This story has been pretty sweet thus far I think it is time to add some lemons. Enjoy…

Chapter 10: Double Date: Part 4: Sit Back and Enjoy the Show

The lights in the studio cut back on as LSP sits comfortably on the couch, "We are back folks, like I mentioned before, the show is now rated M from this moment forward. Oh I hope that the limo camera is still working," He crosses his fingers before the lights cut off and the monitor cuts on.

Marshall and Fionna wobble back into the limo faces crashed into one another, lips locking, trying to find the closest place to sit. They fell back as their kissing intensified; their hands explored every inch of each other's body. FP finally walked in and flung the bag to the side, "Awww you guys started without me." Marshall grudgingly pulled away from Fionna's grasp, "Go ahead FP, have some fun. I think I will have a drink and enjoy the show." He walked over to the mini bar, grabbed a beer and made his way over to the nearest seat.

"Oh so you like to watch?" Fionna said slowly removing her shirt.

Marshall simply smirked while taking a sip of his beer.

"Come on FP, let's give him a show,"

"With pleasure," he said right before Fionna threw her shirt at Marshall.

She moved her hands through his hair drawing him closer, her bare chest pressing against his muscular one. "Remember this?" She said before grabbing a fist full of his hair and pulling him in for a kiss. FP moved his hands to her breasts and started to softy grope them, teasing her nipples with his touch. She pulled her head back in ecstasy giving a sexy smirk to Marshall before turning back to FP. Marshall simply smiled, "You're gonna regret that."

FP laid her across the nearest seat and moved his tongue from her belly button up to her nipples. He sucked softly as she squirmed and twitched under his touch. He stood up and slowly worked her pants down.

"Not wearing any undies, Nice," Marshall said taking another sip of his beer.

FP took in the sight before him and smiled right before pulling his own pants down revealing his throbbing member. Fionna sat forward and pulled his head to her chest massaging his scalp as he moved closer and closer to his goal. He purred at the sensation of her hands tangling in his amber locks. He continued kissing trails up and down her smooth milky skin, running his fingers in her long golden tresses and doing all in his power to make this moment last as long as possible. Tension started to build up in Fionna's back as she anticipated what was coming next. Laying one more kiss to her lips he positioned the head right over the opening, sliding it up and down teasing her folds and tickling her sweet spot. It was driving her wild.

Marshall placed his beer down and walked over to the Fionna. He looked her in her eyes with a carnal smile, "How do you feel bunny?"

Fionna just looked up to him, "What!?"

"Tell me how you feel, I want to hear it."

She smiled; even in the awkward situation she was in, she saw it as a way to get under the vampire's skin. "I feel amazing. FP is blowing my freakin' mind," She said maintaining her cocky smile.

FP had to slightly smirk, happy knowing he was doing a good job.

Marshall reached down placing his finger on her lips and trailed down to her chest, "I see you want to play hard ball, but that's fine. I love the challenge."

He moved down and delivered a soft kiss to her lips. When he was satisfied with himself he left Fionna and returned to his seat.

Fionna's eyes fluttered open, slightly disappointed. She looked over to Marshall with a "Why did you stop expression."

Marshall raised an eyebrow with a playful smirk just as FP slammed into her.

Fionna let out a yelp of surprised pleasure. Laying in closer to her, FP kissed along her jawline wanting to be closer, not wanting to miss one of her sweet melodious moans. She huffed and puffed and gasped for air clawing at his back as he moved his hand down to tease her sweet spot. Fionna felt like jelly under his touch his kisses were so soft, his touch was so precise everything he did was perfect, like he was only thinking of her pleasure.

The two continued on as Marshall slowly sipped his beer and let his mind wonder, "I feel quite crazy for thinking this, but this is not so bad. Am I a pervert? Oh course I am but that is beside the point. Hmmm, it is weird that this is really turning me on. Huh…I wonder if I am a swinger?" he chuckled to himself.

