I accidentally caught my always strict sister in the middle of masturbating. She was so engrossed in fingering herself that she didn't notice me nearby. When our eyes met, she seemed embarrassed and, as hush money, made me take out my dick, sucking it vigorously or squeezing it between her tits. I couldn't hold back and shot a massive load of cum right at her. The forbidden relationship between me and my six strict sisters, all six episodes.
