When my mom married a black man I figured that was her business. When I realized our family had now grown in size I figured that was alright. I now had two black step-brothers, eighteen and seventeen and I was sixteen, small frame, nice tits,or so my boyfriend had told me, and pretty much a typical teenager. My mom and new step-daddy were going to the mall one afternoon, catch a movie and maybe do a little shopping. They asked if I wanted to go along too and I informed them I had homework I better focus on. They said ok, that Tommy and Teddy, my step-brothers , were at a neighbors house. I said that’s good and told them to go and have a good time.It was not long after they pulled out of the drivewayI decided to get a quick shower and then look at some school books. When I finished showering I had on a pair of panties and a tank top braless. This was normal to me . I was in my room, laying on my bed when I heard the boys come in downstairs. When they yelled, asking, “anybody home”? I foolishly responded “yes.” Then I went back to my history studies when there was a knock on my door. It was about then I realized I never had a lock on my door and guessI never thought I would. As they were knocking , the door which was not shut tight, opened a bit and I was getting up to block the door with a chair when there were my two step-brothers and they had three of their friends.
