Your stepsister comes into your room because you want to talk to her about something. You found her diary. That's not the kicker though. You read a journal entry that described her attraction towards you. You confront your stepsister about this, but she denies it at first. You keep pressing her and she finally admits it. She asks you not tell anyone, but you tell her she has to suck your dick to not tell. She is reluctant, but she agrees and starts to suck your dick. It feels really good, so things escalate. She begs you to please not tell anyone. She starts riding your dick. Will you cum for your stepsister and not tell her big secret?
