Happy birthday to you

In a dream-like state, you put one hand on her thighs and the other down her back. Your heart is racing, you want her so bad.

"Hey!" she suddenly exclaims, jumping out of your clutch. "What do you think you're doing? I told you it meant nothing, I'm still your sister you creep!"

"Actually," your mother interject, "he will be a little more than that from today onward."

Ashley frowns at her. "What do you mean? Don't tell me you want me to strip for him every morning!"

She chuckles and replies "Well, if that's what would please him..." She then turns to you, ignoring her elder daughter for now. "Since it's your heighteen's birthday, I really wanted to give you something special. To be honest, it's something I was planning since you were born. You're my only son, and my children are the joy of my life so I want them to be happy..." She slides behind a dumbfounded Ashley and grab her shoulders. "This is your gift from me, sweetie. I grant you property over your sister. From now on she's at your every order and you can do whatever you want with her."

"What?! The fuck?!" the beautiful naked sex **** yells. "That's not what you asked from me! You have no right!"

"Ashley dear, I know it comes as a surprise and you will need time to process, but I'm sure you will soon realise that's how it was meant to be. You are made for each other and I know you will be happy together." your mother assure her with a confident and emotional smile.

"No fucking way! I'm not a sl..."

"Hush." you suddenly order, and she close her mouth. She gives you an incredulous look, the realisation of your ownership over her slowly sinking into her mind. You point at your feet and order "On your knees." Without haste, she obeys. She walks back to you and kneel on the floor, head down to avoir meeting your gaze. You caress her long brown hair, then her chin and **** her to look at you. "Who am I to you."

"You're my younger brother..." she replies hesitantly. She swallows her spit and adds "... and my master."

"Happy birthday!" your mother cheers, tears of joy in her eyes.
