Grraaahhh!
>You cry out, struggling against the web restraints on the wall as a set of needle-sharp fangs pierce the nape of your neck.
>A burning pain quickly fills your veins as the teeth withdraw, spreading lower and lower throughout your body and setting your capillaries on fire.
>Above you, a set of soulless obsidian spheres gaze hungrily upon your naked form; clothing torn away by nimble tendrils and claws.
>Your assailant grins, dripping venom of arousal onto violet fur.
>Far more monster than pony; the hooked spindles of her spidery legs sprouted from along the spine, supporting a sickeningly thin earth pony body uncomfortably close to yours.
>Your nose fills with the smell of burnt lavender and ash.
>You start to pant , feeling inexplicably warm as the intruder begins to laugh.
>"Hahaha~ now you will be mine...and ONLY mine."
>The home invader coos, caressing your cheek with a slender pony hoof.
>"I warned you about resisting..."
I refuse to be taken advantage of by a virus!
>"You don't have much of a choice, darling."
>Soon you feel her vile venom creep into your lower stomach, nearly making you ill before moving into your sex.
>Against your every effort, your manhood rises into the air and throbs with a burning need for release. 
>She lowers herself with her spidery appendages to get a better view.
>Just her breath against your head is enough to make you groan; the world spins around you as you develop tunnel vision.
>"My, my...what an impressive breed you are. So thick, so long, so,"
>She takes a sniff of your shaft.
>"...fertile."
>She finishes with a growl.
I'll never love a monster...
>You mumble out in both pain and lust.
>"Doesn't mean you can't father a brood. You have such a lovely, secluded home to harbor our future family, my dear. You will be a marvelous father for our viral clutch..."
>Moving her pony appendages out of the way and using her spidery legs, the virus slides her scrawny bodice against you, revealing an ebony marehood.
>Her sex drips a disgusting greenish-yellow fluid slowly onto your legs and scrotum, indicating her perverse arousal.
>A musk begins to replace the smell of ash inside your nostrils.
>You manhood only throbs harder.
No...I'll never...No!
>You cry out, throwing your head to the side.
>"Yes you will, my love."
>She hisses in reply, lowering her squelching, winking marehood closer and closer to your crown.
>You clench your eyes, and resign yourself to your fate.
>BOOM!
>The wall across from you explodes with a rainbow spectrum, sending dust and debris everywhere.
>"Not so fast, you filthy virus!"
>An adorable voice squeaks from the rubble.
>Your would-be rapist flies back from the force, crying out in shock as the smoke settles as you both observe the new face.
>A pair of narrow eyes look on the scene with confidence, hidden behind a thin Zoro-like mask.
>"Windows Defender!? No!"
My hero!
>The foalish superhero stands proudly, a set of tight red polyester spandex snug against her light-blue fur.
>A small yellow shoulder cape, emblazed with the letter "D", flaps cutely in the open breeze.
>"Now, get out of here before I squish you like the bug you are!"
>The virus rises, hissing violently before charging the young filly.
>"Not before my groom fertilizes my eggs!" 
>Narrowly missing the attacking claws, Windows Defender dodges each spidery leg.
>"Windows Smart Screen, go!"
>The unicorn horn, sprouting from her dark-blue mane, begins to glow with an intense light.
>In an instant, a swatter-like screen slams against the virus, sweeping her up and squeezing her painfully.
>"Nggaahhh! Nooo..."
>She groans in agony.
>"Now, back to the deep Everfree from whence you came!"
>With a flash of her horn, the foal pixilates your wailing assailant off into nothingness before another peep escapes her lips.
Th-thank you...
>You gasp, heart racing from both the excitement and the venom.
>"All in a day's work, 'sir'..."
>She giggles softly, trotting up to you.
>"Oh no! You've been bitten!"
>She points out, a little too cheerfully for your taste.
Yes I was...
>You blush in embarrassment with Windows Defender being shadowed by your thick erection and swollen testicles.
Can you let me dow-
>"Well there's only one true way to remove the potent effects of a virus' venom, and it cannot be accomplished easily or alone."
>She cuts you off, lowering her head before giving your well-defined ridge a playful lick.
>You moan in confusion as she takes you into her mouth and suckles longingly on the head.
>Before long, a small stream of precum leaks out into her thirsty mouth.
