Chapter Text

Rosinante is not close with Dr Trafalgar, not personally so, he just happened to be the officer first on the scene when they had crashed. But the whole family (Doctor, Daughter and Heavily Pregnant Wife) had all made it out okay, and if someone wanted to put a little hero worship into him for just doing his job he was beyond trying to stop them by now. 

Being named Godfather of their newborn son however, is quite a surprise. 

It'd be an honour if it didn't also technically come with some, minute, responsibility as well. And while he doesn't expect the baby to suddenly become an orphan, he also does not want to end up hooked on the line for a child he  has no interest in. 

So on one of his days off he buys a bouqet of flowers, and goes to the hospital to both congratulate and politely decline. (He doesn't want to sound ungrateful, of course, but couldn't they have just given him a middle name and called that it?) 

Once he's there, and before he can explain, the flowers are gladly taken from him and somehow almost immediately replaced by a tightly swaddled bundle that is apparently Trafalgar Law. 

He doesn't hear a word anyone else says once Law is in his arms (his hands really, this baby is so tiny-), world suddenly tunnelled down to just the two of him. Law squirms, and faintly Rosi is terrified he'll scream or fuss and be taken away from him, but instead it's to unravel enough for an arm to make free from his cocoon of blankets. 

Impossibly small fingers reach out and wrap around his, showcasing the vast size difference between the two of them. His face lights up as he lets out a happy gurgle at his accomplishment. 

Rosinante tells the happy parents that Law is already the cutest godson in the world, and they beam back at him. 

–

He doesn't even make it out of the hospital, instead heading to one of the single person washrooms. The door hasn't even fulled slammed shut behind Rosi before his hands fumble to undo his belt, freeing a throbbing hard erection beneath his trousers. The other grabs for his phone, immediately swiping through to the texts of the photos Law's father had sent him of the newborn. 

He slams his back against the door as he hurriedly begins to fist his cock, spurts of precum already oozing out the top. He tries to ignore the thought that one of those single globs could probably coat all of Law's little hands, let alone his face- 

Rosinante would blame a sexual draught and pent up lust; overfull balls ready to burst now that he had a sexual outlet. With his mind full of endless terrible thoughts and possibilities, he cums thick cum across the bathroom in the maternity ward. A wayward splatter makes it onto his phone screen, near perfectly landing on Law's open mouth in the picture. 

It's almost like a sign , he rationalizes to himself as he leans against the door and collects his breath and mind in a post orgasmic haze. 

Not that he needed much logic to further push him, Rosinante was pretty sure he was already in love .

–

The first time is after a few months, sadly. Like good parents his Mom and Dad stay with the newborn as much as possible, and when he can finally have more than a few moments alone with him unguarded comes when Lami begs to see some new movie. Even child appropriate, it definitely isn't a place for Law quite yet. 

So Rosinante gets an evening of babysitting that, despite Dr Trafalgar profusely apologizing over, he is ecstatic for. 

Law is asleep, down for a nap though Mrs Trafalgar said knowing him he could be down for the night too before they had left. Tucked up in a Sora Warrior of the Sea onesie, and splayed out across an army of plushies in his crib. 

It's almost too easy, all it takes is for Rosinante to slide the gate down on one side and the mattress is already nearly at cock level. 

He doesn't have much of a load to offer, and in his mind Rosi isn't sure if he had had more planning time if he'd made an effort to save up his cum or to make his balls as empty as possible to hide the evidence. 

Rosinante presses the head of his cock against Law's pudgy little face, dragging from cheek to cheek and leaving a smear of cum right across his mouth. With any less self control he would be instantly shoving his whole cock into that barely open gap, but he doesn't want to lose everything on their first time together so he holds back. 

(But he doesn't hold back from taking out his phone and snapping a few pictures of Law's sleeping cummy face, some of his cock just resting on his face and nearly reaching across his whole body -)

It's disappointing almost, to cum so fast when they have several hours together, but the way he perfectly aims so several thick globs of cum land across Law's face and body makes up for it quite well. He strokes his cock a few times after, squeezing out the last drops of cum he has to offer right over Law's barely parted lips. 

Law fusses gently in his sleep, sticky goo on his face causing some kind of discomfort, but before Rosinante can reach to wipe it off Law has reached one of his own hands up. Rather than wiping it off though he sleepily seems to just smear more across his cheek before his hand goes to his mouth, shoving the last drops of cum in while also suckling on his gooey fingers. 

If Rosi had more in him, he's sure the sight of Law already being cum hungry while still asleep would've pulled another orgasm out of him.

Instead he takes out his phone and carefully records as he uses his own fingers to drag and scoop through the mess of cum on Law's little face, pushing it to his mouth and watching as he seems to happily suckle it all down. 

