Smutty Kibbles Growth.

You see her sitting in the corner of a tavern, hunched over. She’s covered up mostly by a cloak, although her immense tits are resting on the table in plain sight covered in a damaged blue robe. There’s a rough split between them, white fur sprouting from within. She’s also breathing hard, fingers gripping the table ledge. Going by her short muzzle and lolling tongue, she’s a dog fera.

You notice this and can't help but worry. You stand and head over with your ale in hand. You’re a big, muscular horse fera. Farmhand, pretty much the strongest guy there so you do all the lifting.
You're not that big in gloating terms despite your seven foot frame. You’re a pretty modest, hardworking guy. Just no gf because you’re...well...too big.

Blessing and a curse, as they say. Your biggest gf would be too sore after a few minutes of screwing.
Any pants that fit you always cause an absurd bulge. An old teaser of a girlfriend would make a game of making you ruin your trousers by getting you turned on in public. Another joked she should give you a trigger phrase if you're ever held your hands up at knifepoint and need a third 'fist' to punch someone.
It was all good practice at keeping under control though. More than a few other feras near the dog girl are covering their laps and despite the absurd womanly frame on her, you're in control and calm.

You finally reach her. She’s just focusing on a mug of water in front of her.
You ask if she’s okay. She yelps and twitches, then looks at you. Her green eyes under the hood lock onto yours, then they slide down to your groin. Her eyes go wide, she blushes and the edges of her mouth creep up to a grin for a moment.
She tries to tear her eyes away, but gives a heavy moan before bringing her hands over her face to force herself to stop staring. She seems to move in her seat, but she hasn’t changed position. You blinked and missed what she did.

She calms slightly and says she’s fine. You sit down opposite her, and she grabs the mug, guzzling the water. You sip your ale.
You tell her you can find a healer if she’s unwell.
She tells you she is one, kind of, but she’s fine. She’s got a ‘thing’ and it can’t be cured with magic. She seems to calm down a bit, pulling back the hood.

She’s got a full head of orange hair, white furred face with a brown patch around her left eye. She’s cute. Somewhat ‘heavy’ as well judging by the pudge beneath her ridiculous tits. You can’t help but stare for a moment before you refocus. You want her to calm down so you indulge in small-talk
You say that her being a mage is impressive, and there aren't many of their type around this town. You say it's impressive someone as young as she is travels alone, she must be pretty powerful. She seems touched by the compliment and you stare at each other for a moment, and blushes again. Then she gasps and shivers.
You watch as her head creeps higher; like the last time she 'moved', only now you know she's growing.

You can't help but stare. Her already obvious cleavage tears wider. Several other rips sound off from her as she brings her arms down to pinch her cloak around her front. She then looks around and tries to slouch down, blushing and hoping nobody noticed that.
You tell her she’s obviously not alright. You beg her to let you help her.
She whispers that she was a healer, but found a knack for macromancy, size magic. She dabbles in all kinds of spells, but she mostly goes around helping people by altering sizes. Bigger food, shrinking obstructing boulders, growing beasts of burden for difficult jobs and such.

You say that explains the growth, but she doesn’t seem in control.
She blushes even more. She says that she uses macromancy so much but sometimes gets tied to other aspects of her life.
She gives an example of a time she grew two miles tall from a flu. You’d heard about that. Or the time she ate a growth enchanted fruit and nearly crushed a village. You didn't hear about that one, but she doesn't surprise you. She mumbles about a time she nearly flooded a town or outgrew the world, but you're getting worried she's delirious.

You ask if she’s sick now.
The dog girl glances about, then leans towards you. You can barely hear her and lean in yourself.
She tells you she’s not usually this loose, and she apologises in advance but she bluntly asks if you want to help her....to fuck her out of this condition. You spit a mouthful of ale on the floor.

