When i was 15-17 i was always feeling horny and felt that i needed to jerk off every day. One night i was feeling weirdly attracted to my sister and ended up jerking it to her. I ended up jerking to her almost every day for a few months to the point where i would sneak into her room and steal her bras and panties where i would then cum in those or if they were dirty i would sniff them and lick them.
