My step-sister catches me masturbating then demands for her to be roughly f*ked until I cum on her

I stepped back from the bonfire late one night to relieve myself and there saw my young step-sister sleeping. She demanded sex before I continue fooled around with my dick. I complied, plugging her taut pussy vigorously until we got our respective orgasms. So many men, including her husband, had craved this particular taboo yet it felt so right.
