She likes to be sexy and provocative, so she always wears tight clothes. But in this case it was a bad thing. They were so tight that she could barely breath. And moreover, she suddenly started growing. In a few seconds the clothes were already too small for her so they began to fall apart.
She was so embarrassed. All her lady parts were exposed. But for the men, it was such a lucky event. This is a really rare opportunity to see such a big and sexy woman barely wearing any clothes.
