Doflamingo sighed while checking the time again. He was late for work, and his alpha wasn’t here yet. For a second he pondered on calling Luffy to ask when he’d arrive but didn’t dare do it. Besides, the alpha would most likely just get here even later as a reminder of who was in charge. It wasn’t worth it, not even his important meeting was worth the pain and humiliation he’d get for questioning Luffy. He tapped his foot impatiently, he wished he could go alone but he didn’t even have the keys to any of his cars anymore. Hell, he doubted he’d dare to disobey a direct order even if he still had them.
His musings stopped when the vibrator in his ass came to life and he couldn’t hold back a moan. Leaning on the wall, he brought a hand to his dick. He had his cock ring on today, but it’d still be better if he—
Someone cleared their throat behind him and he turned around to see one of his servants looking at him with reproach. Doflamingo’s hand left his dick as if burned. Damn it, now his alpha would know he touched himself without permission.
Just like he thought, the servant wrote something on her phone and waited next to him. Doflamingo made sure to put his hands away from his dick and leaned back on the wall with trembling legs. The vibrations got stronger and he moaned again.
The door opened and the alpha strode in as if he owned the place. Considering how his servants behaved, he may as well.
The servant next to him bowed low to Luffy, “Welcome back, Young Master Luffy.”
Luffy smiled at her and waved, ignoring Doflamingo for now, “Hi Agate! Has Mingo been a good bitch?” Despite asking for him, Luffy didn’t even glance at him, not even when Doflamingo whimpered at the vibrations getting stronger again.
Agate frowned, “I am afraid he hasn’t, Young Master. He touched himself without your consent a few minutes ago. I had to remind him of his place.”
Frowning, Luffy finally looked at him, “So you thought you deserved to stroke your clit without permission, Mingo?”
Doflamingo nodded, not looking at Luffy in the eye. The slap echoed in the room and turned Doflamingo's head and back around, making his ass hit the wall, thrusting the vibrator deeper inside him. Moaning, Doflamingo fell to his knees, panting to adjust to the new angle.
A foot pressed on his dick and Doflamingo whimpered in pain and pleasure. Luffy gripped his hair and forced him to look at him.
"Alpha I—" Luffy took a bright pink collar from his pocket and put it on Doflamingo's neck.
Like every time Luffy put it on, it was difficult to think with it on. The leash followed soon and Doflamingo panted, waiting for the order.
"On your hands and knees." Doflamingo was quick to obey, Luffy grinned and tugged at his leash "Crawl."
Luffy started to walk and Doflamingo crawled behind him, whimpering when the movements made the vibrator change angle constantly. He didn’t even care he was wrinkling his expensive Armani suit, he just wanted to come. Not that Luffy would let him, not when he touched himself without permission.
Like always, Luffy waved and greeted by name every servant they met on their way to Doflamingo’s garage. The servants smiled and bowed low to Luffy in a way they never did to him anymore. Doflamingo was the one who used to be the Young Master, now he was just Luffy’s bitch. No. No, not yet. He wasn’t bitched yet. He could— A harsh tug on his leash made him choke, Doflamingo’s tender cheek landed on the floor and he winced. Right, he’d stopped crawling. Damn it.
Another tug made him go back to crawling and soon Luffy was choosing which of his cars they’d use today. Being thrown roughly to one of his Ferrari’s driver’s seats. Doflamingo was vaguely aware of Luffy taking off his leash and covering his collar with a pink scarf. So he wouldn’t take it off today. He’d have to be careful.
The ride to Doflamingo’s company was hell like always. The vibrator didn’t stop for one second and every bump on the road made him moan like a whore. Luffy filmed everything, spending all the ride with his hand down Doflamingo’s pants, tugging harshly at his balls and stroking his dick until he wanted to cum so badly it hurt not to. Even then, Luffy didn’t stop until they parked on his private spot.
Knowing what would come now, Doflamingo unbuckled his seatbelt as fast as he could so Luffy wouldn’t get angry. Doflamingo didn’t have time to do more than bend over on his side before Luffy grabbed the back of his head and shoved it on his clothed erection.
Speaking fast, Doflamingo looked up, vaguely aware of the phone filming him, “Alpha, I have an important meeting—” Another slap silenced him and he looked down, showing his neck in submission.
“I don’t care, you won’t leave until you’re full of my cum. Now get to it.”
