I just came to wish you goodnight and I discover you masturbating. I never knew you had such a big, thick cock. What were you stroking to, my dear? Do you like what I'm wearing, darling? You love me so much don't you? I do as well darling and that's why I'll gladly help you. Shhh, let me help you with my hands. Step-Mommy knows her techniques, honey. I know this feels strange but we'll be quiet. I can tell by your raging boner that you love every second of step-mommy helping you cum!
