I just watched him fall on to the bed behind him and saw the first changes happen to him, his hair started to grow out and start to go a darker colour and he started to grow taller and this carried on an till his hair was dark brown and down to the middle of his back and he stopped growing once he hit 6ft. While this was going on his clothes rip and was just hanging on him showing most of his skinny chest and I could see his small dick for his new size now.
But then his dick started to shrink and his hips looked like they were expanding when I looked up at his chest I saw two lumps grown on his chest what is starting to assemble breasts, when I looked down to see what is happening to his dick I was quite surprised to see a vagina there and I took a step back so I could see him/now her in full and I could tell who she is becoming, she is turning in to my old self, I could see little changes in her face and hands and all over her body slowly becoming my old self.
After 2 minutes it was all over, she was now a 16-year-old girl with very long dark Brown hair and not light blond hear what only went done to her neck like mine now does and she now had good size boobs now and a lovely looking vagina what I could see throw the ripped cloths she is wearing and my new body was liking what it was seeing, even throw we have swapped body's now, and it would be weird to get turned on by our own bodies, I was still enjoying the view.
I just looked at her with a smile on my face now having what I wanted and said “well that is much better, isn't it Sis?” she just looked down terrified and said” what did you do to me you little brat!” sounding and specking like how I use to, I just smiled at her and explained what I did and why, wanting to steal his life, loving his life being in his body.
She just looked down at her body and started to look angry and said” GIVE ME BACK MY BODY YOU LITTLE SNOT NOSE!” I just looked up at her laughed a little bit and said” wow you even sound like the older sister now, calling me a brat and snot nose” she just looked more shocked and said “why!” sounding like she was going to cry I just shrugged my sholders and said “i did not know what the serum in the coke would fully do” she just looked down at herself looked touching her tits and looked more and more upset, I looked around the room knowing now this is all mine, the video games, the screwed up clothes on the floor, the sports medals hanging on the wall, but when I looked back I saw my old body now wearing the clothes what I was wearing yesterday, a short skirt and a thank top what didn't cover her belly button, she looked as shocked as I did finding herself i wearing them clothes, I thought it must have been part of the transformation and shrugged it off.
I looked down at my body wanting to explore it more thoroughly than I had before, so I looked up at my now sister and said “I think it’s time you get out of my room sis” with my smile growing bigger loving being the younger brother now and seeing how the table have turned” she just looked at me and started to say” we got to swap back” I'm sorry I made you go to school as me this morning and I promise to be a good brother for now on, please don't leave me like this!” I laughed and said” for starters I loved my day at school as you, being able to run around being reckless and not being stared at because of my body and the sex with Miss Simth was amazing, I mean you have a great life, I guess had with it being mine now, and now I will have all are parents support attention being a favourite child, with them taking me now to swimming and to baseball practise what they never did for me when I was 12 so yer, if you don’t get out of my room I am going to shout for mom?”
she just looked down at me desperate now and said” come on bro” not being able to say I'm no one but Bryon now and carried on saying “we can figure something out?” I just looked at her and sighed and said “well I warned you” and shouted “MOM, BECKEY WON’T GET OUT OF MY ROOM!!”
And in less than one second mum appears in the doorway saying “Becky what are you doing to your brother? Why are you bothering him?” I quickly said “she just came in here to tease me and won't leave” putting an annoyed face on she just said “BUT” but mom cut her of straight away saying ”no buts young lady, how many times I have to tell you, do not tease your brother, and you should know better to extract him while he's doing his homework!” while she's grabbing her arm and pulling her out of now my room and I just smiled and said in a in a mocking way” bye SIS” waving my hand at my now defeated sister.
Once the door was shut, I smile and jumped back on to now my bed and put my hands up behind my head feeling the short hair I got now thinking of what I should do.
