Diminished

Having an identical twin sister had always been cool. We did pretty much everything together and as the two prettiest girls at school we basically got treated like Princesses.

Boys would simp for us and all the other girls wanted to be in our gang. My sister Ashley and I got everything we could want and life was good. I couldn't have been happier being top of the social ladder - even if I had to share the top spot with my sister.

She didn't seem to mind either... or at least I didn't think she did...

One day I was in our bedroom when Ashley came in with a sweet smile on her face. Sitting next to me she stroked my blonde hair... so soft and similar to her own. "Hey babe, I'm bored... can I give you a makeover?"

There was a strange gleam in her eye, but I agreed and Ashley excitedly led me to a chair in front of her mirror and made me sit down.

Ashley called the mirror 'her magic mirror'. She would spend hours staring into it. I didn't tend to be so vain - but Ashley loved to play with makeup and costumes and things. She was always making me dress up for her.

"This time I'm going to make you look like a boy," she grinned. "Just for fun of course."

I felt uneasy but I didn't want to over-react so I allowed her to get to work. She explained what she was going to do to me and a strange sort of acceptance came over me.

She started by making me clean off all my makeup. As I wiped my face clear - the slight imperfections of my face were revealed and her prettier identical face next to mine only highlighted the difference.

Next she made me take off my clothing and underwear. She took my bra and panties and tossed them to one side carelessly. Then more carefully she began to tape down my breasts and made me put on a pair of boys boxer-shorts.

"Here..." she giggled tossing me a sock, "stuff this down your pants."

I blushed and did so, now it looked like I had a fake bulge... my own personal cock. Ashley handed me a pair of jeans, a black t-shirt and a baseball cap. I put on the lumpy male clothing, it felt rough and scratchy against my soft feminine skin.

Gathering my hair up she jammed the cap onto my head and gave me a pair of thick black glasses to wear. The lenses hurt my eyes and made my eyeballs itch. I had to squint to see properly.

"Wow, you look just like a boy now," she smiled as she forced me to look into the mirror. 

I had to admit she was right. I did look like a boy. I really looked like one.

As I gazed into the mirror my vision seemed to correct itself. Looking in the mirror made the clothes on my body seem to fit better. I was now looking at the reflection of a small and weedy boy, slightly acned face... short blonde hair and heavy black glasses. He looked a bit like a loser... the kind of boys me and Ashley usually ate for breakfast. I had to admit she'd done on a good job on this costume.

"What do you see when you look at me... boy?" whispered my sister in a sexy voice I'd never heard her use before. "I'm such a hot girl aren't I? Don't you wish you could look this good? Does it make you hard and horny to look at me?"

I wanted to laugh but the intensity in my sisters voice stopped me. She spun the chair round and sat on my lap... giggling as she ran her hands over my chest. To my surprise my chest felt flat... my breasts now completely numb.

It was strange but I was suddenly finding my sister very overwhelmingly pretty and powerful.

"Do you like pretty girls like me? Do you wish you could simp for me poor little baby?"

She began to rub her ass against my crotch with a soft giggle. The sock in my pants seemed to throb and I had a sudden strange feeling a bit like a pleasant tingling.

"Ashley... wh... what are you doing?"

"Oooh I can feel it getting harder."

She stood up and giggled as I reached down and unzipped my pants. To my horror I saw a cock now jutting from my crotch... my pussy was gone and I had a penis!

Ashley grinned and clapped her hands together in glee. "It worked! I've turned you into a boy. You're really a boy now."

"Wha... what's happening?" I gasped in shock.

"Shhhhh... start jerking your cock for me and it will all make sense."

My hand slid round my dick and began to pump. Ashley grinned as she held my gaze cooly.

"Does that feel nice? You're going to be jerking off a lot more from now on. Pumping your cock for all the hot girls you constantly simp over will feel great. With every spurt of cum you'll forget you were ever a girl. Soon you'll be just another useless masturbating boy."

She leaned close. "Finally I'll be the hottest girl at school. Finally I won't have a rival who looks like me. Just a nerdy little brother who likes to jerk off to me and my hot friends and pervs over my sexy underwear."

I groaned at the thought of Ashley now being the only sister - able to be unique and have everyone love only her. With me out of the way she would no longer have to share. She could be selfish and take everything she wanted.

"Noooo Ashley please I'm your sister."

"No you're not," she purred, "you're my pathetic simp of a younger brother. You goon constantly for hot girls and have no social status at school. You're a loser. Now say it."

"I'm... I'm a loser I groaned as I erupted and sticky white cum splashed over my tummy.

"Eugghh, gross. Clean yourself up and go to your room loser. Maybe you can jerk off some more when you get there."

She tossed me some tissues and I wiped up the cum. Looking round the room I saw it had changed. There was now only a single double bed and everything here belonged to Ashley. It was like she never had a twin.

I stood up and made my way to what had once been the spare room. It was now a teenage boys room... my room.

Taking off my cap I looked at my short blonde hair and spotty face. Booting up the computer I found in there, I saw the hard-drive was full of porn and sitting down I began to edge.

My sister was right. I was a loser. I would never understand how good it must feel to be the prettiest most popular girl in school like her.

As I began to cum again I forgot all about what I had once been and I accepted my fate.

I was finally diminished.
