Work Text:
Vash and Nai have always been inquisitive. Though one more so than the other, it doesn't stop them from taking an equal interest in each other's bodies. While they're practically identical, they both agree that exploring one another is more exciting and rewarding than exploring themselves alone.
And that's how they ended up here with Nai eating Vash out hardily in their shared bedroom.
Their genitals are much different from humans.. while they do have what looks like vulvas, it looks extremely flower-like with the entrance in the center and what looks like little red stamens protruding from the center.
However, they are more flesh-like than plants, they move and squirm and wither around, smearing juices all over the older twin's face as he tries to gather them all into his mouth.
Once he does he sucks on them and that gets him a high-pitched whine from his brother. The walls are not exactly thin..but if they're loud enough someone will certainly hear them. His very much expressive brother used to be anxious over this, but with enough reassurance that no one will hear, he lets himself go.
Vash moans as his brother works hard to keep them in his mouth and suckle on the little tendrils, making them produce more fluids.
Eventually, Vash whines "Nai~ don't just suck on them, put it inside!"
Nai furrows his brows, trying to work his finger inside while not letting the tendrils slip out, but Vash stomps his foot on the bed, "no no! Not your fingers you're- " he's then cut off and gasps as his older twin shoves his tongue into him. He ends up breathlessly gasping out "yes yes! Just like that-'' he tries to buck further onto his brothers tongue "- like that it feels soo goood."
Nai tries to pleasure his brother the best he could but the tendrils end up slipping out of his mouth. Not that Vash seems to mind though, he seems far more enjoys having something inside of him.
Vash is reduced to moans and whimpers, and eventually, a worried voice is heard outside their door.
"Vash? Nai? Are you guys okay?"
It's Rem.
Vash lets out a squeak of fear and freezes in place. Nai, on the other hand, is only a bit surprised, though he really shouldn't be. Of course, Rem would eventually hear them at some point. He just didn't care. He wanted to hear his lovely brother's voice.
Nai recovers quickly, but before he can reassure her everything is alright, she opens the door at Vash's suspicious squeak. "Just what are you guys u-" her voice dies at the scene before her. Nai's first instinct is to cover Vash up, but she still catches something pink and red between Vash's legs as he makes a scared little noise and scutters to hide under the covers before Nai can react. The pants and underwear left off to the side of the bed is telling, and so is the slick smeared on the older twin's face.
Nai didn't expect her to just walk in like that, but soon the shock wears off and is replaced with anger. "GET OUT!!" He screams as he grabs a pillow and throws it at her. She flinches and closes the door before the pillow hits her. She hears him continue yelling, "Don't you know how to knock?!"
She quickly walks away as she tries to process what she has just witnessed. They were.. but they're brothers.. so they shouldn't.. but what if..? She shakes her head, she has some things to do and she'll talk with them later.
Back in the room, after spending some time calming down, Nai gets under cover with Vash and gets between his legs again, but Vash pushes him away. "No Nai, I'm not in the mood anymore." He's honestly too mortified to.
But Nai stares up at him from under the covers huffing irritably. It makes Vash feel a little guilty, and he looks away from his brother's gaze.
"Fine, then you help me." Nai gets up and shuffles forward, so his legs brackets Vash's head. Like this, Vash can clearly see the wet patch between his older twin's legs. Vash flushes a little bit, but this isn't something new. However, he *really* isn't feeling it.
But before he can protest again, he hears his brother call his name in a whine.
"Vash~"
It's just barely there. His brother usually isn't one to whine like that, so Vash guiltily relents.
"Fine." Vash hooks his thumbs under the hem of Nai's pants and underwear and tugs them down as his twin tries to step out of them. It's clumsy due to their positions, but they get it done.
Their genitals are practically identical, but Vash doesn't understand how his twin can have such deliberate control over the little tendrils. He wraps them around each other to make something bigger. Vash already knows what his brother wants from him and leans in.
____________________________________
Vash hesitates about going to dinner. He doesn't want to face Rem after being walked in on like that. He's too embarrassed. Nai reasons that if he doesn't want to go, then he shouldn't go. It's not like they need to eat anyway, so why be there for dinner? However, Vash would feel guilty if he didn't show up to eat with Rem. It's something nice they do together. Vash doesn't need to eat, but he enjoys it, and it's a nice way to spend time together. It feels special.
Nai sighs and rolls his eyes at Vash's dilemma. "Let's just go." He grabs Vash's hand and leads him to the dining room. Vash protests but ends up following along willingly.
Vash sits anxiously and awkwardly at the dining table. He avoids looking at Rem and continues to hold onto his brother's hand, even interlacing their hands together for comfort.
When Rem brings out a plate of food for both of them, Nai sighs. Though it's a smaller serving. Rem always insists on serving him since he always comes along with Vash for dinner. It's a moot point by now.
Vash looks like he's having a hard time looking excited as much as he tries to smile, and Rem also looks vaguely uncomfortable.
Once everyone has been severed and seated, there's an awkward silence as everyone..*tries* to eat.
Eventually, Rem breaks the silence
"There's something important I need to say.. About what I saw earlier.."
