By the time you got to the second floor bedrooms to put the clothes away, a strange feeling came over you. Suddenly, you were struck by the idea of your past behavior as a child. To be wearing more clothes that weren't your own. And, seeing as you lived in a house full of girls, that meant that you were limited to what they were wearing. Though, that didn't seem to bother you. In fact, that was almost the idea.
As you worked on your chores, you began to handpick a few pieces that catch your eye. All of them involved your mother's clothes, her bra, panties, jeans, and socks. She was the only one who could reasonably fit you, after all. There was Janet, but she would probably kill you if she caught you wearing something of hers. And you wanted to enjoy this without being interrupted.
When the chores were done, you gathered everything in your room and striped down.
The first thing you noticed that wearing your mom's clothes required significantly more weight than you had. Her jeans hung loosely at your waist and you had to hold them up with one hand. When you were a kid, you would stuff the clothes with pillows and blankets to buff up to your mother's size. But, at your age, that would just look silly. In fact, given how mismatched everything was on you, you looked a bit silly all around.
But you continued with it anyway. Something about the idea was calling you, even ignoring the growing tingle in the back of you neck.
You were feeling a bit heavier as you continued dressing yourself, unaware that your waistline was starting to increase from the laundered clothes. The magic was beginning to do its work and suddenly, you didn't have to hold up your pants any longer. Your butt was beginning to fill out the jeans as you focused on wearing the bra.
You had some experience with a bra given how exposed you were to them in a family of girls. It only took your a few tries to get it binded around your chest with huge empty cups, your mother was quite large in that department after all. You then threw the pink hoodie belonging to Alice over your head. As you finished with your upper body, your lower body was beginning to go pear-shaped, literally.
"Woah," you said, stumbling to the mirror and ignoring how your butt seemed to jiggle a lot more with every step. "I feel really weird..."
It was a slow transformation, but it was happening faster the more clothes you put on. Alice was a short and chubby girl with some good curves to her, but she wasn't quite as short as your mom or as wide. And mixing the clothing together was about to have a particular effect on you, leaving you not quite your mom and not quite Alice either.
Instead, you would end up...
