I soon realized the fantasy I most liked the idea of. I was sick of being a scrawny, mediocre boy no one noticed. But unlike most boys who feel like that, I didn't want to be a popular boy- I didn't want to be a boy at all. I felt jealous of the girls at school- they were so pretty, so cool, their groups were so tight-knit, and the boys (even ones like me) were so keen to get with them.
I'd come to realize that maybe I felt like that because I want to be a girl. So I figured I could use my powers to find that out. I locked my door, went to my bedroom mirror and undressed, and once I was stood naked looking at my reflection, I willed myself to turn into a beautiful girl, so pretty that everyone would want me.
An intense, warm sensation swept over me as hormones inside me inverted themselves, and slowly I changed from male to female. My penis got hard from the confusing sensations and I came, shooting cum messily over the mirror and floor. I noticed my nipples were hard too, the first big sign of my femininity emerging as my body developed guided by new hormones.
My body went from scrawny to petite, my muscles more lithe and my hands and feet more dainty. I saw my hair extend partway down my back, my neck slim and my facial features soften and giggled in my new girlish voice as I saw myself look, sound and feel less and less like a boy. My body turned practically hairless besides my head and my skin turned more supple and smooth to the touch. I formed soft curves as I developed an hourglass figure with wide hips and a slim waist.
Finally the changes took hold in my chest and crotch, seizing my manhood and turning it to womanhood. Soft flesh flowed into my chest as I breathed deeply, pert breasts sprouting on my chest as my nipples extended, rounded and widened so they could be suckled on. Further down my penis receded into me, my shaft gradually vanishing while the head reshaped into the sensitive nub of my clitoris. I felt my testicles clench, and with two wet pops they tucked into my body, reshaping into ovaries and learning to produce not sperm but eggs. Around them I felt myself developing a female reproductive system that stretched down towards my flesh, where my scrotum had sunk inwards and its seam unsealed as it became the lips of my vagina.
I looked at my transformed body in amazement. I loved how I looked, and I could tell from my pretty face, big soft boobs and large ass that a lot of people would too. Fuck, it'd be fun to make out with a hot boy and have his firm hands play with my boobs while I stroke his hard cock, and have him bend me over and fuck me up. Maybe a guy could even fuck me me against a shower wall or a window and make my boobs press against the cold glass while he pounds me? I see the thick white cum I had shot from my cock and feel my new feminine juices drip from between my legs- I want that shot inside me by a handsome man as his balls press against my flesh and he groans with pleasure at how tight I feel around him...
I blush as I realize just how much I'm losing my composure. This body makes me really horny, apparently!