On the last bit he dips his own finger in between the baby's lips, one wider than the three of his own small hand Law had been sucking on, and feels firsthand how he licks them nearly perfectly clean. 

Rosinante takes the upmost care to clean up afterwards with wet wipes, to leave no sign that he'd even been in Law's room beyond rearranging some plushes and tucking him back in. 

When the Trafalgars come back home, Law has stayed sleeping all evening, and he laments to them that they didn't get any time to play together. 

Dr Trafalgar smiles, has no reason to question that play time could mean anything else, and happily tells Rosi that he'll be their go-to babysitter whenever they need on then so they get more time together. 

–

Bath time has easily, and obviously, become one of Rosinante's favourite tasks. He's thankful for doctors hours, now that both maternity and paternity leave are over, that often leave him in charge of Law for nights while Lami has a sleepover at a friend'. It means he's in charge of Law's bedtime routine, which always includes a bath. 

Old enough to hold up his head and graduated from a basin in the sink, but still small enough that Rosi would be too worried to actually sit in their with him, he kneels on the outside of the barely filled tubbed and carefully scrubs Law clean. 

He barely fusses when Rosinante tips his head back or manoeuvres him around to rinse him off, happily cooing and splashing in the water while he's cared for. 

Law only seems to react when Rosinante's bare fingers dip below the water and parts his cheeks to press against his tiny hole.  Even then he pauses before just starting to giggle madly- apparently ticklish. 

When Rosi pulls him out and dries him off, Law is too young to notice that the towel drops often whenever he goes to dry around his tiny bum or cocklet, to realize that the exploring fingers shouldn't be there. That the funny tickling feeling should be bad, not good. 

Tucked close to Rosinante's chest, already on the edge of drowsing off, all little Law can know is that this person is safe , and he trusts them. 

–

"The cold medicine will make him drowsy and out of it," Mrs Trafalgar had warned him. "So don't worry if he's not as playful or babbly as usual. It'll probably be a night where he'll just want to sit with you while you watch TV or whatever else." 

Rosi had listened as best he could, while also cooing over the adorably still sick toddler. Snuggled up on the couch currently in a pile of blankets where he had dozed off earlier, Law leans towards Rosinante's hand as he pets through his hair. 

He waves off the parents from his position next to Law, and then the night is just theirs. 

Law has grown up quickly, baby fat still clinging to him, but already at the stage of sounds becoming words enough that Ma and Da are constantly in his babblings. Rosinante knows words and proper names will follow soon, and he can't be sure what Law will start saying or remembering now. 

Their times together are going to have to come to an end soon, at least until Law is old enough to keep a secret. Tonight, with him already pliable and dozey from his cold and the medicine, has presented Rosinante with the perfect chance to say goodbye . 

Swaddling up the boy as best he can in his nest of blankets, Rosi decides the best place would be his changing table; clear open space, conveniently at crotch height and already having a nest of useful supplies. 

Setting the Law-burrito atop where he would usually be stripped down anyways, Rosinante pulls out a phone (by now a lovely burner dedicated just to his playdates with Law) and perches it up where it has a decent view of Law and is ready to record. 

Carefully he unwraps the blankets from Law, the tot so out of it he barely fusses or moves around until he's laying naked on his open diaper. 

He wraps his his hand around chubbing up cock a few times, collecting the precum across his fingers while just watching Law lie their naked, before an idea smarks. 

Law's tiny cocklet still too small to do really anything, Rosinante pinches it gently between his fingers and gives the baby the best approximation of a handjob that he can with their size difference. Though he can't get hard yet, the blonde watches in glee as Law seemingly tries to push his hips up towards to touch during it. 

He uses his other hand to carefully grab a dollop of vaseline before pressing a finger against Law's bum. Impossibly tight, but much looser than he ought to be from their other sessions, Rosinante wishes that he had had the foresight to truly prepare Law for tonight. 

When he starts to squirm and fuss more than usual- as Rosi forces in finger two, pressing them not even up the second knuckle before he's at his limit- he doesn't really have a plan to calm him down. His only idea is the same he would use on a normal lover complaining about his size- he leans down and presses his mouth over Law's to silence him. 

Baby now held firmly in place at two ends, the fingers up his ass and Rosi's tongue suddenly snaking into his surprised mouth, it feels nearly a breeze to work him up to a third finger now. 

It's only when Law starts to gag because Rosinante has shoved his tongue too far down the child's throat that he realizes and pulls away, chest heaving. Law's little face is a mess of drool and tears, which would not be an odd sight if not for the smear of obvious red lipstick across his mouth. 

The view almost makes Rosinante want to cum right there, never quite used to how lewd Law seemed to look for a baby. With that he quickly pulls his fingers out of Law's hole- He wouldn't be ready for a full grown cock, not tonight and not for years probably.  

