Furanui had no idea what Karurusu had been planning when he took him to his greenhouse. All he said was that he had been raising a special plant in secret in there. He hadn't even allowed any servants to go in there. Only Karurusu had been allowed within it. So, whatever it was, he was clearly dedicated. And that, along with the secrecy, made Furanui curious.
Karurusu was the type to switch hobbies very often. However, before those switches would happen, he'd still be pretty well-focused on whatever he was into at the time. And it often led to Karurusu doing something related to those hobbies for or with Furanui at some point. So, whatever it was about gardening that had caught Karurusu's attention, Furanui was sure it would end up at a result worth seeing.
However, Karurusu's insistence on keeping it all hidden from everyone up until now was quite unusual. Normally, he wouldn't hesitate to talk about his new interests, sharing them even more with Furanui than with others. But he had one day just decided to get a greenhouse for himself within the palace grounds and barely ever talked about it to anyone. But he had been taking care of whatever was in there, given he'd been seen going there every day.
When they walked in, Furanui could tell his efforts had paid off. The greenhouse was full of a variety of plants, big and small, of all kinds of colors, all very well cared for and beautiful. Furanui couldn't help but smile, proud of his brother for achieving such results.
So focused on admiring his surroundings, he was startled when Karurusu jumped at him and immediately wrapped his arms around his neck, their faces now so close that Furanui's cheeks immediately turned red.
"Do you like it?" Karurusu asked with a sparkle in his eyes.
Recovering from the momentary shyness, Furanui smiled and nodded. "I'm quite impressed. If anything, I think it's a shame you didn't let anyone else in here before."
Karurusu's smile widened, and he then quickly closed the gap between them as he kissed Furanui's lips. Caught off guard once again, Furanui almost lost his balance. But he was quick to recompose himself and wrap his own arms around his brother as he kissed him back.
Karurusu was quick to make the kiss more intense after Furanui's shock was over. Furanui didn't question it much. Given how energetic he was, it wasn't uncommon for Karurusu to jump at him and start making out with him just to spend some of that energy.
What did surprise Furanui, was when he suddenly felt something wrapping itself around his torso.
He jumped. Or rather, tried to jump, but whatever it was that had gotten a hold of him wasn't going to let go any time soon.
He looked down, and saw it looked like... A very thick vine?
He looked up to Karurusu, who was giggling to himself as this all happened. "Brother, what is this?"
"It's a surprise I made!" Karurusu spun a finger in the air, and immediately another vine came close, a bit too close to Furanui's face.
Its tip wasn't tapered like he thought it would be. Instead, its thickness was consistent throughout its whole length. On its tip, he could barely see a small dot. A hole?
"They're very easy to control with magic. I barely have to do much. They're pretty special."
Furanui eyed the vine that was close to his face suspisciously. "Is there any reason why you chose to raise these?"
"Well..." Karurusu smirked before moving his hand again.
The vine that was close to his face quickly forced itself into Furanui's mouth, reaching deep into his throat as it began to thrust. Before Furanui could even try to pull it away, three more vines showed up. One held both of his wrists above his head, while the other two grabbed his ankles and pulled them off the ground.
He was suspended in the air, legs spread as a vine fucked his mouth non-stop.
Karurusu giggled, and more vines approached him, this time with the mission of taking his clothes off. They got ripped in the process, but his nipples, cock and ass had been fully exposed. One smaller vine began to rub circles on one of his nipples, while another wrapped itself around his cock and started to pump it. Furanui couldn't help but moan.
With some effort, Furanui managed to open one eye to look at Karurusu. He was smirking, his were cheeks red, and there was very clearly an erection under his pants.
Furanui suddenly felt another vine touching him, and he instinctively closed his eyes and gasped around the one in his mouth. The new vine felt slimier than the others, and it was poking his asshole. Teasing but not pushing in quite yet.
"You look so good like this, Furanui." Karurusu said. And then, the slimey vine pushed in.
It reached as deep as it could within Furanui, before beginning to thrust in and out of him. He threw his head back, the sounds he made muffled. Being assaulted in that many ways was starting to get overwhelming...
Karurusu licked his lips, then pulled down his pants and underwear just enough for his cock to be out. He started to lazily pump himself, enjoying the show the vines were making out of Furanui.
Furanui let out a loud and long moan, no longer being able to hold back his orgasm as his eyes shut thightly. His cum spilled onto the floor, just barely missing Karurusu's shoe.
Before he could even go back to thinking properly, he whined as he felt (and tasted) some kind of liquid being spilled inside of him from the vines. It wasn't exactly like cum, being a little less dense and the taste being much sweeter (but not sweet enough to make him feel it was too much).
The vines that were inside of him pulled away, but he was still being suspended by the other ones. At least, he could take a moment to breath properly.
