HEY…WHAT'S THE MEANING OF SEX?

The borings days continued for the Mugiwara crew, as their course didn't change or drove them to any danger. Well boring for everyone except for the cute navigator and the innocent captain. Their encounter was driving them crazy for each other touch but it was too risky with everyone goofing around the ship thanks to the insane heat, and of course their confused minds didn't allow them to do anything.

Nami looked at the ceiling of her dorm. What the hell happened? She didn't have a clue, she only was playing...at first…then she couldn't stop herself. She only knew she wanted more, so much more from him. Her lust was driving her mad to the point of touching herself, thinking about her captain and the way he kissed her, including his rubbing and touch…

Embarrassed of what she had done alone, she decided she will look for him again and she will finish what they were doing days before. She was planning for her next attack, but she paused for a brief moment…did she loved him? That was the question itself and honestly she didn't have a clue either. Of course he was her precious captain, her precious nakama and all but what will happen if they have sex? Everything will go bad? She closed her eyes and slapped her cheeks…she wanted him that was all she knew "I will deal with the consequences after we´re done…"

For the other hand, Luffy's head was in the clouds. This time something more intriguing had happened to him and he wanted to explore it, to find the end of the road. It was for granted he didn't have a clue of what to do nor had the knowledge of what sex means, but that didn't unsettle him, on the contrary gave him more will to go forward. She was his friend, his precious navigator and his precious nakama so what's wrong in have sex with her? It was a nice thing right? It wasn't like he loved her? or did he?...yes guys at least the captain knew what love was. Whatever it was, he will not stop. But he will have to find out what was the meaning of sex first…

His long thinking started to attract the attention of his nakama, who were beginning to feel worried about the unusual behavior on their captain: quiet and so calm. So after deciding who will go and ask him what was wrong with a rock-paper-scissors game, Chopper, the loser, was the chosen one to interrupt the thoughts of Luffy.

"Luffy…" said the reindeer with extreme careful to not annoy the concentrated Luffy "are you ok?"

The captain didn't answer so Chopper, a little freaked, looked over his shoulder to the rest of the crew. They gave him the thumbs up, sign to continue persisting. He gulped and asked again, this time a little louder…well literally… he shouted, scaring the crew and waking up the captain.

Luffy widened his eyes snapping out of his thoughts. He nodded to Chopper and smiled, "I´m alright Chopper". The calmed tone he used and the unusual smile worried the doctor more and freaked out the crew that gasped in unison as soon as they saw the smile. The ones who stood normal were Zoro, who had the very exact idea of what was happening and was laughing at his hopeless captain and Robin who only widened her eyes surprised.

Chopper started to harass Luffy with a lot of question about his health and body condition, asking him if he wanted to call a doctor for him.

"YOU ARE THE DOCTOR!" said everyone in the back

"Oh! That´s right! I will examine you Luffy!" the reindeer said but Luffy was focused in another thing, the book Chopper had in his arms, which had a woman and a man for cover. The curiosity and need to satisfy his own self hit him again and he couldn't help but ask the doctor what was that.

"This? This is my human anatomic book" said chopper grinning "I'm studying more about humans and their way of reproduction… did you know they call it sex? You know it starts when the man spermatozoids enter at the woman…"

But Chopper was silenced by the crew's horror shouts. However, the most horrifying thing was what the captain said next.

"Can you lend it to me?"

Everyone almost died when they heard that, including Zoro, who hit his head with his hand and murmured how moron and obvious he was.

And then silence on the ship. Due to the sudden question of Luffy and his weird behavior, also his concentration on trying to read the book, everyone decided to go on a meeting without him on the navigation room…well Ussop was the one who dragged all of them there, including Nami, who was still confused.

"So what's going on?" said the orange girl annoyed by the fact she had to interrupt her plans for that stupid meeting.

Ussop started to freak out again "You should have seen that Nami!" said Ussop "I think the world in ending!"

"What!"

"No the world is not ending" said Brook "it's just having a twisted and mad turn…I think it's the sun fault…or maybe his bones are weak…hohoho"

Nami couldn't understand anything. She was trying to ask but she was interrupted…again.

"I think he is sick!" shouted Chooper "We have to call the doctor!"

