Finn blushed madly red as she ran her hands across his chest, grinding herself against him through his pants. Finn moaned softly as she grinded more and ripped his shirt from his chest dragging her nails across his bare chest causing him to moan from both pain and pleasure. He looked up to see her throw her shirt and bra aside as she moaned feeling the cool air against her breasts. He blushed deep as he saw her pale breasts and she smiled seductively. "Go ahead Finn touch them, they're all yours." He gulped and moved his hands up to grasp her soft breasts as she let out a moan. "Mmmmm yeah Finn ravage me.." She moaned as she guided his hands across her breasts. As he massaged her breasts she reached around an started to rub him through his pants licking her lips as he got harder and his bulge got bigger.
She smiled and moved to yank his pants off throwing hers off as well as she straddled him and began to kiss him hard and passionately, her tongue exploring every inch of his mouth. "Mmmmm Finn baby I want you soo bad..." She moaned into his mouth feeling his cock rubbing against her dripping folds. She pulled back with a gasp before sliding down his cock moaning with every inch untill he was all inside her. It felt soo amazing to Finn as he moaned paralyzed from the feeling of her body around his cock. He felt Marceline grip his shoulders as she started to move up and down, his cock sliding in and out with ease as she dripped all over him. As Finn gripped her hips he began to feel something change as her body got hotter and hotter and her moans turned into growls as she moved faster and faster. He looked to see her eyes black and her pupils glowing bright red, her fangs had grown a bit too as they hanged out of her lips. She let out a growl and pressed her lips against his hard as she almost sucked the air from his lungs, her fangs poking his lips a bit causing them to bleed a bit as her tongue licked up every drop that came out.
She pulled back and from his lips and pulled herself back so he was now on top of her. He gripped her legs spreading them as he started to thrust faster and harder into her as she moaned and growled in extacy. "OH GOD FINN YES!" She cried as she wrapped her legs around him reaching her limit. After a hard thrust deep into her he moaned letting his load fill her as she cried out in pleasure from felling his hot seed fill her up. He panted laying on top of her but found her gripping his shoulders and pulling him up for more tongue action as they kissed. "Were nowhere near done Finn" She growled as she flipped him and started to stroke his cock again untill it regained its vigor and size. Finn gulped wondering just how much loving she was going to demand.
After Finn had his vigor back she began to take him for the ride of his life. Finn soon found him pressing her against a wall as she wrapped her legs tightly around his waist and she sucked his neck marking him as hers as he thrusted harder and harder. They moved to just about everywhere in the room even finding to Finns surprise themselves doing it on the ceiling as she used her powers to float up. Orgasm after orgasm they continued for what seemed like hours to Finn untill she was riding on top of him growling in her bliss of pleasure. Her body felt like fire around him as she pounded him into her. He moved his hand up thinking he could give her a little taste of her own medicine as he pinched her nipple hard and pulled it over and over again, causing her to cry out from the pleasure and the pain as she her body finally reached its max. Her back arched as she let out a loud howl of pleasure as he came inside her, her whole body shaking and trembling from pleasure as she collapsed onto him breathless from her sexual marathon. Finn panted heavily and passed out exhausted from what was the longest an hottest sex he had ever had. She laid next to him as her eyes returned to normal and her fangs receded.
She sighed a sigh of relief and saw he was passed out, she giggled and pulled the covers over them and laid her head on his chest using her claws to etch in a M on his chest. The next morning came and Finn groaned feeling the sun beat at his eyes. "Uggg..." He looked to see Marceline gone an a note with some colorless strawberries by the bed. "Dear Finn, sorry about last night, We get like that when were going to mate but I'm sure you didn't mind. Anyway I went to the night-o-sphere for my gig and I didn't want to wake you so just try to relax today I'll be home tonight, Love Marcy" He blushed setting the letter down picking up the strawberries before munching on them. He couldn't help but think how great they seemed to taste without the red for some reason. After finishing the bowl he got up ad stretched before going to shower. He came out with a grin at how refreshed he felt and decided to go get some air.
He stepped out seeing the cave she lived in and walked out to see the sun and a large grassland before him. He sat down as the cool spring breeze blew across his face, he could barely make out the candy kingdom in the distance and was amazed how far he was taken from his little home in the woods. He sighed figuring he should stay put less he tempt Marceline wrath and headed back into the cave. He saw the house and realized it was a total mess. He went inside and du around before finding some dusty cleaning supplies and decided to spend the day cleaning for her. It was much more a job than he thought as he sifted through bottles of booze and trash all around. "Geez what a pig.." He thought to himself as he picked up her underwear and bras that were lying around as he blushed deeply. He spent most the afternoon scrubbing hard at almost every inch of her house before finially getting to her room. It didn't take him long to sort and clean and as he picked up the last bit of clothing something fell out...it was Marcelines diary...
