Work Text:

“Hey Dad?” Luffy suddenly opened the door to Ace’s room.

The 40-year old man laid on his bed, propped up by a few pillows. There’s a thick book on his lap, a pair of glasses on the bridge of his nose as he flipped a page, his eyes drifting to Luffy as he smiled. “Yeah? What’s up kiddo?”

“I’m going to hang out at the park with the others and have dinner at Baratie. I’ll be back before 9!” he said with a grin. “Can I? Can I? Pleaaaseee–”

“As long as Nami is there, I’ll trust you,” Ace gave him a dismissive wave. “Go. Do you still have money on you?”

“I do,” Luffy patted his pocket. “Alright, I’m gonna go now, they’re already outside. Bye now!”

The teenager closed the door and ran through the hallway, his footsteps loud and clear in Ace’s ears, until seconds passed and the teen was nowhere to be heard. He heaved out a relieved sigh, knocking on the wooden headboard behind him to give a signal to someone.

“He’s gone now,” Ace said, putting his book away on the nightstand.

The man who he gave a signal to crawled out of his hiding space. A blonde man peeked out from below the bed, a grin on his face when his eyes met with Ace, who adoringly smiled at the young man who had a bit of dust sticking on his cheek. He’s his boyfriend, one who he’s been dating for a few months now.

“You are one naughty dad, hiding a man under your bed like that from your son,” the man chuckled, climbing up the bed to sit in between Ace’s legs. He pulled off the blanket that laid on the older man’s lap, smiling at the hard on he was sporting. “This is such a fun situation to be in.”

“Your idea of fun is very different from what I have in mind, Sabo,” Ace’s face warmed. He couldn’t remember how this relationship he had with Luffy’s friend started.

One day, his son went to university and befriended a whole bunch of people–one of them was Sabo. He didn’t know how Luffy got to know him. Luffy had always made lots of friends, but this one, this particular blonde that apparently came from a rich household, an upperclassman of his son, has somehow taken interest in him. It felt out of place that a model student, liked by many, suddenly took interest in plain, old Ace, who was withering in his home alone, trying to keep his little family afloat.

“This is wrong.” Ace once said to Sabo, who had pinned him in the kitchen when Luffy went to his room to get something. The young man’s kiss was dizzying, filled with poison that eradicated every reason and sanity that Ace had. “I’m too old for you.”

“No you’re not. You’re perfect for me,” the blonde had said, which baffled Ace. He wanted to retort, he had to nag, to reprimand the young man for their age difference and how scandalous their relationship would be. But when those strong and firm hands are on his body, blue eyes roaming his tanned and damp skin, lips marking every inch that was exposed from Sabo’s ministrations, how was he supposed to deny this man?

Sabo didn’t let Ace reminisce too long, his long fingers slowly pulling off the older man’s pants. He didn’t know why he’s so shy in front of the blonde. Perhaps it's the shame of being twice his age, but if Ace were to make a guess, it must be because of how Sabo was eyeing him like he was prey, the way his hands glided on his thighs like he owned them, his smile oozing with certainty and confidence.

“I always loved seeing you bare like this,” Sabo said, pushing off the soft silken robes off of Ace’s shoulders. 

Cold air hit his skin and triggered goosebumps. The young man’s hands caressed his shoulders, rough and hot against his skin, slowly travelling down to his elbows, then moved to his chest, brushing against hardened nipples and rippled abs. His bright eyes observed him like he’s the most beautiful thing in the world, his tongue slipping out to wet his lips like he’s trying to hold himself back from jumping him on the get-go.

Sabo’s young, impatient. Just like this, Ace sometimes feels like the young man was trying to drag him back to his youthful days, when he was just as crazed as Sabo was. He tapped into those old, buried memories and crawled forward bravely, settling between the blonde’s legs. He leaned down, letting Sabo swallow his anticipation, his hands swiftly opening the man’s trousers to free the hardened cock that he had been eyeing ever since the blonde arrived in his room.

Ah, youth. Sabo’s libido was not something that he could underestimate. The blonde’s cock stood tall and proud, its thick girth daunting at first. But Ace was now familiar with him. “‘M gonna suck you off first,” he said, his hand pumps Sabo once, twice. Dragging the skin down to reveal the reddened and plump head of the blonde’s cock that’s wet and needy.

