Somnambula has heard of a villainous serpent lurking around harming other ponies, kidnapping them or destroying villages with his strong scales. She swore to make him stop his heinous acts, but she was unfortunate to be defeated by him. She was restricted of her movement by the snake’s strong, but comfortable coils. She was coiled from hoof to neck as she wasn’t able to turn her head. That was just what the snake needed as he filled her eyes with magical rings, placing Somnambula into a blissful trance. She was about to be devoured, but the snake thought she was kind of cute enough not to consume. He kept her as a lustful pet while he thought of gathering more lovely mares like her, creating a small harem.
I know vore is part of the original plot for the issue as Somnambula has to go inside the snake’s belly to remove a curse, but I’m not that into that kind of thing. /~\ I’ll still read the issue out of curiosity (and because pony and snake in the same comic, a dream come true).
