The Pig King

The weakest monster Orc's story is of true love between different species.

[Game]
This game is set in a world where monsters make dungeons and make money by
beating adventurers lured into the dungeons, under the prohibition of killing.
Our protagonist, who is an Orc working in a certain dungeon administration company,
falls in love with a princess knight when such a thing occurs.
As the Orc, let's become stronger and promoted enough to confess your love to the
princess knight who should be somewhere in the dungeon of his company.


[System]
The orc gains EXP by having sex to be stronger. So it's efficient to defeat and have sex
with female adventurers around the dungeon to get EXP.
Alternatively, you can also take a platonic love route through the story, maintaining your virginity.
