Rocinante was flustered, the first few times she woke up to find Law curled up against her side, fast asleep. Not because he was there, but because he was always, without fail, hard as a rock, his stiff, still-developing prick pressing into her side or thigh or back.
Eventually, she got used to it. Law was thirteen, it was completely normal for him to be getting erections, she reasoned to herself, there was no need to be flustered over something completely natural.
Law, for his part, never said anything about it, didn’t even seem phased, just did his business (not in front of her, thank god) and moved on.
Eventually, she got the courage to ask about it. They were going to be traveling together for an indefinite period of time and it hadn’t even been two months yet. She needed to discuss it with him before it was too late to say something.
“Shouldn’t you be more embarrassed waking up like that next to a grown woman?” She asked one morning, pointing at his half-hard erection without actually looking at it.
“Am I... supposed to be embarrassed?” Law asked, his face uncertain, and Rocinante almost panicked. She just wanted to make sure Law understood boundaries, she didn’t want to make him body shy!
“No, no!” Rocinante denied, “no one should be embarrassed about completely natural bodily functions. But... well anyone would be embarrassed to wake up with it pressed against someone else’s body. I was pretty flustered the first few times it happened.”
“Oh,” Law looked contemplative, “does this have to do with uhm... consent?” He asked.
“Well... no not really,” Rocinante blinked a few times, “you’re not doing it on purpose, so it’s not like you’re doing it non-consensually, it just sort of happened. Who taught you about consent?”
“Doffy did,” Law replied, “she taught me that no one was entitled to my body and that if I didn’t want someone touching me, I should say no. And if they kept going after that I should cut their hands off.”
“Huh. Guess she’s not as bad with kids as I thought,” Rocinante said.
“She let me sleep in bed with her a lot,” Law said, “and took baths with me too sometimes.”
“Do you... think of her as your mother?” Rocinante asked in trepidation.
“No...,” Law furrowed his eyebrows in thought, then, more firmly, he said, “no. I don’t love Doffy the way I loved my mom when she was still alive. It’s different.”
“I see.” Inside, Rocinante was relieved that she hadn’t taken an already traumatized kid away from his second mother. That would have made their search for a cure so much harder than it needed to be.
That night, she woke up in the middle of the night by the sound of Law whimpering in his sleep. At first, she was concerned. Was he in pain? Was he having a nightmare?
She turned over to check on him, but her shifting just made Law burrow deeper into her warmth, his breath hot over her breasts and - much to her embarrassment - his hard cock pressed against her stomach. She could feel the tip of it was wet through Law’s shorts, smearing pre-cum over her skin.
Oh. He was. He was having a wet dream.
She bit her lip, trying to ignore the way her nipples stiffened, her face flushing. Should she wake him? No, that would probably be worse.
She clenched her thighs, closing her eyes and trying to go back to sleep as though she wasn’t wet from having a thirteen-year-old pressed against her, wasn’t horny beyond belief at the sensation of his cock, hard and hot and right there. She was just. Pent up. Yeah. She hadn’t had any partner but her hands and a nice vibrator (an embarrassing but useful gag gift from her sister) in a while. That was it.
Feeling confident in her conclusion, she relaxed, finally feeling like she could sleep even with the arousal burning through her system.
Law let out a little sigh, and she smiled to herself, finding it more cute than erotic.
Then, he moaned, “Doffy.”
Her eyes snapped open. It was so quiet that for a moment, she thought she’d imagined it, but then Law said if again, whimpered her sister’s name.
Oh. Oh god was that what he meant when he said he ‘didn’t love Doffy the way he loved his mom,’???
Did he have a crush on Doflaminga???
That thought should have killed any arousal still buzzing through her veins. It did not. Instead, it was like it lit her on fire. What was Law imagining she wondered? Her sister was a beautiful woman, it was no wonder he’d dream about her. Hell, even Rocinante - no, not going down that path. Still, it stirred something in her.
She did not sleep for the rest of the night.
In fact, Rocinante got considerably less sleep on a regular basis after that. Law didn’t sneak into her bedroll (or bed if they were lucky enough to find an inn) every night, but somehow Rocinante got into the habit of waking up when he did. So now, more often than not, she suffered her way through long nights with Law pressed against her body, his form so small but so warm and tempting, usually with his stiff prick against her side or her thighs, sometimes whispering her sister’s name.
