Stepsister caught sneaking some smokes

When I got home from college today, I saw one of my stepsisters looking around for cigarettes in the basement living room. I was just fooling around by yelling at her when I guess I startled her. She is not supposed to smoke in the house. I act like I'm going to rat her out to pay her back for something she did to me but I have a different plan in mind. I'm going to offer her to fuck me. After I explain it to her she we go into the guest room. I have her start sucking my cock. Then I have Ashley get on the bed and she shows me how sexy she can smoke for me. We fuck in several positions and when I am so close to blowing my wad I get Ashley on her knees in front of me and I mouth fuck her until I just can't hold back any longer and I start to cum in my stepsister's hot smoky mouth.
