Kara walked through the suburbs of National City that Christmas Eve. She had had a fairly busy day as Supergirl with multiple robberies. It always baffled her to see the number of people who decided to commit crimes on Christmas fall days. It seemed like her day wasn't over yet, too.

She passed by a tall blue and white neo-Victorian house that was decorated with colourful lights and a few blow-up decorations. Someone was skulking around on the peak of the roof towards the chimney. The last thing she wanted was some scumbag ruining kids' belief and trust in Santa Claus.

"Hey, come on, get off of that roof, sir!" she called to him. The man looked around, startled by Kara's loud voice and tripped off of the panels. He slipped off of the roof with a loud skidding sound and the impact against the ground.

Kara quickly flew around the corner of the house to where he must have fallen, but all that was left was his suit. It was honest to god Santa suit but he just vanished. His body had disappeared with no footsteps or clues to where he went. At first, Kara looked around her, hoping that she was just high and that this wasn't really real life, but from what she knew, this was actually happening.

She grabbed the perpetrators clothes which included a large thick currant red jumpsuit, coal black boots, a black belt with a gold buckle and a matching hat with a fuzzy white trim. Kara pulled out her phone and took a quick picture of the suit to show Alex, but decided against it and put it on. It would be hilarious to see her sister's face, she thought. She pulled on the clothes which at first glance looked far too big but seemed to actually fit her perfectly.

A large chunk of snow fell on her head. She looked up at the roof to see why and noticed the tapping and clicking of feet on the roof. Kara flew up to find the source of the sound and found eight large deer on the roof strapped to a sleigh. She felt like a little kid back at an old Christmastown as she gazed at these glorious animals in front of her as they snorted and huffed in the frozen air. She looked around in the now snowy neighbourhood as she neared the beautiful beasts.

Connected to the sleigh was a long ladder with a golden plate that read, "The Rose Suchak Ladder Company". It must have been a dream or a cruel joke by DEO with some aliens or something. She walked back to the reindeer, looking at their golden plated harnesses. Kara pulled the tag a bit closer, "Comet", it read. She rolled her eyes and looked at a few others, "Donner", "Blitzen", and "Vixen". "Well, hey guys," she sighed, reaching out a hand to pet Donner on the snout. It let out a small sound and shook its head. "Oh... um... I don't know what to do."

Kara meandered to the sleigh and sat down in it. The seat was extremely comfortable and sank down for her. She shifted a bit and let out a calm sigh before grabbing the reins. "Go!" she commanded, getting pushed back into the back of her seat as the animals burst off of the roof in a second, almost as fast as Kara herself.

They finally landed after a minute and waited for her to finish her job. "Oh my god," she realised, "I just killed Santa Claus!" It took a moment for her to realise what had happened, but once she did, her body automatically pushed her to grab the sack of toys and pull out the correct presents.

She stood up and walked to the chimney. "I literally don't know what I'm doing," she panicked as her body began to slide down the pipe and into the home. She looked around the messy living-room as she was again pushed to the Christmas tree to place the presents. Kara was almost determined to not move for the rest of the night until this debacle was over and she could take off the suit. She was once again pulled up the chimney and to the sleigh.

She continued to the other houses for the rest of the night, flew through the air and giving out presents from the sack. It was fun to give gifts to children all over the world. She even got to go to Hawaii before the Reindeer flew north back home. The sun began to rise as they travelled to what must have been their home. It must have been the North Pole as they flew through dense snow. They finally slowed down until Kara was finally in a stable.

Small humans began running into the stable, unhooking the animals and bringing them into their respective stalls and wiping down the red sleigh. One of them walked over to her and took her by the hand, leading her out of the vehicle and through the stable. "Hello Santa," he began, not looking up at her, "I am Bernard, your advisor. If you could please follow me so I could explain some things." Kara nodded continued to follow Bernard.

"I'm in the North Pole, aren't I?"

"Yes, Ms. Kara Zor-El. In fact, you're now the owner of the North Pole."

"I am, how?" Kara asked as they entered a large house. "Well, since you put on that suit, you became the new Santa. Sit down," he commanded her as he held open the door. "So, within twenty-four hours, you will be transformed into a Santa which will make you look like a male human, but you must find a new Mrs. Claus to take over the last position. I wish you the best of luck. If you have any more questions, Judy will be in shortly," he finished in almost one breath before ushering himself out of the office. Kara glance around the warm room that was now hers.

