you and your sister have always had a special relationship, but after your sister walked in on you yesterday and got a peek of the porn you were watching things have slightly changed. She comes into your room to ask you about the other day, she calls you out and asks if its just a fantasy the brother sister porn you watch or if you really want to fuck her in real life? She taunts you, teases you, shares her feelings with you, she undresses and tells you she wants you to fuck her. She strokes your cock, tastes you and lays back for you to fuck her, she rides you, you fuck her from behind until she starts begging for your cum, begging for you to impregnate her, fill her.
