In the heat of the moment, I stumbled upon my stepsister Laura in the bathroom, her hand buried between her thighs, pleasure etched on her face. She was startled, but I could see the hunger in her eyes. She took control, dropping to her knees and swallowing my throbbing cock whole. I leaned against the wall, groaning as she sucked me off, her full lips sliding up and down my shaft. When I couldn't take it anymore, I turned her around, bending her over the sink, and plunged into her tight, wet pussy. Her moans filled the room as I fucked her hard from behind, her big, round ass bouncing against me.
