A beautiful woman seduced me, but I have a girlfriend. What should I do?

My girlfriend once had a colleague who asked her to work in the company to seduce me! Call me if you have anything, and chat and say that we can have dinner and play together!

I want to chat with her, eat and play, but I was busy and annoyed at that time! So I always refuse her, and I scold her if she coquetry! Hang her up!

After a few times! My girlfriend is so happy that I prove in my heart that I only love her! So take off your clothes and have sex with me! Crying like a slut! After that, the bed was full of debris!

But she doesn't know about me!
