Dr. Stone Random Relationship HCs
Mostly NSFW
A lot of these are gonna be (almost grotesquely) NSFW. I’m just typing what I’m thinking honestly. And I’m keeping it real around here. This is the most out there thing I’ve ever written. So since it’s not my usual, I felt the need for specific warnings this time.
[Warnings]: size kink (if you squint), penetration, HJ, BJ, sub/dom, use of toys, and a reluctantly added piss kink (won’t tell u for who, find out), infidelity, unprotected sex, toxic relationship, dacryphilia, BDSM
Characters: Ryusui, Kinro, Tsukasa, Senku, Gen, Hyoga, Mozu, and Ginro
Guess who my favorite character is… impossible edition (it’s so obvious, you’ll know when you see it)
Nanami Ryusui
His dick is actually like uncomfortably big. (I’m writing these hcs bc I needed to get this out of my head into writing) (also I know that’s subjective, I’ve seen the crazy dildos ppl buy)
I’m talking almost 9 whole inches. And he’s a shower, not a grower. Even soft it’s fucking huge.
I’m right. I can feel it in my BONES. Yall seen the way the other characters stare at him when they revived him? I’m right.
He’s so cocky and proud of his size, but he’s not mean. He’s not like crazy careful, but he’s definitely the type to talk you through it as he slowly pushes it in.
“You’re taking it so well, beautiful.” “C’mon, look at it. Look how pretty you look wrapped around me like this…”
His favorite position is cowgirl, but he still does all the work. He looks up at you with a huge smirk while moving your hips for you.
He’s not very noisy besides groans and talking.
He is loyal, but he’s a bit different from the average person. He genuinely thinks all women, and men, are beautiful. He can appreciate that. But he’s not the type to stare at or touch their bodies with or without a partner waiting for him at home. But especially not with a partner. He’s respectful towards them AND you.
If his usual nature is bothering you, he’d never turn down a respectful conversation about boundaries. He’s likely to make some effort towards changes to make you more comfortable with his behavior.
But I think if you’re dating him, you’d likely see just how genuine his affinity for appreciating everybody is, and how it’s not lustful in nature.
Kinro
He’s so oblivious to flirting unless it’s obvious.
He takes relationships incredibly slow.
He’s fiercely loyal. If another person flirts with him, and he catches on, he’s stiff as a board and firmly mentions he’s not interested and is happily committed to another.
He’s pretty big… 7 inches.
Very shy first few times having sex with you. But he thinks very traditionally sometimes, especially if you’re a woman, and will nervously take the lead.
The lead goes basically nowhere and you have to slyly guide him towards the next action, but let him take over. Not for control, but because he wants to be the one taking care of you.
He’s very sensitive.
He loves when you run your hand down his chest… abs… and his face scrunches up and he bucks his hips up if you run that hand over the front is his pants too…
He prefers a handjob over a blow job because he loves getting to kiss you still or let you suck on his neck or chest…
Shishio Tsukasa
Soft dom. Soft dom. Soft dom.
He’s always in control. And unlike Kinro, it’s actually because he likes having some control over you. It turns him on. But he also doesn’t like to hurt or be mean, exactly.
He teases with a cocky grin, but it’s all because he knows even if you whine, you like it. Everything he does is for mutual pleasure because yes he gets off on your whines and pleads, but he’s getting off on knowing you want him and like what he does.
Foreplay takes forever with him. He’s got patience. I’m talking slow, passionate kisses and soft touches in places you didn’t know would turn you on until him.
More of a giver than a receiver.
Hot take? But he makes noise. Idc. This man lets a few whimpers slip if you do suck his dick for him.
Oh and ride him just right? Nobody would ever believe that THE Shishio Tsukasa becomes a weak, whimpering mess under you.
Trust me guys, I’m right. I found this all out from Tsukasa himself.
I didn’t wanna make everybody have dick hcs, but…. It’s abnormally big. Idk. I’m taking frighteningly girthy AND long. 10 inches probably. Likely never getting it all in. I feel like dude could probably like lift weights with it. His entire body is like he’s on steroids without the steroids in my eyes.
Ishigami Senku
Romance is not really on brand for him, especially at the moment.
But when he does fall? He falls harder than he’ll ever admit.
Now he knows to be logical and reasonable, you shouldn’t get absurdly special treatment just because he feels some type of way about you. He doesn’t need to invent a helpful machine or device that only benefits you.
So he’ll make something to make everybody’s day easier, but deep down, he knows he made it after seeing you frustrated with the long, hands on process you had to do for something that used to be so simple in the 21st century.
Along with that, he doesn’t have a super high sex drive. Not to mention, he’s busy.
So if you’re dating him, he’s probably made some sort of toy for you. Maybe a silicone mold of his dick… maybe a vibrator… something. For when he’s busy, away, or whatever.
When he can though, he takes his time. Not one for quickies at all.
He’s not always annoyingly scientific, at least out loud, to spare you. But he does view sex sort of like an experiment. When he touches there, it elicits a positive response. And he commits that to memory.
I think he’s autistic (as an autistic person myself) so I think almost everything comes back to his incredibly useful special interest, science.
He’s not very affectionate. Public or not. You usually have to initiate, but that doesn’t mean he doesn’t enjoy it. He longs for your embrace if he’s gotta go somewhere for a while without you.
He says he’s not the type to cry about something when he knows he’ll see you again soon, but some times the pain of losing his dad abruptly bleeds into worry about losing you or his friends. And when he’s completely alone, it gets to him.
