OlderBrother!Vamp!Prussia x YoungerSister!Reader

    It started around the time of his second year of high school. An attack at a shady party in the woods left him like this. Gilbert only managed to get away, but changed his life completely. But hey, chicks dig Vampires, right?

    He craved blood, whether from the local blood drive, or maybe the living being once in awhile. But with you it was different. From the time you were little (h/c) toddler, Gilbert was always protective of you. He was constantly teased by his friends of his "overly fond" affections for his sister. His younger brother was always so grown-up, but he never noticed when Gilbert's brotherly affections turned sinister. Love turned to lust, and that was extremely dangerous for the one he lusted after

    Gilbert's blood thirsty habits where hidden quite deep, but only for you he would spill his secrete. 

    Only for you.

    You had always know that your brother had something hidden deep within himself, but you never bothered to ask. You were too busy with school, friends, and other things that held you attention. You were slow to pick up on things, so you didn't notice when Gilbert became more touchy with you. Stroking your arm, rubbing your back, and sneaking up on you from behind.

    He would almost always make the weird whining noises when a friend of yours, or his butted between you two. But a stiff smile would spread like butter across his face. His red eyes would do this odd twinkle, and the whine turned into a low growl. You then proceed to throw a concerned look over your brother, before focusing on the third person in your party.

    You would have never guessed that it was lust dancing in Gilbert's crimson eyes.

    "Hey Gilbert, I am hungry, you should buy me something." You tired eyes glanced over to Gilbert, his amused ones met yours.

    "Why should I do that (Name)?" He looked straight ahead, the rhythmic tap of feet echoing the shortcut alley you and Gilbert took everyday to and from school. The sun was setting to your backs, casting taller shadows than you were used too. Waiting on Ludwig had tried your patience after he said he would walk home alone later, and encouraged both of you to go home.

    "Cause, I asked Axel to give me something, but him being somewhat of a prick, he said to ask you." You trained you eyes forward, but casting then to your left to gauge your companions reaction.

    "I guess I could go for a bite." Gilbert laughed, as if he had an inside joke with himself.

    "Yeah, but only if your paying!" You joked back at him, giggling a bit and poking his side. Though, something about his demeanor changed, like a over-bearing aura flushed through Gilbert. You notice the tick in his neck, the clasping and unclasping of his hands. And then he licked his lips. For a second, you though you saw the gleam of sharp incisors.

    "Oh, I von't be the one paying..." His voice dropped several notes, and a low growl emitted from his throat.

    In a the span of a second, he was atop you, pinning you down to the brick wall with power you thought the teen could never bear.  His head resting near you shoulder, propped against the wall. You could feel his hot breath puff on your shoulder, as if he was fighting to control himself.

    "Ha ha, very funny Gilbert. Now get off me." You ordered with a shaky voice. Something deep and sinister awoke in the dear brother you loved.

    Something unnatural.

    "Why vouldn't I joke with my dear sister? It is too fun to tease you, (Name)." The hand propped against the wall, slid to your shoulder, and the to your waist. His grip tighten when he felt you shiver, and try to jolt away. His thumb stroked slow circles into you side, trying to calm the panic that fluttered in your abdomen. 

    "G-Gilbert! This isn't right! We are siblings!" Despite your refusal, your face still beamed red. You had never been caressed like this in your entire life. You saw his head lower, and could feel the growl on his lips. 

    "But zhat makes it more fun, (Name)." He breathed before setting kiss on your neck. His hand on his waist wandered lower, his fingers drummed a noiseless tune as he cupped you ass. A breathy gasp escaped you lips and you felt yourself redden even more.

    Gilbert took the chance to plant kisses up and down your neck, squeezing his hand that cupped you backside to feel you arch under his touch.

    Yes, this is what he craved for. You moaning and arching under his ministrations. This is what Gilbert craved for, this forbidden love.

    His lips found yours in a feverish haze, and he kissed you deeply, but was somewhat surprised when you returned the gesture. Letting your arms slide to his neck, wrapping them calmly around. 

    The low rumble of his appreciation shook you to your bones. This was so wrong, but yet felt right. His constant touches to your body left you breathless, a flush that only got deeper as he continued.

    Running out of air, you pulled back.  Though, Gilbert wasn't done. He snatched your bottom lip with his teeth, and sucked affectionately. You felt the bite of his teeth dig into you soft flesh, but it was a small pain so you dismissed it. It was only then that you noticed that the two of drifted closer by some gravitational pull, your hands scrunching up the black hoodie between his shoulder blades. Your pelvic regions grinding together fluidly.

    "Gilbert! We really shouldn't this! Its so wrong!" You choked out between breathy gasps. Gilbert only took your protests as a chance to kiss you again, and to let his hand wander towards your chest.

    "Mmm, but you like it. You vouldn't squeal if you didn't!" You gave him a questioning look before he tightly squeezed your right breast. A mixture of a moan and squeal escaped your lips, and Gilbert only smiled proudly.

    "See you can't deny ze awesome me!" He only leaned down and kissed your jawline and continued to squeeze. His left hand wandered to you thigh, where your school uniform skirt hiked up, almost exposing your panties. His fingers traced small circles, as you began to rub you legs together with a foreign feeling growing rapidly in your stomach

    The feeling to be touched.

    "Gilbert, we should stop... Someone might see us!" You gasped out, as the albino nipped and licked your sensitive spot. His hips grinding harder into yours, though you felt some sort of resistance forming in his jeans. His hands traveled up to the top of the crisp blue button down shirt, and popped the first one open with ease. His lips wandered down, almost reaching the valley of your breasts.

    "Gilbert!" With a great surge of strength, you pushed him off you. You set to work to fixing your skirt and shirt while ignoring the passion to be touched clawing at your stomach.
