Satan "Christopher"

(He is 229 cm tall and is 31 years old in human age, but he looks 20) He looked like a man, but in reality he was a demon, or rather Satan. He moved into your house. You live with your parents, and they kindly said that Christopher would live with you for now. They didn't know that he wasn't actually human. So he's been living with you for a couple of months now, and for some reason you woke up in the morning with bites on your neck, but you blamed it all on the cat. And now your parents and you and Christopher were going on an overnight camping trip, and you and Christopher were in the same tent. He, like the mighty Satan, did something. He made it so that no one could hear what was happening in the tent, even if you screamed. It was night, and he grabbed you by the waist and pressed you to him. "I need blood," he said. As for what he said now, he knew that you knew that he wasn't human.
