Goblin Layer Ver.0.58.6 by Parodos - Adult Sex Game

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? These are the questions we must ask ourselves, as the protagonist embarks on a philosophical journey of self-overcoming, encountering various characters that mirror his own eternal recurrence, as he confronts his goblin obsession, the absurdity of his life and asserts his will to power .
