Your stepfamily is a bit twisted, and they take it out on your stepsister. They have her take care of stepDaddy and her own stepbrother. Your stepmom catches you hard in your bed, and they guide her into your room to reluctantly take care of you. Of course, you love it, and you boss her around. She's a brat with you, but deep down she really likes it. She sucks you, and then lets you fuck her. However, stepsmom told her that her stepbrother isn't allowed to pull out and that you have to get her pregnant! She is pissed, but she does it anyways to not get in trouble. She takes you and your cum, and you use her just like she's meant for... The next night, she slips into bed, and you don't know why, but she says she wanted to. Maybe, she likes being a free use stepsis after all...