Vash tenses up, and the grip on Nai's hand tightens. He still can't look up at her. Nai returns it reassuringly and looks straight at her. His cheeks still flush a little bit at the topic, but it looks like Vash won't be speaking up anytime soon. "What about earlier?"
Rem hesitates a bit and ends up looking away briefly before looking back at them. "Siblings shouldn't be those sort of things together..and-" well, they may be a little too young for this to be possible. "-if you guys end up impregnating each other, that could cause huge issues. Plus, you guys are still so young.."
There's a stretch of silence before Nai says, "But we're plants, we aren't human. Even if that was a concern, couldn't we just.. avoid it?"
Rem sighs at this. While it's true, they could just avoid having sex that could result in a pregnancy, a lot of people say that and still wind-up pregnant regardless. She was more hoping that they'll take this reasoning as it is, and she wouldn't have to have a deeper and potentially more uncomfortable conversation with them..
But they're obviously smarter than that, especially Nai. Rem sighs once again, "It's just really isn't right.. brothers shouldn't be attracted to each other like that."
Gradually, Nai feels his brother's hand retreating from his.
She continues on, "and I don't want you guys to be taking advantage of each other. "
When Nai glances to look at Vash, he almost looks ashamed as he stares down at his plate. It makes something inside him boil. His grip on Vash's hand tightens, and he pulls it towards him to rest on his lap. It makes Vash turn his attention to the twin, and he sees the expression of anger on his face. Sharp and quick Nai adds, "None of that makes any sense! We're not hurting or taking advantage of each other, so what's so wrong with it?! "
Vash scoots closer to Nai, so they're touching hip to hip. Gently and softly, he speaks in an effort to soothe his older twin. "Nai, don't be so angry.." when that doesn't work, he leans his head onto his shoulder and asks pleadingly, "please?"
Nai calms down but not before saying "tch, this is ridiculous."
Rem doesn't say anything further, she just closes her eyes and pinches the bridge of her nose. "You know what, let's just talk about this later." She had no idea how she was gonna get her point across. She notes however that Vash has been pretty quiet this whole time, so she wants to talk to him when she gets the chance.
They continue with their dinner in silence. Vash barely eats and as always, Nai barely touches his food. They part their separate ways after dinner but the twins hardly part from each other, so she asks Vash to help her with something to get him alone.
At some point along their task she asks "Vash, Nai doesn't force you into anything, does he?" A blush rises on his cheeks and shakes his head. "No, never." After all, he always agreed and said yes to whatever Nai wanted. He was always so weak for his brother..
"If you say so.." she says in a dubious tone as if she doesn't quite believe him. She makes a mental note that it might be time to get them separate rooms. "If anything happens you can always come to me okay?" Vash doubts anything will but it's a sweet sentiment. He smiles and nods.
After Vash is done helping her, she comes across Nai. The boy approaches her a bit sheepishly and says a bit meekly without looking at her, "I don't think I'm wrong for what Vash and I do together but I'm sorry for yelling at you at dinner and for before too.."
Rem is a bit exasperated at the former statement but she'll take the apology. What else can she do? "It's fine Nai, and I shouldn't have walked in but all is forgiven, right? " she smiles and wraps her arm around Nai's shoulders while ruffling hair. He accepts it a bit reluctantly.
At the end of the day, the twins cuddle up in bed. Nai hugs Vash from behind and nestles into him humming contently. This isn't unusual. Maybe it's not always in this position, but they've always shared a bed and cuddled up together.
What *is* unusual is Nai's hand starting to caress him from chest to stomach, each pass reaching lower and lower past his navel. Vash has always welcomed the heat it makes him feel and what it leads to but this time it makes him tense up.
He grabs Nai's hand and stops it in his place, and it makes Nai stiffen up too, he can feel him against his back. It takes him a moment before he says, "Nai..I don't think we should be doing this anymore.."
...
"You can't be serious! Do you actually believe everything Rem says?"
When Vash turns towards his brother to argue, "but she's-!" He sees the hurt in his brother's eyes. It halts his words in its place and makes his breath catch in his throat. The pain in his twin's expression squeezes his heart and tears him up inside, and finds himself unable to continue his sentence.
Nai waits for him in silence until Vash sighs. "Nai..I'm sorry." He says it remorsefully and full of regret. He reaches out to cup his brother's cheek and Nai closes his eyes and presses into it. The action makes affection bloom in Vash's heart and makes him lean in to give his twin a kiss on the lips.
It's meant to be chaste but Nai eagerly returns it and soon enough Nai is on top of him making out with him..or at least doing his best to..This is all still relatively new to them. When they part for breath, Vash stares up at his brother who's all flushed and panting, and he can't help but think how beautiful he is.
He cups Nai's face again using both hands this time. He smiles at him and says sweetly, " I love you Nai."
Nai returns it with a smile of his own. "I love you too Vash." He leans down and kisses him sweetly before it quickly returns to being heated.
Rem's words are still in the back of Vash's head, but he can't deny that he absolutely enjoys his older twin brother like this, and for now he completely forgets about them.
