Shouto rubs his hands against Natsuo's neck, palms rubbing warmth into his cold skin, smiling down at his brother's flushed face.
"It's not that cold."
"It definitely is that fucking cold!" Natsuo says through gritted teeth, his hands under Shouto's shirt pinching his stomach.
"Nii-san!" Shouto hisses.
"Keep going," Natsuo tells him, his cold fingers trailing up Shouto's stomach, poking and pinching his nipples.
Shouto blows hot air onto his face, and Natsuo closes his eyes, sighing happily. His flushed cheeks stretch up with a satisfied smile, and he rubs soothing fingers over Shouto's nipples.
"Thank you, baby," he murmurs in the cold space between their faces, his breath coming out foggy.
"You're welcome." Shouto wiggles his hips, and the deep groan that comes out of Natsuo's throat makes him grin.
He does it again, lifting himself up a little and going back down, his brother's thick cock dragging along his walls as he slowly starts riding him.
Natsuo keeps his hands under Shouto's shirt on his chest, grabbing at his breasts like they're handles for him to hold onto as he throws his head over the back of the couch and moans Shouto's name.
After that, warm and comfortable and close, it doesn't take him long to fill Shouto up.
Shouto continues to ride him through his orgasm, milking him of all his warm cum, moaning softly as Natsuo plays with his sensitive nipples as a reward.
"Good boy," he mumbles, eyes squeezed shut as he focuses on finishing and filling Shouto up. "Good boy, Sho-chan."
"Natsuo-nii," Shouto whines, sitting back down on Natsuo's lap as his legs give out under him, his head falling forward on his broad chest.
One of Natsuo's hands leave his chest, brushing over his side and ending up on his back, his strong, warmed up fingers rubbing soothingly over Shouto's shoulder blades.
"You did so good, Sho-chan. So good. Taking me so well, making me come, keeping me warm." He presses loving kisses on Shouto's hair and temple, his lips soft and adoring.
"Nii-san, please nii-san, can I? Can I come?" Shouto whines in his neck, shaking and shivering on his lap. He's so close, so close, just need a push. "Please please please!"
Natsuo thrusts up into him, his strong thighs lifting both of them up and down, and Shouto moans.
"Go on, pretty baby, come for me." His voice is fond as he whispers into Shouto's ear, and Shouto whines again.
"Please, nii-san!"
Natsuo hums, questioning, his hands never stopping their movement on Shouto's back and chest as he thrusts up again.
"Ah." Shouto digs his fingers in his brother's hips, whining and clenching around him. "Natsuo-nii, touch, please."
"Hmm? You want me to touch you? Aren't I already?" Natsuo huffs a laugh, amused by his own joke, but one of his hands finally trails down to Shouto's straining cock.
He doesn't even have to stroke him, just wrapping his warm fingers around him has Shouto coming so hard he sees stars, moaning loudly and shaking as he ruins his brother's shirt.
"Thank you thank you thank you thank you," he babbles against Natsuo's neck, feeling so high from his orgasm.
They sit there for a long moment, just holding each other on Natsuo's couch, breathing heavily as they come down from their high.
He pulls back a little, looking down at his big brother's blissful expression, and smiles happily. He leans to the side to grab the blanket they banished to the floor for limiting their movements and puts it around Natsuo again, huffing and puffing at him to move so Shouto can get it behind him and wrap him in it.
"You really need to fix the heater," he nags at him when he's done cocooning him in the blanket.
"Do I?" Natsuo grins at him. "Why do I have you then?"
"I'm not your heater!" Shouto smacks his chest, annoyed. "And I'm not always around e-"
He cuts off when Natsuo thrusts up into him, his cock still hard and full inside Shouto as he drills into him.
Shouto cries out, falling on Natsuo's chest again as he loses his balance.
"Nii-san!" He snaps at him, smacking his arm.
He feels Natsuo's thighs move under him, preparing for another thrust, and he digs into his hips.
"I'll ice you!" He threatens, and Natsuo immediately stops, his thighs going soft.
"Asshole," Shouto mutters. Natsuo's chest vibrates under his head.
He leans back to stare at him, and can't help but smile when he finds Natsuo grinning. It has become such a regular sight for him lately, seeing his brother smile, seeing him happy. Seeing him at all, actually.
