You wake up stepMommy because you are wanting some intimacy, first she refuses but it was easy to convince her because she was dying for it, she starts to fuck you but your stepsister is just beside in bed, she awakes and start to ask questions, like "what is stepMommy doing?" "why is stepMommy naked?" She was so angry at her interruption that she keeps telling her do not bother them , she doesn´t want anyone to disturb this special moment with her special boy.
