Getting Too Big

You barely had the dorm door locked before she was already bouncing on her toes, purple hair swaying, that black bow perfect against the white collar.

“Okay, okay, sit down,” she said, voice bright with pure science-nerd glee. “I finally got the concentration right. The formula from lab today? It’s stable this time. Look—”

She peeled the navy sweater vest up just enough to show the underside of her already-impressive chest, then pressed the little applicator against the soft skin between her breasts. A cool blue gel spread and vanished.

“Three… two…”

It hit fast.

Her tits swelled under the sweater like someone was inflating them from the inside. The fabric went taut, then tighter, the black bow lifting as the soft weight pushed up and out. She laughed, delighted, fists clenched at her sides.

“Oh my god, it’s working. It’s actually working. Look at them—mmph—they’re already so full…”

You watched the sweater stretch across the new heavy curves. She was grinning, proud of herself, bouncing once on her heels so they jiggled hard against the tight navy knit.

Then the second wave hit.

Her smile faltered. The sweater creaked. Her hands shot up, gripping the sides of the growing mounds as they ballooned past anything the vest was designed for. The hem rode up. Her skirt’s waistband dug into her soft belly.

“W-wait—why isn’t it stopping?” Her voice went higher. “Babe, they’re—mmmph—getting too big. They’re still going—”

You could see the panic and the heat mixing in her eyes. Her fingers sank into the dense, swelling flesh, trying to hold them back as they kept pouring forward, round and heavy, forcing her shoulders back. The sweater was painted on now, every curve outlined, the fabric straining so hard you could hear the soft creak of the threads.

“It’s not… it’s not leveling off,” she whimpered, looking down at the impossible soft mass pushing into her face. “I can barely see over them. Fuck—why won’t they stop?”

By the time the third surge finished, her arms were locked around the tops of two massive, sweater-stuffed orbs that completely hid her mouth and chin. Only her wide, glassy eyes peeked over the dark navy curves. Her voice came out muffled and shaky, hot breath warming the fabric stretched tight across her face.

“Mmmph… getting too big… they’re so heavy, babe. I can’t— I can’t even see the floor. Why isn’t it stopping…?”

She stood there trembling in the middle of your dorm room, thighs pressed together under the little black skirt, purple hair falling around the enormous soft wall of her chest, completely at the mercy of the formula she’d been so proud of ten minutes ago.

And it still hadn’t finished.
