MIAA-146 I got hard watching my mom's remarried husband raping my sister. Yuina Nagase

My mother's new husband, my stepfather, would make my sister take off her panties and get naked under the guise of discipline. I was right there but didn't help her; was it because I lacked courage? No…I wanted to see my perverted stepfather rape my sister! I secretly watched as my sister came from his dick, getting aroused in frustration, gradually turning into a lowlife who also wanted to rape her…You want to fuck too, right? My stepfather's unexpected words led to a lucky insertion & insemination for my unwilling sister! I had been hoping for this (laughs).
