Jon picked up the six sided dice and gave it a careful toss, watching in bounce for a moment on the desk before coming to a stop on two black dots.
It didn't take long before he felt a strange tingle run up his body, his feet shrinking, his legs lengthened slightly and his hips widened. His penis felt like it deflated and then slide up inside of himself, making him now a her. She could feel her waist pull in a little and her chest push out slightly. Her arms lost their muscle tone and her hands lengthened and looked daintier. She couldn't see the changes in her face but felt her lips puff a little, her cheek bones rise and her eyes grew a little larger and blurry.
It took a moment but he could feel a crawling on her skin as her clothes shifted around her body, and her vision cleared as small thin-rimmed glasses appeared on her slightly up-turned nose. She looked in the mirror and say a very thing, lithe girl. She wasn't bad looking, just sort of cute, with no real curves to speak of.
Jon, now Jamie, looked down and picked up the ten sided dice with her long delicate fingers. She tossed it lightly as it rolled to a stop on two. The change was just as quick this time as she felt her small a cups surge out, the two top buttons of her blouse popping off as she looked down at her milky white cleavage, now encased in a simple white bra. They looked to be about a DD cup in the mirror but looked simply huge from her close up perspective. She reached up and rubbed along the soft silk of her shirt against her newly sensitive skin, giving them a squeeze and bounced them a few times in her hands. "This isn't so bad" she smiled, taking a seat at the desk now, picking up the ten sided dice once again.
It rolled and bounced again over the desk top, this time settling on a 5. She gasped as she could feel her hips and ass swelling out her easy fit khaki pants into a snug fit, as she noticed her vision actually rising almost two inches as she sat from the added padding to her behind. She reached back and rubbed the soft pliant flesh contained in the taut fabric.
Jamie was almost giddy now, reaching down and picking the dice once again, sending it flying. Jamie gasped this time, as the dice settled on two once again, and her shirt surged out once more. She couldn't help but lean forward from the weight as they more than doubled from their previous size. Now resting on the desk, they were massive. Easily the size of her head if not bigger. She couldn't tell because they spread out on the desk, looking bigger from her point of view.
Jamie reached up and patted the masses, causing them to jiggle in the confines of her new sturdy, special made bra. "No wonder this body is shy and quiet, with this bust she probably doesn't leave the desk" she giggled to herself, her hands trailing down the front of the huge globes, finding where her nipples were pressed against the bra, and still making bottle-cap sized indents in sturdy fabric of the bra. He could feel his cheeks warm in a blush, likely one of many for the day.
