Hey... step-brother. I was realllly creeped out when I found a pair of my panties in your room. But as your older, more experienced, and infinitely loving older step-sister, I want to do whatever I can to help you explore your sexuality in a healthy, safe environment. So, we cannot EVER tell our parents, but I want to help you get past this attraction that I know you feel for me. And if you think seeing me totally naked will help... I think that's just what we have to do...