"I can't believe I have to transform into a... ugh. Shit, why'd I have to walk home?"

"It's just a clause, no worries Kara, or would you like a more masculine name now?" a voice responded. A young woman stood in the doorway, her arms by her side. "Don't be startled, I'm here to help you. So," She smiled conjuring a cup of cocoa from thin air, "drink this."

Kara smiled and thanked her before drinking a bit and looking right at Judy, "Oh my god! You know how to make hot cocoa."

"I've had a couple of thousand years to practice, but I'm here for the marriage part. Normally a Santa would already be married, but I'd suggest to you Lena Luthor," Kara spat out her hot cocoa and turned scarlet red. Judy just continued speaking, "She'd make your life better. Since you both don't need to live here full time she could still be the CEO of L-Corp and still take on the role of the new Mrs. Claus." She slowly nodded in response. Kara could ask Lena, she was always willing to do whatever it took to make her happy.

"Santa, for now, I'm going to be guiding you to your chambers. I suggest sleeping from your exhausting night." As if on queue Kara let out a yawn and followed her to a door in the office. There she was confronted by a large room filled with a big burgundy bed marked with gold and silver accents. There were folded PJ's on the edge. Judy left her so Kara could change out of her clothes and into the PJ's which had the El family crest on it. It was a nice and generous touch, but Kara just wanted to scream and panic; she couldn't think clearly anymore. Nothing made sense anymore, not even sleeping, but Kara closed her eyes and slowly drifted away.

She woke up the next morning with a strong headache and body pains as she had never had. Kara decided to blame it on her drowsiness and walked further again. She meandered to the sink whetted her face before grabbing a towel and drying off. When she looked up, Kara shrieked.

The first thing she noticed was the hair. Her fingers combed through the short hairs that mocked the same style of Winn and Mon-El. With a look of disbelief, she stared at herself in the mirror. "I guess it wasn't a dream," she muttered, her voice now lower than before. She brought another hand to her new face, glancing at the masculine features, realizing that she now looked even more like her dad but with a thin dark blonde stubble on her face.

"Carter? Kyle? Karam? Carl? Kyle" he decided. A sharp sensation tore through his body, making him double over in pain. He gripped onto the faux marble counter hard enough to feel it crumble under his hands. Kyle let out a moan, covering his mouth as he glanced at his reflection. He looked down at his crotch- the source of the pain- and covered it, feeling everything changing too quickly. He felt his once female genitalia grow and rest against the palm of his hand.

Kyle whipped his hand away and looked at his now flush face before finally composing himself. He stood up to his now even taller height and looked at himself in the now perfectly fitted pyjamas that brandished his family crest. Kyle could study at himself all day, he had to admit that he was a dashing young man. He walked back to his room from the bathroom and grabbed his phone. As he unlocked his phone, Kyle pulled up Alex's contact and texted her, untying his bottoms. "Can you get me some men's boxers?" he requested, pulling off his pants and underwear.

"Why"

"No questions, just get them," Kyle continued, pulling up his pants now that he had more room.

"See you in 15"

"Thx" he texted. Kyle shoved his phone in his pocket and flew out of the bedroom to his apartment in National City. The moment he touched down, there was a knock on the door. Without thinking, he opened it, smoothing out his hair. Alex held a bag of boxers and looked him up and down. "So you're the reason for the boxers, tell Kara these aren't free," she quickly explained, handing him the bag.

"Wait, Alex, wait. It-it's me... Kara. I'm serious," Kyle quickly added. "And I'm not crazy."

"Okay... I'm gonna leave." Kyle made the mistake of reaching out for her, instantly getting his arm pulled as she tried to break it. "What are you?"

"I'm Kara, Alex," he tried again, pulling out of her grasp. "I crashed here when I was thirteen after escaping from Krypton to take care of Kal-El. The Danvers raised us and trained me to control my powers. I saved you from a crashing plane making me the new Supergirl. You killed my aunt to save me and threatened to hurt Winn with just one finger. I know that you thought you were straight until you met Mags... I'm Kara," he almost cried.

"What happened?" Alex asked, reaching out and hugging him tightly.

