Unintended and agonizing anal penetration - my penis accidentally slipped and penetrated her tight rear end

In a fervent frenzy of passion, I found myself lost in the throes of pleasure with my girlfriend. Our bodies intertwined in a dance of desire, when suddenly, my arousal took a turn for the unintended. In a moment of carelessness, my erect cock slipped and found its way into her tight rear end. The pain on her face was a sight to behold, but the sight of her luscious ass being stretched by my size was too enticing to resist. I couldn't help but push deeper, her moans transforming into cries of discomfort as I took her in full. The raw, brutal act unfolded, a mix of pain and pleasure, as I claimed her tight backdoor. The sight of her big ass being stretched to its limits left me breathless, culminating in a hot, creamy finish inside her. This is the true essence of amateur anal sex, where accidents can lead to the most pleasurable experiences.
