My step sister explores her sexuality with a new sex toy

I was gifted a sex toy by my boyfriend as a birthday present, and I had been eagerly awaiting the opportunity to test it out. I decided to give myself a little treat while my stepsister was on a webcam, showcasing her sexual prowess. I had always been intrigued by her, and seeing her pleasure herself only fueled my desire. As I slipped the dildo into my shaved pussy, I couldn't help but imagine it was her touching me. The sight of her blonde hair framing her face and her glasses sliding down her nose only added to my arousal. I found myself lost in my fantasies, pleasuring myself with the toy and imagining it was her touch. When my stepsister noticed me through the window, I quickly hid, feeling a mix of guilt and excitement. I knew I had crossed a line, but the thrill of it only made me want her more.