It's nice. Shouto likes it. Likes seeing him smile because of Shouto, happy because of him. Likes that he can see him whenever he wants now, likes knowing that Natsuo wants to see him too, that he wants to have Shouto around all the time.
He likes how they didn't drift apart after everything; the war, their family's history, Touya-nii, Natsuo cutting their father off.
"What are you thinking about, huh? What is making your pretty eyes sparkle like that?" Natsuo asks, his hands coming to rest on Shouto's waist, squeezing.
"I'm happy that I texted you that night, after we visited Touya-nii that first time," Shouto tells him.
"Yeah?" Natsuo smiles, his eyes crinkling slightly.
"Yeah. And I'm happy you texted back. I'm happy you invited me to your dorm room and fucked me stupid on your bed."
"You're welcome, baby."
They laugh, happy. So so happy. And warm and comfortable and close.
Shouto lifts his hand to run warm fingers through Natsuo's hair, and he loves the way he sighs happily and just lets Shouto do whatever he wants.
"Can I ask you something?"
"Hmm?" Natsuo hums, his grey eyes focusing on Shouto's.
"What happened to your hair?" He points at the hair at his temples. "I don't remember ever seeing it like that, but Fuyumi-nee told me you used to have some red here."
Natsuo is quiet for a moment, and Shouto wonders if he overstepped. If he got too comfortable too quickly. They've only gotten close for barely a year after all.
"I dye it." His voice is weird when he answers. "I still have the red, but I always dye it."
"Oh." Shouto isn't sure what to say to that. "Is... is it because... cause you hate... him and everything that has to do with him?"
Natsuo doesn't say anything to that, and Shouto feels something squeeze tight in his chest.
"Do you... does that mean you hate... hate me too? Cause I have red hair? And his eye? And..." he trails off, biting his lip to keep from crying right there on Natsuo's lap with his brother's cock still filling him up.
And he wants to get off of him, wants to get up and run away and never have to think about how Natsuo must feel the exact same way their mom did when looking at Shouto.
Natsuo grabs his chin, and lifts his head up, and Shouto hadn't even noticed that he was looking down to escape his eyes.
"Sho-chan, will you look at me." Shouto shakes his head, still looking down. "Baby, please."
His eyes are soft when Shouto looks up, and something in them hurts; for himself? For Shouto? For both of them? Shouto doesn't know.
"I don't dye my hair because of him." He starts slowly, and then stops, shaking his head. "Well, I think I sort of do, but not..." he trails off, and this time he's the one who looks away. "After mom... hurt you, I didn't go see her for a while. A couple of years I think. Because I was young and they didn't let kids in the hospital, and because..."
Shouto has a feeling he knows where this is going, and he wants to scream and cry and sob that it's not fair it's not fair it's not fair why did it happen to us why why why WHY but he knows that would just make his brother close off and stop talking, so he just rubs his hips soothingly and listens.
"I was scared, that she would... see him in me and hurt me too," he whispers that last part and Shouto wants to rip his own heart out and give it to him; I'm here, look at me, I'm here I'm yours I love you I'm here he wants to tell him over and over, until their scars stop bleeding and their hearts feel whole again.
"Fuyumi helped me dye my hair when I was 13, and then she took me to see mom for the first time in years, and she was... she was just a broken woman. Cold and awkward and distant. It didn't feel like she could hurt anyone. But I... I don't know." He shrugs, his fingers tapping on Shouto's waist, eyes staring to the side. "I guess I was just scared of triggering her, and then I had been doing it for years and it just felt natural to have all white hair."
They're both silent for a while after that, and Shouto curses himself for asking. He wraps his arms around Natsuo's shoulders and hugs him close, shoves his head in his own neck and kisses where the red in his hair would be.
"I love you," he whispers in the quiet settling between them, says it so he doesn't bleed I'm sorrys all over the room, because that's not what Natsuo needs. If he needed apologies he would've heard their father out.
He kisses his hair again and tells him again, louder this time, hopes it sounds as soft as he means for it to be.
"I love you too, Sho-chan," Natsuo breathes against his collarbone, his warm breath tickling Shouto. "Pretty baby. Kind. You're so kind." He presses gentle kisses on his chest in turn for the ones Shouto plants on his hair, and they kiss each other until they're both giggling, shaking with their happiness and falling on their sides on the couch, facing each other.
Warm and comfortable and close.
