Laying on your bed in nothing but your panties and t-shirt, you bit your lip, slowly moving your hand downwards towards your panties. You felt so guilty, so dirty, thinking about them like this, they were your brothers, but it always made you so hot, imagining them taking you, imagining their hands instead of your own. Your hand slipped under your panties, rubbing circles on your clit. It wasn’t like they knew what you were doing and they weren’t actually related to you, so it wasn’t so bad, right? Your other hand wandered up under your shirt, playing with your breast, pinching and pulling your nipple as you let out a quiet whimper. It was wrong to imagine them, wasn’t it? To imagine that they were playing with you, taking you. Slipping a finger inside your pussy, you couldn’t help the slight pleasured gasp that left your lips, fingering yourself faster and faster.

“S-Saboo, Ace~” you whined, thinking of the two older boys. You felt hotter than normal as you squirmed, wanting more. It never felt like enough, you wanted, needed more. You needed them, needed their cocks.

You weren’t entirely sure what time it was when you finally finished, only that you were left tired and still horny. That being said, you knew that you didn’t have enough time for more, it was starting to get dark, meaning the two would be over soon for ‘movie night’. Your weekly hang out with the brothers where you all ate too much junk food, watched a movie, and, more often than not, passed out in a pile on the couch. You were starting to curse the fact that it was just the 3 of you, leaving you to be sandwiched between the older 2 boys. It wasn’t that Luffy wasn’t invited, just that he either forgot, or was doing other things these days. Almost as soon as you’d pulled your clothes back on, you heard the front door unlock. You might have to take that spare key back from them, less they walk into your apartment while you were ‘busy’ and overhear what you were doing, or worse, what you were fantasizing about.

“Y/n! We’re here!” Ace called out, smiling when you hurried out to meet them.

“‘Bout time! I was starting to wonder if you’d forgotten.” you teased, moving to hug him only to snatch the bag of snacks while he thought you wanted a hug. You couldn’t let them know how you felt about them, so you’d play the ‘sweet, innocent little sister’ like you always did… or well, almost always.

“Sabo, she stole my snacks and didn’t even give me a hug.” Ace whined, not bothering to try and get the snacks back while you rifled through the bag.

“Then maybe you should stop falling for her tricks? Or just hand her the bag next time?” Sabo said, nudging Ace out of the way, only making Ace pout more.

“Don’t bother, princess, those are entirely Ace’s, I’ve got yours right here.” the blond said, shaking one of two bags in his hand. Almost immediately you were handing the bag back to Ace and following Sabo almost like a puppy. Not that he needed snacks to get you to do that.

“And still no hug?!” Ace demanded, holding his snacks once more, still pouting as he joined you and Sabo in the kitchen.

“You’re 21 and you’re still whining about not getting a hug?” you teased, wrapping your arms around him.

“He’s just a child who can’t just hug you himself because then he’d have to admit that he actually likes hugging people.” Sabo said, wrapping his arms around your waist, his hot breath blowing against your ear, making your cheeks darken. He was so close, you could feel his muscular chest against your back through his shirt. With Sabo against your back, you didn’t notice the look he gave Ace before backing off, returning to his snacks, gathering his things before setting them on the coffee table.

“S-so what are we watching tonight?” you asked, trying to will your blush to die down.

“Eh, not sure, ask Sabo, he picked.” Ace said, waving dismissively as he dumped his own stuff on the coffee table.

“Oh please not another political movie!” you groaned, remembering the last time Sabo had chosen the movie.

“You guys act like it was a death sentence! And I mean, I suppose it counts as political but I swear you’ll enjoy it!” Sabo offered making you sigh.

“Fine, fine, pull it up.” you asked, taking your spot between the two. Why they always insisted you sit in between them, you’d probably never know, but it was ‘your spot’ and there was no changing it. Sabo grinned as he pulled the streaming site up and started the movie. About halfway through the movie and you couldn’t stop fidgeting. The two brothers seemed to be extra close today, Ace resting his head on your shoulder, breath hot against your neck and Sabo’s hand resting just above your knee, rubbing unconscious circles on your thigh with his thumb.

