Hello everyone! If you don't know already, this is the last chapter of this series! I am grateful for every single one of you who has come with me this far; it's been a ride! A whopping 12 chapters! This one is extra long since I didn't want to tease you, so I hope you enjoy this! Smut and blood play in this chapter! :]

Flying effortlessly, the pigeon soared high above ground, out of reach from everything around it. After an hour's travel in the bright blue skies, the bird swooped down, landing atop a windowsill. It walked around the wood before the glass window opened and a pale hand reached out, untying a clasp on its leg. Unraveling the curled piece of parchment, gray hues widened in surprised. The former corporal had been a bit skeptical of success, but the official document in front of his very own eyes proved otherwise.

"Eren…" The man walked over to the bed, crawling on next to his sleeping partner. Bright green eyes blinked sleepily, adhering to the surroundings. Rivaille showed the document to the vampire, and he too widened his eyes, a smile spreading across his face.

"This is good news!" He exclaimed, hopping up and hugging the shorter man, which only annoyed him. Rivaille pushed the boy off of him so he landed on his back on the bed.

"Get off…I will show this to your dad." He said calmly, getting up, throwing on a shirt, and stepping outside into bright daylight.

The former corporal blinked, the initial brightness stinging his eyes. But once he maneuvered through the various houses, he opened one, walking into a brightly lit room. No one was inside except for the doctor, who was having a mid-day nap in the far corner of the room. His footsteps were silent and the man wasn't aware of his presence until he spoke.

"Jaeger-sensei." The man opened his eyes slowly, taking a minute before responding.

"Ah, Rivaille. I trust you have good news?" The man nodded, stepping forward and showing him the piece of parchment which told of the good news. "'Based on numerous reports, one by Commander Irwin, another by Squad Leader Hanji Zoe, and a soldier named Mikasa Ackerman, the attempt to kill or capture Dr. Jaeger and various individuals, has failed due to the enormous and unparalleled strength of the vampire race. Half of the horses were demobilized and multiple soldiers reported back with damaged 3D gear. Therefore, with the large amount of evidence, further pursuit of these individuals is futile. In order to preserve soldiers and equipment, the warrant placed on these individuals is withheld until further notice.'" The man grinned wide. "This is good news indeed."

Rivaille nodded, a miniscule smile tugging at the corner of his lips. The older male noticed this, chuckling a bit in response. With the other man standing there, fidgeting a bit, he figured the shorter male had something on his mind.

"Is there something else you need?" Rivaille jumped a little, his eyes darted around the room in a slight panic.

"Um…Jaeger a-asked me to…ask you…if…you…had some…l-liquid…silver…" His face a bit pink, but Rivaille would never admit. It was embarrassing to ask the father of your future mate for something like this…it was almost like asking for his hand in marriage. When his answer was silence, he blushed a slightly darker shade of pink. "H-he said it's hard to…c-come by…" The doctor stared down the man in front him, watching his every move.

The doctor stood up, which made the younger male a bit worried. "Rivaille-san, do you love my son?" He flinched at the question. It took him a while to conjure up a response.

"Well, to be honest sir, I d-don't know what love is exactly. I didn't have p-parents or siblings, so I'm not well v-versed in the meaning of…l-love. But I do know this; Jae-…Eren saved my life. That speaks volumes to me…and I realized that I would definitely do the same for him." He took a deep breath, hoping he hadn't rambled too much. He always knew this talk would come. Hanji had practically told him about his future, and how he would find a nice (short) girl, marry her, bear her children, and live old together. Rivaille didn't think that could ever happen to him; he dedicated his life to being a soldier, fighting to save mankind. But now he was asking for a cup of fucking silver to mate with another man who wasn't really a man at all but the one creature he bound his life to killing, not to mention he himself was one of those creatures as well. It was a bit too weird a surreal for him. "I'm not sure if it's because of this new transformation, but I just can't keep myself away from him. Even now, as we're separated by a couple of feet, my chest aches."

It was the first thing he had admitted to another person his deep and personal thoughts. Then it suddenly felt like he was in a psychiatrist's office because he now found that in the event of him telling his emotions, he had lain down on his back on the nearest couch. He blinked, a bit confused as to how it all happened without him realizing it, but he made no attempt to move from his position.

"If that's what you call love, then maybe I do." He sat up, looking at the doctor with a serious look in his eyes. "That's why I want to…perform this ritual…" Rivaille took a deep breath. "I'm willing to put my life on the line for him, and he's willing to do the same for me. I think that says enough, right, Jaeger-sensei?"

