Chapter Text
Sitting against the mast, Trafalgar Law watched the game of Tag being played by the three youngest members of Monkey D. Luffy's crew as they ran around the deck of the Thousand Sunny.
Ignoring the complaining from Caesar Clown and the apologizing from Usopp for tripping over the kairoseki-bound scientist, the Heart Pirate captain didn't want to admit to himself that he had spent most of the game surreptitiously watching the Mugiwara's raven-haired captain from beneath the brim of his spotted hat. Handcuffs rattling as he shifted, Caesar shouted at Usopp for stepping on his stomach during the game, Usopp's voices rising in apology. In a vain attempt to calm the pair, Chopper's voice only added to the cacophony. Law closed golden eyes against the noise when Luffy swung down from the crow's nest to take a seat next to him against the mast.
The younger man was silent for an uncharacteristically long time, so long that Law thought that despite the noise, Luffy had dozed off in the hot sun. Law had also began to drift off when Luffy finally spoke, startling the Heart Pirate captain into full wakefulness.
"Torao. We're allies, right?" Luffy asked, bringing his arms up behind his head and settling once again against the mast.
"Yes, that is correct, Mugiwara-ya. Why do you ask?"
The younger captain's face screwed up into what Law could only mentally describe as "an attempt for deep thought from someone not used to deep thoughts" while he waited for Luffy to answer. Meanwhile, Sanji had come out onto the deck to shout, "if my souffle falls, I will kick each of you shitty kids in the head!"
"Well...I was thinking...we should do something to prove that we are friends, right?" Luffy said, staring intently at a fluffy cloud.
Dreading where the unpredictable raven-haired man's mind was heading, Law took in a deep breath. "Alliances doesn't mean friendship...." he began.
"We should have sex," Luffy interrupted.
Law could only stare at Luffy. "...What?" he managed to sputter out.
"We should..."
"I heard you, Mugiwara-ya. But how does one go from alliance to sex?" Law queried, his mind still reeling.
"If we have sex and become lovers, then that means we'll be together forever, right?" Luffy answered, turning to stare at the blue-haired captain as if he was a idiot.
"...Not necessarily..." Law said, unable to stop the blush that colored his tan face.
"Doesn't matter. I want you as my boyfriend," Luffy said, gazing intensely into Law's eyes.
Law felt himself melt slightly as he returned the brown-eyed stare, his heart pounding. It was at that moment he finally admitted to himself that he was definitely attracted to the raven-haired man, which also explained why he had watched the game of Tag in the first place.
"Uh..." he managed to stammer out before Luffy did the one thing that made Law melt completely.
Luffy smiled. At him.
Like the incoming tide hitting a beach, Law felt Luffy's body heat hit him mere moments before the younger man leaned over and kissed his cheek. Salt and wind-chapped lips brushed briefly against his 5 o'clock shadow, wiping all rational thought from his brain as it tried to catch up with what was happening.
"Aw man!" Law heard Usopp cry out right before a female voice added from the mikan tree grove, "Usopp, you owe me 10,000 beli!"
From his place on the opposite side of the ship Ceasar shouted, "Stupid long-nose, how could you not see that Law has been watching Mugiwara run around since you three morons started playing your stupid game!"
Luffy leaned back and smiled again at the Heart pirate. "We're dating now, Torao. Okay?"
All Law could do was nod.
Law felt rubbery fingers caressing the back of his hand. Looking down, he saw chewed fingernails and calloused knuckles as they lay across the back of his own slender hand. Looking up, his eyes locked onto Luffy's once again. The two stared at each other as if unsure before Law swallowed nervously and slowly turned his hand over to gently yet firmly lace his fingers with Luffy's.
The smile that graced Luffy's face made all the previous ones pale in comparison.
