wc: 3.7k, nsfw, smut, lowercase intended!
law tried his best to educate his crew on the basics of medicine. he thought it was important for everyone to know the basics of how to treat wounds in case there was a situation where he wouldn’t be around to help. he would also set up some mock surgeries, and trained each member 1 on 1.
when it came to his session with you he found that you were the quickest to absorb the information. you watched carefully, and took notes accordingly. he could tell you took this serious unlike some of the other members. his expectations were low, but you singlehandedly changed that for him.
he decides to continue the next day teaching you more medical knowledge. law delved into many different emergency procedures, and explained in step-by-step detail how to deal with it. by the end of the day your hand was exhausted from all the notes you had to take.
bepo pokes his head in near the end of law’s expansive teaching session. the mink held up two popsicles, “i wanted to bring some snacks! i’m sure you’re working super hard y/n, so you deserve a break!”
the mink waddles over and hands them cool treat to you and the captain. law comments as well, “we can take a short break. it’s been a while since we start.”
you mumbled under your breath, “more like almost 12 hours…”
bepo gasped dramatically, “captain why would you torture our precious y/n like this!”
law dismissed bepo’s dramatic response, “it isnt dramatic. y/n learning this stuff could be the difference between life and death for one of you guys one day.”
bepo knew best than to argue back with law. he bid his farewell and left you two alone.
although it was meant to be a break law couldn’t help but keep up with the lessons in some way. as you tried to enjoy your sweet treat the tattooed man would point at different tools and wait for you to answer correctly. you responded in between your licks.
“you know i thought this was meant to be a break captain!”
“it is a break. we aren’t learning about how to deal with a bleeding lung. i’m just making sure you remember and were listening.”
you couldn’t help but think he was placing too much importance on this. still you kept your opinions to yourself. there’s no point in trying to voice them knowing that law has made his mind up.
law watched you suck the tip of the popsicle. his attentive nature had him notice the melted droplets start to roll down the popsicle, and inevitably drip off.
he spoke up before there was a chance for it to drip off, “lick it from the bottom.”
without knowing his reasoning to his suggestion you started to follow it. you started from the bottom and took one long lick to the top of the popsicle. you did this all around, and ended with sucking the tip of it. you looked back at your instructor waiting for him to approve like he always did when you listened to what he had to teach you.
instead law was starring mindlessly at your lips. the visual of your tongue gliding from the base to the top replayed on a loop in his mind. it was almost like he could feel it on his own dick. he tried to push the imagine away, but it had already cause the blood in his body to start to rush.
you tilted your head at the lack of response, “was that okay captain..?”
your voice broke law out of his trance, “uh..yeah that was fine..”
there was a long pause before he spoke again, “you should try eating it this other way. i think it’ll taste better this way..”
you waited for him to give you your next set of instructions. law walked over to stand next to you, and positioned your mouth right above the popsicle, “you should suck it.. but bob your head a little. it… helps with spreading the flavor across your whole mouth at once…”
law hoped the reasoning he made up on the spot didn’t sound stupid. he was relieved to see you obey his instructions like you had been for the whole day.
your lips encased the tip of the popsicle, and you slowly moved your head down then pulling it back up, but not enough for the popsicle to leave your mouth. you continued this motion for a while waiting for an approval signal.
after an extended amount of time passes you slow down to look up at law. you were immediately locking eye contact with the tattooed man who was starring at you the while time.
he spoke so lowly you almost missed it, “you’re such a fast learner y/n..”
you hummed, “i just follow whatever you think is best captain.”
you reached over to grab some napkins behind law. you were now leaning closer to him. his boner, which he was trying to ignore beforehand, had grown noticeably in size. it was big enough for you to accidentally hit your knee into.
law winces and grabs the edge of the table for support. the sudden movement sent a shock all over his body. you, who didn’t know law’s boner was a slow growing problem, thought you just caused this.
panic was laced through your voice, “oh no, i’m so sorry captain! i didn’t mean to do that! a-are you okay..?”
