Goblin Layer

Goblin Layer is a man with serious goblin fetish, a man on a mission: To wipe out every goblin nest!

After saving/traumatizing a Priestess in distress, you arrive in a frontier town... where all the men have all mysteriously gone missing, and all the women are becoming increasingly horny. And things escalate from there!

Will our helmet-wearing protagonist ever be able to form normal human relationships with the thirsty townswomen, or will he lose himself to thicc goblin girls?

The first screenshot is a pretty good summary of the story so far
