Trading Down

I had this picture saved on the google doc a long time ago, when I went back to look for some other drafts I found it and I quickly came up with this.

I was only a few years older than my sister, but it felt like we were from an entirely different generation. My parents had always been hard on me, never letting me watch TV and making me do chores from a very young age, while she never had to do anything like that. They also put me to work early, when I was just a boy, making me work as a waiter at the family restaurant. I tried my best to get used to the job, but I was awkward and easily flustered. Usually I was fine, but sometimes, I would get ogled at by the old ladies that sometimes came in, and it would make me wish that I could be anywhere else but there.

I was fine with my mostly normal life, but then we found a coin, one that could swap any trait between two people. She wanted to be older, to not be treated like a kid anymore, so she wanted to swap her age with mine. I thought it was silly, and my morals wouldn’t allow me to take some of her best years from her life, but it got me thinking. I was still a teenager myself, but near the end of school, and I knew that many people would take the chance to get back a few years of their life if they could. I thought that maybe I could work out and get in shape, or maybe I could get better grades, and then I could go to college instead of having to be stuck working here. The coin would alter reality, making it so that I was always the younger brother, and I hoped it would mean that I would have it easier the second time around. But if I was wrong, I was worried that I might still have to do this all over again. The change was going to be irreversible, so I put it off, not wanting to decide on things too quickly.

But late one evening, I caved. It was so busy at the restaurant, and everything was just piling up so fast, I just wanted some time to myself. I finally got a quick break and went out at the front—and there, I saw my sister, standing there, doing absolutely nothing, without a care in the world. With a slight sense of smugness, I told her I was ready, and she got the coin out, and within seconds we used the magic.

————————————
I was much shorter—but something wasn’t right. Immediately I noticed something very heavy on my chest. A long ponytail of hair pulled down on the back of my head, leaving an electric sensation down my back. And something was… lacking, between my legs, which also felt different, in a frightening way—and when I saw her (now a he), I realized—while our bodies had swapped ages, we had also swapped bodies—leaving me as the older sister!

We stood there, looking at each other, too afraid to look away, to look down at ourselves. All I could focus on was the huge weight of my boobs, pulling me down, their true size contained only by the apron of a waitress uniform. I thought such a bust size was impossible for her, but some of the other women in the family were also well endowed—I really was in the body of my sister, aged up.

The pause was broken when I heard them shouting for her name… then I realized, they were calling for me. It… this was my name now. Not thinking, I awkwardly ran back to work, and as I went, my feminine features seemed to come with me, as if they were clinging to me, following me there. In the background, I could hear her nervous, boyish voice, almost apologetic, trying to say that it was an accident, trying to reassure me, until the door finally closed behind me—and all I wanted to think about was the next customer I had to serve.
