Step-Mom and you are enjoying some relaxing TV time together, step-Dad's getting ready for work and step-mommy wants to play. She reaches her feet over towards you underneath the blanket playing with your cock until you get a boner. Your reluctant because step-dad's home, but step-mom encourages you that it's fine. Once step-dad gets in the shower step-mom undresses and tells you to fuck her... again you resist but step-mom insists and your arousal takes over and you do as your step-mom asks. You fuck her hard on the sofa until you both cum, luckily just in time before almost getting caught by step-dad.