Really, it was inevitable that at some point he would find just the right angle to get off at in his sleep, she thought, a little hysterically, as she stared at the streak of white on her bared stomach, her sweater having ridden up in her sleepless state.
That didn’t really make her feel better about it.
It also didn’t make her feel better about what she did next.
She reached down with one shaking hand, running her fingers through the still warm load on her stomach. She bit her lip, contemplating bringing it to her mouth, but... the throbbing need between her thighs encouraged her to do something else with it.
His load was so small (he was so small) that she could scoop all of it up with just two fingers, which she slid down further. Much to her shame, she didn’t hesitate to slide her cum covered fingers into her soaking wet cunt, shoving her little boy’s load inside of herself.
She barely even had to do anything to get herself off, she was so pent up. Just a few rubs against her clit and then she was gritting her teeth to keep from moaning out loud as she shivered through an intense yet wholly unsatisfying orgasm.
And that became a routine. Whenever Law actually came during his wet dreams, Rocinante would furtively scoop it up and use it to finger herself to orgasm. (And if she shifted around more than usual to pull Law a bit closer to her, well, she was the only one who needed to know).
She was getting off more than she had in the previous two years and yet her sexual frustration seemed to have doubled.
And it didn’t help that she was painfully aware of how risky her actions could be. It’s not like Law had to be a certain age to get her pregnant. And that turned her on far more than it should have. The idea that he could get her pregnant and wouldn’t even know about it made her feel both ashamed and aroused beyond measure. The sick thrill of doing something so awful just made her that much more wet.
She knew she should stop, but quite frankly, her time with her sister had left her stripped of many of her morals she’d once thought so sound. And her time alone with Law... well, it was so much easier to commit a crime when there was no one around to see.
Maybe that was why when Law woke her one night, his hands fidgeting with the edge of his sleep shirt - which was actually one of her’s at one point - and an obvious erection, she gave in.
“Cora-san,” he whispered, embarrassed (and that was new - both the way he got flustered around her now and the way he called her ‘Cora-san’ so sweetly it made her heart skip a beat).
“Can- can you help?” He asked, not meeting her eyes, “it’s just - it won’t go away and it- it hurts a lot and-,“
“Come here,” Rocinante found herself interrupting, her voice husky with sleep and arousal. She lifted the blanket to her bedroll for him.
Law’s eyes darted back to her, excitement and lust shining in them as he crawled under her blanket, crowding up close to her.
“Have you done this before?” She asked, not really expecting much as she reached down, stroking her hand across the fabric of his underwear - they were white panties, which Rocinante found much cuter than she probably should.
“Y-yeah,” Law panted, much to her surprise, “with Doffy. Started when I was ten.”
“Oh good,” Rocinante said without thinking, “I won’t have to break you in.”
Law’s eyes - which had fluttered shut - snapped open, staring up at her in awe.
“Cora-san,” he breathed, and she could see the way his face flushed in the moonlight, “Cora-san that was - that was really hot.”
Rocinante giggled a little at him, pulling him closer, reaching into his underwear to stroke his stiff prick. “You’re cute,” she couldn’t help but tell him.
Law whimpered, bucking into her hand. It barely even took a few strokes and then he was cumming, splattering her hand with his load. She pulled the appendage out carefully, before bringing it up to her mouth and lapping up Law’s seed. She could hear him make a choked noise, but she ignored it.
“You came pretty quickly,” she said, trying not to let her disappointment show.
Law sat up, looking at her hopefully.
“Can I touch you, too?” He asked, blushing and fidgeting.
“Please do,” Rocinante said as she rolled onto her back, lifting her hips so she could quickly remove the shorts she slept in.
Once they were tossed aside, Law was eagerly slotting himself between her legs, his dexterous fingers finding her clit without fail. Doffy had taught him well, she thought; she had been with a couple of men who couldn’t find a clit if she gave them a fucking road map.
“Can I eat you out?” Law asked, looking up at Rocinante with pleading eyes.
“Of course,” she said, spreading her thighs a bit wider to accommodate.
Law practically dived down to get his mouth on her cunt, his tongue slipping inside her with no resistance, expertly stroking her inner walls. His fingers returned to her clit, rubbing it in a circular motion.
With three years of experience under his belt, it was no surprise the kid was intuitive; he quickly adapted to exactly what she liked, paying close attention to her reactions, finding what made her moan and squirm without fail, then targeting those weaknesses without hesitation.
