A/N: So! I thought it'd be a hilarious fanfic idea where Tamsin is turned into a guy and has to cope with becoming a guy suddenly. One-shot for now. Valkubus. Rated T.

Just a heads up, I wasn't sure how to deal with the whole "he vs. she" pronoun thing considering Tamsin would still be a woman in her mind, but a guy on the outside. As a result, I decided to have everyone refer to her as "he" when in dialogue, but in the narrative bits, she'll be referred to as "she." And if there will be any naughty bits in the future, I'm not sure how saying "her [insert any word for male bits]" would roll over. Thoughts? If I don't like the way it sounds, then it'll probably be just silly Rated T fun.

If you wanna know what a boy Tamsin looks like in my head just imagine someone kinda like the younger version of Alex Pettyfer when he had that tousled blonde hair and toned body. :p

Sudden Change

When Bo awoke in the day, she snuggled into Tamsin's warmth, breathing in the valkyrie's familiar scent. With her eyes still closed, she placed small kisses on her neck, trailing her hand down from Tamsin's neck to her breast where she was met with— Flatness? I know Tamsin's breasts aren't the largest but.. they're soft and there's definitely substance to them.. As Bo thought, she moved her hands upwards, past Tamsin's neck and to her cheek where she found stubble. At this, Bo's eyes shot open, and she jumped out of bed and away from whoever the hell was in her bed.

Tamsin, who was pretending to be asleep just so she could enjoy Bo's ministrations, opened her eyes grumpily, upset that Bo didn't continue what she started. When she looked at Bo, she could see raw horror in her eyes.

"Bo, what's—" Tamsin started, but stopped when she heard the bass to her voice. What the fuck?

"Who the hell are you, and what have you done with Tamsin?" Bo demanded in an angry voice, reaching for her dagger.

Ignoring the deepness of her voice, Tamsin focused on calming her girlfriend down. "Bo, please, it's me. I'm Tamsin. I swear to you."

"Bullshit! Last I checked, my girlfriend was— OH I DUNNO— a freaking girl!"

What? Tamsin thought in disbelief, glancing down at her body. Holy. Shit. Where she thought she'd see the same breasts she's seen for lifetimes, she found nothing but pectoral muscles that lead to defined abs and a happy trail beneath her belly button.

"Holy fuckballs, Bo."

"Okay, quit saying my name like you know me!" Bo shouted, waving her dagger menacingly close.

"Please, Bo, trust me. I'm Tamsin, and you are the beautiful succubus with whom I have bonded and entrusted my heart. We've been living together in this shit house of a place you've called home since you came to this town for 6 months now. I gave you that ring on your left hand on our bonding day. If you still don't believe me, just look in my eyes, please," Tamsin begged.

Bo breathed heavily, finding her resolve melting away. She sat down on the bed, clutching her dagger tightly. "Okay.. but no funny business. No touching. Nothing."

Tamsin nodded eagerly as Bo got closer.

The brunette took a deep breath, closing her eyes while doing so. When she opened her eyes, vibrant, wild green eyes stared back at her, and she knew right then that she was wrong in threatening the blonde.

"Tamsin.." Bo whispered, wrapping her arms around the blonde and pulling her close. In return, Tamsin slid her arms around her, hugging her tightly. Bo pulled back, staring at her intently before speaking.

"What the hell happened?"

"Your guess is as good as mine, succubus."

Bo toyed with Tamsin's hair, shocked at how messy and tousled it was and how it still felt exactly like the blonde's hair from before. She leaned in, smelling it.

".. Bo, are you sniffing me?" came a deep rumble.

Bo jumped, shocked now by how deep and smooth Tamsin's voice was. "Jesus, Tamsin, the voice change is really tripping me up. And yes, I was sniffing you. You still smell the same."

"You're weird," Tamsin spoke quietly, smiling.

"Oh, I'm weird? Did I magically turn into a dude overnight?"

"Point taken."

The succubus stopped talking for a moment, taking time to let her eyes wander over the new and foreign body that her girlfriend now inhabited. Her eyes trailed over broad muscled shoulders which lead to strong biceps, and she stared at the Adam's apple that was now present. Going lower, she witnessed Tamsin's flatter and more muscular chest and when she glanced lower, she stopped briefly.

"Tamsin, why do you have a boner?" Bo asked, staring at the tented part of the sheets.

"Wha—?" Tamsin let out, confusion spread across her features. She was too caught up in the way Bo's eyes were staring at her body, soaking in the new details. Finally, she glanced down, staring at the betrayal of her new body. "Oh. Oh."

"You still haven't answered my question," reminded Bo, her eyes glued to the lower half of Tamsin.

"Well.. usually, when we fight and make up, we have angry make-up sex and.. we just fought.. and you're naked.." Tamsin trailed off, vaguely embarrassed.

"I see," Bo observed before lowering her voice and reaching her hand out. "Can I see it?.."

"Bo, whether I'm a woman or a man, all of me is yours," Tamsin replied softly in the brunette's ear.

The succubus reached out hesitantly, drawing closer when—

"Bo-Bo! Tam-Tam! Get the hell up! It's 2 p.m., and I'm lonely," came a familiar voice. Just after the sentence was finished, Kenzi barged into the room and stopped in her tracks at the sight before her. Bo quickly covered herself up with the sheets.

"Kenzi!"

"What the fae is this?! Bo! Didn't you pledge your hoohoo to the blondie? And here you are cheating on her with some mighty fine man."

