Trust Your Big Brother

Karls always found Furanui's blushing face to be quite cute. Seeing his younger brother, always so proper and composed, lose some of those walls of his was entertaining to him.

This situation, with both of them sitting on their big shared bed, was no exception. But the reason behind his embarrassment was different from usual.

"Y-you're using that!?" Furanui stuttered, pointing at the dildo in Karls' hand.

"What? Are you nervous?" Karls asked.

Furanui went silent and he looked away from him. Karls couldn't help but smile. If his little brother was so tense, it was his job to make him see there was nothing wrong.

He set the dildo aside for a moment before moving closer to Furanui. Close enough that their noses were only a few millimeters apart. Karls cupped both of his cheeks with his hands.

"I promise I'll make you feel good. You trust me, don't you?"

Furanui was quiet for a moment. But, as he looked into Karls' eyes, he took a deep breath and nodded.

Smiling, Karls kissed his lips. He felt how he relaxed through the kiss. Furanui's hands moved to Karls' waist, just holding onto him. He opened his mouth, allowing Karls' tongue to enter it.

Furanui gasped into the kiss, and the sound sent a shiver up Karls' spine. He always loved hearing those sounds of his so much.

When they separated their lips, Karls pushed Furanui lightly to make him lay down. He could still tell Furanui was slightly nervous, but it was nothing he couldn't solve. He always found a way to make him melt onto his touch.

Karls adjusted his position on top of him, sitting on his lap. After caressing Furanui's cheek for a moment, he began to slowly unbutton his blue pajama shirt. (He could just make his clothes disappear with magic, but they simply enjoyed taking them off themselves.)

Once his torso was fully exposed, Karls began kissing his body. Soft, quick kisses to his cheeks and jaw. Then rougher kisses and bites on his neck. Furanui groaned a little whenever he bit hard enough to leave marks.

He moved lower, spreading kisses through his chest. He nibbled on one of his nipples, using his hand to rub the other. This time, Furanui bit his lip to hold back a gasp. His hands went for Karls' hair, simply caressing and running his fingers through it. It made Karls smile as he held back a chuckle.

He kissed his nipple one last time before moving lower, reaching his stomach. Even the smallest touches there made Furanui's body react. Sometimes he felt a shiver. Sometimes he held back a giggle when Karls' touches tickled him. Karls always had to hold back an urge to actually make him laugh. As much as he liked making Furanui laugh, it usually ruined the mood of moments like this for Furanui.

Karls stopped kissing his stomach, looking up at him as his hands moved to the edges of his pants. He pulled them down, smirking as he could see how hard his brother was under his underwear.

He pulled his underwear down as well, and Furanui's blush deepened. And when Karls brushed his fingers on his cock, he gasped. Karls wrapped his hand around him and began pumping him. And it slowly became more and more difficult for Furanui to hold back any of his gasps. And Karls loved every single one of them.

He brought his lips to the tip of his cock, licking it and tasting the precum that had been leaking out of it. And when he took the whole head into his mouth, circling his tongue around it, Furanui groaned.

When a moan slipped out of his mouth, Karls pulled away. Furanui whined, but when Karls magically materialised a bottle of lube onto his hand, he went silent again.

Karls giggled. "Don't worry, I'll be gentle. I always am, right?"

Furanui took a moment to reply, his voice so quiet he was almost whispering. "Yes."

Karls hummed gleefully in response. He coated his fingers in lube, then brought them to Furanui's hole. He circled it teasingly. And when he did put a finger inside, there was an immediate groan from Furanui. Karls could see the way he clutched the sheets, the way his breathing hitched.

It was all wonderful.

He began thrusting his finger in and out of him. At first, the sensation made Furanui arch his back. But he settled back down when he got used to it.

It didn't last that long, though. When Karls put another finger in, he started gasping. The movements he made with his hand, along with the way he slowly spread his hole, was enough to make him bite his lip to hold back moans as well.

Once he was satisfied, Karls pulled out his fingers. He gave Furanui a chance to catch his breath before reaching for the dildo once again. He began spreading lube on it.

Even as he focused on that, he could tell Furanui was staring at him. So when he was done with the lube, he caressed one of his thighs. He was glad to feel him relax. Even with the lube, having his whole body so tense wouldn't do them much good.

Karls then pulled Furanui's legs apart, keeping his own body between them to make sure they stayed in place. "Your big bro will make you feel good~." He teased him with a smile.

Furanui didn't reply. He simply turned his face away and closed his eyes.

Slowly, Karls started slipping the dildo into his hole. Furanui gasped, but then immediately held himself back from making any other noises. Karls didn't feel all that bothered with that. At least not yet. He would get all the reactions he wanted from Furanui soon enough.

Once the dildo was fully inside of him, Furanui couldn't really hold back his moan. Karls left it still inside of him for a while, letting his body get used to it.

Once Furanui's body had relaxed, Karls flipped a switch at the base of the dildo. It began vibrating.