She growls and says she’s somehow been hit by a heat, a rare condition, and it’s piggybacking on her growth magic. You seem real nice and that the sooner she scratches her ‘itch’ the sooner she won’t be at risk crushing a city under her ass just by accidentally thinking of having sex. It might as be with someone who actually seems worried...and is attractive....and sturdy.
You immediately realise you haven't had your itch scratched for a while either, she’s delightfully soft, shapely and plush and you’d be helping her out.
You tell her that if she’s completely sure then who’re you to decline?

She smiles and stands. She’s as tall as you are now, seven foot. Her clothes are full to bursting.
You ask if she has a room.
She giggles and says that for what you’re gonna be doing, you don’t need a room. Even a barn won’t be enough. She hopes you’re okay with public exposure.
You say you’ve got a reputation already thanks to that pant shredder girlfriend, then stand and shrug. It's been a weird goddamn day already and it's not gonna stop you helping her.
Her eyes once more narrow into your crotch. She licks her lips, gasps and swells another foot taller. She’s probably gonna be naked if that happens again.
She tells you best get going.

You follow the dog fera, she’s having to pull her cloak around her pretty tight as small shreds of her clothes fall from her. Her sandals snap off her feet and she grumbles. With the cloak only reaching her thighs you see her leggings are filled with holes. White and brown fur spilling out on top of thick, plush flesh.
Once outside the tavern, you walk beside her, doing your best not to stare at her jiggling tits and the subtle wobble of her soft belly through the cloak. You suddenly realise you don’t even know her name, and vice-versa. You tell her.
Anon meet Kibbela, Kibbela meet Anon. She tells you to call her Kibbles though

You’re surprised she hasn’t been approached before, you say she’s really pretty.
She has. But the last guy got a handful without her consent burst into flame for his trouble. You give her a worried look, she winks at you and says you seem like a genuinely nice guy. She looks you over, eyes lingering on your brawny arms and chest and she licks her lips again.
Kibbles gasps and her clothes shred loudly. Her cloak now at her hips, barely covering the nine and a half foot dog girl. She’s still growing and is about to get fully exposed. You do the gentlemanly thing and stand in front of her as you drag her down an alley to get out of sight. You’re at the edge of town thankfully, a short few paces from the plains around the town.

Kibbles closes her eyes and grunts, trying to stop the growth but it’s a lost cause. She tells you she needs you NOW.
Her swelling tits sheer through the overspent cloak and bury your muzzle in the soft, warm mass. She pushes you against the opposite wall and you’re smothered.
You have some ripping of your own as your as your pants split as your control is finally spent. Kibbles gasps as you feel your massive shaft slaps against her ass between her legs, hotdogging it and bumping into the underside of her bushy tail. The plushness of her furry cheeks is amazing. You have just enough control to push her gently back, grabbing her hand and running away from the town.

You get as much distance as possible as she continues growing. She eventually pulls you off the ground and runs for the treeline. Kibbles buries you in her tits as she gasps and moans, growing taller and wider.
She eventually collapses onto her knees, and puts you down. Her face is fully flushed, and her eyes are lidded as she stares at your erect length. Even you realise that she's some twenty feet tall. For the first time in your life, you feel inadequate.

She tells you to hold on, and she summons a staff to her hand. A long thing with a green, double pronged tip. She taps you with it before unsummoning it in a flash of green light. You feel something creeping its way into your body. With a firm shudder, you feel your shirt and the remnants of your pants draw tight. You're growing as well.
Kibbles presses a hand onto your chest and pushes you to the floor, and slowly slides your length into her dripping snatch. She gasps and you respond with a low grunt. Then she slowly presses her weight onto you slowly and you almost laugh as you realise you haven't been in someone up to the hilt in years.

Your clothes fully peel off and Kibbles starts rocking against you. She's got to be some thirty feet tall to your ten. She seems a little frustrated and summons her staff once more, casting the same spell and you groan as you swell in size against her. She even yelps as you suddenly fill her and she has to lift herself off as you overwhelm her. You're now both thirty five feet tall, and she's got absolutely no hope of taking you.

