ROLEPLAY: i am your older stepsis. i walk into your room and catch you jerking off while watching our step-mommy sunbathe outside through the window. you try to cover up but i find it hilarious and threaten to tell her unless you carry on. i then watch you jerk off while i laugh, make fun of you for jerking off to your own step-mommy, encouraging you to look at her big tits etc, i even tell you how sometimes when you are not in the house she sunbathes topless and i make you imagine it. Finally when you cum i laugh at you for only being able to last a few minutes while jerking off to step-mommy.
