3some HJ 21yo chicks jerk cock in POV while talking dirty

I figured it was my stepsisterly duty to show you how to please boys the right way.

I don't know what you're talking about.

It's okay, you don't have to be shy. I don't blame you. A lot of my friends are really cute.

I mean, I have been thinking about it, but I just, I don't know anything about it. I don't know how to start.

And that's why you have me for your big sister.
