I'm Fucking Your Girlfriend

I have always loved both women and men. Recently I started seeing a beautiful girl who has a boyfriend who knows about us. However, he has never met me. I have his phone number though which she gave me. Whenever we see each other and have amazing sex, I text him and tell him how much of fantastic time I had fucking his girlfriend. I usually wait until I know he is the office at work. Knowing that he is desperate to be part of our lesbian affair and it will turn him on at work but he won't be able to do anything about it but fantasize. Soon enough I know he will crumble and join us, until then we all get great pleasure out of teasing him with our exploits
