Creature Bio: Void Panties

Yep, inspired by Secure Contain Protect (because it's cool) and by Monstergirl Encyclopedia (because it's a ton of allocishet nonsense and wasted potential). First creature of my KneecapRock's Big Book of Monsterfolk Project! Hope you enjoy!

Void Panties

These creatures may seem small and insignificant, but they're actually quite powerful. Void Panties take the form of ordinary human panties. Nobody knows where they come from, only that they appear in lingerie stores and other such clothing shops seemingly out of nowhere.

They are psychic creatures, and can detect life from up to 100 metres away. Before being observed, they will identify the most likely person to claim them as their own, and transform themselves to match their target's subconscious desires. If someone wants grey and lacey, plain and white, red and floral-patterned, or any other kind of panties, they will become as such.

They use their psychic powers to influence their target's subconscious: even people who would normally never wear panties can succumb to their manufactured appeal and claim the Void Panties for themselves. Should their target pass them over and decline to claim them, the Void Panties will become dejected, hiding themselves out of sight - such as on the floor underneath mobile shelves, at the rearmost part of a clothes rack, or even in the rafters - until they return to higher spirits and try again. No Void Panties have ever been observed to be declined by two or more consecutive targets, and it is unknown how the creatures would respond to such a scenario. Once a target claims a pair of Void Panties, they become the creature's permanent owner. The Void Panties psychically link to them and further compels their new owner to wear them.

Once their owner wears them for the first time, the Void Panties initiate telepathic communication between them: the Void Panties will convey what they are and what they can do for them (as will be elaborated on later). Their psychic abilities ease nerves: where someone may ordinarily panic after being contacted by seemingly eldritch clothing, said individual may willingly accept the Void Panties as their own. Still, people are given a choice: most people welcome the Void Panties into their lives, yet some do not.

If their owner denies them at this stage, the Void Panties will become irreparably disheartened. The Void Panties will make their owner forget that they ever communicated with them, and then they go dormant. Dormant Void Panties are, for all intents and purposes, completely ordinary. They are no longer detectable as anything other than regular panties and will never again interact with the world. It is unknown if their final act is to truly become normal panties or if they remain alive, simply choosing never to do anything again.

However, if their owner does accept them, they become overwhelmed with joy. The Void Panties will then allow their owner to see their more beastly aspects, such as soft tentacles and a face directed inwards on the crotch of the panties. Void Panties will pleasure their owner's genitals whenever so desired. Their tentacles are theoretically infinite in number and in length: tests have recorded a highest viewed number of tentacles of 507, and a longest length of 1220 metres. The only reason those are the highest known values are due to the limitations of the experiments and facilities, not due to limits of the creature. Void Panties can use their tentacles for a number of tasks and employ precise motor skills. Some activities Void Panties have been observed performing include giving back massages, aiding their owner when lifting heavy objects, assisting to maintain balance and preventing falls, and even using a pencil to write. Void Panties’ mouths host an entire pocket dimension (theorised to be the same pocket dimension that regularly houses their tentacles). If their owner has a dick, the Void Panties can use their mouths like a portal to hide it within them. Regardless of size, Void Panties can use this ability to make their owner's crotch appear perfectly flat without the need to tuck. Void Panties can alter their owner's genitals and, indeed, their entire reproductive system should their owner wish. This process is reversible, and can be performed as many times as their owner desires.

Since Void Panties are telepathic creatures, they share emotions and thoughts with their owner. They can telepathically speak with their owner whenever they choose. According to reports of known owners of Void Panties, they are quite fond of conversation and consider themselves to be their owner’s friend - every owner who has been questioned agrees that the feeling is mutual, considering the creature their friend as well. Void Panties gain great satisfaction by pleasuring their owners, and by otherwise seeing to their happiness.

Though they could, under some definitions, be considered parasites, every account points to a mutually beneficial and pleasant relationship.

Void Panties will of course allow their owners to undress out of them - namely for bathing, using the washroom, etc. - but they do not enjoy time not spent around their owner’s waist. The creatures are self-cleaning, never requiring to be tossed in with the laundry - though one account reports that manual washing in no way harms Void Panties, it is both unnecessary and unfavoured. There are no accounts of owners going without wearing their Void Panties for longer than 24 hours at a time, so it is unknown how Void Panties would respond to extensive periods without use. Needless to say, however, any long span of time without their owner would lead to sadness and dejection in the poor little creatures.

In rare instances, Void Panties and their owner mutually decide to merge with each other into a new being that is neither fully Void Panties nor fully human. These merged beings - to an unaware observer - appear to be normal humans, except for the fact that they are permanently wearing panties. It is unknown what happens when this occurs, as there have been no formally documented instances of this on record. It is theorised that this process is part of Void Panties’ reproduction cycle, but that is pure conjecture.
