I'm your half-sister. You're my stepbrother. You resented me and locked yourself in your bedroom. I'm here to make up with you. I began to flirt with you smoothly, taking off my robe carefully and exposing my sweet intimate parts so that you would pay attention to me. You were still offended for a while, but you could not resist me. You hastily rid me completely of my robe and then ordered me to fuck myself with the dildo in front of you while you jerked off. You wanted us to cum together
