I didn't think I'd ever write a fanfiction, especially not a SMUTTY one. I'm aiming for this to be less than 20 chapters but let's see, and this isn't as happy as it seems!

Bon appetit :)

Chapter 1

When did this happen?

His hands ran over the back of her dress, from her waist to her ankles repeatedly, gaining urgency as their tongues entered the other's mouth. He felt insatiable, like stoking a fire and feeling it burn in her core. He tasted like nothing but himself and fire whiskey, a surprisingly wildly addictive taste but she could do without one if they ever continued this again.

He held her tightly by her tiny waist, seated right on the uncomfortably tight portion of his fancy pants. Their panting sounds and frenzied movements against each other filled the dark bedroom with a musk.

"Lucy…You taste so fucking good." Natsu's voice was never this deep or husky or…sexy. Immediately she felt jealous if anyone else got to hear their name from him like this. She felt possessive because there was no foundation for them to do this.

Today was graduation day from Fairy Tail Academy, and to this day both Natsu and Lucy are known as the Siamese twins, the best friends that never disconnect, the two soul partners in the most platonic sense possible. That's just what they said to each other, and assumed the other felt that way as well. Anyone with eyes can see that they are meant for each other.

Except potentially one person…

That wasn't a concern right now neither of them felt anything besides how amazing they felt in this situation. It only got better as they removed his shirt, her dress, his pants, and everything in the way from feeling so right.

When she started startled at his oversized cock, he couldn't help but smirk at her. While she was lying down looking up at him, he grabbed her wrist and covered his hand over hers on his appendage. Moving it up and down and taking pleasure in both his actions and how she looked at him. Lining it up against her wet folds he pushed it in and wanted to cum immediately, Lucy felt better than heaven. So much better but she looked like she was in a little pain.

Lucy wanted him to move but he felt so big and full, that she even regretted her orange juice from earlier because it felt like he was hitting her stomach. He waited with bated breath for something or anything from her to start moving. Their naked bodies pressed against each other and their mouths hadn't left each other since this started, Lucy kept panting in his mouth but eventually patted his pink locs and pushed up against him to signal to start.

Natsu got too excited.

"AHHHHHH fuck Natsu! That hurt! Oh my god!"

"Sorry, sorry, sorry I got too excited."

See.

They kept pushing against and inside one another but whether they acknowledged it or not, Natsu's cum came out in spurts inside Lucy and she felt like it burned and squirmed against him. He wanted to go again after seeing that sight and started thrusting inside her tight and sore passage again. She felt too tired but as he turned her on her stomach and started grunting like an animal she realized she loved how primal he was becoming.

Natsu couldn't help but groan loudly, " Fuck Lucy, I can't keep going. You feel so fucking good I love fucking you. My Goddd. Open your mouth, right now. Open it, Lucy." She was confused but did ask he demanded. She felt his large hand move from the side of her to beneath them and rub on her wet clit.

"MMMmmfmm Natsu no I'll…Ahhhh Natsu please it's too much please." She whimpered as he became more frantic but kept her mouth open naturally. He moved his hand from her pussy to her stomach and clamped at her neck then led her back to his chest. He held and choked her for a moment and Lucy realized she loved that. Turning her head towards him he snuck his tongue inside her mouth and felt himself hammering inside her.

"It's okay Lucy, I want this. I want you to cum on my cock, come on Lucy. Please. Please just do it I can't help it, I can do it." Natsu started blabbering, feeling the base of his spine tingle and getting ready to feel it again, she kept squirting all over him and his bed but he didn't care. She was sobbing against his mouth but he knew she felt as good as he did. She kept tightening and going a bit slack against him but they wanted to keep going.

He did one final thrust against him and slammed against her causing her to scream. Thank god no one was home. He felt himself release right on her cervix and some part of him hoped she took everything in the most primal way possible.

Now the two drunk graduates fell into the bed, Natsu held himself a bit on his elbow but turned to the other side of her. Lucy's big brown doe eyes looked so tired but she looked at him and he stared at her tiredly. He pulled her towards him and threw his arm around her waist as he contemplated his next words.

"I'm in love with you Lucy, you know that right." He said it with so much sincerity, that it felt like maybe he wasn't drunk and Lucy wanted to cry.

She did a little, her eyes held so many tears that it confirmed she was still drunk. "I love you too, why did it take you so long you dummy." He chuckled but pulled her even closer and fell asleep immediately.

The morning after

"Natsu why aren't you down for breakfast, I hope you didn't actual- OH MY GOD I'M SO SORRY!" Grandine had to slam the door shut after seeing her naked son stutter out a getout as he held his childhood best friend, his NAKED childhood BFF. Secretly she was happy since she wanted Lucy as her daughter-in-law but still upset at seeing her baby grow up.

Lucy was rubbing her eyes as she woke from the door slamming, " Wait what happened?" Then she noticed how naked she was, just like everyone else. Just like Natsu right next to her. "Oh my god?!" and pushed him away as she barely covered herself with his blanket. Natsu just smiled his usual thousand-watt smile towards her.

"Mornin' Luce!" He said that as if they didn't just change the dynamic of their relationship overnight. He saw her eyebrows scrunch and immediately had to react, "Don't overthink this! I told you I love you! And you said it too!" He pointed at her as he accused her.

Lucy became a new shade of pink he hadn't seen before," I know that idiot! I'm just-I don't know!" She pulled the blanket tighter and sat up but immediately regretted it. "Oh god, is this a hangover?" She felt something rush up her throat and held it back with her hand but had to get up, nakey, and run to the bathroom in his room. Natsu started laughing hysterically but then realized he was in the same boat and ran behind her.

"Move Lucy, I need to throw up." "No, stop! I'm still thro-eurghhh" "Wait Lucy don't do that it's making me-eurghhh" "Natsu no that's so gross it's makin-eurghhh" "Luce you're disgusting-eurghhh"

The two naked young teens grossly took turns vomiting into his toilet but were content that despite last night's activities their dynamic did not change at all.

OR SO THEY THOUGHT
