OMG!!! Stepbrother caught wanking...

Whilst looking for my stepbrother Chris, I walked past his room. I couldn't believe my eyes... the guy was lying on his bed wanking his cock. He hadn't even closed the door. I have to admit that I've always found him hot. So I seized the opportunity and supported him on his "mission". After I had blown his hot cock, he fucked me thoroughly. That was pretty good to start with, but as his big stepsister I now feel it's my duty to teach him something else ;) As I take this job seriously, he's even had his first threesome - with me and a girlfriend of course (I'll show you that next week).
