Chapter 0 - [TF, F/F] More than a class change

You cannot believe your luck. You’ve always liked big girls, and they don’t get much bigger than Heliana the adventurer. She’s 8 feet of amazing, with a big doofy smile, a big, doofy personality, and tits you could literally drown in. She’s been sweet on you since you met on the road last week, and now she’s openly groping you in the common room and whispering sweet nothings in your ear. You can’t quite make out the words, but you think you get the gist of it, because it’s set such a fire in your loins that you can hardly think.
When she finally gets up and asks you to follow her back to her room, you spring from your seat and your tablemates cheer loudly, happy that at least one of you is about to have a good night.
By the time you get to your room, something feels off. Your head is swimming. You’ve been drinking, yes, but not this much. It doesn’t matter, though. Heliana is stroking your chin and telling you to get naked, and that’s the only thing you care about.
She too begins to undress in front of you, slowly revealing her glorious body.
Her big, friendly cow face has been there the entire time, but the sly smile is new and very cute. Her breasts are round and perfect. Her soft, furry tummy is extremely kissable, and her powerful thighs would feel so good around your neck.
The only thing that gives you pause is when she pulls down her breaches and her massive penis flops down between her legs. It’s easily as thick as your arm, and hangs down all the way to her knees. You’ve always been open to the idea of dating a woman with a dick, but this dick could kill you.
She sees you staring and smiles reassuringly.
“Don’t worry, sugar,” she says. She approaches you and runs her fingers through your hair. Her touch sends jolts of pleasure shooting through you like lightning. “I’m not gonna put that in you.” She leans in and whispers: “Not until you’re ready.”

Before you can ask what she means by that, she pushes you down onto the bed, kneels in front of you, and kisses you on the mouth. It’s strange, but not unpleasant. Her soft, insistent mouth is so much bigger than yours, and though she can only fit the tip of her tongue into your mouth, she seems to enjoy watching you choke on it. Her hands are on the inside of your thighs, and when her thumbs brushes towards the sensitive skin at the edge of your groin, it feels so good you think it’s gonna drive you insane.
Your entire body is on fire now, full of a wild desire you didn’t know was in you. Your cock is twitching and your entire body is shaking, but Heliana seems to be in no hurry. She slowly plants soft, wet kisses on your cheek, your neck, your collarbone, traveling down your body until she gets to your nipple. She hovers over it, practically drooling, and you notice how sensitive it’s become. It’s much bigger than it used to be, so puffy and swollen that just her breath against it has you squirming and pleading. She looks you directly in the eyes, flashes a sadistic smile, puts your engorged nipple in her mouth, and sucks.
The sensation is so intense, for a second you think you came. But your cock is still only dripping with precum, and the feeling never stops. Heliana keeps happily sucking on your nipple, letting it pass in and out of her mouth, running her tongue over and around it, squeezing the base of it with her hand. Just when you start to think you’ve gotten used to it, she grabs your other nipple with her free hand and squeezes, reducing you once again to a screaming, thrashing mess. You beg, and you buck, trying to rub yourself on her, or the bed, or the doorpost, literally anything, just to achieve release. But she effortlessly holds you down and keeps sucking.
Only when you’ve stopped fighting, when you’re just laying there trembling and crying, does she stop. Only once you’re still does she begin to move down your chest, kissing your belly and licking your navel, until finally, oh god finally, you can feel her hot, hot breath against your quivering dick.
“Please,” you beg. “Please let me come.”
“All right, sugar. But only because you asked so nicely.” She kisses the head of your cock playfully, and you are once again amazed you don’t come on the spot. “Suppose it’s only right we give this little guy a proper sendoff, anyway.”
Once again, before you can ask what she means, she goes on the attack. She swallows your entire manhood and, once again, your brain is on fire. The suction is incredible. Her juicy lips have a deathgrip on your cock, and her tongue is playing over and around your head as she sucks.
You can’t stand it. You can’t stand it, and you can’t hold back any more. It’s time to fulfill a boyhood dream.
Your arms shoot out and grasp her magnificent horns with the white-knuckle grip of a drowning man clinging to a lifeboat, brace against the bedframe, and fuck her big, pretty mouth as hard as you possibly can.
Heliana loves it. She eggs you on with delighted moans and her hands reach out beneath you, supporting your hips and guiding you in and out of her. Her touch, her sensual moans, her powerful tongue, it’s all far too much. You come, and every nerve ending burns. You think you scream, but you’re not even present enough to know. For you, the only things that exist are Heliana’s warm, welcoming mouth, and the earth-shattering orgasm. She swallows while you’re still in her, letting you feel the working of her tongue. She keeps sucking long after the orgasm has passed, pumping you with her lips and tongue, greedily milking every drop of cum out of you. It’s probably the exhaustion playing tricks with your head, but when your limp dick finally falls out of her mouth, it looks a lot smaller than you remember.

