You pick up the wand from the bed and grip it tightly, excited for your next wish. You look at Jessica and mentally command the wand to make her butt grow steadily until you wished it to stop. You lean back and unzip your pants, letting your boner fling up to stand proudly in the air. You sit there like that, getting ready for the moment to run over and fuck her. In the meantime, you watch the magic happen.
Jessica had returned to inspecting her ass in the mirror, and smiled as she saw her butt grow again. Her buttcheeks grew larger, reaching the size of basketballs. Her hips grew wider to accomodate her girth, giving her a well-defined hourglass shape. She ran her hands down her figure, but kept watching the mirror. Her butt now looked like two bean bags, jiggling a little as she moved. Her rear continued to grow, larger and larger until they reached the floor.
Jessica sat down on her new butt, smiling at her reflection in the mirror. She yelped in suprise, however, as a new growth spurt started. Her hips spread out more, thighs thickened, and her legs grew longer so she could walk properly. After a few minutes of growing, you wished for her to stop. Walking over to her, you noticed that your head reached her crotch. This new height was surprising, for you were six feet tall.
You stand in front of jessica, watching as she felt herself. You Walked all around her, feeling her butt, checking out how big she was now. After a couple of minutes, you eventually figure out her ass is about ten feet wide and sticks out about six feet. Mentally thanking your dad for moving into a house with big bedrooms, you look up at Jessica's face. Since her pillars of legs were about six feet now, she stood at a grand height of roughly nine feet.
Jessica seems to notice that the vibrator is still in her clit, and pulls it out. She flicks it off and throws it on her bed. She walks over to her closet, making a thumping sound whenever she takes a step, and opens it. Your jaw drops at what she pulls out.
