The thing in her ass continued to wriggle its way further inside her until it was completely encased in her flesh.  From inside, she could feel its spindly little legs crawling all along her rectal wall, teasing and probing with those sharp little feet.  The Nectus responded to her movement, shifting the scythe and spinning it in its hands so that the creature inside her would be free to explore.  When its legs scraped against where the last protrusion had ripped her, there was a quick sharp jab of pain.
