I caught my stepsister masturbating in the shower

My stepsister was horny, so she decided to masturbate with a dildo in the bathroom. While she was fucking her pussy with a dildo in the bathroom, I walked in and caught her. She didn't want me to tell anyone what I saw, so she grabbed my cock and gave me a blowjob. Later that day, I caught her masturbating in the bedroom and fucked her pussy doggystyle.
