Karurusu had tried many times to make Furanui dress up for him. He always said he thought Furanui would look good in a maid outfit, or in lingerie, or in a bunny outfit, or a nurse... Really anything Karurusu could think of.

But Furanui always refused time and time again out of embarrassment. Karurusu would pout, but he'd never push him to do something he didn't want to.

But then their anniversary was coming around. And Furanui wanted to do something special for it. Something to celebrate the date when they had become more honest about their feelings for each other, when they had become closer than ever...

And so he figured that finally giving in to Karurusu's fantasies wouldn't be so bad. It still made him feel a bit embarrassed, but he tried to swallow his pride for once.

He dressed himself in one of those sexy bunny outfits Karurusu had suggested to him once. The red one piece directly against him made him feel flustered the moment he put it on.

He had used his magic to give himself bunny ears and a puffy bunny tail, color matching his hair. The extra pair of ears on his head and the enhanced hearing felt odd, but he expected he'd either get used to or end up too... distracted to keep on noticing it.

He waited for Karurusu in his bedroom, already hot and bothered from antecipation alone. Thanks to the enhanced hearing, he could tell when Karurusu was getting closer. He was humming, and apparently hopping as he walked.

Karurusu entered the bedroom without even knocking. He opened his mouth as if to say something, but was quiet for a moment when he saw Furanui.

And then, once he had processed what was in front of him, his lips turned into the widest smile Furanui had ever seen on his face. His cheeks were red as he squealed.

"You look so good!" Karurusu said as he walked up to the bed. He crawled on it so he could sit up in front of Furanui. "You did this for me?"

Furanui only nodded. He was still a bit too embarrassed to form words.

Karurusu immediately lunged forward to wrap his arms around him and crash their lips together. Furanui was caught off guard, but Karurusu simply used that to his advantage as he pushed him down, immediately taking control.

Their lips parted and Karurusu sat up, straddling Furanui's legs. His face was one of utter adoration as he looked Furanui up and down. It made Furanui feel like he had butterflies in his stomach.

Karurusu brought the tips of his fingers to Furanui's shoulders. He slowly moved his hands down, in a wavy motion as he felt for every inch of his brother's torso.

When he reached his hips, one of his hands kept moving down towards Furanui's thigh. But the other one went for his crotch instead, at a much slower pace.

He squeezed Furanui's thigh. "You did this to surprise me, didn't you?"

Furanui couldn't bring himself to speak, for he feared he'd let out the gasps he was trying so hard to hold back. So he just nodded instead.

"I'm so happy!" Karurusu smiled, his other hand stopping at Furanui's clothed cock.

When he began caressing it in an up and down motion, Furanui moaned. The sound made Karurusu's smile widen.

Karurusu pushed the red cloth of the outfit to the side, allowing Furanui's cock to spring free. The way he licked his lips made Furanui's face burn, but he couldn't say he disliked it.

Karurusu leaned forward in order to kiss his lips. As he did so, he took Furanui's cock into his hand and pumped it slowly.

He moved forward a bit, just enough for his hips to hover over Furanui's. He broke their kiss, looking into his brother's eyes. "Furanui, I wanted to surprise you as well." He let go of his cock and snapped his fingers, making his own clothes disappear.

At first, Furanui couldn't quite tell what he meant by that. Karurusu had opened his legs, a hand reaching back to finger himself. His whines were very clear, and Furanui's bunny ears made it so he could also clearly hear wet noises.

Karurusu pulled out his fingers, and then positioned himself so he could guide his cock inside. When he lowered himself, Furanui understood what his "surprise" was.

It was a lubing spell.

It was a fairly complicated spell. Not impossible, but it still required quite a bit of practice to get right. So that meant... Karurusu must have spent quite a while fingering himself in order to be so slick.

The way Karurusu rolled his hips, along with that mental image, made Furanui throw his head back into the pillow and moan.

Karurusu bounced once and chuckled. "Do you like it?"

Furanui bit his lip, eyes closed shut, and nodded.

Then, Karurusu grabbed his wrists and held them above Furanui's head. When his hands left, Furanui couldn't move his wrists anymore, being held to the headboard by magic golden chains.

"H-hey!" Furanui attempted to argue, but immediately bit his lip when Karurusu started bouncing at a steady pace.