Kibbles can't help but look at your colossal length and looks back at you. Her still present heat flares; she starts drooling, moaning and she grows larger in a big, twenty foot burst, and you have the wind taken out of you as she thrusts down onto you once more. She builds a solid rhythm, slamming against you and you can feel the earth is shuddering from her massive weight. Her tits rhythmically bounce about and her soft belly shudders and jiggles. You can feel her ass wobble against your legs as the perfect amount of fat on her drives you wild.

You're still slowly growing, but so is she; yours is steady and even as you hit forty feet tall, but she's spasming larger in bursts, now at sixty. You're catching up as you feel her slick insides clenching against your vast length. Her already aroused state pushes her ever closer to the brink, and you're only just getting warmed up, but she climaxes anyway with a final slam against your hips. Kibbles howls skyward and her femcum gushes over your length, then she flops against you, smothering you once more in her amazing plush body.

She gasps for breath and stops growing, then shrinking. You don't have the brain power to warn her before she gasps with pain as your still growing body once more threatens to hurt her. You drag her off of your length and she collapses onto your chest as she dwindles further, returning to her normal size buried in your sleek chest fur. She's absolutely tiny compared to you.

Kibbles apologises for not getting you off as well, and begs for a few minutes to recover.
You beg back that she hurries, because the edging is fading and you'll be forced to punish her. She gives you a worried look but then smile down at her and say you're joking.

She grins back, and once more summons her staff. With a cast of the same spell she's used on you, she rockets back up in size, only to stop growing some forty feet tall. She tries again, then realises and confesses she's been so wrapped up in her heat growth that she's a bit short on magic right now. Her staff vanishes and you think as deeply as your lust addled brain can.
You say it's time to improvise as you reach seventy feet tall.

You grab her gently and bring her against your length. She giggles as you feel her wrap her arms, tits and legs around your length and you begin using her as a sex toy. She licks as she's pumped up and down, and you decide to change positions. You rock yourself on your side and slide your knees beneath you, and start pumping her against you as rapidly as you dare. Her slightly ticklish, soft and amazing body soon brings you up to the edge once more. Her whole body is plush enough to conform to your length and you shiver as the pressure builds in your groin. It's been a long time since you last came, and with almost perfect dramatic timing, you stop growing at eighty feet tall and suck in a breath.

With a loud neigh, you cum so hard you knock the bark off a tree with the ejaculation; you spray the forest with a series of violent eruptions, and you release Kibbles. She watches the scene with amazement then back to you. You grin and then turn your still cumming cock to her, and with a fairly weak final spray, you hose her down onto the ground.

She coughs and looks her soaked self over as you finally feel the post orgasm weakness seep in, and slump as you catch your breath.
She calls you an asshole, but even then she can't keep a straight face and laughs. You chuckle and ask if she can shrink you back now. She brings her staff up and with a great deal of effort, she touches your knee then herself and you feel yourself finally start shrinking.

It takes a while, and Kibbles reaches her normal height first, but you stop shrinking and stand.
For some reason, Kibbles is only as tall as your hips. You ask what's going on.
She's in deep thought for a while, then facepalms.
Kibbles tells you that her heat and growth bond might have meant that when she orgasmed, she ejected a sizable chunk of magic into you as the 'permanent' magic was broken inside her. She could shrink you temporarily, but you're now stuck at eleven feet tall as your natural height.

You shrug and say you were a heavy lifter around town anyway, maybe it won't be so bad getting the usual jobs done in a fraction of the time.
She responds with an offer; she could use a heavy lifter and a bodyguard herself, especially if she happens to come down with a heat again she'd have someone with...experience. She blushes and also says she could see herself maybe pushing from an employment offer to something a little deeper. You've only just met, but you admit you're interested.

You pick her up and tell her you agree, then kiss her. It's time for a change of pace.
You head off, wash yourself in a nearby lake (with help of her magic; she's pretty sticky), and you feel like it's going to be the start of an interesting adventure.
The End.
