Yay! You're finally awake, step-bro! Don't try to struggle. I made sure to buy the best, most durable rope. There's no way you're getting out of it. And don't try speaking either, silly! I can't tell what you're trying to say with all that tape on your mouth.

I know you're probably wondering why your l*ttle step-sister has you all tied up like this. Well, I wanted to make sure this moment went exactly as planned. It's not because I don't trust you. I know that you always love listening to me and being around me. After all, I am your l*ttle step-sister!

But first, did you notice the dress that I am wearing? It's the same one you told me looked so great on me that night we went out with our friends and that... st*pid f*cking b*tch.... You couldn't keep your eyes off of me! And what about this gorgeous ring. MY gorgeous ring. It goes perfectly with the dress.

You see, this ring is actually the reason why this moment is happening right now. I tried being a good l*ttle step-sister. I tried giving you the freedom to run about with those tramps even though it drove me crazy seeing it. Even though we are meant to be together, I wanted you to have a basis of comparison. To realize that no one else would ever compare to how amazing your step-sister is. And then, that wh*re came along. And you got her a ring. A F*CKING RING. That st*pid, ugly cow!

Well, I'm not too proud to admit when I'm wrong, and I was certainly wrong to allow you to be with other women. So, I took care of that skank and got what is mine. This ring. And now, I'm about to get what else is mine. You.

It's time for us to finally consummate our relationship. To become one. Step-Brother and step-sister. But don't think I'm going to be untying you. No, you're staying just the way you are. I actually think it's sexy seeing my big step-bro all tied up like that. I'm going to straddle you and ride you while you remain tied up like that.

And I can see you're loving this just as much as I am. Look how hard you are. You can't wait to be b*lls deep in your step-sister's tight, wet p*ssy. It's time to give us what we both want.

And if you're good, maybe I'll untie you from the chair and let you lay down on the bed so I can continue riding you like that until we both c*m.

Remember, dear big step-brother, I'm the only one for you. This p*ssy is the only one you will ever get to experience from here on out. No other woman will ever come into your life again, and if anyone even so much as looks at you, well.... I'll just have to deal with that just like I dealt with that last b*tch.