"I... later," he rushed, grabbing the bag and going to his room. He undressed and pulled out a new pair of green boxers. Kyle had tried as long as he could to not look at what he was packing, even when taking off his original underwear, but couldn't help to see now. He wasn't too bad at all- at least when compared to the few he'd seen in his life- and in comparison, even when he was flaccid, it was still better than the others.

"What's going on?" Alex called from the other room. Kyle pulled on his clothes and joined her back outside. "What happened?"

"Would you believe me if I said I'm the new Santa Claus?"

"Um... I don't know, you're a dude now, so I guess so."

"I also need to get married in a day now. I was advised to marry Lena. How in the world am I going to do that when I am turning into a freaking guy! She's not going to believe me, Alex. She's going to think I'm just some random dude." Alex walked to Kyle's bed and mumbled

"I'm going to need whiskey," she huffed, going to the kitchen and pulling out the bottle she always stowed in the apartment. She took a long swig and set it down,

"Okay, so, start from the beginning, is this why you were MIA last night?" Kyle nodded, "and this is why you weren't at my apartment?" another nod "and now you have a dick?" Kyle scrunched his face but confirmed her question. Alex sighed again, "So, you're Santa Claus and you need to marry somebody within forty-eight hours? Do you know what will happen if you don't?"

"No, I was too tired yesterday. I didn't even freak out," Alex put her head in her hands and mumbled something incoherent.

"What?" She pointed to Kyle's body so he rushed to the bathroom and saw that he was even taller and broader than before. Kyle walked back, looking at the ground. He felt kinda bad that this was happening.

Alex suddenly stood up "Okay."

Kyle looked up with a crinkle in his eye, "Okay?"

"Okay, I believe you. It's strange that you're the new Santa Claus, but hey, I got to help my um... sibling out. Do you have a new name?"

"Kyle. I kinda like it," he nodded. Alex slowly nodded back before pulling him in for a hug.

She whispered in his ear, "Everything will be okay, we'll make sure that you get the girl and become the best Santa Claus ever." Kyle nodded with a chuckle against Alex' shoulder. Alex was right, all he needed to do was to be the best Santa Claus ever and he knew he could do that.

"When Lena comes by, can you stay with me to explain the whole... Santa thing?"

"Of course." Kyle nervously nodded and grabbed his belongings, looking around for anything at all that he could wear. Even Mon-El's clothes would do, but nothing, so he just settled with looking like a loon in his PJs. He took out his phone and rapidly typed on the keyboard without a second thought to bringing her by. Not two minutes passed when he got a reply of "be there in 5", a promise he knew she wouldn't keep because of her physical distance from his flat.

She actually seemed to arrive on time, though. There was a knock on the door and with that Kara stood up, she walked over and opened it. Lena stood in the doorway, a slight blush instantly appearing on her cheeks as she gazed up at Kyle. "Is this the emergency Kara told me about?" she jokingly asked.

"Yes," Kyle responded, moving out of the way. Lena nodded and joined Alex in the living room. The moment she sat down, Alex explained what had happened, noting that Kyle couldn't lie because of the detail only she and Kara would know. It took a few moments and a lot of coercing, but after Lena looked into Kyle eyes, she just knew.

"How did you get yourself into such a mess, sweetie?" she murmured.

"I just messed up."

"No, you just cared too much," Lena corrected.

Alex glanced between them and stood up, pulling out her phone, "So, I'm gonna go explain this to mom and Mags."

"Okay," Kyle nodded, as she escaped from the tension.

"Is there anything else you need to tell me?" Lena asked after Alex had gone. Kyle nodded in response and sat down on the coffee table across Lena. He hung his head before looking back up at his friend.

After a few moments of silence, he shrugged and said, "I'm Supergirl."

"Oh, I know that already," Lena nodded. "I mean, glasses only get you so far."

"True," he chuckled. "So, why are you a guy now?"

"Well, I learned a few things last night, for instance, Santa Claus is in fact real and... now I'm Santa Claus."

"What? Wait, what happened to the old one?"

"I don't want to talk about it, but I'm the new Santa Claus. As the new Santa, I need to marry someone within 24 hours and I was wondering if you could help me."

"Well," Lena began, leaning back against the sofa, "I've been waiting for this moment for a while, but I wasn't expecting it to be like this."

"Seriously?"

"Yeah," she nodded, "I'll help you. I have a few ground rules, though."

"Anything," he agreed as he leaned closer.

"First, you have to move into my penthouse."

"Okay."

