In Liones, the weather was pleasant, a slight warm breeze in the air. The perfect weather for doing laundry. All across the kingdom, families were doing their washing. Contrary to popular belief, laundry days were fun and often looked forward to. It was a chance for gossiping with neighbours and children playing in the sheets and tubs. In Liones, the royal family was no exception.

The three princesses stood in the castle grounds, each wearing their old clothes. On days without lessons, they'd often help out around the castle. Today, they'd decided to take on the task of doing their own laundry. Something Elizabeth was particularly grateful for.

She'd recently been called into her mother's room where she'd been told that she'd have to start wearing proper undergarments now that she was getting older. Namely, a bra.

Elizabeth's chest seemed to grow overnight. One day she was as flat as a pancake, the next she was jiggling like a plate of jelly. Something that wasn't going unnoticed by many of the castle's younger guards.

The budding princess had been red faced when stuttering to seamstress, but the woman had been kind. She'd offered Elizabeth multiple cloths to pick from and even gave her tips about what would be most comfortable. Elizabeth left that day with several new bras, as well as some new matching panties.

Needless to say, she didn't want other people handling her underwear right now. It was still all too new for the young girl and she was embarrassed even looking at them, let alone imagining someone else handling them.

Grabbing the scrubbing brush, she began to create suds all over her clothes which were now in a large silver tub. It was hard work, but she didn't mind doing it.

"What's going on here?" a voice piped up. Elizabeth squeaked and pushed her underwear to the bottom of the tub. She especially didn't want a certain blonde Holy Knight to see the lacey lingerie.

"Hello Sir Meliodas," Maragaret said cheerfully," We're just doing some laundry."

"Do you guys have any spare tubs?" Meliodas asked suddenly," Because the Sins and I have been meaning to do some laundry as well."

"Of course," Margaret smiled, standing up, gesturing," Their over there. Please feel free to join us."

"Will do!"

Soon all the Sins had joined in. Diane was using the nearby pond to clean her clothes as they were simply too big for the tiny silver tubs. Ban simply messed about, resulting in King having to also do his laundry. It was funny to watch when Ban poured a sudsy bucket over the fairy's head, causing a small fight to ensue. Merlin simply snapped her fingers and Escanor appeared, eager to assist his fair lady in anyway. Gowther seemed to be quite content cleaning his own clothes, muttering away about "society" and "ideals".

Meliodas sat near Elizabeth, who was focused on making sure her lingerie didn't float to the top. She was so focused, that she didn't notice Meliodas creep up behind her.

Suddenly, Elizabeth felt a mass of sudsy bubbles on top of her head and she heard the roar of Meliodas's laugh. Looking at her reflection in the water, she couldn't help but giggle at the mass of bubbles on her head.

"Two can play at that game," she thought to herself as she grabbed a handful of water, tossing it playfully at the Sin.

Meliodas stopped dead in his tracks as he was splashed. He slowly turned to Elizabeth, whose smile disappeared slowly.

"Elizabeth…" he said before a huge grin appeared on his face," It's on!"

Soon a day of laundry turned into a fun all out war with bubbles and water being tossed on every individual. By the end, everyone was completely soaked and breathing hard. No one noticed the approaching footsteps.

"What's going on here?" a voice said. Everyone turned to see Queen Caroline standing with a smile on her face, bemused at the scene before her.

"We were doing laundry but it got a bit out of hand," Elizabeth admitted.

"Well, you're all completely soaked," Queen Caroline said firmly," I'll have the maids dry everything. For now, I command that all of you go inside and have a bath at once."

The three princesses sighed, causing the Sins to chuckle as they reached for their own wet laundry.

"Didn't you hear what I said?" Queen Caroline exclaimed," I said all of you. That includes you Sins. I don't want anyone catching a cold."

"Yes, your Majesty," the Sins bowed, slight smiles on their faces. Diane had a small frown on her face, which the queen noticed immediately.

"Diane, the royal family owns some of the nearby hot lakes. I insist you use them whenever you wish."

Soon, the maids came out, each grabbing a tub of soaked laundry. They were tasked with drying and ironing the clothes.

…

Later that night, Elizabeth heard a small knock at her door. Opening it up, a maid stood there with a small laundry bag in tow.

"These are your clothes, Princess Elizabeth," the maid bowed before quickly leaving. Elizabeth smiled as the memories of the day came back. She opened the bag, expecting to see her undergarments and such neatly folded.

She was wrong.

Inside was a pair of black pants, a red shirt and… black boxers!

Elizabeth shrieked as she dropped the male undergarments, her face as red as a tomato!

She'd gotten Meliodas's laundry.

Which left the horrid question…

Where was her laundry?!

…

Meliodas sighed as he received his bag of laundry from the maid. It had been a fun day with Elizabeth, one he'd treasure for years to come. Opening up the bag, he was confused to see a white blouse, a pink skirt and…

A matching set of white, lacy panties and a bra?

Meliodas heard Elizabeth's shriek and chuckled as he realised whose lingerie he was holding. His face was slightly pink though as he held the garments. Pushing them back into the bag, he placed it on the table and went to bed.

He would need plenty of sleep before the awkward exchange in the morning.