law was clearly not okay. he kept his head down to hide his scrunched up eyebrows. he but his lip aw his boner grew more against his restrictive pants, “fuck y/n.. what’s your damn problem…”
you kept apologizing not quite knowing what to do in such a situation. the notes you took all day couldn’t help right now, “wh-what do i do?? you’re in p-pain. you’ve been teaching me how to help someone in pain all day but i don’t know what to do in this kind of situation!”
law rubbed his temples and responded, “you do know…”
you thought law taught you this, so it must be written in your notes. you skim through them all to find something to help.
law pulled you close to him by the arm, and threw your book on the table, “you didn’t get the chance to write it down. it won’t be in there y/n.”
he starred at your lips with seductive eyes. the sensation had spread through his whole body, and quite frankly he didn’t care if he was pushing boundaries at that moment.
his hand made its way to your face to caress your cheek, and his thumb traced your bottom lip. he pulled it down slightly to expose your mouth as he stared at it, “i just taught you this, it should be fresh in your mind y/n-ya.”
your eyes widened as you realized what he was implying, “i-i don’t think i can do that capta-“
he cut you off immediately, “why can’t you? don’t you want to fix the problem you made especially if i’m giving you permission to do so?” secretly law knew the problem was existing beforehand, yet he didn’t care if a little white lie helped with getting your pretty lips around his cock faster.
you looked unsure, “i don’t know..”
law winced again. his pants becoming unbearably tight. he knew he would have to talk you through this, “you’re a fast learner. i know you’ll do great. now what do you do when your patient is in pain?”
“get them to a relaxed position, then treat the pained areas..”
law nods, “good girl. you’re already doing so good.”
you nod slowly, and instruct law to sit down in a chair. he manspreads to avoid unwanted friction against his pained area. he was now having noticeable shortness of breath trying to keep his pain under control.
you were still in a clear state of shock, and didn’t know what to do next. law takes a deep breath, “get on your knees y/n… you need to uncover the area you’ll be working on. i’m sure you remember this lesson…”
you nod fast and sit between his spread legs. your hands were shaking as you unbuttoned his pants. you were careful to not touch the boner unnecessarily. you were successfully able to pull law’s pants and boxers off with a bit of help from him. he kicked it a few feet away.
law’s dick sprang up once uncovered. you looked at it then at law who was still in noticeable pain, “wh-what should i do next..?”
law pushes your hair over your shoulder as he replies, “treat it like a popsicle. that’s gonna be the only way to fix it.”
you weren’t confident in your ability. you had never done anything like this.
law spoke again, “you’re my star student. if you get stuck i’ll just teach you how to keep going.”
you nod, feeling a bit more confident in your abilities. you recalled how law taught you to eat the sweet treat.
law pulled your head closer to his aching boner hoping it would get you to start. he was desperate for any relief.
you hold the base using only your fingertips, and pull the tip to touch your lips. it was hard against your soft lips. your fingertips could feel the veins that covered the aching cock. you pull the tip into your mouth, and let your lips engulf its circumferences. law grips the armrests of the chair as his head rolls back. he closes his eyes to focus on the new sensations you were giving him.
you started out sucking softly, then pulling the length back out your mouth and licking it up from the base. law let out shaky breaths with every lick that covered his hard dick.
law took your hand, and had you wrap it around his member, “do this to help with the process y/n.” law proceeded to move your hand up and down his member. once you got the hang of it he let you continue on your own without instructing your hand on doing it. he loved how he could tell you to do anything, and you would obey him so fast.
you went back to sucking his tip while including the stroking movement from your hand. the sucking continued to a bobbing movement which took in more of his length at once.
you were doing great a while, until law felt you start to slow down significantly. he opened his eyes to look at what you were doing.
he saw your thighs rubbing against each other as you tried your best to please him. he smirked at the sight in front of him, and pulled your head off his cock, “is everything okay y/n?” law’s eyes signaled to your thighs.
you nodded fast, “everything is o-okay! it’s just a bit of discomfort.. but it’s not important. you need to be treated as soon as possible.”
law hummed, “i think my symptoms were contagious then. you did your best with what your pretty could do. you should let me take care of this now. you’re going to be my patient now.”
