WARNINGS/TAGS: Fem! Reader x Robin, (step)brother!Robin — can be read as incest OR stepcest, horniness overriding rationality, just a bit of dubcon if you squint (everything is fully consensual but there's some initial hesitation), a pinch of dacryphilia from reader, Robin is kinda codependent and reader encourages it, oral sex (and virginity loss), premature ejaculation, facials (the cum kind), small dicks appreciation, Robin is a crybaby (integral character trait)

To you, there's no one cuter than your baby brother. Other people might have an issue with how meek he is and think he's a freeloading pushover that you baby too much. Maybe he is. You don't care. He's so sweet and so incredibly attached to you, always trailing after you and looking at you like you've hung the moon and the stars. He's been like that for as long as you can remember. And, well, can you really be blamed for enjoying your ego being stroked when he asks you for help and guidance in everything? Robin is so reliant on you. He'd be lost without you. Knowing how much he needs you honestly makes up for the inconvenience of him relying on you even in things he should be able to handle by himself. There's just something so adorable about Robin coming to you and only you.
That's why you're very thrown off when he suddenly refuses to tell you what's bothering him and insists he can deal with it himself. He's all flushed and avoids your gaze when you start probing for answers and it's immediately obvious he's lying. Robin's never been a good liar, at least not when it comes to you. So, like a good older sister, you decide that you must find out what's wrong.
To Robin's credit, he does try to evade your questions and makes up several excuses before he starts cracking. A valiant effort that's rather undermined by the fact that he starts tearing up and throws himself into your embrace the moment you press him a bit harder. It takes some effort to decipher the words between his sobs and sniffles. Something about him being gross and not wanting you to hate him? You've always been aware that your baby brother is a bit melodramatic, but this is silly even for Robin. Why would you ever hate him?
Some soothing later, he finally starts opening up. He's being as evasive as he can and refuses to come out and say it directly, but you manage to pry more information out of him. Apparently, he's a pervert. Robin's words, not yours. It makes your heart ache to see him so distraught, so you try sharing some of your own kinks in an attempt to reassure him that it's alright. You get sidetracked along the way and go into great detail about what exactly makes you wet, cutting yourself off only when you see Robin squirming in his seat, covering his crotch in an almost comically obvious way.
Well, fuck. You've given your own brother a boner. Before you can even decide what to do, Robin is bursting into tears again. Turns out he's already been struggling with getting boners around you and feels ashamed of himself. He looks so damn pitiful when he confesses this to you, grabbing at your shirt and wiping his eyes with a shaking hand. You're aware that it's not a good idea, but the temptation to tease him is too strong. Maybe you have a thing for crying boys. Or maybe it's only Robin that has that effect on you.
You slide your hand between his thighs and inch up towards his bulge. Robin immediately looks alarmed and even more embarrassed, but his thighs traitorously fall apart in anticipation of your touch. Then you cup his cock through his jeans and he's immediately bucking into your hand, followed by wide-eyed stammering about this being wrong. He has a point, sure, but how are you supposed to take Robin's words seriously when he's currently trying to covertly hump your palm? You chuckle and give him a loving squeeze that earns you the prettiest moan you've ever heard. Robin's in tears but he leans towards you anyway. It's as if he's looking for comfort from his big sis, how adorable.
You keep stroking and squeezing his cock through his jeans and it doesn't take long at all for your baby brother to abandon his weak protests. They turn to pitiful apologies that spill from his lips along with moans while he humps you like an unruly pup who hasn't been trained out of it. It's honestly stunning how frantic he is, grinding his bulge into you while begging for forgiveness and saying how sorry he is. He clearly can't stop himself from moving his hips. You knew he's a virgin, sure, but this is just embarrassingly needy. And yet you find it cute.
A part of you wants to see Robin cum in his pants and then tease him for it. Another part is turned on too and wants to make the most of this situation. After all, Robin will probably be so embarrassed once post-nut clarity hits! You should try more things before he runs off to hide in a self-made corner of shame. That's why you force him to stay still for a moment and pull his jeans down. There's already a wet spot on his boxers and he sniffles with embarrassment when you point that out. At the same time, his cock gives a traitorous twitch under you gaze. Maybe you're both getting off on this a bit too much.
You don't dwell on the thought and instead move to wrap your hand around Robin's cock so you can jerk him off. It's small enough to be mostly covered by your palm, which seems to fluster your little brother even more and he starts stammering out apologies for his size. But you will not stand for his self-deprecation. Smalls cocks are cute! You've always thought they were much prettier and appealing, honestly. And you can take all of him into your mouth without too much struggling, something you happily demonstrate by wrapping your lips around his tip and slowly sliding all the way down until you lovingly kiss the very base of his shaft, your tongue sliding away from the underside to give his balls a playful lick. Robin has to try really hard not to cum immediately and you even feel his cum rushing under the skin before he manages to hold it back. Just barely. It's not his fault your mouth is so warm and wet and nice and it's his first time ever using anything but his hand, alright?
You know there's no way he'll last much longer. So you decide to suck him off with gusto, giving Robin a proper big sis blowjob. Unfortunately for you, your eagerness leads you to carelessness and you manage to make yourself gag on Robin's cock. You pull off immediately, coughing and sputtering while drool leaks down your chin. Before you can even get your breathing under control again, your face suddenly gets splattered with something hot and thick. It gets everywhere, including your hair and even a bit in your eye. You're lucky it was closed before your little brother's sperm landed there. When you wipe your eye clean and look up at Robin, he looks mortified. He is, of course, apologizing and swearing he didn't mean to cum on your face and he really was trying to hold back but you looked so pretty on your knees for him and you gagging while sucking him off was so hot and...! But all the excuses he's offering you don't have a lot of weight when you can clearly see him shyly fisting his cock in an attempt to milk out any leftover cum and prolong his sudden orgasm.
Robin's lucky he's so cute and you're so nice. Other big sisters might've gotten mad, but all you do is coo at him and offer a clean-up blowjob. He looks a bit panicked at the idea of more stimulation and shakes his head at first. But then he has to watch you swipe his cum off your skin and suck it off your fingers, and suddenly he's changing his tune all too quickly. Greedy, greedy little brother. He still gets overstimulated just like he feared and cries because of it, but he seems to not regret it when you reward him with cuddles afterwards.
You end up comforting Robin and promising you don't hate him at all. It's not that big of a deal that he gets boners around you! Just a natural physical reaction that says nothing about his morals or his attraction to his own big sis. Totally. You both go along with that explanation for a while and it seems like things are back to normal. Until Robin sneaks into your bed at night, clinging to you while crying.
He... Can't cum anymore? A quick experiment shows that he very much can, he just needs your involvement to do that. His own touch isn't enough anymore. Oops. Looks like you'll be stuck helping your little brother jerk off from now on. Since you're the one who started it and took his virginity, it's only fair that the responsibility falls on your shoulders, right? And it's not like it's a big deal! You've already been spoiling Robin and doting on him for so long, this is just another thing that you will do for him. Why should he find ways to deal with his problems himself when he can just let his big sis solve all his troubles and rely on you? You both prefer when Robin depends on you and you know it.
So of course you won't let your precious baby brother suffer from being blue-balled all the time! Not when you can have so much fun watching him cum his brains out with just a few of your touches or words ♡
