Your giantess step-sister always got what she wanted. So when she found out she could have some fun torturing you with her massive ass, that's exactly what she did. Pretty soon it became a more common occurrence. With you at the mercy of how she felt, you would be picked up and tossed into her cheeks at random for hours at a time. Exhausting you until you couldn't stand it anymore and were forced to release. Over and over again until you couldn't stand it. Eventually she would get tired and take a nap, but even then her huge cheeks would lock you in place making it almost impossible to escape. However you still would, but not long before she would find you and do it all over again... but, it could be worse. Right?
