Just add fluff
Yelping at the thunder, Alfred unceremoniously dumped Arthur off his chest and flew under the covers. It was a knee jerk reaction to shove his nose into the skin of Arthur’s abdomen and squeeze his eyes shut. Normally it wouldn’t have been so bad but the shapes in Arthur’s room made everything different. This wasn’t his land and it didn’t reach up to comfort him like it did at home. The only thing comforting about the land was that is was Arthur’s.
“M’ not scared,” he insisted against Arthur’s warm skin. He wasn’t. Just slightly displaced and confused. “I have you.”
Arthur laughed, patting down Alfred’s hair, “You’re cute.”
Lighting flashed again as Arthur snuggled down under the covers with the American, taking care to gently kiss his forehead, then the tip of his nose, and finally his lips. He rested an arm around Alfred, and pulled himself closer. “So…are we hiding here or something?”
“I’m not hiding…” Alfred paused trying to come up with a feasible excuse, “Well I’m not hiding okay. If you’re insinuating that I’m scared or somthin’ you’re dead wrong.” Huffing and wiggling around, Alfred secured himself to a more comfortable position lying against his boyfriend’s side and trying to block out the storm. It didn’t do much for the noise, but it blocked out the lights.
The lights were the worst part, the reminded him of things he really, really did not want to think about on his downtime when waking up next to his boyfriend. No matter how many times he told himself the past was the past and no longer mattered, it still nagged on the edges of his mind in these types of situations. The noises had always varied but the flash right at impact, that was something that would always send the panic pumping back into his veins just as if he was back on those battlefields.
A sigh escaped Arthur’s lips as he shifted to let Alfred lay upon his chest, knowing that if he allowed his arm to be pinned under the American’s head for any extended period of time, he would loose circulation in the appendage. His hands trailed across Alfred’s arms in a sort of comforting pattern, attempting to relax the tense muscles.
“It’s just a storm, remember. It’ll pass soon, and it can’t hurt you as long as we’re inside,” he cooed, starting to stroke that golden hair with one of his hands.
By Jove, you lot are nosy. 
I love you too, you idiot.