Her back arched as the pressure of the night, the pressure of his thrusting and the pressure of her overall wanting finally mounted up against her and she released.

Her body convulsed as she rode out her orgasm. Flame Prince continued on as long as he could before he released and collapsed to his knees. He laid his head on Fionna's stomach both breathing heavily, perfectly in tune with each other. FP reached up and mindlessly twirled his fingers in her hair content with this moment, happily resting on the one who could possibly be his soul mate…

Their semi-unconscious slumber was interrupted by a loud, slow clap coming from Marshall's direction. They both looked up to see him there with his legs crossed, eyes closed and his head pointed to the sky. "Guys I have to say that was really cute. I am sorry to break up this little moment however I think it is time to show Fionna a little excitement. She's an adventurer after all."

Fionna was not sure but she instantly tensed up, it's not like she had not been with Marshall before but something was different he had a look of hunger and longing and his usual adorable fangs protruded from under his top lip. "He wouldn't bite me would he? No, Marshall wouldn't hurt me… would he?" Fionna only got to think for a few seconds before Marshall and his lightning speed swept her right from under FP's head. When Flame Prince's head hit the seat he just got up, laid on his back, and threw Fionna's shirt over his eyes. "Hey keep it quiet Marshall, I need a quick nap."

"Quiet…ha you wish. There will be nothing quiet about this," He held the bare Fionna close to his chest with a malevolent grin. He then laid her across the seat placing his finger to his mouth, "Be quiet little bunny."

Marshall tapped on the window that connected him to the driver. As the window eased down the driver gave Marshall an acknowledging glance in the rear view mirror, "Yes sir, how may I assist you Mr. Abadeer?"

"Where are we now?" Still focused on the driver, he moved over to Fionna's womanhood and rammed two fingers in. Fionna jolted but covered her mouth making sure to remain silent.

"We are close to downtown AAA sir." The driver responded totally oblivious to what was going on only a few feet away.

"Sounds good, when we hit downtown do me a favor, tap on the window for me." He moved his thumb to her sweet spot and slowly rubbed in a circular motion. Fionna squirmed and fidgeted, not able to control the sensations pulsing through her. Her last defense from moaning out loud was to bite down on her fingers.

"Yes sir. We should be there in about 15 minutes." The driver said keeping his eyes on the road.

"Excellent, I will be waiting on your signal." The driver slowly rolled the window back up as Marshall's rubbing grew more intense. Fionna rolled from side to side, still biting on her finger. When the window was finally up Marshall lifted Fionna off the seat and placed her in his lap.

As soon as she was securely in his lap she punched him in his shoulder. "What the hey hey Marshall. Are you trying to kill me? Look I bit down so hard that my globbing finger is bleeding." She lifted her hand up and as she said small droplets of blood trailed down to her elbow.

Marshall's eyes grew red as he grabbed her finger sopping up the blood that was rolling down her arm. "Fi, you taste so good, do you know what blood does to me?" He moved from her arm to her neck.

He trailed his tongue along her warm skin giving her goose bumps, "Maaarshall…" Fionna said apprehensively.

"Yes bunny…" he said still working his way around her neck.

"Are you going to bite me? Why are we heading downtown? Did you just say my blood was delicious? And what does blood do to you?"

He smirked against her skin, "Oh sooooooo many questions but I will answer one of them. Yes I will be biting you tonight."

Marshall made his way to her right breast and placed it in his mouth. His tongue slowly wrapped around her nipples teasing her getting her prepared for the main attraction. He grabbed the other breast and maneuvered her nipples around his fingertips. Fionna gasped in pleasure as she moved in to his chest, kissing her way up to his neck. She kissed around his bite marks as she felt his body tremble beneath her.

"Does Marshall Lee the Vampire King have a weak spot," Fionna joked.

"Hey… shut it. That area is a little sensitive it rarely gets touched," he said slightly embarrassed.

"Good to know," she said before slowly licking over the marks.

