My submissive-an evil angel

I hated my twin sister's best friend.

Her name was Lucy.

When we were younger, she tormented me endlessly.
She was blonde, she was 36-28-34 , she was HOT and still...she WAS a bitch!
Now, she is something, something very very different. Lucy, my twin sister's bestie was an evil demon to me, the very girl who had spoilt my entire childhood, adolescence and I thought maybe even my whole life. I hear a knock and after a few minutes find her sitting by my bedroom door completely naked and with lust and submission in her beautiful eyes.
"Master? Can I suck you?" Her angelic voice said. I smirked at her.

How had she become like this???
