Just a little idea which came to me, thinking of how this Homunculus hated Roy for killing her. I follow the manga storyline by the way.
The rotund man sat at his desk. Father found him the top job at the factory. He was delicious. So were the others.
His wife took care of the recruiting. She offered poor residents [from faraway places, of course] grand wages, but when they spent their meager savings to come to Central, they were given enough only to survive and to send a little back home.
After every long day, he got a cabbie to take him home. They were mere snacks. He shoved taxis to the backyard. Later in the week, they'll be taken by poor cabbies looking for cheap, second-hand cabs. He wasn't allowed to touch them.
He tipped his bowler hat to the latest cab. He brushed the dust off his coat but he couldn't do anything about the fresh red stains. Oh well.
He opened the door of his modest two-storey house. "Honey! I'm home!"
She emerged from the kitchen in a sexy, strapless, black number. Only it was a regular sight to him. The tattoo showed prominently, in the middle of her chest.
"I didn't eat anyone at work today!"
He looked at her, hungry for praise. She patted his head.
"That's great, sweetie. Come, dinner is ready."
The person on the table [as could be clearly seen, in the middle of the forehead] was dispatched off with a neat, slightly browning hole. He wasn't very fresh, but good enough. The husband gobbled him in no time.
"Dear, I told you to wear your brown suit. The stains show clearly on grey. Oh well, it'll be brown soon enough."
The wife sighed. She handed her husband a napkin. He took it meekly and proceeded to wipe his mouth none too carefully.
"You couldn't find the Ishvalan?"
She sighed again.
"I wish I could. I think he's in hiding."
The husband looked crestfallen.
"We'll find him some other time, okay?"
"Okay!" agreed the husband.
The husband then paused and put his fat hand on his head, seemingly deep in thought. Then he broke into a wide grin.
"The lunch today was great."
It had been some low-ranking officer in Central. He also brought a boxed lunch with him. But he was the main course.
"Thank you, dear."
"You won't look for any other boyfriends, would you?"
She was used to being asked this every single day. She tweaked his chubby cheek.
"I won't. But I still have to find you lunch."
She kissed the top of his head. She changed into something more modest, covering her tattoo. Then she put on a hat.
"I'll go and find supper and lunch, okay?"
The husband nodded his agreement. It was nine by the time she returned. She wasn't alone. She had a man's collar grasped firmly in her hand. She called out to her husband.
"Darling, I've brought supper!"
He came rushing down from upstairs. His supper was almost inhaled.
"Where's lunch?" he asked, after he was done.
She patted his head again.
"That's tomorrow, remember? Go to sleep. You need to be at work early. Breakfast will be waiting in the office."
And so, hand in hand, Lust led Gluttony up the stairs.
I guess it's a little short, but it's my first fanfic. May do more if I get any more ideas~
