buckle his knees, but he wasn't exactly going to ask them to stop.

Bubblegum squirmed for a while, making sure to be careful with her teeth, but eventually accepted the fate that Marceline had in store for her. Not that she wasn't enjoying herself. She slowly bobbed her head on finn's dick, not even noticing when Marceline snaked her hands away. She twisted and turned her head, even managing to swallow Finn right to the base of his manhood.

"Ah!" Finn shouted and moaned, "what- what is- aaah- happen-" but before he could finish, he spilled forth into bubblegum's mouth, unable to control himself any more. Bubblegum was surprised-he had came quite a lot, but she guessed that's to be expected when it's been building up for this long. She stepped back, or rather, 'kneed' back, and considered what to do with the load she was carrying. Finn, unable to stand now, fell to his knees, staring the mouth-filled Bubblegum in the face. She caught his gaze, and without thinking, swallowed all of what Finn had given her.

"...Wow..." he muttered.

"Ya'see kids?" said Marceline, "It's all in good fun."

Bubblegum was a little angry now, that Marceline had forced her and Finn go much further than they had intended. She stood, hands at her hips. "Marceline! What the hey?!" she shouted, "You know that I dislike sexual... Things! Why would you do that? All we wanted was to make Finn cum!"

"Well you certainly seemed to enjoy yourself," she debated.

"Wha- well- uh- that's besides the point!" she objected.

"Well fine, if you don't wanna continue, I'll be happy to show Finn the ropes," she shrugged.

"What?! That's not what I-!" but she hadn't even finished, and Marceline already had Finn out the window.

"Don't worry Bonny, he'll be in good hands. And so will I, hehehe..."
