TG Caption This: Turned Into An Olympic Swimmer!

I smiled contently as I stepped out of the changing rooms, adjusting my Sunglasses onto my still damp dark brown hair, my T-shirt and shorts keeping my strong 6"4' frame cool. I'd just finished a great swimming session and was on my way home. I usually go swimming at least four times a week, But I was kicking it up to eleven as I was going to swimming in the Olympics in a couple of months. After a fifteen minute walk I arrive back home to see my little sister on her laptop on our sofa. A quick peek over her shoulder whilst saying hello showed me that she was watching some anime with a pink haired heroine. Nothing unusual there then. After washing my trunks and putting them to dry and my sister reminding me it was my turn to cook dinner, I proceeded to the kitchen. It was a quiet night overall, as our parents were away on a second honeymoon, nothing much different, my sister was being quite talkative though, mostly about her anime, she seemed to be enjoying it... whatever it is.

After a quick wash, I went to get my swimming trunks off the drying rack and noticed a girls one piece beside it. I shrugged as I guessed my sister probably had messed hers up or something and was just drying it off. The weird thing was, some force was actually pulling my hand towards it rather than my trunks. Once my hand touched it I lost all control of my body, save my mouth and eyes. I could only watch helplessly as my body pulled the girls swimming attire over my form. I could feel the heat on my cheeks as I regained control of my body. I immediately went to take the thing off, but I couldn't, it was like it was stuck to my body. After ten minutes of trying I gave up, it was then I noticed that it wasn't just my cheeks that had heated up, my whole body was warm. It took a second for me to realise that my body was slimming down, I was getting thinner, but I was also getting a little softer, and then it stopped. My body no longer had the tall muscle form of which I was used too, instead it was more delicate, slim and graceful. I could feel the muscles still there under the thin layer of fat, they were just not as big as they were before. I ran to a mirror to see what was happening to me. I gasped when I saw myself. Apparently it was not just my body that looks more girlish, my face does too. A thinner jaw, smaller nose and wider eyes all made me look like a very pretty girl. I quickly felt the heat re-surface as my hips got wider and my butt got bigger, making the suit very tight at the bottom. That was soon fixed by the disappearance of a certain defining piece of anatomy in that area. For every loss there was a gain it seemed though as, much to my dismay, my chest area started to hurt and bubbled up into two small breasts. At least they aren't too big. I caught myself thinking as I poked them to make sure they were real. After all that I took another look in the mirror to see the girl I had become, I would classify myself as my idea of the perfect looking girl but that's just me, The suit fit perfectly now.

"Wow, it worked." I heard my sister say after I spent a few minutes looking at myself in the mirror. I spun round and she was right in my face, causing me to step back. I finally had a rough idea of how much height I lost. From how I still towered over my sister It wasn't much, probably only three inches at most. Suddenly, what she said clicked.
"You did this?!" I yelled. I was surprised at just how my voice had changed, it somehow came out sounding more irritated than angry.
"Yeah." My sister replied as if it was the most obvious thing in the world.
"Why and how?" I asked.
"Well, On one of my trips to town I came across this old shop." She grinned. "Eternal Magic I think the name was, anyway, I found section in the back with a lot of different outfits in, including swimming costumes. The clerks told me they would transform the person into the perfect form for the outfit, for cosplay reasons I guess, so I bought some." She leaned forward and started lightly poking my chest. "You turned out flatter that I hoped though." She sighed.
"Why did you use a racing one piece then?" I muttered under my breath whilst swatting her hand away.
"Anyway." My sister's Cheshire cat grin retuned full force. "If you want to change back you have to complete a challenge."
