Caught my plump stepsister indulging in self-pleasure, her fingers dancing over her shaved folds. Her guilty stare met mine, revealing a forbidden fantasy of group sex, igniting a desire to join her.
As I casually strolled into my stepsister's room, I caught her in the act of indulging in some self-pleasure. Unbeknownst to her, a group sex video featuring two women was playing in the background. Her attention was drawn to the screen, and she found herself becoming aroused by the sight. Intrigued, I decided to linger and watch as she continued to pleasure herself. Despite her chubby figure, she had a stunning ass and shaved, big tits that were irresistible. The sight of her solo play, combined with the group sex video, was a tantalizing spectacle. I found myself becoming aroused by the sight of her, and the thought of joining her in her solo play was enticing. The idea of a gangbang with her, or even a mff scenario, became a tantalizing fantasy. The sight of her fat, amateur body pleasuring herself was a sight to behold. The video ends with her still banging away, unaware of my presence.