“Trying to tire me out first?” Sabo chuckled, a little breathless.

“Yeah,” Ace said, not bothering to lie. He gave the cock in his hand a kitten lick, tracing the veins that protruded, smiling when it twitched. “I’d like to be able to walk after all this.”

Sabo hissed when Ace popped half of his length into his mouth. The old man’s hot and wet mouth caught him by surprise. He looked amazing like this, lips wrapped around him, tongue lapping at every drop of pre-cum that leaked out of his slit, licking in a way that made the blonde’s whole body shudder. He was always able to take him all in, making Sabo groan whenever his cock reached the end of Ace’s throat, so soft and comforting. All Sabo could do to help was tuck Ace’s hair behind his ear, and the older man would do his magic. Must’ve been from all the experience, Sabo assumed. But he didn’t like the thought of his lover being with other people before him.

Sometimes Sabo regretted not being born much earlier. That way he could go and meet Ace much earlier. Covet him, seduce him to become his before Ace’s heart got broken over and over again. Handsome, lovely, and charming Ace–of course, the old man was still the same way as he did during his younger times. The only differences were the growing wrinkles at the end of his eyes, deeper smile lines, and the longer hair, but Sabo never minded them. He loves Ace just the way he is.

With several more rough sucks and tender licks on his cock, Sabo came inside Ace’s mouth with a loud grunt. He panted breathlessly, rough hands caressing the older man’s face, his thumb wiping the spit and cum that rolled out of the corners of his lips. His watery eyes looked beautiful in Sabo’s eyes, tempting him to give him everything he wanted.

The blonde pulled Ace into a kiss, tasting himself in the other’s mouth, sweetened by the taste of the older man. Sabo loves kissing him. Despite his so-called experience, his age, and the wisdom Ace was supposed to hold, he would always get a little shy when Sabo kissed him like this. He sucked on the older man’s lower lip, his languid tongue entering his mouth to roam and dance against Ace’s, while his hand pushed the man down to lay on the bed once more.

The older man whined and closed his eyes, feeling his tongue get kneaded and embraced by Sabo. He looped his hands around the younger man’s neck, feeling thick muscles under the shirt the blonde was wearing. Ace clung against him, trying to keep up with the kiss, only to be met with a smirk against his own lips.

“Relax,” Sabo whispered softly, pulling away slightly before giving Ace a light kiss on the lips. “Let me do all the work, okay? You’re always so tense. You don’t have to do anything, let me pamper you.”

“It’s hard… getting used to this,” Ace looked away, a little embarrassed that he just couldn’t let go of old habits. His body had been conditioned to take on responsibility for so long, to please, to provide, that he didn’t know how to receive things well.

“Lay down, love,” Sabo told him, slipping a hand behind Ace’s back to coax him to lay on the bed. “I want to make you feel good. You don’t have to do anything when I’m here,” he leaned down, flicking his tongue on a hardened bud, nursing on it.

“You’re not a father when you’re with me. Just Ace– my Ace. In fact, it’d be better if you were just my husband. A wife, even,” Sabo babbled as he sucked and licked Ace’s soft breasts. “Yeah, you’re definitely meant to be a mother. What’s the point of having breasts this big if you’re not going to use it, baby?” the blonde teased, biting and pulling the nip lightly. “So sensitive.”

Ace hissed at that, arching his back to let Sabo do more. The blonde smiled at that, taking his whole nipple into his mouth to suck, while his other hand played with the other. Wet sounds filled the air, and Ace couldn’t care less because he was feeling good. There’s a ticklish feeling in the pit of his stomach, making his hands push Sabo’s head against his chest to suck harder, to bite and twist and nibble on him until he’s writhing from pleasure just from his breasts.

He heard a click by the nightstand, somehow Sabo had managed to free his hand from under his body and grabbed the lube, wetting his hand so clumsily that the blue thick liquid was dripping everywhere. But it didn’t matter, Ace didn’t have the capacity to nag at the younger man when he’s beginning to travel downwards to play with his hole. The cold sensation made Ace hiss as Sabo circled his rim with his finger.

“Haa-ah,” he moaned, feeling the blonde’s thick finger enter him easily. He instinctively widened his legs, letting Sabo enter deeper.

