“G3T UP”
The voice rings through Vriska’s ears as she groggily opens her eyes,  sluggishly blinking for a few moments while she softly yawns. The dim light cast around her luscious body leaves her straining to focus but within seconds she’s already seen enough to tell she’s in quite the predicament.   Initially trying to wipe the sleep from her eyes, she soon finds she can’t even move her arms, hands staying stuck behind her back and clasped together. With struggling proving useless, Vriska takes a minute to judge her situation, being stripped and devoid of all clothing and with hands tied behind her back, a gulp can be heard emanating from her throat as she feels the cool air brush up against her exposed figure. Beads of sweat already begin drizzling down the sides of her tender physique at the ominous natured of waking up bound and naked….just as a shadowed figure approaches.
“H3H3H3” 
The unmistakable cackles leaves Vriska’s mouth going dry and heartbeat skyrocketing, for even considering the idea of her being naked and exposed in front of Terezi fills her with so much dread that she can’t help but bite her bottom lip when she walks into view. Near instantly, Vriska’s once frightened expression shifts to that of a surprised, confused look, for once she gets a good look at the Pyrope troll, she’s utterly stunned. 
With a wide grin spread across her glossy  lips while showing off her lustrous, pointed teeth, Terezi saunters and sways her hips with every step. Just like Vriska, she’s completely bare of clothing as well, letting those plump, pert breasts of hers bounce with every striding pace of her succulently thick legs, not even wearing her trademark ruby-red glasses either in fact. Palms planted onto her curvy midsection as her wide areola and udder-like nipples jostle and jiggle on her heft tits, perhaps what surprises Vriska the most about her appearance isn’t her huge breasts or that doorway-brushing ass, but rather what lies at her crotch, soaking the side her thigh in visibly thick fluid and filling the air with the wet, juicy sound of flesh slapping against flesh. 
“L3T M3 GU3SS, 1MPR3SS3D?”  Terezi mutters whilst snickering , even though Vriska can’t try to look away from the unbelievable sight.  Her eyes completely affixed on the massive, fleshy dick jutting out from the tealblooded troll’s crotch, hanging down with such tremendous weight that it’s a miracle Terezi doesn’t buckle from the impact of the tip slamming against her knees near constantly. Every inch of the massive meaty length is covered in what looks to be a glossy kind of self lubricant, drizzling down the length of her girth,with fat droplets raining down from her tender, puckered tip covered in protruding bumps.  

The daunting image of Terezi’s dick forever burned within her mind, Vriska immediately tries to defy the sense of power her captor must be feeling, chiming up with 
“Pfffffffft, is that all you got? I've seen 8ig-“
Yet her scathing remark is cut short as Terezi swiftly jams a ball gag straight into her open maw, strapping it around her head while Vriska hoarsely grunts in defiance.
“TH3R3 W3 GO”  the tealblood murmurs while she stands up straight in front of Vriska, finding it so amusing that she continues to avert her gaze just so she won’t get a good look at Terezi’s massive dick getting aroused by her presence.
“NO N33D TO B3 UPS3T YOUR3 NOT N34RLY 4S B1G” she chortles, taking a step back and giggling with while Vriska’s expression becomes confused and bewildered at such a vague comment.  Terezi wouldn’t be able to hold back even if she tried, leaving her uncontrollably laughing while Vriska hastily starts spreading her legs and looking down at her crotch, a muffled gasp echoing throughout the air from the ceruleanblooded troll and body nearly going into a spasm. A dollop of drool  slips down from the outside of her lips as she stares bewildered at one of the thickest, fattest cocks ever even seen bulging out from her crotch. All at once a rush of hormonal bliss hits her like a ton of bricks, leaving her arching her back as eyes flutter and body aches.
Her cock heaves upwards and pulsates. Every inch of its wrinkled, creases expanse feeling so oversensitive that Vriska’s mind goes entirely blank, so crazed with lust just from the sight of her fleshy, foreskin-overloaded cock growing almost painfully erect, to say nothing of how Terezi is taking in all of this and idly stroking her own prepuce-imbued dick simultaneously. 
Every pulsing throb and swell of that enormous chode renders Vriska’s usual calm and in-control demeanor utterly extinguished as she ushers forth moan after muted moan into the sopping wet ballgag. Such unfelt stimulation brining her to the very edge of her limits, eyes crossed and teeth sinking into the plastic stuffing her maw. It wouldn’t be so bad were it not for the fact that Terezi was actually getting off to it- enjoying the smell and sounds of Vriska’s struggle to compensate for the fact she’s now got a fat, loose-fitting, utterly fleshy dick drizzling precum all over her new set of swollen balls resting against the floor.  Such copious amounts of silky pre mix with ballsweat to form a oily slurry underneath her huge nuts, the faint aroma wafting up from the light blue puddle leaving Vriska slightly tipsy, with a faint azure blush appearing at her cheeks as she dimly realizes she’s practically getting off to her own overflowing fluids. 