Marshall quaked at her touch, and then looked her in her eyes, "Okay bunny you wanna play, I can play too." He moved up to her neck and slowly grazed his fangs over her soft skin. "Let me show you why sex with a vampire is fucking amazing." Before Fionna could respond he bit down into her flesh. Fionna screamed not so much because it hurt but because she could not believe he bit her. She opened her mouth to scream at him but before she could a weird feeling flowed through her body.

"What…what is this…this feeling?"

"That is what blood does to me. Do you wanna know what bloodlust really means? After a vampire drinks blood there sex drive increases 100%, allowing us to produce a toxin that can increase our partner's sensitivity exceptionally. In other words your body will be on fire when I am done with you."

Fionna's body tingled all over, never had she felt such a sense of clarity in her life, she felt everything. Marshall's slight breaths on her skin drove her wild, she wanted more. She reached for his pants trying to pull them down and take this feeling to the next level.

"Sorry baby doll, you gotta wait for this but this should hold you over." He reached for the back of her head and pulled her close. Their lips locked as Fionna's mind went wild. She had never felt this way before, the only way to describe it was it felt like she was having a million little organisms all over her body, and it was mesmerizing. Their tongues intertwined, Marshall grabbed her closer as the toxin coursed deeper in her veins. Just as their kissing was drawing to a close the driver tapped on the window.

"Well bunny that's our cue." He said stand to his feet and unbuttoning his pants.

"Cue, for what?" She said rolling back and forth on the seat, because everything that touched her skin felt so good.

"For our performance of course," He opened the sunroof and picked up Fionna. "Sooo it's Friday night, and we are in downtown AAA the most popular place there is. I know the streets are crowded…"

"MARSHALL what are you thinking…" She said cutting him off.

"This." He picked Fionna up and they both stood in the opening of the sun roof.

The wind smashed against their skin, "Marshall, this air on my skin….awwwwww," she was unable to finish her sentence too caught up in this marvelous feeling.

"I hope you guys are ready for a show." Marshall yelled to the hordes of people. He picked Fionna up wrapping her legs around his waist and banging his way into her womanhood. Fionna let out a yelp that echoed through the night's air.

The people on the streets looked in disbelief. People yelled as they rode by.

"Get a room you two..."

"Dude that's hot…"

"Hey there are kids out here…"

"Fucking awesome…"

"I'm never coming back down here again…"

"Nice tits…"

Marshall heard all the comments and he loved it. What better way is there to give a big fat middle finger to the citizens of AAA then to have sex riding in there most crowded location? And why would he do this you ask? Well that's simple, he's flippin' Marshall fucking Lee, that's why. Nothing more, nothing less. This excited him more as his thrusts became more sporadic and accelerated.

FP was awakened by all the yelling from outside the limo. He woke up and got an eye full of Marshall Lee's pale ass. "Having sex outside? Dude, that was an awesome idea, really wish I would have thought of it first, however for my enjoyment please turn around. I would rather see Fionna's ass." He said nonchalantly.

Marshall laughed out loud as he turned around to give FP the view he requested.

"Thanks man, that's much better."

FP sat up and thought to himself, "I would love to see how this looks from the outside." He rolled down the window and hung out to see not only Marshall and Fionna having sex but the surprised looks on the people's faces as they rode by which was priceless. He took out his phone and started snapping shots, "

"Marshall whatever your doing don't stop, this is hilarious." He said snapping picture after picture.

"Oh don't worry, I won't."

Fionna's body was in overdrive. The cool breeze against her naked skin, Marshall's venom, and the rhythmic thrusting was maddening. The crowd's hoots, hollers, cheers, cussing and fussing was such a turn on. She never did anything so wild in her life; her heart pounded faster the further downtown they went. She felt sensations run through parts of her body she did not even realize she had. Marshall sucked around her collar bone moving his way down her nipples sucking and nibbling. Fionna's breaths became erratic, she had lost control of her body and Marshall had no problem picking up the slack. Marshall's eyed the vulnerable damsel before him and felt it was time to end her suffering. He reached down and slowly rubbed her sweet spot as he slowed down moving in and out painfully slow making sure to penetrate every part of her insides. Fionna's head flew back and her hair swayed back and forth dancing in the wind. Her body tensed as her legs grew tighter around his waist.