“You feel so soft and tender,” Sabo grinned, entering another finger. Scissoring his fingers inside Ace, he slowly threaded closer to Ace’s sensitive spots, inducing a whine from the older man. He began to pump his fingers, pushing and rubbing his prostate each time. “Did you play with yourself before I arrived?”

“I– wann, wanted to be ready, ngh– for you,” Ace slurred, feeling his hips move against Sabo’s thrusts. He couldn’t focus his eyes on the blonde, but he knew Sabo looked proud.

“So eager for me. You missed me that much, huh?” Sabo cooed, thrusting harder as he watched Ace throw his head back on the pillow. Ace was so incredibly wet, clear pre-cum dripped off his cock like a faucet on his own stomach, pooling between his soft abs. His hands scrambled for the sheets, soft pants escaping out of his lips.

“S-Sabo, ‘mm- m, gonna come if- if you keep this up,” he whined, trying his best to hold it in. It only made Sabo thrust harder inside him with pinpoint precision, making Ace roll his eyes back into his head with a loud moan.

“Is that so?” the younger man smirked, enjoying the view. “So what is it that you want me to do?”

“Hnggh– ooh,” Ace let out a moan, body rocking from the sheer force of Sabo’s thrusts and the need to meet them with his own body. “Shh– Sab’o, puh, please, please, hh–”

The blonde clicked his tongue. “Come on, talk to me clearly, baby. You’re mature enough to tell me what you want, right?”

“Fuh–” Ace threw his head back, trying to contain the building pleasure in his body. Drool was escaping his mouth as he shuddered, his knuckles turning white from the vice grip he had on the sheets. “Fuck, fuck me, fu, fu–uck me, please–”

Sabo took out his fingers, making Ace sigh at the loss. His thighs were shaking like a maiden who just popped her cherry. How cute. “See, how hard was that?” he chuckled, taking off all of his clothes to give Ace time to calm down.

“I’m too old to, to be saying these things, Sabo,” Ace slurred, chest heaving as he relaxed once more into the bed.

“Nonsense,” Sabo scoffed, folding his clothes perfectly before dropping them off the bed onto the floor. “I love seeing you beg for me. Having someone as mature as you to need me… feels exciting.”

He grabbed Ace’s jellied legs and spread them open, smiling when he managed to fold the older man into a different position so easily. Even with his old age, Ace was still so flexible, so pliant with whatever Sabo wanted him to do. “With our ages, I should call you daddy, shouldn’t I?” he smirked, leaning down to press a kiss. “Wouldn’t it be funny if I called you that?”

Ace pouted at that, looking away. Sabo just chuckled. “Oh, don’t get cranky on me. I’ll keep calling you baby, love. Someone who acts like you definitely can’t be called a daddy. You’re too sweet for that,” he said, lining his cock against the older man’s hole.

Sabo’s wet cock pressed against the other’s rim, slowly breaching the tight heat easily. It sucked him in almost immediately, his walls gripping him so hard that Sabo hissed every time he tried to enter deeper. Ace cried, slowly opening up even further for Sabo, his thighs shaking from the intensity. Once Sabo bottomed out, he sighed, rolling his hips once, twice, just to watch Ace’s reaction to having him inside him. Cute.

“It’d be much better if you called me daddy instead, don’t you think?” he asked, rolling his hips again just for the fun of it. Ace gripped the sheets under him and let out a soft moan, his prostate being nudged again and again with every roll. “Hm, why don’t you try calling it out for me?”

“Mmh– ah–” Ace squirmed, refusing to meet Sabo’s eyes. “O-ohh!”

The blonde pulled out and slammed back in, knocking the air out of the older man. “Come on, why are you so shy? Try it once, then you can decide if you wanna continue or not.”

“Yo–ou, talk too much, daddy,” Ace said while gritting his teeth, his eyes narrowed into a glare.

Sabo laughed at that, slowly continuing his thrusts into Ace. “And you protest about everything too much, baby,” he chuckled, picking up the pace a little. “Does this feel good? Want me to go even faster?”

Ace nodded helplessly. “A-and harde-r, I can, can take it– fu–”

“Say it,” Sabo slowed down, his thrusts turning shallow, actively torturing the older man.

“I can’t believe you,” Ace huffed.

