Abnormal stepsister came to the porn shoot

A man who had seen an ad in a sex industry magazine for an adult film performance asked, "Would you mind if I perform with my stepsister?" I couldn't believe my ears, but I was curious, so I called his office and asked if I could appear with his stepsister. I couldn't believe my ears, but I was curious, so I called him to my office and found the stepbrother and stepsister with a still innocent-looking girl. They are a crazy stepbrother and stepsister who decided to appear in an adult film because they wanted to be fat. In a way, is this what beautiful stepbrother-stepsister love is all about?
