Public Nudity/Swim in your backyard swimming pool
You slide open the glass doors leading to your backyard and strut outside with a sway in your hips and not a care in the world. The sun feels lovely on your bare skin but you don't stop to enjoy it, instead tossing your phone onto a deck chair and walking straight for your family's in-ground pool, gracefully diving beneath the surface in one fluid motion. The sudden cold sends a shock through you and you can feel your nipples hardening up almost instantly, but you quickly adjust to the cool water and swim to the far end of the pool.
Surfacing, you smooth back your hair and look around your backyard. It's a large yard, which meant plenty of grass for cutting, but other than a few trees and a tool shed there wasn't anything of note. All around the yard was a tall wooden privacy fence to keep nosy neighbors from peeking in. Not that you mind. In fact you hope one of your neighbors was on the second floor and looking down at you, seeing all you had to offer.
Despite the cool water you feel a heat grow inside you at the thought of what unseen audience you might have acquired. You turn and swim back, exposing your cute butt for all to see as the warm feeling continued to grow, just begging to be relieved.
It took some effort but you managed to ignore it, and as you reach the other end of the pool, something happens to give you another way to show off today.
