Scum Erection From Watching His Sister Being Raped By His Mother's Remarried Partner Kurumi Futaba

Scumbag erection incest part 6! I was happy that my mom had found someone new and was remarrying, but then my beloved mom suddenly passed away... That's when everything went crazy. My stepfather started abusing me and my little sister, and forced us to bathe together. At first, I tried to help her. But seeing my little sister forced to give a blowjob to my stepfather, I got an erection... That's when I realized. It's better if she gets raped more... It's better if she gets dirtied more... That's right! I'll just rape my little sister too (lol).
