Take me in and I'll love and serve you ~Sweet and sexy life with a demi-human girl~

Demi-humans are treated as the lowest out of all races.

In a small village away from human settlements, Mia and her mother, who barely scraped by, were attacked by human traffickers to be sold as slaves.
"At least my daughter could be spared", as Mia's mother handed her a photo and allowed Mia to escape.

One day, Mia ran into the protagonist as he was managing an inn his father left behind.
From the worn-out photograph, the location of this very inn was noted in his father's handwriting.
"This girl's mother... There is no doubt that was father's former demi-human lover"

I decided to take Mia in for a while.
Her body was thin and her hair was dirty.
I did not seek any repayment from this girl who possessed nothing, but...

"... I... want to be needed more... Let me service you a lot as well tonight..."
