What happened last:

Marceline is still day-dreaming. Around the time that Princess Bubblegum was sitting at her computer, trying to hack the mainframe of the Guild of Assassins, Finn and Marceline had a lot to talk about and catch up on along with some other things...

F: "Well… I would hate to be rude…"

That's all Finn needed to say to get Marceline going. She was going crazy already and they hardly just started. She knew what Finn was (hopefully) planning on doing and she was going to do whatever she had to in order for that to happen.

For about the next ten minutes they went back and forth. He would bite her lip and she would press her body up against him. He would pull her hair and she would claw at his back. It went on and on; hearts beating faster and faster.

Finn stopped for a second and lit a candle that was sitting on the table nearby. It was as if he was planning this…

The atmosphere began to electrify as things started heating up. They were exchanging body heat as they got closer and closer. Marceline was colder than usual so Finn had to keep up with the intensity in order to stay warm. And that's exactly what he did. He kissed the vampire queen as passionately as ever, doing whatever made her go crazy.

He began to slide his hand down her stomach towards her waist ever so slowly. He wanted to tease her a bit before doing anything. But even he didn't want to wait. He started to unbutton her pants and was halfway to taking them off until…

BMO: "Hey Finn! Are you awake yet?!" Beemo said, not trying to sound quiet at all.

Beemo must have snuck in at some point. It couldn't have been that hard because Beemo is soo small and Finn and Marcy were too into what they were doing to notice anything.

Marceline instantly went invisible and Finn pretended to be asleep. It was the perfect disguise.

A few seconds passed and the room was soo quiet that a pin could have been heard dropping.

BMO: "Oh ok. I will come back later." Beemo said, at least this time he attempted to whisper.

After a few seconds of silence, Marceline became visible again and they both started laughing.

F: "Why didn't we think of that before?"

M: "I dunno. But we should defs do that next time." She said as she raised an eyebrow. She emphasized the last two words in her sentence to indicate that this was going to happen again. As if it wasn't already obvious to Finn...

F: "Heck yes. That's way better than-"

Marceline stopped him in mid-sentence as she likes to do by kissing him. She was trying to get him all riled up so he would do what he was about to do.

It didn't take long. After about five minutes, Finn was reaching back down to Marceline's waist.

Right before Finn continued to take Marcy's pants off, she stopped him.

M: "Hey…"

F: "What Marcy?"

M: "Go lock the door."

F: "That's actually… a really good idea."

Finn got up to lock the door and was quickly greeted by a barely clothed vampire queen when he turned back towards the bed. She was good at taking her clothes off really quickly. All Finn could see is that she had a shirt on, it covered up everything so he couldn't really tell.

M: "Hey Finny…" She said in a sexy voice as she grabbed him by the wrist and walked him back towards the bed.

F: "I already know what you're thinking so I'm not even gonna play dumb for you." He playfully said as he started to aggressively kiss her.

She was loving every moment of this. She always liked when he was assertive and when he acted like this.

Marceline kept slowly leading Finn towards the bed until she was right next to it then she stopped. That's when Finn put his hands around her waist and pulled her in closer to his body so they could create that same perfect exchange of body heat once again. Finn was beginning to grasp the general concept of all of this "kissing"" stuff pretty well. Now he just needs to figure out some other things…

Marcy sat down on the bed and tugged on Finn's hand to make him sit down as well. She took his hand and put it on her thigh; she would leave the rest for him to figure out.

She then grabbed his face and continued kissing him. It was very obvious at this point that she really wanted something. The further up Finn's hand went, the more intensely Marceline would kiss him. She was losing her mind and she loved it.

After a few minutes of Finn not doing much besides teasing, Marcy spoke up.

M: "C'mon Finn. You're killin' me here…" She sounded out of breath.

F: "I'm pretty sure it's called teasing-"

As soon as Finn finished that last word, Marceline jumped on top of him and kissed him like she was never going to see him again. She was at least glad that Finn knew what she wanted but she was getting restless because he was teasing soo much.

M: "Finn, am I gonna have to-"

She was interrupted by a euphoric shock sent throughout her body. It took a lot of self-control on her part to refrain from getting too loud. Her face lit up with a big smile as the pleasure began surging in her veins.

F: "What was that, Marcy?" Finn said with a sly tone and a smirk on his face.

His hand was already down Marceline's pants at this point. She didn't expect him to be this assertive.

Finn, although still mostly inexperienced with this, was learning quickly. It didn't take a rocket scientist to figure out what Marceline liked and what she didn't.

He was ever so lightly touching Marceline on one of her most sensitive areas and she still seemed to enjoy it immensely. As the intimate moment progressed, Finn would touch her with more passion and aggression and she would respond with more moaning or pulling on his shirt.