"YOU ARE THE DOCTOR!"

Sanji lighted a cigarette and was the one who took the word this time…"Well for a guy of the same mentally age Luffy has…I think it's perfectly normal…and human"

"It´s not normal...it's SUPAAAAAH!

"It's not normal neither super! It's horrible…why Luffy its thinking like that? Ussop shouted again.

Nami was still confused and in search for some answers she looked at Zoro and Robin whom hadn't spoken all the time they were there. Zoro was sleeping and Robin smiled at her…

"Well miss navigator" said the archeologist "Our captain had been weird lately" Everyone shut their discussion after Robin talked. "He had been interested on the human reproduction, he asked to our doctor if he could borrowed the book of that theme"

And that's when Zoro opened an eye, and looked at the culprit of everything.

Nami froze but soon regain her composure. Fortunately, this wasn't noticeable and she started to act like nothing had happening. Only the sharper eyes of Robin and the insane senses of Zoro noticed the slight change in her behavior. And like the swordsman had predicted soon, while the discussion of "where is the normal in the whole situation" keep going, Nami left the navigator room and went to where the captain was.

She found him laying on near her mikans garden alone and looking at the moon, hypnotized by the beauty of the night. On the contrary of the mornings, the nights were cooler, windy and relaxing. She just sat beside him hugging her knees and looked at the sky with him. After a while, she started the conversation.

"So…you wanted to know what sex was huh?"

"Yeah…but I couldn't understand most of it…" said Luffy still looking at the stars.

Nami looked at him "Why?"

"Because it had a lot of words I don't know" said him honestly.

Nami was going to hit him but sighed "I was talking about why you wanted to know what sex was"

Luffy kept quiet for a brief moment but continued "because Zoro said that that was what we almost do the other day" he was still looking at the stars. He didn't look at her not even once and she started to feel annoyed.

"Because you were thinking about doing it with me?" said Nami frankly without even blink.

Another pause that felt like an eternity…"Yeah…"

"Why?"

He didn't answer…he didn't have an answer. Why? He would like to know why…he only wanted to do it with her that was all. He hadn't had hidden feelings.

Suddenly, Luffy sight was obstructed by Nami's face. She had positioned herself on top of him, supporting her body with her arms and knees. Her legs intertwined with his legs, her orange hair was hanging down from both sides of her face. He didn't move not even blink he only looked directly to her eyes. The navigator leaned her body to kiss him.

The kiss was lazy at first but soon the lust they had been keeping insides their bodied and minds started to take over them. Nami slide her tongue inside his mouth tasting him and he did the same, battling with her tongue while his hands were caressing her thigh and her back. Nami broke the kiss with a tread of saliva between their tongues.

Then she stood up and looked at him "Well I guess if you don't tell the reason I don't have the desire to do it". After saying that, she started to walk away.

Mean…this woman is the devil itself. That´s what Luffy thought, while closing his eyes.

Nami was disappointed. She wanted to stay but she also wanted to hear why he wanted to have sex with her. Did he loved her? Nah…that was impossible, he liked her only like her nakama and navigator. So it was his lust only…she couldn't help but feel a knot in her stomach. She stopped in front of a wall and sighed, "what a contradictory self you have Nami" said to herself.

Suddenly a hand slammed the wall from behind her, locking her up, preventing her from moving and squeezing her against the wall. Everything was so quickly so she didn't have time to react. Her eyes where wide open, her back was facing the person who had stopped her. She felt his hot breath on her neck and started to get aroused "Nami…If you want an answer I don't have it…" said Luffy sinking her head on her soft hair, with a pained and desperate look.

"But…" Luffy took her hand and turned her around so she can face him "I will tell you this" he kissed the palm of her hand "right now I want to do it with you…I don't care why, I just want to" Nami blushed wildly as Luffy get his face closer to hers "so the me who run after you…it's at his limit…" and then he assaulted her mouth, kissing her passionately, giving her a break minded kiss.

His leg separated hers and she moaned on his mouth. Her hands started to move quickly tracing his scarred and toned chest and his red shirt fell from his shoulders. Soon Luffy hands disposed off her bikini top and started to touch her soft and creamy breasts while his mouth had left Nami's and was kissing and nibbling her neck. Soon his tongue found its way to her breasts and erect nipples. She moaned once again when she felt his moist kisses on her sensitive spot and he smirked against her skin.