It took a few moments before the doctor left the room for a few minutes, and came back with a goblet. It was fairly large and adorned with gold and silver. It was quite stunning, and the doctor held it between his hands carefully.

"You don't need to say anymore. I could sense your honesty from the second you walked in the door." The shorter male blinked, standing up as the doctor gave him the goblet. Rivaille looked inside and the smell burned his nose. "Don't inhale too much of it. There's not much in there, and Eren was right; it is quite hard to come by." The former corporal took the warning to heart, not liking the sensation the silver gave him. Then a weak hand was placed on his shoulder, and he blinked at the man in front of him.

"I trust you." Rivaille felt utterly relieved. "But you should go now. Night is almost upon us and tonight is the only full moon for another month. I suggest you don't want to wait that long, do you?" Rivaille shook his head and bowed out of respect to the older man.

"Thank you." He said before dashing out, heading to his (It was originally intended to be Eren's house along with his mate, so he figured the house was his now as well) home where a certain green-eyed boy was waiting.

"Mmmn…nng…" Muffled moans vibrated in their mouths, causing a bit of heightened pleasure for both of them. Hot tongues and slow-moving lips pushed against each other in a fiery fever, hands almost carelessly and lazily caressing pale skin. Their kiss was slow and gentle; they had all of the time in the world and had neither worries nor a reason to rush.

When they pulled their mouths apart, their foreheads stayed connected and they stared into each other's eyes. As the full moon shone through the cloud, both of them could feel the raw energy surging through their veins and they knew it was time.

Eren took the goblet first, letting Rivaille turn around and reveal the back of his neck to him. Slowly and carefully, his fangs lowered until the tips were coated in liquid silver. The pain ached in his teeth, and he hissed out. Hearing the sound of discomfort, he reached his hand back, finding the younger's hand, squeezing it gently. He didn't say anything, but the warm gesture spoke volumes in the place of words. Eren squeezed the hand back, leaning forward over the exposed flesh.

He sank his teeth and both of them hissed, half in pain and half in pleasure. Rivaille could feel exactly how deep the fangs were into his skin, and it was almost a cosmic moment that he couldn't describe. It was beyond the pleasure he'd felt in bed, but it was something that surpassed even pleasure itself. He could feel his soul…if he even had one…but something inside him stirred and melted with the young vampire behind him.

Rivaille's eyes were wide, unable to breath. Thankfully, oxygen wasn't key to staying alive, so not being able to inhale was not deadly. His grips on the other's hand tightened and he turned around, staring at a just as shocked Eren.

Again their lips crashed, mainly because they didn't have any words to say. There was still a bit of silver on the other's teeth, and the former corporal hissed as it burned his tongue. He pulled away, breath heavy. Eren then turned around, keeping his hand interlocked with the other. Rivaille then dipped his fangs in the liquid, breath hitching as the silver sent shivers down his spine. Then, he bit into the ample flesh before him, feeling the same sensation that Eren had felt only moments before.

The green-eyed teen cried out sharply, feeling their bodies almost melting into one. It was something beyond words as both of them had finally devoted themselves to each other, definitely feeling worlds different than before. It sent a pleasant buzz through their bones and their entire being. Eren turned around and they both clung together. Rivaille had never thought anything as incredible as this could happen in his meaningless life. He was a soldier, not a lover. But now, everything was…was…

There was not a word in his vocabulary that could sum up his feeling right now. It was foreign to him; he was not supposed to show emotion. He was a cold-blooded killer, ready to attack, kill, or eat anything that harmed his well-being. Rivaille never trusted anybody, let alone tie your life to someone else's. He felt his life changing completely, and it was for the better.

No more words were spoken that night. Not even their names were said aloud. Eren wasted no time in tackling the man to the bed, straddling him. He whimpered, almost as if his body was acting on his own. It was as of both of them were moving in unison, being able to feel each other's movements and feelings. Their lips crashed again, more fervently than before. Teeth clashed against each other clumsily, but they didn't care.

Since they had discarded their clothing long ago, everything happened quicker. They grinded their hips against each other, moaning and groaning as the pleasure was heightened tenfold. Under the full moon their sensations were higher, and it was beyond anything they had done before. Their hearts were racing, exactly in time with the other. Eren bit the other's neck, drawing a bit of blood as he continued down the other's torso. Rivaille grunted, hands tightening their hold on unblemished hips. Down his head went until they reached the leaking member belonging to the shorter male. For lack of patience and lube, Eren raked his sharp teeth against the flesh, causing Rivaille to cry out. Dark eyes looked up at his partner, silently telling him 'payback.' Rough hands moved from the hips to grabbing onto fistfuls of brown hair as blood seeped from his organ.

