You've been waiting so long to see your stepsister like this. She's so fucking hot. She also appears to have a thing for you. Lingering touches, a little more "closeness" than typically would be expected of two people with your relationship. One day you find her in her room, playing with herself. She invites you in. She wants your cum. She teases you for a bit, playing first with her pussy over her panties, then fully taking them off to expose her perfect pussy. Stepsis grabs her dildo, and encourages you to stroke your rock hard cock. You love her giant 32H tits and she knows it, so she asks you to cum all over her giant tits. She wants them covered.
