Mary returns from her run with her shrunken step-son still trapped in her shoe. She sits down on her bed and starts to kick off her shoes, releasing David from his helpless smelly cavern. After such a long run, the little man had begun to stick to her sock, leaving him attached to them as she lays on her bed. Eventually he is able to peel himself off, but with the way his step-mom is kicking her legs around he is launched towards her backside. Landing right on her butt, David braces himself as the giantess turns over and smothers his tiny body with her huge ass. A few moments later, Mary sits down on her bed and plops her socked feet right up next to the tiny man. She has him worship them, but after feeling nothing she decides to take off her socks. Once she removes them, the room is filled with a pungent scent that almost makes her pass out. This smell though is what the bug-sized man always dreamed of. He finds himself turned on as he is dominated by his step-mom's bare soles. After a few moments his step-sister Ashley comes into the room and as the giantess tries to hide him, she accidentally makes him cum under her toe as she pressed her sweaty flesh against his aroused body. Discovering that her mom knows about David, Ashley suggests that they both have some fun with him. She flings him onto the floor and they both plant their legs over the side of the bed. Taking turns they both trample him under their feet, eventually grabbing him and sandwiching him between both of their toes. In the end, Mary asks if they can make the tiny man slightly bigger so she can make use of him. His step-sister agrees and grows him to a few inches tall, leaving him behind to whatever her mom was thinking of doing with him.
