Greetings, and welcome to this thread. Before we begin, a few rules:
  1. You may notice that WE talk in plural a lot in this thread and in the RPs we play with these kind of characters, even when OOC. This is a habit of ours which we use on purpose to amplify the feeling of the other person talking to a superior being. If you feel uncomfortable with it but you still want to play with us, just tell us in the initial message, and we will try to adapt, although as this is a pretty heavily ingrained habit, we can't promise some mistakes aren't getting through.
  2. This thread is about weird creatures invading the other person's body and changing them mentally and usually physically, which usually includes Non-Con, Unusual Transformations, especially Mind Control/Corruption and other Dark Themes. If you are not into these, now is your chance to run. If you are into these, then running may help, but once we make contact it usually doesn't take long...
  3. Although some people immediately think along with the kink 'parasites' of the kink 'breeding'. This is NOT the case here. The idea of pumping someone full with some kind of creature just for the sake of breeding them isn't really something we like. Sure, we do procreate the parasite and usually even spread it using the host, but making the host into an immobile sack of eggs isn't something that usually appeals to us.
  4. We usually only use one or two different kinds of parasite at a time, and not in huge masses at once. If you are looking to be overwhelmed by a load of different kind of parasites, you are not at the right spot.
  5. In our (many) eyes, we see transformation as 'changing a part of the body into something different or adding a part to the body that was initially not there'. This means that simpler 'transformations', like growing the breasts or hips a few sizes, isn't transformation to us but growth. Keep this in mind when approaching us.
  6. We are mainly looking for females, shemales (Penis and breasts) and herms (Penis, vagina and breasts) humanoids, but our usual favourite is a female human. Sorry boys and transgenders, but you usually don't do it for us. As for furries, there are times we feel attracted to certain furries, but more than not they don't work for us.
  7. If you play a human or similar aging character, we expect it to be 18+, no exceptions. We won't play with any characters ages 15, 16 or 17.
  8. If you have read this whole post and want to approach us, make sure to put '(MP)' in front of the title of the message so we know it's about this thread. It helps us keep everything sorted out.
With that out of the way, let's get to the main event.

The main idea of this thread is pretty well explained by the title: We would play a parasite, symbiote or another invasive creature that would infect the host (you) and change the host into doing the creature's bidding. This all happens either without the host's consent or without the host noticing what is happening to them. The changes usually come in the form of mental changes (subliminals, an extra conscious voice in the head telling the host what to do, a total identity whipe) but also physical ones (extra arms, a longer tongue, growing new features, the more unusual ones). After the host is properly infected, the creature usually forces the host to help infect other people, spreading its influence.

The details about what happens in the roleplay, like which changes are applied or what the creature looks like, are usually brainstormed with the host (you) after the initial contact. However, seeing as we do have some experience with people having no clue what kind of parasite they want, here are some types to help you out:

There are three steps to know what kind of parasite you would like. They are the following:

Step 1: Position
This decides where on or in the body the creature is located.
  • Internal (Endoparasitic)
    • An internal breed enters the host completely and stays inside the body for at most of the time. This is mainly useful for more covert infections where the host needs to be able to reintegrate with society without the parasite getting detected, but this isn't a hard requirement.
      • Preferred places: Inside the skull, womb, digestive system, lungs, underneath the skin, etc.
  • External (Ecto- or mesoparasitic)
    • External breeds stays (partially) outside the host. This means they usually connect to the brain by hijacking the nerves in the body, or directly attach to the skull. They are a bit more obvious than the Internal parasites because of the physical exposure, which adds a bit more effect of fear when it is revealed to a target.
      • Preferred places: Upper back, face, back or top of the skull, on top of the vagina, attached to the lower spine, etc.
Step 2: Infection Method
This decides not only how the host is infected, but also how the targets for the spreading of the parasites are infected.
  • Direct
    • This means the parasite needs no help from anything besides itself to reach and infect the host.
  • Consuming (Trophical)
    • These parasites get ingested by the host unknowingly and enter the body that way, usually through food.
  • Helped (Vector)
    • These parasites use a lesser host to get to the host they really want, for example by getting carried along by a mosquito. As a sidenote: Almost all humanoid hosts end up as vectors themselves as they (un)willingly will help the parasite spread after infection.
Keep in mind that with the infection method comes the entrance the parasites use to get to the host. This is mostly for the internal breeds, but try to imagine how the creature enters the body. With a trophical breed, this usually means the mouth, but with for example a direct breed, this can include openings like the ears, nostrils, vagina, but can also include more extreme entrances like the belly button or digging itself straight underneath the skin.

Step 3: Appearance
Now you have figured out where it positions and how it finds you, you need to think of what it looks like. This is something that can be completely different for everyone, but try to think of the previous steps and what would 'realisticly' work and wouldn't work with those options. Also try to keep in mind what you enjoy when it comes to physical transformations and if they have a common theme, as we usually base the parasite on the transformations or the other way around. Lastly, use your imagination. Don't just copy something straight from a fandom, like saying you want a facehugger straight from Alien. Instead, change the appearance and perhaps base it a mythical or existing creature. There are lots of times we used a squid, insect, slug or another non-vertebrate (and sometimes even a reptile or amphibian) as a base for the parasite's appearance. Just think of what you like, both in a normal fashion and in a kinky manner.

We also occasionally have our own ideas, in the form of regular ideas, fandom based ideas and even 'events' which are based on holidays like Christmas. Below is a list of these:

None yet!
None yet!
Easter Invasion!
With the nearby Easter holiday coming up, we are looking for ideas involving stereotypical Easter elements, like chocolate eggs that are actually parasite eggs, or a transformation involving bunny ears and tail but with a dark twist.

Lastly, we do want to point out that the most joy we get is from making a completely new and original idea, so we are always open to brainstorm new plots. In other words, don't be afraid to approach! Nothing ventured, nothing gained!
