DESCRIPTION
"Momoi and Midori undergoing huge breast expansions.
Momoi growing to huge size, her top fully popped open her breasts fully exposed. Her looking down and feeling at/ lifting her own breasts in disbelief.
Midori's breasts noticeably only about half the size of her twin's. Her top still barely intact, a generous amount of cleavage showing, barely hanging on by a button. Her tugging/ adjusting her shirt as she looks at her twin's breasts with an annoyed, envious pout."