"Just relax, okay?" Karurusu said with a soft smile. "You've been taking the lead a lot lately. So let me take care of you for tonight." He rolled his hips as he pushed down, and moaned.

Karurusu was right. For the past month, all the times they had decided to fuck, Furanui was the one being dominant. And while he did enjoy that a lot, he did also like having Karurusu take that role instead from time to time. And he was happy to know Karurusu enjoyed it as well.

Karurusu moved his hips faster, his moans constant as Furanui panted. It was already normal for him to get very affected by Karurusu's noises, but his enhanced hearing made them even more effective. He couldn't help but thrust up at times, earning pleasured gasps from Karurusu in return.

"Furanui~!" He moaned, changing his angle just enough to make Furanui's mind almost go blank. "I love you~! Give it to me~."

Unable to hold himself back anymore, Furanui shut his eyes and moaned. His hips moved on their own, thrusting up and shooting his cum inside Karurusu, who gleefuly moaned as he milked every last drop of cum from his brother's cock.

Furanui panted for a good few minutes. Once he had caught his breath, Karurusu pulled him out, gasping at the feeling of emptiness and of some cum oozing out of his hole.

Furanui opened his eyes. Karurusu still seemed to have plenty of stamina left. And when he looked down, his cock was hard and erect. When Furanui took a moment to think about it, he realized Karurusu hadn't touched himself at all this whole time...

Karurusu pushed Furanui's left thigh up. He caressed it, played with the hem of the thigh-high see-through black stockings of his outfit, kissed his knee, overall just showering him with affection that made Furanui's face burn.

And then, his hand moved lower. Until he reached Furanui's entrance. He nibbled on his thigh as he circled and prodded his asshole, and that alone made Furanui gasp.

Karurusu closed his eyes, concentrating. And when he pushed it inside, his finger felt slicky.

Furanui bit his lip. He had read that, if done correctly, the spell also felt more pleasurable than normal fingering. The fact that Karurusu knew exactly how to push his buttons wasn't making it any easier for him to hold back noises.

"It's okay, Furanui." He pushed a second finger in, thrusting a little faster. "I want to hear you."

Furanui allowed himself to gasp, which turned into a moan when Karurusu bit his thigh.

After a few more minutes, during which Karurusu had spread multiple bite marks through Furanui's thigh, he pulled his fingers away. He gave him one last kiss on his knee, and then positioned himself so the tip of his cock was brushing against Furanui's hole.

He pushed in, making Furanui moan and throw his head back as he became completely full with his cock.

Karurusu thrusted slowly a few times, but didn't take long to pick up his pace. He placed his forearms on each side of Furanui's head, leaning over with his face just a few centimeters away from his.

Furanui was so overwhelmed by his thrusts that he could barely pay attention to whatever nonsense Karurusu was saying in the heat of the moment. He mumbled about how tight he was, how good he felt, how much he loved Furanui, how good he looked, how happy he was. All of that mixed in with moans from the both of them.

Karurusu chuckled. Then, he kissed Furanui passionately as his hips snapped forward even harder.

Right as his thrusts became more erratic broke the kiss. But his eyes scanned every feature of Furanui's face, not wanting to miss any change in his expression.

Furanui's eyes rolled back as he came inside of him. He cursed as he arched his back, too overwhelmed by the sensation of being filled up.

Karurusu also looked knocked out. His mouth hanged open, tongue sticking out, and he had a dazed look in his eyes.

Furanui couldn't help but smile at that. He cupped Karurusu's cheek, caressing it lightly with his thumb.

Karurusu put his hand over Furanui's, closing his eyes as he leaned into his touch. When he pulled out of him, Furanui gasped.

But after that, Karurusu just laid down on top of him. Furanui ran his fingers through his hair, blushing at the fact that he could feel Karurusu's breathing against his own chest. They were almost perfectly in sync.

Furanui was so relaxed and distracted by that calm moment that he was taken by surprise when he felt Karurusu's hand scratching the back of one of his bunny ears. Karurusu giggling at his reaction just made him blush more.

"You're so cute, Furanui!" Karurusu whispered into said bunny ear.

"Shut it!" Furanui moved away from his grip.

However, Karurusu simply cupped his cheeks to hold him in place as he kissed his lips. A soft and chaste kiss. And suddenly, Furanui didn't want to argue with him anymore.

He was simply glad he had made Karurusu happy.
