In a quaint beach cabin, a brother and sister find themselves alone, the salty sea breeze stirring more than just their thirst. As she steps into the shower, her brother can't help but admire her curves through the frosted glass. She notices his gaze, and instead of being upset, she teases him, running her hands over her soapy body. He joins her, their bodies pressing together as they kiss hungrily. The shower steams up as they explore each other's bodies, her fingers wrapping around his hard cock, his hands cupping her full breasts. They fuck hard and fast, the water cascading down their bodies, their moans echoing off the tile walls.
