The Monsters in my Bedroom

One night you awake to the feeling of your comfortable off of you as it is a cold winter night, you then sit up and your room is dark and you can't make out anything, but you feel as if you are naked which you do not recall being naked before, you look around the room and then you see it at the entrance of your room, in the hallway.

A large humanoid form is there with red glowing eyes and a very enlarge and ready cock, you have a sense that he means you no harm, and you smell his musk and as such you feel at peace but at the same time, you have a choice, rather or not to allow him to have sex with you, or do you tell it no?
