“Get on your knees...”

Rebecca commands you to get on your knees. “Just do it already!”

You know you have little choice here so you comply quickly. You look up to see your sister with a huge grin on her face.

“You know what Zack? I could literally wish anything next with your mind but I’m feeling generous. I’ll let you decide between one of three wishes, all of which you are going to actually enjoy, but first you’ll need to prove to me that you’re going to behave.”

Looking at your sister you aren’t quite sure what to expect here - she says the wishes will be ones you’d enjoy and you’ll actually have a choice... but can she really be trusted?

“I can tell you’re already doubting me. How about a little proof. No strings attached.”

Using your mind, Rebecca makes another wish. “I wish that I would feel unimaginable bliss for the next 1 minute.”

“Hollllyyyy shitttttt!” you cry out as the effects of your wish are immediate. You feel so damn good - it’s truly impossible to describe properly. Luckily you are already on your knees or you would have likely fallen over from the wave of pleasure you’re feeling.

Sadly, after a minute the wish concluded and you feel normal again - like a high you can never obtain again, you deeply wish you could continue to feel that way but you have no way of making it happen!

“Zack, you clearly enjoyed that. See what a nice sister I can be? Now, if you want to feel like that again I can make it possible but you’ll need to impress me first.”

You immediately decide right there and then that you’ll do anything she wants, all for the chance to feel like that again.

“First, take off my socks. I need a massage.”

You comply and take off your sisters socks while she smiles condescendingly at you. She then waves you over to the foot of her bed as she lays down, her long, sexy legs resting over the edge, her feet now close to your face as you kneel there.

“Rub.”

You massage and rub her feet for what feels like a good 15 minutes before she finally lets up. “That’s enough. Now... how about a little kiss? Go on... don’t be shy little brother.”

Humiliated but **** for her approval you kiss each of her feet multiple times.

“Hmm... let’s take this a little further. I know you’re my little brother and all but a girl’s got needs and honestly, I need you to eat my fucking pussy!”

“Whoa” you think, you can tell the power has gone to her head... she obviously doesn’t even care about the moral issues with her own younger brother eating her out!

“Don’t get me wrong... I know what you’re thinking. I simply need some stress relief and it occurred to me that you looked pretty damn good there beneath me, and that’s certainly where be I’ll keeping you from now on.”

You’re hesistant as she begins to slide off her panties, her clean-shaven pussy now full on display before you. “It’s so fucking sexy”, you think, “but how can I do this...”

Rebecca adds after clearly reading your mind, “You can and will do this... if you do, you’ll get your reward of a wish, one out of three possible wishes anyway. So... just eat my fucking pussy already!”

You’re reminded of what’s at stake and decide “fuck it!” as you dive your tongue right into her pussy, shifting your head up and down as fast as you can.

“Wow... chill the fuck out little bro, we’ve got all day!” Rebecca chides.

With that response you slow right down and lick her pussy as slowly and as sensually as you possibly can, realising that she will keep you here for longer if you don’t please her.

“Oh fuck...” she moans as you continue to eat her out. “You’re- uhhh- soo good- at this...” she says complimenting you’re talents.

You think back to how your girlfriend Jenny always loved you going down on her... and then you start to feel guilty... “This is cheating...” you think.

“Ahhh- fuck... you belong to me now little bro.” Rebecca replies after reading your mind again. “It’s not cheating if you’re my bitch. Although, don’t worry... I know how to share- Uhh FUCK!!”

After what feels like hours, Rebecca finally tells you to speed up and finishes climaxing on your face with her hands tightly pulling your hair into her super-wet pussy. The combination of saliva and pussy juices on your face is totally humilating for you, but your sister is loving it!