Using his mouth, Eren coated the other's length in blood, using it to ease the process along. Suddenly their notion of time was drastically changed. They were in a rush and the younger male whined and whimpered as he lifted his hips in the air, then carefully lowering himself on the bloody member.

Both of them moaned in ecstasy and they both felt their legs turn into jelly. It was as if their sensations were linked, because Rivaille could have sword he could feel everything Eren was at that moment. And as the young vampire rocked his hips, they couldn't form any more coherent thoughts. The heat of the moment took them in a tight grip, consuming them both in a flaming passion. The blood inside of their veins raced with anticipation.

"Nng…ah…nnn…mmmf…" Their moans were practically harmonized, playing a soft tune as their bodied moved sensually and quickly against each other. Not being able to breathe was an advantage for them, and they never slowed down. Air huffed out of their mouths, but fatigue never reached them. Rivaille met in time with the other's thrusting, slamming his hips up, the sound of skin slapping against skin filling the room.

Small tears pricked the corners of their eyes as the pleasure was soon becoming almost too unbearable. The symphony of moans reached an even higher pitch, both of their bodies moving erratically and helplessly against each other. They thrust and rocked continuously until their peak shot through their bodies.

Both of them came at the same time, white seed spilling as their climax rocked through them. Their breaths were heavy and limbs were weak. Eren collapsed against his lover, feeling like a mush of goo. Rivaille felt the same way as he couldn't even wrap his arms around the other male, silently staring at the ceiling. Then, as if on cue, the moon slipped behind the clouds and sank closer to the horizon with each passing second. The power that surged inside them earlier had faded to a dull sensation, but it was still there. It was the remnant of their commitment; their pact to dedicate their lives to one another until eternity, and even beyond that.

If they thought being a vampire in itself was strange, the feeling of their mating was way more strange, but a good strange. They both felt content, not needing to express their feelings verbally. They could almost read each other's minds. Dazzling smiled adorned their faces, along with light chuckles.

It was the first time that Rivaille truly smiled.

"Well, shit. Now I'm stuck with a shitty brat." Eren couldn't stop laughing, hitting the other's bare chest playfully.

"And I'm stuck with an emotionless dwarf." Rivaille blinked and remained silent and the young vampire honestly thought he had gone too far until the man laughed. It was also the first time he had a great and warm laugh. It was thrilling to him to be able to express their feelings to one another.

And he would be able to do so for as long as both of them lived. They were now linked in a way beyond comprehension; an impeccable and unbreakable bond.

"Shit…we're in deep aren't we?" Eren nodded, biting his lip to suppress a giggle. "And you know what?" The young vampire tilted his head. "I fucking like it." With bright smiles, they laid in each other's arms, exchanging sweet kisses and gentle bites of affection. As morning soon came, their bodies began to feel weaker. The energy that was spent in such a long and meaningful night needed to be replenished by a good day's of sleep and relaxation.

Slim fingers played with brown locks, and both of them were in a state of bliss.

"Ne, Rivaille…"

"Hm?"

"…Will they come after us again?" Rivaille tightened his hold on the other, kissing the top of his head, reassuring the young teen.

"Nah." The kiss and affection from the other made Eren feel at ease, as if a few little things actually calmed him down. It was amazing, how easy they were able to read each other and how much of an effect they could have on each other as well. "We're safe. They will leave us alone, and we can stick together until we grow old and die." Eren chuckled.

"But Rivai, we're immortal. We won't grow old or die." Rivaille blinked a little.

"Oh…right." After a few seconds of silence, they both chuckled gently, huddling even closer than before.

The sun barely peeked over the horizon, and their heads gently sunk into their cushions. A pillow cradled Rivaille's neck and his chest supported Eren. Their eyelids fell gently and their muscles relaxed.

"I love you, Rivai." Eren cooed, his voice gentle and soft. Rivaille smiled and whispered just as unconsciousness took over their senses.

"…I…love you too."

Well what a finale! It was great to draw both of their personalities out, especially Rivaille! It was entertaining for me and I hope it was for you! This is the last chapter of this series, but I hope you'll stick around to read my future works! RiRen seems like a very popular ship here compared to the other pairings I write, so look forward to that! Again you all have my thanks! Let's do it again sometime! :]
