"Yeah, he's just gone for the weekend this time," Lucy replied to Levy as she brought a box of Oreos out to the living room for she and her friend to eat.
"Well that's not too long!" Levy told her optimistically. "Natsu'll be back before you know it."
Lucy smiled. "Yeah. It's just been so long since we've had much time together. Between drill and work, him taking a lot of night shifts and me having to put in longer days…"
Levy patted Lucy's back comfortingly as she took a cookie out.
"But we'll have next weekend at least! Natsu and I both have it off and we're just gonna stay home with each other the entire time!"
"And have sex all weekend, I bet," Levy teased and giggled at Lucy's blush.
"Levy!"
"I don't hear you denying it," she smirked. Lucy didn't respond beyond a playful whack to her friends shoulder.
She opened her mouth to change the subject when her phone started ringing loudly on the coffee table.
"Hello? Lucy speaking," She hadn't recognized the phone number.
"Lucy Dragneel?"
"Yes?" Lucy answered, giving a confused look to Levy.
"This is your husband's drill sergeant. I have to ask that you not harm anymore government property."
Lucy could hear a bit of a playful lilt in the man's voice, but she didn't understand what he was saying. "Government property? What did I do?"
"You are responsible for damaging government property." It sounded to Lucy he was really struggling not to laugh. "Your husband has a hickey on his neck and it's visible above his uniform collar."
Lucy's face instantly burned red and Levy burst out in giggles at the sight, even though she had no idea what was being talked about.
"I…" Lucy stuttered. How was she supposed to respond to this!?
"Don't do it again," the man continued.
"Wha- I-"
"Alright, that's enough!" she heard shouted from the background. There was a lot of scuffling and then she heard Natsu's voice again as he apparently took the phone from his drill sergeant. "Sorry about that, Luce, the guys are giving me crap and Sergeant Dreyer thought it'd be funny to call you. I love you, I'll talk to you later."
And before Lucy could say a thing, the phone clicked as it was hung up.
