NTR Dungeon of Twisted Common Sense

A dungeon sealed by a hero in the past, wherein dwells a great demon.
Adventurers Shinon and Nia are tricked by the demon and venture inside.
A powerful hypnosis permeates the dungeon, and they engage in sexual activity without
distress.
Shinon gives over her body calmly, and shows her gapeface.
Believing being half-naked is normal in the dungeon,
believing semen is a precious foodstuff…
In a dungeon where these things seem like common sense,
will she be able to escape the demon’s bewitchment?
