Yes. But you'll do it as a stranger

"I don't want it to ruin your relationships with the sister. Neither I want to go to jail" You say after a long pause necessary to consider all options "She shouldn't know that it is me or that you assisted in her ****"

"Well, it makes it harder" Carrie put her hand on her chin in a cute way, indicating that she is thinking about options. "She knows your voice. So you'll need to remain silent and masked. Or we can blindfold her."

You hardly believe that you and Carrie are discussing details of the future of her younger sister. "The main question is where will we do it. Maybe at her home?"

"No" Carrie shakes her head confidently "Unless you want to gag her first. Neighbors will hear her screams. Besides someone may spot how you enter her home. Her neighborhood is rather active even during the night. How about hiking? I can bring her to some remote location and she'll be all yours"

"Carrie, I said that I don't want her to know that you are involved. Should you bring her somewhere and disappear, it will be very suspicious."

"Right... I'll go me make us coffee and think it through" She walks away allowing you to ogle her ass. It immediately brings your thought to Cassidy, to her very similarly shaped bottom. Your dick jumps as you imagine pushing Carrie's younger sister into a wall and violently taking her through backdoor caring about nothing but your pleasure. Are you really going to do it? Yes, you do. You have no doubts about it anymore.

Soon Carrie comes back with two cups of hot coffee "I got an idea how to make sure that she'll not suspect anything" She says giving you the cup.

"I am listening," You ask and sip some invigorating coffee

"You need to **** us both!" Carrie said with a giggle "Imagine **** two sisters in front of one another! Isn't it any ****'s dream?"

"Are you sure that it is a good idea?" You must admit this does sound arousing and worthy of trying.

"Yes. Two go sisters will go hiking to a wild area. After a long walk they'll stop to rest and fall asleep only to later find themself naked and bound by some stranger. " Carrie grins like a movie villian "Of course, only Cassidy will trully fall asleep, I'll add some sedative in her drink. You will be able to have fun with us for a day or two" she takes a sip from a cup "And this way I'll be able to see how your fantasy will come true! So, do you like my plan?"

"Yes" You are surprised how easily you agree to this.

"Great!" I'll start talking to her about having some sisterly time together. Hope she will be free to do this soon.

Next weeks you make more detailed plans together. You pick a nice spot in a forest, bring some supplies to the area, get a good all-terrain bike to allow you to leave the forest quickly, discuss all possible poses and ways of how you can use Cassidy... Finally her trip with Cassidy is arranged on a Friday.

You go to nearby area by the bus, then find well hidden bike and start moving towards the planned location. Should everything be all right, you'll find sleeping Cassidy ready to be used by you.
