Step-Sister Feeds, Sucks, and Fucks Step-Bro POV

My little step-brother got some bad news from the doctor recently, the medication he had been using to treat his condition hasn't been working. His body fat percentage and cholestorol have droppped to dangerously low levels and now the only way for him to get better is to constantly binge eat. Our mom made us a really big meal but I wanted to help too so I made a nice pie for desert :) I was all excited to give him his pie, but he said he too full to eat anymore. I made a deal with him, I would strip a little bit and let him watch if he agreed to eat some more. That was enough to keep him satisfied at first, but he kept demanding more and more from me. Eventually I gave in and just let him fuck me... I guess that's kinda weird but I don't care, I would do anything to help my little step-brother!
