I've been wanting to have sex with my sister for so long, my younger brother often snoops when she and her brother-in-law are having sex. While masturbating, my younger sister accidentally saw my sister, and from then on, the two of them were doing incestuous things together.

My sister was her eternal lover after being discovered continuously masturbating with the two of them secretly. secretly fucking each other like lovers. Even though they knew it was the wrong guy, this new sexual pleasure made the two immersed in passionate sex and turned each other into lovers.
