Naomi Swann - Her Crush On Step-Daddy Part One

My stepdaughter, Naomi Swann, comes in one night to ask if she can cuddle with me. I have no good reason to say no, but, the way she looks now, it is just...difficult. I don't want to hurt her feelings, and she snuggles up next to me. She must be able to feel how tense I am, and she turns over to go to rest. I clear my mind and let myself drift off, then I wake to the sound of soft moans, she's got her fingers in her panties and is getting herself closer and closer to cumming, I am frozen, my mouth is dry, my cock gets ROCK hard and I can't even think to stop her when her hands start running over me and she starts telling me how she feels. What can I do when my stepdaughter is the most beautiful girl I've ever seen?