But, just the tip? That was doable. 

He forgoes a condom, but does make sure to lube up his cock as thoroughly as possible. Pressing the head against Law's hole, still wider than even three of thick fingers, Rosinante also leans down to put their faces by eachother. Starring into Law's drowsy and doped up eyes, he can almost convince himself they're full of as much lust and love as his own. 

Rosinante leans down and seals their lips together again, just as he nudges forward and pushes the head of his cock inside of Law. 

The baby tries to let out a little whimper or scream of pain, but it's muffled into Rosi's mouth. Who only uses it as opportunity to shove his tongue back past Law's lips, this time at least more careful to keep it withdrawn enough that he knows Law won't choke. 

In all this though Law still squirms , which is the perfect amount of movement and friction for Rosinante. Unable to risk even the slightest of thrust or losing himself to the pleasure and possible hurting him, the movement of a fussy baby does just enough to push him over the edge he'd already been near. 

Rosinante lets loose at least two spurt loads of cum before he thinks to pull out, ending with the rest of his ball load decorating Law's ass and cocklet while dripping down into his diaper. Even just from that, he worries that his little stomach looks slightly more bulging than it had been before. 

With his mouth now free, but the source of his discomfort also suddenly gone, Law just gets out a ragged huff and a whimper. Looking even more tired than before, he drags his hand up unknowingly through the field of cum, before popping a gooey thumb into his mouth as he slowly drifts to sleep. 

Rosinante bites his lip, ignoring the throbbing feelings in his balls that suggests trying for a second round. After he stops his recording, and does a mini photoshoot to captures all the angles of Law with cum dripping from him, Rosinante finally returns to the familiar task of cleaning up the cummy baby.

While the usual wiping and outfit change works for most of the mess he's made, he can only hope that whatever cum he's left inside Law doesn't end up just leaking back out into his clean diaper as obvious as it had looked all over him. 

Picking up the reswaddled baby, Rosi carries him on his hip back out to the living room and holds him close as he puts on some child-friendly movie that he hopes Law will like whenever he wakes up. 

He looks down at his precious godson and presses a chaste kiss to his cheek. Rosinante loved Law, so very very much. 

Chapter Text

Cora uses scarves rather than rope- hopeful if they leave any marks he could pass it off as being tangled up in his blanket in the night, rather than the obvious sign of ropeburn. 

Its a different purpose really too, than rope. Where Rosinante might usually take the time and effort to make intricate patterns of knots, here every knot has its purpose in holding his partner down. 

Particularly, holding down baby Law so he didn't squirm too much while Cora's cock was dangerously close to his fuckable pussy. 

At home it'd be easier, position nearly perfect in Law's crib. But while accompanying the Trafalgar's on vacation and offering his freetime to babysitting meant plenty of alone time together, he rarely had the time security to do anything fun. 

Now, Law held firmly down against the changing table in the single restroom on a nearly abandoned floor of the hotel, patience has made him all the hungrier for it. 

Still too obviously young and tiny for proper fucking, lest Cora's already oversized cock rip his baby womb apart. 

So Rosi slides a lube covered hand across Law's bare thighs, messily smearing them with it and making sure to dip his finger between the tot's pussy lips while doing so. 

Properly lubed up, he takes the end of the last scarf and uses it to keep Law's feet together- pushing his plump little babyfat thighs tightly together. 

The sight was nearly as good as Law's plumping moist pussy, but the benefit was he could show his cock into this one. 

Cora shoves his fat cockhead between the tight thighs, holding for a second to ensure he was lined up to not actually hurt Law, before pulling back and starting to hammer the baby's thighs like he would a cheap whore. 

Each violent thrust making his balls slap against Law's tiny ass, filling the small room with the hollow echoing of skin on skin between Cora's heaving breathing. His cock so long the head brushed up against Law's confused little face, leaving streaks of precum that gooily stretched between them.

Rosi is content to continue fucking like that, using Law's thighs like a cocksleeve until he cums, but Law is apparently not. Bored by this game, he reaches his hand as far as the scarf wrapped around his wrist allows him- not far enough to get free but apparently close enough to wrap tiny baby fingers around Cora's throbbing cock. 

Near instantly he cums, directly aimed at Law's face. 

Before he has time to readjust, several thick, fertile loads come out and cover the baby's face. Even then Cora's efforts to pull away just manage to leave a breadcrumb trail of cum across Law's tiny body, until he finally gets his cock away- after he's emptied the last of his balls. 

After a second, when he's calmed down and had time to tuck away his dick, Rosinante looks down at his work. Law, squirming as best he can still tied up, a gooey mess of cum, only starting to look fussy because he's bored. 

Licking his lips, he grabs a fistful of toilet paper and begins cleaning the both of them up.
