Newlywed Twin Swordswoman and the Curse of Sexual Lust - Version 1.0 by karaage-tomato (Eng) - Adult Sex Game

A rather standard H-RPG in which our female protagonist, Dorena, is a newlywed adventurer all set to get started on the next phase of her life as she and her husband move into the town of Walp. Unfortunately for Dorena, her rose-tinted life is soon to be darkened when she is cursed by a monster while exploring a dungeon. A curse that greatly amplifies her lust when night falls. It's a race against the clock as Dorena struggles to undo her curse as she dives deeper into the dungeon, seeking the monster that had marked her.
Whether her relationship with her husband survives this ordeal will be up to the player...

Now, with that summary out of the way. Let's get down to brass tacks. I know you all can see the tags on the game and the words on the cover art.
I know this website and the people who frequent it and I understand very well what you're all dying to know:
"Is vanilla avoidable?!"

Unfortunately, I can't say that it is. There are some vanilla scenes, disgustingly heartwarming ones no-less, but if you can manage to get through that, there should be plenty of NTR content for you all to enjoy!
