I hate how I find it sexy in a way. I must be going down the degenerate hole faster than I thought. At first I thought I was taking the stairs, but this manga made me realize nope, we're going down Shinkansen-style with no brakes.
so this is basically the vore fetish combined with that infamous horror manga in where everyone has their own uniquely shaped "hole" on the side of a mountain in which they're inextricably drawn to.
