Test subjects X-88 or cibus limax, or as the scientists that created them nicked named them 'Marrow Slugs' were the latest creation of Westbridge Industries. The secretive bioengineering company has spent years developing potential solutions for the world's impending global food shortage draws closers due to spiralling population growth.

Their solution was the creation of a high protein, easy to farm life form, with a rapid reproduction cycle – the marrow slug. Looking much like a common, orange-brown garden slug, only much, much larger, the marrow slug performed superbly in all laboratory tests. The slug on average grows to 6 inches in length, although they can reach a size of 12 inches if well fed, with a diameter of between 2 and 6 inches. The marrow slug possesses two, tall and thick optical tentacles and excrete a thick, vicious mucus. This slime coats the creature and aids in both locomotion and the prevention of desiccation. The mucus is sweet and not unpleasant smelling and is currently being tested for its nutritional and lubricant properties.

The marrow slug thrives in temperate and tropical conditions, and performers extremely well in damp, warm and dark environments. They feeds on plant matter but can also digest various types of bio-waste and decaying matter. Fungus and certain types of yeast can also prove to be a food source for the marrow slug. Like many types of molluscs they are hermaphrodites and when 2 of more marrow slugs are kept in close proximity will breed quickly, with there numbers increasing rapidly.

Although meeting and in many areas exceeding Westbridge Industries project expectations there is one note of caution. Under no circumstances should marrow slugs be allowed to gain entry to human vagina or anus.

And that's were the role play can begin. Are you a female worker at Westbridge Industries who unwilling becomes infested with the marrow slugs? Or maybe you allow the fat, slimly slugs to ooze their way into your body? Have you harboured body invasion fantasies for years and this is your chance to make them come true?

Perhaps one day you come across a female scientist from WI, her belly swollen as if pregnant, slime oozing from her panties as she staggers along. You rush to help, not knowing the slugs within her will effect you too as she uncontrollably births them.

Or perhaps Westbridge Industries are even more sinister, and you're part of a trial to see what happens when a human female has marrow slugs introduced to her body. Are you screaming for them to stop experimenting on you, or do you spread your legs willingly?

If you're female IRL and want to RP any of these ideas, or just chat about them, then reddit chat and messages both work for me. I'm also on discord.
