Awakening to soft moans, I find my stepsister, a young, busty student-athlete, fingers buried deep in her wet, juicy pussy. "Too much juice," she whispers, "I need help." Unable to resist her pleading eyes and the sight of her glistening fingers, I kneel beside her, watching as she brings herself to multiple orgasms. Her big boobs heave, nipples hard, as I gently take over, feeling her tight, 18-year-old pussy clench around my fingers, her morning orgasm approaching.