Aside from his clueless self, the captain knew he was arousing her and he enjoyed the feeling of have tamed the beast.

Soon Nami legs gave in and her strength drained out from her body as she slid down to the floor, but Luffy and his always alert reflexes moved with her so she landed on his lap with her legs on both sides of his body. Luffy continued with his caresses but soon he realized he didn't know what to do next so he returned to her mouth.

Nami looked at him, his sweet but sensual kisses and his careful touch were too much for her. Almost desperately and without breaking the kiss (only for air) she went to his sash and untied it, to then unbuttoning his pants. Her hands were moving faster but Luffy's heart started to pound faster and his body started to react anticipating her moves. Soon his hand did the same moving through her breast and naked belly, arriving at her skirt. He lifted it up and his fingers found her underwear.

She moaned when she felt his hand playing at her inner part. Luffy's fingers went inside her underwear and felt her wetness, something that exited him. Soon he started to play there with his fingers, going up and down. He unconsciously pressed her clit, and thanks to that Nami broke the kiss moaning out loud.

Surprised, Luffy pressed it again and Nami moaned once again. His movements went faster and more accurately as he looked at her reactions: the girl was moaning sensually and loudly at him, craving for his touch. He liked her sounds. He took the hem of her underwear and ripped off.

The captain found himself wanting to do his navigator and knowing what to do, mostly thanks to his instincts. That was his conclusion, to do her wildly without taking care for the consequences. So, desperately, with one of his hands he took one of her thighs and with the other he took his member and placed it on her entrance. Nami moaned when she felt his hardness on her clit.

"Ahh…how…you know…?" She said with the little of conscience she had.

"Don't…don't think I'm that dumb…" Luffy smirked sexily and pushed his member inside Nami. She moaned and arched her back while he grunted when he pushed himself slowly on her tightness. Then he took his hat and pushed down on his head, the same remark he do when he is about to fight with a fierce opponent. Nami almost came when she saw him do that but contained herself. Soon they started to move and felt all kind of new sensations.

As for Nami this wasn't her first, she had done it, a rough and horrible sex. But this time it was different. He was sweet and roughly at the same time, mostly caring for not only her body but for her as a person. Afterall it was the captain and he was doing her madly, thing that aroused her more. And Luffy…well it was his first but… as a fast learner he is…soon he was moving like a pro with a lot of stamina and adrenaline in his body, following only his instincts.

His thrusts became faster and deeper and his touches smoothly complimented the pleasure Nami was having. She crossed her arms around his neck and kissed him, slowly pushing her firm and bouncing breasts against his naked chest. She was reaching her climax and he felt the tightening in her walls.

"NAmi…" his lips brushed her soft neck as he buried his face on it groaning, he was reaching it too.

Nami fisted her loose red shirt with one hand and with her other dug her nails on his bare skin. "Lufffy..!" and climaxed.

And Luffy do the same but inside her.

They stood there in that position hugging and panting, trying to gain some air for their lunges but soon they heard steps coming to where they were. They exchanged a horror look, at least they both understood that this was a secret of only them, but Nami panicked. Luffy grinned, took off his shirt and put it on her as he separated from her and stood up, trying to arrange his clothes.

Nami looked at him and stood up barely, still trembling a little. Ussop appeared on the garden.

"Oh there you are!" said the sniper at the couple, clueless of what had happened between them "Dinner is ready!" said Ussop enthusiastically hopping for Luffy return to his normal self.

For his delight Luffy grinned like always and shouted "MEEEEEEEEEEEAT! I'M STARVING!". Soon Ussop and he were flying to the kitchen happily.

Nami sighed and smiled, it was expected he would be starving after all they had done. She blushed madly and looked at the red shirt she was wearing, it had his scent. She started to walk to the kitchen but soon remembered her outfit, Luffy's shirt and she without underwear, maybe Ussop was dumb but the others not so dumb. She decided to go change…

And look for the pills she had brought for this kind of emergences, she wasn't planning on having baby captains around.
