Diamond Tiara and Silver Spoon Summon

>Oh
>oh god
>how long has this been going on, you wonder?
>the pink pone straddling you looks back over her shoulder at your naked body, her eyes blue like ice
>her wide hips rock forward and back, streaks of purple and white swishing across your chest as her tail wags in tandem
>each backward motion pulls her greedy pussy away from the base of your shaft
>each merciless rock forward plunges your cock deep into Tiara's snatch, and causes her to bite her lip just a bit harder
>"Look at that loser, Silver! It's like he doesn't even like me stuffing my box with him anymore!"
>she lets out a mirthless giggle
>you've given up pulling at the ropes binding you to the bed
>all you can do is lay there in a puddle of mare-cum, hoping against hope that this will be the last time
>you thought that the fourth time you'd popped, even though all that had escaped you was a wimpy spurt and a howl of pain
>it hadn't gotten any better when they came back for round five, Silver Spoon's already whitewalled snatch taking you just as hungrily as it had the first time
>at least they'd given you the courtesy of a half-hour break and some water before this time
>despite yourself, you let out a weak little moan, the throbbing in your overworked cock strengthening as your balls contract yet again
>"Ooh~! I know what that means!"
>the pink pony leans further forward, stuffing as much of you inside her as she can hold
>Tiara's tongue lolls out of her mouth as her walls squeeze you for the umpteenth time
>her forehooves run down your thighs and she lets out a breath she hadn't realized she was holding
>"Nnngh~, that's number 6!"
>"Yay! Now for..."
>Silver Spoon hugs her friend and then pulls her forward off your shrinking cock, the two of them fairly dancing in excitement as they shout in unison
>"THE GRAND FINALE!"
>The grey-coated filly crawls over the edge of the bed, the covers making a squelching sound as she approaches your utterly defeated cock
>her cohort circles around to the headboard, still dripping from her latest round on the rodeo
>the snotty pink pony leans over you, smirking as she runs a hoof delicately around your nipple
>"I'd say we're sorry that we tied you up and used you all night..."
>she gives the tit a careless flick, before sitting beside you on the bed as she spreads her body out over your chest
>"...but my daddy told me not to lie to ponies."
>As she talks, you can feel a spongy warmth on your balls, as Silver Spoon's tongue runs between them
>she takes one tender nut into her mouth, suckling gently, then the other
"Please..."
>you rasp, your voice hoarse from moaning and dehydration
"I can't... don't make me... again..."
>the pain you feel in your shaft is how you imagine runners' legs feel at the end of a marathon
>but like the autism level of a board about cartoon horses
>slowly
>inexorably
>it rises
>your battered warrior is standing at attention once more, and Silver Spoon's constant tongue ministrations keep him there
>"Don't worry."
>Tiara runs her hooves across your chest as she sits back up, drawing imaginary little symbols on you as she speaks
>"It's almost over, and when you finish..."
>she whispers in your ear as her hooves trace up your neck
>"it's going to be amazing."
>Silver Spoon's tongue has finally found the head of your cock
>it circles clockwise, then counterclockwise, now flat, now thin
>her breath against the tip of your manhood is, weirdly enough, soothing some of the strain
>her lips press against it, surprisingly tender after the rough riding they've been giving you
>"tegaf sugnumuh a r'u"
>Diamond Tiara chants some nonsense words as she moves her hooves in another pattern
>Silver Spoon's kisses trace down your frenulum and shaft
>"lleh ni s'kid skus mohm ru"
>Tiara's lips are less than an inch away now as her blue eyes stare into yours, half-lidded
>Spoon's kisses reverse direction, ending with a smooch back at the tip
>"flesru l'lik duhs u burcs t'ker teg"
>pink lips meet yours as they finish breathing the last words, tongue reaching for the back of your throat
>you feel a warm moist sensation as Tiara forces her nose against your groin, her throat pulling plaintively at every inch of cock it's stuffed with
>there is no pain now
>only a moan muffled by Tiara's long, forceful frenching
>and the feeling of a filly's tongue swirling around your shaft
>dimly, you wonder how the little filly can breathe
>she probably can't, but you're in no position to push her off of you
>even if you wanted to
>your hips buck, and you feel the sting of cold air as the momentum pulls the grey filly's head back a bit
>it's quickly replaced with warmth as she reclaims her spot at the base of your shaft
>you repeat this a few times, and soon she doesn't need your hips moving to keep her head bobbing
>you feel a heat rising in your loins
>this is not your average everyday orgasm
>this is an advanced orgasm
>you struggle at your bonds once more, not to free yourself but to make sure that the pony with your dick in her throat doesn't try to pull off
>you break Tiara's extended kiss with a primal scream, your balls contracting as you blast a rope of jizz straight down Silver Spoon's throat
>and another
>and another
>and another and another and another
>Tiara looks almost shocked as she turns to watch the spectacle of her friend downing a monstrous load of your seed
>you're captivated yourself as you see her normally lithe form bulge a bit
>after what feels like an eternity, you feel one last spurt of baby batter break free
>that... that was it
>you thank whatever dark god smiled upon you that that was it
>Silver Spoon pulls herself off of you with an audible pop, still sporting a mouthful of spunk
>swishing it around her mouth like some lewd listerine, she smiles at you
>it's not a happy smile
>Tiara joins her at the foot of the bed
>they kiss, and you see a dribble of your jizz leak from the exchange
>the snowball complete, they break the kiss, looking over to you.

>"It begins,"
>Silver Spoon chortles, a dribble of purple escaping her lips
>"IT BEGINS!"
>Diamond Tiara cries, cackling with glee as a matching purple sludge drips from the sides of her mouth
>from somewhere between them, you hear a soft rhythm start
>they open their mouths, more sludge bubbling up from the two fillies' throats
>you know this rhythm, you realize
>ice runs down your back
>you are still roped to the bed
>there is no escape
>you cannot stop it
>nothing can stop it
