Ma belle-mère me rend fou

My Step-Dad is out of town on business again and my stepmom gets really lonely. I feel bad for her. She is so sexy and my step-dad pays her no attention. Since I graduated from college and moved back home she and I have had so much sexual tension. I need to show her what an younger man can do for her. I told her we would go out on a date and let her get all dressed up. After seeing her tits in that dress and they way she was flaunting herself for me. I knew she wanted it.
