Chapter Text
“O. O, come back.” He pets her hair. “O, listen to me. Yeah. Okay. Yeah. I’ve done this before. That’s where I learned the stuff I’ve been teaching you. But it didn’t feel like this with anyone else. Okay?”
Doesn’t open her eyes, but softens. A little better.
“I didn’t feel anything, not really. It was like .... like when you saw me do it in the shower, it was just to get that feeling. Just to forget, for a few minutes. It wasn’t like this.” She turns back, opens her eyes. “Never like this, O. Never this good.”
“Am I good at it?”
Scared to ask what she really wants to ask, Do I make you happy, am I enough?
“Maybe it’s only really good if it’s someone you love,” he says, voice cracking. A little more real than he’d meant to be. Showing her stuff he normally wouldn’t. “And you’re the only person I love, O. You’re the only one I want.”
The smile lights up her face. She’s back. He didn’t lose her.
Nobody else matters but you,” he tells her, and she knows from the clench of his jaw that it’s real.
“I’m sorry,” she says, but he shakes his head, no, don’t apologize, you didn’t do anything wrong, I fucked up and didn’t even know it, all this time I had no idea I was waiting for you. But he won’t be able to hold the tears back if he tries to explain it out loud, so he just kisses her and hopes she’ll get it.
Hips shift. Skin on skin. Back to what they were doing before.
Oh.
She gets it.
He fucks her like he has something to prove, fucks her like he needs her to know that his whole body is made of love, that he’s all hers, that there’s nothing he wouldn’t do to make his baby sister happy. He fucks her until she comes, gasping, he can feel the sticky heat on his dick, but he doesn’t stop.
Sweat in her hair, shock in her dark eyes. What the hell is this and where has it been all her life? What is he doing to her? Fingers dig into his back. She doesn’t have to say “More, please,” she doesn’t need to wait, she can just take it, just lock her thigh around his and lift and take what she wants, which is all of him. The whole fucking thing. Right down to the base. She’s wet enough now that it goes in without a fight, but she’s not prepared for the pressure, and his hand clamps over her mouth just in time. It’s almost a scream, the sound she makes as he bottoms out inside her, it would get them in trouble for sure. He holds still inside her until she quiets down. “Sorry,” she whispers. “Sorry, sorry. I forgot.”
“S’okay.”
“It just surprised me.”
“I know.”
“You can keep going.”
“You sure?”
“Yeah. Yeah. It’s really good, Bell. I like it like that. The hard way. I really like it.”
“You sure?”
“Yeah.”
“Want more?” She nods. “Okay, want to learn the word for it?” Eyes light up. O loves new words. “’Fucking,’” he says. “You heard that before?” She shakes her head. “Don’t ever say it in front of Mom,” he cautions, “but that’s what it’s called.”
She nods, the word filed properly away, yep, okay, got it. “Fuck me, please,” she says, smiling, pleased at herself, look, I’m using it right. “Really hard.”
And Bellamy’s definitely going to hell for this already, so his whole body just says, to hell with it.
“Yeah?” he whispers, leaning down, cradling his sister’s face as his dick pumps in, out, in, out. “Yeah? You like it when I fuck you?” She nods, biting her lip. “Tell me, O. Tell me how you like it.”
“Fuck me harder,” she whispers, the perfect mix of innocent and dirty, eyes full of love, lips whispering his darkest desire. “Fuck me, Bell.”
“Oh God, O,” he groans, hips crashing into her, hard, fast, sharp, and she’s giving it right back. He’s never seen her this happy about anything. She’s never wanted anything this much.
He tries to pace himself, wants her to come at least one more time before he does, wants her first time to be perfect. Grits his teeth, holds on for dear life. But she’s so good, and he can’t hold back.
“O, I’m gonna -” he pants.
“Me too,” she gasps back. “Pretty soon, I think.”
“Can I do it inside you? It might feel ... kinda strange.”
“I wanna feel it.”
“Sure?”
“Yeah.”
“Okay,” he grits out. Teeth clenched, breath raw. So close. Almost there. Hands reach up to clutch his face, fingers soft on his cheekbones. Insistent. Pay attention to me.
“Look at me,” she orders him. “I wanna watch you.”
“Jesus, O – “ Swelling and swelling, so fucking close, oh God, he’s gonna lose it, her voice is gonna tip him over the edge.
“I like the way you look at me,” she says. “Open your eyes, Bell, look at me.”
So he does.
Pulls back up enough to see her, really see her, take in her whole face. She’s biting her lip, orgasm so close, so goddamn close, and the fingers that have been teasing her little breasts slide up to clutch at her face, her sweaty hair.
“I love you, I love you, I love you,” he groans. “Fuck, O. I love you. I love you.”
“I love you Bell,” she whispers back, eyes wide. “Thank you. Thank you for this. Thank you.”
“O – “
“I like you inside me, I like it so much, I want to do it forever – “
“O, I’m gonna come, okay? Hold on, I’m there, I’m there, I’m gonna – “
“Fuck me, Bell, please, I’m just, I’m like an inch away, I can feel it, fuck me – “
“Say it again, say it again and I’ll be right there – “
“Fuck me.”
“Say it again.”
“Please, Bell, please, oh, please, fuck me, please,” and then it hits them like an avalanche, like a ceiling caving in, almost exactly the same time.
He comes forever, spurting hot and furious inside her while she looks up at him, sweating and shaking. Her own orgasm ripples through her in wild little cries, all she can say is “Please, please,” and even though he knows it’s close to too much he can’t resist fumbling for her sticky clit as his soft dick slides out of her with a wet little rush. She squeaks at the touch, sensitive, but she doesn’t say no, and another orgasm bubbles up fast and sharp as he smears her cum and his cum together in a hot liquid mess all over her cunt. “Bell, oh, Bell, oh, that’s, oh,” but she can’t form a real sentence. But he understands her, nobody else understands her like he does, he reads exactly what she wants, she wants it to not be over yet, and so even though her body can’t take much more he stays right where he is, dick hot and soft against her belly, eyes on hers, fucking her with his hand until her fourth orgasm of the night is finally too much for her and she wriggles away.
Then, finally, he lets go.
His body drops heavily onto hers. She sinks down beneath it. They’ve never been this goddamn exhausted. Every muscle feels made of liquid. Can’t move. Can’t speak. Can hardly breathe.
They both fall asleep in moments, teeth unbrushed, all the lights still on, they weren’t even a little bit ready for bed. Bellamy dozes heavily on her chest. Total contentment. He drifts back awake at some point, doesn’t know when – middle of the night, lights went off automatically – and lifts himself gently off Octavla’s drowsy form. Goes to the bathroom, comes back with a warm wet rag. Tends to her sweet little body like a sacred thing, cleans off the sticky cum in gentle strokes, following it with kisses, reverent tongue on skin. Beloved. Cherished. Adored.
She opens her eyes, watches him, but doesn’t stir. “Hey,” she says softly.
“Hey. I wake you up?”
“S’okay.” Voice thick with sleep, a little dreamy. She lets him wash her clean, then watches as he washes himself in front of her. Doesn’t move or get up. He puts the wash rag back and climbs back into bed beside her. She settles easily into his arms.
“Never,” he starts off, voice cracking a little. “O. Never, in my whole life – it’s never – I didn't even know - “
“Love you too,” she says, and in moments she’s asleep again, safe in his arms.