You lie back, panting. Your head is spinning. The bedsheets feel different. They cling to your skin oddly. You look down across your body, and you see it’s discolored and misshapen. Dark green patches are spreading across your limbs. The skin seems cracked, scaly. Your puffy nipples are rising on much bigger mounds of flesh, and your hips are becoming very pronounced.
“What’s happening?” you say, your voice weak, unable to muster any greater concern than that.
Heliana gets on top of you. You squirm as the soft weight of her breasts rubs across and settles over your sensitive nipples, but she pins you effortlessly. Gods, she smells so good. Like fresh milk and warm hay. You’re rock hard again, but something about your dick feels very different.
She nuzzles your beck, tickling you with her big, soft nose. Her hand plays across your mouth, parting your lips and playing with your tongue. Your teeth feel weird, like they don’t fit in your mouth right.
“I’m fixing you,” she says pleasantly. “I want to take you with me, but a scrawny little human could never survive the places I’m going and the things I’m doing.”
She grabs her monstrous dick and slaps it playfully against your bulging belly.
“Frankly, I don’t think you could even have survived me.”
She plants big sloppy kisses on your neck, plays with your growing tits. Her touch feels amazing. Everything feels amazing.
“It’s just such a shame,” she mutters. “I wish I knew a better spell. Gators are great in so many ways, but they’re not especially sociable, are they? They don’t even pair bond. They’ll tolerate just about anyone, but I don’t need a fair-weather friend. I need a partner.”
She looks at you, eyes overflowing with love. You feel something dark inside of you, something that is decidedly not love.
“But don’t you worry. We can modify the spell in real time, it just takes a little elbow grease.”
You are so angry you can barely contain it. Except - no. It’s not anger. It’s a dark, violent impulse, but it’s not anger. It’s something far older, and far worse. When you look at Heliana now, you see only meat.
Her hand snaps out and grabs you by the snout. Your body has grown and strengthened so much, but she’s still so much stronger than you. She forces you to look in her eyes, and for the first time you can really see the mad delight in them.
“There it is! In your eyes! There’s that antisocial tendency we’re gonna have to breed out of you.”
She reaches towards your crotch, tracing her hand down your fat tits and plump stomach. Just as she’s about to reach your cock, you realize with a start that you don’t have one. You’re still unimaginably horny, but your hard cock has been replaced with a dripping pussy. The warm slickness sliding down your taint feels so good it makes you drool with anticipation.
Heliana slides one of her thick fingers inside you, right up to the knuckle. She encounters no resistance, and you can barely even feel it.
“More,” you beg.
She kisses you on your adorable little snoot and shoves another finger in.
“More.”
She puts in the third and fourth. You’re actually feeling something now, but it’s not enough. Even with almost her entire hand pressing into you, it’s not enough.
“More.”
She pulls out, her fingers slick with your juices.
“I think you’re ready.”
She lets you go, but you can’t even think about moving or resisting. The only thing you want, the only thing that matters in your life, is for her to plow you senseless. You spread your legs as wide as they’ll go, stick your fingers in your vagina and hold it open for her.
“Please.” It’s all you can say. “Please.”
“Don’t worry, sugar. I will.” She looks down on you, admiring your body. It’s almost finished; your skin is tough, your limbs are strong, and your shape is divine. You just need to get a little bigger, a little stronger.
“Now, sugar, I’m afraid this next part’s going to get a little uncomfortable. I have to hurry before the spell is finished, so just try not to panic, okay? If you take a deep breath and try to relax, you might even enjoy it.”
You don’t know what she’s talking about, but you know what you want. You lift your hips off the bed, thrusting your waiting pussy towards her, begging her to use you.
“Please.”
She chuckles pleasantly.
“All right sugar,” she says as she puts the tip in. “Buckle up.”
She shoves her cock - her entire, enormous cock - all the way inside, knocking the air out of you and sending your fat thighs jiggling with a loud smack. Even as you’re wheezing and hacking and convulsing, she rears back and slams back into you again.
This shouldn’t be possible. As big and wet and deep as you are, this should not be possible. But you can feel your body warping and distending to make it possible. Every time she thrusts into you, your insides twist around her, giving her more spaces where she needs it, squeezing tighter where she doesn’t. With every thrust, she fits a little better. You suddenly understand what’s happening: she’s claiming you.
“Oh fuck, sugar,” she pants. “Your pussy is amazing.”
She’s found a rhythm, and you’re finding time to breathe between strokes. You watch her breasts swing back and forth as she pounds you, and suddenly you’re just as hungry for her touch as you are for her cock. You spread your arms wide, pleading for her embrace.
When she sees, her smile is like the sun. She lowers herself into your arms and kisses you.
She fits much better now. Her fat tits rest comfortably on top of yours, and your soft tummy gives her excellent support as she continues to pound you. Your fat tongues each fit comfortably in the other’s mouth, and soon you’re panting and moaning as you lick each other inside and out.
