You kneel

You think about your options. You could try and run, but if Rebecca ever caught you, you’d be fucked for life. Besides, you aren’t built to survive in the world on your own - you haven’t even finished school and you worry you might somehow still miss your family.

On the other hand, kneeling before your hot, older sister doesn’t seem so bad. You’ve already gone through worse, parading yourself around as a cheerleader for fuck sake. Truly, this sounds like the best deal you’re going to get.

You humble yourself and kneel before your sister, having accepted your fate (for now, anyway). You look up at Rebecca to see the big grin on her face behind her large boobs hanging before you. “I wouldn’t mind kissing those...” you think as you reluctantly begin to plant a gentle kiss on each of her feet.

You remember the deal, so you say “Thank you Rebecca for your generousity” as you finish kissing her feet, looking up at her once more before returning to sitting with your hands in your lap. “I feel like a fucking dog waiting for a treat.” you think to yourself, the embarrassement now kicking-in full throttle.

“That’s a good little sissy.” mocks Rebecca as she leans forward a little, placing two fingers under your chin to pull it up slightly. You’re now looking into her big, blue eyes, her luscious blonde hair cascades down. “Damn, why does Rebecca have to be so beautiful!” you wonder to yourself.

“I think it’s time for a little test; Let’s see how good of a sissy you really are. I want you to follow me into mom and dad’s room and I need you to follow my lead. You had better be convincing too... you wouldn’t want to let your new mistress down now, would you?”

You blink as she pulls her hand away and you nod, “N-no mistress, I would not.”

You realise you’re now calling your older sister mistress and reality sets in - “This is going to be one hell of a ride.” you think.

You continue by saying “I won’t let you down.” hoping to score some points so that maybe she won’t make things too horrible for you.

“I like your attitude, just remember - you really are my bitch now, and you’re mom’s too. Dad doesn’t know about our little deal though and I expect you to help me enjoy this as much as possible - otherwise I’ll have to start taking control of you again and believe me, whatever I have to MAKE you do will always be 10 times worse!”
