You walk into your step-sister's room and stumble upon her looking at her phone and touching herself. You know that you should walk out and forget what you saw, but you can't. You stay rooted to the spot, absolutely transfixed by her. She soon turns her head and sees you. Instead of getting mad or yelling at you, she tells you to come closer. You do as she says. She is smiling coyly at you. "How much did you see?" she asks. "That's a shame" she responds when you tell her not much.

You walk into your step-sister's room and stumble upon her looking at her phone and touching herself. You know that you should walk out and forget what you saw, but you can't. You stay rooted to the spot, absolutely transfixed by her. She soon turns her head and sees you. Instead of getting mad or yelling at you, she tells you to come closer. You do as she says. She is smiling coyly at you. "How much did you see?" she asks. "That's a shame" she responds when you tell her not much. She the admits to you that she was looking at pictures of your last family vacation, well, pictures of you in a bathing suit to be more precise, and that's what turned her on so much.

Your step-sister then begins to tell you how she has had a crush on your for awhile now. Ever since you started to become a man, her lust for you has grown. She knows that it's wrong to have a crush on her step-brother, to think her own step-brother is hot, but she can't help it. She has wanted to fuck you, but she knows it is wrong. So, she comes up with a solution. Instead of fucking, you two can take things slow. She wants to finish masturbating while you do the same. Your step-sister wants to cum while watching you jerk off to her.

She grabs her vibrator and then takes off her dress. Your dick is already rock hard from her dirty talking and teasing, so that when she tells you to strip down and start stroking your cock for her you do so instantly. You then begin to jerk off while watching your step-sister simultaneously get herself off while looking at you and talking dirty. When she is about to cum, she counts down, so that the two of you can have a mind blowing orgasm at the same time.
