Stepsister agrees to jerk off stepbrother's dick

My stepbrother came to my room when my parents were not at home, I showed him my tits, he watched and jerked off his dick, looking at my tits, but then he asked me to jerk off his dick, I wanted to do it, I had never touched someone's dick before this moment, to be honest, I almost came, after that I went to the bathroom, went into the room and masturbated to orgasm three times. This will be our secret from our parents.
