Hidden sister's naughty plan with my seductive sex toy

I've been harboring a secret from my roommates, who also happen to be my sisters. I've been indulging in some naughty fun with a lifelike sex doll that I've been keeping hidden. It's a tantalizing brunette with a body that screams fitness and a pair of big, bouncing tits. My plan was to keep it a secret, but things took an unexpected turn when one of my sisters stumbled upon me. She caught me in the act, her eyes widening in surprise as she saw me pleasuring the doll. I could tell she was intrigued, and before I knew it, she was joining in. The sight of her bent over, getting pounded by the doll, was a sight to behold. I couldn't resist, and neither did my other sister, who soon joined in. Before long, we were all lost in a world of pleasure, our inhibitions cast aside. The doll's tight pussy sucked on our cocks, and we returned the favor, our hands and mouths working in tandem to drive each other wild. The climax was explosive, leaving us all spent and satisfied.