“C-can I get up?” you asked, gently pushing against Ace. you needed to get out of this position before they drove you crazy. You could already feel the desire burning low in your stomach, making you hotter and hotter with each passing second.

“But I’m comfortable here. Do you really need to get up?” Ace asked, voice low, words practically whispered in your ear. His mouth was so close to your skin, you could almost feel his chapped lips against your neck.

“I mean, I suppose we could let you up, but then we’d have to reposition once you get back.” Sabo said, giving you a smirk that had the low simmer in your stomach turning up to a boil. Why did it feel like they were being so flirty?

“I expect something in return if you make me reposition when I’m so comfy.” Ace demanded, your heart racing.

“F-fine! You can have all my remaining snacks! I just… I need to get up.” you said, hoping that he’d go for it. He was a bottomless pit, surely he’d just want your food, right?

“Mm, not what I want.” Ace said without hesitation, confusing you. If he didn’t want your food, what did he want?

“You’re going to share, aren’t you?” Sabo asked, giving Ace a look that you couldn’t quite decipher.

“Yes, yes, I’ll share… so long as it’s okay with her.” Ace muttered, nuzzling into your neck, turning your cheeks an even brighter red.

“S-so long as what’s okay with me?” you asked nervously. You tried to shake your thoughts away, you were reading too much into this, you had to be. Sabo just chuckled, placing a hand under your chin, turning your head to face him before pulling you into a rough kiss, his hand moving to the back of your head, fingers tangling in your hair as he stole your breath away. A light, pleasured sigh left your lips as you felt Ace nipping at your neck, teeth lightly scraping against your skin.

“You don’t mind, do you, Angel?” Sabo asked once he pulled away, leaving you a little lightheaded.

“I… I don’t but…” you bit your lip, eyes looking away shyly before meeting his once more, “it… it’s wrong. We’re…” once again you trailed off. They knew what you were saying even without saying it.

“Not as bad as you think, we’re not related by blood.” Ace muttered, giving a particularly rough bite to your shoulder, drawing a small yelp from your lips at the sensation.

“We know you want it, Angel, we see the looks you give us… we know the things you’ve imagined.” Sabo said, the last part whispered to you, turning your pink cheeks into a full blush that you just knew went all the way down your neck. You did want that, you wanted it, wanted them, so badly. Sabo pulled you into another kiss, distracting you from what they were doing until you felt Ace’s hand under your shirt, groping your breasts through your bra. The blond in front of you swallowed the whimper that left your lips, his kiss growing rough, only pulling away when breathing became a must.

“Well, princess? Do you want us or not?” Ace asked, making you swallow hard as you nodded.

“Yes, I-I, I want this, want you.” you admitted, a surprised squeak leaving your throat as Ace picked you up, carrying you back to your room, Sabo following close behind. Almost as soon as the door was closed, the two of them were undressing you, hungry eyes roaming over your now bare form.

“Fuck, Angel, so many things I want to do to you.” Sabo said, thumb flicking over one of your nipples, making you whimper slightly. Their hands felt so good against your skin, making you want more.

“Please.” you whispered, looking away. You still couldn’t believe you were doing this with them, finding it hard to voice your desires.

“Please what, princess? You’re going to need to be more specific.” Ace said, placing featherlight kisses over your body, working his way up from your thigh to your neck and back down again.

“Please… d-do whatever you want to me.” you said, voice just above a whisper. A shudder went down Sabo’s spine at your words, whatever he wanted? Fuck, he didn’t think you could take all the things he wanted to do to you.

“Careful, Princess. Sabo’s a little sadistic.” Ace said, seeing the dark look in his brother's eyes.

