As Sean was thinking about what to do since Susan was not helping she seen one of the other girls take off her top as she started to sun bath near the pool so she made up her mind to get that top back.
Sean walked over to the ladder then taking her hands off her breast she climbed out as fast as she could to the cheers of most of the party goers.
Once out of the pool she put her hands back over her breasts as she started to walk over to where she had seen her top, she got a number of whistles and a few wacks on her butt.
When Sean got there though her top had been moved and everyone was watching her as a boy pointed up "are you looking for that."
Sean (Mary) looked up to see her bikini bra hanging in a tree "OH come on I got out of the pool like you said now give me my top."
Susan came over and said "I believe it is my top you are just using it" as she looked up "if you can;t keep track of what you're supposed to be wearing I guess you don't need to wear it."
The other guests cheered and laughed as Susan then slapped Mary on the butt as she went away.
Sean stood there for a while as she tried to decide what to do.
