Luffy was still heavily feeling the effects of the aphrodisiac. Law's threats didn't bother him, he was so desperate that he couldn't think straight. He longed for Laws dick. He yearned to be satisfied.

He shakily rose to his feet and staggered over to a desk on the other side of the room. He bent over slightly and rested his elbow on its surface for balance. He then used his other hand to slide his tight pants down, allowing them to fall dripping onto the floor between his legs.
Luffy dug his fingers into his bare cheek as he pulled his ass apart, revealing his hole in an attempt to seduce Law.

Luffy looked over at him.
He was watching.

"Fuck me"

"Pleaseeee"

Luffy asked enticingly, lifting his ass higher.

Law kept a straight face. Even though his expression didn't budge, inside he was going crazy. He was fastly approaching his limit. His jeans were painfully choking his erection.

"I'm begging you"

Luffy pleaded, spreading his ass even further so that Law could see inside of his hungry, wet ass hole.

Law stood up and paced toward Luffy.
He grabbed Luffy's head and slammed it into the desk, pinning him down.

Luffy smirked, he was finally going to get what he wanted. He had won this time.. at least for now.

The pain that shot through his skull intensified his need for pleasure, causing a rush of excitement to engulf his entire body.

Law undid his jeans and released his giant member. It was erect to its fullest. The tip was swelled and throbbing, and thick veins jumped beneath the skin of his hardened shaft.

He rubbed it between Luffy's ass cheeks, sliding it up and down his drenched crack.

Luffy's gut coiled with anticipation as Law aligned his cock before thrusting into him.

"WAHHHHH~!"

His dick was so hard, it felt like a rock stabbing Luffy's inner walls.

"Don't move .. Yet!.."

Luffy groaned painfully.

Law ignored him, instantly pounding Luffy's ass.
He hammered into him violently at an unbelievable pace.
Luffy could feel his insides re-arranging themselves around Laws dick. His ass now belonged to him.

The sound of loud wet slaps rang in Luffy's ears as Law reached into him deeper and deeper, hitting against his prostate every time.
Each thrust was faster and more forceful than the last.
Luffy began to tense up.

"GUNNAAAA...!"
"N-nn... AHHHH~!"

Law tore into Luffy as deep as his tight little ass would let him before flooding his good spot with cum.

Luffy screamed at the top of his voice as he felt Law pour his liquid inside him, before spurting out his own juice.

Law closed his eyes and groaned with relief, his dick still buried deep inside of his ass. Luffy lay over the desk in front of him, his hips still twitching from his climax.
Luffy's insides spasmed around Laws sensitive cock, causing him to whimper.

He loved hearing Laws voice, it was the only visible crack in his tough guy act.

"So.."
"Are you ready.."

Law panted, snatching hold of Luffy by his shoulders and lifting his upper body.

"..for round two?"

He pulled his dick out of Luffy's cum filled ass before ramming it back in again, even deeper than before.
Luffy's head fell back as he let out a long painful cry.
He felt a dribble of Law's cum run down his leg as his dick squished into him.

Law held the back of Luffy's thighs and picked him up.
He held Luffy in his arms, lifting his body up and down on his dick.
Luffy looked down, between his spread legs, and watched Laws thing slide in and out of him.
Law began kissing his neck.

"Soooo deep.. Like this..~"

"Feels .. So good!"

Luffy whined.

Law bounced Luffy on his dick, rapidly increasing his speed.
He began sucking Luffy's neck, digging in his teeth. He applied more and more suction, leaving small purple bruises all over his neck, until finally sinking his teeth into Luffy, piercing his skin.

Maybe it was the drugs, or maybe it was just that Luffy had simply become accustomed to pain during sex. Or maybe Law had made him realise his masochistic nature. Whatever the cause, feeling the sharp sensation from Laws teeth breaking his skin gave Luffy a tingling rush of overwhelming pleasure.

"Againnn-"

Luffy called out.

"Bite me againnn-"

Law didn't like being told what to do, but Luffy's wishes appealed to his sadistic side.

He sunk his teeth into Luffy again, only this time in his shoulder.
Luffy let out a small yelp.
Law bit Luffy over and over. Drawing blood each time. Even though it hurt, all pain Luffy felt was overcome by pleasure.
Law continued to fuck Luffy, whilst leaving blood drawn imprints all over his back ,neck and shoulders.

It wasn't long before Luffy succumbed to bliss once again, squirting all over himself.

Law used Luffy, over and over, abusing his tight ass.
It was no longer his asshole, but a sex organ. It's sole purpose was to suck out everything Law had.
Law switched positions and fucked Luffy into submission, forcing him to climax every time.
Luffy lost count of how many times he came before Law.

