Write me a story that takes place in Granblue Fantasy, between NAME_1, and her big companion dog, NAME_2. One night NAME_1 was curious about NAME_2's capability, she lay on all fours, while NAME_2 swiftly approached her swiftly from behind, as she felt a thrill of excitement run down her spine as NAME_2's warm breathed on her back,  and soon they were more than friends.
