Warnings: Full on yaoi twincest.

The wind never stopped. The days were hot, the nights were cold, and the blowing was incessant. I had begun to hate my brother. I tried to forgive him, tried to see things his way, tried to love him, but it was pointless. I couldn't forget Rem, and whenever he sensed that I was thinking of her, he would get so angry. So I learned to be quiet, and to be patient, because without me, who would take care of him? Without him, who would take care of me? I lived off my love for my brother, and didn't notice when it began to sour, when my life became routine, and I had to seriously control myself, watch what I wanted to say. I didn't notice, because when you're living on love, you know that if that love ends, your life ends. I never wanted to hurt Knives, but I just didn't know if I could stay with him anymore, or at what point my love for him became self-mutilation.

As we drifted apart, I noticed that he tried harder to say kind things to me, tried not to say any of his colder thoughts, tried not to rant about his hatred for humans, tried not to say anything about Rem, but none of it seemed significant. He had to try to censor himself so we wouldn't fight, and I couldn't appreciate the effort because I had subconsciously given up. A long time passed like that, where I only followed because following was all I knew, I only stayed because I had convinced myself this love was all that I would ever have, my brother more a part of me than I was.

Then things began to change, or more-so, we began to change. I guess neither of us had realized we would age similar to humans, that we would "grow up", and since no other Plants had lived outside the glass before, we had no idea how quickly it would happen, or what it could possibly be like. Therefore, imagine awakening not as pubescent, but young adult, those awkward tweens gone before they could be analyzed.

Imagine taking a bath in one of the very few and far between oasis's, turning around to see your twin staring at you. I mean staring at you, as though there was anything on me different than on him. It was little stuff like that mostly. Waking up at night with Knives staring at me, play wrestling that ended up uncomfortable, accidentally touching my butt. That sort of stuff, so even though I didn't know what an infatuation was, or understand anything about physical love, Knives did, and he wanted me.

These incidences culminated, and finally, I don't think he could have stopped if he'd wanted to.

We'd been walking for hours, just walking. Somehow, Knives never got lost in the desert; I couldn't figure it out, he said it was because of our "Brother and Sister Plants", and he could feel where they were in relation to us. However, he had no way of knowing there was an enormous sand storm coming, and it was by sheerest luck that we were able to find a part of the wreckage to hide in.

As the sands began to lift and blow around us, we looked around frantically. We knew this planet ate things, and whatever we took shelter in had to be rather large, or we may be buried. All we managed to find was part of a hallway from a SEEDS ship, one end of it so mangled it wasn't open, the other conveniently facing a rock face. In our run, I fell, and smashed my knee into a rock. Knives didn't hesitate, he grabbed me up, and helped me along. On his face was the look of pure horror, and as we settled in, I realized it was fear of my blood. Not that he feared it could harm him, but I think a fear because I was harmed. That was proven in the way he began to squabble about me, and make such a fuss.

"It's just a busted knee Knives, I'll be perfectly fine."

"Are you sure Vash? You don't think you chipped the bone, do you? I think we should tourniquet off your leg, so you don't lose too much blood… What if you died from dehydration and blood loss? Don't look at me like that, we've barely had any water. We need to sterilize that somehow…"

I pulled my pant leg up, and blinked at the tiny abrasion on my knee. "No, really Knives, I'm totally fine. Don't worry about me." And I tried to give him a reassuring smile, but for some reason, he looked like he was going to cry.

"I just worry about you so much Vashu, you're the only thing I care about. Just me, and you, and being happy- I don't want you to ever get hurt. I don't know what I'd do if something happened to you…"

I cut him off, "Knives, really, I'm fine. Nothing is going to happen to me. I'm not hurt, we're just going to sit this storm out, and then we're back on our way, ok? Don't worry about me."

"I do worry about you though, I worry about the humans hurting you…"

"You're paranoid. You're manipulative. The humans on the ship never did anything to you, Steve only hurt the others because you made him! God Knives, I just can't stand you anymore, I hate you! You and this crazy stigma about humans! You already almost annihilated the species, what more do you want? You're nuts. I love you, but you're nuts."

