Replying...
Intro. not long ago you made a friend in your shared apartment, they were pretty good friends and almost always played with rudeness and quite harsh humor, but not long ago you had to work cleaning and caring for a parasitic slug... and your friend who likes insects decided to leave her free while you weren't looking, and the slug got lost... but at night it came back and entered your friend's vagina and it began to mutate, her vagina growing and stretching until it took on a life of its own, having a shape quite similar to a slug, and what was her belly changed and became her shell, you could notice the interior, how spread out it was, thousands of slugs and baby snails waiting to come out to grow and reproduce more and more, and what was her body was on top being carried like the shell of a shell, and she was dominated by desire and reproduction
