Step sister caught masturbating in the shower, kept it secret from parents, but received assistance to orgasm

My step sister was in the shower when she got caught jerking off. I didn\'t tell my parents, but I helped her finish. Later, she showed me how to use a sex doll and we had some fun. She\'s a tight pussy and loves to be fucked hard. She\'s a whore and a slut, but she knows how to make you cum hard.
