Heart Shaped Burn Marks (Natsu X Male Reader)

This was originally going to be a one shot, but I decided to turn it into a book, it will have slow updates because I'm not familiar with Natsu x readers because I love Gray and I feel like I'm cheating on him by reading Natsu x reader. I can already hear the hate. I love Gray, deal with it. Picture not mine. I do not own Fairy tail.
