Chapter 4: The Guinea Pig…cow
Cupcake gets a text, this time from Dexter, “science lab, 4pm, don’t worry I got you an outfit for the occasion, don’t worry about your false tits.”
Groaning Cupcake grabs his wig and keys and heads out the door to meet up with Dexter. “Ughh what kind of experiment could this dweeb possible need me for?”
Cupcake thinks as he arrives at the science lab. Dexter greets him with a huge grin on his face.
"Hello Cupcake!" he says excitedly. "I have something special planned for today's experiment. Something that will really showcase your talents."
Cupcake scoffs, rolling his eyes. "Okay, whatever you say, Dexter." He replies sarcastically, already doubting the success of this experiment.
Dexter ignores Cupcake's attitude and leads him to another part of the lab. "This is where the magic happens!" he announces grandly. In front of them is a large table with several bottles and vials on it. He tells Cupcake his outfit for the experiment is in the closet
, and instructs him to change into it.
Cupcake rolls his eyes again, but obliges. When he emerges from the closet, he's wearing a tiny, tight cow print sling shot bikini that shows off most of his body, complete with attached tail. He looks ridiculous, but Cupcake doesn't care - he just wants this stupid experiment to be over.
Dexter inspects Cupcake's outfit with a critical eye, muttering to himself. "Perfect," he says finally. Laughing as he takes the cow horned headband and places it over Cupcake’s blonde wig.
“Ta-da! Perfect model for the slime experiment.” Dexter exclaims, giddy with excitement. Certainly, this isn’t what Cupcake imagined when he agreed to help Dexter with his experiments, but he decides to go along with it. After all, he doesn’t want to be on the nerd’s bad side. Squinting curiously at the opaque pink/purple gooey substance in the vial, Cupcake raises an eyebrow, “what exactly are we doing here, Dexter?
And why did you pick this outfit?” He questions as he adjusts his tiny horns.
Dexter can't stop giggling to himself, “We’re testing out a new formula. Well, actually, it’s more of a growth serum.” He explains with a wicked smile spreading across his face.
Lifting one eyebrow skeptically, Cupcake questions, “Let me guess, boob growth? No wonder you said no falsies?” Cupcake nervously plucks at his tiny outfit making sure he’s “covered” as he barely fits into the tiny bottoms and has an aching wedgie.
Looking over to see Dexter preparing 2 different vials as he speaks “Don’t worry little Cupcake,” he says nonchalantly, “this first one is just a placebo. But the second one,” he says with a glint in his eye, “that’s the one we’re interested in. It’s going to make your tits grow big enough for your little brain to fit in!” giggling at his cleverness, as Cupcake’s jaw drops with disbelief.
Feeling a sense of dread wash over him, Cupcake hesitates before nodding his acceptance. “Ready bimboi?” Dexter pulls the small fabric to the side and applies the serum directly onto Cupcake’s bare chest. For a moment, nothing seems to happen. Then, all of sudden, Cupcake feels a strange, tingling sensation spreading across his skin. His nipples start to harden and grow larger, pushing against the confines of his tiny bikini top.
Cupcake gasps in alarm as he feels a strange, pulling sensation in his chest. Suddenly, his tiny breasts burst forth from the fabric of his outfit, growing bigger and rounder with each passing second. His blonde hair falls away from his face, revealing two massive melons perched atop his chest. They're so big that they threaten to overflow from the scraps of fabric still clinging to his body.
Cupcake can't believe what's happening to him.
His tits are growing larger by the second, stretching his tiny fabric until it nearly tears apart. He tries to cover himself with his hands, but they're too small to do much good. Dexter watches with gleeful fascination as Cupcake's breasts continue to grow, becoming bigger and rounder until they're almost DD cups.
Dexter's experiment is a success. He can't contain his excitement as he tells Cupcake how perfect he is for his next experiment. Cupcake’s new tits heavy with his frantic breathing drip the opaque, clinging pinkish slime, as Dexter drops the serum bottle on a nearby stool, unbeknownst to both of them the serum drips out the clumsy nerd was too busy staring at the bimboi’s new tits to worry about sealing it correctly.
Gaping, Cupcake grabs his swollen chest in horror. “What the hell did you do to me?” he demands, feeling betrayed again. Dexter simply laughs and starts clapping his hands together, as if he had just pulled off some great prank. “Oh don’t worry sissy, they’ll go back to normal after awhile, bitching and being a brat about it won’t speed up the process so relax and enjoy them, I know I am!”