The sudden sensation almost made Furanui jump, making him moan loudly. And even when he covered up his mouth, it didn't really muffle him enough. Karls smirked at that.

He gave Furanui's collarbone a kiss as he caressed his thigh. He then moved back to start licking his cock again. He didn't take long to take his head back into his mouth, tasting even more precum than he had the previous time.

He lowered his mouth a little with every moan he heard from Furanui. Furanui brought his free hand to Karls' hair, pulling on it this time.

His grip on it tightened when Karls' lips reached the base of his cock, having his whole member in his mouth. Furanui moaned, the hand that had been covering his mouth slipping away. And Karls could feel his whole body relaxing as he gave up on trying to hold back.

He hummed joyfully around his cock. That, paired with the vibrations from the dildo inside of him, made Furanui moan his loudest moan yet.

Karls started moving his head, bobbing it up and down slowly. Pressing his tongue against him. In the state Furanui was in, he knew he wouldn't need to put in too much effort.

"Brother!" Furanui gasped. His hips trusting up instinctively.

Karls simply caressed his thigh reassuringly, humming.

"Fuck-!" Furanui cursed as he came. Karls moaned as he swallowed the warm liquid, and he loved that taste he knew so well.

Furanui let go of his hair, gasping as his body went limp. Karls pulled away from him, turning off the dildo and then pulling it out of him. He sat up, smiling at Furanui's seemingly exhausted form.

"See? Didn't I tell you?" He asked.

Furanui groaned and looked away from him. "Shut up." He mumbled.

Karls didn't reply to that. He simply put the dildo aside and crawled back on top of Furanui.

He gave him a chaste kiss to the lips. He intended to just lay down and rest, but Furanui seemed to have his own plans. Karls squealed in surprise when he switched their positions.

"We're not done." Furanui said, his hand very close to Karls' covered hard-on.

Karls didn't reply immediately, but then smirked. "Oh. Really?"

Furanui slowly undid Karls' clothes, and Karls couldn't help but smile every time Furanui touched his skin. He intentionally grinned up at him with half lidded eyes, knowing fully well that always made Furanui blush.

Furanui looked away from his face and sped up his hands, but then proceeded to blush even harder as he exposed Karls' fully erect cock. He hadn't even been touched all that much, but he couldn't help it when he just loved Furanui and his reactions so much.

Despite his blushing, Furanui didn't hesitate to lower his head and wrap his hand around Karls' cock. He licked and kissed the head, clearly a bit surprised when Karls' whole member twitched in response. Karls didn't even try to hold back his delighted gasp. Unlike Furanui, he felt no embarrassment in letting him hear just how good he was feeling.

Furanui took a deep breath, then took in all of Karls' cock in one go and began sucking him up and down. Karls threw his head back and moaned. "Furanui~. That's a good boy~."

Looking down once more, he caught a faint blush on Furanui's cheeks for a moment. It didn't matter how many times Karls had already said similar things to him in and out of the bedroom, the praise always seemed to sound like music to his ears. But Karls didn't mind saying it as many times as possible.

Karls thrust his hips up, making Furanui groan around his cock and he opened his eyes to glare at him. But he kept going anyway, increasing the speed in which he bobbed his head. Karls moaned again, his tongue sticking out of his mouth.

Karls had begun thrusting into his mouth again and again without thinking, constantly hitting the back of his throat. But Furanui didn't fight back, he had grown used to that sensation. He used one of his fingers to rub circles around Karls' hole, in an attempt to have more control of the situation. His other hand squeezed his thigh.

Karls' loved having Furanui's hands on him, no matter where he touched. So just that was enough to make him moan louder, his back arching as he came in Furanui's mouth. Despite a small groan at first, Furanui drank all of it.

When Furanui pulled away, Karls took a few deep breaths, then looked down at him. He smiled, cupping both of Furanui's cheeks. He hadn't expected anything in return for making his brother feel good, and yet Furanui did it anyway. How could he not feel nothing but love for him at that moment?

Once Furanui was on top of him, he immediately pulled him in for a kiss. There was still an aftertaste of his cum on Furanui's mouth, but that detail just made him enjoy the kiss even more.

When their lips separated, Karls hugged him, tightly holding onto him as he intertwined their legs. He brushed the tip of his nose against Furanui's, and his heart warmed when Furanui smiled at him.

"So? Didn't I tell you it'd feel good?" Karls asked with a smile on his face.

Furanui didn't reply, he simply blushed and looked away. Karls giggled and leaned his forehead on Furanui's shoulder. Furanui ran his fingers through Karls hair for a few minutes. And when he stopped, Karls noticed his breathing was steady and peaceful, so he could tell his younger brother had fallen asleep.

He smiled, hugging him tighter as he just appreciated the warmth of Furanui's body against his. He didn't really intend on sleeping, he just wanted to enjoy his body for a while longer.