“I didn’t hear you complaining last week.” Sabo shot back, making Ace swallow hard as you looked between the two. Had they been…? “Don’t worry, Angel, I’ll take it easy on you tonight, besides, I don’t think I have everything I’d need.” Sabo said, caressing your cheek, only to have Ace chuckle, drawing both your attention, watching as Ace emptied his pockets of what looked like a length of rope, a small pink vibrator, a pair of handcuffs, a blindfold and a gag.

“Do I even want to know how you fit all this in your pockets without me noticing?” Sabo asked, picking up the handcuffs.

“Do you really care so long as you get to use them?” Ace asked cockily, only for Sabo’s hand to reach around behind Ace, gripping his hair and making the older boy groan.

“I’ll use them on you if you’re not careful.” Sabo hissed before pulling him into a rough kiss. You could feel yourself get wetter as you watched the two make out for a moment before Sabo was pulling back, leaving both boys breathless. Looking back at the various items Sabo couldn’t help but smirk as he shook his head.

“Got everything important except my new toy. I suppose it’ll be fine this time, don’t want to overwhelm her.” he said, thinking about the cane he’d left at home. A new addition to his collection, one he couldn’t wait to use. Both boys were soon back on you, cuffing your hands behind your back before tying the rope around your body, hands trading the rope until you weren’t sure who was holding what end or where the rope was even going. Finally, they pulled away, Sabo giving you a dark look. Your calves were tied to your thighs, the binds accentuating your breasts, before wrapping loosely around your neck like a makeshift collar. Wriggling slightly, you pulled against the ropes, finding the knots to be secured rather well.

“You still okay with this, Princess?” Ace asked, groping and massaging your breasts, drawing pleasured sighs from your lips.

“Y-yes, I… more.” you whimpered, arching your back into Ace’s touch, moaning lightly when he pinched your nipples, rolling them between his fingers. You were soon too preoccupied by what Ace was doing to pay attention to what Sabo was doing until you felt vibrations against your clit, forcing a loud cry from your throat, arching further into Ace. Your cries seemed to spur Ace on as he started sucking on your nipple, pulling and rolling the other between his fingers.

“Fuck, you look so good like this, completely at our mercy.” Sabo groaned, running two fingers up your slit as he kept the vibrator pressed against your clit, making you moan more, “fuck, so wet too, have you been thinking about this all night?” he demanded, your slick coating the tips of his fingers. Reluctantly, you nodded, biting your lip as you did so. You couldn’t deny it, not when he was making you feel so good. Ace pulled you in for another kiss as Sabo thrust 2 fingers inside your pussy, the black haired brother swallowing the moan as he made out with you. It all felt so good, having Ace play with your tits while Sabo fingered you and played with your clit, making out with Ace while your head spun from the sensations.

“You still want more, princess?” Ace asked, pulling away slightly, watching as you nodded.

“Please. I… I want you, both of you.” you whimpered, pulling at the ropes, only for Sabo to give another dark chuckle.

“You’re gonna have to beg if you want more, unless you want me to keep you like this all night. I could, you know. Tied up with the vibrator pressed against your clit, just low enough to keep you writhing in pleasure until you’re about to go crazy from need. Maybe I’ll make you watch as Ace and I get off. Watching us cum, half delirious as you try to beg me to fuck you.” Sabo said, making you whimper.

“No, no please don’t. I want more, I want you. I’ll do whatever you want, just please, more.” you pleaded, admittedly turned on by what Sabo was saying.

“Come on, Sabo. Don’t tease her, how is she supposed to come crawling back for more if we don’t give her any to begin with?” Ace asked, biting and nipping at your neck and shoulders, leaving small marks all along the skin there.

“You’re lucky that Ace makes a good point, pet. Otherwise I might just leave you a whimpering mess.” Sabo said, fingering you harder and faster until you were cumming, soaking his fingers.

“Mmm, looks like my dirty little pet made a mess.” Sabo said, pulling his fingers out of you, though keeping the vibrator pressed against your clit, making you writhe in pleasure.