Dexter smirks as he types on a clipboard he holds observing Cupcake’s reaction. The nerd’s experiment worked marvelously, he was hard as a rock trying to take notes on his clipboard. Cupcake’s tits were the size of cantaloupes now, swaying from side to side with every move he made.
Groaning, Cupcake runs his fingers over his small hard nipples. He can feel his anger turning into curiousity and arousal, his nipples are highly sensitive and the slimy goo is warm as it clings to his tits, he shudders as he moves to take a seat on the stool while Dexter takes his notes.
“Ewww! What the hell is that?!” Cupcake squeals, his tits jiggling everywhere as he jumps up from the stool, he ass covered in the slime as he feels the familiar tingle engulfing his ass cheeks.
Dexter looks up from his notes as Cupcake’s ass begins to grow, expanding outward until it’s nearly twice its original size. He gasps in amazement, unable to tear his eyes away from the spectacle unfolding before him. Cupcake twists and turns, trying to get comfortable as he feels his butt expanding rounder and rounder, making the monokini look like a g string.
"Dexter, what the fuck?" Cupcake complains, feeling embarrassed and exposed. He can hear Dexter laughing softly to himself in response, enjoying watching Cupcake struggle with his newfound curves.
Dexter’s pants straining against his throbbing cock can’t take much more as he spins the sissy around, pushing Cupcake to his knees. His hard cock flopping out as Cupcake knows the drill by now, but before the bimboi can secure Dex’s cock it flips right between his new melon tits. Without even thinking the bimboi takes Dexter’s cock and gets to work, wanting to finish the nerd off sooner rather than later, he plunges his mouth as far down as he can.
Good thing Cupcake can form a tight seal, it caused all the excess grow goo to come off on his lips, shoving it down the nerds shaft, The bimboi and the nerd both experiencing the tingling sensation as Cupcake groaned. “My wipsss!” Cupcake pulling the cock from his mouth, his lips already looking like he’d been stung by a bee as his tongue must be swollen as well for the lisp. Meanwhile Dexter is experiencing it across his entire cock as the bimboi spread the slime with his lips and tongue…Dexter’s cock begins to grow while it’s being swallowed by a pair of puffing pouty cock sucking lips.
Cupcake’s newly acquired assets are all now overly sensitive, the humiliation of the situation, the sissy feels his cocklet straining at the latex crotch of his cowkini, Dexter, although enjoying his now much larger sensitive cock, doesn’t want this to end with a blowjob as he pushes cupcake away from his lap, causing the bubble butt bimboi to pout. Dexter stands up straightening his lab coat, his cock pointing at the fridges across the room and snaps, as the nerd plans his next move.
“In there you’ll find some whipped cream pies Cupcake bring them all here, and hurry, it’s technically the last part of the experiment!”
Dexter commanded as he strolled towards the door, the bimboi knew better than to disobey the nerds orders, as Cupcake retrieved the pies from the refrigerator. He felt ashamed yet curious about the pies contents as he entered the lab again, placing the pies on the table in front of Dexter, Dexter grind knowing he’d put the grow neutralizer in the pies earlier, but it will be a surprised to Cupcake having to endure being an inflated fuck doll pie target.
Dexter absolutely planned on covering this bimboi cow slut with pies and fucking him silly, taking advantage of the fact that the bimboi was distracted by his giant tits and trying to see his own thicc ass, Dexter lifts a pie in each hand,
his plan working perfectly, as he flings the pie at Cupcake’s chest, hitting the center of his massive tits, causing them to erupt in a shower of whipped cream. The bimboi gasps in shock, feeling a sudden rush of coldness as the cream covers his chest. He looks down at his body in horror, unable to comprehend what has just happened.
“Wuttthh thaa hell wusss thaaa for Dephterrr?” Cupcake questioned with an almost incoherent heavy lips from the swollen lips. “Oh sorry, ha, I put the neutralizing agent in the whipped cream so you stop growin…now I’m just pieing you because it’s hot and well, I’m going to fuck that inflated ass of your while playing with those enormous tits!” Dexter let’s the bimboi know as he’s picking up 2 more pies.
