I wasn't expecting my step-son home so soon. Nobody knew especially not him that I was having an affair. I can't believe he came home early and saw me getting fucked by my lover. I tried to deny what was going on but my step-son is far to smart for his own good. I can't believe he caught me. Now he looks at me as if I am a slut. Even worse, he is blackmailing me. I don't want my husband to find out about the affair so I did what any good stepmother would do and gave into my son's demands. I hope this will be the end of things and my step-son doesn't hold this against me any longer.