A minute or so passed with Finn "figuring out" the vampire queen. She was gradually sounding more and more exhausted and moaning louder.

M: "Oh, Finn…" She said. Her voice was sounding higher pitched than normal.

As Finn "learned the in's and out's" of Marceline's body, he kept speeding up. He was trying new things and Marcy was loving every second of it. She started to move her hips with the same rhythm of the hero boy's hand.

Occasionally, he would bite Marceline's lower lip to make sure that she had the same powerful feeling the entire time.

This wasn't a hard feat to accomplish because it's been many years since Marceline has had any intimate moments like this with anyone. She was going crazy the whole time and couldn't seem to get enough.

Eventually, Finn found that one unique spot on Marceline and her whole body began to shudder as she squeezed Finn tightly.

M: "Uh!" She moaned louder than normal.

Finn had a huge smile on his face at this point; knowing that he was able to make the vampire queen feel this way.

She kept getting louder and she started to claw at Finn's back harder and harder. It almost seemed as though she was in pain but she most certainly was not...

F: "Are you ok Marceli-?"

M: "-Yes, just keep going." She said with an almost demanding tone. She didn't mean to be rude, her mind just wasn't working quite right.

Finn obviously didn't mind, he wanted to make Marcy lose her mind. And that's what he was going to do. He kept going faster and faster; slowly going harder and harder.

The vampire queen could hardly contain herself any longer. She was getting closer and closer to her peak and was getting louder as the pleasure increased.

M: "Finn…"

She was moaning his name at this point, and he loved hearing her say it.

Suddenly Marceline's entire body began to shudder again and she clawed at Finn's back harder than ever before. She was tearing at his shirt but Finn didn't mind, at least not while he was occupied with the beautiful vampire queen.

He looked at her face as she was getting closer to her climax. She looked as though she was lost in the overwhelming pleasure that she was feeling. Her eyes were closed and she was biting her lower lip. Everything she did was mesmerizing.

Then as she reached her peak, she buried her face in Finn's shoulder so as to muffle her sounds and she began moaning uncontrollably louder. She moaned in a higher pitched voice than normal. It almost sounded like whimpering but Finn knew that it's just because he was doing it right.

Mathematical

After Marceline calmed down, the two just rolled onto their backs and just laid there for a minute or two.

M: "Well, that was… good…" She was still trying to catch her breath. She was under exaggerating immensely...

F: "I'd say so. You were almost screaming for a second there." Finn said playfully.

M: "Oh shut up." She said as she playfully hit Finn on the shoulder.

Finn didn't have much to say after that. He was just taking in everything. He felt like a king that just conquered an empire.

Finn playfully hit Marceline on the shoulder just like she did. She didn't say anything; she just hit him again, but a bit harder this time.

Finn rebutted with another playful, yet harder hit and Marceline replied with a slap to the back of Finn's head.

They sat in silence for a second, both calculating each other's move in this situation. They both knew what the other was thinking; it was just a matter of who would get the element of surprise. Suddenly, Finn jumped on top of Marceline and put her in a headlock.

F: "Ha! I got you now!" He yelled playfully.

M: "I don't know what you're… talking about!" She said as she struggled to pull Finn's arm from around her neck.

Wrestling was one of their favorite things to do together. They didn't always do it but when they did, it was usually spontaneous and completely uncalled for.

They were both struggling for the dominant position and in doing so, fell off the bed and hit the floor with a thud. Neither of them cared if anyone could hear, they were fighting after all.

Marceline would usually be able to win quickly but she had little to no energy because of what her and Finn just got done doing. She thought of ways to win and couldn't think of any that wouldn't require her to cheat.

Finn was about to win with his signature rear naked choke but Marceline suddenly turned into a bat and flew into the ceiling.

F: "Aw c'mon! That's cheating!"

M: "Well… I'm not as strong as I usually am. So it's kinda fair right?" She was hinting at the intimate moment that just happened only minutes ago.

F: "Uh! No! It's still not fair!" Finn wasn't honestly upset; he was just playfully arguing with Marceline.

M: "Oh, boo hoo." She said as she turned into a large demon and picked Finn up by his backpack.

He was just dangling there, swinging his arms and attempting to find some way to break free of her grasp… to no avail.

F: "Ok, now this really is cheating." He said, crossing his arms.

Marceline just transformed back to her regular human size and kissed Finn on the forehead.

M: "I know."

The two ended up joking around and talking about random things for a few more hours until Jake went to get them.

Back to the Current Time

As Marceline's daydream reached the current time she became aware of her surroundings once again.

It was time to save Finn.
