A bikini

Jenn was wearing a bright blue bikini - one with slip-on pieces unlike the string bikinis all the young'uns were wearing, and one (also unlike the girls) which covered most of the breast rather than just the nipple triangle and made some effort to conceal the asscrack while leaving most of the firm glutes open to the air and sun. Either way, everyone was staring at Samantha's hot mom and her tanned form accenting her musculature with tanlines peeping out from their blue confines.

Jenn paid the crowd no mind, still pissed at Avery for what she had done to her daughter. Charging up the deck by where Avery was looking up and gulping, Jenn dove right in the pool mere feet from the girl.
