Expansion focused on a character's breasts - this tag is for scenarios where the breasts are shown actively expanding, or implied to have increased in size within a short amount of time, oftentimes with expansion occurring faster than what is physically possible.

If the expansion is not explicitly shown occurring - in a sequence, comic, or animation - it may be conveyed by the character visually or verbally expressing surprise over unexpected growth or remarking on the growing size of them, along with clearly large breasts; this is usually paired with visual clues such as clearly damaged, ill fitting, or ineffective clothing

Not to be confused with breast growth, where a character previously without breasts is shown growing breasts.

Breast Expansion Causes:

• inflation - from a buildup of milk, or from the influx of some outside substance (gas or liquid)
• transformation - possibly involving magic, science, fantastical foods, or other influencing forces
• weight gain - from gaining fat, this may involve a character only gaining fat in their breasts, or more realistically the character becoming fatter overall
• age progression - a grey area, breast expansion should ideally only be tagged if the character's breasts greatly expand in size over the years, and aren't simply growing as a result of puberty

Consequences of Breast Expansion:

• Size Increase
• big breasts
• huge breasts
• hyper breasts
• Lactating
• autolactation
• excessive lactation
• lactating through clothing
• projectile lactation
• Clothing/Exposure
• bursting breasts
• button pop
• ineffective clothing
• public exposure
• straining buttons
• tight clothing
• torn clothing
• wardrobe malfunction
• bouncing breasts
• sloshing breasts