Asagiri Gen
Kinky.
Sex with him often involves some sort of kink he’s into. Yet he’s rather soft with it in a way that’s like usually spiritually vanilla.
I’m getting the feeling he would want to blindfold you then whisper in your ear and ghost his fingers along your body.
He will find a way to be a bit annoying tho. He will stick his tongue in your ear. However, it’s not all to be annoying, he knows it’s an erogenous zone.
He loves denying you orgasms or ruining them. Especially ruining them. He loves not working you through it and watching you whine because you came, but it wasn’t the entirely satisfying kind.
His dick jumps a little watching you squirm and whine because you’re so sensitive after a ruined orgasm.
I accidentally read a fan-fiction once bc it was late and I missed a tag on Ao3 and well… Gen had a piss kink. And I reluctantly must admit… it’s a little gross and usually against my brand here, but I can kinda see it. I think he would like trying not to pee while you give him a hand job, but he refuses to be inside you in any way. And vice versa, he likes when you’re trying not to pee on his hand.
The type to set the mood. Candles, music, foreplay.
He’s a switch.
I can see him being into being on the receiving end on most of his kinks.
Akatsuki Hyoga
It’s usually rough. His favorite position is doggy, but he’s pulling at your hair as he bullies his long cock into you.
And it’s long. About 7 and half inches.
The type to make you cum multiple times before he cums, but necessarily out of the goodness of his heart, it just happens. He takes a bit to finish, but the efforts to get to his end are enough to drive you crazy.
With him, he’s so good with his dick, he doesn’t need to help you out by touching you anywhere else. Penetration is enough. Though sometimes he’ll tell you to touch yourself for him.
He’s very trusting of you in a way he will NOT control how you interact with others or go out, but he’s controlling a dominant way.
He doesn’t like it if you touch yourself without permission.
100% into BDSM. Especially if he catches you breaking a rule he set, you’re getting tied up and fucked until you’re crying. And he’s such a sadist, he loves when you cry.
You have to have a safe word with him. He’s mean.
But even Hyoga has his moments. He values those soft moments too. There are rare times when you come home and there’s candles lit, soft music playing. And he’ll sneak up behind you and wrap himself around you from behind, taking off your clothes slowly.
He’ll kiss your jaw, your neck, your shoulder, your back, meanwhile his hands are on your chest.
On another note, he’s not into PDA. Nor he is ever really much of an affectionate boyfriend beyond small things.
He may brush your hair out of your face or briefly place a hand on the small of your back when he’s talking to you, but it’s not ever much else.
But he cares a lot in his own way. He stays close. Like your shadow; a very threatening, intimidating shadow.
More than likely, you can take care of yourself. He knows that very well. He’s not one to make a lover of somebody who can’t take care of themself, one way or another. However, none of that matters too much in this instance when to him it’s more so about his loyalty and respect for you than you needing his help.
He takes him a long time to actually get into a relationship. For months on months, it’s just him making small comments and compliments on what you’re doing that send you into a spiral wondering what he means.
He’s extremely loyal to you, though he’s not the type to go around telling people unprovoked.
Most people have a suspicion that you’re together by the way he’s this looming presence somewhere in the area.
He trusts you to handle situations, but sometimes a person takes things too far, and he’ll step in. He makes it clear you have a boyfriend, one who won’t be so merciful if the person has the nerve to continue on.
If you break his trust, there is no second chance.
Mozu
He’s not loyal in the least of ways, but if you cheat? He’s pissed. Yet, not enough to leave you.
The relationship would be toxic. TOXIC.
A manipulative bastard.
“Oh come on. At the end of the day, I’m coming home to you. You’re more important than those girls… it’s just fun.”
He swears there is nothing emotional or deep with the girls you catch him with, nor does it say anything about his love for you.
Obviously, if you’re gonna withstand him, you gotta be the type to be equally as awful. He hates it, but that fuels hate sex so…
If he catches you sleeping with another man or gets the suspicion something is going on? He’ll fuck you so good you forget all about why you told yourself to leave him…
Sex is competitive at that point, with both of you making sure the other knows who can fuck them the best.
“Cmon… I know he doesn’t have you screaming like this… mm…” he’ll groan as he shoves himself in as far as he can go and cums deep.
With you, he always wants it raw.
If you’re lucky, he’ll admit you’re his #1.
“She didn’t take it as well as you always do… none of them do.” “They’re not as fun…”
He’s always in control.
Ginro
Contrary to possibly popular belief and my previous beliefs, he’s mostly loyal. I wanna start this off by saying that.
I also really like Ginro for some reason.
But anyways, he’s not perfect dream boy type of loyal tho… he’s a bit lustful. He would probably occasionally look at another woman.
He’d be the type to get distracted, but never cross the line past a brief glance or thought. He’d cut off a girl as soon as he came to his senses.
He wants to be in control during sex, but he never is. He’s always a mess, crying and whimpering as you ride him.
His dick is small. And he honestly isn’t great at using it. He tries though.
Realistically, you’ll probably have to teach him how to touch you and how to make you feel good.
He cums quickly. Like 10 thrusts and busts… but he’ll apologize over and over again.
He works hard to impress you. Kinro and the others appreciate your presence because Ginro will work so much faster.
A positive about him? I could see him being like madly in love with you. Like talking about you to Kinro while they guard the bridge, stars in his eyes.
You’ll have to be a saint to deal with him, honestly. He’s not the best boyfriend in a lot of ways, but he tries.
Gods, I love pathetic men.
