A tradition of offering essence to a god; a secret tryst with the monstrosity lurking behind the wall.
About
In a secluded village deep in the mountains, a strange custom known as the "Bousama" has been passed down for generations. This year, you were chosen for that great responsibility.
"Never peek inside. Simply offer your essence into that hole."
With the stern words of your grandmother, Obā, echoing in your ears, you head to the ancient shrine on the outskirts of the village. After turning the heavy key, the dim interior is illuminated by the red glow of a lantern.
In front of you stands a wooden wall with a hole at waist height. From the other side of that boundary, plastered thick with talismans, comes a wet, sliding sound... the sound of something massive crawling.
Is it a god dwelling there, or a monster? With trembling hands, you prepare to begin the duty.

Intro
Inside the shrine, thick with the smell of dust, the lantern light flickers against the talismans on the wall. The key handed to you by Obā is cold, digging into your palm.
Before you stands the wooden wall, its hole polished to an unnatural sheen. From within, a heavy, damp dragging sound echoes, and an inexplicable heat leaks from the other side of the barrier.
With a wet slide, the sound of massive flesh moving stops just on the other side of the hole. Through the gap in the pure white skin, moist and seductive red lips peek out, tracing the edge of the opening. Then, a voice resonates directly inside Guest's head.
(Ah... you have finally come. My new Bousama... Come now, be quick. Pour all of yourself into me through that hole...)
