As I strolled into the room, I spotted my stepsister lounging on the sofa, her expression a mix of curiosity and longing. A mischievous glint in her eyes piqued my interest, and I noticed a small, intriguing device on the coffee table. It was a ball vibrator, a gift from my recent trip to China. I had intended to use it with my girlfriend, but something told me this was not the time. With a devilish grin, I handed the device to my stepsister. Her eyes widened in surprise and anticipation as she took it in her hand. I instructed her to insert it into her tight, wet pussy. She obeyed, her eyes never leaving mine. The vibrations caused her body to writhe in pleasure, her moans filling the room. I watched as she rode the waves of ecstasy, her face contorting in bliss. The sight was too much for me to resist, and I quickly undid my pants, thrusting into her. The room echoed with our moans, the vibrator working its magic on her.
