This Is No Longer a Costume

Standing in the middle of the room, staring into the large mirror, Tim frowned.

Reflected back at him was a tall blonde with long wavy hair, wearing a tight brown top and a pair of workout pants. Her belly exposed, waist slim... And her breasts — massive, gigantic, and way too fake-looking, which wasn’t far from the truth, considering they were literally two fitness balls. The stomach, by the way, was also part of the clever costume — a silicone sculpted torso that wrapped over the body, hiding any trace of Tim’s real figure.

He sighed and reached for the edges of the top to strip off the whole farce. His fingers slid across the firm surface of the "skin," and Tim frowned again when he suddenly felt his fingers — as if there was no silicone layer on his belly at all. The fabric wouldn't budge, and the breast under the costume shifted slightly, as if... real.

— What the hell?.. — he muttered, grabbing one of the "balls" with both hands.

He expected a puff of air, the resistance of latex... but instead, his palms sank into warm, firm softness. And then, as if in response to his touch, a light tremble rushed through his body, and somewhere deep inside, a clumsy heat flickered, while he could clearly feel his hand on his own body... on his own tit?!

He yanked his hands back, glaring at the reflection. The girl in the mirror looked even more real now, her breasts still slowly bouncing from the sudden movement, seeming even heavier now and tugging at the skin, while her stomach pulled in subtly with each breath... not a single hint of fakery.

The creak of the door made him flinch.

— Ooooh, who’s this tasty little treat? — came the familiar voice of his roommate, Max.

Tim spun around sharply, noticing how his massive breasts pulled him slightly to the side — nothing like how they’d behaved during the party. No, this was way too real, like there were actual boobs there, not some kind of balls.

— M-M-Max, s-something’s really fucked up! — he croaked out in a hoarse voice, immediately going cold as he slapped a hand over his mouth, elbow bumping against one of the huge soft mounds sticking out from his chest — and he felt it with that elbow. But the voice! It was too high, melodic… girly! Even in his own ears it sounded like a poorly done impression of a sugary blonde.

Max smirked, lazily shutting the door behind him and leaning on the frame.

— Party’s over, princess, — Max grinned, arms crossed as he openly checked Tim out.

Tim swallowed hard, panic rising to his throat. Everything in his reflection screamed that he wasn’t just a guy in a costume anymore — he was a real… girl. He quickly looked down at his stomach, still clinging to some desperate hope. Silicone sculpted abs? Now they looked completely real: smooth curves, thin skin, a deep navel. Tim ran his hand along the bare strip between the top and the pants. No seams, no sticky edges of the costume — just warm, living skin that twitched from his touch.

— F-fuck... — he exhaled shakily.

Max's grin widened, and he took a step forward.

— Something wrong, gorgeous? — his voice was overly soft, almost mocking.

Tim backed away, feeling the heavy boobs bounce slightly with every movement, annoyingly grabbing his attention. Each bounce sent weirdly intense sensations through him, ones he couldn’t ignore. He shut his eyes tight, trying to focus, but the pressure of the tight top stretched across his chest pressed down, the straps cutting into his shoulders, pushing his breasts out even more.

— Max... — he whispered hoarsely, almost under his breath, — this... this isn’t a joke. Take it off! Help me take it off!

The only response — a soft laugh.

His hand slid forward without hesitation and tugged the thin fabric of the top upward. The material dragged unpleasantly against the skin, caught, stretched—and in the next moment, the enormous, heavy breasts spilled out, trembling heavily under their own weight and immediately beginning to sway.

Tim barely managed a gasp. He felt everything—the cool air gliding across bare skin, the gentle sway of the heavy flesh on his chest, hanging down and slightly bouncing with every breath. The warm air of the room instantly touched the exposed skin, raising goosebumps across its soft, silky surface. This was real. Something was definitely sitting on his ribs.

Max let out a low whistle, leaning in, staring like he couldn’t believe his eyes.

— Holy shit... — he muttered. — That’s... not a costume?

Trembling, Tim lowered his gaze, expecting to see boobs there—but still not really believing it, still desperately searching for any seam, any hint of a fake layer. But they were real. Warm, heavy, no frame, no hidden padding.

Meanwhile, Max, as if he'd forgotten about the rest of the world, reached out and firmly grabbed both breasts. His fingers sank into the warm flesh, squeezing and spreading the heavy mounds, making Tim gasp from the uninvited pleasure. His lower belly immediately responded with a wave of heat, and his knees buckled on their own.

— Ah... — slipped out of Tim on a breath, loud and unexpectedly sweet. His face flushed instantly, like he’d just been slapped.

Max froze, staring hard at the girl in front of him, his fingers still buried in the soft firmness of her tits. Tim tried to say something, to push him away—but instead, his body betrayed him: the slender waist arched forward on its own, pushing her chest further into his touch.

Max muttered a curse under his breath, as if he couldn’t believe it either, and his hands slid lower, over her flat stomach, and then even lower—to the waistband of her workout pants. Tim’s heart was pounding so hard he could hear it in his ears. He wanted to squeeze his eyes shut, to run, to hide... but he just stood there, trembling, too scared to move.

The fabric of the pants stretched gently and slipped slightly downward. A chill of air burned against her thighs. And then Max’s fingers carefully touched the intimate triangle between her legs—where there was no longer anything male, but instead something soft, warm, and unbearably sensitive.

Tim sucked in air through his teeth, whimpered, nearly collapsing on the spot from the overwhelming sensations. That light touch set fire to her whole body, stealing the breath from her lungs.

Max yanked his hand away like he’d been burned, his eyes wide open.

— Fuck... — he whispered. — You’re a real... girl...

Tim’s eyes flew up to him—full of fear, shame, and... something else. Something sweet, terrifying. Something snapped inside her—broke—and everything around her disappeared. Only Max remained. Tall. Strong. Familiar. Necessary.

Little hearts flickered in Tim’s eyes—bright, fluttering, gradually overtaking the last fragments of her thoughts. Her lips trembled, her body leaned forward on its own, her nipples like blades now from the heat pulsing inside her.

She rose up suddenly and pressed herself against Max, her heavy breasts squishing against his chest, making Tim moan softly as she felt herself melt inside, dissolve, aching for Max to take charge and tell her what to do. The heat between her legs pulsed, growing with every touch, every look, every thought and craving.

— Well, shit, why not... — Max growled in her ear, and Tim whimpered, hugging him tighter, pressing into him with her breasts, her skin, every inch of her new body—burning to fulfill her new role as a bimbo slut, thanks to the meddling of a self-taught witch who didn’t like Tim’s sexist costume.
