Madrastra enseña a su hijastra a comer una bbc por primera vez en un trío con el novio de la hija

My step-daughter don't know how to fuck, because she never have been sex, but one day she introduced me to her boyfriend, he is very tall, he is black and I thought that has a Big Black Cock. Then they came up inside to my step-daughter's room. I feel that something could happen there, so I stared to watch them. When I saw they was touching each other and kissing. I came in into the room because she was doing it in the wrong way. I started to teach them and we ate all that delicious black big cock together