Nodding, Doflamingo grabbed the fly of Luffy’s shorts with his teeth and gently pulled it down, freeing his alpha’s cock. It was as big as always, heat pooled on his stomach when he saw it, mouth watering as he’d be trained to, and he took the head in his mouth. Luffy let him do as he wanted for a few seconds, before shoving the rest of his dick down his throat.
Doflamingo groaned around Luffy's dick as the alpha relentlessly used his mouth as a fleshlight. He was rough, thrusting in and out of Doflamingo's mouth while he choked and drooled. Saliva ran down his chin and his jaw ached from the abuse. The only thing in his mind was the constant pounding of the alpha's cock in and out of his throat. He heard a dark chuckle above him and the cock in his mouth grew. It went deeper. He gagged and teared up as the cock extended down his throat. He tried to relax and just take it, but he kept choking and crying until Luffy made his dick a bit shorter, just enough for Doflamingo to breathe when Luffy pulled back.
Losing himself to the feeling of his throat being used, Doflamingo closed his eyes. An irritating sound interrupted his thoughts and Doflamingo took a second to register it was his own phone. Why were they bothering him— the meeting! Damn it, it was a very important meeting he couldn’t— he couldn’t leave until his alpha allowed him. Sucking as much as he could in his situation, Doflamingo did his best for Luffy to cum soon. He had to go to this meeting.
Laughing at him, Luffy shoved Doflamingo’s head down his dick until Doflamingo’s nose was touching his alpha’s pubes. Doflamingo choked, tears ran down his face but he didn’t struggle. He had to go to that meeting and for that he needed Luffy to come as soon as possible.
It seemed Luffy didn’t care, because he took his time before his knot expanded at the base of Luffy’s dick and cumming so much down Doflamingo’s throat that he could feel his stomach expanding a bit. Well, if it was only once then it wouldn’t be obvious, he still could go like that— Luffy’s dick was still hard.
Doflamingo’s resigned eyes locked into Luffy’s mocking ones as Luffy kept thrusting. A hand on his neck made Doflamingo choke again, black spots danced in his vision and Doflamingo couldn’t stop choking. Only when he was about to pass out, Luffy took his hand off his neck. Luffy’s foot touched his dick through his pants and Doflamingo cried in pain and pleasure. His dick throbbed but the cock ring didn’t let him cum and he sobbed in frustration.
Luffy laughed again and he groaned as he came in Doflamingo’s throat again, knotting his mouth again. This time, the cum expanded his stomach too much for it not to be obvious what happened. Doflamingo closed his eyes in defeat.
That was all Luffy needed for him to drag Doflamingo out of the car and bend him over the hood of his car. Before Luffy could rip his pants off, Doflamingo opened them and pushed them down his ankles, spreading his legs as much as he could in his position.
Chuckling, Luffy kneaded his ass before slapping it roughly, making him moan loudly. Doflamingo didn’t dare to cover his mouth, though. He knew what Luffy thought of that and he wouldn’t risk it so he just bit his lip, drawing blood.
Luffy played with the vibrator for a while, taking half of it off and shoving it whole deep inside him in one go. Doflamingo soon forgot about where he was and moaned without restraint. Only then Luffy took the vibrator off and shoved it down Doflamingo’s throat before thrusting his dick deep in Doflamingo’s ass in one go.
The vibrator didn’t do much to cover Doflamingo’s scream as Luffy’s dick touched him way deeper than the vibrator, touching his prostate constantly. Doflamingo moaned and drolled, saliva falling to the hood of his car. All he could think of was the dick moving deep in his ass, stretching him so much it hurt in the best way. Doflamingo was so full right now, his suit was getting tight on his stomach, but he was too used to that for it to be anything more than an annoyance.
A low groan next to his ear and he shivered as cum filled his stomach again, the knot expanding more than it should be possible. Doflamingo cried and sobbed, struggling to get free. It was too big! He couldn’t take it. Doflamingo tried to speak but all it came out were babbles. Luffy chuckled and shrank his knot until it was barely there, Doflamingo dropped on the hood, exhausted.
After that, everything was a blur, he knew Luffy knotted him a few more times after that, but he didn’t remember how many. All he knew was that the plug was back and he was too full.
Doflamingo never made it to the meeting, or to his job for that matter.