“Come on, I know you’ll like it.”

“You are such– mgh, a brat.”

“Consequences of dating someone younger,” Sabo grinned with all of his teeth. He was slowing down so much that Ace was rolling his hips, trying to chase after his cock with a small frustrated frown between his eyebrows. “Say it, baby. Say it for me,” he urged him, hand reaching down to brush the slit on the head of Ace’s cock, making the older man gasp in pleasure.

“Hngg– D, daddy, please, please, harder, I- I need you to go harder on me–ee,” Ace threw his head back.

Hearing that, Sabo quickly thrusted harder, deeper, hitting all of his sensitive spots as he rammed his prostate. Ace gasped and moaned into a stutter, eyes fluttering close as the younger man vigorously fucked him through.

He couldn’t do anything else. His hands felt limp against the sheets, his head lolling to the side as Sabo kept ramming into him like there’s no tomorrow. There’s heat pooling in the bottom of his stomach, fluttering as his muscles spasmed and trembled from the pleasure surging inside him. Sabo’s cock is perfect for him, always giving him what he wanted and needed, molding his tight passage into his form. The younger man’s hands were also perfect, holding him down by the hip, his grip definitely leaving bruises the next day that Ace could marvel and be reminded of what happened the other night. 

Sabo–he’s so perfect for Ace. He’s the only person who could understand him throughout his 40 years of living. He’s the only person who could reciprocate the love Ace gave him, giving him attention and affection so abundant that sometimes it overwhelms him. Despite his younger age, Sabo seemed to know him for longer than he ever lived. He didn’t have to hide his true self from him. If he wanted to moan harder, to rip the sheets beneath him and act like a slut for Sabo, the blonde won’t judge him. And Sabo’s big. Enough to give Ace a little pain with every breach Sabo gives him, which felt satisfying rather than uncomfortable.

But what takes the cake is Sabo’s stamina. He’s young, so he’s relentless when handling Ace. Truthfully, he didn’t know whether it’s a good thing or not.

Sabo easily flipped Ace over, shoving his face down on the bed. Ace could feel Sabo thrust deeper inside him, making the older man’s eyes roll to the back of his head. He couldn’t think straight anymore, the younger man ramming into his prostate with such ferocity. The bed skidded on the floor, the sound of wet skin slapping on each other felt sinful and it's the only thing Ace could register from his surroundings.

“Fu-ck, you feel, so, so fucking good, baby.” Sabo moaned, his grip on Ace’s waist tightening even further that it hurts. “Your old boyfriend didn’t pamper you like this back then, didn’t he? Not even your fuckass wife. Poor baby. I’ll give you what you want,” he groaned, sending shivers throughout Ace’s body. “I’ll make sure to take good care of you. You always love this position, always tightening so hard around me, so perfect for me baby. Does it feel that good for you?”

“Y-yeeesss–” Ace slurred, mind turning into mush. His hole is definitely destroyed by the time this finishes. He won’t be able to sit or even stand tomorrow morning.

“No, that’s not what we agreed on.” Sabo leans on Ace’s back, covering him entirely. He raised Ace’s hips, just enough to grab Ace’s abandoned cock and started stroking it, making the older man under him shake and falter.

Ace’s knees buckled, letting Sabo’s hands be the only one that’s keeping him steady. “Y-fuck, yess, daddy, daddy, daddy, daddy, daddy, daddy–”

“Do you like me playing with your pretty cock?”

“Haa–nghhhh–” Ace keened, nodding vigorously against the crumpled sheets. His hair covered his face, tears, sweat, and drool dripping down his face and making strands of hair stuck to his face.

“I can’t believe your pretty dick managed to conceive a child. This thing shouldn’t be used, no? You're meant to be taken from the ass,” Sabo whispered roughly, biting on his ears, hands kept moving to jerk him off. “I wonder how you felt during the night of your wedding. But aren’t you glad you did it? your son went ahead and made friends with me, someone who could finally make you cry from pleasure.”

Ace sobbed, “D-ah–ddy, sl–slow doh–wn,” Can’t, can’d tt–hinkk–”

“You don’t have to,” Sabo kissed his shoulder blade. “I’ll take care of you,” he said, moving his other hand from Ace’s hips to play with his nipple, pulling and twisting them between his fingers.

