Chapter six: baby making without a baby

It took Fionna a while to fully register what was going on. She was pinned against Marshall's wall, his hands all over her and her shirt flung over his shoulder. Let's not forget to mention the fact that he was sucking on her lips and it felt amazingly good. But Fionna was still mentally flipping out over the fact that he figured her out so quickly. She honestly thought she was doing pretty good. Apparently she wasn't. The adventuress sighed against his bottom lip as Marshall grabbed her chest, his greedy hands forcing an airy moan from Fionna's lips.
"Mmm…feels good right?" He hummed as she struggled with her breath. She nodded as he squeezed again.
"Really good," she murmured.
"Doesn't take much to excite you, does it?" He continued, reaching behind to undo her bra. She gasped at the audible snap while he worked his fingers underneath. "Or is it just me?"
Fionna whined at his chuckle tickling her ear, involuntarily pushing her chest further in his hands. She gripped his arms tight, her finger tips brushing his flannel. Marshall resumed kissing her neck again, and enjoyed her gasps for air as he did so. He had been waiting so long to hear those adorable gasps and to feel her soft chest. It was better than he could ever imagine (and he was definitely good at imagining). He sucked and licked at her neck, eager to memorize the texture and taste of her angelic skin. Her angelic skin he was currently tainting with his demonic tongue. How pure can an angle really be once a demon gives them an offer they can't refuse?
"Marshall…" she reached up to tangle her hand in his hair, trying to guide him to her lips while struggling to hold back her sounds.
He obliged and followed the path to her lips, desperately latching on to them at once and wasting no time getting his tongue to play with hers. Fionna would be telling a lie as big as the sun if she said she didn't enjoy it. She did enjoy it. Thoroughly. Marshall liked it too, but he mostly making sure he wasn't dreaming everything that was going on. He pulled her naked waist from his cool wall and held her body against his. He kept one hand on her chest and his mouth on hers. She moaned in response, clinging on to him and undoing a few of his buttons on his flannel before quitting and pulling it off all together. She couldn't help but look at his bare chest and spread her fingers over his pale skin. His chest looked the same as the rest of his body; supple, thin, and wildly attractive. He chuckled, distracting her momentarily before she leaned forward and nuzzled in to his neck. Her mouth was warm against his bite marks and he instantly stiffened.
"Ah…Fionna-" he was cut off by a groan as she softly bit the punctures, his hands curling in to fists against her body. "F-Fi…I-I'd advise you n-not to do th…th-Ah!-t," he stammered as she continued with his marks.
"But you make such interesting noises," she whispered. He struggled with a moan as she caressed his neck and dragged her tongue over the scars. "I want to hear more."
"Fionna…I-I'm…sensitive there," he told her, his breath heavy.
"I figured," she said and then sucked on his neck.
He groaned and buried his face in to her neck, reaching up to grab her bunny hat and pull it off. Once her long hair was freed he laced his fingers in with her golden locks, scrunching up handfuls to her scalp and panting in her ear. She giggled and dragged her tongue from his clavicle to his ear, grazing the marks and sucking on his lobe. Marshall growled and shoved her back by her shoulders. Fionna gasped once her spine hit the cold wall again and she looked up at the starving vampire currently pinning her against it.
"You're a bad little girl," he smirked tracing a finger over her jaw line. She was speechless. He leaned forward and kissed her lips once before smiling. "Pop quiz, Fi," he announced.
"Q-quiz?" She stuttered.
"It's mandatory to test you on the content I taught you yesterday. I must make sure you really learned everything," he spoke as his hand drifted down her figure.
"You mean…?" She didn't have to finish her sentence, she knew exactly what he meant. His smile widened in to a grin as his hand snaked under her skirt, ridding it up her hips and giving him space to move.
"Question number one: what is…this?" He asked as he softly pressed against her lips through her panties. She gasped.
"M-Marshall!" He tsked and shook his head.
"Wrong answer. That is not called a 'Marshall', but good guess. Try again," he said starting to knead her damp folds.
"I-I can't remember…glob," she panted.
"I'll give you a hint, it starts with an L."
"L…l…l-laybia?" She guessed, her chest heaving against his.
"Correct," he said pulling down her white panties enough to wiggle in to them.
"Question two: what is this?" He asked and stroked her clit. She moaned loudly, rolling her head back against the wall and rolling her hips against his magic fingers. She was right, it felt a hundred times better when he was the one touching her.
"Clit," she murmured and grabbed a fistful of his hair.
"That was fast, have you felt like this before?" He questioned pressing kisses to her neck.
"Yes…" she admitted.
"Mmm…last night? You didn't even know about it before that." Fionna nodded.
"I…like your fingers better," she confessed, turning redder from what she was saying. His kisses got rougher along with his hand, her simple words exciting him.
"Question three: what is this?" He breathed and shoved his finger inside her. Her hands shot up to his shoulders and she hissed. She hadn't explored that part of her body yet.
"T-that's…my vagina," she managed. For some reason that turned Marshall on even more. He delved his finger in deep, enjoying her plush warm walls while he started to kiss over her breast. She squirmed at the foreign feeling he thrusted upon her, her body bending against his with each time he pushed in, and completely arching back when he added another finger.
"F-fuck!" She whined, trying to get used to the stretch while his thumb rolled circles around her clit. Marshall was too busy sucking her right nipple and trying to dig deeper to realize her nails digging in to his shoulders. He was too absorbed by how aroused he was just from the blond moaning and groaning in front of him. Her whine pushed him too far, his body way too deprived to handle it. He subconsciously rubbed his length against her thigh, finding slight relief in his tight jeans, but it still wasn't enough.
