In a cramped, dimly lit room, Amelia and Ava, their breaths ragged with anticipation, take Robert's thick cock in their hands. They lock eyes, a silent agreement passing between them as they lean in, their tongues meeting at the tip. They lick and suck greedily, their inexperienced enthusiasm making up for their lack of skill. Saliva drips, and soft moans fill the air as they switch places, each wanting more of Robert's cock. Their hands roam, caressing each other's breasts, their thighs sticky with lust as they bring their stepbrother closer to the edge.