Eventually Law gave in, shooting another hot load inside of Luffy, completely filling him.

Law swiftly pulled out without warning allowing everything he dumped inside of Luffy to gush out of him.

"UUU-Ahhhh!"

Luffy bent over, resting his hands on his bed.

"Is there any more left inside' you?"

Law asked.
Luffy responded rapidly, shaking his head. But Law failed to take any notice.

"It's okay, I'll get it out for you."

Law hooked his finger inside of Luffys cum filled ass, and tugged on his swollen hole, stretching it out.
He then jammed four fingers into him.
He began spreading and scissoring his fingers inside of Luffy, opening him up even more before adding in his thumb.

"N-NOOO!"
"IM GUNNA BREAAAK-!"

Luffy cried out.

"Don't be silly, you're the rubber man remember? No matter how far you're stretched, you will always go back back to normal after, right?"

Luffy couldn't argue, he knew Law was right. But he also knew he couldn't agree. It's too convenient for a sadist like Law. For him to be able to destroy Luffy's ass to his hearts content and still have the pleasure to feel like he's fucking a virgin every time they have sex.

Luffy's ass swallowed Law's entire hand. His hole sucked on Law's wrist like it was trying to gobble his entire arm.

"Such a greedy hole.."

Law teased, curling his fingers over, forming a fist inside of Luffy's passage.

"NO NO NOOOOO!"

Law twisted his fist, tearing Luffy's insides even further apart
, pushing on Luffy's stomach from inside of him.

Luffy could feel it coming, but he couldn't find his voice.
He stood there, helplessly waiting as Law ruined his ass, churning his insides with his fist.

Luffy threw his head back as his eyes rolled into the back of his head.

A loud gushing sound echoed throughout the room. Luffy let it flow out of him and stream down the inside of his legs.
Law watched as it sprayed off of the floor, soaking the bottoms of his jeans.

Luffy fell onto the floor, panting with relief.
Law squatted behind him, and whispered in his ear,

"Oh look, you've made another mess on my clothes..."

"..Drink up!"

Law commanded, pushing Luffy's face into his mess, his fist still tightly packed inside Luffy's ass.

Luffy leant forward and lapped at the floor like a dog, dragging his tongue through the puddle that surrounded him.

Law was completely satisfied, seeing Luffy so obedient.
He had completely claimed him.

He straightened out his hand and slowly tugged it out from Luffy's hole.

Law then stood, holding Luffy's head up by his hair, like a puppet being held up by strings.

Luffy knelt in his own piss, with his ass hole gaping open.
His arms dangled lifelessly at his sides. His tongue hung out of his mouth like a dog panting for air, and his eyes began closing on themselves as he drifted in and out consciousness. His hair was slicked to his face, drenched with sweat and other bodily fluids.

He too, was completely satisfied.

Law let go of his hair, allowing him to fall lifelessly back into his mess.

Law turned on his heels and headed for the door.
Luffy suddenly erupted with anger and burst back to life. He couldn't believe Law was just going to leave him again.

"YOU CANT JUST MESS ME UP LIKE THIS AND LEAVE PRETENDING EVERYTHING'S NORMAL!"

He cried out, his voice was still shaky but his anger was over powering every other sensation in his body.

"WHEN ARE YOU GOING TO START TAKING RESPONSIBILITY!"

Law stopped, with his back still to Luffy.

"Okay, I'll take responsibility."

He replied.

"From now on, you belong to me, Monkey D Luffy."

Without another word he proceeded to leave.

That was his idea of asking me to be his boyfriend, Luffy thought to himself pouting, slightly disappointed.
Luffy then remembered just how cool and stubborn his new boyfriend was.
A wide grin began to creep along his face, as he held his head trying to contain his excitement. He chuckled to himself and rolled onto his back, laying spread out. He let out a deep blissful sigh, like a teenager dreaming about his crush.

If he belonged to Law, did Law belong to him?

...Later on that evening...

"We'reeee back!"
"Oi Luffy, Sanji bought some food back for you to try!"

Usopp yelled

"Oi Luffy!"

The crew looked at one another, wondering where the hell their captain had gotten to. It wasn't like him to turn down food!

"Maybe he's mad at us for leaving him?"

Nami said, confused.

Eventually Luffy appeared, waddling as fast as he could toward the kitchen.

"Luffy?"
"What happened to you?"

Chopper asked worriedly.

"Are you hurt? You have cuts and bruises all over your neck!"

He fussed, trying to examine the strange wounds.

"Yeah, and you're kinda walking funny?"

Usopp joined the fuss.

"Did something happen Luffy-san?"

Brook asked, also wondering what was wrong with their captain.

Luffy dismissively answered all three of them at once,

"Trust me, you don't want to know."
