This is the last time you can ask me for any favors. But why would you ask me to do something so crazy? What about your girlfriend? Can’t she tell you what to do? Well, if I must, I’ll try. Sit back, relax, and enjoy the commands from your lil sis as she tells you how to stroke your thick cock and cum for me. But not only do you get to cum, I get to let you watch me cum, too.
