She was a very beautiful woman, 40 year old, with a daughter, called Mariah, 20 years old, and they lived on a ranch.

The problems started when we arrived, because she ordered us to work like slaves, cleaning the house, and taking care of the pigs.

When we finish the work, she always had something else to say or ask.

She and her daughter never do anything.

But one day things got worse. I was taking a shower with my brother when Mariah entered in the bathroom and said:

"- Hum, I'd like to know if you have any difference in your identical bodies... Let me see..."

So she looked to our penises, and saw something... then she said:

"-Oh, you're not circumcised... and your penises are too small, I'll talk to mom... "

I was terrified... the day before we'd spent gelding little pigs, so, the first thing that comes in my head, was about castration. When I talked to my brother, he said that she is just a bad aunt, but not crazy.

He was wrong. The next day our aunt called us and said to us to take off our clothes.

We obeyed, then she and her daughter started to examine our penises and scrotums. Then they caught us and tied each one to a table, with our legs completely opened, exposing our genitals.

Then, our aunt said:

"-So, my daugther was right, your penises are tiny, only 5 cm, and I don't know why you're not circumcised... I'll make a difference between your penises."

She fetched a sharpened knife, and looked to my brother, so she started to circumcise him.

"-I was thanking because it was not me... and it was not a castration."

But I was wrong... when she finished, she cleaned my brother's penis, got the bleeding stopped, and now circumcised, said to her daughter to suck his cock.

Then, when he had an orgasm, and came, she looked to me, and said:

"-now, I'll cut something from your body, and it's not a foreskin."

When she took my scrotum and opened it with only a cut, my testicles were free, when she cut first the right one, then the left. So she said:

"-Hum, I'll cut your ball sac now, you don't need this empty thing... "

So she cut all my empty scrotum away, leaving only my smaller penis.

Then, her daughter took us to the bathroom and washed our modified bodies and put us to bed.

Since this fact, every day my aunt makes us walk completely nude in the house, exposing our conditions: my circumcised brother, and my penis without scrotum and testicles.

Sometimes, she asks me to suck her pussy, and my brother to fuck her daughter.

My brother's penis got bigger then mine; he is at 16cm, and mine only the 5cm that I have when my aunt gelded me. It never grew more.

Now we're 18, and my brother can have girls... and when the girls ask about me, his twin, he just answers, "We have a small difference!"
