What if/Genderflip: Macy, quiet Highschool Senior giving her first blowjob.

AN: As promised, first Sidestory!

You shouldn't need to read any of the Mason branch for this to make sense, but I might be too close to the tree to see the forest. Read until he leaves the party if you're unsure.

Enjoy!

Samuel Harwood was the hottest boy I'd seen in person.

He had that classic bad boy look with a heart of gold that made every girl want to either take care of him or get swept off her feet on an adventure. Wavy black hair he kept just long enough to always be windswept, framing sharp features and the bluest blue eyes that had ever blued.

It was honestly kinda crazy how many girls went crazy over the guy. He'd shown up to our tiny high school on the last semester of senior year. Rumors quickly started spreading like wildfire at how skilled he was in bed and how big his dick was. Half the class wanted to fuck him and it seemed the other half already had!

"Mnngrl?" I hummed questioningly around the dick in my mouth. My eyes locked on Sam's smirking face for his approval. Huh? You thought I'd be immune to his charms? What would make you think that?

"Just like that, keep swirling your tongue around the tip— hng!— Yes, you got it!" Long fingers tucked a loose lock of hair behind my ear and his thumb trailed along my jawline. "You're a natural cocksucker!"

I blushed heavily, somehow he'd made that sound like a heartfelt compliment. Though, that might just be me.

You see, I was what my friends Annie and Elizabeth called a wannabe slut. I was ready and willing to fuck pretty much any guy or girl who'd ask nicely. Only, I was too timid and plain to advertise that fact properly. My nineteenth birthday was two months away and Sam's dick was the first I'd seen outside of a hentai.

"I'm getting close, Macy! Where do you want me to finish?" Sam asked with a huff of exertion.

In answer, I shoved his dick further into my mouth, pleased all that practice with bananas and popsicles had paid off. Feeling his balls tighten up on my chin and his hands clench on the back of my head made me puff up in pride.

Yeah! That's right! I'm suckin' a dick like a pro on my first try!

What was I thinking earlier? Oh, right. I want to be one of those sluts who blows any guy who asked, but I'm too short and skinny for anyone to ask! I wasn't even cute and petite like Annie, who practically looked like a doll sometimes. All boney arms and stubby legs, that's Macy. My face was just...there in a way make-up couldn't fix without looking weird compared to the rest of me. Forget about clothing choices, nothing in my size exists in my price range!

So you can imagine how thrilling and validating it was when Sam didn't blow me off when Rachel dared me to blow him in this closet. Oh yeah, I never mentioned how any of this started! Okay, so. My friend Daniel has this basement where—

"I'm cumming!"

My train of thought was derailed by something much more important than backstory. The pillar of virility lodged in my esophagus pulsed as it shot its load down my throat. It was so warm! I pulled back to taste the last few drops and lick him clean.

Hmm, kinda salty with a bittersweet aftertaste. I swallowed with a shrug of my mental shoulders. Not bad, not great. Still super fun though!

My cheeks hollowed to suck the last little bit out. I grinned at Sam's crossed eyes and his wobbly knees. He looked drained of more than just his cum while I felt energized, heat spreading from deep in my belly.

"So, how'd I do?" I asked, twirling a lock of dark brown hair on my finger and playing with my sweatshirt hem. Wow! I thought I'd been horny before, that was nothing compared to now!

He huffed out a few ragged breaths, sweat dripping down his face. "Awesome, I've never had a girl do that before..." His voice faded into the background as the heat in my stomach flared into an inferno. Like Sam's cum was gasoline on a bed of embers.

Flames burned away everything that made me me until I was left with nothing but the core of who I was. Doubts and insecurities, hopes and vague ambitions, even connections to my friends and family evaporated. All that remained was one central tenet.

What would I want to be to best serve Sam?

An answer appeared in my mind without any conscious thought and the flames went to work making that image a reality.

My entire body was engulfed in scarlet flames like a caterpillar's cocoon. The thought was an apt one, as I could feel myself being melted down and remade. It wasn't painful, quite the opposite, really. A dozen orgasms, a chocolate cake and a week in a spa surrounded by buff men and sexy women attending to my every desire couldn't even reach the same weight class.

