Pair: Trafalgar Law X Monkey D. Luffy

"Sto-p! Ngghh!"

"Be quiet! Do you want your entire crew to wake up!"

"Bu-but it's … you're fault."

"Ssshh… It wasn't mine. It was yours, Mugiwara-ya."

"Aaahh.. St-stop! Tra-… nggh."

'Shit! What the hell am I doing?!' Law thought to himself as he assaults the Straw Hat captain in his watch post.

Law and Luffy just got back at Sunny-Go from defeating Pirate Breed's ship and taking back Ceasar Clown. It was Luffy's turn to do the night watch so Luffy is staying at the bird's nest. Trafalgar Law, a Shichibukai, the man who saved his life and the man who he formed an alliance with, creep up on him while sleeping. And now, at the middle of the night, unspeakable things are happening between the two pirate novas of the worst generation.

"Sanji? What's for dinner?" Luffy shouts from the deck as he run towards the kitchen to look up on Sanji.

As the door opened to the dining room, Sanji was preparing the table, arranging the dish in a class manner. He then answered, "We have pork and veal meatballs with mushroom sauce, creamy pumpkin risotto, mixed tomato salad with pomegranate dressing and for the ladies, I made a special chocolate pavlova with raspberries, Bon appetite!"

Enticing like always, Sanji presented his cooked meals to the crew. The Straw Hat captain, like always, did not understand what Sanji said and just grabbed on whatever he can grab first and eat, followed by Chopper, Brook, Usopp and Zoro whilst Robin and Nami are slowly sipping their tea. Across the table, Frankie sat, drinking his cola whilst holding on a plate of meat and cake. Besides him sat Kin'emon, a swordsman from Wano country who tagged along with them whilst going to Dressrosa with his son, Momo. Trafalgar Law, sat across Luffy, eating slowly and quietly, which at the same time stealing glances at the Straw Hat captain.

As boisterous as ever, Luffy continues to stuff his face with meat and cake left and right, stretching out his rubber arms to reach at the opposite side of the table bumping into Zoro's sake and spilling it. Argument broke out. He got hit by Sanji in the head and was yelled at by Nami like always for being such a messy and crude eater.

By the time dinner ended, Chopper helped Sanji clean up the dining table and had Usopp wash the plates. The rest of the crew headed towards the deck and brought Ceasar his share of food. Time pass, everyone went to their sleeping quarters leaving Luffy at the bird's nest for tonight's watch. For about an hour or so, Luffy fell asleep, sprawled in the soft red colored sofa forgetting that he's on night watch. Amidst his slumber, Law creeps in and looms over his body with a Kairoseki hand cuffs on his hands. He then cuffed Luffy's arms above his head and that earned him a low groan. Sereval minutes later, Luffy groans in his sleep, sweating, out of breath.

He slowly opens his eyes and gasps, "Wh-what's going on? I- I feel week? Urrgh"

"You're finally awake, Mugiwara-ya!" Law greeted as he stood across the room leaning against Zoro's gigantic dumbbells that Zoro uses for his exercises.

"Tra-guy?"

"You are too trusting Murgiwara-ya. You are so careless, sleeping so soundly while you should be on watch. Didn't you learn how to use Haki, huh? You could've avoided being cuffed like that." Law said as he walks nearer Luffy, pointing out the Sea stone hand cuffs on his wrists.

"A-re? When did this happen?" caught in between pants, Luffy tries to shake off the hand cuffs as he tries to sit up. "Say.. Tra-guy? Can you remove this? I don't have the strength to move."

Law looms over Luffy's body and smirks. He used the sheathed end of his sword as an extension of his hands to raise Luffy's hand cuffed wrists and lifts them in the air. Wondering what Law is doing, Luffy opens up his mouth and was about to speak when Law clashed his lips with his and stole a kiss. Taken a back, Luffy groans. Too weak to even retaliate, he let law pick up his pace and play with his tongue. As soon as Law let goes of Luffy's lips, Luffy pants, blushing like mad.

Smirking, "Who would have thought, you tasted so sweet, Mugiwara-ya!?" Law said as he licks his lips.

Luffy blushed even harder. He stares at Law with watery eyes, panting, sweating and his wrists in the air, still cuffed. He said, "Wha-t are yo-u do-ing? G-get this o-ff of me!"

"Ssshhh. You don't have to yell. Although, I really do want to hear you raise your voice, Mugiwara-ya!" Law said lucidly as he uses his finger to trace Luffy's collar bone. A shiver went down Luffy's spine. But instead of awkwardness, he purred to Law's touch and mewled. He was surprised. Both of them were. Luffy did not expect this kind of sensation, just from having his collar bones traced so softly… so lightly, as Law did not anticipate this kind of reaction from the Straw Hat Captain.

Law smirks with excitement whilst Luffy feels threatened. Law puts down his sword and pins Luffy back down to the couch, making a thud sound. Luffy lay on his back, wincing and groaning. As he opens his eyes, he felt Law licking his lips once more whilst Law's right hand starts to caress his body.

"Wa-wait! Mnnff… St-op!" Luffy hiss. As he opens his mouth, Law kisses him again. Playing with his tongue once more as Law hungrily sucks and explores his mouth. Luffy moans.

