Swimming of course!

"Let's go!" Ella said racing downstairs. Amy giggled as she followed and saw Ella's naked butt bouncing softly with each step. Ella barely slowed down as she tore open the back door and ran and jumped into the pool for cover. Ella was so grateful for the large privacy fence around Amy's backyard.

"I didn't know you were so eager to streak and skinny dip," Amy said a little loudly as Ella surfaced.

Ella blushed and couldn't help but notice how different everything felt without her swimsuit. The cool water had helped calm the heat between Ella's legs, but being outside naked again was still making her want to do something she shouldn't. "I can't believe I'm naked outside again," she said under her breath.

"What?!" Amy said from next to Ella. Amy had slipped into the pool while Ella was distracted and was floating next to her. "This isn't your first time? I didn't know I was in the presence of a pro."

Ella blushed and explained what happened yesterday to Amy, carefully avoiding mentioning her arousal. "But it's all your fault!" Ella finished, "if you didn't take my suit..."

"Then you owe me so much, cause you would have missed out on so much fun," Amy said laughing, "cause I think you skipped a part." Amy looked down at the water and Ella realized her hands were again between her own legs.

Ella blushed but didn't argue. Amy let the subject drop and the two girls played in the water for a while. Ella even managed to forget her nudity for a bit and her body calmed down a lot.

Around noon, Amy climbed out of the pool. "Time for a break," Amy said looking at her hands, "I'm starting to get pruny."

Ella got out next to Amy and the wind blowing across her wet exposed skin quickly reminded her of her state of dress, or more precisely, lack-there-of.
