It's mating season for the dragon slayers. Natsu is a submissive slayer, Gray is a dominant devil slayer. What happens when gray discovers Natsu has gone into heat? And what happens after when an earthland shattering secret is revealed? With all chaos fairy tail is famous for attracting, will Natsu get the dominant he wants? Or will another claim him? I DO NOT OWN FAIRY TAIL, HIRO MASHIMA DOES. This is a fairy tail fan fiction. it also contains gratsu and implied fraxus so YAOI. DONT LIKE YAOI, DONT READ. thank you. Oh, and also contains edo nalu and Edolas Dragons! And maybe edo Nashi if I feel like it. Maybe.
