Looking at my step daughter while I stroke

Last year my wife and adult stepdaughter were all staying in a hotel room. My step was sleeping in a rollaway bed next to the king bed in the room.
My wife insisted on sleeping next to the wall so I slept on the bed closest to my steps rollaway bed. I woke in the middle of the night to piss and when I came back to bed I could see my step in the ambient light. I stood there over her bed looking at her beautiful face stroking my big cock wishing she would wake up and take it into her lovely mouth.
I cannot remember how long I stood there stroking and looking at her. She moved in her sleep several of times, the first time freaked me out. I decided I will just continue to stroke even if she woke up.
I finally worked up a big load and shot it all over her covers. I was tempted to shoot on her face but chickened out.
