Barging into the bathroom, I stumbled upon my stepsister, fingers buried deep in her glistening pussy. Caught in the act, she froze, then let out a naughty grin, inviting me to watch. Her wetness coated her inner thighs as she spread her legs wider, offering me a better view. Her moans filled the room as she brought herself closer to orgasm, my presence only fueling her arousal.
