Hi, Taka here with another one-shot. This time is kinda strange. Let's take a look...

Excalibur x Valkyr

Excalibur was on Earth, Rescuing a Tenno from the Grineer. It was supposed to be an easy stealth mission, In and out before they even noticed. But as soon as he went in the structure, in front of him was three Grineer Lancers. Two of them shot at him while the third went to sound the alarm. When he took care of them, the alarm sounded. He sighed before taking out his Aklex Prime and ran towards the objective.

Every now and then, when he killed a few Grineers, he would feel someone staring at him. He would turn around, find no one there and then a shadow would move pass his vision. He shrugged it as a animal and continued onward, not knowing that someone is indeed following him. Halfway through, He saw a bunch of dead grineer, majority of them having claw marks and some of them without limbs.

He remembered hearing rumors about a warframe that has claws like cats and going around killing grineers but he didn't believe it. It was nothing more than a myth because said warframe was supposedly a corpus experiment. What type of experiment he did not know but not willing to find out.

He came across the holding chamber and there were three wardens. He killed them quickly as not to alert the rest and went to unlock each door until he found the Tenno. He nodded at him and he extracted him before preparing to run. Before he started running, he saw a codex beside the holding area. He went to collect it and ran towards where his ship was waiting.

Unknown to Excalibur however, a warframe was following him closely. When he reached the ship and went up the ramp, the unknown frame dashed into the ship as well. When the ramp closed and the ship flew into space, he sighed and went to his arsenal and kept his weapons before going to the navigation system and setting a course to the dojo. "Operator, glad you are back uninjured." The ship cephalon, Siris, said.

"Well glad to be back. My neck is sore. set a course to the dojo, i'm taking a break." Excalibur said before sitting down and taking out the codex he got from the grineer base. "Erm... Operator? Who is that guest you brought into the ship?" Siris questioned. He was confused by what he meant before turning around and getting a shock.

There behind him was a warframe sitting like a cat, red color painted her armor and blue energy outline. He blinked twice and confirmed that he wasn't dreaming, staring at him was the myth. She tilted her head at him before moving or in the case, crawling closer to him. The movement broke him out of him state making him shake his head and asked the first thing that came to his mind.

"Can you understand me?" She did not move for a few seconds before nodding. Excalibur sighed in relieve that she could understand him and went to the in-built kitchen he installed after one year since he rarely return to the dojo or any of the relay. He took a container of biscuits and went back to the navigation room where Valkyr was no where to be found.

When he looked around, something landed on his back, making him bend forward due to the force. He then heard mewing sound coming from his back. Turning his head, he saw her staring at the container in his hand. He opened it, took a biscuit out and held it to her. She sniffed it a few times before biting it and munching slowly.

She then mew softly as if asking for more so he went to sit down, Valkyr still on his back and pour a few biscuit on the cap of the container, giving her easy access. She leapt from his back to the floor and begin eating. He then took out the codex and begin reading it.

Valkyr, Cat-like Warframe:

She is an experiment from the corpus. It is said that they tried to tinker with her powers but failed, making her act like a cat. During the confusion, she escaped from their clutches and disappeared. She could understand human speech but it is unknown whether she could speak or not.

He then looked at her and wondered. 'Experiment? How did they even find her...' He then continued reading.

She has quick reflexes, highly agile and is very strong. Her claws are made of energy and could tear metal apart. She could take down a heavy grineer squad in seconds. She is considered dangerous and must be shot on sight.

When he read finished, he turn to the side to see her curled up sleeping, the cap now empty. He smiled at how cute she looks before taking the cap and keeping the container. He then went to his foundry to upgrade and tinker with his weapons.

When she opened her eyes, she did not see the warframe anywhere. She then uncurled herself and went defensive, thinking something bad has happened to him. When she heard him mumble, she relaxed and moved to the foundry where she saw him tinkering with his pistols. She crawled over, not making a sound before leaping onto his back.

"Oopffff!" He exclaimed when there was a force applied to his back suddenly. He then turn around to see her smiling at him before smiling back and went back to reassemble his pistols. She crawled into his lap and sat there, surprising him for a moment. She then looked at the gun before starting to assemble the parts to its correct place.

He watched in awe as she put each part into the correct place and a few minutes went by before she was done, the weapon looking as if it wasn't even taken apart in the first place. She held it out to him as he inspected it, nodding at it. He then smiled at her. "Nicely done, perfect assemble. You are talented." She then smiled and mew at him before curling up on his lap.