It took her probably close to fifteen minutes to cum, but even that was still quicker than she’d managed by herself before this little trip had started. (And quicker than most men she’d been with).
And then, after she came, Law pushed onward, continuing his ministrations through her orgasm and beyond it as well, pressing into her oversensitive clit and practically ripping a second orgasm out of her in less than three minutes, her hips stuttering and her toes curling.
At that point, Law pulled away, much to her relief. Her chest heaved with the exertion of two Earth-shattering climaxes in a row, her body drenched in sweat.
“Was that good?” Law asked.
Rocinante picked her head up to look at him incredulously, just in time to catch him licking her fluids from his hands. She could see the way it stretched between his fingers, sticky and viscous. With a groan she slung her arm over her eyes - it was far too soon for her to get turned on again.
“I can’t fucking believe I just got the best head of my life from a thirteen-year-old,” she complained.
“I can’t tell if that means I’m really good or most men are just really bad,” Law replied mildly, followed by the sound of lewd slurping.
“Both,” she grumbled, moving her arm a bit to crack one eye open at him. He had moved on to the other hand. Had she really made that much? But then, she was so much larger than him.
“You know it’s really fucked up for a thirteen-year-old to be so good at eating pussy,” she said crudely.
“It is?” Law paused in his... clean-up efforts to look at her with curious eyes. He looked so cute when he looked at her with his big gold eyes, she thought, especially when she could see his cock standing at attention again in his underwear.
“God this is so illegal,” she groaned.
“We’re pirates,” Law pointed out reasonably.
Which. Wasn’t technically wrong? Her loyalties had shifted more than she liked to admit during her time by her sister’s side.
“Good point,” Rocinante said, bringing her arms down to strip her shirt off as best as she could without sitting up. Might as well go for broke she supposed.
“Oh,” Law’s eyes went wide as they landed on her bare breasts for the first time.
They were more than above average, she’d admit, but they were nicely proportioned to her well-muscled hourglass figure. Of course, with their size difference that meant each one was about the size of Law’s head and probably weighed about as much too.
“Clothes off,” she told him, “then come here and straddle my stomach.”
Law scrambled to obey, clumsily pulling off the over-large shirt and his little white panties, then awkwardly crawling to position himself as ordered.
He flushed underneath her intense gaze as she looked him over, eyed the way his cock leaked on her chest. She gripped him by the hips and pulled him forward until his dripping cock was pressed against her sternum, right in the dip between her breasts. For a moment, Law looked confused, but then Rocinante grasped each of her breasts and pushed them together, practically engulfing Law’s prick in their soft heat. She squeezed, and Law’s hips bucked instinctively, his pre-cum smearing and making his cock glide between her tits with ease. He moaned, his hands coming down to grope her chest, his palms barely even big enough to span the width of her nipple.
Within seconds, he was rutting into the warm, wet channel her tits created, chanting her nickname so cutely as he pistoned his hips as best as he could, his little cock leaking so much pre-cum she could see and feel it seeping between her tits and down her collarbone and stomach. He leaned into her chest, his hands nearly sinking into the soft flesh of her breasts, and she barely even felt it he was just so much smaller than her. He was staring at her in awe, his eyes wide as they flickered between her breasts and her face. Had he never done this before? She wondered for only a moment before realizing that her sister didn’t exactly have the... assets for it.
Eventually, his hips began to stutter, his climax obviously approaching. Rocinante moved her breasts in time with his frenetic thrusts, rolling them in her hands, letting them fall farther apart then pressing them tightly together again, mimicking the clenching rhythm of a tight hole, until finally, Law came with a cry, his cum splattering over the tops of her breasts and hitting her cheek.
He slowed to a stop, his chest heaving. His skin was flushed from his face down to his chest, his white patches turning pink. He swayed a bit, and Rocinante gently gripped him around the waist and laid him down next to her before he slumped over. He looked up at her blearily, his eyes flitting over the splatter of cum he’d left on her cheek and chest and neck.
“I’ll clean up my mess in a second,” he mumbled.
“No need,” Rocinante told him, already scooping up some of his seed and moving her hand down to shove into her cunt. She repeated that motion until most of the remnants of his load were inside her, then began to finger herself with it.
Turning her head to look at Law revealed him staring at her moving hand in awe, somehow already getting hard again. Ah, the wonders of the teenage refractory period.
Rocinante fingered herself languidly, her eyes catching Law’s when he looked back up at her face. With her free hand, she beckoned him closer to her.
