Michelle's ass cheeks clench as she feels her brother's cock pressing against her entrance. With a mix of fear and excitement, she lowers herself, her tight pussy stretching to accommodate his thickness. She rides him slowly, her hips rolling, as she tries to maintain control. Her brother's hands grip her ass, guiding her movements, as he thrusts upwards, burying himself deeper. Their fucking becomes frantic, the sound of their bodies slapping together filling the room. Michelle's orgasm rips through her, her pussy convulsing around her brother's cock. They freeze, listening for any sign that they've been caught, before collapsing into each other, their hearts pounding with the thrill of their illicit encounter.
