I like making short stories, so here’s one for Rio!

Rio gazed downward, blushing uncharacteristically. There was a reason others called her “Big Sister.” Two big reasons.

Rio frowned, desperately trying not think of her unique predicament. She vainly attempted pulling her black blazer over those heaving sweater puppies. “Damn chest…ugh!” After a few attempts, Rio didn’t want to force the clothing any further as the seams groaned audibly.

”Christ…” she sighed, letting her right breast hang freely. Others envied, but for Rio, it was only disdain. The growth was innocuous at first. Hell, it was even inviting.

Rio was quite heavy-chested, so one or two more cup sizes wouldn’t hurt to enhance her appeal. However, that hint of greed would slowly fester in her bosom.

Rio knew she had a problem when she couldn’t view her feet while looking down. The only thing greeting her was soft, overwhelming cleavage.

Rio had to bend over a considerable amount to get a glimpse, squeezing her boobs with one arm. Even her iconic office attire was straining as her unruly body demanded to be exposed.

Suddenly, the sound of stretching broke Rio’s regretful rumination. She looked down with wide eyes, feeling a familiar quiver underneath the sweater.

They were growing. Bigger. Again.

Rio’s hands fumbled cusping her breasts. The sweater tightened, stretching the poor white fabric to its very limits. “S-Stop growing…” she quietly blurted out, as fear slowly took over.

Her squishy tits happily jiggled, almost mockingly. Rio could feel her underboob as the sweater inched up little by little. “P-Please stop…” she desperately pleaded to her chest, not wanting to expand any bigger.

After a few horrified seconds, Rio’s gigantic growing breasts finally slowed down. But her anxiety still lingered, wondering when they’d inflate again…