“Come kiss me,” she told him, and somehow that made him flush harder than anything they had done so far.
Still, he sat up again, leaning down to press his lips to her’s. When she opened her mouth, sliding her long tongue out, he obligingly opened his own, latching onto her tongue and sucking lewdly. Doffy must have taught him that one, she thought, shuddering with arousal.
Eventually, Law pulled away, his chest heaving, his face flushed.
“Cora-san,” he whined, fidgeting, “I’m hard again.”
“Fucking teenagers,” Rocinante huffed with a laugh.
She pushed Law down onto the bed roll, moving so she could straddle him. She hovered over him, spreading her cunt wide with two fingers. Slowly, she lowered herself onto his little cock, careful not to put too much weight on him.
“Did Doffy let you do this?” She asked, clenching around him and rocking her hips slowly.
“O-only a few times,” Law panted, “as a reward o-or a present.”
“Her loss,” Rocinante said smugly, finding a rhythm that made Law moan loudly.
He didn’t last long, not that she expected him to. She was a little surprised that he still had anything left to shoot, but she enjoyed the pleasant warmth filling her, nonetheless.
She held herself slightly above Law, letting his cock slip out of her body as she reached down to continue jerking off. She brought herself to orgasm very quickly with the warmth of Law’s cum inside her, the boy himself naked and panting beneath her, looking at her with such reverence, like she was a goddess in human form. She could say with complete honesty that she had never truly understood why her sister enjoyed considering herself a goddess, but for a brief shining moment, as Rocinante looked into Law’s worshipful eyes, she understood just a little bit.
She laid down again, dragging Law into her embrace, curling up with him. He nuzzled sleepily into her breasts, smiling up at her.
“Thank you, Cora-san,” he said, sighing contently.
“Don’t bother asking next time,” Rocinante told him, stroking his hair. She flushed a little bit as she spoke, telling him, “just jerk off over me if I’m asleep.”
Law blushed a bit, fidgeting in her hold, avoiding her gaze. He mumbled something.
“What was that?” Rocinante asked.
“I’ve... done that a few times,” Law said a bit louder. “I never came on you of anything!” He added quickly, “I just... you’re so pretty. I couldn’t help myself.”
“I really shouldn’t find that cute,” Rocinante told him, pressing a kiss to his forehead. Law relaxed against her again.
“If we’re doing honesty hour,” she said after a moment, “then I should tell you - sometimes when you have wet dreams you cum in your sleep.... and I uh. I like listening and watching.”
Law flushed a bit. “That’s been happening a lot less lately,” he mumbled.
“Actually...” she looked away, a little embarrassed, “I just... started shifting a little bit until your underwear slid down enough that you could cum against my skin.”
Law’s eyes went wide as he gaped up at Rocinante.
“Wh-what did you do with it?” He asked, “I always wake up when you get out of bed before me!”
“I uh. I fingered myself with it like I did earlier,” Rocinante admitted.
Law made an incomprehensible noise that sounded something like ‘agafajkdajfsa.’
“Cora-san,” he choked out, “what were you gonna say if you got pregnant doing that?”
Ah, trust Law to be smart enough to notice that.
“To be fair, I have very low chances of getting pregnant in the first place,” Rocinante defended herself, “I was actually thought to be completely infertile until I was about 20.”
“Very low isn’t zero,” Law huffed at her.
“Meh. Whatever. My chances are less than 1%,” she shrugged, “and considering our combined horrible luck, I doubt I’ll be lucky enough to actually get pregnant.”
“Lucky??” Law looked up at her in confusion, “... do you... want to get pregnant?”
“I’ve always wanted kids,” Rocinante sighed, “never found someone to give me any.”
“I thought you hated kids,” Law blinked up at her.
“Ah. That was a lie,” Rocinante admitted, “I just wanted to drive as many kids away from piracy as I could.”
“You know, for someone who’s burned down so many hospitals, and threw me out a window, you’re kind of a softie,” Law told her.
“I dunno about soft, but I certainly am the nice sister,” she said reasonably.
Law nodded in agreement, yawning and finally settling down to sleep.
“Cora-san,” he mumbled as he was drifting off, “if you do get pregnant, I promise I’ll be a good dad.”
Rocinante’s eyes softened at the boy in her embrace as she leaned down to bury her face in his hair.
“I’m sure you would be,” she told him quietly.
