Em, the sultry sister, can't help but touch herself, her fingers dancing over her clit as she pictures her brother's cock. When he finds her, she's breathless, her body writhing. He towers over her, his cock twitching, before grabbing her legs and pulling her close. He thrusts into her, deep and hard, making her cry out. He fucks her like an animal, her body bouncing on his cock as he grunts, their pleasure intertwined in a dance of taboo.
