[skyzen] Parasite series of diamond worms 13 - Memories (Part 1) [xinsu]

A meek, bespectacled girl serves as an unhappy host to a chatty diamond worm that needs human semen to grow, and while she laments her slipping grades and envies her better-adapted sisters, the creature tempts her with an aphrodisiac potent enough to bend any man to her will—succubus powers included. But when that secretion gets tested at the family dinner table, her brother Da Min ends up pinning their voluptuous mother against the chair, panting and begging as she struggles to shove him off. This first half of a memories arc traces how one clumsy parasite and her reluctant host set a quiet household on the path to becoming an incestuous feeding ground.