"Marsh…Marsh…MARSHALL" she screamed as she finally released, melting into Marshall's arms.

After a few more thrusts Marshall finished as well, and it took all his strength to keep him and Fionna standing, he figured it was time to end their little show.

"Well folks it's been fun," he said before ducking back into the limo and closing the sun roof.

He laid Fionna across the seat as he picked up his pants and put them back on. He walked over to gather Fionna's clothes and brought them over to her. She stood up weakly, "Thanks," She said putting them on. FP slid back in and closed the window.

"Well since all the excitement is over I am going to catch a few more zzzz's," He laid back across the seat and closed his eyes. Marshall sat down and Fionna came and nuzzled in his lap.

"That was amazing Marshall, I've never felt like that before. My body is still shaky."

"Yeah baby, I have that effect on people." He said with a sweet grin.

She elbowed Marshall in his ribs, "Shut up, hey, I do not feel the tingle anymore…what happened?"

"Oh it wore off once you…uuhhh… you know, released."

"Well I do not think I can go home now. I am sure my older sister Cake saw that wonderful display and will try to kill me if she sees me."

Fionna felt a vibration in her pocket, she reached in and pulled out her phone. "Huh… I have 15 missed calls and 6 text messages." Fionna started reading off the messages,

"Fionna what are you doing?"

"You are on TV having SEX!"

"Girl I am going to KILL YOU when you get home."

"You better answer me!"

"I am going to KILL those boys when I get my hands on them."

Marshall and Fionna both let out a slightly nervous chuckle. "Well guess who is not going home tonight," Fionna laughed. "Can we hang out at your house for the night? I am not going home to that, plus I am hungry I think I deserve some bacon pancakes."

Marshall chuckled, "Sure bunny, I will be an expert at making those if we keep this up."

Fionna laughed as her face turned red. "Marshall I have had the best night of my life. FP and you were amazing. The amusement park, the karaoke bar the strip club, it was all amazing. I just do not know what I will do. I really like both of you. You both have amazing personalities that blend so well with my free loving one. I just don't know Marshall."

Marshall gently brushed her hair, "Shhh shhhh it's fine Fi. I know when elimination comes up you will make the right decision."

Fionna sat up amazed and looked him in his eyes, "So isn't this the part where you say I should pick you?

Marshall smiled, "Yes in the beginning, but I have grown attached to flame boy. He is a decent guy with a good heart; if I had to lose you to anybody I would not mind it being FP. Don't get me wrong, I do hope you pick me. I feel like you are the missing part of me that I have searched for. Countless years, decades, centuries searching for someone who understood me, someone to spend a little bit of my endless forever with…"

He laid his head on hers and smiled, "but more important than my own happiness, is yours."

He knocked on the window to get the driver's attention. He rolled down the window, and looked at Marshal in the rear view mirror "Yes sir."

"We are done for the night, could you please take us all back to my house?"

"As you wish sir."

The monitor cut off and the lights in the studio cut back on.

LSP is seen standing staring into the monitor. He fell to his knees quickly pumping his fists in the air. "Yes,,,yes..yes. So hot…so globbing hot." He finally got up and took a seat on the love seat. "Guys you will not find this anywhere else, love, passion, drama, excitement, steamy SEX all here with your ole pal LSP." He laid back on the couch kicking his feet back and forth, "But unfortunately for you it's time for a commercial break."

A/N: Awww… Marshall is such a sweet jerk, you don't know whether you wanna hug him or kick him in the boy loins. Thanks again for reading and keep up with my story. Please Review.
