Rosalyn Sphinx has the best stepmother in the world. One day after school, her stepmom informs her that she has been assisting her stepbrother with a specific difficulty, but she requires assistance. It turns out that his stepmother has been assisting him in jerking off. She enlists Rosalyn’s assistance in schooling her stepbrother and introducing him to the joys of pussy. They barge into his bedroom and yank him off. Rosalyn loses no time in putting his dick in her mouth and sucking him off as stepmom looks on. Rosalyn is having lunch with her stepmother the next day when her brother walks into the kitchen. His gaze is drawn to his sister’s ass, which is visible through the pale pink slip she is wearing. His erect cock attracts him to her ass like a magnet. She’s overjoyed to see him, and she’s overjoyed even more when he lifts her slip, exposing her ass, and pulls her underwear down around her ankles. He fucks her from behind, while their stepmom stands there watching them. They make their way to the sofa, where stepmom proposes he bust his nut all over her daughter’s face.