Startled by the sound he made, Luffy closes his eyes and blushes like a fully ripped tomato. He squirms. He can feel Law's feather-light touches sending shivers in his spine. He could not help but moan.

"I must say, Mugiwara-ya, I really did not think that you already have experience in this." Law whispered teasingly by his ear.

"Yo-u… you're wrong! I- I… Mnnghh." Luffy said in between his breathe as he felt Law pinched his nipples.

"I am not wrong. Do not forget, Mugiwara-ya that I am a doctor and I know my patients body inside and out." Law said as he traces the scar on Luffy's chest. Luffy remembered that time when he almost died and he was rescued by Jinbei and Law. He heard Law speak in a low voice, "…and you were once my patient. I saved your life."

"Ngghh! Wh-what do you want?" Luffy tried to speak up as he glares at Law.

"No-thing. I just wanna have some fun with you." Law smirks as he fluidly pulls down Luffy's pants. "Heh.. I guess you're body is really enjoying this, Mugiwara-ya." Law continued as he grabs Luffy's fully erect member and started to stroke it.

"Ahhh… St-stop! Mnnghh!"

"Nice reaction! So you really have experienced this before. I wonder…. Did you perhaps do it yourself? Or someone else did it for you?" Law said as he tightens his grip, making Luffy cry out in pain.

"Ahh.. No. Yo-u're wrong! I… I.." Luffy repeatedly said as tears trickle down his cheeks.

"Don't lie to me. It is blatantly obvious. You're reactions says that you are not new to this." Law answered as he entered his middle finger in Luffy's hole.

"Aaaaahhhh!" Luffy cried out in pain from the sudden intrusion in his hole. "St-op! P-ple-ase.. Ngghh.."

"Was it the cook? Or is it your first mate?" Law whispered by his ear.

Startled, Luffy stopped crying for a moment and tried to look at Law's face and he found a really scary look on his face. It was the first time he has seen Law look so angry, not like he has known the guy for long. He felt scared. He of all people got scared of another. He tried to open his mouth but was only greeted by another rough kiss.

"So? Who was it?" Law insisted.

"You're wrong! There was no one. I have never – " as Luffy was about to retaliate once more, he was stopped as he felt ice cold hands choking him.

"Don't lie!" Law said as he stared at Luffy with angry look on his eyes. "I know. It must've been your swordsman. After all he is your first mate. I'm correct, aren't I?" Law continued as he tightens his grip around Luffy's neck.

"N-o.. ngghh" Luffy insisted, coughing and out of breath.

It was painful. Luffy is hurting not just because his body is being toyed with but he feels like his heart is being crushed and he has no idea why. As he was being violated by who he thought to be his friend, he cried.

Law licks the trickles of tears from his cheek as he said, "Go on! Cry. But I will not stop just because you do."

"Pl-ea-se. E-nough. I-I don't like this. St-op." Luffy pleaded.

Deaf to his ears, Law pretended not to hear anything. He removed his middle finger from inside the Straw Hat captain only to replace it with his own member. He thrusts. Luffy groans. He could care less as to what the Straw Hat captain will say now. All he wants is to ravish this young lad and he does not know why.

He impaled himself inside him over and over, making Luffy bleed. He licks, he bits and sucks on whatever part of Luffy's skin he could get a hold off, making him bleed. Luffy grunts and came loads of times but this does not seem to be enough for Law at all.

Law turned Luffy around in all fours as he thrusts in Luffy deeper than before. Luffy arched his back and moaned. Finally, he heard Luffy moaned in pleasure. He has found it, the Straw Hat Captain's pleasure spot. He embraced Luffy from behind and used his free right hand to stroke Luffy's neglected member once more, earning a soft moan from the boy.

"Sto-p! Ngghh!"

"Be quiet! Or do you want your entire crew to wake up! Not that I care." Law smirks at Luffy.

"Bu-but it's … you're fault." Luffy said in between his pants.

"Ssshh… It wasn't mine. It was yours, Mugiwara-ya."

"Aaahh.. St-stop! Tra-… nggh."

'Yes, it is your fault. Having that Breed-guy take you as a pet. Following his orders like a slave. You are mine. I shall not let anyone else have you.' Law firmly thought to himself as he continues to assault Luffy from behind.

With every forceful thrust he gets a very forceful moan, making Luffy's voice sound so horrid, so hoarse. Endless tears, drips in his face as he was forced to do things that Law orders him to. Keeping him in shackles and lay sprawled in the couch, his legs wide open for Law to see.

They have done it more than once. Twice wasn't enough. Several times? Even Ten Times… He has lost count. Luffy finally stopped crying, he felt so helpless, leaving his body in Law's hands as his consciousness drifts into space. He fainted.

Law stopped. He saw Luffy finally fainted in his arms. He pulled himself out of Luffy, laying waste of the Straw Hat Captain in the couch. He stood up, fixed himself and loomed over Luffy. He reached out for the handcuffs and removed them. He then gently lifted Luffy's right hand caressed his wrists, kissed it and said, "I will never say sorry for I do not regret what happened." He paused and stared at the teary faced captain, sleeping and continued, "You are mine, Mugiwara-ya! You are my pet alone and no one else's."

And with those last few words, Law quietly left the bird's nest, leaving Luffy naked and sprawled in the couch unconscious, drifting in the coldness of the night.

To be continued on the next chapter.