law stood up and pulled you up from your seated position. you naturally kept rubbing your thighs together, and the sight of that turned law on even more. he picked you up with ease, and laid you across the table, “i’m gonna have to undress you to get to your wounded area y/n. will that okay?” law couldn’t keep his smirk off his face.
the growing sensation made you feel desperate to feel relief. you agreed without a second thought. law pulled your shirt off with ease leaving you in your bra. law traced his hand up your stomach, and let his thumb play with the bottom of your bra, “are you feeling anything in your chest?”
you hummed to answer his question. he spoke up again, “are you able to show me which part specifically?”
“i-i guess..” you unclipped your bra and pulled it off. being exposed in front of your captain had you blush uncontrollably, but he wasn’t your captain right now. he was your doctor, and he would help you feel better right now.
you shyly pointed at your nipple, “i feel it here…”
law hums and carefully takes your breasts into his hand. they sat well in his palms as he pinched your nipples gently. he observed how your face turned into a more desperate expression. you started to but your bottom lip as he rolled his fingers over the sensitive buds.
“i’m gonna need your help with this next part baby.”
you were attentive with the new name he called you. he knew you were willing to do anything he would tell you next.
“i need to you to put some of your saliva on my tongue to help me out.”
“my saliva..? how would i get it on your tongue?”
law smirked, “push it onto my tongue using your tongue.”
you were unsure of the visual he was trying to paint out, but nonetheless you didn’t question him any longer. you saw him stick his tongue out waiting for you. you inched closer to him and gently pressed your tongue against his. law needed more than what you were giving him. he pushed his head slightly closer to connect your lips. it was a wet attempt of a kiss as he tries to steal all the liquid in your mouth. once satisfied he pulled away and went straight to transporting that to your nipples.
law knew he could’ve done this without your help, but he just wanted a reason to feel your lips against his, and your tongue dancing alongside with his.
he went back to pleasing your nipples. you let out quite whimpers and moans with every suck and squeeze the man did.
law spent enough time ignoring his own problem, so he pushed open your legs to start to grind his boner against your cloth heat. this action made you create louder noises than before.
once satisfied law pulls away from your chest. he looked at his artwork, and admired how puffy he left your gorgeous nipples. law took your hand and made you grab your own boobs, “start playing with these while i take care of the bigger problem. you think you could do that for me baby?”
you hum and try to replicate what law was doing. you were a fast learner after all, so you knew to focus your attention to your nipples.
law focused his attention to in between your thighs, his crotch could feel your juices soak through your pants. he needed to uncover you now.
so he wasted no time with doing so. in an instant he had your pants next to his on the floor, and had your panties tucked away in a drawer next to the table you were on. he knew his future self would be thanking him for such a priceless gift.
the cool air sent shivers up your spine. you closed your legs shut, “its too cold!”
law hums as he slowly tries to reopen them, “you’ll feel uncomfortable now, but i promise you wont notice it in a bit. just be cooperative with me for now y/n.”
once re-exposed, law takes his aching length, and pressed it against your wet core.
he let your juices cover his cock, and slowly rubbed it through your folds. he observed you with every movement, not wanting you to feel overwhelmed.
“this is gonna feel a bit different, okay?” you could only conjure up a hum as a response.
law focused his hard tip at the top of your pussy, and rubbed his tip against your clit. he watched your body react as you let out soft moans. he could see goosebumps form on your arms as he continued the motion. he rubbed your clit in circular motions with his tip, until stopping with your clit sitting perfectly next to his opening on his tip.
he stopped his movement to talk to you again, “i’m about to do the main part of the operation. its going to hurt at the beginning, but it will make you feel great afterwards. you’ll feel so much relief after we’re done. are you ready?”
you were still unsure. law reached over tor cup your cheek reassuringly, “you’re gonna be okay. you trust me don’t you?”