This ultimately acts as the breaking point for Terezi, a sly ear-to-ear grin spreading over her face as she roughly grips onto the end of her dick and squeezes, enacting a plume of yogurt-thick , aged cum to end up splurting out and caking her palm in the pasty substance. The very feel and odor of her backed up seed enacts her to lose any sense of decency even imaginable, her free arm outstretching as she shambles towards the incapacitated Serket troll. Not even giving a snarky comment as she does so, or rather unable to in her debilitated state, Terezi grabs onto the end of Vriska’s sizeable length and simply rams her own tip onto hers, resulting in both scourge sisters crying out in pleasure at the incredible sensation of docking one another. 
Vriska blushes a deep cobalt blue while Terezi eagerly pumps and bucks her hips, absolutely in love with the warm, squishy expanse of their cocks ramming against one another. Her own cock being exceptionally thick and long leaves Vriska’s entire body shuddering as her fat, plump dick is smushed and compressed against Terezi’s monster length. With every shift of her weight and rock of her hips, rippling vibrations cascade against Vriska’s dick, prompting  both puckered cocktips to spread and effectively “kiss” one another in a sloppy , squishy embrace. Sounds of wet, vivid  squelches and smacks sound out all around them, the occasional grunt or whimper being heard as they give into their carnal desires and dock with each other’s incredible endowments.
“H3H3H3, H3R3 1T COM3S!”
A torrent of seminal fluid instantaneously begins welling up in each others cocks before then spewing out with the force of a broken water pipe. Spraying droplets of teal and cerulean seed fill the air like an orgasmic mist as both Terezi and Vriska give into the heavenly feelings assaulting their bodies. Even with her dick currently cumming loads of murky seed, Terezi continues to ram and compress her plush, puckered tip against Vriska’s, the numerous noticeable bumps around the rim kneading and rubbing against Vriska’s sensitive length like a kind of natural vibrator in fact. Streams of gluey cum spew forth and bloat out each of their squeezable shafts, both sets of balls hugging close against their crotches while Vriska ends up getting thoroughly coated in the mess all thanks to Terezi positioning each of their dicks  so that they both end up releasing seed all over the spider8itch’s body.

Even with each other spent and releasing the last remnants of their respective colossal loads, Terezi beams a smile as she steadily wobbles over to Vriska’s midsection, squatting over her cum-slathered figure while she lifts the end of her half flaccid length into the air. Breathing hard through flared nostrils, Vriska unearths a reverberating, baritone deep moan when Terezi tugs the ballgag free from her mouth, drool layered atop her parted lips while she hazily grunts in exasperation. Eyes glazed over and rolling back with a half lidded appearance,  the sound of her deep, hoarse breathes like music to Terezi’s ears while she cackles 
“M1GHT 4S W3LL 4S L3T YOU DR1NK FROM TH3 T4P!” 
Saying so right as she grips the end of her dick and dangles it in front of Vriska, smudging her limp, fat dick against her cheeks and wiping up the saliva slathered around her chin, replacing it with excess seed as Vriska gurgles in response. Having been exhausted almost to the point of passing out, with her last act of strength she struggles to rise her palm, trying to push the fat dick nudging against her cheek to the side, only to end up resting her hand on top of the doughy, bumpy tip and enacting a sudden surge of thick Pyrope-jizz straight into her mouth. Terezi drools at this, leaning her head back and squeezing at the base of her dick like a roll of toothpaste as she kneads and massages out every last glob of syrupy, viscous cum out her meaty prick. The unbelievable amount of surplus semen filling Vriska’s mouth overflows and completely covers half her face in the damp, musky gunk, throat bulging out as she’s forced to drink in the pure, concentrated jizz in loud gulps. Terezi slides her dick all over her face in an exaggerated way of marking her with the runny seed billowing out of her dick, rubbing her pudgy, doughy dicktip around Vriska’s cheeks before finally letting it rest against her nose, letting her breathe in the musky, muggy air rising up off of Terezi’s profoundly large girth. With the scent , taste, and feel of Terezi’s dick leaving her completely at her mercy, Vriska dully moans as she feels her own prick jostle and quiver, growing erect once more while Terezi grins 
“R3ADY FOR ROUND TWO?”