He smiled at the sight and went to pet her. With each pet, she leaned closer to the hand and mewed. He then stopped when he heard the transmission ping. 'Another mission... ahh well the break will have to wait.' He thought as Valkyr looked at him in confusion. He smiled at her before carrying her, standing up and proceeded to the navigation systems.

She then uncurled herself and jumped to the chair, perching herself while he went to the comms. 'An extermination quest on the corpus... Ah well I could always use the credit.' He hit the accept button before Siris said. "Updating coordinates." He sighed as Valkyr crawled to him, worry showing on her face. He then chuckled.

"It's nothing. Just an extermination mission on the corpus." He then beckon her to come closer which in his surprise, she did. She leaped onto his lap and looked at his. He smiled before laying downon the floor, Valkyr curling on his chest. He put a hand over her as he went to rest. "Siris, wake me up when we are there." He heard an understood from the ship before falling asleep.

Unknown to him, Valkyr was having a nightmare. She was bounded to a table as the corpus science wrote notes down. He then picked a scalpel and cut into her stomach, making her scream in pain. He then begin writing more notes down before removing the scalpel and started cutting her, the voices of her scream could be heard in the base.

Excalibur awoke to someone shaking and shivering. He looked up and saw Valkyr sobbing. Shock was an understatement as he quickly sat up and shook her. "Hey! Hey wake up!" She then started screaming as she sat upright, claws appearing and striking out by reflex, catching him in the chest. He yelped in pain and surprised before she leapt back eyes wide and panting hard.

She then looked around and her eyes fell upon him, three claw marks on his chest. She then looked her hands before going wide eyes, realising what has happened. They did not move for a minute before he could hear her sob and she took off into the foundry. He was stunned by her behaviour before standing up and going after her.

After a few minutes of searching, he found her curled up and hiding in the corner of the cargo bay where all his resources are kept. As he approached, she curled up even more as if she is afraid of something. She mewed softly as Excalibur went closer. He kneeled down and pet her before trying to make her uncurl. When she finally did, he sat down and stayed close.

"Did you have a nightmare about the experiments?" He asked. He got his answer when she started crying again. He turned and hugged her, making her hug back, sobbing. "Don't worry, you are safe with me..." He pet her until she fell asleep in his arms. "Siris. Do me a favour and find out which corpus base she was experimented on and do it in 20 seconds."

Siris instantly went to search as when he was serious, things is about to go to hell.

"I have found the location. It is the same place as the mission you just accepted."

As Siria said this, He nodded. 'Small Galaxy it seems.' He then carried her and moved to the foundry to his makeshift bed that he made incase he needed to sleep. He placed her on the bed and tucked her in.

"Siris, how much longer to our destination?" He heard a faint twenty minutes before he went to his arsenal and took out his Paris prime, Aklex Prime and his Dragon Nikana. He tested the sword a few times before he nodded and went to the ramp where it opened. "I'll be back in ten." He then jumped.

When he landed, he drew his bow and sniped a few corpus. When he saw a scientist, he stealth up to him and grabbed him, placing his pistol to the scientist head. "Tell me where the Warframe Valkyr was experimented on and I will let you live." He said the location immediatwly and he pulled the trigger. He hated scientists.

He then proceeded to the location, killing every corpus that is in his path. After he reached the lab and entered, he saw a sole scientist writing something down. When he looked up, he freezed. "Are you the one who experimented on Valkyr?" He nodded his head in fear as Excalibur was cobered in blood.

He then walked to him before giving his a punch to his mask and throwing him onto the floor. He then mounted his and punched his mask repeatedly until it broke. He then drew his Dragon Nikana and pointed to his stomach. "I'm going to let you feel what you do to her..." He then pierced the scientist stomach, making him scream.

He then moved his sword slowly to the right and then left, cutting his intestine and leaving him there to die. He looked around the lab trying to find any reports on her when he came across a codex that says 'Escaped' as the title. When he opened it, he saw Valkyr. With each picture he came across, His eyes darkens.

Half of the pictures contains her being cut open while the other half was her being bound and naked while other corpus units were watching, some even had their dicks out. He was about to burn the folder when he came across a picture that surprised him. She was smiling, playing with the kubrows that the corpus captured. He kept that photo and burned the rest.

