Stepsister wants to become an amateur. Blowing instructions part I

My inexperienced little stepsister has finally dared to take her first step. She wants to emulate me and become an amateur. Unfortunately, she has absolutely no idea how to do it. That's why I decided to give her a helping hand and help her get started. We invited a nice user who I've known for a while. He always has enough wanking in his bag. And that's exactly what we need right now. My stepsister is sitting on the couch and the guy is standing in front of her. I sit right next to him and give her exact instructions on what to do with the cock. When I see how horny she is blowing the cock, I get so horny that I have one orgasm after another. I'm wanking my cunt the whole time. And my little stepsister is also really into it. That little slut :). However, I was particularly surprised at how greedily she lapped up the cum. She tried to swallow every single drop and licked the cock clean afterwards. I think she's going to be quite a successful amateur