"Second, I want us to have a real relationship, not just one for conveniences."

"Okay, what does that mean?" he asked, settling back on the table.

"Don't sleep with anyone other than me," she said. "It's just that simple."

"Oh, okay... I mean, I rarely ever thought about it, but we do get along very well," he pondered. "And if I'm being completely honest, those first months of interviews, I felt like I had butterflies in my stomach," Kyle continued.

"What about now?" Lena blushed, glancing at her feet.

"Now, I mean, I see you as my closest friend. My body's gotten a bit used to your presence, but I still want you," he nodded. "But thank you, Lena, it means a lot to me for you to always be there when I need you most."

"Can I ask you a personal question?"

"Sure."

"Nevermind," she whispered, a blush spreading across her cheeks while her ears turned red.

"What is it, Lena?"

Lena nervously covered her mouth and almost mumbled, "I... fuck... can I see what you've got... going on?"

"Oh, I mean, sure..." Kyle nodded, standing up and untying his pants. He hooked his thumbs under the waistband before sliding them down, revealing his boxers. Lena cocked her head to the side while he nervously began to pull down his boxers. She quickly reached out and grabbed the black band.

"Wait, I shouldn't be pressuring you, sweetie," she said.

"No, I haven't really... looked at it... or tested it out yet," Kyle awkwardly noted, pulling her hand away. He stepped out of his pants and knelt between Lena's legs. His heart began beating quickly as he looked up at her, unsure where to start. Kyle kissed the back of her hand and pulled himself up by her legs until he was up onto his knees, inches away from Lena's flush face.

He looked into her dilated green eyes, noting the way they seemed to explore his new features. Kyle- who was already pressed up against the couch- felt heat rush to his extremities and groin as he looked up at her. Lena leaned down and pulled him up for a kiss. She placed a hand on his scruffy face as she kissed him.

Her deft fingers moved from his stubble and down to Kyle's shirt, unbuttoning them to reveal the rest of his body. She opened her eyes, surprised at his slim not so muscular body. Unlike his bulky cousin, Kyle was still slight of a figure like Kara. Lena brushed her hand down his chest feeling where his chest hair would probably start to grow soon.

She leaned over into him, sliding off of the couch and into his lap. Lena let out a surprised yelp as she looked down at his erection. She glanced back up at him, noticing his embarrassing reaction to her. "Don't be ashamed," she whispered to him, nibbling on his earlobe.

"Oh-kay," he groaned. Lena reached down into his boxers, stroking his warm shaft with her thumb. A flood of pleasure struck her spine as she wrapped her hand around his hardening shaft. She pressed a few more kisses against his neck, tasting the thin sheen of sweat that began to peak through his skin.

Her thumb continued to gently brush against the head of his penis, enjoying the power she held over him as he quickly grabbed her shoulders. Kyle rested on his heels, leaning into Lena to kiss her again. He slipped his tongue into her mouth, sliding around her tongue as she continued to jerk him off.

Lena pulled away from their kiss and bent over to kiss his chest, kissing his nipple and placing soft kisses against his chest. Before finally wrapping her lips around his- "Wait," Kyle moaned, pulling her back up by her shoulders, "Wait."

"What, do you want to stop?" "No, I... I want to... I want to know what it feels like," he asked. "Oh, yeah," Lena nodded as she undressed. Kyle helped her with her blazer and pantsuit until she was in her bra and underwear. He pulled off her bra, sucking her breast into his mouth, leaving a small hickey on her breast before he picked her up, wrapping her legs around his waist and walked her to his bedroom.

Kyle rested her on his sheets, looking down at her beautiful body. The sight sent fresh blood through his core. He felt the throbbing sensation of pleasure through his body, making him want to tear off her clothes. Kyle slipped her underwear off and began to stroke himself. "Should I... like... rubber up?"

"No, you're good to go," she affirmed as she propped herself up on her elbows. Kyle nodded and slowly slid into Lena. He let out a low moan and began to pump his hips into her. He leaned down to kiss her, amazed by her warm wetness as she ground down against him.

Lena pulled him close and placed her hands against his hips, pulling him against her. She yelped again as Kyle licked his fingers and pressed them against her clit. Lena moaned against his lips, groaning at every movement from his hand and hips. She was surprised at how long he lasted before he finally came. Afterwards, she pulled him in the bed, joining him after a short break to sleep in his arms.
