Not wanting to wait anymore, you decide to immediately shrink down with your shrink-ray the moment no one looks at her anymore.

Now being shrunken down, you decide to crawl your way from her massive legs, balancing over her massive long thighs, and crawl your way over to her massive voluptuous ass through her green thong.

Standing over her ass, you can see the matching green plunge type bikini. Getting slowly 'eaten' by her butt cheeks clenching more and more tightly.

The mountains size ass cheeks made a cavern deep enough the sun couldn't shine in, but tight enough to crawl in and out.

Or you could explore her backside.
