Dash for the egg.

Vanessa looked around and realized there was not much option so she began crawling toward the couple, her hands and knees pressing the grass and making it stain, her breasts and ass wiggling as she advanced, her breath became ragged with the effort of crawling, her cleavage getting bigger as her breast moved with each movement.

She tried to get to closets she could to suddenly sprint towards the egg.

When she thought the moment was right Vanessa shot to her feet and dashed forward, her boobs bouncing and swaying and her butt jiggling, Vanessa grabbed the egg.

The couple were in shock to see the underwear clad girl appear out of nowhere and run towards the tree and grab an egg before running away leaving them with a good sight of her jiggling ass.

Once she was out of their sight Vanessa reclined into a tree to catch her breath, she was blushing strongly, they had seen her, not just her butt but also her boobs bounce in her embarrassing set of underwear, her embarrassment was short lived as she had a mission, she had six more eggs to find.