“i do trust you…”
the smirk returning back to his face “then let me finish my job, i need to make sure my patient feels better by the end of this.”
you nod, but hold his wrist so he doesn’t remove his hand from you. you shyly pull it from your cheek to hold hands with. law lets you lace your fingers with his. he figured you’d need something to squeeze.
law pulled his tip to your slit, and pushed it in slowly. he saw you tense, scrunch your brows, whimper, and squeeze his hand. he knew it must’ve been a new feeling for you, so he had to treat you extra carefully.
he was halfway in before he pulled back out. he continued this half in half out motion to help you get used to this new feeling. he didn’t want to overwhelm you.
you were doing your best to keep your voice low. when you felt a loud moan wanting to come out you immediately moaned into the tattoo hand to muffle the sound. the sight of you using his hand in such a desperate situation drove law crazy, and he unknowingly pushed in all the way. you gasped loudly at the new sensation. you were immediately being stretched out by his size.
law cursed under his breath, “shit, i didn’t mean to do that.”
your voice trembled, “i-its okay law”
he nodded and continued at a steady pace. law rocked his hips at a controlled pace. your warmth was inviting his cock to keep thrusting in. the longer it drew out the harder he would start to thrust.
it started out gradual. the force was enough to see your breasts jump sightly. it then escalated to your whole body moving force the force. finally his thrusts turn hard enough to start knocking things off the table.
your moans would fill up the room. it was dancing in melody with the sound of law’s impactful thrusts. you were unable to control your body and the sounds it was making. your mind was blank, and all you could think about was feeling good because of his dick in you fucking you mindless. you wanted him to go deeper and deeper. you wanted him to fuck you into oblivion.
on the other hand law felt like a horny animal with the rhythm of his movements. every thrust pushed you away from him, so he had to keep a tight grip on your waist to pull you back close to him. your whimpers grew louder and more high pitched. it was signaling that you were close. law felt his hand you had near your face get wet. he looked up to see your teary eyes and seductive expression looking back at him.
he could tell that you were lost in the moment, and would take whatever he would give you. seeing you in this state made him never let you out of his sight ever again. he wanted to mark you up to show the world that you already belonged to someone. his mind filled with animalistic thoughts, and it reflected on his heightened pace.
he leaned down to your neck and started to mark you up. he sucked and left bite marks all over your neck. the only thought on his mind was how you were his, and his only. he wanted to make sure you would never get away from him.
you abandoned the hand you were holding onto and relocated your hands to law’s hair. you tugged on his hair trying to help ground yourself, but it felt impossible. you kept climbing high and higher towards your climax.
law’s out of breath voice was heard in between the thrusts, “are you feeling good baby? you feel so fucking great… i need to fuck you like this all the fucking time.”
you mindless nod in between your moans. it felt impossible to make coherent sentences at that point you could only get a few words out, “it f-feels so good law! ahh!” tears tricked down your face as you felt a knot undo in your stomach, and your come orgasm crashing down on your body.
you produced sounds you didn’t know where capable of being made. hearing your seductive vocals pushed law into reaching his own orgasm.
he shot his cum deep into you. you felt the warmth fill you up even more than you were. law’s pace slowed down significantly, but he couldn’t help stopping then. he fucked his cum deep into you. his thrusts were much more sloppy than it was before. he just wanted to mark you as his in as many ways as he could. he didn’t even bother wondering if you wanted to be his to begin with.
once finished he finally pulled out. you both stared at each other as you regained your breaths. you we’re completely fucked out, and law couldn’t stop admiring you in such a state. he leaned closer to you and kissed you passionately. it was a very lazy passionate kiss which you tried to return in your exhausted state.
law pulled away and looked st you with hooded eyes, “i need you to be mines only..”
“wh-what captain..?”
law groans, “stop with that captain bullshit.. just say you’ll be mines” desperation laced his voice. he wasn’t trying to make it sound like that, but it was hard to control it while being so exhausted.
you just mindlessly nod as a response.
once law is able to regain some of his regular breathing he uses the last of his energy to shambles you both to his bed in his private room.
he pulled you close to him, afraid you would run away from him at any given second. you on the other hand didn’t have the energy to even move positions. you let law hold you close without complaints, and felt him steal another lazy kiss from you. you slowly drift into a deep sleep with law following right behind you.