Cupcake’s eyes squeeze shut as Dexter slams one into his sissy face, engulfing his entire mouth, eyes and forehead, dripping heavy whipped cream from his chin as the pie tin slides through his hair. While simultaneously Dexter slapped one on Cupcake’s enormous ass as it jiggled and quaked from the impact, whipped cream runs between the bimboi’s ass cheeks causing the sissy to moan…now covered lip to ass in cream, his heaving heavy tits, Dexter can’t wait any longer and guides the pie blinded blonde fuckdoll to the table in the middle of the lab and places him on it…stroking his expanded shaft with excess cream he bends the sissy over in front of him.
“Ready you over inflated sex doll?” Dexter asks the sissy prodding Cucpake’s ass with his shaft, using the inflated cheeks like a hot dog bun.
The bimboi moans and respond incoherently, his overly sensitive body wanting nothing more than to get off. Dexter takes his hips and slides his nerd cock into the buxom cow slut.
Cupcake lets out a loud moan, feeling the nerd's thick cock stretching and filling him up. His inflated tits jiggle and bounce with every thrust, sending waves of pleasure coursing through his body. Dexter can't believe how amazing this feels - it's like fucking a living, breathing sex doll.
He pounds into Cupcake's inflated ass, loving the way the cheeks slap against his skin. The sound of flesh slapping against flesh fills the room, echoing off the walls and reverberating through the lab.
As Dexter fucks Cupcake harder and faster, the bimboi feels like he's on the verge of orgasm. His whole body is buzzing with pleasure, and he can feel his cock straining against the latex material feeling as if he’ll burst through it. He wants to cum so badly, but he knows that he can't.
Not until Dexter says he can. The nerd's strict rules have left Cupcake feeling frustrated and confused, but he also knows that he needs this. If he can please Dexter, maybe he'll finally get the attention he craves.
As Dexter continues to fuck him, Cupcake receives another two pies on either side of his head, sandwiching his hair and face, the whipped cream oozing and blobbing down his features.
Feeling the nerd’s cock slide in and out of his inflated ass again, bringing him closer to the edge. Every time Cupcake feels he’s reaching climax, Dexter pulls out, leaving the sissy empty and horny. This pushes the bimboi boundaries further, as he grows more submissive under Dexter’s control.
Finally, after what felt like hours but was only 15 minutes in reality, Dexter pulled out of Cupcake's ass and came on his chest, covering those gigantic tits with his seed.
It was a sight to behold, the sticky white goo contrasting sharply with the bright pink slime and the creamy white whipped cream.
Dexter stood back, admiring his handiwork. He had transformed Cupcake into a veritable walking sex doll, complete with inflated tits and ass, and covered in whipped cream and cum. Cupcake clearing the whipped cream from his eyes with one hand and the other rubbing his latex encased cocklet as Dexter watches on, sliding a pie over on the floor between the cow slut's knees.
"God damn it Dexter, please may i cum!" Cupcake begs, trying to hold back the tidal wave of desire coursing through his veins. Tugging his sissy cock over the last whipped cream pie, as he rubs the whipped cream with his free hand over his ballooned breasts. Thinking it's odd Dexter wants him to cum into the last pie Cupcake plays with his now exposed throbbing cock. Dexter laughs, "cum into your pie silly cow bimbo, shoot your sissy load all over that pie like it's your slutty ass!"
And with that, Cupcake can no longer hold back, moaning in delight from the humiliating day. His entire body tenses as he feels himself coming, his cock pulsing and shooting cum onto the pie. It splatters against the crust, creating a messy, sticky, cum pie.
As Cupcake catches his breath, his heart racing, he can feel the heat emanating from his sissy cock, still pulsing with pleasure. Dexter walks over to the table, his hard cock now drained from cumming on Cupcake's tits earlier. Dexter takes the pie and smirks, "looks like you can make a nice dessert with that," as he swings the pie exploding into Cupcake's shocked face.
Cupcake's eyes widen in horror as he feels the warm gooey mess covering his face and neck. He groans in disgust, his mouth full of whipped cream and cum. Dexter chuckles, watching as Cupcake tries to spit the mess out of his mouth.
“Sorry, bimbo,” he says, his voice dripping with mock sympathy. “I didn’t think you’d cum so fast.” Dexter laughed, Cupcake cursed internally. He couldn’t believe how much this nerd turned him on, even when he was being such a little prick.
