Cow (Halloween day 8)

The plastic tub slipped from Jenna's grip, clattering across the kitchen tiles. "Shit!"

Her roommate, Chloe, didn't glance up from her phone. "Drama queen. It's yogurt."

Jenna scooped the container, fingers slick. "Not yogurt. It's... special." She held up a tiny, unlabeled vial filled with cloudy liquid. "For tonight."

Chloe finally looked. Her eyebrow arched. "That looks sketchy. What is it?"

"Something Mia gave me." Jenna twisted the cap off. "Makes you lactate. Thought it'd be hilarious to squirt milk at people. I'm a cow, right?" She gestured at her makeshift costume: black leather pants, a tight long sleeve leather top showing off cleavage, and a flimsy cow-print headband perched on her long head of hair.

Chloe snorted. "You look like a confused biker. And drinking random drugs? Bad plan."

"It's fine!" Jenna tipped the vial straight into her mouth. The liquid tasted bitter, chalky. She swallowed hard, grimacing. "Mia said one vial. Quick kick." She tossed the empty glass into the sink. It shattered. "Oops."

Chloe sighed. "Text Mia. At least confirm the dose."

But Jenna was already grabbing her keys, buzzing with anticipation. "Party starts early! I'm helping set up." She bounced out the door, leather creaking.

The walk to Kyle's frat house felt weirdly... warm. A low ache settled deep in her chest. She ignored it, focusing on the crisp October air biting her despite her outfit.

Inside, Kyle's place was dim and empty except for him and two others—Sarah dressed as a zombie princess, and Dave draped in black scrubs, stethoscope dangling.

"Doctor Dave!" Jenna grinned, already feeling a strange pressure building behind her ribs. "Wanna see my party trick?"

Dave laughed. "What, mooing?"

"Better." She grabbed two empty pint glasses from the snack table. "Stand back." She squeezed breast to the nipple in a milking motion. A sharp pang shot through her, followed by a startling hiss. Warm liquid streamed forcefully into the first glass.

"Whoa!" Sarah gasped.

Dave stared, then grinned. "Prescribe me some!"

Jenna filled the second glass, her skin tingling strangely. Dave snatched it, taking a sip. "Tastes like... warm almond milk?"

Jenna laughed, but it caught in her throat. The pressure wasn't fading. It was swelling, relentless, pushing outward against the tight leather of her top. A seam near her shoulder popped with a sharp ping.

She looked down. Her chest strained against the fabric, stretching it impossibly taut. "Um..."

Another seam ripped near her collarbone. Milk sprayed out in a sudden, thin jet, hitting Dave square in the face.

"Hey!" he yelped, wiping milk off his face.

The spray arced wildly, splattering Jenna's own face. It tasted sweet, oddly rich. Panic flared as the swelling accelerated. Her breasts ballooned, heavy and hot, pressing down like overfilled sacks. The leather top shredded completely.

She stumbled backward, gasping. The weight was immense, pulling her forward. Her knees buckled. She hit the floor hard, pinned on her hands and knees. Each breast, now easily the size of a beach ball, pulsed and throbbed beside her head. Milk leaked steadily onto the cold wood floor.

Sarah screamed. Dave watched in disbelief. Kyle froze. Jenna was stuck there on the floor slack jawed with milk dripping from her mouth. The absurd cow ears still crookedly perched on her hair.
