MIAA-229 I got hard watching my mom's remarried husband rape my sister. Hinase Hina.

Trash erection incest second round! My mother had a new favorite person and we were happy about her remarriage, but that happiness was short-lived... My beloved mother passed away... Everything went crazy from there. My stepfather started abusing us, and he forced my sister and me to bathe together. At first, I tried to help her. But seeing my sister being made to give a blowjob by my stepfather, I got an erection... That's when I realized, the more she gets raped, the better... The more she gets defiled, the better... No! I should be the one to rape my sister (laugh).
