When my step-mother is already asleep and around 2AM, my dad wakes me up and tells me to meet him in the basement. I get a bit annoyed, not because he wants to fuck me but because he wakes me up in the middle of the night to do it. I've asked him why we can do it during the day when my step-mom is at work, he said he wants to be sure how much I really want to be with him.
