Step-Mommy sneaks under your blanket - step-mommy's feeling lonely because your step-dad is on a long business trip. She enters your room and asks if she can share the bed with you for the night. You agree, so she takes of her clothing... as she gets naked, you get a massive hard on. She notices it and it flatters her, she has needs that are being neglected with your step-dad being gone now. She wants to take care of your hard on and starts with giving you a hand job, making sure you're rock hard. She sneaks under your blanket to ride you until you both cum.