Karurusu giggled, and then hopped closer to Furanui. He cupped his younger brother's cheeks and didn't hesitate to pull him into a messy and wet kiss. Furanui was taken back by it, but reciprocated regardless. The kiss didn't last that long, but he couldn't help but feel some relief to have Karurusu close to him again.
"Hey, Furanui," Karurusu spoke as his fingertips brushed against Furanui's cock, "can you change this for me?"
Furanui didn't need anything else to understand what he meant. He bit his lip and looked away, but still began the process of using his magic to alter his body. It wasn't that he didn't like doing things differently sometimes, but rather that he knew he was going to be more of a wreck than usual now regardless of what his brother was planning.
The change didn't take long to be complete. Where his cock used to be, there was now a soaking wet pussy.
"Good boy~." Karurusu kissed his lips again as he removed his own pants and underwear. The praise made Furanui's face burn from ear to ear, but he couldn't deny the way his pussy squeezed around nothing.
Karurusu broke the kiss and lined his cock up with his brother's pussy. He slipped in easily with how wet he was, both of them moaning at the feeling.
Firmly gripping Furanui's hips, Karurusu began to thrust at a fast pace. Furanui threw his head back as he moaned louder. He felt embarrassed at himself for being in such a state already, just from a single round with those vines, but at least the pleasure from his brother's cock was enough to make him momentarily forget that embarrassment.
He was surprised by a vine showing up in front of his face again, barely wasting a second before filling his mouth with its length. Like before, there was nothing he could do about it aside from willingly suck onto it or move his tongue against it.
Karurusu giggled with a blissful sigh, then leaned in to bring his lips to Furanui's neck. He kissed and licked at a spot where there was an obvious bulge from the vine, which just made Furanui squeeze even harder around his cock.
Another vine pushed its way inside Furanui's ass. At the same time, he heard Karurusu moan.
Furanui tried his best to change his vision's angle, and he managed to do so just enough to figure out the reason for his brother's noises: there was yet another vine fucking into Karurusu's ass. Oh, that explained why Karurusu was moaning so sweetly.
But those moans didn't remain so loud for too much longer. Another vine showed up, and he happily took it into his mouth. Furanui could see a clear bulge on his throat as well. Surprisingly, Karurusu's thrusts hadn't faltered even once.
Furanui had thought that was as far as they would go, since there weren't really any more holes left to be used. But then...
He started to feel another vine try to push its way into his pussy, where Karurusu was still fucking him.
The vine managed to go inside of him, which made him throw his head back as he moaned around the vine in his mouth. He could barely think properly at that point. It was a pretty thick vine, too. So much that he didn't even need to look to know there was a bulge in his stomach from having both it and his brother inside of him. Just feeling it was enough... He had never been so full before.
Karurusu seemed to notice how it had affected him, fastening the pace of his thrusts even more. One of his hands let go of Furanui's hips to instead start rubbing his clit. Any clear thought in Furanui's mind was long gone at that point, now just a moaning mess as a certain feeling in his stomach grew once again with the build-up of arousal.
His whole body trembled when he came, his back arching and his walls squeezing the vines and his brother's cock inside of him even more. The vine in his mouth pulled out, making his loud moan completely audible to Karurusu.
Karurusu gasped, his usual big smile still on his face as he gave him a few more deep thrusts before he came. The vines "came" too right after, the one that had removed itself from Furanui's mouth now in a position that made its liquid spill onto both of their faces.
Furanui's mind blanked for a moment, trying to recover from the intense sensations.
Karurusu, having caught his breath a lot quicker, cupped his cheeks and pressed their foreheads together, softly looking into his brother's eyes. He giggled at the sight of Furanui being so spaced out, proceeding to give him a soft kiss on his lips.
Furanui was slowly starting to think straight again, and simpy kissed back just as softly. There was no urgency from either of them, both just enjoying the quiet moment and each other's lips.
After a few minutes, Karurusu stood up. He wrapped his arms around Furanui so that he would stop him from falling when the vines let him go and retreated. He easily lifted his brother, carrying him over to one of the benches with soft seating of the greenhouse.
Furanui felt a bit weird, with his holes now completely empty. But at least, he could still rub his face against Karurusu's neck and hold onto him tightly.
"Did you like my surprise?" Karurusu asked.
Furanui's only response was to hold him tighter and look down as his cheeks burned. He could admit to himself that he did enjoy it, but saying so out loud... It was too much! Too embarrassing!
However, that seemed to be enough for Karurusu. He giggled. "These vines are supposed to stay alive for about a year! So we can do this again sometime!"
Furanui's cheeks burned even more, unable to hide how he choked on nothing after hearing that.
But... He wouldn't be opposed to doing it again...
