Counter terrorist otter

some terrorists have unleashed a de-evolution virus into society
it's the usual 'humans turn into cavemen' thing, and those are the lucky ones
others end up as apes
have a trim otter gf
brightest little bubble of energy in the world, super loving, super intelligent
just...y'know, slim and tiny
she's also part of the counter-terrorist enforcement that shut down these attacks before it got too far, with maybe a hundred afflicted and even a cure in the works for the victims
world saved thanks to her and her team, and the other cells of the counter-group worldwide
too bad when it came to disposal, someone accidentally gave her a compromised cleansuit
which you only discover during a bout of celebratory sex
her 5ft 1/4 inch self groans and writhes as her muscles balloon under her sleek fur
and the bed groans
there's a feral edge to her eyes as she grows so big the bed gives way
and not just raw size; her tits go from palmable to head-smothering
her thighs and ass grow from piggy-back ride to that one Squidward pic with the flattened face
suddenly your tiny gf is now a fifteen foot behemoth filling the whole room
you do your utmost to soothe the savage beast
basically you end up being used like a willing dildo
you pass out several times during your brave and totally consensual pacification of your now dumb-as-rocks gf
she fucks you until you're both spent, but you manage to grab her phone as she snores so loud the ground quakes
and, thankfully, you have her contacts on speed-dial
they're quick to mobilize, contain and attempt to cure your gf
but it's still experimental
as evidenced by the fact that, at first, nothing seems to happen
but when she wakes up, she's lucid and as smart as she ever was
just, y'know, still fifteen foot tall and a couple of tons heavy of curves and muscle
the team apologizes
you put on a brave face at how 'disappointed' you are until they leave
and snu-snu all over again

otter gf is shocked to discover the anti-terrorist group now wants her on the front line
she’s still your geeky gf, even if she can now deadlift a cement truck
and your admit, you’re a little worried
she’s never been a fighter
but she’s been ‘cured’, so she does make a perfect candidate for chasing down any terrorist remnants
since she should be immune to further doses of the de-evolution virus
so when a group decided to attack nearby, your gf was mobilised
the terrorist cell didn’t anticipate a 15ft otter and fled
she kept up with their escape van, but she was a bit too bulky to catch them without serious collateral damage
so she leapt, her ultra-powerful thighs cratering the street
she aimed to land in front of it and bring the van to a controlled stop
instead she crushed the van under her huge weight
she also got smothered in the terrorist’s anti-evo virus
her body reacted immediately
the imperfect cure resisted it, but didn’t make her immune
as your gf clutched her head and cried out that she couldn’t think straight, a terrorist survivor climbed out and shot at her
and that was it; the fear of being shot, the anger at the pain, the fight-or-flight response…
she turned feral again
and she grew
and holy shit, did she grow
her shoulders crashed through the nearby apartment rooftops
as did her hips
and her truck-sized tits
with a roar that shattered the glass of everything in a half-mile radius, she slammed her foot down on the idiot that shot her
which collapsed the nearby buildings and could be felt the next city over on the Richter scale
you were called in as backup
again, your talent for surviving being shoved up your gf’s slit was in high demand
and another dose of the cure was administered
it brought her down to size
mostly
let’s just hope they refine the cure next time she gets dosed with anti-evo virus
because your 20ft otter gf now slowly grows when angry