If I could have, I'd be screaming in ecstacy until my vocal cords gave out from how good it felt. My body grew actual curves my puberty had skipped out on. I had tits! An ass worth the name and hips wider than my shoulders.

Then, stranger things happened.

A long and wiry spade-tipped tail coiled around thicc thighs that ended in cloven hooves. My skin turned crimson like a bucket of paint spilled on me. Horns poked out of my silky black hair like a crown and a forked tongue fell out of my fanged mouth, nearly reaching my new tits.

The swirling cocoon of flames spun faster for a few final seconds before harmlessly vanishing in a rush of heat and light.

Sam lowered his crossed arms from his face, hair an unfairly sexy mess atop his head. Our eyes met and a burst of lust and devotion exploded from my core.

I could feel an invisible connection between us. Energy flowing back and forth between my own crimson flame and Sam's...something. Unlike my own inferno, his core of sapphire felt muddled, drained of energy. Instinctively, I knew it was because of me. He'd ignited my flame at the cost of his own energy.

Well, my forked tongue ran along my lips, I'll just have to repay him by helping him charge up~

For some reason, Sam looked nervous as I crawled over to him with my hips swaying and sensitive nipples brushing along the floor.

"Thank you, Master! Thank you for awakening me! I feel so much more alive than before." I crooned with my new sinfully silky voice. My tongue flicked down to slide along his weakly twitching shaft. "We'll have your strength back in just a minute~"

"W-what, what the fuck just happened!?" He stuttered out, scrabbling away for the half second it took for him to hit the wall. "Macy? Are you still you?"

I pouted with my bottom lip trembling. "Of course I'm me!" I shook my tits side to side and waved my tail. "More Me than I've ever been!"

"But..."

The door swung open. "Hey! What's with the light?" Daniel's bulk blocked the doorway on his own, leaving a few other gawkers peeking through at the edges. "Macy, you okay? Nathan and I can throw him out if you want."

I threw myself around my buddy's chest. "Heyyy, Danny~ I'm fine! Sam's just being shy!" I giggled as Daniel's arms supported my new ass, making me wiggle into his touch. "I can play with you in a minute." I pressed my burning lips on his face.

He blinked with a glowing red lip mark on his cheek. Hehe! I didn't know I could do that! "Uh... sure." He grinned down at a gobsmacked Sam. "I'll leave you two alone, come back out when you find pants!"

My friend's strong arms peeled me off and plopped me back down infront of my new Master before he closed the door again.

I spun back to face Sam and resumed my life's new purpose. "Don't worry Master, it'll all make sense soon." I purred with my tail curling into a heart shape behind me.

Sam didn't resist as I climbed atop him and angled his cock to my smoldering pussy. Our gazes met and watching his eyes roll back with the lids fluttering was almost as good as finally having a cock in my cunt that wasn't silicone.

He only gasped and squeezed my hips when his pulsing cock tapped against my cervix as it grew to its proper size. The whirling blue in his soul accelerated after every delicious smack of our hips.

When his glowing blue eyes clenched shut as our souls traded energy until we had balanced out, he merely growled into my mouth. My tongue was nicked by one of his shark like teeth as it grew into place. The oddly spicy taste of my blood only added to the experience.

Finally, Sam's stark white skin was covered by patches of metallic blue scales and his fangs marked my shoulder. My skinny tail coiled together with his thicker, more reptilian one.

I mewled as his massive cock left my gaping hole, followed by a flood of his cum. My Master kissed and nipped his way up to my face. Giving me a fond smile as he pulled back.

"Thank you, Macy. I understand now." His new voice had a sibilant hiss to it that sent tingles of exhausted glee racing over my skin. He cradled my cheek in his clawed hand. I nuzzled into it.

"You're welcome, Master!"

My adoring red eyes met his devoted blue. We spoke without words. With our souls. Agreeing on what to do next.
