A sudden power outage leaves our protagonist in the dark, his eyes adjusting to the dim light. He hears a familiar voice, realizes his friend is home, and follows the sound to her bedroom. There, he finds her sprawled on the bed, her big tits heaving with each breath, her ass clad in only a tiny thong. She's lost in the throes of pleasure, her fingers working her wet pussy, completely unaware of the intruder watching her every move.
