Innkeeper's assistant in a fantasy world of reversed sexual morality

One day, you were reincarnated by the great truck kun, in a generic fantasy world where the sexual morality is reversed.

As a human kid in a villages you didn't have any outstanding talents so you just started helping out in your parents' farm, once your sister inherits it, you'll be married off so you wrote to your innkeeper uncle in a town and asked him for help.

He agreed to hire you as a waiter/assistant who needs to clean the rooms and help the customers.

The work wasn't as hard as working on the farm. After two weeks of training, today's the day you start working.

"Timmy, take this bread and stew to table 2", my uncle shouted from the kitchen. He cooks and his wife is the innkeeper.

I took it to the adventurers sitting there, an elf mage and a human paladin, the paladin was checking me out, causing her mage friend to glare at her. Seems like he likes her. Too bad, he's probably a tsundere. "Here you go sweetie," I smiled at her and the mage, "ask me if you need anything else".

My aunt called me again to take food to another table, an all female group of a warrior, a thief, a sorceress and an alchemist. They were laughing about something and stopped when I came. I placed the food and drinks, while I was turning around to leave, someone dropped a glass, I looked at the table and the warrior was laughing sheepishly, I smiled and bent down to pick up the glass, suddenly someone slapped me on the ass, I straightened immediately and looked at the group, all of them were turned away from me and looking innocent. I didn't want to start an argument and left immediately after glaring at them.

The next order was for a pair of orcs, a younger female who looked like a berserker and an older male shaman. The shaman whispered to me when I reached their table, "it was the thief who smacked you on the ass," "I figured," I told him, "she's the only one wearing a ring on the right hand and has the smallest hands."

"You should have fought back", the female orc grunted, "and risk losing customers?" I argued back.

"Hmm", she turned back to her food.

The rest of the guests were quite normal, old men and women travelling somewhere else, families, etc;

A few hours later, it was closing time and after showing the guests who would stay overnight to their rooms, we cleaned up the kitchen and the hall.

My aunt and uncle sleep in one room and I have a room of my own, because my uncle's sons left after marrying.

The guests staying overnight were the paladin and her mage 'friend', the all female party and the berserker, her father, the shaman said that he had some work in the town and left after eating. He should be gone till the morning because we close the doors till the morning.

We usually ask the guests if they need anything in the night, before closing up and going to sleep.

I knocked each door and asked them if they needed anything, the elf asked for some milk, the foursome asked for some water, the orc asked for some more food, so I packed some cookies and milk for her.

I could try to have sex with any of them, while delivering the goods.
