Stepdaughter Had Nightmare

Your stepdaughter runs to your bedroom and in the middle of the night scared. She had a terrible nightmare and she does not want to go back to room. Your wife is away for business so you hesitate but let her stay on one condition, she has to behave. As she gets comfortable in bed, she just wants to feel your body to keep her safe. Who knows who started it but soon both of you are naked and masturbating to each other. That's still not all that bad right? Well what about when she takes your cock in her mouth and almost chokes on it?
