Finn The Human x Reader lemon (Adventure Time)

03 | Home Alone

*so here's the lemon. If you don't like lemons GET OUT :) thanks :) *

It's been a year since you moved in with Finn and Jake in their tree house. Jake has been busy with his newly born babies that were OH SO CUTE. And Finn and you have been really close.

Your pov~

The front door slammed open and I could hear Finn banging around the kitchen while I took a hot bath. What's his problem?

"Finn?"

" ( y/n )? Sorry I didn't realize that you were home. He walked up the ladder and entered the washroom to brush his teeth for bed.

I immediately rush to cover my body. Finn sees me and we both blushed red. Him and I had never seen each other in this way before.

"Hey. Why cover up? You're beautiful."

My checks flushed up as he gingerly approached the bath tub.

"Umm weren't you cooking something?"

"Nah, I'm not hungry." His eyes scanned my body underwater.

"Is Jake here?"

"Nope"

" Finn BMO's calling for you."

"I don't hear anything..."

"Look outside!" I shouted. "It's the Ice King!"

But Finn wasn't fooled by my games. "Dang man, if you want me to leave so badly say it!"

"No no, I just imagined that this would go differently."

Finn looked puzzled. "What do you mean differ- wait. You thought about me seeing you naked before?"

"Well yeah. I'm a sexually frustrated teenager."

He chuckled "why don't I get you out of this tub then?"

I don't argue. Butterflies are going crazy in my stomach as he picks me up bridal style naked and wet. We lie on his bed while I drip on to him.

Finn kisses me softly around my neck, teases my ear, and slides his hands on my bare skin. I let out a moan. After a minute of feeling he moves to my mouth passionately making-out as he climbed over top my body.

"I'm really nervous. Are we doing what I think we're doing?"

Finn sat up "Only if you want to of course."

I thought for a moment. Mainly just to bother him, though. There was no one else I wanted to lose my virginity to.

"Yeah. Just go slow." I studied his face for a reaction but his eyes seemed to be locked on my body.

"Okay." Finn then looked around him. "We have no protection?"

"Just be careful. I trust you..." While tracing his abs under his sticking-soaking blue shirt, my lips kiss him fiercely as the moment becomes more heated.

He began to peel off his clothes with my help, and we toss them beside the bed. I run my hands through his hair and sloppily kiss him. Finn was definitely excited and aroused now.

I crawl backwards, gliding my hands along his body stopping at his heat. "I can take care of this" my breath hot on him.

To Finn's surprise I give a long, slobbery lick all the way up his shaft while studying his features for a reaction. He moans and grabs the blankets.

After a bit of oral he was very close to his release, but I stopped as his moans intensed and earned a scowl instead. We switched positions so I was laying on my back with my legs wide open.

"Looks whose wet..." Finn hungrily lapped between my legs. His tongue worked magic as I moaned in pleasure, holding his head against my body.

"Arrh don't stop!" I yell. Using his fingers he played with my heat as if he was using BMO's controller. I could feel my high rising, the pressure building in my hips. But like I did to him, he stopped.

"Are you sure you've never done this before?" I panted.

Finn laughs. "Positive."

We flopped down on the bed still high on pleasure. Taking a minute to slow our breathing. But we weren't done yet, or I certainly wasn't.

Finn propped himself up on his elbows and eyed my body. "Are you ready for tier 15?" he smirked.

"Whaa-?" I began to question what he had said but he cut me off, cradling my body beneath his. His strong hands were gripping my hips.

"Open your legs." he demanded.

I sheepishly obeyed.

Very quickly he filled me up. It hurt so bad. Really, really bad that I felt myself tear up and covered my face in embarrassment.

"I told you to go slow!" I hissed.

He leaned into my ear. "I'm sorry ( y/n ) but ugh this feels mathematical!" While deep inside gave my shoulder a love bite, distracting me of the pain. I let out a small moan.

That's when I ignored the pain altogether and started to grind against his hips. We moved together in motion, first slow and hesitantly, then wildly and passionately. The pleasure started building up again, and I could tell Finn was close too. I let out a moan. An intense orgasm ripped through me. It left my body shuddering as I struggled to gain control. "Oh Finn.."

Next was his turn. He let out a moan, gripped onto my body and implanted his seed. A quiver soared through his body as he collapsed beside me, panting and sweaty.

Shit. He didn't pull out.

"Finn what the fuck! Are you ready to be a father at 16?" I cried out. " What is Bubblegum going to say? Or Marceline?"

"( y/n ), calm down. You're tots letting your brain dial turn your fear volume up." With that he passed out.

Dammit Finn, dammit.
