Sharing Is Caring

My biological father is a self centered ass hole who mistreated and left my mom for another woman. For a while me and my sister took care of her while she got her mental health ready. She had us very young and all three of us could pass for sisters. Right before COVID she found herself a good man who she started dating. He was a complete fit hunk, with a muscular dad bod and super sweet. He was always patient with my mom and that made us like him even more. When I hit puberty I was a complete mess with boys but he never once mistreated me. During COVID he started living with all three of us and would take my mom to work. I caught my older sister multiple times cuddling with him and I started having a crush on him and getting jealous. one morning I couldn’t help it but I was wet and super horny and gave him head on the couch. He backed off after he came in my mouth and didn’t talk to me until my mother came home. We had a talk with everyone that night and my mother actually was not mad at us or him. She mentioned it was okay since we were older now and didn’t mind as long as we wanted it. She put me on birth control and ever since he’s been fucking me and my sister at home. He is an animal and his cock is so big. I couldn’t take him at first but after a few times got used to him after riding him. My older sister recently went to college but comes back on the weekends. I can tell because I’ll here loud movements and deep moaning. When my mom gets home from work he never leaves her side and we respect that.
