Someone on the other side of the room

The two of you shifted your focus onto someone else in the room, Rebecca. You could have decided to go and stay with her before coming here, but you made the decision to go to Jemma instead.

Rebecca is 23 years old, stands at 5 foot 10, has very short bleached hair and 30F cup boobs. (You know the size because she has told you, on more than one occasion.) You remember that they actually look much smaller than an F cup, but its purely because she is so thin that they are larger, but they still look beautiful, standing on her chest under the shirt.

She is currently sitting in the corner of the room, reading a book. She is partially hunched over, her arm resting on the back of another chair, and her head resting on that arm.

She is also currently wearing a pair of comfortable jeans, and a loose white T-shirt, which has a very slight V-neck to it, not low enough for her cleavage unfortunately.

You focused and watched as her breasts slowly shrunk into her body. She didn’t notice at first, but when they shrunk from F down to DD, and then down to D again, she started to realise something was up.

Her face was showing concern and confusion, as her top and bra seemed to feel looser. She put her bookmark in and put the book down, before checking to make sure no one was watching. Obviously, at this point, you made yourself and Jemma invisible to her, and moved closer for a better view.

You watched as Rebecca slowly opened her jacket a bit further for her, and gasp. She grabbed her now D cup boobs with her hands, feeling her bra shift more than usual. She pulled her shirt forward for a quick peek, and squealed when she realised it was true, her breasts have shrunk.

She pulled her face from her shirt, and looked around again to make sure no one was staring.

“How the fuck” she asked, quietly, to herself. “oh god” she exclaimed, as her breasts jumped down to a C cup, and then, while she seemed to be groping them, a B cup.

Her small boobs were sitting proudly on her chest, or as proudly as they currently could, no longer needing the large 30F bra she still wore.

Before she had a chance to react any more, you decided to throw back what she had lost, but not in her boobs, in her flat arse.

Rebecca was still sitting down, when she felt her arse bubbling and rippling, as flesh and muscle started to appear there. Her jeans started to get tighter and tighter, causing her to moan in pain, until she managed to unbutton her jeans, and unzip them slightly to give them an inch or two more freedom. She grabbed her arse, only partially realising that the opposite was happening to what happened with her breasts.

“This is impossible” she said, “Just. Fuck” she yelped as her jeans started getting tight again. You felt a bit of pity, and so her jeans changed into a flowing skirt, causing Rebecca to scream again.

“How?” she asked no one in particular, feeling her skirt, and her new arse through the skirt.

She jumped up, causing her skirt to flow around beautifully. Her arse had at least tripled in size, making her a distinct arse girl now, with all her curves down below rather than a boob girl.

Carefully, she bent down to pick up her book, and she walked very slowly back to her room. Still weirded out by the fact no one noticed anything different about her, confused as to how her arse had grown and her tits shrunk, and why her jeans changed but her bra and top hadn’t.

You focused again, and made sure that when she woke from the inevitable nap she was going to take, she would be more accepting of the changes, and capable of living like this.