It had been a long time in coming, and once I'd started I couldn't stop. When I was too exasperated to continue, I looked at my brother, to see if he'd heard me, if he'd realized just how much he had hurt me, just how horrible he'd been.

"Everything. I. Have done. Was. For you." Knives' face was hard, his eyes were distant, and his lips were a solemn line. I was quite suddenly terrified of my brother for the first time. I'd seen him mad before, but none of the jovial quality was here now. I wondered then, as I would many times yet to come, how many personalities did he have? I waited to see if he'd snap, but he didn't seem like he would.

"Knives. I know you think you did the right thing, that you think people are parasites, but those were the good ones. I just don't understand…" He was laughing at me. Knives was mocking me, laughing like I was an idiot. I punched him in the lip. Before I had time to think about it, I was pinned to the floor, and I realized how strong Knives really was. His face was parallel to mine, and his lip was beginning to drip a bit of blood onto my mouth.

"Maybe they weren't so good, ya know?" The words came out a hiss, Knives' breathing rapid, his heart pounding, and my own blood deafening in my ears. I'd known he was crazy, but I was afraid. I'd never thought be might hurt me, and I understood that he wasn't really himself, that there was no Knives' just some maniac in his body.

"I'm sorry, brother I love you, I didn't want to make you mad…"

"I love you too Vash. I love you." He kissed me. At first I was upset by the blood, I didn't want to taste it, but then, I broke: if this was what Knives gave in his love, wasn't it only right that I return it? I kissed him back, closed mouthed, like Rem had taught us as children, a chaste show of affection. I was… stunned by how he was touching me now, and kissing me, and kissing me.

"What are you doing? Knives, what are you doing?"

"I love you Vash. Please, can I love you?"

"I love you too…" His hands were tugging at my waistline, pulling on my pants. His fingers were warm, and when he touched me, I became instantly rigid. I felt flushed, I felt so rushed, and I liked it. "Knives…"

"I love you Vashu, I won't hurt you…" He spoke to me between kisses, suckling-needy kisses, across my chest, across my throat, and on my face. He sat back a second to look at me, both his hands on my groin. I was stunned, but I had absolutely no basis of comparison, and it felt good. After a moment, Knives moved lower, he grinned at me, almost playfully, and I was afraid again for a second, but then he'd taken my dick in his mouth, and all I could think of was how great it really was. So this was love.

I was enthralled, and consumed by feelings I'd never had before. I had no way to comprehend what was happening, and I didn't even try. After awhile (an amazing while) my brother was kissing my face again. "Let me do that to you. That was wonderful…"

"No, I have something else I want you to do, okay?" His eyes were pleading, and I couldn't comprehend the emotion behind the cold steel.

"I love you Knives."

"I know. You're going to show me though, okay? This is special Vash, this isn't just something silly, this means that I'm the most important person to you, and that you're the most important person to me, okay?" I nodded.

Knives gave me a weak smile, and spat into his hand. He quickly lubricated me, and positioned himself above me. He had me hold myself, and lowered onto me. It was incredibly tight, I lost all conscious thought for a second, then I took my hand away. Knives smiled at me, and pushed himself further down. I pulled my head up, to look and see whatever I could, and I decided to massage his cock like he'd done mine. Knives ended up helping me do that too though, and with me touching him, I immediately lost it. All said, I probably fucked my brother for two minutes or so, until I blew my first load into him, and lay back in spasms. He masturbated, sitting astride me like that for a few minutes longer, and as I watched, he cupped his hand and caught most of his semen. What landed on my belly, I ran my finger over, and tasted.

We lay there holding each other all night, and once he was asleep, I was left with my own thoughts. If that was love, why did I feel so numb? So empty? And if that had been something so special, why had I done it with him? I could barely take being around him. I wanted to cry, but I didn't want to wake him up. I didn't want to see him, or ever do that again. It had been hard enough trying to tell myself to leave before I had done that with him, and I was so confused I didn't think there was any way I could leave him now. He would die. It would kill him. I couldn't let myself be the cause of my brothers' death, so I stayed, and pretended to love him, and quickly enough, learned to love his special attention.