Heliana breaks out of the kiss and buries her face in the crook of your neck. She secures her arms around your neck and, the next time she thrusts, she presses her whole body into you. She’s trying to get even farther inside you, but she was already balls deep.
“Ah, fuck. I can’t believe you’re taking it all,” she pants, then kisses the thick folds of skin around your neck. “You’re such a good girl, sugar.”
Something comes over you then. Some half-forgotten memory from the distant past.
“I-I’m not,” you stammer. “I’m not a girl.”
Heliana raises herself up and looks at you quizzically.
“But you are, sugar.” She leans down and kisses you softly on the nose. “You’re my very good girl.”
She’s right, of course. At this very moment, you have almost three feet of bull cock inside your hungry cunt, and your curvy hips are desperately straining upwards, trying to fit in even more. Your tits are huge, and soft, and provide a perfect counterbalance for your shapely butt. Your shape is just right, the kind of perfect muffintop hourglass that people can’t help but want to sink their hands, faces and cocks into. Even your moans, deep and guttural as they’ve become, have a certain feminine softness to them.
Yes, you are a woman. What’s more, you want to be a woman. You want to be her woman. And when you look into her eyes, you know that’s how she sees you. She’s licking her lips, drinking you in, basking in the knowledge that this perfect specimen is her woman. Her very good girl.
Heliana’s breath starts to grow shaky. Her adorable little moans are taking on a desperate, almost pained character. When she takes a deep breath, and looks you in the eyes, you know what’s coming.
“I’m really close, sugar,” she whispers. “When I come in you, that’s it. The spell is finished, and all of this is permanent. You’ll be this, forever. You’ll be mine, forever. Do you want that, sugar?”
As if she even has to ask.
“Yes!” you practically scream. “Yesyesyesyes! Please, oh god, please make me yours.”
She gives you the happiest smile you’ve ever seen, and leans in for another gentle kiss of your nose.
Then she leans back on her knees, makes herself comfortable, and grabs you by the waist. The true waist, just below your breasts. She knows what she’s doing. This hold accentuates your figure, makes you think about her hands straying up to your breasts or down to your hips. She’s already turned you into a woman and made you feel like a woman. Now she’s going to fuck you like a woman.
She goes hard right from the start, slamming into you as fast as she can, over and over and over. You’re almost back where you started, paralyzed by her cock, but this time you’re prepared. You’re relaxed. You play with your tits, postilion yourself for maximum penetration, and allow yourself to just make whatever filthy noises she can pound out of you.
Your moans spur Heliana on, and she somehow picks up the pace even further. She too is making base, guttural sounds of impending pleasure, and hers spur you on as much as yours did her.
You feel her cock start to twitch, and suddenly she’s on top of you, shoving you into a mating press. Her tits are in your face, her cock is deeper in you that it’s ever been, and she’s braying with pleasure directly into your ear. And then the orgasm comes, roiling and all-consuming. You entire body tenses as if struck by lightning, and you throw your arms around her and scream her name.
Heliana responds in kind, screaming and tensing as you clench down on her cock and her cum begins to flow. The sheer volume of it catches you off guard. It fills you up and stretches you out, bulging out your stomach, and still it keeps coming. It keeps pumping and pumping, and Heliana keeps grunting and panting and thrusting. It fills you to the brim and still it keeps coming, spilling out of your cunt and soaking the bedsheets. If you weren’t already in the middle of an orgasm, you would come again.
When the final, shuddering blast finally comes, she kisses you so hard you’re afraid she’s going to cut herself on your teeth. But she just smiles at you, pulls her dick out with a wet ‘plop’ and collapses on the bed next to you, shaking and panting.

And, just like that, you are yourself again. Your new self. Your head isn’t swimming, and that burning, painful desire is gone. You look down at your beautiful wife, and feel only that ordinary ember of lust in the back of your mind. It’s not strictly accurate, as far as your understanding goes, but that’s the word your brain has chosen to label the feelings you have for her, the bond she’s created. “Wife”.
A few silent minutes pass before Heliana reaches out and touches your arm.
“How you doing, sugar?”
You lay down besides her.
“Good. Great. Better than ever, I think.”
She puts her arm around your waist, pulls you close, kisses you softly but passionately. You feel her warmth, and the smell of her cum wafts towards you, and the ember burns a little brighter.
“You need a new name, I think.”
That’s odd. You must’ve had a name, before. But you can’t remember it. And frankly, you don’t care to. It seems terribly unimportant.
As does picking a new name. But Heliana seems to think it’s important, so you might as well let her do it.
“Give me one.”
She seems to think for a moment, but you’re pretty sure she already had one picked out.
“I think I will call you Lily,” she says, and presses herself against you. “My beautiful, blooming flower,” she whispers. She kisses you deeply, her tongue playing along your sharp teeth, and her hand slides up to play with your breasts. Her dick is starting to press against your legs, begging to be let back in between them.
You truly cannot believe your luck.