Ace raised his hips and grinded his chest against Sabo’s hands, chasing the sensation. “Haa– mmgh, nn–”

“No matter how much I’ve played with them everyday, you’re still not producing any milk. Should i fuck you everyday so I can get you pregnant and get you to lactate?”

“Yes, yes, yes, yes—“ Ace incoherently sobbed, his hand gripping on Sabo’s wrist weakly.

Sabo cooed at that. “Baby, you do know you can’t get pregnant,” he said with pity, while the crazed man under him whined and forgot about any logic and the world around him. 

Ace’s hips falter, his whole body trying to crash down despite Sabo’s hands on him to keep him steady. He’s getting overwhelmed, his body running hotter, stomach churning while his hole spasms and tightens around Sabo into a vice grip. The familiar sensation was building inside him, fast, and all he could do was sob and let the pleasure overflow out of his body.

“Mm– comingggg, coming, ‘m comingcomingcomingcoming–”

Ace came, spilling into Sabo’s hand with a shudder. His thighs shook. His hole gripped Sabo with such vice that he pushed the younger man to come, groaning and shooting his load inside of Ace. The older man tried to catch his breath, his body falling onto the bed unceremoniously with Sabo’s cock still inside him.

Of course, since Sabo’s young, he gets back up quicker than Ace, pulling out his spent cock from the older man’s gaping hole with no issue. He helped Ace adjust his position, putting him on a stack of pillows and letting him lean on them like he’s in some sort of nest. The younger was faring much better than he did, who was still shaking and spasming now and then from the huge orgasm he just had.

But then as Ace relaxed into the nest of pillows, Sabo joined him, laying his head on Ace’s stomach, nuzzling against him from between Ace’s legs, his age showing from his actions.

The blonde always acted like this. After sex, Sabo reverts back into this cute kid that wants nothing but Ace’s attention. This time, it seemed that the kid needed reassurance, judging from the worry lines that’s forming in between his eyebrows.

“You just finished fucking me into oblivion, so why are you frowning?” Ace chuckled, caressing the younger man’s soft cheek.

“I’m a little insecure, that’s all,” he leaned against his hand.

“Tell me what you’re thinking.”

Sabo looked away, his cheeks turning a little more redder. “Promise you won’t laugh at me.”

“I won’t,” Ace grinned, his fingers carding through his blonde locks.

“I’m just… scared of what Luffy might think about this,” Sabo bit his lip. “I mean, I don’t care about my family. They can’t control me anymore. But Luffy–he’s your son. If he hates this–” he stopped, nuzzling into Ace’s stomach, “I don’t want to lose you,” he continued with a small voice.

“Hey,” Ace softly smiled, pulling the blonde to urge him to lay next to him. He kissed his lips tenderly, adoring how Sabo closed his eyes and chased after Ace’s lips. “You don’t have to worry about Luffy. He likes you too, you know? And don’t you think he’s going to prioritize his father’s happiness?”

“Mm,” Sabo hummed, letting the older man hug him.

“You’re the only one who’s able to make me feel complete, Sabo. You treat me how I want to be treated, and that’s what I love about you. You know how to make me happy.”

“I do?” the younger man perked up, blue eyes shining back brightly with confidence. Ace cooed at him. Sabo looked just like a puppy.

“You do,” Ace replied lovingly, kissing Sabo all over his face–his cheeks, his forehead, his nose, his eyes, and his lips–everything, just to convince the blonde how much he meant to him.

Then, Sabo got up and grabbed the older man’s arms. He pinned Ace down, caging him with his strong arms as he leered down on him with a smile. “I’m the best out of all your lovers, right? You love me more than all of them, right?”

Ace rolled his eyes. “Yes, Sabo. You’re the only one for me– mmh!”

Sabo kissed him, deep and slow. The blonde groaned animalistically against his lips, devouring Ace again, everything going back to square one. When he pulled away, blue irises were now dark and hooded, his lips gleaming with spit and want. 

“Wanna fuck you again,” Sabo whined desperately, looking like a pleading puppy who’s asking for food.

Ace sighed, spreading his thighs for Sabo to access him. He’s sure he’s going to end up unconscious by the time Sabo’s fulfilled.

Ah, youth. What was Ace going to do about Sabo?