As he begin to walk out, his eyes full of anger and darkness, he heard someone say. "Release me, and I shall help you out"

He sighed and replied to the voice in his head. " I told you i'm not going to use your power, Prime." Prime chuckled and said. "Don't you want to get revenge on those who hurt her, those who see her as a plaything?"

Excalibur sighed. "Fine but this is the last time." He then walked to the door where he knew corpus units was waiting for him. "Of course Master, I would only live in your head to serve you..." He let Prime take over his body. What was once Excalibur is now Excalibur Prime. "It's showtime..." He said darkly as he walked out the door. "Don't forget, destory everything." Excalibur said.

"With pleasure." At this, he ran through the door, catching the corpus units off guard and charged his energy up. With each kills he gotten, he charge faster. When he was charged. He went to the center of the building. "Time to disappear..." Prime said as he released all of his energy, decimating the whole building and the corpus with it. The sphere just stopping before the ship.

Prime then returned the body to Excalibur. "That was fun... Can't wait for next time." Excalibur chuckled at this and replied. "You sure did a good job. Maybe next time." Prime only laughed as he fades away, leaving Excalibur alone in a now cleared of buildings field. He then proceeded to the ship as Siris greeted him.

"You are back Operator. In exactly nine minutes and forty-five seconds." Excalibur chuckled and said. "Close enough. Now set a course to the dojo." He heard a roger before he went to see how Valkyr is doing. When he reached, she was still sleeping so he sat on the bed, petting her head. "No one is going to hurt you again..."

He must have been a bit rough because Valkyr opened her eyes. She looked at him before mewing. He chuckled and took the photo out, showing it to her. She went wide eyes and she snatched it out of him hands, tears threatening to drop. "I destroyed everything. The buildings, Labs, everything. I would never let anyone hurt you again. Not while I still live..."

She looked at him and her tears begin to fall. As she sobbed, Excalibur brought her to a hug. She returned it, pressing her face to his neck. When he moved back, Valkyr took the chance to move forward and kissed him. He was shocked for a moment before relaxing into the kiss. Valkyr then broke it before pushing him onto the bed and straddled him. She then moved down to kiss him again while removing his armor.

He realised what she was doing and broke it. "Are you sure?" He got his answer when she removed his armor and hers. When he saw her body was filled with scars, he traced each one of them, making her mew in content. He took the chance to flip them over, him being on mewed in surprised as he positioned himself. "You sure about this?" She nodded before mewing once again.

He then penetrated her slowly, her mews of pleasue slowly rises in volume. He stopped when he felt a barrier. 'Hers is still intact?' He thought before looking at her. She nodded and pulled him down to hug him, bracing herself. He then pierced it in one thrust making Valkyr yelp. She then bite down on his neck, making him wince.

After a while, She released her mouth from his neck and nodded, telling him to move. He complied and start moving. Each slow thrust drew out long mews of pleasure from her. He then picks up pace as he felt that she was prepared enough. Her small mews turns into full moans. When he thrusted into a certain spot however, She shierked and Excalibur felt her walls clamped down on him.

He moved, hitting that spot over and over again, making her writhe and squirm, screaming in pleasure. When he felt the pressure built up, he picked up the pace. "I'm about to cum..." Valkyr only respond was her moving her hips to meet his thrust. Not before long, He grunted and came into her, painting her walls white with his seeds, her walls clenching on him, milking him.

He panted as he came down from his high. He tried to pull out when Valkyr used her legs to wrap around him, keeping them connected. She mewed and turned, him being on the bottom and her being on top. She then starts to move up and down slowly, simulating his already sensitive dick, making him moan. She took it as a sign to move faster.

Whenever she when down, he went up to meet her, each meet making her moan and pant. Excalibur then grab her hips and begin pounding into her, grunting. Not long after, they both came together. Valkyr laid on his chest, tired and Excalibur wrap a hand over her and turned, placing her on the bed and beside him.

She snuggled into his chest as he reached down to bite on her neck making her moan and doing just like what she has done, marking each other. "Mine." He said to her before she giggled and cuddled with her Knight. Before said knight fell asleep, He heard a very soft, silky smooth voice, say "I love you..." He smiled and replied. "I love you too... My kitten..."

So Another Pairing have been done... I really feel sinful... Ah well. I don't care.

See you guys next chapter!
