Look even closer...

You're looking even closer, bending over to try and find a good angle. What the heck is this carving supposed to be? It kinda looks like a butt, but there's some other stuff around it.

While you're examining the altar's astonishing stonework, a demon passes by the altar and sees you leaning over the altar, legs spread to lower yourself in front of it. The demon is delighted that someone has finally approached the altar of anal, and you feel its smooth, hot fingers wrap around your waist. You're surprised and you try to stand up and see who is behind you, but the venous stone wraps around your hands and prevents your from leaving the altar.

Out the corner of your eye, the horns of the demon shine in the pink room. Your clothes begin to feel hot, and then the threads gather and separate into thicker sections. Like snakes, the strands of clothing moves around your body and re-form themselves into a net bodysuit.
