Trapped in a Dungeon with Monsters

Left all alone by the monster subjugation squad, Shelviet was on the verge of being killed by the Monster Kings.
Just as the Monster Kings were about to kill her and call it a day, a mysterious status window popped up before them.
[The cave will be sealed forever until you have lewd intercourse with the human female.]
[Current Lewdness: 0%]
There was no way out of the dungeon unless they had 'lewd intercourse'?
"Hey, you. Are you good at 'that'?"
Wait, are these monsters... virgins?
