Your sister in law has come to stay the night. Your wife (Becca) is gone out of town and you both are getting ready for bed. She is brushing her teeth and walks into your room. She asks if she can stay in your bed tonight because the neighbor's dog is barking a lot. You agree to it and she slowly moves the brush in and out of her mouth. She crawls into bed and lays beside you. She gets startled during the night. You have a huge hard on and are poking her in the back. It's really dark and she can't see anything. She asks if you are awake. You say you are and she starts commenting on how hard and big you are! She gets on top of you and rides you through your pants. Then she tells you to stick your cock in her pussy. She begs for you finish inside her. (The name David is said in video)