>She pulls her lips off you, her chest rising and falling with deep breaths.
>"My scan shows you are positively overflowing with the effects of venom! When was the last time you were 'cleaned out'?"
>She chides teasingly before turning around, moving her tail to the side.
What are you doing...?!
>You pant while flexing against the web restraints, the world spinning once more from the lusty sensations flowing through you.
>With a thum of magic, the young heroine makes a lengthy rip in her tight red spandex to reveal a winking, azure marehood of her own.
>"Performing an in-depth cleansing, silly." 
>She coos, squirting a modest amount of filly juice onto your head and shaft before grinding it against her moist lips.
>"The 'D' doesn't just stand for 'Defender', Anon."
>She whispers inaudibly to herself, smiling in anticipation.
>You hiss, grinding your teeth together as her rocking hips slowly force your aching head inside.
>"Oh DOS, you're big..."
>She groans, dilating her marehood in a futile attempt to allow you deeper.
>Her muscles contract, pulling your glans by the ridge centimeter by centimeter further inside.
>You knock your head against the wall, unable to endure such pleasure as the venom still burns within.
>Eventually, the filly begins to rise and lower herself against you, rocking back and forth.
>"Mmm...just relax, 'sir', and let me take care of everything."
>Lewd slaps fill the room, mixed with the cries of the filly as she breeds you.
>Lost to the sensations of sex, you can only moan out garbled attempts at questions.
 >However, you are drowned out as the foal screams into the air, arcing her back clenching almost painfully against your shaft.
>A river of light-yellow marecum flows readily against your legs, mixing with her sweaty fur as her whole bodice quivers.
>The smell of hay and musk fills the air.
>"L-looks like *ah* you have quite the stubborn load..."
>Windows Defender pants, still shuddering around your half-buried cock splitting her in two.
>Slowly massaging your length with her marehood, she flexes her slender muscles underneath the spandex as she milks you; the glint of the light contrasts against the colors of her small cape.
>You tighten your jaw, feeling the venom light your brain up as your seed rises through your shaft.
>"S-so deep..."
>Hyper-sexed, you buck your hips against her in an attempt to knot yourself deep inside the sexy heroine's womb.
>She feels you getting closer, and quickens her vaginal massage.
>"Yesss...let it all out inside; it's the only way!"
>She moans with a squeaking voice.
>Without a second thought, your body shudders as you mind goes blank.
>Thick, heavy spurts of cream explode into the young mare's very core.
Ahhh!
>You nearly scream, but can only manage gasping for air as one of the most powerful orgasms of your life overtakes you.
>Made hyper-sensitive by the venom, your testicles can only contract and contract while you flood the foal's shallow basin.
>"Yes Anon, fill me up,"
>The masked filly grunts to herself.
>"Make me pregnant..."
>You groan lewdly into the air as your bountiful load finally tapers off.
>With a sigh of pleasure, the foal manages to slowly dislodge your aching glans from her womb.
>She turns around on quivering legs, only to gasp in surprise as you remain rigid in the air.
That...that was...oohhh!
>You're cut off once more as Windows Defender plants her lips firmly against your crown, sucking up your dripping seed.
>The foal grins devilishly, her still-winking marehood leaking white streams.
>"It looks like we have a long afternoon ahead of us coaxing out all this venom from your system..."
>You gulp, lowering your head and resigning yourself to further "scanning".
>The filly giggles once more, a blush spreading from out underneath her mask before lowering her head. 
*************************************************************************************
>Later that night, you work on repairing your wall, half-exhausted and sexually drained.
>Your OS filly, Windows Eight, wobbles inside the door on shaky hooves while floating a large bag of delicious carrots.
>"Wow, what did I miss?"
>She scans the room lazily.
>"Let's just say that I'm buying us a new firewall for when you're out picking up groceries again...where were you all day? Are you alright? You look wobbly."
>You ask, putting down your tools and taking the carrots from the air.
>"Oh I, er, just tripped while levitating all these carrots home. Whew, I'm beat! I'm hitting the shower before powering down for bed. Night!"
>She states hurriedly with a smirk before quickly trotting to the bathroom.
>As Winnie passes, you can't help but smell a strong hint of musk and sweat.
>You shake the thought from your head as your stomach grumbles.
>Ah well, it looks like you'll be having some tasty carrots for dinner at least.
