Stepsister wants to be an amateur. Blowing instructions part I

My little inexperienced stepsister has finally dared to take a first step. She would like to emulate me and become an amateur. Unfortunately, she has absolutely no idea how to do it. That is why I decided to give her a hand and give start-up help. We invited a nice user whom I have known for a while. He always has enough cum in his sack. And that is exactly what we can use very well now. My stepsister is sitting on the couch and the guy is standing in front of her. I sit right next to it and give precise instructions on what to do with the tail. When I see how horny she blows the tail, I get so horny that I get one orgasm after another. All the time I jerk my cunt. And my stepsister is also very involved in the matter. This little bitch :). However, I was particularly surprised at how greedy she was for the sperm. She tried to swallow every single drop and licked the tail clean afterwards. I think she'll be a pretty successful amateur. '
