My step-sister is a raw slut who can't be satisfied if she doesn't have sex once a day, and when she doesn't have a partner, she uses my dick to relieve her sexual desire! We're step-siblings, but it's obviously not right for us to do it together... and when I asked her if I wanted to cum inside her raw, she said, "Then just pull it out when you're about to cum," but as she cums over and over, she holds my neck tightly! Of course, there's no way I can get it out, so she uses a DDT lock and forces me to cum inside her! She said I could cum without her permission, but that was all a lie! She had wanted me to cum inside her from the beginning...
