TwilightxFlash NTR

>you return home to Twilight's library
>hear noises upstairs, probably Spike
"Twilight, I brought your groceries and stuff"
>no response, sound is some rhythmic thumping, probably Spike walking around
>you head upstairs, holding groceries because no place to set down
"Twilight?"
>the door is ajar, sounds getting louder
>you barge in, see Twilight bent over on her bed, Flash buried inside her
>she looks up at your voice, and her wings spreads as she sees you
>Flash looks up, a smug grin on his face, his cock buried inside your waifu
>he ceases his thrusting, as you drop your bags in shock
>"Anon!"
>she moves forward, trying to get off of Flash's dick
>his hooves hold her ass in place, and she gives up
>"It's not what it looks like!"

>you're speechless
>Flash takes your silence as acceptance and begins humping again
>for a few moments the only sounds are his grunts and Twilight's moans
>and the sound of their flesh pounding
>Twilight takes a few seconds before, moving a hoof over Flash's
>"s-stop~"
>he doesn't, but you can hear his thrusts slow
>you feel betrayed, humiliated, destroyed, rage
>and a mix of arousal
>which Twilight immediately notices
>"i-is that a boner, anon?"
>her words are interspersed with gasps and moans
>what the fuck?
>you suddenly realize you've had a massive boner all this time
>while some stallion was rutting your mare
>Twilight's shock turns into a seductive smile
>she giggles, laughs at you like some betafaggot

>"You like this don't you?"
>she pulls you closer with her magic
>you notice the glow pulsating with every thrust
>you're pulled by the belt towards her
>and stop before her, and you can clearly see the details of their fucking
>you can see Flash's sheath exposed as it thrusts in and out of Twilight
>Twilight's panting hard as she works her magic on your pants
>freeing your shamefully erect dick
>you're still in fucking shock, and absolute disgust
>Twilight doesn't seem to mind, taking your dick in her hooves
>she laughs at you again
>"I didn't know you were into this, Anon"
>you can only look away in shame
"s-stop fucking her"
>your words are weak, Twilight's working hooves persuading you to give in
>Flash looks at you in the eyes as he's fucking your waifu
>you can't help but look away in shame

>"Don't be like that, Anon, he's a good friend"
>you don't know how she managed a coherent sentence being fucked like that
>every single thrust draws a hot breath from her, as she breathes onto your cock
>everytime your mare is shamefully fucked, you feel your dick hardening even more
>she gives your tip a lick, her tongue having a hard time keeping onto it as Flash pistons into her
>she's getting her saliva all over your dick, before clumsily managing to wrap her lips around it
>her every pant from Flash's every thrust is now exhaled onto your dick
>you feel the air from every breath
>she sucks on it, as Flash picks up pace
>before long she takes it out, stroking your dick
>"Does that make you feel better, anon?"
>you're still looking away from her marehood getting pummeled
>you feel a magical pull, as Twilight brings your head to look at her
>"Does it?"
>she manages a stern tone despite being fucked and obviously in pleasure
>you only nod silently
>she's about to bring it back when you hear a loud grunt

>Flash rears up, his cock buried deep inside Twilight, and you know he's cumming
>soon enough you see cum leaking out Twilgiht's marehood
>feeling sick and aroused, you look away
>one hoof holding your dick, Twilight slaps Flash's playfully with the other
>"Flash! I said outside"
>her voice is anything but scolding
>he only pulls out, wiping some of his cum onto her flank, before leaning back, panting
>Twilight rolls her eyes, and looks at you
>"Sorry about that, he gets excited sometimes"
>what the actual fuck
>Twilight's still gently stroking your dick so it only gets harder
>she soon lets go, letting your erect cock bob a little, as she turns around
>and starts fucking licking Flash's dick, getting the last of the cum off of him
>she turns her head around, shaking her plot, cum filled cunt in full view
>"Well? It's only fair, anon"
>you look at her marehood, it's fucking disgusting
>you barely have time for a response as you feel her magic pull your dick in

>you feel her hot vagina close around you
>and the warm sticky cum coat your dick
>you retch, as her magic pulls your hands over to hold her ass
>the cum Flash wiped earlier now coats your fingers
>you're not even putting any effort, Twilight is just using you as a fucktoy now
>you see Flash's hoof over her mane, stroking it as she sucks his cock
>the cock that fucked the hole you're now fucking
>you soon start gripping her ass with your own muscle
>her magic relents as you start thrusting into her on your own
>ignoring the slicking of your cock fucking a fucked cunt
>and the feeling of some stallion's cum hugging your dick
>actually not ignoring it because for some reason it turns you on
>Twilight's head is bobbing up and down on Flash's cock
>she's not even responding to you, her eyes are looking lovingly into Flash's
>you start thrusting harder to show this bitch she's still yours
>you finally elicit a reaction
>the familiar sense of her magic wrapping around your waist again

>she takes that stallion's cock out of her mouth and turns back
>"At least try, anon"
>she sighs as her magic pulls you in, causing you to thrust into her faster than before
>the excessive stimulation is quickly coaxing you to orgasm
>Twilight resumes sucking Flash's dick as you feel your body about ready to give
>suddenly you feel a tight force squeezing your dick
>it's pulled out and pointed away from Twiligt, onto her sheets
>"Nu-uh, not inside, anon. You know I don't like it inside."
>she had somehow got that cock out of her mouth while you weren't watching
>she strokes you off, her magic giving you a hand/magic/whateverjob even better than your hands could
>soon enough you cum, your seed drenching her sheets
>you're panting heavily as she turns around again
>Flash's cock is erect again
>you turn away because looking at dicks is gay
>you see Twilght positioning her cunt again, and you know she's going for a second go
>you hear the familiar flapping of flesh on flesh as they resume their fucking
>it fucking hurts
>"I'm doing this for you, anon. You like it, don't you?"

>before you react, she pats the spot next to her
>where you cummed
>"Just sit and enjoy the show, anon"
>you look at Flash, humiliated, crushed
>he smiles that smug smile, before holding a hoof up
>it hangs there as he fucks your Twilight
>suddenly you feel a magic force grab your hand
>and it flies up and hi-fives him
>or whatever the pony equivalent is
>his hoof returns to caressing your waifu's ass
>"It's rude to do that, anon."
>Twilight's moaning in pleasure again
>something she wasn't doing while you were fucking her
>she tugs you again, and you find yourself sitting down on top of your cum
>it fucking digusts you, and Twilight brings your head to watch
>she's not letting you look away
>his thrusting gets louder and you know what's coming soon
>he grunts loudly again as he cums inside Twilight once more
>this time you're forced to watch it in its entirety
>you hear a shout from Twilght as she arches her back

>he soon pulls out, Twilight's cunt overflowing with two loads of his seed
>and some of Twilight's marecum
>he uses her fur as a fucking rag as he wipes his dick over it
>Twilight just lays there, panting, obviously happy
>her magic releases you, and you just look away, dejected
>Flash gets up, trotting towards Twilight's front
>he leans down and they kiss in front of you for a few moments
>he finally breaks it, and you can see a trail of their saliva connecting their lips
>"Catch ya later, Twi"
>and he starts heading out, just like that
>Twilight waves good bye to him, and he's finally gone
>Twilight finally returns her gaze to you and sighs
>"So did you get my tampons?"
>you bury your face in your hands and cry
