Sinstress is impressed that you've held on for this long. You're just another man in a long list of admirers that are fighting for her attention.
I have a very special skill in getting men addicted to me. I'm a professional - as it were - and believe one, once I have you hooked, you'll never want to go anywhere else for your sexually perverted desires. Oh, don't think I know about all of them. The bisexual ones interest me the most, actually. After all, who knew that you were such a sucker for a big dick?
There's nothing wrong with liking men and women, but there's everything wrong with liking them both and never getting a piece of action. Well all of that's about to change today, because I'm going to teach you how to suck dick and take a big slab of meat in your ass. Once I'm through with your bisexual training, you'll want to go out there and fuck as many men as possible.
