Homewrecking your marriage with my step-sister is the biggest fantasy I got since the moment you got married. I was always jealous on her, as I'm way hotter, and I deserve more than her.
I know you wanted me in the first place, but you couln't reach to me.
I just want to hear how weak am I making you and how hot I am comparing to her. Look at you, all tied up in my bedroom, while she is at work. I'm going to take advantage of your weakness and make you mine.
I will drain your balls and make you forget about your wife forever.