"I can totally explain!"

"Explain that you're a horrible cheater, and Tamsin doesn't deserve this? Explain the mystery man in your bed? Explain the fact that he looks like a Norse god? Explain—"

"This IS Tamsin," Bo interrupted.

Kenzi stopped her tirade, staring in disbelief at the man in her best friend's bed.

"Hey, meat bag," Tamsin finally spoke, a smirk on her face.

"DUDE, you're a dude!"

"Good observation skills. I'm not sure why you aren't a detective by now," Tamsin rolled her eyes.

"I demand an explanation!" Kenzi stomped her foot definitively. "This kinda friendship has rules, y'know."

"Well," Tamsin began, pecking Bo on the cheek before she stood up. "I've gotta pee."

Bo and Kenzi watched as Tamsin grabbed a pillow, covering her crotch and heading out the room towards the bathroom.

"Tamsin makes one good-looking man, Bo. My body is confused."

"My mind is confused.. My body, however, definitely wants all of that new Tamsin body."

"AND she.. he.. he's got a donk. Wait, do we call Tammy a 'he' or a 'she'?"

"We can totally ask whenever Tamsin's back."

::::

Meanwhile, Tamsin stood in the bathroom, stark naked. She stared into the mirror, gazing at the manly features that now made up her face. Her old features could be found in this new face, but now they had a manly edge. In addition to all of that, she now had facial hair. Tamsin reached up, rubbing her palm against the pinpricks of hair. Afterwards, she got distracted by how much larger and thicker her fingers were. This is too fucking weird.

She raised her arms up next, staring at how the muscles beneath the skin moved. She flexed her arms, watching the muscles bulge. She followed the happy trail she now sported which lead to the one thing which obviously indicated she was now physically a man. In food terms, where she had a muffin, she now had a sausage. An impressive one, I might add. Tamsin nodded thoughtfully, staring down at it.

But, it doesn't look like it's going down anytime soon.. and I need to figure out how to pee with this thing. Tamsin tapped it with her hand, watching as it moved from side to side before resuming its original position. She poked it with her finger now, oddly fascinated by it. If I did this with any of the guys I've been with, they would have definitely marked me as crazy. She pulled out of her trance, focusing on the task at hand. Peeing.

The valkyrie walked to the toilet, staring down at it. She tried several stances, attempting to aim in the toilet without making a fool of herself or making a mess. After several failed attempts, she sighed, using the pillow to cover herself up and go back to the bedroom.

"Bo, throw me my phone."

"Why?" came a confused reply.

"Just— just do it, please."

"Okay.." Bo consented, suspicious. She tossed her the phone, going back to explaining to Kenzi the events that unfolded when they woke up.

Tamsin walked away again, hanging her head in shame once she got to the bathroom. She pulled up the internet app on her phone and went to Google's search engine. Her fingers were different, but they still were nimble and precise. The blonde began tapping the screen, entering her question. How.. do.. you.. pee.. when.. you... have... a boner?

She tapped enter on the search and waited as several responses came up. She read them, half-horrified and half-amazed at the different ways men have managed to urinate while maintaining an erection. She read one response in particular about a man who claimed his method worked 100%, but it was difficult.

dude its totally possible to pee with a stiffy! ive done it like 1000 times lol and my method works every time man. you just have to plant your feet on the wall above the toilet and your hands on the ground like youre abot to do a handstand. make sure u position your stiffy right so it points at the toilet

Tamsin furrowed her eyebrows, staring at the comment. I can totally do that, she decided. She put down the phone, stretching her arms and legs. Wait.. who in their right mind stretches before peeing? What is wrong with me? Did becoming a guy make me an idiot? Tamsin shook her head and got into position. She noted where her pointy friend was before doing her business. She let out a content sigh as she did it, relief flooding her system. Afterwards, she wiggled her hips a bit, shaking off excess.

When she was finally done, she threw her arms in the air and yelled victoriously.

"YES!"

::::

As Bo and Kenzi finished their discussion, they heard Tamsin's manly roar from the bedroom. They looked towards the bathroom before looking at each other.

Kenzi spoke first. "Dude, I don't even wanna know."

Before they knew it, Tamsin came bounding into the room, a towel wrapped dangerously low around her hips.

Kenzi stared helplessly at Tamsin's new physique, almost drooling at the sight of the V formed at the blonde's hips. Without even realizing it, Kenzi spoke in a flirty voice.

"What's got you so excited, Mister Hunk O' Burnin' Love?"

Bo didn't miss a beat as she smacked her best friend's arm. "HEY, that is my girl— boyfriend you're ogling!"

The human snapped out of her reverie. "Oh, right! What pronouns do you want us to use for you, blondie?"

Tamsin paused, thinking about it. "Well, it would probably be easier to just use dude pronouns until we figure this whole thing out."

"Would ya look at that, Bo-Bo.. Who knew you'd get a 2-in-1 deal with Tam-Tam here? Aren't you glad you play for both teams?" Kenzi nudged her friend.

Bo simply sighed, covering her eyes with her hand in an attempt to deal with the whole situation.

"Oh, and why were you hollerin' like that, boy? Confused the hell out of me and Bo here."

Tamsin grinned a boy-ish smile, "I peed."

"Well.. I guess we've all got different definitions of success," Kenzi said, her eyebrows knitting together in confusion.

A/N #2: Bada bing, bada boom. Should I continue, or nah? My feelings won't be hurt if you all say no, haha.