"Marshall…give it to me, dammit!" She ordered reaching down to undo his jeans. Fionna tugged them down along with his boxers and felt him against her thigh again. "Marshall," she whined desperately.
He kissed his way back up to her neck and pulled out his hand to shimmy her panties down her legs. Once she was freed, he hooked his arms under her knees and pushed her close against the wall. She wrapped her arms around his neck and nuzzled against him, waiting for what she had anticipated ever since he kissed her. Marshall started to push in, groaning once he made contact with her warm, wet folds.
"Fuck," he cursed, hiding his face in her long blond hair as she squirmed and whimpered.
"Marshall…i-it hurts," she said between sharp intakes of air. He pressed sweet kisses to the side of her face and up to her lips. She closed her eyes as he kissed her softly and relaxed against his body. With that he pushed a little further, causing Fi to pull back and hiss. "F-fuck…" she whimpered, droplet of wetness starting to gather in her long lashes.
"It's okay, don't worry. It'll stop, you just gotta relax," he assured her in shushed tones. He pulled a strand of hair from her face and leaned in to kiss her again. Fionna allowed him to, enjoying his gentle lips and groaning once he pushed again.
"Marshall," she whispered against his lips. She wasn't saying it because it hurt or because it felt good, she was l
saying it for the sake of tasting his name on her tongue.
"Are you okay? Do you want me to slow down?" He asked, real concern peeking through his voice. She shook her head.
"Keep…keep going," she urged and braced herself by clinging to his neck.
"Are you sure? I can stop if you nee-" he choked on his words as she purposely clenched around him, wiggling slightly to get more of him and sucking on his bite marks again.
"Cut the crap and fuck me already," she demanded, her voice hoarse yet confident. Marshall didn't need to be told twice. He pushed in to her again, his length almost all the way in as she moaned against his neck. "More," she ordered. He struggled with a moan himself. Whenever he stopped she's clench until he moved again. One more push and he was inside her. He took a moment to feel how incredible she felt. Her walls were so soft and untouched. He almost felt guilty for being the first. Almost. Fionna rolled her hips and moaned from what she felt inside her. She loved it. Yeah it still stung a little, but it felt so good the stinging was like a minor cut.
"Y-you have to move," she mumbled and kissed his neck sweetly like he had done before. He was too busy being caught up in the way she was moving. Her hips felt so good, he forgot he was supposed to be the one moving. Once he snapped out of his trance he quickly started to pull out and push back in. Fionna shouted, and dug her nails in his scalp and shoulder. "M-Marshall!"
He smirked, her thighs trembled and squeezed around his waist as he moved his hands down to her ass. She begged for more and he obliged, setting a steady pace and kissing against her jaw. Her body tried to move against his, but the wall left her nearly immobile. All she could do was let him do all the work, yet she so desperately wanted to buck her hips against his. She mewled and whined for him to go faster when she suddenly turned her head away and sneezed.
"Fuck!" Marshall groaned and let his head fall against her shoulder, panting while he stopped momentarily.
"Marshall, keep going," she pleaded, rocking her hips the best she could with her back pinned against the wall.
"That felt really good," he said in a husky voice.
"W-what?" She stuttered.
"When you sneezed…glob that felt so fucking good," he mumbled and kissed her neck. He resumed a slow pace, much too slow for Fionna's taste.
"I-I don't know why…"
"When you sneeze your vagina clenches automatically," he informed her.
"Oh…is that good?" She asked.
"Really good," he said before ramming in to her hard. She screamed as he roughly slammed in to her. He wanted to repay her and make her feel just as good. Fionna's toes curled in her shoes and they started to slip off her heels. She gasped for breath between her wild moans and rolled her head back. Marshall took advantage of her exposed neck and nipped at her skin, squeezing her tush tighter and thrusting deeper.
"Mmm…I'mmmm…Ah! It feels…I can't…" Fionna's voice shivered as she tried to explain. She couldn't describe it, but she was getting so close to that feeling she got last night.
"What's…wrong?" He asked kissing to her ear.
"It feels…so good…I don't know h-how to de…scribe it," she managed.
"Are you gonna cum?" He asked and sucked her lobe.
"I t-think. You d-didn't tell me a-about that," she then whimpered and dropped her head. He grunted at her breathless voice. She sounded so shameless and innocent, and it probably shouldn't have turned him on so much. But it did, and he pushed even harder.
"Me…too," he huffed. She moaned and wiggled her hips as much as she could, getting everything she could out of his body.
"More…more…more! More!" She demanded, moaning each word and pulling on his hair. He chuckled.
"Wow…for your first time…you're quite the sexual deviant," he teased and licked her clavicle.
She ignored him and pulled his lips up to hers, smashing them against her and eagerly prodding her tongue in his mouth. Anything to shut him up. With one last hard thrust Marshall groaned, unable to hold on anymore and cumming inside her. Fionna screamed and tore her lips from his, leaning back as the pressure snapped inside her and experienced her second orgasm. She relaxed against the wall, her legs loosely wrapped around Marshall's waist and her chest heaving. Marshall had to find the strength to keep her in place and himself on his feet, but his knees were so weak he thought he would collapse the second he pulled out.
"How…was that?" He said between breathes. She looked at him and smiled slightly before leaning forward and kissing him briefly.
"Meh."
