I accidentally slept with my untouched 18-year-old stepdaughter, penetrating her vagina with my penis

I stumbled upon my stepdaughter in her room, her tight pussy already accommodating my throbbing dick. Her innocent gaze met my lustful eyes, but I didn\'t care. She\'s a big woman with a thick body, big natural tits, and a perfect ass. Our encounter was dirty and intense, leaving us both breathless.
