My stepsister's solo play turns into a group session with a demanding partner

After a grueling day at work, I found my stepsister on the couch, indulging in some solo play. Her plump figure and ample bosom were a sight to behold as she sensually stroked herself. I couldn't resist joining in, and before long, we were both lost in the throes of passion. The intensity escalated when my girlfriend arrived, her insatiable appetite for pleasure driving the scene. She skillfully took turns pleasuring us both, her expert mouth working wonders. The room filled with the intoxicating scent of lust as she eagerly devoured our most intimate areas. The action was relentless, our moans echoing through the empty house. Finally, the climax arrived, our bodies convulsing in ecstasy as we were showered with hot, sticky cum. It was a spectacle of unbridled passion, the kind that only a family affair can provide.