“I’d be more than happy to clean it up.” Ace chimed in, taking Sabo’s hand, starting to lick and suck your juices off the blond’s fingers. All you could do was watch, feeling even more turned on, if it was even possible.

“Shit, I think you might be as big a slut as she is. Bet you can’t wait to fuck her, hell, I’d bet you’d give anything just to taste more of her.” Sabo said, watching as Ace finally finished licking his fingers clean.

“You can’t tell me you don’t want her too, not with how much you moan her n-” Ace was cut off by Sabo yanking his hair again, Ace’s breath hitching as the blond held him.

“You’re testing my patience, Ace. You know what, I know exactly what to do to kill two birds with one stone. You’re going to sit there and watch, you’re not going to touch her and you’re not going to touch yourself, got it?” Sabo growled, watching as Ace swallowed hard but nodded. Sabo quickly stripped, tossing his clothes to the floor before picking you up, spreading your legs so Ace could see your pussy as Sabo sat behind you, thrusting his cock inside you, making you cry out in pleasure. Ace groaned as he watched Sabo fuck you, throwing his own clothes to the floor, quickly finding them too tight for comfort.

“Fuck, so good, pet, so tight, squeezing my cock.” Sabo moaned, bouncing you up and down on his large cock.

“Y-yes! Please, more! Fuck me more.” you moaned, head thrashing side to side as you struggled against the ropes.

“At least one of you knows how to behave. Maybe I should’ve tied Ace up instead of you. Later, I suppose. If you’re a really good girl, maybe I'll let you play with him.” Sabo whispered into your ear, making you lean your head back against his shoulder as you moaned loudly.

“Yes, please! I’m a good girl. Please, fuck me more, make me cum!” you pleaded. In front of you, Ace squirmed, gripping the sheets as he tried not to touch himself.

“Fuck, fine! I’ll behave, just stop keeping her all to yourself.” Ace groaned, his cock throbbing as he imagined being inside you.

“Oh look who wants to join in. What do you think? Has he been behaving well enough?” Sabo cooed, giving a particularly rough thrust that had you crying out.

“Yes, please, let him touch me. I want more.” you moaned, feeling yourself draw closer and closer to the edge.

“Cum for me and I’ll let him touch you again.” Sabo demanded, smirking when you came a few thrusts later, your pussy squeezing him tightly, milking his cock as he came inside you, “I suppose a deal’s a deal. She’s all yours, but I wouldn’t suggest testing me again.” he added darkly. Not that he thought Ace would listen, Ace was just as bad as he was when it came to not causing trouble. As soon as he was ‘allowed’ to, Ace was pulling you into a kiss, slamming his cock inside you. He needed you, needed to fuck you. Sitting back and watching, not being able to touch himself had made him painfully hard, a loud moan escaping his throat the moment he sunk his cock into your tight heat.

“Oh fuck, princess, so good, so tight.” Ace moaned, laying you on the bed before starting to pound in and out of your pussy, making you moan as well.

“Being such a good girl, aren’t you, pet? Taking Ace so well.” Sabo said, pulling you into a rough kiss. All you could do at this point was moan and writhe in pleasure, your eyes rolling back into your head as you came for a third time. Pulling Ace will you, both of you letting out twin cries of pleasure. Ace barely managed to pull out as he collapsed beside you, clearly a bit worn, giving a loopy smile as Sabo freed your wrists before loosening the ropes, allowing you to move.

“Don't either of you think we’re done tonight. I need a short break, but I’m far from finished.” Sabo said, making Ace smile and you shiver as you both nodded. You were both more than happy to go again, maybe this time he’d tie Ace up. Looking at you two, Sabo smirked, he’d definitely have to bring his new cane with him next time. He couldn’t wait to see what you’d look like with marks across your thighs and back. For tonight, he might just have to stick to spankings. Hopefully you’d ‘misbehave’ enough for him to warrant doing so. Then again, did he really need a reason?
